Design

Starting in 1940 there was interest in a carrier based Spitfire aircraft to be used with the Fleet Air Arm.1

A Spitfire Mk VB was modified in late 1941 by adding a tailhook.3 It was tested on the HMS Illustrious and concerns were expressed that the landing speed of the prototype was too great, however it was solved during the tests.3

Undercarriage

There were problems with the Seafire's narrow undercarriage.1 An a-frame arrestor hook was installed.2

Wings

The first model of Seafire to have folding wings was the Seafire F III.2,3 The wing tips were folder down, and then the wings folded up.3 This only added 125 lbs per plane.2 The fold was just inside the inner cannon and another fold on the wing tip.2 This allowed for easier storage in a carrier's hanger deck and made it easier for the plane to be moved around on deck.3

Prototype

During December 1941 Lt. Commander H. P. Bramwell made seven take offs and four catapult launches from the fleet carrier HMS Illustrious.2,3

The first prototype flew on January 7, 1942.1

The Seafire IIC first flew on May 28, 1943.2

Usage

Britain was the only user of the Seafire.1

20 FAA squadrons were equipped with the Seafire.1

First Use

The Seafire made its first operational debut in late 1942 during Operation Torch (invasion of North Africa).1,2,3 These were on the HMS Furious.3 Four squadrons were equipped with the Seafire Mk IICs.2 The 801 Naval Air Squadron (NAS) used the Seafire Mk IB.2 During 180 sorties the Seafires shot down three aircraft, damaged three in the air, and destroyed four on the ground.2 21 Seafires were lost, three being shot down, and the others because of the thick haze.2

Sicily

121 Seafires (15 Mk IICs, 106 L Mk IICs) were used in support of the invasion of Sicily.2 The were stationed on the escort carriers HMS Attacker, Battler, Hunter, and Stalker, and the fleet carriers HMS Formidable and Illustrious.2

Salerno

There were eight Seafire squadrons on the carriers HMS Formidable and Illustrious, and the escort carriers HMS Attacker, Battler, Hunter, and Stalker.3

During the covering operations, 42 Seafires were lost to accidents.2 Most of these were the inexperience of the pilots in taking off from Escort Carriers with a lack of wind.2

Seafire LR IIC

The Seafire LR IICs were first used by the No 4 Naval Fighter Wing in late 1943.2

British Pacific Fleet

Admiral Sir Bruce Fraser became commander in chief of the new British Pacific Fleet on November 22, 1944.2 The No 24 Naval Fighter Wing was equipped with Seafire F IIIs and Seafire L IIIs.2 The 887 and 894 Naval Air Squadron (NAS) performed most of the fleet defense with 40 Seafires.2 The fleet also had 12 Fireflies, 38 Hellcats, and 73 Corsairs.2

Korea

The HMS Triumph had Seafire F.47s which took part in the last combat of Seafires.3

Withdrawn from Service

In 1952 the Seafire was finally withdrawn from active duty.3
