127 mm gun
The gun is an old American twin-barrel gun able to engage targets in the air, on surface and on land (shore bombardment). It got the Danish type designation M/60. By lift from the ammunition handling compartment the shell and the cartridge (propelling charge) were brought up to the gun where they were placed manually on the rammer cradle, joined and rammed into the chamber of the gun. Then the breach was closed, and the gun was ready to fire. The guns could be laid remotely from one of the fire control centers or locally, where laying to the side was limited due to the heavy weight (36 tons) of the gun. Similarly the gun could be fired from the fire control or locally from the left side of each gun.

The gun had 2 aiming systems - a binocular sight for the side and height layer and a target designation sight for the gunner. The crew of each gun was 12. After firing, the recoil was stopped by hydraulic brakes on either gun, the cartridge was expelled onto the deck via a slide aft of each gun, and the gun pipe was vented to remove any gasses from the gunpowder. Each gun could fire up to 15 shells per minute. After 1 minute of firing the barrel had to be cooled before firing could be resumed. The velocity of the shell was 795 m/sec and at an elevation of 40⁰ the max. range was app. 16 km.
The windlass is an electric winch fitted with two messenger wheels to pull home the anchor chain, and capstans for pulling home hawsers or wires. When the anchor was to be dropped, the windlass was de-clutched. Two anchors of each 1.6 tons and 220 m of chain are placed in the bow. Each chain weighs 6.7 tons. A similar anchor is placed in the stern.
Sea Sparrow magazine
In addition to the 8 air defense missiles in the launchers on the aft deck 9 missiles are stored in a magazine from where a crane can lift each one directly out to the aft deck and onto the launcher. In the magazine is placed a Sea Sparrow missile type 7H and a training missile. The missiles are 3.66 m long, have a diameter of 20.3 cm and a weight of 226.8 kg.
The infirmary consists of an infirmary and a sick bay. The infirmary was used for medical checks and minor operations. The 4 bunks of the sick bay of which 2 were mounted on gimbals were used to isolate sailors with contagious diseases from the rest of the crew.
Normally a medic handled routine matters, but on long voyages a doctor was embarked. In action the Officers' Wardroom could serve as an infirmary.
Second-in-command was the substitute of the Captain and had the rank of Commander. He and the First Technical Officer were the only officers having a cabin of their own on the main deck. However, they had to share their bath and toilet. All other officers and petty officers were accommodated in one or two-bunk cabins on the Quarter deck or the Platform deck.
First Technical Officer's cabin
He had the rank of Commander and was heading the Technical Division responsible for operation and maintenance of the propulsion machinery of the Frigate and e.g. the auxiliary engines producing the electricity necessary for the weapons system, the radio station, light etc.
The casing is the lower part of the room around the aft funnel. From here there is access to the stern gear room and here you will find an emergency compressor run by a 4-stroke diesel engine compressing the air up to 24 bar. In an emergency it is able to provide enough air for starting the diesel engines.
The Quartermaster was the officer acting as personnel administrator for the sailors. He had their files, made the watch plans and administrated their applications for leave. He also arranged for new personnel to report to the Frigate as replacement for old hands. Furthermore he was responsible for the station bill (ships organization) stating where each single person should report in case of e.g. battle, damage control, fire, salvage or cleaning up.
In the Frigate's galley 2-3 cooks, 1 baker and 2-3 assistants prepared the food for the entire complement - originally 202 persons, but after the re-fitting 191 in case of reinforced alert. All onboard were served the same food, tasted and approved by the Officer on Watch before serving.
Food for the Captain, the officers and petty officers was fetched by their wardroom and mess stewards and brought to their respective pantries.
Sea Sparrow launcher
The launcher contained up to 8 Sea Sparrow missiles for shooting down enemy aircraft and missiles. Another 9 missiles were placed in a magazine. The target is illuminated by one of the two large fire control radars, and after launch the missile is guided to the target by a radar beam.

The explosive charge is 15 kg and the speed is Mach 2.5 corresponding to 2,990 km/h. Max. range is 16 km. The missile is 3.66 m long, has a diameter of 20,3 cm and a weight of 226.8 kg.
Fanfare T Mk.6
This system was developed in the US to protect ships against homing torpedoes. A small noise-maker was towed after the Frigate in a 200 m long cable. Inside the noise-maker was a small electrical engine making a spindle strike on the inner side of a cylinder. That produced a noise corresponding to the noise of the propeller of a ship, and thereby it was able to attract enemy torpedoes instead of hitting the ship.
Torpedo type T1T (placed on the jetty)
The torpedo is a German 53.3 cm torpedo of which the Navy bought a large number after the Second World War. In the 1960s the torpedo was modified for wire guidance. In the torpedo and in the launching tube on board the Frigate a wire spool is mounted and a millimeter thin wire is paid out to ensure that the wire is lying completely still during the run of the torpedo. Via the wire the operator could turn the torpedo to hit the selected target. The torpedo is a war torpedo - the front transport eye only has to be replaced by a war pistol. The torpedo has a length of 7.19 m, weighs 1,520 kg and has an explosive charge of 300 kg. At 30 knots it has a range of 12 km, and at 40 knots of 7 km. Normally, it was fired at a distance of 8-9 km and set at a speed of 30 knots.
Torpedo type TP 612
The torpedo is a Swedish wire-guided torpedo which the Navy started using in 1971 as a replacement of the older Type T1T torpedo. The torpedo did not use compressed air in the engine for combustion, but highly concentrated peroxide. This demanded special precautions for maintenance and transport, but it meant that the torpedo did not leave a trace of telling air bubbles when fired. The TP612 was surprisingly accurate, too, as its side track error was less than 0.3⁰ and its speed varied less than 0.3%. Wire-guidance from the TORCI in the Ops-room towards a distant radar target gave a higher hit probability than achieved by the type T1T. It had a range of 18.5 km at a speed of 45 knots and 24 km at 30 knots. It weighed 1,755 kg and carried an explosive charge of 235 kg. The torpedo shown here is a war torpedo with installed war pistol. Bending of one of the wings will make the torpedo detonate.
In 1973 the Frigate was armed with 4 torpedo tubes in double mounts hydraulically turned 15⁰ over the side of the frigate and launched by air from a launching kettle or by a 600 g gunpowder cartridge. Normal firing was by air via an electric impulse from the TORCI system in the Ops-room. Alternatively the torpedo could be launched "locally" by pressing a handle on the tube. Both torpedo type 1T1 and type TP 612 could be launched. The torpedoes were running at a set depth and were controlled from the TORCI fire control via a thin wire which was spooled off from the torpedo as well as the torpedo tube, making the wire lie completely still in the water.
The Officer's wardroom was their sitting and dining room. It was possible to seat 30 persons. Normally only 22 officers were serving onboard, but often guests were embarked. Under reinforced alert the manning was increased to 26 officers. Wardroom stewards fetched the food in the galley and arranged it in the pantry. The wardroom was used for briefings, too, and for representation at port calls etc. In war it could serve as emergency infirmary.
Petty Officers Mess
The mess acted as a sitting and dining room for 20 petty officers. Mess stewards fetched the food in the galley, arranged it in the pantry next to the galley and served it in the mess. All the petty officers who have served in Peder Skram are represented by a small silver plate with their name, profession and year of service on the bulkhead of the mess.
Here the 130 sailors of the crew messed in three shifts. One shift was on duty, one was working and one was off duty. Eating took place in groups of 40 persons corresponding to a shift. At reinforced alert the crew was increased to 145. Cold food was served from the forward and warm food from the aft hatch.
