== Specification ==

Hi,
the service ceiling is only 16765m according to the source (service ceiling=Dienstgipfelhöhe) the absolute ceiling is 19810m (absolute ceiling=max. Flughöhe).
I didn't edit it myself because I'm not sure how to enter the data, so both ceilings are shown.

== IAF £15 billion contract may still be up for grabs ==

It seems that BAE are paring down the cost £3.5 million per unit and have re-approached the Indian gov after some very serious disquiet in the Indian military community over choosing the Rafale.

== Typhoon max speed ==

Typhoon max speed is said to be mach 2 at high altitude, which dcorrespond to 2150 km/h and not 2450 km/h which correspond to mach 2 at low altitude...
:The source says "2.495 km/h in 10.975 m Höhe", which translates to "2,495 km/h at a height of 10.975 kilometers". There is no Mach number given. So if anything, shouldn't the Mach number be changed? At a precision of only one digit versus four, it's probably a lot less exact, too. --]<small>&nbsp;(</small>]<small>)</small> 14:56, 22 August 2012 (UTC)
:Correction: The official site does mention Mach 2.0 to be the maximum speed. Now I don't know what's correct. --]<small>&nbsp;(</small>]<small>)</small> 14:58, 22 August 2012 (UTC)

Royal Air Force specification is mach 1.8 (1900 km/h) . But we can assume that RAF limits the top speed to preserve airframe and engines lifespam. 2495 km/h (mach 2.3) isn't possible, for more than few seconds, as the composits parts of the airframe coud'nt support the resulting temperature (abaout 200°C). Old fighter could reach such speed because they were maid of metal : aluminium alloy allow speed up to 2600 km/h (heat wall) and steel alloy (like MIG-25) only allow higher speed. <small><span class="autosigned">— Preceding ] comment added by ] (] • ]) 11:35, 23 August 2012 (UTC)</span></small><!-- Template:Unsigned --> <!--Autosigned by SineBot-->

Composits parts of the airframe coud'nt support the resulting temperature? The SR-71 rudder is a composit part and good for Mach 3.5 and the nose cone and leading edge of a space shuttle. It's a big difference between cold-curing composit systems and CO2 annealed composits.--] (]) 09:00, 24 December 2012 (UTC)
:I'm not aware of the Eurofighter using carbon ceramics or other ceramic composites. If that would be the case, high temperatures would not be a problem, but as far as I know, only standard prepreg CFCs are used. --]<small>&nbsp;(</small>]<small>)</small> 11:17, 24 December 2012 (UTC)

:::The speed is listed in multiple places as 1550mph at 10975m. Reference 257 shows Mach 2+ from 28,000ft to 55,000ft, which is damn near identical to this official speed chart for a MiG-29.

:::http://img707.imageshack.us/img707/4430/l6mh.png

:::You can see that also tops out at over Mach 2.3. The limit of the Typhoon Titanium's diffusion-bonding was originally quoted as Mach 2+ because I worked on it. It was never quoted as just Mach 2. If you look at the Rafale and then the Typhoon you'll notice a clear difference. The Rafale has pitot intakes that are stealthier (in theory) but less efficient at high speed (above Mach 1.2 and especially so above Mach 1.6). The Typhoon has longer ramped intakes to minimise total pressure losses in the intake at high Mach. It is quoted in multiple other places as 1550mph:

:::http://www.ukairshows.com/aircrafttyphoon.html

:::and this obviously isn't at sea level. The 1550mph is very specific because it is not simply Mach 2 at sea level miscalculated. Mach 2 at sea level would be 15'''3'''0mph or 2448kph. Reference 256 is also an official source, so it should be Mach 2.35.] (]) 17:55, 21 August 2013 (UTC)

::::] - your first source there looks like you could have knocked it up yourself - what is its provenance? And you can't add anything to any article "... because you worked on it." Your Airshow source looks more respectable, but maybe not be considered a ] for technical aircraft specifications. So this seems to leave just "Reference 256"? ] (]) 18:23, 21 August 2013 (UTC)

:::::The first source in my post above is from an official performance spec for a MiG-29. If I 'knocked it up myself' how come you can see the Russian writing on the reverse side through the page? It is supposed to demonstrate that an aircraft capable of Mach 2+ from 28000ft to 55000ft (see reference 257 in Eurofighter page) is likely to top out above Mach 2.3. Reference 256 is from the Austrian airforce, which is very official and there are now 2 other sources backing this up. 1550mph crops up everywhere but unfortunately people who don't understand jack have divided it by the speed of sound at sea level to get the Mach.

