Air-sea rescue operations carried out during times of conflict have been credited with saving valuable trained and experienced airmen. Moreover, the knowledge that such operations are being carried out greatly enhanced the morale of the combat aircrew faced not only with the expected hostile reaction of the enemy but with the possible danger of aircraft malfunction during long overwater flights.

Origins

Initial air-sea rescue operations were performed either by

s; these were the pioneering approach used to pick up aviators or sailors who were has come into difficulties in the water. Any other aircraft design posed the additional danger of ditching in the water and requiring immediate rescue, while seaplanes could land on the water in an emergency and wait for rescue. Qualities such as their long range, endurance, and the ability to stay on station for long periods of time were commonly viewed as essential naval aviation requirements for rescue aircraft. Robust radio equipment was necessary for contact with land and ocean surface forces. Training and weather accidents could require an aircrew to be rescued, and seaplanes were occasionally used for that purpose. The limitation was that if the water's surface were too rough, the aircraft would not be able to land. The most that could be done was to drop emergency supplies to the survivors, or to signal surface ships or rescue boats to guide them to the correct location. An early air-sea rescue was performed in August 1911 by Hugh Robinson who landed his Curtiss Aeroplane Company seaplane on

. Some rescues were performed, however, by individuals and groups acting on their own initiative, such as the United States Navy Reserve pilot Ensign Charles Hammann who, during the Adriatic Campaign, rescued a fellow aviator adrift in the Adriatic Sea by landing on the water in his seaplane. When the Marine Craft Section of the newly formed RAF, was formed in 1918, it inherited over 200 operational vessels, from the RNAS. These boats were regarded primarily as

Interwar development


Britain

T. E. Lawrence Thomas Edward Lawrence (16 August 1888 – 19 May 1935) was a British archaeologist, army officer, diplomat, and writer who became renowned for his role in the Arab Revolt (1916–1918) and the Sinai and Palestine Campaign (1915–1918 ...

, despatched to save the survivors of an airplane crash in the Solent, arrived too late to save them before they drowned. He immediately began to press his commanding officer for the introduction of fast motorboat launches as rescue boats. Lawrence had experience using this type of vessel, having assisted with the 1929 Schneider Trophy race while at the helm of a Biscayne Baby, a fast boat when the temperamental engines were running. Meanwhile, Hubert Scott-Paine, the designer of the record breaking Miss Britain III and Miss England boats and founder of the

(BPBC), made a similar offer of his expertise to the RAF and he soon began to collaborate with Lawrence in the development of long high-speed launches, purpose-built for sea rescue. The result, built by the BPBC, was the 200-Class Seaplane tender; powered by two 100 HP engines it had a top speed of over 36 knots. Testing on the launch continued from 1931–32 to ensure that the engines could run at sustained high speeds. The ship was an operational success and was followed up with the MkI and MkIA tenders, powered with

aircrew from the sea after they were shot down. The failure of the Marine Craft Section during the Battle of Britain led to the creation of the Air Sea Rescue Services which with the motto 'the sea shall not have them', was created to coordinate at sea rescue with its own air sea rescue squadrons, Marine Branch and Royal Navy vessels, and Coastal Command flying boats.


Germany

The principles of coordinating small surface boat rescue efforts with direction and assistance from air units were developed in the 1930s in Germany. In 1935, Lieutenant Colonel Konrad Goltz of the German Air Force ('' Luftwaffe''), a supply officer based at the port of Kiel, was given the task of organizing the ''Seenotdienst'' (Sea Rescue Service), an air-sea rescue organization focusing on the North Sea and the Baltic Sea. To this end, Goltz gained coordination with aircraft units of the ''

'' as well as with civilian lifeboat societies. Early in 1939, with the growing probability of war against Great Britain, the ''Luftwaffe'' carried out large-scale rescue exercises over water. Land-based German bombers used for search duties proved inadequate in terms of range, thus new bomber air bases were constructed along the coast to facilitate an air net over the Baltic and North seas. Following this, the ''Luftwaffe'' determined to procure a purpose-built air-sea rescue seaplane, choosing the Heinkel He 59, a twin-engine biplane with pontoons. A total of 14 He 59s were sent to be fitted with first aid equipment, electrically heated sleeping bags, artificial respiration equipment, a floor hatch with a telescoping ladder to reach the water, a hoist, signaling devices, and lockers to hold all the gear.


United States

The United States Coast Guard acquired its first seaplanes in 1925 at Air Station Gloucester, and used them for coastal patrol as well as single, uncoordinated air rescue units. The air complement grew in the 1930s with the establishment of Air Station Salem and in the 1940s with the first formation of a dedicated U.S. domestic air-sea rescue service on the

The first multiple air-sea rescue operation occurred on 18 December 1939. A group of 24 British Vickers Wellington medium bombers were frustrated by low clouds and fog in their mission to bomb Wilhelmshaven, and they turned for home.

later wrote "We did not recognise this means of rescuing enemy pilots who had been shot down in action, in order that they might come and bomb our civil population again." Germany protested against this order on the grounds that rescue aircraft were part of the Geneva Convention agreement stipulating that belligerents must respect each other's "mobile sanitary formations" such as field ambulances and hospital ships. Churchill argued that rescue aircraft were not anticipated by the treaty, and were not covered. British attacks on He 59s increased. The ''Seenotdienst'' ordered the rescue aircraft armed as well as painted in the camouflage scheme of their area of operation. Rescue flights were to be protected by fighter aircraft when possible. In October 1940, yellow-painted Sea Rescue Floats were placed by the Germans in waters where air emergencies were likely. The highly visible buoy-type floats held emergency equipment including food, water, blankets and dry clothing, and they attracted distressed airmen from both sides of the war. Both German and British rescue units checked the floats from time to time, picking up any airmen they found, though enemy airmen were immediately made prisoner of war.


