The Bangor class was designed as a small minesweeper that could be easily built in large numbers by civilian shipyards; as steam turbines were difficult to manufacture, the ships were designed to accept a wide variety of engines. Bihar displaced 673 long tons (684 t) at standard load and 860 long tons (870 t) at deep load. The ship had an overall length of 189 feet (57.6 m), a beam of 28 feet 6 inches (8.7 m) and a draught of 10 feet 6 inches (3.2 m).[1] The ship's complement consisted of 60 officers and ratings.[2]
The VTE-powered Bangors were armed with a QF 12-pounder (7.62 cm) anti-aircraft gun and a single QF 2-pounder (4 cm) AA gun or a quadruple mount for the Vickers .50 machine gun. In some ships the 2-pounder was replaced a single or twin 20 mm Oerlikon AA gun, while most ships were fitted with four additional single Oerlikon mounts over the course of the war.[3] For escort work, their minesweeping gear could be exchanged for around 40 depth charges.[2]
