1. A projectile comprising:
- a projectile base;
an exhaust manifold defined within said projectile base; and
an initiator operable to release a working fluid from a storage tank in response to an acceleration of the projectile, the working fluid released through said exhaust manifold to at least partially fill a wake aft of the projectile during projectile flight.
