M134 bomblet

The M134 bomblet was a U.S. chemical cluster munition designed for use in the MGR-1 Honest John rocket during the 1950s.

[2] 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.

[2] By 1964 the bomblet design had been improved and the smaller M139 was adapted for use with the rocket warheads utilized by the M134.

[3] Thus, the M134 was never mass-produced; by the time the missile warhead and the M134 were ready for production they had been supplanted.

[1] The weapon could effectively saturate an area 3,300 feet (1,000 m) in diameter with chemical agent.
