Dual radome arrangement (15) comprising inner and outer layers (14,16) respectively transmissive to both modes of radiation operable in a detection system (11), and only one of the modes of radiation, and the outer layer (16) being selectively removable.

Multi-spectral radome

A two-piece despin obturator mounted on a forwardly inclined obturator ramp on the projectile sidewall has a ring-shaped body of nylon-6 and a wiper band formed from Plascon nylon. The two-piece design is relatively immune to damage in the handling and loading process but yet the wiper band enhances low pressure sealing while the ring, driven up the inclined ramp in the firing process, engages the lands of the spiraled rifling. The rotational velocity imparted to the ring is partially coupled as the inner surface of the ring rotates on the obturator mount of the projectile.
