 The ship was designed to reach 33.25 knots (61.58 km / h; 38.26 mph), but Lexington achieved 34.59 knots (64.06 km / h; 39.81 mph) from 202,973 shp (151,357 kW) during sea trials in 1928. She carried a maximum of 6,688 long tons (6,795 t) of fuel oil, but only 5,400 long tons (5,500 t) of that was usable, as the rest had to be retained as ballast in the port fuel tanks to offset the weight of the island and main guns. Designed for a range of 10,000 nautical miles (19,000 km; 12,000 mi) at a speed of 10 knots (19 km / h; 12 mph), the ship demonstrated a range of 9,910 nmi (18,350 km; 11,400 mi) at a speed of 10.7 knots (19.8 km / h; 12.3 mph) with 4,540 long tons (4,610 t) of oil.
