Modifications

Fairmile produced a large number of motor launches for the Royal Navy, of which the Fairmile "B" were designed as submarine chasers. They were designed for mass production and, to further speed production, they were completed with two engines rather than the three originally intended. The resulting loss of speed did not prove much of a hindrance and the craft proved highly versatile, a number being completed as minecraft or motor torpedo boats.

The Royal Australian Navy considered the design ideal for littoral warfare in Australasia and southeast Asia and assembled 53 of the craft starting in September 1942. A dozen were assembled in New Zealand and nine in South Africa, with some of the South African craft serving in the Arakan.
