An unmanned undersea vehicle system comprises an axisymmetrical cylindrically-shaped self-propelled undersea deployment vehicle of predetermined diameter, the undersea deployment vehicle having an amidships undersea weapon compartment. The weapon compartment includes elements for receiving a weapon and a buoyancy chamber positioned axisymmetrically within the weapon compartment. The buoyancy chamber is initially empty and has sufficient capacity so that it can be loaded with seawater whose mass approximates the mass of the weapon. The weapon compartment further includes controllable valves for enabling seawater surrounding the vehicle to fill the buoyancy chamber. A control element controls the deployment of the weapon by expelling the weapon from the weapon compartment and thereafter controlling the firing of the weapon. contemporaneously controlling the valves during weapon deployment to enable filling of the buoyancy chamber to maintain an axisymmetrical distribution of mass as the weapon is deployed.
