This is a list of Active Royal Navy weapon systems.

Guns

4.5-inch Mark 8 naval gun

Main article: 4.5-inch Mark 8 naval gun

The 4.5-inch (114 mm) Mark 8 gun can be found on all the

War in Iraq
. The gun can fire up to 24 high explosive shells per minute, each weighing more than 40 kilograms (88 lb), at targets more than 12 miles (19 km) away – this can be extended to nearly 18 miles (29 km) if special extended-range shells are used.

The main purpose of the gun is naval gunfire support – artillery bombardment of shore targets. In this role the gun is capable of firing the equivalent of a six-gun shore battery. It can still be used as an anti-ship weapon.[1]

30 mm DS-30B Mk 1/DS30M Mark 2 naval gun

Main article: 30mm DS30M Mark 2 Automated Small Calibre Gun

The 30 mm DS-30B Mk 1 and DS30M Mark 2 are 30-millimetre (1.2 in) automated naval gun systems designed to defend ships from fast inshore attack craft armed with short-range weaponry. The DS30M Mark 2 system consists of a

offshore patrol vessels (OPVs) (Mk2s), Hunt-class mine countermeasures vessels (Mk1s), Sandown-class minehunter (Mk1) and several Royal Fleet Auxiliary (RFA) ships (Bay, Tide and Wave classes) all reported to be carrying Mk1s when they have weapons packages added. The system is capable of being deployed on the aircraft carriers HMS Queen Elizabeth and HMS Prince of Wales, but as of 2021 had not been fitted.[2][3][4]

Oerlikon 20 mm cannon

Main article: Oerlikon 20 mm cannon

The Oerlikon 20 mm (0.79 in) cannon can be found on the

landing platform docks, the Batch 1 River-class OPVs, the primary casualty receiving ship RFA Argus, and the multi-role replenishment ship Fort Victoria.[4]

Browning .50-calibre (12.7 mm) heavy machine gun

Main article: M2 Browning

The Browning .50-calibre heavy machine gun can be found fitted to ships, the first of which was HMS Atherstone in 2014,[5] and in 2021 it was reported that HMS Lancaster had also been fitted with them.[6]

7.62 mm miniguns

Main article:

All Royal Navy ships carried miniguns for close in defence.[7][8] But the system was scheduled to be retired from service in 2023 and replaced with Browning .50 caliber heavy machine guns.[9]

7.62 mm General Purpose Machine Gun (GPMG)

Main article: FN MAG

GPMGs are used for close in defence.[7][8]

Close-in weapon systems

Phalanx 20 mm

Main article: Phalanx CIWS

The Phalanx

C-RAM system.[10]

Phalanx is now the only CIWS fitted to Royal Navy ships following the decommissioning of HMS Invincible, HMS Illustrious and the Type 22 frigates which were equipped with Goalkeeper. The last active Goalkeeper system was removed from HMS Bulwark when she entered extended readiness in 2016.

Torpedoes

Spearfish torpedo

Main article: Spearfish torpedo

The Spearfish torpedo is the Royal Navy's heavyweight torpedo, weighing nearly 2 metric tons (2.0 long tons; 2.2 short tons), which is carried by both the attack submarines and ballistic missile submarines. It has a range of more than 30 mi (48 km) with a speed in excess of 92 miles per hour (148 km/h) and can be used either against other submarines or ships of any size. It carries a 300 kg (660 lb) explosive charge and is guided either by its in-built sonar or via a copper-cadmium wire.[11]

The Spearfish is undergoing a major upgrade program which will provide sophisticated advances in its homing, warheads, tactical and fueling systems, as well an upgraded guidance link.[12]

Sting Ray torpedo

Main article:
Sting Ray torpedo

The Sting Ray torpedo is the Royal Navy's lightweight torpedo which is designed to be carried by the

Lynx Wildcat. It has a range of around 5 mi (8.0 km) with a speed of more than 52 mph (84 km/h) and is designed to be used predominantly against submarines. It carries a 45 kg (99 lb) explosive charge which is powerful enough to punch through the double hulls of modern submarines.[13]
It is also integrated on board the Type 23 frigates, deployed by two twin torpedo launchers.

Depth charges

The Mk11 Depth Charge is a depth charge used by Lynx Wildcat or Merlin Mk2 helicopters to attack enemy submarines.[14]

Mine disposal system

Seafox

Main article: Seafox drone

The Seafox Mine Disposal System is an

fibre optic
cables. Once a mine has been identified, an expendable autonomous or remote guided unit is guided to the target and detonates a shaped charge to destroy the mine. Four independent reversible motors and a hover thruster provide high manoeuvrability, allowing for exact placement prior to charge detonation. The Seafox has been used by the Royal Navy clearing coastal waters in both Iraq and Libya conflicts.

