HMS Niger (J442)

HMS Niger (J442) was a reciprocating engine-powered Algerine-class minesweeper during the Second World War.

Design and description
The reciprocating group displaced 1010 - 1030 LT at standard load and 1305 - 1325 LT at deep load The ships measured 225 ft long overall with a beam of 35 ft. They had a draught of 12 ft. The ships' complement consisted of 85 officers and ratings.

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 2400 ihp and gave a maximum speed of 16.5 kn. They carried a maximum of 660 LT of fuel oil that gave them a range of 5000 nmi at 10 kn.

The Algerine class was armed with a QF 4 in Mk V anti-aircraft gun 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.

Construction and career
The ship was ordered on 9 June 1943 at the Lobnitz & Company at Renfrew, Scotland. She was laid down on 5 November 1944 and launched on 1 May 1945. The ship was commissioned on 21 September 1945.

In 1966, she was put on the disposal list and sold to BISCO for scrap in Silloth.
