Abstract
A submarine periscope of the non-hull penetrating type has an extendable hoist (11) secured at one end to the submarine hull (2) and at its other end carries a sensor pod (8). Pod (8) is rotatable by a motor (13) carried by the hoist (11) and is electrically connected to sensory signal output devices (34,35) inside the hull (2) by a flexible cable (24) penetrating hull (2) at a gland (21) to which is fitted a rotatable signal transmission device (19). Cable (24) terminates at slip rings (32) secured to the transmission device (19) inside the hull (2). The transmission device (19) is rotatable by a motor (29) and motors (13,29) are both controlled by a controller (30) arranged to provide for synchronous rotation of pod (8) and device (19).
