The Absalon class are frigates of the Royal Danish Navy,[2][3][4] commissioned in 2005. The two ships in the class may be described as a hybrid between a frigate and military transport ship with multiple role capabilities,[5] with the capacity to be transformed from a combat ship with the firepower of a traditional frigate to a hospital ship within a day.[6]

Design

The class is based on a frigate-like design, but built with an internal multipurpose deck (flex deck) and a stern vehicle ramp. The ships can serve as command platforms for a staff of 75 persons (naval or joint staff) with a containerized command and control centre, transport and base of operations for a company-sized landing force of some 200 soldiers with vehicles. Alternatively, the flex deck can be used for mine-laying operations with a capacity of some 300 mines, or be fitted out for mine-clearing operations and launch and recover mine detecting and clearing equipment via a retractable gantry crane, adjacent to the stern vehicle ramp, which also is used for launching and recovering the fast landing craft. Furthermore, the flex deck can support a containerized hospital or simply transport a number of ISO standard containers or some 55 vehicles, including up to seven main battle tanks. The ships can carry two landing craft, personnel (LCPs) (Storebro SB90E), two rigid hull inflatable boats and two AW-101 helicopters.

The ships have been designed by a joint team from The Royal Danish Navy (RDN), the Danish Defence Acquisition and Logistics Organization (DALO) and a group of contractors, primarily Odense Maritime Technology (OMT) to the Royal Danish Navy's requirements for a multi-mission frigate-like ship with an emphasis on flexibility.

The ships are built to the naval standards of Det Norske Veritas (DNV GL), an international certification body and classification society, heavily utilizing STANAG.

The design is built with the aim of a large margin for growth over life-cycle, to a relatively low cost of ownership, with open architecture for ease of upgrades, with a high degree of automation allowing smaller crews, and utilizing StanFlex modules that can be shared across several ship classes in service with the Royal Danish Navy.

The hulls were built in highly competitive commercial shipyards using the latest development in the industries shipbuilding technology and cost-effective production procedures and processes. The outfitting and integration of sensor, communication and weapons systems was primarily carried out "in-house" by the RDN and DALO.

The standard weapons of the Absalon class can be supplemented through the use of StanFlex mission modules.[7] A special weapons deck (nicknamed the 'Bathtub') is designed with five StanFlex module slots.[7] Because of the Bathtub's position, only missile-firing weapons modules can be installed.[7]

History

The ships were named after two brothers, Esbern Snare and archbishop Absalon, who led the naval campaigns in the 12th century against the Wends, a group of pagan Slavs in northern Germany.

Production started at Odense Steel Shipyard on 30 April 2003,[1] with the lead ship Absalon laid down on 28 November of that year.[1] Esbern Snare followed on 24 March 2004; they were both launched later that year.[1] They were delivered on 19 October 2004 and 17 April 2005 respectively, and commissioned on 10 January 2005 and 17 June 2005.[1] At this point they had the StanFlex modules installed, but would have to wait until 2007 for full operational capability,[1] with the installation of the 35mm CIWS, Mk32 torpedo launchers and Seagnat/SRBOC decoy systems.

Among other upgrades the two ships of the Absalon class were fitted with the newer Terma Scanter 6002 to replace the Scanter 2001 in 2020.

For political reasons, the ships were originally launched as "Flexible support ships" to avoid antagonising Russia after the end of the cold war.[8] On the 16th of October 2020, both ships were reclassed as anti-submarine warfare-frigates. Both ships will be upgraded with towed array sonars in addition to the existing, hull-mounted sonar. The Sikorsky SH-60 Seahawk helicopters will be equipped with dipping sonars, sonobuoys and torpedoes. This upgrade is expected to complete in 2026.[9]
