US Bomb, 220 lb Frag, AN-M88




The 220 pound frag bomb AN-M88 has a body constructed of spirally-wound 13/16 inch square steel bar over a seamless steel tube which forms the base for the wrapping. Solid nose and tail forgings complete the bomb assembly. A fin assembly, either box type or conical type, is secured to the aft end. The conical type fin (M135) is standard for high altitude and/or high speed bombing. The nose and tail sections are threaded to accommodate nose and tail fuzes. Two suspension lugs are welded 14 inches apart on one side of the bomb body; a single lug is attached to the opposite side at the approximate, center of gravity. Approximately 19 percent of] the complete weight of the bomb comprises the explosive filler.

The 220 pound frag bomb AN-M88 is a later modification of the 260 pound AN-M81. It is lighter because of its thinner windings. Both bombs have the same outside. diameter; however, the smaller explosive cavity of the AN-M81 contains about 5 pounds less explosive filler. The physical characteristics of the two bombs are otherwise similar. The 260 pound frag bomb AN-M81 is more effective for fragmentation effect against materiel than an equivalent bomb load of 500-pound GP bomb, or 20 pound frag bombs. The casualty effect, however, against unprotected personnel by the 20 pound bomb is greater. The AN-M81 frag bomb compares similarly in effectiveness with the AN-M88 frag bomb.
