1945 in aviation

This is a list of aviation-related events from 1945:

Events

• The probe-and-drogue aerial refueling system, in which the tanker aircraft trails a hose with a stabilizing conical drogue at its end which mates to a fixed probe mounted on the receiving aircraft, is perfected. It is superior to and replaces the looped-hose system which had been in use since 1934, and it remains in use today.^[1]

January

• January 1 – The Luftwaffe targets Allied airfields in Europe in "Operation Bodenplatte", occurring during the German withdrawal from the Battle of the Bulge.

In Lingayen Gulf, kamikazes damage the battleship USS New Mexico (BB-40), killing 30 – including British Lieutenant General Herbert Lumsden – the battleship USS California (BB-44), the heavy cruiser USS Louisville (CA-28) – mortally wounding Rear Admiral Theodore E.

Eleven U.S. escort aircraft carriers in Lingayen Gulf contribute another 143 sorties, and U.S. Army Air Forces planes also participate. In Lingayen Gulf, kamikazes sink a destroyer and a destroyer-minesweeper.^[11]
  • The second-highest-scoring American ace of World War II, U.S. Army Air Forces Major Thomas McGuire, is killed when his P-38 Lightning stalls at low altitude and crashes during a dogfight with a Japanese Nakajima Ki-43 (Allied reporting name "Oscar") fighter near Manapla over Negros Island in the Philippines.

It finds that in a war with the Soviet Union, the United States will have to seize forward bases from which to launch bombers for nuclear strikes, and that the United States will have to strike first to preempt a Soviet nuclear attack if the Soviet Union develops an atomic arsenal and the United States detects preparations for such an attack.^[146]
