The Royal Navy Submarine Service is the submarine element of the Royal Navy. It is sometimes known as the Silent Service, as the submarines are generally required to operate undetected.^[1]

The service operates seven fleet submarines (SSNs), of the Trafalgar and Astute classes, and four ballistic missile submarines (SSBN), of the Vanguard class. All of these submarines are nuclear powered. The service also owns the LR5 Submarine Rescue System.

The Royal Navy's use of submarines began in 1901, and for many years of the late 20th century was associated with HMS Dolphin in Hampshire. Flag Officer Submarines moved from Dolphin to the Northwood Headquarters in 1978. In the early 21st century Flag Officer Submarines lost his solely submarine role and is now Commander Operations on the staff of Commander-in-Chief Fleet. The Submarine School is now at HMS Raleigh at Torpoint in Cornwall.

History

HMS Holland 1, the first-ever submarine to be commissioned by the Royal Navy. She can still be seen at the Royal Navy Submarine Museum, Gosport.

At the beginning of the 20th century, the idea of submarine warfare was considered by senior personnel in the Admiralty to be "Underhand, unfair and damned un-English"^[2] (Admiral Sir Arthur Wilson VC, 1901). However, those in favour of experimenting with submarine technology eventually won the argument, and the Royal Navy launched its first submarine, Holland 1, in 1901.

The Submarine Service proved its worth in World War I, where it was awarded five of the Royal Navy's 14 Victoria Crosses of the war, the first to Lieutenant Norman Holbrook, Commanding Officer of HMS B11.

On 30 August 1939 Rear Admiral Submarines, Rear Admiral B.C. Watson, moved his headquarters from Gosport to Aberdour, Scotland, though the administrative staff remained at Gosport. The RN started the Second World War with 60 submarines.^[3] On 31 August 1939 Second Submarine Flotilla at Dundee (Forth and ten submarines) and Sixth Submarine Flotilla at Blyth (HMS Titania and six submarines) were part of the Home Fleet. HMS Clyde and HMS Severn, part of the Seventh Submarine Flotilla, were at Freetown under the orders of the Commander-in-Chief, South Atlantic; ten submarines were in the Mediterranean along with the depot ship HMS Maidstone (First Submarine Flotilla); and the submarine depot ship HMS Medway and the Fourth Submarine Flotilla were under the Commander-in-Chief, China, split between Singapore and Hong Kong.^[4] Roskill writes that the effective naval strength of the British Empire on the outbreak of war included 38 submarines.

During the war the major operating arenas were the Norwegian waters; the Mediterranean where a flotilla of submarines fought a successful battle against the Axis replenishment route to North Africa; and the Far East where Royal Navy submarines disrupted Japanese shipping operating in the Malacca Straits.^[5]

In January 1940, Vice-Admiral Max Horton was made commander of all home-seas-based submarines, even though he was far more senior in rank than the Flag Officer Submarines had traditionally been, because of a new Admiralty regulation that the Flag Officer Submarines had to be an officer who had served aboard submarines in the Great War. Horton's biographer, Rear Admiral William S. Chalmers, cites the opinion that this regulation was forced through for the sole purpose of ensuring that Horton was on a very short list of qualifiers for this post, almost ensuring his rapid transfer to Aberdour, so great was the desire of some within the Admiralty to have Horton revitalize the submarine arm.

In the Mediterranean (during the Siege of Malta), British U-class submarines began operations against Italy as early as June 1940. Larger submarines also began operations, but after 50% losses per mission, they were withdrawn. U-class submarines operated from the Manoel Island Base known as HMS Talbot. Unfortunately no bomb-proof pens were available as the building project had been scrapped before the war, owing to cost-cutting policies. The new force was named the Tenth Submarine Flotilla and was placed under Flag Officer Submarines, Admiral Max Horton, who appointed Commander George Simpson to command the unit.^[6] Administratively, the Tenth Flotilla operated under the First Submarine Flotilla at Alexandria, itself under the admiral commanding in the Mediterranean, Cunningham. In reality, Cunningham gave Simpson and his unit a free hand. Until U-class vessels could be made available in numbers, British T-class submarines were used. They had successes, but suffered heavy losses when they began operations on 20 September 1940. Owing to the shortage of torpedoes, enemy ships could not be attacked unless the target in question was a warship, tanker or other "significant vessel".^[7][8] The flotilla's performance of the fleet was mixed at first. They sank 37,000 long tons (38,000 t) of Italian shipping; half by one vessel, the submarine HMS Truant. It accounted for one Italian submarine, nine merchant vessels and one Motor Torpedo Boat (MTB). The loss of nine submarines and their trained crews and commanders was serious. Most of the losses were to mines.^[9] On 14 January 1941, U-class submarines arrived, and the submarine offensive began in earnest.^[10]

One of the most famous Mediterranean submarines was HMS Upholder, commanded for its entire career by Lieutenant-Commander Malcolm Wanklyn. Wanklyn received a Victoria Cross for attacking a well-defended convoy on 25 May 1941 and sinking an Italian liner, the Conte Rosso. In her 16 month operational career in the Mediterranean, before she was sunk in April 1942, Upholder carried out 24 patrols and sank around 119,000 tons of Axis ships – 3 U-boats, a destroyer, 15 transport ships with possibly a cruiser and another destroyer also sunk.

