An assembly for vehicle deceleration and buoyancy comprises a pair of doors enclosing flotation bags inflatable for buoyant recovery of the torpedo. In operation, the doors are controllably forced open to an initial angle off a longitudinal axis of the assembly to a fully-deployed position by hydrodynamic forces of the movement of the vehicle. From the doors blocking the hydrodynamic forces, the vehicle decelerates. The hydrodynamic braking action of the doors reduces the time required to reach terminal velocity, thus reducing the depth the vehicle sinks and enabling recovery with less gas required for inflation.
