01/31/2010. Remarks by Johan Visschedijk: "Upgrading the H81A-2 P-40B, or Tomahawk IIA, with improved self-sealing fuel tanks, revised internal equipment and a further pair of wing-mounted guns resulted in the P-40C, 193 examples of which completed for the USAAC, and a further 930 similar machines were built as the H81A-3 for the RAF, entering service as the Tomahawk IIB.

The Tomahawk IIB carried an armament of six 0.303 in (7.7 mm) machine guns (two in the nose and four in the wings), and whereas the Tomahawk IIA had British radio, the IIB had US equipment. The Tomahawk IIBs were shipped to both the UK and to Takoradi, West Africa, and were operated RAF, RAAF and South African AF Squadrons.

The RAF did not take delivery of all 930 Hawk 81A-3s ordered for 100 were transferred to the Chinese AF, and the last 49 machines were shipped direct to the USSR. Several hundred aircraft were held at maintenance units in the UK, but when the German invasion failed to materialize 146 were reshipped to the USSR. The pictured aircraft was operated by the 126 IAP (Fighter Regiment) of the Soviet AF."
