- Summary
- By 1939, the U.S. Air Corps Research Board decided among the needs in the liquid-cooled field were 1,342 to 1,491 kW (1,800 to 2,000 hp) flat engines for installation in bomber wings; requirements only attainable by an H type.
- Lycoming had already begun studies for a 24-cylinder H-2470 engine, just two O-1230 opposed engines pancaked together. The first H-2470 is believed to have passed a development test in 1942, and the Navy sent a letter of intent ordering 100 engines, for which the principal use was to be the Curtiss F14C fighter, the first carrier fighter designed with a liquid-cooled engine since 1925. However, before the new factory went into production, the Navy decided that it would be available in quantity too late to be of use in the war, and accordingly canceled its contract.
- This XH-2470-1 engine was flight tested in the Army Vultee XP-54in 1943, but not produced for similar reasons.
