   The Iver Huitfeldt class frigates of the Danish navy are based on the same hulls as Absalon class support ships, designed for command and support roles. This feature allowed to considerably reduce design and construction costs of these new frigates, and maintain commonality. The main role of the Iver Huitfeldt class is air defense. Three ships of this class were built. The lead ship was commissioned with the Royal Danish Navy in 2012.

   The Iver Huitfeldt class frigates have a somewhat unusual layout and look a bit bulky for this class of ships. Nevertheless they pack a formidable punch. Most anti-air warfare sensors and equipment are similar to the German Sachsen class frigates and Dutch De Zeven Provincien class destroyers. Though, the Iver Huitfeldt is a less capable warship, than those mentioned above.

   Mounted round the top of the superstructure are the four antennae of the Thales advanced phased-array air/surface radar. It provides 360 target detection, tracking and engagement. Up to 32 missiles can be guided in flight simultaneously, including 16 missiles in terminal stage. Such capability is extremely important while defending against saturated missile attacks. There is also the Thales SMART-L radar for long-range aerial surveillance. It can detect and track ballistic missiles at a range of more than 400 km. It is capable of tracking 1 500 targets simultaneously and provides early warning. It is considered that radar combination of the Iver Huitfeldt class is more capable than Aegis radar combination of the Spanish Alvaro de Bazan class anti-air warfare frigates.

   The primary surface-to-air missile armament is carried in the Mk.41 32-cell Vertical-Launch System (VLS). It packs Standard SM-2 missiles (range 150 km), or SM-6, as well as RIM-162 Evolved Sea Sparrow missiles (range 50 km) in designated cells. Up to of 32 SM-2 and 24 to 48 ESSM missiles are carried by the warship.

   The Iver Huitfeldt class frigates have a modular mission payload system. The same system is used one the Absalon class support ships. This frigate has slots for six modules. So it can accommodate either additional ESSM air defense missiles or Harpoon anti-ship missiles. Also these frigates have potential to be equipped with Tomahawk cruise missiles.

   This frigate is also armed with two OTO Melara 76-mm guns. Also there is a single 35-mm Oerlikon Millennium Close-In Weapon System (CIWS). The last mentioned is an advanced weapon system. It has a rate of fire of a whooping 1 000 rpm and uses special air-burst ammunition to destroy incoming missiles. It is planned that in the future the two 76-mm guns will be replaced by a more potent 127-mm gun and additional 35-mm CIWS.

   The Danish frigate has an integral hull-mounted sonar for submarine detection. Anti-submarine weapons include two twin 324-mm launchers for EUROTRP MU90 lightweight torpedoes. This frigate has a hangar and can accommodate NFH 90, Westland Lynx Mk.90B, or similar helicopter, which provides additional anti-submarine warfare capability. Recently Danish Navy ordered Sikorsky MH-60R Seahawk anti-submarine helicopters.

   The Iver Huitfeldt class has a diesel-only propulsions system. It is powered by four MTU 20V M70 diesel engines, developing a combined output of 44 000 shp. The power is delivered to 2 shafts. Also there is a single bow thruster. These Danish frigates are very fuel efficient. At lower speeds it is capable of traveling 16 700 km (9 000 nautical miles). It is enough to travel from Denmark to the United States and back, while there will still be fuel left in the tanks.

   This frigate is operated by 101 sailor. However there is lodging for 165 men.

   Even though the Iver Huitfeldt class packs a formidable punch, it is slightlty inferior to the German Sachsen class frigates. It lacks a third layer missile defense and carries less torpedoes. The Danish frigate has got only hull mounted sonar, but no tower array sonar for submarine detection. Also the German frigate carries two helicopters. Furthermore the Danish frigate has inferior diesel-only propulsion system, which looses in terms of performance to modern Combined Diesel or Gas (CODOG) propulsions.
