The Liberty L-12 is an American water-cooled 45° V-12 aircraft engine displacing 1,649 cubic inches (27 L) and making 400 hp (300 kW) designed for a high power-to-weight ratio and ease of mass production. It saw wide use in aero applications, and, once marinized, in marine use both in racing and gentlemen's runabouts.

The engine was also used in the RN-1 (Zodiac) blimp.
Automobile
The White Triplex
Based on aircraft use the engine provided a good power-to-weight ratio. This made it ideal for use in land speed attempt vehicles.
It was selected for two land speed record attempts.
Babs, a single engined vehicle
White Triplex, mounting three Liberty engines working in tandem
Both attempts set new records. Both crashed during further attempts, resulting in the deaths of the drivers and a newsreel cameraman.
Tank
World War I Mark VIII "Liberty" tank
As early as 1917 the Liberty showed good potential for use in tanks as well as aircraft. The Anglo-American, or "Liberty", Mark VIII tank was designed in 1917-18. The American version used an adaptation of the Liberty V-12 engine of 300 hp (220 kW), designed to use cast iron cylinders rather than drawn steel ones. One hundred tanks were manufactured at the Rock Island Arsenal in 1919-20, too late for World War I. They were eventually sold to Canada for training in 1940, except for two that have been preserved.
Inter-war, J. Walter Christie combined aircraft engines with new suspension design, producing a rapid and highly mobile tank. Using Christie's concept, Russian forces selected and copied the Liberty in the BT-2 & BT-5 Soviet interwar tank (at least one reconditioned Liberty was installed in a BT-5)[citation needed]. Demonstration of this tank was witnessed by the British, and Christie's design characteristics were licensed and incorporated into the British A13 design specification.
World War II Centaur tank, the last type to fit the Nuffield Liberty
As World War II loomed, Nuffield, producing British cruiser tanks, licensed and re-engineered the Liberty for use in the A13 (produced as the Cruiser Mk III) and later cruiser tanks, with an output of 340 hp (410 hp from the Mark IV version). In later British tanks it was replaced by the Rolls-Royce Meteor, an engine based on the Rolls-Royce Merlin aero engine, which offered greater engine power (600 hp).
Nuffield Liberty engines were used in British tanks of immediate pre-war and Second World War:
Cruiser Mk III (A13 Mark I) - Nuffield Liberty Mk I
Cruiser Mk IV (A13 Mark II) - Nuffield Liberty Mk II
Crusader tank - Nuffield Liberty Mk III, IIIA, IIIB, or IV
Cavalier tank - Nuffield Liberty Mk IVA
Centaur tank - a parallel version of the Meteor-engined Cromwell British World War II tank - Nuffield Liberty Mk V
Watercraft
HD-4 hydrofoil at the Alexander Graham Bell National Historic Site
HD-4 or Hydrodome number 4 was an early research hydrofoil watercraft developed by the scientist Alexander Graham Bell. In 1919, it set a world marine speed record of 70.86 miles per hour (114.04 km/h) powered by two 350 hp Liberty L-12s.

Inventor, entrepreneur, and boat racer Gar Wood set a new water speed record of 74.870 miles per hour (120.492 km/h) in 1920 in a new twin Liberty V-12 powered boat called Miss America. In the following twelve years, Wood built nine more Packard V-12 driven Miss Americas and broke the record five times, raising it to 124.860 miles per hour (200.943 km/h). He also won five straight powerboat Gold Cup races between 1917 and 1921, and the prestigious Harmsworth Trophy nine times between 1920 and 1933, at the helm of his Miss Americas.
Many gentlemen's runabouts, Gold Cup, and other race-winners were built with Liberty L-12 engines.