:::::, , , ,

:::::Besides this, it's scientifically illiterate to have a wiki page that says 'Mach 2 at altitude' and then '1550mph afterwards'. They can't both be right and 1550mph is stated everywhere. Notice how the Su-27 says Mach 2.35 and gives the same speed of 1550mph:

::::::Maybe you're very clever with Russian writing and PhotoShop - how should I know? What a coincidence that these two aircraft should have the exact same top speed. But then, maybe I'm a "scientific illiterate" who "doesn't understand jack". ] (]) 19:52, 21 August 2013 (UTC)

:::::::It's not quite the same but many aircraft are designed for a similar role and have similar performance. Seriously? 'Clever with Russian and photoshop'? Be serious.] (]) 22:09, 21 August 2013 (UTC)

::::::::You could simply provide the source of your image alongside it, to demonstrate its provenance. ] (]) 22:22, 21 August 2013 (UTC)

:::::::::Yes because everyone can demonstrate the provenance of everything they find on the web? The speed is 1550mph at 11km altitude which is Mach 2.35. This is plainly stated in Reference 257 and Reference 258 states Mach 2+ from 28,000 to 55,000ft, which is consistent with Mach 2.35 at the optimal altitude in between.

::(2495/3.6) / (1.4*287*216)^(.5) = 2.35 (of course it depends what value of gamma you use).

So basically you want to turn Misplaced Pages into an American encyclopedia of BS. I've listed 2 reliable sources showing Mach 2.35:

http://translate.google.de/translate?u=http%3A%2F%2Fwww.bmlv.gv.at%2Fwaffen%2Fwaf_eurofighter.shtml&sl=de&tl=en&hl=de&ie=UTF-8

and

Mach 2+ from 28-55,000ft

http://translate.google.de/translate?u=http%3A%2F%2Feurofighter.airpower.at%2Ftechnik-daten.htm&sl=de&tl=en&hl=de&ie=UTF-8

and so far I've listed several other supporting sources stating 2495kph. So unless you believe that's at sea level, it isn't Mach 2, it's Mach 2.35. You can't say Mach 2 and then say 2495kph at 10,975m because they're contradictory. <small><span class="autosigned">— Preceding ] comment added by ] (] • ]) 17:10, 28 August 2013 (UTC)</span></small><!-- Template:Unsigned --> <!--Autosigned by SineBot-->
:I want to head off an edit war and avoid people getting blocked. Regardless of what you believe is "right", or regardless of what ''is'' "right", this is obviously not a non-controversial change.

::::::Well what exactly do you mean by a 'secondary source'? What is there in between the primary sources listed and the other sources listed (an example would be good)? Furthermore the BAE SYSTEMS source states 1521mph, which I've explained in my calculation is around Mach 2.3 at the edge of the troposphere, which is almost invariably where fighter jets achieve top speed because it's the best trade-off between cool air and good air density for lift at lower alpha, which reduces drag. The only place these mph figures equate to Mach 2 is at ground level and that sure as heck wasn't where 1550mph was achieved. So far with have 2 primary sources listing 1521-1550mph(2495kph), which is obviously around 11km altitude by common logic, and a fairly specific source stating Mach 2+ from 28,000-55,000ft: http://eurofighter.airpower.at/technik-daten.htm This matches up favourably with this performance graph for a MiG-29 (which apparently I fabricated, in Russian, which I don't speak):

The only actual primary source is sitting on the Warton Proquis Information Management System and has a classification of 'SECRET'. In fact, only the header sheet is actually sitting on the system, the document itself is locked away in a fire-proof safe with back-up copies at Iron Mountain. One of the two primary sources does specify an altitude, and then there's just the simple fact that the Vmax altitude given by the Austrian Airforce is roughly true for most fighter jets. This is a primary source backed up by common knowledge, more than enough to base a calculation on. There is a reason why fighters achieve top speed at this altitude: https://en.wikipedia.org/File:Comparison_US_standard_atmosphere_1962.svg and https://en.wikipedia.org/Flight_envelope and https://en.wikipedia.org/File:AltitudeEnvelopeText.GIF. Furthermore using a = sqrt(Gamma*R*T) to calculate the speed of sound is very much not 'original research'. It's a very well established formula that's expressed on your own pages. https://en.wikipedia.org/Speed_of_sound#Speed_in_ideal_gases_and_in_air Here R is expressed in J/molK which divided by the molar mass gives J/kgK, i.e. (8.31451J/molK)/(0.0289645kg/mol) = 287J/kgK. This is kind of why I get annoyed discussing things here. I'm stating things that are indisputable facts as an engineer in conjunction with a primary source, and being told that they are merely 'opinions' or 'original research'. The link I've posted also specifies the speed of sound at 11km altitude (295m/s or 294.6m/s exactly using formula) and the temperature there (273-57) = 216K.] (]) 17:22, 29 August 2013 (UTC)

There is no problem making simple calculations (assuming we have all the relevant parameters) when we are missing a reference for a specific value. But this is not the case at all here.

