SMS Hertha was a member of the Arcona class of steam frigates built for the Prussian Navy in the 1860s. The class comprised five ships, and were the first major steam-powered warships ordered for the Prussian Navy.
Design
Hertha was 73.32 meters (240 ft 7 in) long overall and had a beam of 12.9 m (42 ft 4 in) and a draft of 5.52 m (18 ft 1 in) forward. She displaced 2,113 metric tons (2,080 long tons) as designed and 2,504 t (2,464 long tons) at full load. The ship had short forecastle and sterncastle decks straight stem. Her superstructure consisted primarily of a small deckhouse aft. She had a crew of 35 officers and 345 enlisted men.
Her propulsion system consisted of a single horizontal single-expansion steam engine driving a single screw propeller, with steam supplied by four coal-burning fire-tube boilers. Exhaust was vented through a single funnel located amidships. Hertha was rated to steam at a top speed of 8 knots (15 km/h; 9.2 mph), but she significantly exceeded this speed, reaching 11.5 knots (21.3 km/h; 13.2 mph) from 1,510 metric horsepower (1,490 ihp). The ship had a cruising radius of about 1,350 nautical miles (2,500 km; 1,550 mi) at a speed of 11 knots (20 km/h; 13 mph). To supplement the steam engine on long voyages abroad, she carried a full-ship rig with a total surface area of 2,200 m (24,000 sq ft).
Hertha was armed with a battery of twenty-eight 68-pounder guns. By 1869, she had been rearmed with a battery of seventeen 15 cm (5.9 in) K L/22 guns and two 12.5 cm (4.9 in) K L/23 guns.
