GA reassessment
Lockheed Martin F-22 Raptor
- Article (edit | visual edit | history) · Article talk (edit | history) · Watch • Watch article reassessment page • Most recent review
- Result: Consensus to keep. Article submitted for confirmation by an author. Outside input, while limited, was positive. CMD (talk) 16:37, 2 July 2020 (UTC)
This article has been significantly modified since its GA promotion almost nine years ago, with influx of new information as well as changes in the lead, major tuning of the prose, and rearrangement of certain sections. I believe the substantial changes warrant a reassessment of the article, although as a major contributor I don't feel that I should conduct an individual reassessment. Steve7c8 (talk) 22:20, 31 March 2020 (UTC)
- I had a read through and didn't notice anything major that would disqualify it from GA status. It is a little bit fan boyish, but most articles are here (people generally don't write about things they don't like) and it is not really that bad. I think it should stay a GA. AIRcorn (talk) 07:54, 21 April 2020 (UTC)
- I've tried to tune the prose for greater objectivity, for what it's worth. Steve7c8 (talk) 13:19, 21 April 2020 (UTC)
- Keep - Prose looks pretty solid in this article. The lede could be a tiny bit longer, to ensure it accurately summarises any pertinent design and history, as per the article. Images could also do with alt-tags. Thanks L150 21:27, 2 June 2020 (UTC)
Removing belly landing from Accidents section
This is frankly not notable, and it's one of several that has occurred. Steve7c8 (talk) 00:28, 7 June 2021 (UTC)

No mention of: possibility of shoot down the F-22 Raptor aircraft by a Syrian missile
“According to the Oklahoman newspaper Post, citing U.S. military sources that the F-22 Raptor crashed in the north of Jordan, sources tell about the possibility of shoot down the F-22 Raptor aircraft by a Syrian missile Syrian everything and happened near the Syrian border, while a military expert John Blu Reed told the newspaper that the shoot down of the F-22 Raptor confirmation that Syria has a defense system updated the S-300, S 400 missiles or rockets, U.S. expert also stated that U.S. relations – Russia will be even more strained if it is confirmed that Russia has provided to Syria missiles S 400.
On the other hand according to reports from the United States, according to the Los Angeles Times of America, the Syrian defense forces have shot down four missiles launched by the Americans type Tomahawk, sources tell us that it was the defense systems (Pantsir-S1) anti-aircraft missiles that have made that American missiles struck, and centered in the middle, the sources of Washington state that four missiles were launched to test the degree of defense of the Syrian forces, the sources have also confirmed that one of the main reasons in stopping aggression against Syria is the overthrow of the American F-22 Raptor crashed yesterday in the north of Jordan, also also deal with the part of the Syrian air defense missiles to the four Tomahawk, remember that Jordan is still home to its territory five F-22, and this was one of the main reasons to postpone the trial of aggression against Syria.”
Probably this information should be included in article since sources are US News papers… Calimero (talk) 19:20, 29 July 2022 (UTC)
- We would need to see the actual sources before discussing this. A forum for a game modding website isn't a reliable source. --OuroborosCobra (talk) 03:41, 31 July 2022 (UTC)
- The newspaper referred to in that post doesn't actually exist. This nonsense shouldn't be entertained. Steve7c8 (talk) 04:19, 8 October 2022 (UTC)
- Tail doesn't look like a F22; maybe an Iranian F14?
"Chrome coating"
Ok, I have a bit of a problem with the whole bit about the so-called chrome coating. The problem is, other than people having seen it, everything else is utter speculation. Now I know that much about this aircraft is still top secret, so in many cases speculation is all we have, but at least it's very reasonable and educated. In this case, it sounds more like those TV shows where they're trying to speculate on how UFOs function. It's just wild guesses, and that's how it reads.
My guess is that people often have a natural human-tendency to jump to the extremes of their imagination and forget to employ a little Occam's razor. It's probably something much more simple. The sources said these aircraft were spotted participating in actual Red Flag war-games as aggressor aircraft, rather than flying in some kind of testing arena, likely going up against other F-22s. I think it's just to make them look different, more like enemy aircraft so they're not easily confused with friendlies. But whatever the reason, I think we need something better than all these wild guesses. At most, we should just mention the sightings and leave it at that, at least until we have something that doesn't sound like we're tossing everything against the wall to see what sticks. Zaereth (talk) 22:46, 19 December 2022 (UTC)
- I agree with this. While it's clear that USAF has many upgrades to the F-22 planned, including its RAM coatings, there's nothing definitively confirmed about the disposition of the chrome-like coatings (which frankly look almost like an applique on top of the existing skin). I would also move to the upgrades section. Steve7c8 (talk) 00:31, 20 December 2022 (UTC)
- It's also worth mentioning that these jets, 04-4065 and 04-4070, are OT (Operational Test) jets based at Nellis, while development test is typically done with dedicated flight sciences jets like 06-4132 at Edwards. While it's not out of the question that upgrades may directly move to OT without being see at Edwards, it would definitely be unusual. Steve7c8 (talk) 00:51, 20 December 2022 (UTC)
- I think, given the evidence, and especially the fact that the source says they were flying as aggressors during aerial-combat training, that they just painted them a different color for the same reason football teams wear different colored uniforms. It's important to know who's who. I wouldn't be surprised if it washed right off with some soap and a hot-water pressure washer. The source also mentions them mounting mirrors on the nose cones, which the only reason I could think of for that is to increase the radar signature to, perhaps, (I don't know) appear on the scopes as a enemy aircraft. That all makes much more sense than trying to pass off a chrome-plated aircraft as being somehow less visible (which makes no sense at all).
- All of this, however, is just raw speculation without anything to back it up one way or another. We don't even know if it's chrome at all. Maybe it's just some metallic paint meant to resemble the aluminum of common aircraft. We just don't know, and there is no point in reporting on the things we don't know about. At this point, I would just call it a WP:RECENTISM. I say include the reports of sightings if we want, but avoid the speculation without any facts to back it up.

