The M134 bomblet, developed as the E130, or E130R1 bomblet, began development in the early 1950s. While the weapon was not yet battle-ready, or ready for mass-production, in 1960, work on the bomblet dated back to at least 1953. By 1964 the bomblet design had been improved and the smaller M139 was

The warhead meant to carry the M134 was classified and went into production on April 14, 1960; the M134, however, was not yet ready for production. The M134 had a host of issues which impeded its development. Problems with the fuze system, and a tendency toward unacceptable pressure build-up in

and after the missile was fired the bomblets were released 5,000 feet (1,500 m) above their target. At the time of the sub-munitions' release a mechanical time fuze would cut the warhead's skin and the bomblets were released. The weapon could effectively saturate an area 3,300 feet

adapted for use with the rocket warheads utilized by the M134. Thus, the M134 was never mass-produced; by the time the missile warhead and the M134 were ready for production they had been supplanted.