So the calculation is based on speed and altitude figures from a primary source, backed up by speed from another primary source and an assumed altitude. Note that 'Mach 2+' does not specifically contradict these values.

:::We've gone over this before a few times now. The source specifying 2495kph (1550mph) at 10,975m is a primary source and is very specific. The other primary source quoted is a manufacturer and specifically states 1521mph, which is a very close figure and it only requires a small stretch of logic and subject matter knowledge to know that this is at the edge of troposhere and not at ground level. Furthermore EADS (the other manufacturer) states '2+' http://www.eads.com/eads/int/en/our-company/What-we-do/Cassidian/Eurofighter.html. And so does this technical guide http://www.eurofighter.com/fileadmin/web_data/downloads/misc/TechGuideENG.pdf. So we have 2 primary sources agreeing with the mph figure, one of which states an altitude enabling a calculation and 2 other primary sources that state '2+'. So that's 4 primary sources that are not in dispute. Furthermore there are other seemingly well informed tertiary sources that state Mach 2+ from 28-55,000ft http://translate.google.de/translate?u=http%3A%2F%2Feurofighter.airpower.at%2Ftechnik-daten.htm&sl=de&tl=en&hl=de&ie=UTF-8 and this MiG-29 speed graph of unknown providence showing that it's entirely possible for that to correlate to Mach 2.3+ at optimum altitude http://img707.imageshack.us/img707/4430/l6mh.png.
::::Hello, consensus can and does routinely change when new information and new sources come to view so saying that we talked about it before is not an argument. I'd like to also remind you that the value for the Mach speed has been consistent in this article for the past 10 years at Mach 2.0. In addition, what you did in the previous paragraph is clear ], if you want to know why, "this MiG-29 speed graph of unknown providence showing that it's entirely possible for that to correlate to Mach 2.3+ at optimum altitude" was a dead giveaway. Lastly you misrepresented a couple of sources there, I left a note on your talk page on this.
::::So let's re-start. I think we all agree that the value Mach 2.0 do not aligned with 2,495 km/h and we are trying to reconcile them. So far, the premise has been that 2,495 km/h is right therefore Mach 2.0 must be wrong. So what Z07x10 has been trying to do is 1) pretend that the sources stating Mach 2.0 do not exist. 2) Replace those sources by his own calculations based on ] cherry-picked values and "speed graph of unknown providence". 3) Rationalize the value Mach 2+ present in some sources so it really means 2.35, but only if you don't think about it too much.
::::Except that none of that is actually quite true. First it is very easy to find good quality sources flatly contradicting the 2,495 km/h value. Here are a few. BBC News (1,320 mph - 2,125 km/h), Daily Mail (1,320 mph - 2,125 km/h), FAS (2125 km/hr), RAF Typhoon Manual (1,320 mph - 2,125 km/h). The RAF Typhoon Manual is a very high quality secondary source as it is a official RAF title and it probably the best source we have here. They are all consistent with Mach 2.0. We also have numerous quality secondary sources stating the Mach speed at Mach 2.0 making any attempt at doing personal calculation a complete waste of time. Among those sources are Jane's All the World's Aircraft (page 278 of the 2004-2005 edition) which is already used throughout the article so is perfectly valid to set the Mach speed, and the official eurofighter.com (Z07x10 falsely claimed that the source said Mach 2+, it actually says Mach 2.0, twice). Lastly about the 2+ value. In fact, most sources do not say Mach 2+, instead, they say Mach 2.0+. The additional 0 is quite ]. Mathematically, it means that the value must be lower than Mach 2.1, completely ruling out Mach 2.35.
::::So, given that 1) we have no source whatsoever for Mach 2.35 but many for Mach 2.0 including JANE and eurofighter.com. 2) we have several high quality sources including the BBC and official RAF titles (The RAF Typhoon Manual) giving 2,125 km/h. 3) Mach 2.0+ means at best Mach 2.0999 and 4) 2,495 km/h is the exact conversion of Mach 2.0 at sea level so could be easily explained by someone not familiar with the concept of Mach speed making a mistake, I think a clear picture is starting to emerge here. In the Mach 2.0 - 2,495 km/h pair what is wrong is not the Mach value as initially thought, it is the km/h speed that should be 2,125 km/h. We have numerous high quality secondary sources to confirm it and get a consistent non ] set of values. Any additional thoughts before I change the article with Mach 2.0 and 2,125 km/h ?--] (]) 07:13, 21 September 2013 (UTC)
