由于国防预算不断紧缩与新武器系统单价不断提高之间的矛盾突出,美国海军面临的最大挑战是如何保持其装备的现代化与效能。其跨世纪直升机更新计划有两个主要目标:一是将海军一线作战直升机由7种类型降为2种,到2020年时在人员训练、维修及后勤补给方面节约200亿美元;二是用新型直升机SH-60R和CH-60S替换海军所有现役直升机,以最新科技对付最新威胁。 SH-60R计划 SH-60R是SH-60B系统性能提升计划与SH-60F机载吊放式声纳改进方案合二为一的结果。SH-60B“海鹰”直升机与SH-60F“洋鹰”直升机是冷战的产物,所用的探测
As the conflict between the ongoing deflation of the defense budget and the escalating unit price of new weapons systems has highlighted the biggest challenge the United States Navy faces in maintaining the modernization and effectiveness of its equipment. Its cross-century helicopter renewal plan has two main objectives: First, reduce the Navy's first-line combat helicopters from seven types to two and save 20 billion U.S. dollars in personnel training, maintenance and logistical supplies by 2020; second, Helicopters SH-60R and CH-60S replace all active Navy helicopters, with the latest technology to deal with the latest threats.
