To reduce drag the tip of the projectile could emit some air or gas at Mach 160 and that will simply blow the air in front of it away, and thus drag will be reduced. The projectile will have an air cushion around it, travelling at its own speed. Let us not forget, that with this speed the projectile will be out of the atmosphere in less than half a second.

At the drag areas (the nose, cockpit, sides) they could blow air from the plane in front to clear the still air away, thus putting the whole plane in an effective cushion, that will reduce the drag considerably. Less drag means either more speed or less powerful engines drinking less oil.

Sometimes old ideas are useful in a later age! A "bacon plane" could be 
quite the terrifying weapon in Muslim or Jewish countries.
