A frigate is a type of warship. In different eras, the roles and capabilities of ships classified as frigates have varied somewhat.
USS Boone (FFG-28) was the twentieth ship in the United States Navy's Oliver Hazard Perry-class of guided missile frigates.
HMAS Nepal (G25/D14) was an N-class destroyer of the Royal Australian Navy (RAN). Launched in 1941 as Norseman, the ship suffered significant damage during an air raid on the John I. Thornycroft and Company shipyard, and during repairs was renamed to recognise Nepal's contribution to the British war effort. Although commissioned into the RAN in 1942, the ship remained the property of the Royal Navy.
The Royal New Zealand Navy is the maritime arm of the New Zealand Defence Force. The fleet currently consists of nine ships. The Navy had its origins in the Naval Defence Act 1913, and the subsequent purchase of the cruiser HMS Philomel, which by 1921 had been moored in Auckland as a training ship. A slow buildup occurred during the Interwar period, and then perhaps the infant Navy's finest hour occurred soon after the beginning of World War II when HMS Achilles fought alongside two other Royal Navy cruisers at the Battle of the River Plate in December 1939.
The Fiji-class cruisers were a class of eleven light cruisers of the Royal Navy that saw extensive service throughout the Second World War. Each ship of the class was named after a Crown colony or other constituent territory of the British Commonwealth and Empire. The class was also known as the Colony class, or Crown Colony class. Developed as more compact versions of the preceding Town-class cruisers, the last three were built to a slightly modified design and were sometimes also called the Ceylon class.
The River class was a class of 151 frigates launched between 1941 and 1944 for use as anti-submarine convoy escorts in the North Atlantic. The majority served with the Royal Navy and Royal Canadian Navy (RCN), with some serving in the other Allied navies: the Royal Australian Navy (RAN), the Free French Naval Forces, the Royal Netherlands Navy and, post-war, the South African Navy.
HMS Caroline is a decommissioned C-class light cruiser of the Royal Navy that saw combat service in the First World War and served as an administrative centre in the Second World War. Caroline was launched and commissioned in 1914. At the time of her decommissioning in 2011 she was the second-oldest ship in Royal Navy service, after HMS Victory. She served as a static headquarters and training ship for the Royal Naval Reserve, based in Alexandra Dock, Belfast, Northern Ireland, for the later stages of her career. She was converted into a museum ship. From October 2016 she underwent inspection and repairs to her hull at Harland and Wolff and opened to the public on 1 July 2017 at Alexandra Dock in the Titanic Quarter in Belfast.
Several ships of the Royal Navy have been named HMS Dragon.
HMS President is a retired Flower-class Q-ship that was launched in 1918. She was renamed HMS President in 1922 and moored permanently on the Thames as a Royal Navy Reserve drill ship. In 1982 she was sold to private owners and, having changed hands twice, served as a venue for conferences and functions as well as the offices for a number of media companies. She has been moved to Chatham on the Medway in Kent since 2016, but is due to return to the capital. She had the suffix "(1918)" added to her name in order to distinguish her from HMS President, the Royal Naval Reserve base in St Katharine Docks. She is one of the last three surviving Royal Navy warships of the First World War. She is also the sole representative of the first type of purpose built anti-submarine vessels, and is the ancestor of World War II convoy escort sloops, which evolved into modern anti-submarine frigates.
HMS Rotherham was an R-class destroyer of the British Royal Navy during the Second World War, named after Captain Edward Rotheram, who commanded HMS Royal Sovereign during at the Battle of Trafalgar in 1805. Rotherham was completed in 1942 and equipped as a flotilla leader, having slightly reduced armament to allow for the increased complement and working space required. Decommissioned in 1945, the ship was sold to India in 1948, serving as INS Rajput (D141) until 1976, when she was scrapped.
HMAS Diamantina (K377/F377/A266/GOR266), named after the Diamantina River in Queensland, is a River-class frigate that served the Royal Australian Navy (RAN). Constructed in the mid-1940s, Diamantina was active from 1945 until 1946, was placed in reserve, then was recommissioned as a survey ship from 1959 until 1980.
The Myanmar Navy is the naval warfare branch of the armed forces of Myanmar. With 24,000 personnel on duty, the navy operates more than 150 vessels. Prior to 1988, the navy was small, and its role in counter-insurgency operations was smaller than those of the army and the air force. The navy has since been expanded to take on a more active role in defense of Myanmar's territorial waters.
HMNZS Rotoiti (F625) was a Loch-class frigate of the Royal New Zealand Navy (RNZN), which had formerly served in the British Royal Navy as HMS Loch Katrine at the end of World War II.
HMS Loch Morlich was a Loch-class frigate that never saw service with the Royal Navy. Ordered during World War II, she saw service instead with the Royal Canadian Navy in the Battle of the Atlantic. She was named for Loch Morlich in Scotland. After the war she was returned to the Royal Navy and she was sold to the Royal New Zealand Navy and renamed Tutira.
HMS President is a "stone frigate", or shore establishment of the Royal Naval Reserve, based on the northern bank of the River Thames near Tower Bridge in Wapping and is in the London Borough of Tower Hamlets.
HMS Annan was a River-class frigate built for the Royal Navy but was transferred to the Royal Canadian Navy before commissioning. She served with the Royal Canadian Navy during the Second World War and saw action primarily as a convoy escort in the Battle of the Atlantic. She was returned to United Kingdom following the war and quickly sold to Denmark, who renamed the vessel Niels Ebbesen. She was primarily used as a training vessel until 1963 when she was broken up in Odense. She was named for the River Annan in Scotland in UK and Canadian service and Niels Ebbesen in Danish service.
HMS Alisma was a Flower-class corvette that served in the Royal Navy.
HMS Spey (K246) was a River-class frigate of the Royal Navy (RN) from 1942 to 1948, subsequently sold to the Egyptian Navy.
