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. The weapon was never mass-produced and was supplanted in 1964 by an improved design, the M139.
History
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 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.Specifications
The M134 bomblet was designed for the M190 Honest John rocket warhead. The bomblets carried sarin nerve agent and after the missile was fired the bomblets were released 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 in diameter with chemical agent.The Honest John held 356 of the 115 mm M134s. The spherical M134 was 4.5 inches around and constructed of ribbed steel. Its interior held about of sarin. The U.S. [Army Chemical Corps] originally planned to use the M134 as a VX dispersement method also, but later regarded this use as ineffective and scrapped the plan.
