An oil tanker's inert gas system is one of the most important parts of its design.

The LCAC is capable of carrying a 60 short-ton payload (up to 75 tons in an overload condition), including one M-1 Abrams tank, at speeds over 40 knots. Fuel capacity is 5000 gallons. The LCAC uses an average of 1000 gallons per hour. [5] Maneuvering considerations include requiring 500 yards or more to stop and 2000 yards or more turning radius.
