Design

The OPV is approximately 81 metres (265 ft 9 in) long with a beam of about 12.5 metres (41 ft 0 in) and is understood to displace at least 1,500 tons.^[1] It is powered by two diesel engines driving two propellers. The OPV is capable of operating a helicopter from its approximately 17.5-metre (57 ft)-long flight deck and has a single hangar. A stern ramp is fitted for a rigid-hulled inflatable boat.^{[citation needed]} The armament comprises manually operated 57-millimetre (2.2 in) twin guns in Type 66 or 76 gun mount on the forecastle as well as two manually-operated heavy machine guns atop the hangar deck. Sensors include two Furuno navigation radars.

The Inlay will supplement the two remaining Danish-built Osprey-class OPVs in service.^{[citation needed]}
