The Mk VIII was the follow-up of the Mk VII without the pressurized cabin and differed little from it’s Mk VII sibling. All Mk VIII Spitfires were built solely by Supermarine. A few early production models had extended wingtips, but the majority had the standard version. There are three sub-variants; the LF Mk VIII for low altitude, the F Mk VIII for medium altitude and HF Mk VIII for high altitude. Each was powered respectively by the Merlin 66, Merlin 63 and Merlin 70 engines.
The Mk VIII served almost exclusively overseas in the Mediterranean, with both the Desert Air Force and the USAAF, in the Pacific with the Royal Australian Air Force and with the RAF in the China-Burma-India theater. After the Mk IX and Mk V, the Mk VIII was the third most numerous operational variant with 1,658 examples.
