ABSTRACT:
A deployable boom is constructed of springly flexible members so that it is self-biased toward a long length deployed state. A drive mechanism is operative to actuate a reel and lanyard device to retract the boom to a short length storage state and to controllably permit the boom to be extended to its long length deployed state. Latches are operated by the drive mechanism to releasably hold the boom in the short length storage state.
