Well, ballistically, the barrels of the cannons move backward almost instantly 
as the round travels up the barrel. The rearward movement of the barrel is 
called recoil. It's a simple action-reaction physics scenario. Hydraulics are 
used to keep the barrels from snapping forward instantly and crashing into 
their supports after full recoil. Hydraulic dampers are used to slow the 
movement of the barrel back into battery position, their original pre-firing 
location, to be ready for another round, as well as controlling the actual 
recoil. On a system with high resolution and excellent dynamic range one can 
hear the hydraulic "shock absorbers" slowing the return of the barrels to 
battery after the initial burst of sonic energy from firing the round. It's a 
sort-of ffffzzzzzztttttt or wwhhhhzzzzzztttttt type of sound.