:::::This may come as a shock to you but 'Haynes' do not produce official Typhoon manuals or performance specifications. They're produced at BAE SYSTEMS in Warton Aerodrome by people like me and are referred to as ODMs (Operating Data Manuals), AFRCs (Aircrew flight reference Cards) and Performance Specifications. The last two of which are classified and the only true source of data. Just to blow your 'sources apart completely. In the Haynes Manual link you posted (secondary source at best) it states take-off to 40,000ft in 30s in one place and also states brakes-off to 40,000ft in 90s in another. Take-off taking 8s, clearly a contradiction of itself. The Eurofighter tech guide is again a secondary source. This is important to understand because neither Haynes, nor the Eurofighter tech guide, nor Jane's are written by people with access to the official performance specification or official data. This is why on page 18 of the tech guide it shows the Typhoon with 20 different stores, only 9 or 10 of which have actually been qualified if you count the (E)GBU-16 as an EPW II and lump all Eurofighter nations together as one.
This is my response to your subjective interpretation of significant figures that I've also copied to your talk page: I don't accept that Mach 2.0+ excludes figures higher than 2.1 and if there is a page stating this on Misplaced Pages it needs to be adjusted. It means the same as Mach 2+ in this case. Meaning is always specific to context and the fact that some websites write '2.0+' was a choice, because no one has officially ever stated, in person, Mach 2.0+. Let's face it, to give 1dp and then add '+' is kind of nonsense. It's more likely to be an auto-formatter choosing the number of significant figures/dps just like on Misplaced Pages. And in the case of the Typhoon this interpreation is confirmed by the Austrian Airforce primary source stating '2495kph at 10,975m'. and BAE SYSTEMS stating '1521mph'.
Furthermore Mach 2.0 at sea level is 2448kph not 2495kph and the Austrian Airforce clearly state an altitude.
'''The consensus reached so far is based on two primary sources stating '2495kph at 10,975m' (Austrian Airforce) (which is very specific and specifies an altitude enabling a simple calculation) and another primary source (BAE SYSTEMS) stating '1521mph', which again is not Mach 2 at sea level, which would be 1530mph and is clearly not at sea level.''' The other primary sources state Mach 2+ or Mach 2.0+ depending on their formatting preferences. The decision to add or not a dp is aesthetic not mathematical in this context and, in the face of the aforementioned sources, the best interpretation is that it simply means 'more than Mach 2'. The inclusion of a digit doesn't always have significance even on Misplaced Pages, e.g. does 11,000 lb mean less that 11,050 lb, or less than 11,500lb? And your maths is also wrong, if something is rounded to 2.0, that means less than 2.05 not less than 2.1, so mathematically you aren't even correct assuming your reasoning was correct. You're also wrong that speed has ever been generally accepted as Mach 2.0. It has always been Mach 2+, ever since I was working as an undergrad at BAe Brough in 1997. So in summary:
Austrian Airforce (Primary Source in possession of actual performance specification) - 2495kph @ 10,975m = Mach 2.35 at ISA conditions.
BAE SYSTEMS (Primary Source manufacturer in possession of actual performance specification) - 1521mph = Mach 2.3+ at or above troposhere.
EADS (Primary Source manufacturer in possession of actual performance specification) - Mach 2.0+ which in context means 'over Mach 2'.
The only sources that state otherwise are secondary or tertiary sources not in receipt of the performance specification or possibly some instances where a kid on work experience has been given a task of web page design. Instead of grasping at straws and wasting people's time, try and find something specific from primary sources before coming back and wasting my time in having to type a response on my weekend. The Austrian Airforce is a primary source and has given very specific details with speed and altitude, so I can't grasp the reasoning of some people. Are the Austrian Airforce liars? Is that the case being put forward?] (]) 11:05, 21 September 2013 (UTC)