This sentence seems grammatically incorrect but I'm unsure how to rewrite it as I don't understand 100% the meaning.
"Customers for U.S. fighters are acquiring earlier designs such as the F-15 Eagle and F-16 Fighting Falcon or the newer F-35 Lightning II, which contains technology from the F-22 but was designed to be cheaper, more flexible, and available for export."
Any thoughts? Azx2 08:02, 5 February 2023 (UTC)
- Having re-read several times I now understand the meaning of the sentence and apologize for my initial failure to grasp the finer details of this construction. Azx2 02:40, 6 February 2023 (UTC)
Max altitude 65,000 feet
Is this worth a mention in the specs? Hcobb (talk) 10:45, 5 February 2023 (UTC)
- 65,000 ft is listed under "Service ceiling" in the specs table now. But there could be a difference between maximum altitude and service ceiling. -Fnlayson (talk) 16:10, 5 February 2023 (UTC)
- There is a difference. At 65,000 feet the air is incredibly thin, the sky above looks black and blue down below, and you can really see the curvature of the Earth. Control surfaces are extremely sloppy and slow to respond, engine speed is slowed and so is the rate of climb. There just isn't enough air to keep everything working at full potential.
- The max altitude a plane can go is called its absolute ceiling. This is when the craft can no longer climb any higher, and you can only fly at one speed (full power) and still maintain steady, level flight. "Service ceiling", on the other hand, sets a safety margin that is a little lower than the absolute ceiling, because it's very easy to lose control up above the service ceiling and end up in an unrecoverable spin. The service ceiling is defined as the altitude at which the maximum rate-of-climb has fallen to 100 feet per minute. This is still a lot higher than the cruise altitude, which is where the aircraft tends to operate most efficiently, and that's generally limited by what's called the maximum operational altitude. I don't know if that helps, but I do think it's a number worth mentioning. Zaereth (talk) 02:15, 6 February 2023 (UTC)
- I thought there was a difference, thanks. So are altitude records based on the absolute ceiling, in level flight? -Fnlayson (talk) 03:53, 6 February 2023 (UTC)
- Not sure about records. Service ceiling is something they usually determine during test flights, but not something pilots usually take the plane to in normal operation. Absolute ceiling often remains untested, simply because it is so dangerous. You're literally flying the plane just at the edge of buffeting, the ailerons don't have much authority and the vertical stabilizers (tail fins) aren't doing a whole lot to keep the yaw under control. And god help you if you hit a pocket of low pressure or turbulence.

Not that it can't go higher, but it's usually too dangerous to attempt it, but I'm sure some daredevils have tried. There's a reason absolute ceiling is called the "coffin corner", because, once you get there, there is really not much you can do without going out of control.
