the port cabin door, along with a Robar Arms RC-50 rifle attached to the cabin via a bungee cord for disabling hostile light vessels. The kit is also capable of being used on the HH-65C aircraft. When so fitted the aircraft is designated MH-65C. Attack helicopters AH-1 Cobra M28 Series (Emerson TAT-141) The standard fixed armament for the Bell AH-1 Cobra AH-1G, AH-1P (formerly referred to as AH-1S Production), AH-1Q, and initial AH-1S models, this turret unit is similar to the XM64, but was capable of mounting two M134 Miniguns, two M129 40 mm grenade launchers, or one of each weapon. Miniguns fitted are capable of pre-set firing rates of either 2,000 or 4,000 RPM, while the turret itself has 114 degrees of motion left or right, 17.5 degrees of elevation and 50 degrees of depression (alternate sources describe 110 degrees in azimuth, 20 degrees of elevation and 50 degrees of depression for the M28E1 model specifically). Each Minigun is linked to 4,000 rounds of ammunition while each grenade launcher is fed from a 300-round magazine. The system is known to have four standard A variants, the M28/A1-A3. However, the actual specifics between variants is vague. The available information suggests that specific variants were mated to specific iterations of the AH-1 helicopter. The initial XM28/M28 were fitted to the AH-1G, as were the M28E1/M28A1. The M28A1E1/M28A2 was fitted to the AH-1Q, while the M28A3 (no developmental variation known) was fitted to the AH-1P/S helicopter. There is the possibility that the M28A2 could have been the first unit designed to work with the XM128/M128 Helmet Sight System (HSS) developed primarily for use with TOW armed AH-1s. XM35/M35 An armament subsystem providing a single M195 20 mm cannon on the port inboard pylon of the AH-1G. 950 rounds of ammunition were stored in boxes faired to the side of the aircraft. The system was primarily pilot controlled, but featured dual controls to be either pilot or gunner controlled. For this purpose the pilot was provided with a M73 sight. XM64 (Emerson TAT-102A) The TAT-102A (Tactical Armament Turret-102A) was the initial main armament for the AH-1G helicopter, though designed as an interim measure. It is related to the TAT-101 mentioned in the UH-1 entry. The turret mounts a single M134 Minigun with 25 degrees of elevation, 90 degrees of depression, and 180 degrees of motion in azimuth, with a slew rate of 80
