The Vaedderen is a DanishThetis class multi-role frigate used for fishery protection, surveillance, air-sea rescue, anti-pollution and ice reconnaissance. The armament consists of one Otobreda 76 mm Super Rapid main gun, one or two 20 mm guns from Oerlikon, and depth charge throwers. The Super Rapid gun has a rate of fire of 120 rounds per minute and a range of 16 km. The fire control system is the CelsiusTech 9LV 200 Mk 3. A FLIR Systems Inc AN/AAQ-22 SAFIRE thermal imaging system is used for surveillance. All weapon and equipment systems are connected through the frigates' command, control and communications system. The frigate has a landing deck with a landing spot for a single helicopter. Helicopter support arrangements include a glide path indicator (GPI) and a flight refuelling system. The hangar is equipped for helicopter maintenance and has capacity to hold a Lynxhelicopter without having to fold the helicopter tail.
The Vaedderen has a double-skinned hull up to two metres above the water-line. The hull is divided by ten bulkheads into watertight compartments such that the ship is able to sustain hull damage up to eight metres in length without dangerous instability problems. For ship propulsion, one engine-room and the gear-room can be water-filled at the same time, and the frigates will still be able to proceed.
The Vaedderen is powered by three MAN B&W V28/32 diesel engines with a combined power of 9000 kW providing a top speed of 10 knots. Research Vaedderen
