craft for Motor Launches and outfitted with AMES Type 11 and Type 15 fighter control radar to provide Ground-controlled interception (GCI) coverage for air defence of the D-Day landing areas. Of these ships, HMS FDT 216 was stationed off Omaha and Utah beaches, HMS FDT 217 was allocated Sword, Juno, and Gold beaches. HMS FDT 13 was used for coverage of the overall main shipping channel. In the period 6 June to 26 June Allied fighters controlled by the FDTs resulted in the destruction of 52 enemy aircraft by day, and 24 enemy aircraft by night. In the latter stages of World War II, some LSTs were fitted with flight decks that could launch small observation planes during amphibious operations. These were USS LST-16, USS LST-337, USS LST-386, USS LST-525, LST-776, and . Two others (USS LST-393 and USS LST-776) were fitted with the Brodie System for take off and landing. It has been estimated that, in the combined fleets assembled for the war on Japan, the tonnage of landing ships, excluding landing craft, would have exceeded five million tons and nearly all built within four years. Throughout the war, LSTs demonstrated a remarkable capacity to absorb punishment and survive. Despite the sobriquets "Large Slow Target" and "Large Stationary Target," which were applied to them by crew members, the LSTs suffered few losses in proportion to their number and the scope of their operations. Their brilliantly conceived structural arrangement provided unusual strength and buoyancy; was struck and holed in a post-war collision with a Victory ship and survived. Although the LST was considered a valuable target by the enemy, only 26 were lost due to enemy action, and a mere 13 were the victims of weather, reef, or accident. A total of 1,152 LSTs were contracted for in the great naval building program of World War II, but 101 were cancelled in the fall of 1942 because of shifting construction priorities. Of 1,051 actually constructed, 113 LSTs were transferred to Britain under the terms of Lend-Lease, and four more were turned over to the Greek Navy. Conversions to other ship types with different hull designations accounted for 116: 6 Miscellaneous Ships (AG), 14 Motor Torpedo Boat Tenders (AGP), 7 Self-Propelled Barracks Ships (APB), 13 Battle Damage Repair Ships (ARB), 39 Landing Craft Repair Ships (ARL), 3 Salvage Craft Tenders (ARST), 4 Aircraft Repair Ships (ARVA, ARVE), 1 Advance Aviation Base