:Hello, I actually thought we were at an impasse here but fortunately you last made me realise what the disconnect was. And this is my fault as I should have mentioned that before since you are relatively new to Misplaced Pages. On WP, we really only want secondary sources. From the ]: "Misplaced Pages articles should be based mainly on reliable secondary sources." Please read that page carefully as well as ]. We use primary sources only when secondary sources are not available which is not the case here. This is why JANE's, the Eurofighter tech guide and the RAF Typhoon Manual are actually very, very good sources for this article and that's why JANE's is widely used across WP because they are the kind of sources that we want. They will also trump any primary source. So, that said, I'll give you some time to familiarize yourself with those WP policies and if there are no additional objection, I'll update the article with what those high quality secondary sources say (Mach 2.0 and 2,125 km/h). --] (]) 16:39, 21 September 2013 (UTC)
::The policy can't possibly say that. That's basically the equivalent of accepting the word from the guy down the road instead of the people who build and fly the plane and are in receipt of the full facts. What I would hazard a guess to as regards your misunderstanding of the rules is that secondary sources are used when primary sources could be tainted, or have heavy agendas, e.g. court cases and political incidents. Then it would be appropriate to use secondary sources or other unbiased primary sources. In a matter like this, secondary sources are not really 'sources' at all, in that they are not the actual 'source' of any information they provide. In this case here we are dealing with a specific fact 'speed' which can only be reliably taken from those who have tested it, measured it and recorded it in a document. Neither Haynes nor Jane's have done this. You'll also appreciate wrt the policy, primary and secondary sources are somewhat entwined. Is the Austrian Airforce reading from the Performance Spec a primary or a secondary source? They are clearly one step removed from manufacture as a customer and the people writing websites at BAE and EADS are also not the ones doing the actual testing. From this perspective the aforementioned sources are secondary sources providing a reliable commentary having viewed the primary sources. Haynes and Jane's are now tertiary sources who have not had access to the primary sources and only have restricted access to the information via people who have, or sales executives from those companies speaking from bullet points, or pilots who typically fly the aircraft with 3 drop tanks and have strict guidelines about peacetime operating limits. Supercruise with just AAMs is Mach 1.5 but with 3 drop tanks and 4 EPW IIs it's Mach 1.2 or less. Hopefully you can see the problems associated with taking figures from journalists and trying to categorise primary and secondary sources too rigidly. I think the article as it stands uses the best sources available as regards those who have access to the actual indisputable genesis of the information.
::As an aside I can't understand where all the dispute comes from. Nobody ever questions the maximum speed of a Tornado being Mach 2.27 with 15% less thrust and 30% more weight but OMG, add Mach 0.08 for the Typhoon and Arrrrgh WWIII.] (]) 21:50, 21 September 2013 (UTC)
:::Hello, First as I already explained to you, on WP " articles should be based mainly on reliable secondary sources." Please see the policy pages ] and ]. Those policies are the same for everybody and they are non negotiable. If you don't believe me, I invite you to go to the ] so you can ask other editors to confirm. Air force sites are primary sources, JANE's and the RAF Typhoon Manual are quite evidently secondary sources (and very high quality). We don't have any tertiary source here as tertiary sources are encyclopedias. Please read ] carefully as they were already pointed out to you. Again, if you don't believe me, you need to go to ] and ask.
:::Now, let's move this along. Your core argument here is that (and I quote): "In this case here we are dealing with a specific fact 'speed' which can only be reliably taken from those who have tested it, measured it and recorded it in a document" and you use the Austrian Air force official website as a source. Well, as it turns out, Austria is not the only country with an official air force website, Germany, the UK and Italy have one too. For your argument to be valid, all values '''must agree''', because same aircraft, same tests, same measures must give the same results. So, this is exciting, let's check if that the case. Italian airforce "maximum speed Mach 2.0" (different value). German air force "Höchstgeschwindigkeit Mach 2,00" (also different value). RAF Max speed: 1.8Mach (new different value). So we have 4 websites of equal importance with 4 different values for the maximum speed and absolutely no way to know which one is right (and at least 2 of them are wrong). Z07x10, I sorry to inform you that your argument is therefore demonstratively false. Incidentally, this is why we rely on secondary sources such as JANE's because primary sources contradict themselves all the time.
