自2019年以来，美国一直在监视巴基斯坦的F-16舰队

此监视并不是什么新鲜事。自2019年美国批准其正在进行的部署以及PAF F-16舰队的1.25亿美元支持套餐以来，TST已被嵌入。

The U.S. has been closely monitoring Pakistan's use of the F-16 aircraft since at least 2019, with the monitoring reportedly tied to Pakistan's access to critical sustainment programs for the aircraft.

至少自2019年以来，美国一直在密切监视巴基斯坦对F-16飞机的使用，据报道，监视与巴基斯坦获得飞机关键的维持计划有关。

For instance, in 2022, the U.S. approved a separate $450 million deal for F-16 sustainment, covering various essential tasks such as structural integrity checks, engine maintenance, and software updates.

例如，在2022年，美国批准了一笔4.5亿美元的F-16维持交易，涵盖了各种基本任务，例如结构完整性检查，发动机维护和软件更新。

Pakistan's defence ties with the U.S. have cooled since the mid-2010s. In 2016, Pakistan sought to acquire 8 additional F-16C/D Block-52s under the U.S. Foreign Military Financing (FMF) program.

自2010年代中期以来，巴基斯坦与美国的防御联系一直冷却。 2016年，巴基斯坦试图根据美国外国军事融资（FMF）计划获得8个额外的F-16C/D块-52。

However, Congress blocked the subsidy, leading Islamabad to either pay the full price or abandon the deal. Pakistan ultimately chose the latter, putting on hold plans to expand its Fighting Falcon fleet. In subsequent years, the U.S. also blocked the use of military assistance to finance the Pakistan Army's (PA) purchase of 12 AH-1Z Viper attack helicopters, among potentially other equipment.

但是，国会阻止了补贴，导致伊斯兰堡支付全价或放弃交易。巴基斯坦最终选择了后者，并制定了扩大战斗猎鹰队的计划。在随后的几年中，美国还阻止了使用军事援助为巴基斯坦军队（PA）购买12架AH-1Z Viper攻击直升机的资金，这是可能的其他设备。
