Design and description
The Halcyon class designed as a replacement for the preceding Template:Sclass2 and varied in size and propulsion. Halcyon displaced Template:Convert at standard load and Template:Convert at deep load. The ship had an overall length of Template:Convert, a beam of Template:Convert and a draught of Template:Convert.[1]
She was powered by two vertical compound-expansion steam engines, each driving one shaft, using steam provided by two Admiralty three-drum boilers. The engines produced a total of Template:Convert and gave a maximum speed of Template:Convert. Halcyon carried a maximum of Template:Convert of fuel oil that gave her a range of Template:Convert at Template:Convert.[2] The ship's complement consisted of 80 officers and ratings.[3]
Halcyon was armed with two QF 4-inch (10.2 cm) guns; the forward gun was in a high-angle mount while the aft gun was in a low-angle mount. She was also equipped with eight Template:Convert machine guns. Later in her career, the rear 4-inch gun mount was removed as were most of the .303 machine guns, one quadruple mount for Vickers .50 machine guns was added as were up to four single or twin mounts for 20 mm Oerlikon anti-aircraft guns. For escort work, her minesweeping gear could be exchanged for around 40 depth charges.[4]
