A development of the Spitfire to provide a high-performance naval fighter

Please note: The Supermarine Seafire was a naval development of the most famous of all British aircraft, the Spitfire. The Seafire is covered in a many books and reference sources as a Spitfire development.  
 
Like the Spitfire, it deserves more space and detail than can be afforded on this web page so we urge further reference to the many books that describe its design and development. Jeffrey Quill’s autobiography Spitfire: A Test Pilot’s Story provides an excellent starting point. The Spitfire, itself, is presented separately.
=================================================================
 
The Supermarine Seafire was an urgent development of the Spitfire to generate a high performance carrier-based fighter aircraft. Somewhat compromised in service by an undercarriage that was not designed from the outset to handle the the rigours of carrier landings, the Seafire nevertheless gave valuable service throughout its operational life.
 
The Seafire Mk IB was a conversion of the land-based Spitfire VB with the conversions being carried out by Air Service Training (AST) and by Supermarine with the main modifications being the introduction of a retractable arrester hook and local fuselage strengthening.
 
The Seafire was produced in 8 marks with total production of 14 prototypes, 538 Spitfire conversions and 2,094 new-build aircraft giving a total of 2,646 aircraft (see the table below summarising production quantities from the various manufacturers involved).

The most important marks were (in numerical order):
  • The Mk I, and Mk II (total 542 aircraft converted from Spitfire VB and VC);
  • The Mk III with folding wings (Supermarine prototype and 1,263 new-build aircraft from Westland Aircraft and Cunliffe Owen)
  • The Griffon-powered Mk XV (6 prototypes and 434 production aircraft from Westland and Cunliffe Owen)
  • The Mk XVII with a cut down rear fuselage (prototype and 233 production aircraft, mainly from Westland).

The other production marks were the Griffon-powered F.45, F.46 and F.47.
 
The Seafire F Mk 47 was the final and most highly developed aircraft of the Spitfire / Seafire family and Test Pilot Jeffrey Quill is quoted as say that 'the overload weight of a Seafire F.47 was equivalent to a Spifire I carrying 32 airline passengers'.

Despite the operational limitations of a relatively short range and a somewhat fragile undercarriage, the Seafire saw operational service through to the end of the Second World War, operating with the Pacific Fleet off Japan right up to VJ Day.
