Royal Danish Navy


The Royal Danish Navy is the sea-based branch of the Danish Defence force. The RDN is mainly responsible for maritime defence and maintaining the sovereignty of Danish, Greenlandic and Faroese territorial waters. Other tasks include surveillance, search and rescue, icebreaking, oil spill recovery and prevention as well as contributions to international tasks and forces.
During the period 1509–1814, when Denmark was in a union with Norway, the Danish Navy was part of the Dano-Norwegian Navy. Until the copenhagenization of the navy in 1801, and again in 1807, the navy was a major strategic influence in the European geographical area, but since then its size and influence has drastically declined with a change in government policy. Despite this, the navy is now equipped with a number of large state-of-the-art vessels commissioned since the end of the Cold War. This can be explained by its strategic location as the NATO member controlling access to the Baltic.
Danish Navy ships carry the prefix KDM in Danish, but this is translated to HDMS in English. Denmark is one of several NATO member states whose navies do not deploy submarines.

History

The geographic layout of Denmark has a coastline to land area ratio of 1:5.9. By comparison, the figure for the Netherlands is 1:92.1 and for the United States, 1:493.2. Denmark therefore naturally has long-standing maritime traditions, dating back to the 9th century when the Vikings had small but well-organised fleets. They were often based in a small number of villages, usually with a common defence agreement; Viking ships, usually of the Knarr type, were light, and therefore easy to transport from village to village over land. With time, the defence pacts gave rise to larger, more offensive fleets which the Vikings used for plundering coastal areas. In the period after the Vikings, and up to the 15th century, the fleet consisted mainly of merchant vessels. Indeed, it is said that king Valdemar Sejr had more than 1,000 ships during the conquest of Estonia in 1219. Together they carried more than 30,000 soldiers with horses and supplies.
Records exist of a unified Danish navy from the late 14th century. Queen Margaret I, who had just founded the Kalmar Union ordered the building of a navy — mainly to defend the union against the Hanseatic League. Earlier the national fleet had consisted of vessels owned and operated by the nobility, but the country as such did not have a navy. The earlier monarchs therefore had to rely on conscription from the nobility, which was not always easy as the monarchy itself often had enemies within the nobility. Queen Margaret I gave instructions for a navy to be constituted and maintained under the control of the monarchy. The nobility still had to provide crews for these ships, though the core crew-members could be employed by the monarch. There were also education officers, mainly levied from the nobility.
In the 15th century, especially during the reign of King Hans, Danish trade expanded appreciably, increasing the need for the delivery of merchandise. As shipping was the ideal means of transport at the time, Danish maritime interests had to be further protected. King Hans is credited with establishing a joint Dano-Norwegian fleet in 1509, substantially increasing the number of professional crewmembers. They were mainly petty criminals, who had to choose between working in the king’s navy or imprisonment. They received basic training in seamanship and carpentry, enabling them to sail the ships. Responsibility for weaponry and combat was still in the hands of conscripted farmers. For these, the country was divided into a number of counties — known in Danish as skipæn, which would later serve as the Danish dioceses. It was also during this period that dedicated naval bases and shipyards were founded. They would build, maintain and fit out the king’s navy. The first record of a dedicated naval base is Bremerholmd in the year 1500.

