The Arrow is the best missile system of its kind in the world, and represents a force multiplier for our future force. [50] AST USFT#2 was conducted at NAS Point Mugu a month later, on August 26. This test was aimed at examining the Arrow's ability to detect a splitting warhead of a separating ballistic missile.
During this period, the warheads were not protected by the various mandatory security precautions for nuclear weapons. [1] [2] The incident was reported to the top levels of the United States military and referred to by observers as a Bent Spear incident, which indicates a nuclear weapon incident below the more severe Broken Arrow tier.

The initial explosion catapulted the 740-ton silo door away from the silo and ejected the second stage and warhead. Once clear of the silo, the second stage exploded. The W53 thermonuclear warhead landed about 100 feet (30 m) from the launch complex's entry gate. Its safety features prevented any loss of radioactive material or nuclear detonation.
