different in design and appearance.
MK 76 MOD 5.—The 25-pound, solid metal-cast,
Mk 76 Mod 5 practice bomb (fig. 8-3) has a
teardrop-shaped body. It is centrally bored to permit the
insertion of a practice bomb signal cartridge. The after
body, covering the tail tube, is crimped to the bomb
body and has welded-on conical tail fins. The bomb has
single-lug suspension and is painted blue with
identification nomenclature s stenciled in white letters
on the body. The Mk 76 Mod 5 subcaliber practice
bomb is specifically designed to simulate unretarded
weapon delivery.
BDU-48/B.—The 10-pound BDU-48/B practice
bomb (fig. 8-4) is a thin-cased cylindrical bomb used to
simulate retarded weapon delivery. The bomb is
composed of the bomb body with a bore tube for the
installation of a single cartridge, a spring-loaded
retractable suspension lug, firing device, and box-type
fin assembly. The bomb is painted blue with
identification nomenclature stenciled in white letters on
the body.
