BOMB CONSTRUCTION: |
|
Resembles the AN-M65 1000 lb. G.P. bomb, taking the same tail assembly, arming wires and fuzes. The body is one piece cast steel and has a steel burster well 2.5" in diameter axially through it and expand in both the nose and base plate before welding; eliminating any possibility of decomposition of chemical fillers due to the presence of crevices. The base plate differs from that of the standard G.P. bomb in that it is a special forging welded to the case and containing the M1 needle valve. It also has a 1.25" filling hole closed by a soft iron gasket, a hard steel gasket plug and a threaded closing plug. The M16 booster is used in the burster well and con-sists of a waterproof fiber tube filled with 4.45 lbs. tetrytol. The standard 1000 lb. G.P. tail assembly consists of 4 fins welded to a sleeve which is held on to the base plate by a locking unit. Horizontal suspension is accomplished by dual lugs 7" on either side of the center of gravity or by a single lug 180° removed at the center of gravity. |
|
OPERATIONS: |
|
On impact with the ground the tetrytol booster breaks the bomb case into a few large pieces without causing the chemical agent to "flash". The initial cloud formed by the burst of this bomb when filled with (CG) covers an area of 100 yards in dia-meter within approximately 8 to 10 seconds. |
|
REMARKS: |
|
Attempts to disassemble the bomb or any of ist components are to be avoided except for the fuzes which may be removed provided it is necessary to return the bomb to storage. Release of the filler is dangerous and should not be undertaken except under exceptional circumstances. In handling any damaged chemical bombs or when conducting surveillance test by means of the M1 needle valve, personnel should be equipped with rubber gloves and a gas mask. |
|
M115A1 adapter booster can also be used in place of M115. |
