据简式防务4月8日报道

5日，美国空军在研的AGM-183A空射快速响应武器（ARRW）—高超声速滑翔武器样弹的助推器首飞试验失败，试验没有完成助推器发射程序，样弹也没有从B-52H载机上释放。本次助推器首飞试验，旨在验证样弹的作战飞行速度并采集相关数据，同时检验样弹与载机的安全分离以及可靠操控。

Update: US Air Force’s ARRW fails first booster vehicle flight test

by Pat Host 08 APRIL 2021

The US Air Force (USAF)/Lockheed Martin AGM-183A Air-launched Rapid Response Weapon (ARRW) conventional hypersonic glide weapon prototype failed its first booster vehicle flight test on 5 April, according to a service statement.

The ARRW failed to complete its launch sequence and did not deploy from its Boeing B-52H Stratofortress heavy bomber carriage aircraft. The B-52H flew over the Point Mugu Sea Range near California, intending to fire the ARRW booster test vehicle. Instead, the weapon returned with the B-52H to Edwards Air Force Base (AFB), California.

This flight test was to demonstrate the booster’s ability to reach operational speeds and collect other important data. In addition to booster performance, the test vehicle was to also validate safe separation and controllability of the missile away from the carrier B-52H, through ignition and boost phase, all the way to separation of a simulated glide vehicle. The ARRW test vehicle was delivered to Edwards AFB on 1 March.

The service did not return a request for comment prior to publication. Lockheed Martin deferred comment to the USAF on 6 April.
