The first navalized Spitfires, basically Mk Vb airframes with an added arrestor hook,
were used mostly for evaluation and training purposes.
Seafire Mk Ib: this first version of the Seafire had a strengthened Spitfire Mk Vb airframe,
with an arrestor hook, slinging points and naval radios. It was powered by a Merlin 45 (1470 HP) or
Merlin 46 (1415 HP) engine.
166 such conversions were made.
Seafire Mk IIc: fitted with Spitfire 'c' wings, these planes had catapult spools.
The Mk II could carry a 250 kg (500 lb) bomb. 262 such planes were built.
Both Mk I and Mk II Seafires were delivered to the Royal Navy in June 1942.
Seafire Mk IIc
Rolls-Royce Merlin 45 liquid-cooled V12
2x 20mm cannons and 4x 7.7 mm (0.303 cal) Browning machine guns
To improve low-altitude performance, the Seafire L IIc was powered by a boosted Merlin 32
engine, producing 1640 HP, and had a four-bladed propeller.
30 of these planes were converted to the Seafire LR IIc, a photo reconnaissance version.
The Seafire Mk III was the first Seafire to have folding wings.
The Seafire L Mk IIIc was fitted with the 1585 HP Merlin 55M engine, had a centerline rack
for a 250 kg (500 lb) bomb and could launch rockets. 1218 Seafire Mk IIIs were built, including
more than 120 Seafire FR III photo reconnaissance conversions.
The Seafire F XV was powered by the 1815 HP Rolls-Royce Griffon VI, and was the last
After World War 2, the Seafire development went on with the Seafire 17,
Seafire 45 (based on the Spitfire Mk 21), Seafire Mk 46 (based on the Spitfire Mk 22)
and the final Seafire FR 47, whose production came to a stop in March 1949.
Stof's notes about this plane in iMOL's WarBirds
The opinions expressed below are only my own, and nothing more...
Being nothing than a slightly heavier Spitfire Mk Vb, the Mk II has the same strong and weak points,
with of course the bonus of being available aboard carriers.
