Initially called the Bisley Mk.I, the Bristol Blenheim Mk.V was conceived as a close support aircraft, with four machines guns in a solid nose. The first prototype (AD657) also had more powerful engines than the Mk.IV, additional armour and an improved dorsal turret. A second prototype (AD661) replaced the solid nose with glazing, to undertake a bombing role.
Only the bomber version was accepted for production, but although an improvement on the Blenheim Mk.IV, was still vulnerable to modern fighters. Most of the 940 produced served in North Africa of the Far East, with many relegated to training or target towing once its shortcomings became apparent.
