Abstract: A rollable mast system couplable to an undersea vehicle includes a mast made of a bi-stable composite material configured to roll onto itself in a first state and to stiffen into an elongated stable shape in a second state, and a head structure coupled to a distal end of the mast. The rollable mast system further includes a spool configured to support at least a portion of the bi-stable composite material in its first state and a roller in contact with the bi-stable composite material and configured to pay out the bi-stable composite material from the spool in a direction away from a hull of the undersea vehicle. The bi-stable composite material is in the first state as it passes from the spool to the roller, and the bi-stable composite material is in the second state after it passes the roller.
