Mk 81

The MK 80 series Low Drag General Purpose (LDGP) bombs are used in the majority of bombing operations where maximum blast and explosive effects are desired. LDGP bombs are designed to be aerodynamically streamlined. Their cases are relatively light and approximately 45 percent of their complete weight is explosive. General purpose bombs may use both nose and tail fuzes and conical or retarded tail fins.

Snakeye was fielded in 1964 and used extensively since; the retarder tail (Mk 14 fins for Mk 81 250-pound) allowed low-level, high-precision attack while avoiding bomb-fragment damage to delivery aircraft and retaining a low-drag delivery option.