Founding of the Danish navy

The founding of the Danish navy is often viewed in Denmark as taking place on 10 August 1510, when King Hans appointed his vassal Henrik Krummedige to become "chief captain and head of all our captains, men and servants whom we now have appointed and ordered to be at sea."
When King Frederick II was crowned in 1559, he immediately began expanding the navy. The number of bases, yards and vessels rose rapidly and substantial resources were used for new ship designs, weaponry, training and battle tactics. Sweden, which had become an independent country, dominated a large part of the Baltic Sea and threatened Danish merchant interests. In retaliation, Denmark closed the Øresund in 1568, laying the first seeds for the Scanian War, only eight years after the end of the second Nordic War, during which Denmark lost the now Swedish provinces of Skåne, Halland and Blekinge. During this period, further resources were allocated to the navy. Cort Adeler and Niels Juel led the Danish navy to a victory in the Battle of Køge Bay in 1677.
King Christian IV continued in his father's footsteps. In the beginning of the 17th century, he considerably expanded the naval workships. In Copenhagen, where the navy resided, he built a large number of homes for crewmembers and workshop craftsmen — the most famous being Nyboder which still stands in central Copenhagen.
General admiral lieutenant Ulrik Christian Gyldenløve was appointed supreme commander of the navy in 1701. He raised the status of the naval profession and established Søkadetakademie, the predecessor of the Royal Danish Naval Academy. In 1709, Peter Jansen Wessel joined the navy. He was later given the rank of admiral as a reward for his many victories – most famously at Marstrand and Dynekilden. He was later known as Tordenskjold.
In 1712, Tordenskjold succeeded in burning 80 Swedish naval cruisers, which played a large part in the outcome of the Great Nordic War. Since Scandinavia now was at peace, the navy focused its resources on other parts of the world, partaking in the colonisation of Africa and the Caribbean. A permanent naval presence of shifting strength was maintained in the Mediterranean Sea – protecting Danish-Norwegian interests in the region – mainly commerces against piracy. The Danish Mediterranean Squadron had numerous minor engagements with The Barbary States during the 1700s and 1800s. On several occasions these hostilities escalated to substantial actions. Some of the more notable can be said to be: the Mediterranean Squadron's bombardment of Algiers in 1770 under the command of rearadmiral Frederik Christian Kaas; the then captain, and future Privy Councillor, Steen Andersen Bille's action at Tripoli in 1797; and commander Hans Georg Garde in a joint Scandinavian expedition in 1844 – which effectively ended the Barbary states' attacks on Scandinavian merchants in the region. A pact of neutrality was made between Denmark and Sweden, providing a solid basis for commercial expansion.

Copenhagenization and rebuilding

The British, under pressure from the French in the Napoleonic Wars, became increasingly reluctant to allow Denmark to trade overseas as they believed First French Consul & General Bonaparte could benefit economically from Danish commerce. In 1801, they decided to attack a Danish line of defence, in the Battle of Copenhagen, under the command of Admiral Hyde Parker. The defence line, under the command of Olfert Fischer, put up a fierce resistance, but was subdued, with the loss of 3 ships sunk and 12 captured. Denmark was therefore forced to make an agreement with the British. In the following six years, Denmark managed to stay clear of the Napoleonic Wars, until the events leading to a second confrontation in 1807. Britain was afraid that the Danish fleet might fall under the control of Napoleon, perhaps tipping the balance in his favour. King Christian VII refused to hand over his navy to the British for safekeeping until the end of the war, and the British attacked. The city was bombarded and the king forced to surrender the fleet.
In 1814, Denmark and Norway were separated relatively peacefully, after more than 300 years together. At the same time, the Common Fleet was split into the Royal Danish Navy and the Royal Norwegian Navy.
The navy was slowly rebuilt, but it was nowhere near its former size. Faith was nevertheless placed in the navy, interests in Africa and the Caribbean still receiving considerable attention. In 1845, a two-year research expedition was launched on the corvette Galathea. In the Second Schleswig War, the navy was still relatively small and old-fashioned. Only a few steam vessels were at hand and these had a large impact on the war. As a result, it was considered necessary for the navy to be modernised. By the outbreak of World War I, the Danish navy was a very modern fleet, mainly equipped with armoured steam ships and only a very few sailing ships.