Britain

Prior to the Second World War, there was still no fully functional coordinated British air-sea rescue organisation for rescuing aircrew from the sea. The aircrew relied on the High Speed Launches (HSL) established at flying boat bases. On 14 January 1941, the first air-sea rescue was set up (the Directorate of Air Sea Rescue Services). The service the aircraft used were diverse. Westland Lysanders were used to scouting the coastlines, while the

along with an instruction book to teach aircrew the rudiments of sailing. The lifeboats were first carried by Lockheed Hudson aircraft in February 1943. Later, Vickers Warwick bombers carried the Mark II lifeboat. The Fox boats successfully saved downed aircrew as well as glider infantrymen dropped in the water during Operation Market-Garden. The lifeboats carried emergency equipment, a radio, waterproof suits, rations and medical supplies. Aircraft suitability once again came in for discussion during the war. Ansons and Boulton Paul Defiants were not suitable for ASR operations. The Vickers Warwick was earmarked for the main ASR aircraft. Four 20-aircraft squadrons with specialised ASR conversion were to be made available by the spring, 1943. While development was slow, the effort paid off. In May 1943, 156 men of Bomber Command were rescued from the sea by No. 279 Squadron alone.

Other helicopters, such as the Sea King and the Seaguard, were made with a water-resistant hull which allowed them to settle directly onto the water for long enough to effect a rescue.Ostrom 2004, p. 186.

s came to the fore during the 1960s, but have been largely replaced by helicopters unable to land on water, due to high aircraft development costs. Amphibious helicopters paid dividends for rescue personnel who enjoyed greater safety and success during operations. Operations that use non-amphibious helicopters rely to a higher degree on hoists, rescue baskets, and rescue swimmers. Helicopters became frequently used, due to a number of advantages; they could fly in rougher weather than

and could deliver injured passengers directly to hospitals or other emergency facilities. Helicopters can hover above the scene of an accident while fixed-wing aircraft must circle, or for seaplanes, land and taxi toward the accident. Helicopters can save those stranded among rocks and reefs, where seaplanes are unable to go. Landing facilities for helicopters can be much smaller and cruder than for fixed-wing aircraft. Additionally, the same helicopter that is capable of air-sea rescue can take part in a wide variety of other operations including those on land. Disadvantages include the loud noise causing difficulties in communicating with the survivors and the strong downdraft that the hovering helicopter creates which increases

Korean War

Toward the end of World War II, several B-29 bombers on each large-scale bombing mission were emptied of ammunition, filled with rescue supplies and rotated through Super Dumbo patrol duty as their squadron mates lumbered off filled with bombs. Following that conflict, 16 B-29 bombers were converted to full-time air–sea rescue duty and redesignated SB-29 Super Dumbo. The SB-29 served throughout the

Shortly after the Korean War, some Douglas C-54 Skymasters were converted to air-sea rescue work and redesignated SC-54; the type quickly replaced all of the remaining Flying Fortresses and Super Fortresses still in service. The SC-54 sometimes carried an airborne lifeboat and could carry more rescue supplies over longer distances.

. The helicopter most closely associated with long-range U.S. air-sea rescue operations in Southeast Asia was the Sikorsky S-61R, called the "Pelican" or "Jolly Green Giant", a variation of the SH-3 Sea King. First acquired by the U.S. Navy in 1961 for anti-submarine warfare, variants of the helicopter were quickly utilized for many duties including rescue, and were operated as well by the United States Air Force (USAF) which developed an in-flight refueling system. In 1970, USAF Air Rescue and Recovery Service (ARRS) Sea Kings performed a Transatlantic flight from the U.S. to France using such refueling methods.McGowan 2005, p. 119. At the same time as the Vietnam War, U.S. Navy helicopters were used during the Apollo space missions to pull astronauts and their capsules from the ocean.

Rescue swimmer

Rescue swimmers have been used for air-sea rescue work to assist in picking up survivors who are not able to reach the rescue craft, especially those incapacitated by exposure to cold water.Laguardia-Kotite and Ridge 2008, pp. 2–4. Since the mid-1980s when standards were set down for their instruction and implementation, rescue swimmers have deployed from rescue helicopters or rescue boats and have been trained to extricate downed airmen from fouled parachute lines and ejection seats. Rescue swimmers must meet a number of difficult requirements: their physical conditioning must be kept at a high level, they must be expert in first aid treatment methods, and they are often highly trained technicians crucial to the operation of the rescue craft.Ostrom 2004, p. 174.
