Key point: A lack of resources and an overwhelming Allied materiel advantage had doomed Japan.
It is a fallacy that Germany was the only nation to develop combat jets in World War II. In truth, while Germany had the most advanced technology, all of the major powers had jet aircraft projects during World War II, including the United States, Britain, Russia, Italy and Japan.
The most well-known Japanese jet—and the only one that saw combat—was the Okha, a rocket-propelled and human-piloted kamikaze. But another Japanese jet actually flew before the war ended, and would have seen combat had it continued: the Nakajima Kikka.
Japanese scientists had actually studied jet engines as far back as the 1930s, despite little government support, and even a turbojet prototype by 1943. Tokyo also knew of German research due to Japanese observers who witnessed early tests of the legendary German Me-262 jet fighter in 1942, But it wasn't until the summer of 1944, when U.S. B-29 bombers began to pound Japan, that the Japanese Navy asked for the Kokoku Heiki No. 2, or Kikka ("orange blossom").
