Beehive Antipersonnel Land Mine
Diameter at base: 8 inches.
Height: 4.5 inches (without fuze).
Total weight: 17 pounds (approximate).
Thickness of wall: 3/8 inch.
Color: Black.
Explosive filling: TNT.
Weight of explosive: 5 pounds (approximately).

Description: The mine is hemispherical in shape and its surface is uniformly serrated.

The central hole in the top of the mine is internally threaded to receive one of two fuze adapters. The first adapter takes either the plastic fuze used in the type 3 (a) ceramic and type 3 (b) wooden land mines, or the type 88 instantaneous artillery fuze from the centrifugal detents have been removed. The second adapter is constructed to take the fuze employed in the type 88 tapemeasure mine.

Both the serrations of the mine case and the thickness of the wall (3/8 inch) indicate that this mine was to be used as an antipersonnel weapon.

Employment: Antipersonnel mine.

Operation: The operations of the type 93 land mine fuze and the type 8 (a) ceramic land mine fuze are discussed under the respective mines.

The type 88 artillery projectile fuze from which the centrifugal detents have been remo-ved is fired by pressure on the firing pin head. Pressure on the firing pin head compresses the anticreep spring and the firing pin is forced into the primer.
