Britain was the only user of the Seafire.
20 FAA squadrons were equipped with the Seafire.
The Seafire made its first operational debut in late 1942 during Operation Torch (invasion of North Africa). These were on the HMS Furious. Four squadrons were equipped with the Seafire Mk IICs. The 801 Naval Air Squadron (NAS) used the Seafire Mk IB. During 180 sorties the Seafires shot down three aircraft, damaged three in the air, and destroyed four on the ground. 21 Seafires were lost, three being shot down, and the others because of the thick haze.
121 Seafires (15 Mk IICs, 106 L Mk IICs) were used in support of the invasion of Sicily. The were stationed on the escort carriers HMS Attacker, Battler, Hunter, and Stalker, and the fleet carriers HMS Formidable and Illustrious.
There were eight Seafire squadrons on the carriers HMS Formidable and Illustrious, and the escort carriers HMS Attacker, Battler, Hunter, and Stalker.
During the covering operations, 42 Seafires were lost to accidents. Most of these were the inexperience of the pilots in taking off from Escort Carriers with a lack of wind.
Seafire LR IIC
The Seafire LR IICs were first used by the No 4 Naval Fighter Wing in late 1943.
British Pacific Fleet
Admiral Sir Bruce Fraser became commander in chief of the new British Pacific Fleet on November 22, 1944. The No 24 Naval Fighter Wing was equipped with Seafire F IIIs and Seafire L IIIs. The 887 and 894 Naval Air Squadron (NAS) performed most of the fleet defense with 40 Seafires. The fleet also had 12 Fireflies, 38 Hellcats, and 73 Corsairs.
The HMS Triumph had Seafire F.47s which took part in the last combat of Seafires.
