## 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 25 knots (46 km/h; 29 mph).[1][lower-alpha 1] 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]

## Construction and service history

The class was ordered from Faaborg Værft A/S on 3 December 2004, with the hull, superstructure and machinery constructed by Kockums at their yard in Karlskrona, Sweden.[2] Upon entering service, the Diana-class patrol vessels were used for fisheries protection, patrol and search and rescue.[1] The six vessels of the Diana class are assigned to the Royal Danish Navy's 2nd Squadron, which is tasked with international and combat operations.[3]
