A World War II-era American fighter jet, a single-engine, single-seater free-bearer lower-duty with a classic two-wheeled chassis pulled in flight. Since the P-40E version, the fighter jet was armed with six 12.7 mm (multi-calibre) Browning M2 machine guns and a 227 kg bomb or an additional fuel tank in its place. It was the first American combat aircraft to take part in World War II in the colours of British aviation as "Tomahawk I". In operations over the Western Desert, the P-40 was used as a fighter-bomber aircraft used in attack operations. A total of 13740 P-40 units of all versions were built.