On 8 September 1944, C-in-C Mediterranean ordered that the submarine base at Maddalena be closed, and that Tenth Flotilla be disestablished and the submarines be incorporated into the First Submarine Flotilla at Malta.^[11]

The submarine force was cut back after the end of the war. The first British nuclear-powered submarine, HMS Dreadnought (S101) was launched in 1960 based around a U.S.-built nuclear reactor. This was complemented by the Valiant class from 1966, which used a new British-built Rolls-Royce PWR1 reactor. The UK's strategic nuclear deterrent was transferred to the Royal Navy from the Royal Air Force at midnight on 30 Jun 1968, ie 1st July. The Resolution class ballistic missile submarines (SSBNs) were introduced to carry out this role under the Polaris programme from 1968. These carried US-built UGM-27 Polaris A-3 missiles and were later replaced by the Vanguard class submarines and the Trident missile system from 1994.

In 1978 the Flag Officer Submarines who was also COMSUBEASTLANT, part of SACLANT, moved from HMS Dolphin at Gosport to the Northwood Headquarters.^[12]

HMS Conqueror made history in 1982 during the Falklands War when she became the first nuclear-powered submarine to sink a surface ship, the ARA General Belgrano.

In May 1991 Oberon class submarines HMS Opossum and her sister HMS Otus returned to the submarine base HMS Dolphin in Gosport from patrol in the Persian Gulf flying Jolly Rogers (see below), the only indication that they had been involved in alleged SAS and SBS reconnaissance operations.^[13]

In 1999 HMS Splendid participated in the Kosovo Conflict and became the first Royal Navy submarine to fire a cruise missile in anger.^[14]

After Operation Veritas, the attack on Al-Qaeda and Taliban forces following the 9/11 attacks in the United States, it emerged that HMS Trafalgar was the first Royal Navy submarine to launch Tomahawk cruise missiles against Afghanistan,.^[15] HMS Triumph was also involved in the initial strikes.^[16] On 16 April 2003 it was reported that HMS Turbulent, the first Royal Navy vessel to return home from the war against Iraq, had launched fourteen Tomahawk cruise missiles.^[17]

In 2011, HMS Triumph and Turbulent participated in Operation Ellamy, they launched Tomahawk cruise missiles at targets in Libya, firing the first shots of the operation.^[18]

The Jolly Roger and the Submarine Service

Admiral of the Fleet Sir Arthur Wilson VC, the Controller of the Royal Navy, summed up the opinion of many in the Admiralty at the time when he said in 1901 "[Submarines are] underhand, unfair, and damned un-English. ... treat all submarines as pirates in wartime ... and hang all crews."^[19][20] In response, Lieutenant Commander (later Admiral Sir) Max Horton first flew the Jolly Roger on return to port after sinking the German cruiser SMS Hela and the destroyer SMS S-116 in 1914 while in command of the E class submarine HMS E9.^[21]

In World War II it became common practice for the submarines of the Royal Navy to fly the Jolly Roger on completion of a successful combat mission where some action had taken place, but as an indicator of bravado and stealth rather than of lawlessness. For example in 1982 returning from the Falklands conflict HMS Conqueror flew the Jolly Roger depicting one dagger for the SBS deployment to South Georgia and one torpedo for her sinking of the Argentinian Cruiser Belgrano. The Jolly Roger is now the emblem of the Royal Navy Submarine Service.^[22]

Perisher

The "Dolphins" badge, issued to all British submariners on completion of training. It is worn on the upper left breast, just above any medal ribbons.

'Perisher' (as the Submarine Command Course is better known) is a 24-week course all officers must take prior to serving as an Executive Officer on board a Royal Navy Submarine. It has been run twice a year since 1917, usually starting on 2 July and 14 November each year. It is widely regarded as one of the toughest command courses in the world, with a historical failure rate of 25%.^[23]

If at any point during the training a candidate is withdrawn from training he will be nominated for boat transfer and kept occupied until the transfer. His bag is packed for him and he is notified of the failure when the boat arrives. On departure he is presented with a bottle of whisky. A failure on Perisher means that the unsuccessful candidate is not permitted to return to sea as a member of the Submarine Service (although they are still allowed to wear the dolphin badge). He is, however, permitted to remain in the Royal Navy, moving into the surface fleet.

