The main weapon of the Frigate was the 8 homing HARPOON missiles to be launched against hostile ships. The missile is 4.83 m long with a diameter of 34 cm and a range of 92 km. The radar search antenna is placed in the front and behind there is an auto pilot with a radar height finder. Behind this is a turbine jet engine and a rocket engine which is released upon sending the missile up to a height of 400 m and giving it a speed of 1,000 km/h. The missile will then fly the ordered course at a height of app. 5 meter. When the missile is approaching its target, its search radar is activated and the first major radar echo is attacked.
The missile has an explosive charge of 100 kg and a delayed percussion fuse making the detonation take place inside the target. All orders to the missile and the actual launching takes place from a special panel in the Ops-room. After launching the Frigate has no control of the missile.
Everybody onboard ate the same food, but the wardroom and messes could decorate and arrange the food according to own taste and finances. After having fetched the food in the galley the Captain's steward arranged the meals when Captain had visitors or dined alone.
This was the Commanding Officer's sitting room and office as well as bedroom and bath. His rank was a Commander senior grade, and in a safe under his desk he kept the classified plans describing the expected activities of the Frigate during general alert and in case of war. Here, too, he had the key to the launching panel of the HARPOON missiles.
This was the room where welcomed his visitors and dealt with matters concerning the crew, and here he received the daily report of the test meal having been approved. He was not a member of the Officers Wardroom, so he dined here if he was not invited to the Wardroom.
When the Frigate had embarked VIPs they were accommodated here. The most frequent guest was the Commander of the Frigate Squadron, who used the Frigate as his command platform, when acting as NATO's local maritime force commander of the joint Danish West German invasion defense during The Cold War. Like other VIPs he dined with the Captain or in the Officers' Wardroom. Also the Rear Admiral being the commander of the Naval Operational Command used this cabin when he was aboard.
This station was the link to shore and other ships. When the Frigate was command platform signals were received, re-written and transmitted to ships and aircraft in order to coordinate the various complicated operations. To ensure the best possible radio conditions Morse key and many different frequencies were used. The classified signals were both in- and decoded. That required a close contact to the Captain and a high security clearance.
The radio station was manned around the clock with a minimum of two operators and a signalman.
Fire Control Center Bravo/Charlie
The control centers got their data from two unmanned fire directors fitted with both radar and low light TV. Each center could calculate the ballistics for targets at sea, in the air and on shore.
Fire control Center B/C.
When a target designation had arrived from the Ops-room the two fire control centers could lock on the target based on ballistic data for the 127 mm guns as well as the 40mm guns corrected for the movements of the Frigate. The guns could be laid remotely and divided between the three fire control centers of which Alpha was placed close to the Ops-room. After spotting of the shell splashes the fire control center could immediately make the necessary corrections and fire a new salvo. Due to the extended automation only three persons were needed in each center.
20 mm machine guns
At the end of the 1980s the Frigate was armed with four 20 mm machine guns type M/42. The guns were laid by hand and had limited effect, but they were part of the close defense to be used against aircraft and fast motor boats. Their grenades weighed 121 g., and they could fire 175 grenades per minute.

40 mm machine guns
The four 40 mm machineguns in the anti-aircraft mount (LvSa, model 48) primarily acted as close air defense against hostile aircraft and missiles. The guns were loaded with packs of four cartridges and could fire app. 300 rounds/min. The gunnery crew consisted of 5-6 men of which 2 were loading the gun. Max. range was 12,600 m. The mount could be turned sideways at a speed of 90⁰ pr. second, and elevated 45⁰ per second.

The guns could be laid from the artillery center or a gyro control, but they could also be controlled from a fire director at the left side of the mount. As a last option, if all the other sight systems should go down, they could be laid by hand by an elevation handle on the left side and a side laying handle in the right side. The elevation layer could fire the gun locally. The gun was placed in a glass fiber cupola instead of protected by a shield.
Sea Sparrow Center
The center actually consisted of two fire control centers from where two hostile airplanes or missiles could be engaged simultaneously. After the Ops-room has designated the target one of the two fire control centers took over the illumination with its fire control radar.

When the radar's very concentrated beam had locked on the target and the computers indicated a hit range of app. 16 km the first missile was launched. The Sea Sparrow centers had a manning of five.
