General description: In its early stages of development, this rocket was designated Mk 19. It is constructed of a light aluminum alloy and carries a high-explosive charge. It is intended for use against large aircraft.

Rocket power is supplied by 16 grains of ballistic type propellant 19.2 mm x 350 mm. They are contained in the cylindrical barrel of the bomb, and are ignited electrically.

The nose section is ogival in shape, and carries the high-explosive charge. A nose well is provided to take a special small impact fuze similar to A-3 (a).

The tail section is constricted to form a venturi, and is fitted with fins, riveted in place, for stabilization. An error of 10 meters at a range of 500 meters is assumed by designers.

The launching rails, 180° opposed, are attached to the barrel of the bomb.

The data on this bomb is the result of incomplete investigation, and must not be consi-dered as specific, accurate information.
