Both sides fielded jet fighters in combat, with the UN forces using F-86s and the Communists deploying MiG-15s. The US and its allies unquestionably won the battle for the air, with US forces downing over 500 MiGs at a loss of less than 80 of their own jets.
Several times throughout the war, the use of an atomic bomb was discussed, though never employed. Ultimately, it would not have served any strategic purpose other than the destruction of civilian infrastructure. The closest the US came to using the bomb was in 1950, but its allies – particularly Britain – were severely opposed to it.
