A navy, naval force, or maritime force is the branch of a nation's armed forces principally designated for naval and amphibious warfare; namely, lake-borne, riverine, littoral, or ocean-borne combat operations and related functions. It includes anything conducted by surface ships, amphibious ships, submarines, and seaborne aviation, as well as ancillary support, communications, training, and other fields. The strategic offensive role of a navy is projection of force into areas beyond a country's shores. The strategic defensive purpose of a navy is to frustrate seaborne projection-of-force by enemies. The strategic task of the navy also may incorporate nuclear deterrence by use of submarine-launched ballistic missiles. Naval operations can be broadly divided between riverine and littoral applications, open-ocean applications, and something in between, although these distinctions are more about strategic scope than tactical or operational division.
Telegraphy is the long-distance transmission of messages where the sender uses symbolic codes, known to the recipient, rather than a physical exchange of an object bearing the message. Thus flag semaphore is a method of telegraphy, whereas pigeon post is not. Ancient signalling systems, although sometimes quite extensive and sophisticated as in China, were generally not capable of transmitting arbitrary text messages. Possible messages were fixed and predetermined and such systems are thus not true telegraphs.
U-boats were naval submarines operated by Germany, particularly in the First and Second World Wars. Although at times they were efficient fleet weapons against enemy naval warships, they were most effectively used in an economic-warfare role and enforcing a naval blockade against enemy shipping. The primary targets of the U-boat campaigns in both wars were the merchant convoys bringing supplies from Canada and other parts of the British Empire, and from the United States, to the United Kingdom and to the Soviet Union and the Allied territories in the Mediterranean. German submarines also targeted Brazilian merchant ships during both World Wars and, twice over, precipitated Brazil's decision to give up its neutral stance and declare war on Germany.
The Fleet Air Arm (FAA) is one of the five fighting arms of the Royal Navy and is responsible for the delivery of naval air power both from land and at sea. The Fleet Air Arm operates the F-35 Lightning II for maritime strike and the AW159 Wildcat and AW101 Merlin for commando and anti-submarine warfare.
The Battle of the Atlantic, the longest continuous military campaign in World War II, ran from 1939 to the defeat of Nazi Germany in 1945, covering a major part of the naval history of World War II. At its core was the Allied naval blockade of Germany, announced the day after the declaration of war, and Germany's subsequent counter-blockade. The campaign peaked from mid-1940 through to the end of 1943.
Takeo Yoshikawa was a Japanese spy in Hawaii before the attack on Pearl Harbor on December 7, 1941.
HMS Conqueror was a British Churchill-class nuclear-powered fleet submarine which served in the Royal Navy from 1971 to 1990. She was the third submarine of her class, following the earlier Churchill and Courageous, that were all designed to face the Soviet threat at sea. She was built by Cammell Laird at Birkenhead.
The history of the Royal Canadian Navy goes back to 1910, when the naval force was created as the Naval Service of Canada and renamed a year later by King George V. The Royal Canadian Navy (RCN) is one of the three environmental commands of the Canadian Forces. Over the course of its history, the RCN has played a role in the First World War, contributed significantly to the Battle of the Atlantic during the Second World War, and was a part of NATO's force buildup during the Cold War. In 1968, the RCN was amalgamated with the Canadian Army and the Royal Canadian Air Force to form what is today the unified Canadian Armed Forces. The naval force was known as Maritime Command until 2011, when the environmental command was renamed as the Royal Canadian Navy.
Thomas Crisp VC, DSC, RNR was an English sailor and posthumous recipient of the Victoria Cross. Crisp, in civilian life a commercial fisherman operating from Lowestoft in Suffolk, earned his award after being killed during the defence of his vessel, the armed naval smack Nelson, in the North Sea against an attack from a German submarine in 1917.
HMS Graph was a German Type VIIC U-boat that the British Royal Navy captured during World War II. Commissioned as U-570 in Nazi Germany's Kriegsmarine in mid-1941, she was attacked and captured on her first patrol.
HMS Seal was one of six Grampus-class mine-laying submarines of the Royal Navy. She served in the Second World War and was captured by the Kriegsmarine and taken into German service as UB, one of several captured subs. She was the only submarine the Germans captured at sea during World War II. Her capture allowed the Germans to correct a critical fault in their U-boat torpedoes.
HMS Affray was a British Amphion-class submarine. It was the last Royal Navy submarine to be lost at sea, on 16 April 1951, with the loss of 75 lives.
The Royal Navy Submarine Service is one of the five fighting arms of the Royal Navy. It is sometimes known as the Silent Service, as submarines are generally required to operate undetected.
The Submarine Escape Training Facility (SETF), also known as the Submarine Escape and Rescue Centre (SERC), is a facility used by submariners of the Royal Australian Navy (RAN) to train in the techniques needed to escape from a submarine in trouble.
On the Beach is a 1959 American post-apocalyptic science fiction drama film from United Artists starring Gregory Peck, Ava Gardner, Fred Astaire, and Anthony Perkins. Produced and directed by Stanley Kramer, it is based on Nevil Shute's 1957 novel On the Beach depicting the aftermath of a nuclear war. Unlike the novel, no one is assigned blame for starting the war, which attributes global annihilation to fear compounded by accident or misjudgment.
Speech-generating devices (SGDs), also known as voice output communication aids, are electronic augmentative and alternative communication (AAC) systems used to supplement or replace speech or writing for individuals with severe speech impairments, enabling them to verbally communicate. SGDs are important for people who have limited means of interacting verbally, as they allow individuals to become active participants in communication interactions. They are particularly helpful for patients with amyotrophic lateral sclerosis (ALS) but recently have been used for children with predicted speech deficiencies.
Vice-Admiral Sir Arthur Richard Hezlet, nicknamed Baldy Hezlet, was a decorated Royal Navy submariner. He became the Royal Navy's youngest captain at the time – aged 36 – and its youngest admiral, aged 45. In retirement he became a military historian.
The Mediterranean U-boat Campaign in the Mediterranean Sea was fought by Austria-Hungary and German Empire against the Allies during World War I. It was characterised by the ability of the Central Powers to raid with near impunity during the first years of the war, causing substantial shipping losses, until the introduction of the convoy system allowed the Allies to drastically cut their losses from 1917 on.
The Submarine Command Course (SMCC), previously known as the Commanding Officers Qualifying Course (COQC), and informally known as The Perisher is a training course for naval officers preparing to take command of a submarine.
Frank Massa (1906–1990) was an American engineer who contributed to the development of the field of acoustical engineering. He is best known for the development of recorded sound technology for the film industry and, during World War II, the development of the first towed sonar transducers and hydrophones used by the U.S. Navy to detect and defeat German U-boats.
