A seaplane is a powered fixed-wing aircraft capable of taking off and landing (alighting) on water. Seaplanes are usually divided into two categories based on their technological characteristics: floatplanes and flying boats; the latter are generally far larger and can carry far more. Seaplanes that can also take off and land on airfields are in a subclass called amphibious aircraft, or amphibians. Seaplanes were sometimes called hydroplanes, but currently this term applies instead to motor-powered watercraft that use the technique of hydrodynamic lift to skim the surface of water when running at speed.
A seaplane tender is a boat or ship that supports the operation of seaplanes. Some of these vessels, known as seaplane carriers, could not only carry seaplanes but also provided all the facilities needed for their operation; these ships are regarded by some as the first aircraft carriers and appeared just before the First World War.
The Type Two HSL was a 63 ft high-speed launch craft made by British Power Boat Company (BPBC). The craft were used during the Second World War for air-sea rescue operations to save Allied aircrew from the sea. The Type Two superseded the 64 ft HSL, and was itself replaced by the Type Three 68 ft "Hants and Dorset" also built by the BPBC. The Type Two was nicknamed the "Whaleback" due to the distinctive curve to its deck and humped cabin.

Air-sea rescue, and aeronautical and maritime search and rescue (AMSAR) by the ICAO and IMO, is the coordinated search and rescue (SAR) of the survivors of emergency water landings as well as people who have survived the loss of their seagoing vessel. ASR can involve a wide variety of resources including seaplanes, helicopters, submarines, rescue boats and ships. Specialized equipment and techniques have been developed. Both military and civilian units can perform air-sea rescue. Its principles are laid out in the International Aeronautical and Maritime Search and Rescue Manual. The International Convention on Maritime Search and Rescue is the legal framework that applies to international air-sea rescue.
Royal Air Force Martlesham Heath or more simply RAF Martlesham Heath is a former Royal Air Force station located 1.5 miles (2.4 km) southwest of Woodbridge, Suffolk, England. It was active between 1917 and 1963, and played an important role in the development of airborne radar.
Royal Air Force Boreham or more simply RAF Boreham is a former Royal Air Force station in Essex, England. The airfield was always known locally as : "Boreham Airfield". The airfield is located approximately 4 miles (6.4 km) north-northeast of Chelmsford; about 30 miles (48 km) northeast of London.
Royal Air Force Calshot or more simply RAF Calshot was initially a seaplane and flying boat station, and latterly a Royal Air Force marine craft maintenance and training unit. It was located at the end of Calshot Spit in Southampton Water, Hampshire, England, at grid reference SU487024. It was the main seaplane/flying boat development and training unit in the UK, with the landing area sheltered by the mainland, to the west, north and east, and the Isle of Wight, a few miles away to the south on the other side of the Solent, where seaplanes and flying boats were mass-produced by Saunders-Roe. It closed in 1961. Much of the former base has been preserved, with most of the site now being occupied by the Calshot Activities Centre.

Dumbo was the code name used by the United States Navy during the 1940s and 1950s to signify search and rescue missions, conducted in conjunction with military operations, by long-range aircraft flying over the ocean. The purpose of Dumbo missions was to rescue downed American aviators as well as seamen in distress. Dumbo aircraft were originally land-based heavy bomber aircraft converted to carry an airborne lifeboat to be dropped in the water near survivors. The name "Dumbo" came from Walt Disney's flying elephant, the main character of the animated film Dumbo, appearing in October 1941.
Airborne lifeboats were powered lifeboats that were made to be dropped by fixed-wing aircraft into water to aid in air-sea rescue operations. An airborne lifeboat was to be carried by a heavy bomber specially modified to handle the external load of the lifeboat. The airborne lifeboat was intended to be dropped by parachute to land within reach of the survivors of an accident on the ocean, specifically airmen survivors of an emergency water landing. Airborne lifeboats were used during World War II by the United Kingdom and on Dumbo rescue missions by the United States from 1943 until the mid-1950s.
The Marine Branch (1918–1986) was a branch of the Royal Air Force (RAF) which operated watercraft in support of RAF operations. Just days after the creation of the RAF itself, the Marine Craft Section (MCS) was created with the transfer of Royal Naval Air Service (RNAS) vessels and personnel to the new service. Originally tasked with the support of RNAS, and later RAF, seaplanes, Marine Craft Section was to achieve its greatest size during the Second World War, and achieved fame for its role in air-sea rescue operations. After the war MCS was granted full branch status on 11 December 1947; however, post-war the role of the new branch became greatly reduced with the end of the British Empire, the withdrawal of flying boats from service, and the increasing use of helicopters in air-sea rescue. The branch was disestablished on 8 January 1986.
The 22nd Crash Rescue Boat Squadron was a U.S. Air Force combat search and rescue unit formed during the Korean War. While its original task was ocean rescue of downed pilots, its speedy and well-armed boats soon became prime vehicles for inserting spies, espionage agents, and sabotage parties into enemy territory for the 6004th Air Intelligence Service Squadron. Despite the hazards of both their overt and covert missions, the airmen of the 22nd CRBS never lost a boat during their clandestine operations in the war.

Crash boats, at the time known as "aircraft rescue boats" or "air-sea rescue boats", were United States high speed boats built to rescue the crew of downed Allied aircraft during World War II. US boats came from the observation of British experience with high-speed launches (HSL) by the Royal Air Force Marine Branch during the Battle of Britain.

These boats were built in small boatyards on the West coast and East coast, Great Lakes and the Gulf of Mexico. They could be built quickly, in just 60 to 120 days. Most of the boats were built by boatyards that already had the tools and knowledge from building yachts, sailboats and motor boats. Many were built by craftsmen in family-owned small businesses. Under the Emergency Shipbuilding Program and War Shipping Administration contracts went out to over fifty boatyards across the country. The boats were built for the US Navy, the United States Army Air Forces, United States Coast Guard, and US Army. Some of the wooden boats went to Allied nations on the Lend-Lease program.
