167:, were satisfied with their liquid-cooled engines and showed no interest in building air-cooled engines. Since the Navy was already a major buyer of Wright engines, it pressured Wright into purchasing Lawrance and building the J-1 itself, by informing the company that the Navy would buy no more of its existing engines or spare parts. To retain the Navy's business, Wright complied in 1923 and the Lawrance J-1 became the Wright J-1.

Many
Whirlwind engines were used in U.S. Navy aircraft, mostly in trainers, but also in some ship-based observation and fighter aircraft. As the engines were refined and their reputation for reliability grew, their use expanded to U.S. Army trainers and a wide range of U.S. civil aircraft, including

for the U.S. Navy. The Navy was very enthusiastic about air-cooled engines, which it considered better suited for naval use than liquid-cooled ones. Lawrance was a small company, though, and the Navy doubted it could produce enough engines for its needs. Despite urgings from the Navy, the major U.S.

In a 1928 report on transcontinental aviation, the author disclosed the cost of a typical five-seat commercial aircraft as $ 12,500, of which $ 5,000 was for one of the 350 200 hp
Whirlwind Engines available that year. The J-5 was the last of the original nine-cylinder Whirlwinds. In 1928, it

The J-5 Whirlwind, introduced in 1925, was a complete redesign of the engine with greatly improved cooling and breathing, further increasing its reliability and reducing fuel consumption. Among the visible changes was the much wider separation between the valves, for better cooling airflow, and

Over the next two years, Wright gradually refined the J-1 engine, introducing the J-3, J-4, J-4A, and J-4B. The changes improved the engine's reliability, cooling, and fuel consumption, but the basic design, dimensions, and performance were unaltered.
