Patent ID: 10202173

Abstract:
Mast systems are provided for use with an underwater vehicle. In one example the mast system includes a support base, a mast arm and a mast payload bay. The support base defines a base axis. The mast arm defines a longitudinal axis, and has a free longitudinal mast end and a mast mounting portion longitudinally spaced from the mast end. The mast payload bay is provided at the mast end, and is configured for supporting a payload. The mast arm is mounted to the support base via the mast mounting portion, and the mast arm is selectively deployable with respect to the support base at least between a retracted configuration, in which the mast end is at a first spacing with respect to the mast mounting portion, and an extended configuration, in which the mast end is at a second spacing with respect to the mast mounting portion, the second spacing being greater than the first spacing. The mast system is configured for operating in a marine environment.
