| BODY CONSTRUCTION |
The bomb consists of an 8 in. A.P. artillery projectile with the base closed by a plug, which contains an adap-ter for the base fuze. The wall of the projectile extends beyond the base plug, and is threaded internally to re-ceive the rocket motor. |
| TAIL CONSTRUCTION |
The tail unit consists of four (4) pressed steel fins wel-ded to a conical section. The tail assembly is fitted over the venturi of the rocket motor. |
|
REMARKS – The propellant charge of the rocket motor consists of 38.6 lbs. of nitrocellu-lose powder having a burning time of 2.4 seconds. This rocket effect adds about 690 fps. to the velocity of the bomb, and allows a penetration of some 62.5 inches of concrete. A BETAB-170 DS and a BETAB-250 DS have been reported. |
