¹⁄350

Micro Mir of Ukraine has announced the March 2016 release of kit AVSAVM9325, a British M-class Submarine in 1/350 scale.

According to Wikipedia:

The British Royal Navy M-class submarines were a small class of diesel-electric submarines built during World War I. The unique feature of the class design was a 12-inch (305 mm) gun mounted in a turret forward of the conning tower. Due to the limitations imposed on submarine armament by the Washington Naval Conference, M2 and M3 had their guns removed. M2 was converted to carry a small seaplane and M3 was made into a minelayer.

M1 was the only one to enter service before the end of World War I but did not see action. She was captained during her sea trials by experienced submariner Commander Max Horton after his return from the Baltic, and was later lost with all hands while on exercise in the English Channel near Start Point in Devon after a collision with a Swedish collier, SS Vidar, on 12 November 1925. The wreck of M1 was discovered by a diving team led by Innes McCartney in 1999 at a depth of 73 metres. Later that year the wreck was visited again by Richard Larn and a BBC TV documentary crew, and the resulting film was aired in March 2000.

M2 was converted to a seaplane carrier in 1925, a hangar replacing the gun turret. She was lost off Chesil Beach on 26 January 1932. It is thought that the hangar door was opened prematurely. M2 lies in much shallower water, 32 metres deep with the top of the conning tower only 20 metres below the surface at low tide. She is a popular attraction for local scuba divers with as many as six boats anchored above her on busy days.

M3 was converted to a minelayer in 1927 with stowage for 100 mines, primarily to test the mine-handling equipment of the Grampus class. The mines were carried on a conveyor belt which ran along her upper deck and covered over by an enlarged casing. The mines were laid through a door at the stern. She was scrapped in 1932 after the trials had been completed.

M4 was broken up before completion.

In 1924 all three completed members of the class were used to test hull camouflage to reduce the visibility of submarines from aircraft—M1 was painted grey-green, M2 dark grey and M3 was painted dark blue.
