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. Khyber displaced 656 long tons (667t) at standard load and 820 long tons (830t) at deep load. The ship had an overall length of 174 feet (53.0m), a beam of 28feet 6inches (8.7m) and a draught of 10feet 3inches (3.1m).[1] The ship's complement consisted of 60 officers and ratings.[2]
She was powered by two Parsons geared steam turbines, each driving one shaft, using steam provided by two Admiralty three-drum boilers. The engines produced a total of 2,000 shaft horsepower (1,500kW) and gave a maximum speed of 16 knots (30km/h; 18mph). Khyber carried a maximum of 160 long tons (163t) of fuel oil that gave her a range of 2,800 nautical miles (5,200km; 3,200mi) at 10 knots (19km/h; 12mph).[3]
The turbine-powered Bangors were armed with a 12-pounder 3-inch (76mm)anti-aircraft gun and a single QF 2-pounder (4cm) AA 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, her minesweeping gear could be exchanged for around 40 depth charges.[2]
