The 18th Fighter Group (USAAF) was a fighter unit that suffered heavy losses at Pearl Harbor but recovered to operate over the Solomon Islands, New Guinea, the Dutch East Indies, the Philippines and Formosa.

The group was formed in Hawaii in 1927, and spent the inter-war period on the islands, taking part in Army-Navy manoeuvres and standard peace-time flying. The group converted to the P-40 in 1941, and was using that aircraft when the Japanese attacked Pearl Harbor. The group suffered heavy losses and was only able to get two aircraft into the air, both of which were quickly shot down.

The group needed some time to recover from this damage, but was soon able to being flying patrols from Hawaii. This was a short-lived role, and in March 1943 the group was allocated to the Thirteenth Air Force and moved to the South Pacific.

The group moved to the Solomon Islands, and provided air cover for the USAAF bases on the islands. They then moved on to flying bomber escort missions over the Bismarck islands as well as supporting the wider campaign in the Solomon Islands. The group helped support the invasion of Bougainville, providing part of the air cover on the first day of the invasion in November 1943. They shot down seven Japanese aircraft without loss.

In August 1944 the group moved to New Guinea, and converted to the long range P-38 Lightning. It was used to escort bombers on long range missions to the Philippines, Borneo and the Dutch East Indies.

The group was awarded a distinguished unit citation during the fighting on Leyte. On 10 November 1944 the group attacked a Japanese convoy bringing reinforcements to Ormoc Bay, pressing their attack despite heavy flak and Japanese fighter opposition.

In January 1945 the group moved to the Philippines, where it was one of the first groups to move onto the new strip at Lingayen. It was used to support the invasions of Luzon, Palawan and Borneo. They also carried out direct attacks on Formosa and provided escorts for bombers operating over a wide area, including French Indochina, Borneo and Formosa.

The group remained in the Philippines after the end of the war, before moving to Korea in 1950.
