Design and description

The reciprocating group displaced 1,010–1,030 long tons (1,030–1,050 t) at standard load and 1,305–1,325 long tons (1,326–1,346 t) at deep load The ships measured 225 feet (68.6 m) long overall with a beam of 35 feet 6 inches (10.8 m). They had a draught of 12 feet 3 inches (3.7 m). The ships' complement consisted of 85 officers and ratings.[1]

The reciprocating ships had two vertical triple-expansion steam engines, each driving one shaft, using steam provided by two Admiralty three-drum boilers. The engines produced a total of 2,400 indicated horsepower (1,800 kW) and gave a maximum speed of 16.5 knots (30.6 km/h; 19.0 mph). They carried a maximum of 660 long tons (671 t) of fuel oil that gave them a range of 5,000 nautical miles (9,300 km; 5,800 mi) at 10 knots (19 km/h; 12 mph).[1]

The Algerine class was armed with a QF 4 in (102 mm) Mk V anti-aircraft gun[2] and four twin-gun mounts for Oerlikon 20 mm cannon. The latter guns were in short supply when the first ships were being completed and they often got a proportion of single mounts. By 1944, single-barrel Bofors 40 mm mounts began replacing the twin 20 mm mounts on a one for one basis. All of the ships were fitted for four throwers and two rails for depth charges.[1]

Construction and career

Launched on 18 March 1943 as AM 335, she was commissioned into the Royal Navy on 25 November 1943 as HMS Postillion.

She was sold to the Greek Navy in 1947 as Machitis. She was finally used as a target and sunk off Crete in 1984.

gollark: You should make a helper function to help with that.
gollark: You MAY have to actually store information.
gollark: Doesn't Haskell not like infinite types?
gollark: This is a bad explanation because this takes away any ability to make meaningful statements about god. For example, let's say you say "god is good". Well, if they can just entirely ignore laws of logic, they can be good, bad and potatOS at the same time.
gollark: It's not a very good spec.
