General: This fuze consists of a Nose Fuze Mk 137 Mod 2 fuze plus a tetrly burster tube 14.06 inches long. A steel collar is brazed to the upper end of the tube. A rubber gasket is inserted retaining disc. Between the wall of the burster tube and the inside wall of the burster retaining disc is left a clearance of approximately 0.03-inch. This clear-ance, in addition to the rubber gasket, allows the burster tube a certain degree of flexi-bility, which is desirable when installing the complete fuze assembly in the fuze adapter of the rocket body. |
|
Remarks: No disassembly of this fuze is authorized. |
