Development & deployment
Developed for United States military forces in the 1950s, it was first used during the Vietnam War. The bomb consists of a cast steel case with 96 lb (44 kg) of Composition H6, Minol or Tritonal explosive. The power of the Mk 81 was found to be inadequate for U.S. military tactical use, and it was quickly discontinued, although license-built copies or duplicates of this weapon remain in service with various other nations.
Development of a precision guided variant of the Mk 81 bomb (GBU-29) was started due to its potential to reduce collateral damage compared to larger bombs, but this program has now been cancelled in favor of the Small Diameter Bomb.
- Mark 81 Snakeye fitted with a Mark 14 TRD (Tail Retarding Device) to increase the bomb's drag after release. The bomb's increased air-time, coupled with its (relatively) forgiving safe drop envelope, allowed for very low-level bombing runs at slower speed. Used commonly in the close air support (CAS) role in Vietnam (prior to wider availability of GBU precision ordnance). Nicknamed "snake", as in the typical Vietnam CAS loadout of "snake and nape" (250-lb. Mk-81 Snakeye bombs and 500-lb. M-47 napalm canisters).