:::The bottom line here is that 1) not only the Austrian Air force site cannot be used for the maximum speed, but all 4 sites are not reliable sources as they contradict each other, if the article uses any of them, we will have to find other sources. 2) since primary sources are in conflict, we must rely on secondary sources (and that what we should do anyway) to set the top speed. I will now update the article with the 2 reliable secondary sources we have for this value. Any attempt to change those with a primary source will be reverted. --] (]) 07:16, 22 September 2013 (UTC)
:::You are now participating in an edit war by deliberately making disputed changes against that agreed by consensus. Haynes is not a reliable source for anything other than car maintenance instructions. The logical conclusion is that most air forces have chosen not to be specific as regards top speed. The RAF figure has already been ruled out as unreliable by consensus in the large discussion before you joined in that you've conveniently chosen to ignore, it also quotes 2.0 elsewhere on the same site. You'll also note that the german airforce quote the dry engine thrust as 70kN then 60kN on the same page http://www.luftwaffe.de/portal/a/luftwaffe/!ut/p/c4/04_SB8K8xLLM9MSSzPy8xBz9CP3I5EyrpHK9nHK98sS0NL2s1JJivdTSony9ktTkjDz9gmxHRQCVxGXO/#par3. The wing area has also been approximated to 50.00m^2 (51.2m^2 - wiki). Clearly not reliable. The original official release was Mach 2+, so many people just quoted Mach 2. However, we now have more recent information from 2 reliable sources that contradict this, one of which specifies an altitude, which cannot be ignored. 2495kph at 10,975m is extremely specific and the German Misplaced Pages page has reached the same conclusion entirely independent from my input https://de.wikipedia.org/Eurofighter_Typhoon.
:::With respect to contradictions, you've quoted a Haynes article that contradicts itself in the space of 1 page. As regards 'magazines' in general (e.g. Janes, Air Forces Monthly), I grew reading car magazines, like many teens, and if I had a pound for every time they disagreed or got something wrong, I'd be very rich and the hardbacks published were even worse. 'Secondary sources' are in conflict too, especially as regards supercruise, and the sources you describe as secondary are arguably tertiary as they have never laid eyes on the primary source. A true secondary source needs to have access to the primary source. The level of a source (primary, secondary or tertiary) is debatable and we should focus on a commonsense approach rather than rigid categorisation of sources. As an example, if I produce datasheets like these http://www.americanordnance.com/pdf/Tow.pdf http://www.orbital.com/NewsInfo/Publications/Coyote_Fact.pdf, as I have done for the relevant wiki pages, are you seriously suggesting that a magazine article or a page from Haynes on line should be able to take precedence over such sources. May as well close Misplaced Pages if that's the case. ] (]) 10:45, 22 September 2013 (UTC)
::::Wait, wait, just realized something. You didn't pick 2495kph and 10,975m over all the other higher quality sources just because they are precise right? Please tell me that's not the what you did?--] (]) 13:52, 22 September 2013 (UTC)
::::No I ignored the other lower quality sources for the reasons already mentioned. The legacy figure was stated as 'Mach 2+', which was stated in many places as either 'Mach 2+', 'Mach 2.0+', 'Mach 2' or 'Mach 2.0'. All those figures derive from the legacy release of information. 2,495kph (1550mph) at 10,975m is a new figure that states a specific altitude as well as a speed and it comes from an airforce. The figure is backed up by '1521mph' quoted by the plane's manufacturer and '''the German wiki has drawn the same conclusions http://de.wikipedia.org/Eurofighter_Typhoon this serves as a neutral 'third opinion' within the wiki community - see dispute resolution '3O''''.
::::Explain to me why you are adamant that a plane with a 5% higher thrust-to-weight ratio than an F-16 and ramped intakes vs an F-16's pitot intakes, is somehow slower than it. Now replace the F-16 with a Tornado with no supercruise ability whatsoever but ramped intakes that allow Mach 2.27 with reheat despite weighing 30% more than a Typhoon and having older engines with a 15% lower thrust rating. There's no logical rationale to your insistence that the speed is Mach 2.0. Here's what Airpower Austria says: http://eurofighter.airpower.at/technik-daten.htm Mach 2.0+ from 28,000-55,000ft.

