Description
Body is black with yellow band around center. The tail extension and tail are gray.
The cylindrical steel body is crimped around the nose piece and screwed into the forward end of the tail extension. An inner cone is found at the forward end of the body which gives a "Monroe effect" on exploding. The tail cone which houses the fuze is screwed into the after end of the tail extension. The booster assembly is contained in the tail extension.
Three aluminum tail fins are attached to the tail cone by screws. They are braced by a single hexagonal strut and by a hexagonal end plate. (See modified bomb.)
Modified bomb: A container full of modified type 2 40mm bombs has been recovered. These bombs are filled with Japanese Army Mark 2 explosive (TANOYAKU—50 percent TNT- 50 percent RDX). A 5/16 inch layer of pure cyclonite poured in on top fills up the bomb body.
Evidently in an effort to reduce UXB's the arming spindle of recent bombs was lengthened about 1/8 of an inch. This increase allows the cup-shaped vanes to protrude further into the wind stream.
The end plate on the modified bombs is omitted. A 3/16 inch strut at the extreme end of the fins is substituted. A golden lacquered, thin, tinned steel is substituted for the older type aluminum tail fins.
Captured documents describe the use of this bomb in air to air bombing.
