The Bulwark, an Albion-class assault ship, has a Goalkeeper close-in weapon system and a range of 8,000 miles. In 2015, the ship took part in Operation Weald, which rescued Libyan migrants trying to cross the Mediterranean.
Shortly after this helicopter carrier was commissioned in 1998, it aided a humanitarian mission in the aftermath of Hurricane Mitch. The Ocean can carry a number of different helicopters, as well as landing vessels that deposit troops on shore.
An Astute-class submarine, the Artful is nuclear-powered and can circumnavigate the globe without resurfacing. It's also the first in its class to feature the Common Combat System, a high-tech sonar data processing system that helps its crew plan an attack. It will become a regular feature on Royal Navy submarines in the future.
Commissioned in 2007, this patrol vessel serves a number of roles, from troop insertion to search and rescue. It also can refuel an in-flight helicopter when it's unable to land. In 2015, the Clyde helped rescue passengers of the Le Boreal cruise ship, after a fire broke out in the engine room.
Commissioned in 1993, this vessel serves a key role in the fleet. All four of the fleet's ballistic missile submarines hold the "letters of last resort," handwritten notes from the current British prime minister outlining what to do if a nuclear strike destroys the government.
This Type 23 frigate has aided in missions to battle narcotics, human trafficking and arms smuggling. In 2015, the Lancaster became the first ship in the fleet to be outfitted with a Wildcat attack helicopter.
In 2011, the Type 23 frigate was involved in a battle off the coast of Libya, destroying a gun battery. The ship also assisted NATO in illuminating positions held by Muammar Gaddafi, the deposed leader of the nation. Prince William spent five weeks serving on the Iron Duke in 2008.
This Type 23 frigate comes armed with antiair, -ship and -submarine missiles and has a helicopter landing pad. It helped evacuate British citizens trapped in Lebanon during that country's conflict with Israel in 2006.
In 2016, this Scimitar-class fast patrol boat was involved in an incident with a Spanish vessel, when it attempted to pass in the path of a nuclear submarine from the United States' fleet. The Sabre fired warning flares at the ship.
The Shoreham was commissioned in 2002 and is the Royal Navy's newest mine countermeasures vessel, an entirely different class than the Ledbury. This class is smaller than its predecessor and features a similar sonar system, making it useful in clearing mines.
The smallest vessel in the fleet is also one of the oldest. Commissioned in 1983, the Gleaner is a coastal surveyor boat, collecting data on the seabed and depth of water. The ship's prefix is HMSML, or Her Majesty's Survey Motor Launch.
The Scott is a one-of-a-kind ship in the Royal Navy's fleet. As an ocean survey vessel, it's used to scan the seabed. After the 2004 Indian Ocean earthquake, the Scott studied the seabed and found that the topography near the epicenter had changed.
Known as "The Black Duke," the Monmouth is the only active ship to fly a black flag, due to the actions of its namesake in 1685. The Duke of Monmouth led a failed rebellion against King James II, which led to his execution and his coat of arms being blacked out.
This Trafalgar-class submarine took part in Operation Veritas, the British contribution to the invasion of Afghanistan after the 9/11 attacks. In 2011, the Triumph was involved in an attack on Libyan targets as part of Operation Ellamy.
The Queen Elizabeth is the largest warship the Royal Navy has ever built. Expected to be commissioned in late 2017, the carrier can hold up to 40 aircraft and 1,600 people. It also features the Phalanx Close-In Weapons System as part of its armament, which acts as its antiaircraft and antimissile defense.
Currently in development is the Type 26 frigate, which will become the "workhorse" of the fleet. Set to replace the Type 23, this ship will have the nation's most advanced weaponry, including a vertical missile silo.
