美国十分重视海军陆战队未来的远征作战能力,可军费又非常有限,所以决定对现役的H—1“休伊”直升机实施改进计划。该项计划将对现役的280架直升机进行改进,即将180架AH—1W“超级眼镜蛇”改进成AH—1Z,100架UH—1N被改进成UH—1Y。海军陆战队要求改进后的直升机,应在作战半径、飞行速度、生存力、机动性、载荷/火力、对舰船甲板的兼容性,以及无地效情况下的高空/高温性能等方面,有较大幅度的提高。改进后,AH—1Z直升机的最大起飞重量将比AH—1W增加25%;机内载油量将增加32%;悬停的有效载荷(海平面、高温天气、无地效)将增加
The United States attaches great importance to the future capability of the Marine Corps for its expeditionary combat capability. With very limited military spending, the United States decided to implement an improvement plan for the existing H-1 Hodge-I helicopter. This plan will improve 280 active helicopters, that is, to upgrade 180 AH-1W Super Cobra to AH-1Z and 100 UH-1N to be improved to UH-1Y. The Marine Corps requires improved helicopters that should be based on operational radius, flight speed, survivability, maneuverability, payload / firepower, compatibility with the deck of the ship, and altitude / high temperature performance without land-effect More substantial increase. As a result of the improvement, the maximum take-off weight of AH-1Z helicopters will increase by 25% compared with that of AH-1W; the loading capacity of aircraft will increase by 32%; the hovering payload (sea level, hot weather and no ground-