Interwar period and World War II

In the period between the two world wars, the Danish navy had low priority for the politicians, especially between 1929 and 1942 under Thorvald Stauning. During the first year of the German occupation, the navy assisted the occupying German forces with minesweeping, because of the political demand of keeping the infrastructure up and running. The tensions between the German soldiers and the Danish armed forces rose slowly and, on 29 August 1943, they managed to scuttle 32 of its larger ships, while Germany succeeded in seizing 14 of the larger and 50 of the smaller vessels. This was due to a secret order, given directly to the captains by word of mouth by commander of the navy, Vice Admiral A. H. Vedel "to try to flee to the nearest neutral or nazi-opposed port. If that was not possible, the ship should be scuttled at as deep a location as possible". The Germans later succeeded in raising and refitting 15 of the sunken ships. A number of vessels had been ordered to attempt to escape to Swedish waters, and 13 succeeded. The fleet flagship, Niels Juel, attempted to break out in the Battle of Isefjord but the crew was forced to beach and partly scuttle her. The score for the larger vessels was therefore: 32 vessels were sunk, 2 were in Greenland, 4 reached Sweden, 14 were captured by the Germans. As for the smaller vessels: 9 "patruljekuttere" reached Sweden, 50 others were captured by the Germans. By the autumn of 1944, these ships officially formed a Danish naval flotilla in exile. In September 1943, A. H. Vedel was fired by order of the prime minister Vilhelm Buhl because of his hostile actions towards the Germans.
In the post-war years, Denmark joined NATO in 1949. As a result, Denmark received large amounts of material and financing through the Marshall Plan. Furthermore, several ships were purchased from the British and a number of vessels were transferred from the now disarmed German navy.

Cold War

During the Cold War, the Danish navy was rebuilt and modernised, with the main assignment being to repel an invasion from the Warsaw Pact. Typical operations requiring training were minelaying and sting attacks with small but fast combat craft and missile torpedo boats and a self-sustaining mobile missile battery equipped with targeting and guidance, capable of firing Harpoon missiles. The Danish intelligence capabilities were also expanded and the Danish submarines trained for very shallow water operations, while a special naval force – the Danish Frogman Corps was created. The naval bases in Frederikshavn and Korsør plus the fortresses at Langeland and Stevns were created through NATO funds in the 1950s. In case of war all Danish combat vessels were assigned to NATO's Allied Forces Baltic Approaches's naval command NAVBALTAP.

Post-Cold War

Since the end of the Cold War, the navy has been in a transitional phase, from local defence to global operations, with fewer but larger vessels able to operate for long periods at sea. It has also been more self-sustaining. Under the defence agreement that initiated the process, several of the old "Cold War" frigates and minesweepers were decommissioned. The squadron structure prior to this defence agreement was as follows:
In the defence agreement of 2000–2004, further restructuring of the navy was ordered, as well as the decommissioning of several units. Furthermore, the only unit of Beskytteren class was donated to the Estonian Navy as. With the decommissioning of the torpedo boats, the 4th squadron was disbanded and the remnants were transferred to the 2nd squadron. Other units were also decommissioned. The squadron structure now looked like this:
On 1 January 2006, a major reorganisation was carried out as a part of the defence agreement of 2005–2009, when the former four squadrons were divided into two squadrons:

Naval Staff

The Naval Staff, led by a Rear Admiral, is directly responsible to the Danish Defence Command. Since 2014, it has been placed at Karup Air Base.

The squadrons

The Danish fleet today is divided into three squadrons:
The Naval Operational Logistic Support Structure, including the naval bases in Frederikshavn and Korsør as well as several naval stations.

Naval bases

The naval bases' task is to provide logistic support for the ships and vessels, through the OPLOGs. This includes configuration, maintaining and repairing the units. Furthermore, similar support is provided to civilian agencies and allied units like the United Nations
The support is mainly provided within the geographical areas of the naval bases. For Naval Base Korsør that is Zealand, Funen, Bornholm as well as the surrounding waters. For Naval Base Frederikshavn it is Jutland, Greenland and the Faroe Islands. Moreover, general support is provided for units participating in international operations in peacetime, as well as all units in crisis and wartime.

Naval stations

The navy maintains a number of naval stations. These are smaller stations with limited support functions. The best known is the publicly accessible Naval Station Holmen in Copenhagen. There are also naval stations located in Kongsøre

Danish Task Group

Danish Task Group is a unit tasked with commanding, educating and training maritime forces in peace, crisis and war. It is a mobile unit that is experienced in orchestrating exercises, organising insertions and commanding naval, aerial and land-based units. Danish Task Group was created to expand Denmark's level of competency and quality of material, by participating in international maritime operations. As such Danish Task Group has been commanding combined maritime forces in both exercises and operations and -151 ) a number of times.

