Adapter booster T45E3 permits the use of a 2-inch thread size for mechanical or proximity fuzes in the new series and the low drag GP bombs, including Snakeye I.
Adapter booster T45E4 differs from adapter-booster T45E3 in the following respects: The aluminum sleeve in the T45E3 extends the length of the booster casing assembly, while the aluminum sleeve in the T45E4 extends only to the surface of the booster charge. The T45E4 also contains a metal closing cup between the fuze well and the booster pellet. With the exception of the above differences, the two adapter boosters contain the same components.