Surface-to-air missiles

Sea Ceptor

Main article:
Sea Ceptor

The Sea Ceptor missile is currently being integrated [when?] into the Type 23 frigates, as a replacement to the Sea Wolf missile. It has a maximum range over 25 kilometres (16 mi) and can reach Mach 3. The manufacturer states it has a "wide target set", including the capability to engage small naval vessels, which would give the missile a limited surface-to-surface role. A Royal Navy officer of the Type 23 frigate HMS Westminster stated: "Westminster managed to explore the real potential of the system during her training and to say it is a real game changer is an understatement. Unlike its predecessor, the system is capable of defending ships other than Westminster herself. Whether it's engaging multiple air threats or fast incoming attack craft, Sea Ceptor represents a massive capability upgrade for the Type 23 frigate."[15]

Sea Viper

Main article:

The Sea Viper is the main weapon of the Type 45 destroyers. As part of PAAMS, it can defend an entire naval task group against aerial threats up to 70 mi (110 km) away.

Internationally, the Sea Viper system is known as

Aster 30 (75 mi, 121 km) missiles, which are highly manoeuvrable and capable of speeds over Mach 4.[16]

Anti-ship missiles

Naval Strike Missile

Main article: Naval Strike Missile

In November 2022, UK Secretary of State for Defence, Ben Wallace, confirmed that Norway's Naval Strike Missile would be purchased to equip a total of eleven of the Royal Navy's Type 23 frigates and Type 45 destroyers on an interim basis.[17][18] Beginning in late 2023, the Naval Strike Missile (NSM) began being fit to a total of 11 Type 23 frigates and Type 45 destroyers in a 2×4 canister configuration to replace the Harpoon Block 1C anti-ship missile, which was formally retired at the end of 2023.[19] The missile also has the capability to attack land targets.[20]

The permanent replacement for Harpoon will be the

FC/ASW (Future Cruise/Anti Ship Weapon), first announced in 2016, it will fly at hypersonic speed and will equip the new Type 26 frigates from 2028.[21][22] In October 2021 this was put on hold.[23][24] Then it was announced in November that the introduction of these weapons may be delayed until the 2030s.[25]

Martlet

Main article:
Lightweight Multirole Missile

The Martlet is a lightweight air-to-surface and surface-to-surface missile under development by Thales Air Defence for the United Kingdom. As of 2021, Martlet entered initial service on the Fleet Air Arm's AgustaWestland AW159 Wildcat in the air-to-surface mode with up to twenty Martlet missiles envisaged for deployment on a single Wildcat helicopter. The missile is intended to counter light fast attack boats.[26] Full operating capability is anticipated in 2025.[27]

The Martlet has also been tested in the surface-to-surface mode on the Type 23 frigate, using a launcher mounted on the side of the 30 mm cannon, as a relatively inexpensive missile to use against small craft and unmanned aerial vehicles.

Sea Venom

Main article: Sea Venom (missile)

The Sea Venom is a helicopter-launched lightweight anti-ship missile developed by MBDA to replace the Sea Skua. Sea Venom missiles were reported deployed with Royal Navy Wildcat helicopters operating as part of the Royal Navy's carrier strike group in 2021.[28] The missile weighs 110 kg (240 lb) and has a warhead of 30 kg (66 lb). However, operating challenges were reported in 2023 as "ongoing" and full operating capability for Sea Venom was delayed until 2026.[29][30] It is optimized to attack fast inshore attack craft (FIAC), however it can also damage targets up to corvette size.[31]

Land attack missiles

A Trident II Submarine Launched Intercontinental Ballistic Missile

Tomahawk missile

Main article: Tomahawk (missile)

The Tomahawk missile, also known as TLAM (Tomahawk Land Attack Cruise Missile), allows the Navy's submarines to strike at targets on land accurately. The missile has been in use with the Royal Navy since the late 1990s and has been used in the

Iraq. It is fired from a boat's torpedo tubes
. Once it reaches the surface, a booster rocket ignites to propel the missile skywards. The Tomahawk then heads for its target at 550 mph (890 km/h), delivering a 1,000 lb (450 kg) explosive warhead.

The Tomahawk IV is the latest version of the missile. It has a longer range than its predecessors and can be directed at a new target in-flight, and can also beam back images of the battlefield. In British service it is fitted to all Trafalgar and Astute-class submarines.[32] It is currently planned to be[when?] phased out of service in the United States Navy, with no more weapons to be produced after 2015, meaning that it may no longer be an option for the Royal Navy from around the end of the decade.[33] The UK last bought 65 Tomahawk Land Attack Missiles in July 2014.[34]

Trident II D5 ballistic missile

Main article: UGM-133 Trident II

The Trident nuclear missile is

nuclear deterrent. Carried only by the four Vanguard-class submarines, the missiles travel up to 7,000 mi (11,000 km) at over 13,000 mph (21,000 km/h). Each Vanguard boat can carry up to sixteen missiles, and each missile can deliver up to eight warheads. Each variable yield warhead can have a yield up to 100 kt.[35]
