The choice of attack helicopter for the Japan Self-Defence Forces was made after test flights of two AH-1 helicopters, which took place in Japan between 1977-1978 which led to the conclusion of an agreement for the licensed production of the helicopters by japanese companies. The vehicle represented the closest option to an american AH-1F helicopter the JSDF could get. The AH-1S is a modified version, equipped with perspective navigational and electronic equipment, also, systems that decrease infrared radiation from the engine. The primary armament consists of a 20 mm 3-barrel General Electric M197 rotary cannon. Players will also be able to install rockets or ATGMs on hard pointed mountings: 7-tube M157/M158 launchers, 19-tube M200 launchers for close range targets, or 8 TOW ATGMs to destroy armored vehicles from distance.
