The Diana class, also known as the Minor Standard Craft Mk II, are a class of six patrol boats in service with the Royal Danish Navy. Built by Faaborg Værft A/S, the ships displace 280 tonnes (280 long tons) and have a maximum speed of 18 knots (33 km/h; 21 mph) knots. The class was intended to replace the aging Barsø class of patrol boats. The lead ship of the class, HDMS Diana, entered Danish service in 2007. The Diana-class vessels were initially tasked with fisheries protection, patrol and search and rescue but are currently tasked with international and combat operations.
Design and description
The Diana class, also known as the Minor Standard Craft Mk II, are a series of patrol vessels constructed of glass reinforced plastic. They measure 43.0 metres (141 ft 1 in) long with a beam of 8.2 m (26 ft 11 in) and a draught of 2.0 m (6 ft 7 in). They are powered by two MTU 16V396 TB94 diesel engines turning two shafts with controllable pitch propellers creating 2,100 kilowatts (2,816 bhp). This gives the patrol vessels a maximum speed of 18 knots (33 km/h; 21 mph).[1][a] The ships mount two 12.7-millimetre (0.50 in) machine guns and have a complement of 9, with accommodation for 15 total.[1][2] The Diana-class patrol vessels each have space for a StanFlex container, allowing for quick mission re-configuration.[1]
