Fuel weight 3,916 LT. Dimensions 899.4 x 113.7 x 33.0 x 58.1 (freeboard) feet. Range 6,050 (at 30 knots)-1,850 (at 50 knots) nautical miles.

Performance of a representative DFM-fuelled medium sized aircraft carrier (CVX) in 1975. Designed to operate as high performance aircraft, displacement 55,000 light tons and as dimensions 902 (waterline) x 114 (waterline) x 32.8 (ship draft) x 58.9 (ship freeboard) feet. Propulsion 4 screws. Horsepower 200,000 hp. Maximum speed 31 knots. DFM fuel weight 3,650 LT. Cruising speed 20 knots. Range at cruising speed 11,950 nautical miles based on 10 percent fuel reserve rounded to nearest 50 nautical miles.
