Besides launching ships, another application of marine airbags is for salvage of sunken ships or shipwrecks, or other objects underwater. It is called a marine or ship salvage airbag. It uses the buoyancy of the airbag after inflation. Rubber salvage airbag is much tougher than PVC lifting airbags. Due to its heavy-duty capacity, it can be used for big sunken vessels.