In more recent years, the United States Navy has sent some of its own submariner officers to undergo the 'Perisher', in order to foster and maintain closer links with the Royal Navy.

Since the Royal Navy no longer operates diesel-electric submarines, in 1995 the Royal Netherlands Navy has taken over the Perisher course for these boats from the British, and annually host a course that is attended by candidate submarine commanders from multiple navies around the world.^[24]

Traditions

The Submarine Service has many traditions that are not found in the surface fleet. These include slang unique to submariners (such as referring to the torpedo storage compartment as the Bomb Shop and the diesel engine room as the Donk Shop^[25]), a special communications code known as the Dolphin Code and the entitlement of a sailor to wear Dolphins upon entering the service. Which were only awarded after completion of training and qualification in ships systems - on board first submarine posting (Part III training).

Problems with alcohol use while on shore leave were highlighted in the inquest following the murder on board Astute in April 2011. As of February 2013 there had been over 300 disciplinary incidents in the past three years on the RN's 13 submarines, of which 42 were substance abuse-related.^[26]

Active submarines

The decline in attack submarine numbers since 1970 and the concentration on nuclear-powered vessels.

The Submarine Service consists of two classes of Fleet submarines and one class of Ballistic Missile submarines.

Fleet submarines

HMS Astute, a nuclear-powered fleet submarine

There are six fleet submarines on active duty - four Trafalgar class submarines and two Astute class submarine. They are all nuclear submarines and are classified as SSNs.^[27]

These submarines are armed with the Spearfish torpedo for anti-submarine and anti-surface warfare. Some are also armed with Tomahawk cruise missiles for attacking targets on land. This capability was used by HMS Trafalgar against the Taliban in 2001 during Operation Veritas. The Fleet submarines are also capable of surveillance and reconnaissance missions.^[28] Fleet submarines are sometimes referred to as attack or hunter-killer vessels.

Ballistic submarines

HMS Vanguard, a ballistic missile submarine

The four ballistic missile submarines (SSBN) of the Royal Navy are all of the Vanguard class. They were all built by Vickers Shipbuilding and Engineering Ltd, now BAE Systems Submarine Solutions. The SSBN flotilla or bomber 'fleet' tends to be almost a separate entity, for example it rarely uses pennant numbers preferring to use hull numbers, thus Vanguard 05, Victorious 06, Vigilant 07 and Vengeance 08.

The four Vanguard class boats are responsible for the United Kingdom's nuclear deterrent, and use the Trident missile system. Each boat can carry up to 16 Trident II D5 Missiles, each of which may carry up to 12 nuclear warheads. It is UK Government policy to limit the actual number of warheads carried to 48 per boat. There has been at least one SSBN on patrol at all times for around 40 years and since April 1969, the Royal Navy's SSBNs have not missed a single day on patrol.^[29]

LR5 Submarine Rescue System

The Royal Navy operated the LR5 Submarine Rescue System, designed for retrieving sailors from stranded submarines. Capable of rescuing up to 16 sailors at a time, the system was deployed to the wreck site of the sunken submarine Kursk. The system was replaced in 2004 with the NATO Submarine Rescue System which remains based in the UK.

Decommissioning nuclear submarines

Nuclear submarines awaiting decommissioning have been laid-up at Rosyth and Devonport. In 2014 the MOD announced a plan to decommission 7 of the submarines awaiting disposal, in a project expected to take 12 years. A site for the intermediate-level nuclear waste produced is expected to be identified by 2016.^[30]

Future submarines

A total force of seven Astute class fleet submarines is planned. As of June 2014, the first two boats are in commission and in service, the third is launched and due to be commissioned by the end of 2015, while boats four to six are in various stages of construction. Boat number seven was confirmed in the October 2010 Strategic Defence and Security Review and long-lead items have been ordered.^[31] The Astute class submarine is the largest nuclear fleet submarine ever to serve with the Royal Navy, nearly 30% larger than its predecessors. Its powerplant is the Rolls Royce PWR2 reactor, developed for the Vanguard class SSBN. The submarines armament consists of up to 38 Spearfish torpedoes and Tomahawk block IV land-attack missiles.

A Successor to the UK Trident system is in its early stages, with 'Main Gate' decisions to be made in 2016. The programme will seek to replace the current Vanguard class ballistic missile submarines starting sometime during the mid-late 2020s.
