The Type 3 "anti-tank" hand grenade is a Japanese grenade produced from 1943 to 1945 during World War II. It was designed to destroy the Allies' tanks. There are three variants (sub-types) of the weapon: Ko (Type A), Otsu (Type B), and Hei (Type C).

History

Throughout

. The Type 3 had a simplistic design and was made from expendable materials. This made the weapon relatively easy to produce.

This Japanese grenade is extremely hard to find today.

Design

The Type 3 has an odd and cheap appearance. It has a tear drop-like shape. The grenade consists of a thin steel cone mounted on a wooden standoff head. The explosive is cast around the cone and covered by a cloth bag made of either silk or hemp twine. The upper extremity is made of a very basic impact firing mechanism. The hemp tail attached at the top serves as a stabilizer for when the grenade is in flight, thus ensuring that the target is struck successfully. When thrown, the Type 3's twine seemed to create a tail-like skirt.

The grenade has a penetration power of 70 mm (2.8 in). This shows that it exceeds the penetration of the Type 99 magnetic grenade.
