At a very early stage, the Curtiss P-40 attracted the attention of foreign air forces. On May 10, 1939, the French government ordered 140 export versions of the P-40 for the Armee de l"Air. These aircraft were designated Hawk 81-A1 by the manufacturer. The Hawk 81-A1s were identical to the US P-40 except that they had French instruments and equipment and were equipped with reverse-movement "French-fashion" throttles.
The first of the French-ordered H81-A1s flew on June 6, 1940, and a few were actually completed with French markings. However, before any of their H81-A1s could be delivered, France had surrendered. Britain agreed to take over the entirety of the French order, and gave the H81-A1 the name Tomahawk I in RAF service. RAF serials were AH741/AH840 and AH841/AH880.
In September of 1940, the USAAC agreed to defer deliveries of their P-40s so that the Tomahawk Is could be supplied to Britain as soon as possible. The first Tomahawk Is reached England in September of 1940. The two 0.5-inch machine guns in the nose were retained, but they were supplemented by four wing-mounted 0.303-inch Browning machine guns in place of the 7.5-mm FN-Brownings originally specified by the French. Such was the urgency of their delivery to Britain that many of the 140 machines still had French instruments and bore cockpit lettering in French when they arrived.
This was in the days before Lend-Lease, and so the aircraft had only RAF serial numbers and markings, and were not issued USAAC serials or designations. The Curtiss construction numbers were 14446/14545 and 14091/14130. RAF serials were AH741/AH880. At least three (AH774, AH793, and AH840) were retained in Canada but still retaining their RAF serials.