Typhoon's ability to 'shoot down' the F-22 in the merge, which was known to the RAF for several years before the Luftwaffe found out, belongs in the Typhoon article. It does not want shunting off to a German-language page devoted solely and obscurely to that Luftwaffe unit -- unless you happen to be a publicist working for Lockheed Martin. This article bears obvious signs of sabotage, including notably the pretence that Typhoons flew only one mission in Operation Ellamy -- the RAF's part in supporting the Libyan revolution -- and that this mission only hit an 'abandoned tank park', and that Tornados had to 'spike' (designate) for the Typhoons because Typhoon pilots don't know what they're doing. All a complete and typically Misplaced Pages lie, of course. Typhoon flew hundreds of missions over Libya and dropped hundreds of munitions. Typical loadout was four 1,000lb Enhanced Paveway IIs and a couple of AMRAAMs. Typhoons often spiked for themselves, and they often spiked for Tornados to save the Tornados carrying a Litening pod. The RAF actually preferred a Typhoon-Tornado pair, making use of Tornado's air-to-ground radar and Typhoon's datalink and Defensive Aids Sub-System (in case of SAMs).

'The successful delivery of Paveway II from a Tranche 2 Typhoon is another step forward in the development of the platform's multi-role combat capability.'

::No, because it's designed as a multi-role aircraft and is being developed with the software upgrades needed, and, as noted in the other part of the edit summary you decided not to address, Typhoon has already been used in air-to-ground missions.

The aircraft has yet to self-designate. A point that the current article has been censored free of. Why cover up the steps being taken to give it even a modest capability?

BTW, there are plenty of other sources for this lack of capability.

] (]) 03:20, 12 April 2013 (UTC)

:I am not sure the ability to self-designate is a key factor in being multi-role, lots of aircraft use other aircraft and ground assets to designate, multi-role just means it does more than one job. Not sure of Hcobb's latest reference to the telegraph has been pointed as a reference to lack of ability when the article clearly says it has the ability to ground-attack, perhaps the wrong article has been used. ] (]) 13:10, 12 April 2013 (UTC)

::Air Vice Marshal Phil Osborn rejected reports that the RAF had insufficient Typhoon pilots trained in the ground attack role to mount operations in Libya although the National Audit Office reported last month there were just eight. AVM Osborn acknowledged that the full Typhoon ground attack capability would not be available until 2015, but said that they had enough for the current mission in Libya. A defence industry source claimed that the RAF had rapidly cleared "overzealous" red tape to allow pilots to drop their bombs.

So everything about that operation was contrary to standard procedures, and all the aircraft did was fly a bomb to a general GPS coordinate as part of a PR stunt. And we're going to help the RAF cover this up. ] (]) 13:25, 12 April 2013 (UTC)

::::::I am the one who did the initial revert. Hcobb, what you posted amounted to just saying "they did some training one day." That is not notable. As it is previously established in our article that the aircraft have been used to drop bombs operationally, ''publicity stunt or not'', that one day in April 2013 they happened to train dropping bombs is not, on its own, notable. It smacks strongly of the type of "list of events" type cruft we have been trying to remove from these articles. We need notable information that is not constantly added in the form of "on X day, something else happened." Simply the act of dropping bombs in training does not seem to be hugely notable as this had already occurred operationally. What '''would''' be notable is if this training was the first dropping of bombs using self-designation, such as with LITENING. That is quasi-implied in the Globalsecurity article as it says these were Tranche 2 aircraft, which can carry LITENING, but it never actually says that as the milestone (or, indeed, whether this test involved either LITENING or self-designation). Both since we want to avoid Globalsecurity and because of the current lack of notability, I removed it. If you or someone else can find a source saying that something ''new'' happened, like the additional capability of dropping laser-guided bombs with self-designation, I would definitely support adding that to our article.

::2 and 3 are related. As I put in the edit summary I find the Daily Telegraph to be a good source normally, and have used it many times for other defence related topics. <s>It's fair to raise</s> ]. In answer I am happy to state I do not have strong feelings on this article overall, or this specific issue, nor do I have any conflict of interest (not asked, but just for the record). I do however have concerns about the accuracy and objectivity of the cited article and therefore on the potential to mislead readers of this article. As well as the comments on Typhoons the article has some falsehoods and many many gross oversimplications. But to focus on the issue at hand:
::The article states "The RAF, too, is pitiably run down. Its main ability to make war today resides in just one combat jet, the disastrous Eurofighter Typhoon. This plane is so expensive to operate that just 98 of the 160 purchased are potentially flyable." So let's leave aside the fact that the author's contempt is blatant here. But just on the facts this is a gross oversimplification. In contrast, read this analysis from the ]:
:::" "On serviceability rates, the RAF is well within the top cohort of air forces around the world," Bronk said. "Modern combat aircraft are complex and maintenance intensive to operate," ...adding that "a regular deep maintenance/upgrade cycle for each airframe" is a standard fleet-management practice around the world. Having 55 of the service's 156 Typhoons in sustainment is normal, Bronk added, "and actually better than most comparable fleets in NATO and elsewhere."
::So if you are keen on including this "sustainment" vs "active" ratio, then in the interests of providing the full context you'd need to find and include the comparable servicability rates of all the other operators of the Typhoon? Germany has been reported as having much worse serviceability, e.g. It would also be necessary to provide the context that this active vs sustainment number is a common measure. The author misrepresents it as unique to the RAFs Typhoons because in his view its a "disastrous" aircraft. ] (]) 17:49, 18 March 2021 (UTC)
:::Hardly unique to have aircraft on maintenance, modification programmes, short or long-term storage, it would be of note if they were all flyable, again not really noteworthy for inclusion. 19:47, 18 March 2021 (UTC)
:::Also note the total fleet figures are way out in the business insider source as well, the RAF has just over 130 Typhoons so that makes the percentages generated wrong. ] (]) 19:57, 18 March 2021 (UTC)

I agree that this isn't the ideal situation because various weights and fuel loads are bandied about with nothing concrete but at least we're using the best available sources. This does leave a disparity with the empty weight but there doesn't appear to be a reliable source for that either. The only reliable secondary source says 16,000kg (35,200lb) for interceptor configuration which should theoretically include internal fuel and air-to-air missiles (6 BVRAAMs and 2 SRAAMs). This would weigh about 14,000lb combined (11,000 + + + 170lb), which is why I had adjusted the empty weight earlier (to 21,000lb) so that it at least mathematically matched the information from the available secondary sources.

