What device is used to thermally protect the Mk
82 Mod 2 bomb?
How can you tell if first stage arming of the Mk
346 fuze occurs?
An adapter booster is needed to install mechanical
fuzes in the Mk 80 (series) general-purpose bombs. The
adapter boosters currently in use are the M148/T45E,
M148E1 (nose), and the M150/T46 (tail).
M148/M148E1/T45 (Series) Adapter Booster
The M148/M148E1/T45 (series) adapter booster
(fig. 1-7) permits the use of mechanical nose fuzes in
the Mk 80 (series) bombs. The adapter booster is
externally threaded for installation in the bomb fuze well
and internally threaded for installation of the fuze. The
casing contains the booster charge and is threaded onto
the base of the adapter.
The M148E1 adapter booster is similar in external
appearance to the earlier M148/T45 (series).
Differences are the nomenclature marking on the face
of the adapter booster collar, the words THERMALLY
PROTECTED in bold black letters, and a yellow band
around the adapter booster casing, which indicates that
it is loaded with explosives. The M148E1 was
developed for use with thermally protected bombs.
