The source of the gas bubble doesn't seem to matter.

"...supercavitating vehicles can achieve high velocities by virtue of reduced drag via a cavitation bubble generated at the nose of the vehicle such that the skin fraction drag is drastically reduced. Depending on the type and shape of the supercavitating vehicle under consideration, the overall drag coefficient can be reduced by an order of magnitude compared to a fully-wetted vehicle.