2 and 3 are related. As I put in the edit summary I find the Daily Telegraph to be a good source normally, and have used it many times for other defence related topics. It's fair to raise WP:JUSTDONTLIKEIT. In answer I am happy to state I do not have strong feelings on this article overall, or this specific issue, nor do I have any conflict of interest (not asked, but just for the record). I do however have concerns about the accuracy and objectivity of the cited article and therefore on the potential to mislead readers of this article. As well as the comments on Typhoons the article has some falsehoods and many many gross oversimplications. But to focus on the issue at hand:
The article states "The RAF, too, is pitiably run down. Its main ability to make war today resides in just one combat jet, the disastrous Eurofighter Typhoon. This plane is so expensive to operate that just 98 of the 160 purchased are potentially flyable." So let's leave aside the fact that the author's contempt is blatant here. But just on the facts this is a gross oversimplification. In contrast, read this analysis from the Royal United Services Institute for Defense and Security Studies:
" "On serviceability rates, the RAF is well within the top cohort of air forces around the world," Bronk said. "Modern combat aircraft are complex and maintenance intensive to operate," ...adding that "a regular deep maintenance/upgrade cycle for each airframe" is a standard fleet-management practice around the world. Having 55 of the service's 156 Typhoons in sustainment is normal, Bronk added, "and actually better than most comparable fleets in NATO and elsewhere."
So if you are keen on including this "sustainment" vs "active" ratio, then in the interests of providing the full context you'd need to find and include the comparable servicability rates of all the other operators of the Typhoon? Germany has been reported as having much worse serviceability, e.g. It would also be necessary to provide the context that this active vs sustainment number is a common measure. The author misrepresents it as unique to the RAFs Typhoons because in his view its a "disastrous" aircraft. Mark83 (talk) 17:49, 18 March 2021 (UTC)
Hardly unique to have aircraft on maintenance, modification programmes, short or long-term storage, it would be of note if they were all flyable, again not really noteworthy for inclusion. 19:47, 18 March 2021 (UTC)
Also note the total fleet figures are way out in the business insider source as well, the RAF has just over 130 Typhoons so that makes the percentages generated wrong. MilborneOne (talk) 19:57, 18 March 2021 (UTC)

I agree with you. Mark83 (talk) 19:59, 18 March 2021 (UTC)

Agreed that no fleet will have 100% serviceability, but what is noteworthy is the number of aircraft which are "in active fleet management, which can include aircraft in storage (to preserve airframe hours)" but excluding aircraft which are in the process of being disposed of. That information is available, so I will have a look and update the article accordingly, if indeed it is not up to date. Springnuts (talk) 22:46, 18 March 2021 (UTC)
Updated - 101 in service (out of 139 total - which from the note in the table includes aircraft which "are in the process of being disposed of"). Springnuts (talk) 23:07, 18 March 2021 (UTC)
Can any editor find a RS for what happened to the balance of 21 which have been disposed of, and what is the state of the 38 which are in the process of being disposed of? Springnuts (talk) 09:24, 19 March 2021 (UTC)
While we wait for reliable source, FYI some have been canaballised for parts, Mark83 (talk) 09:48, 19 March 2021 (UTC)

Tranche 5?

Some news sources are calling the latest Tranche Germany are buying Tranche 5 not Tranche 4. Should we add Tranche 5 to the Production Summary Table? 2A00:23C5:CFAA:AC01:54E3:DB43:2137:9491 (talk) 11:43, 11 June 2024 (UTC)

Tranche 5 is being used to refer to aircraft which have received the Long Term Evolution upgrade or built with it as new. The German order for 20 (which hasn’t been formally placed yet) would follow on from their 38 Tranche 4 (Quadriga) and be delivered in the 2030’s. WatcherZero (talk) 08:47, 12 June 2024 (UTC)
The term "Tranche 5" appears in the article once. Shouldn't this be explained in some way? What does the "Long Term Evolution upgrade" include? 205.239.40.3 (talk) 09:13, 12 June 2024 (UTC)
