Description: The M86 consists of the 90-pound Fragmentation Bomb M82, and a Pa-rachute Unit M5 which is screwed to the base of the bomb body in place of the normal tail fin assembly. Both units are issued separately and must be assembled prior to use.

The Parachute Unit M5 consists of a cylindrical container housing the parachute. The lid of the container is fastened by a latch, which is secured by the arming wire.

The bomb is fuzed with the Fuze AN-M120 or AN-M120A1 by using the Adapter Boos-ter M117.

Suspension: The bomb can be used in a bomb station having the clearance of a 500-pound bomb, and may be suspended singly or as a two-bomb cluster with the Cluster Adapter M12. One suspension lug is welded to the bomb at the center of gravity, and two suspension bands are issued with the parachute unit. The larger-diameter band is secured on the parachute unit to be used in conjunction with the suspension lug or the smaller-diameter band secured on the bomb body.

Operation: The arming wire, which is fastened to the bomb shackle, passes through the lug of the rear suspension band and the latch on the parachute container, but not through the fuze. This secures the latch and prevents the parachute from opening until immediately after release of the bomb. The arming wire which passes through the fuze is fastened to the parachute by the arming cord.

On release, the arming wire is withdrawn from the latch on the container. As the bomb falls, the air stream removes the lid from the container and allows the parachute to open. The arming cord is attached to the shroud line and is pulled as the parachute opens, thereby permitting the fuze to arm.
