In 1944, when the Mk.7 design reached a length of 203 feet, its designation was changed to landing ship medium (LSM). The new variant could attain speeds of up to 12 knots and saw usage in the Pacific. 558 were built. Mark 8 The 225-foot LCT Mark 8, intended for service in the Pacific, was developed by the British in 1944. One hundred and eighty-six Mk.8s were ordered; however, when the war ended, most were cancelled and scrapped, or sold directly into civilian service. Only 31 entered service with the Royal Navy. Twelve were later transferred to the British Army; these were initially operated by the Royal Army Service Corps, then by the Royal Corps of Transport. Between 1958 and 1966, the other 19 ships were transferred to foreign navies or civilian companies, converted for other uses, or otherwise disposed of. Mark 9 An even larger LCT Mark 9 was considered in 1944, but the design was never finalised and none were built. Armament The LCTs had a variety of weapons, with the British (40mm) QF 2-pounder "pom-pom" mounts being gradually replaced by the faster firing 20 mm Oerlikon cannon. The Bofors 40 mm was also widely used, and proved that the LCT was an excellent gunfire support vessel. Various machines guns were often mounted for self-defence from aircraft and small boats, often two to four in the