The naval school structure

Runs three main schools, with five special schools:

Vessels

The Danish navy currently operates:
as well as a number of rigid-hulled inflatable boats, boats etc.
The navy ship programs are generally of the "newer but fewer" type. Many of the vessels are of more recent dates or under replacement, i.e. the corvettes of the Niels Juel class have been replaced with three new for 2nd Squadron and the Barsø class has been replaced with 6 Diana-class small patrol crafts. Finally all three Agdlek class vessels have been replaced with the new vessels.
In addition, the Royal Danish Navy and the German Navy are in cooperation in the "Ark Project". This agreement made the Ark Project responsible for the strategic sealift of Danish and German armed forces where the full-time charter of three roll-on-roll-off cargo and troop ships are ready for deployments. Furthermore, these ships are also kept available for the use of the other European NATO countries.

Air service

Early years

The Royal Danish Navy has operated aircraft since 1912 either as a functional part of the navy or as flights conducted by the Royal Danish Air Force. Aviation pioneer Robert Svendsen purchased the first aircraft, a Henry Farman, and gave it to the navy who subsequently named it Glenten. Later the same year, a private funding effort made it possible to purchase two Donnet-Leveque flying boats named Maagen and Ternen.
At the outbreak of World War One the navy had two operational flying boats and five trained pilots making it possible to make daily reconnaissance flights over the Sound, monitoring German mine-laying activities.
From 1914 to 1917, the Orlogsværftet produced eight OV-flying boats and in 1915 and 1916 two naval flying stations were established in Copenhagen and Nyborg, mainly focusing on the two international seaways Øresund and Storebælt.
After the war the Danish production of aircraft was stopped due to several crashes and an international surplus of warplanes. Following British advice, five Avro 504s were purchased for training purposes, and based in Ringsted between the two important straits.

Fighter aircraft

In 1925 three land-based fighter aircraft were purchased to be based in Ringsted. A modified version of the Hawker Woodcock, the Hawker Danecock, was initially delivered from the UK while a following series of 12 aircraft were license-built by the Orlogsværft.
In 1928 the naval air service procured six Heinkel HE 8 floatplanes, with another 16 to be license-built by the Orlogsværft. As Germany were not allowed to produce military aircraft, the planes were labelled as mail planes, but they could easily be refitted with dual machine guns, radio equipment and a capacity for eight bombs.
The Heinkel had an unexpected arctic employment in the early 1930s when a dispute over East Greenland caused the first deployment of aircraft, along with three naval ships, in Greenland. Following settlement of the dispute between Denmark and Norway the Heinkels were used in the efforts to map the frontiers of the island.
In 1933 two Hawker Nimrods were acquired to keep pace with the rapidly evolving technology of naval aircraft. A further ten aircraft were to be produced under licence at the Orlogsværft. The new aircraft made the air base in Ringsted inadequate and the naval air service was moved to the Avnø peninsula at southern Zealand.

Attack aircraft

In 1932 the navy purchased its first offensive capacity, two Hawker Horsley torpedo bombers with an option to produce a following series on the Orlogsværft. After four years of testing and practice, the naval air service had agreed to expand the offensive capacities with the Horsley, but at this time funding from the Danish government had been cut and no further torpedo bombers were acquired.
In the late 1930s the government changed plans and increased the budget for military purchases following the German expansions in central Europe. In 1938, 12 Fairey P.4/34s were to be produced at Orlogsværftet, along with 12 Italian Macchi C.200 fighters. None of these were produced before the German invasion of Denmark on April 9, 1940.

Helicopters

Helicopters are deployed from the air force's 723rd squadron to Danish naval ships. When initiated in 1962, the naval helicopters consisted of a flight of Alouette helicopters of RDAF squadron 722.
Primarily for use on the in operations in Greenland and Faroe Islands, but also on in international operations and off Greenland as well as participating in exercises.
The independent unit was established in 1977 as "Søværnets Flyvetjeneste" operating and Westland Lynx helicopters. On December 6, 2012, the Danish Air Force officially ordered nine MH-60R Seahawk helicopters, with all to be delivered by 2018, following a competition on the procurement involving the NH90, AgustaWestlands AW159 Wildcat and the AW101 along with Sikorsky's other bid H-92 Superhawk.
