Naval aviation


Naval aviation is the application of military air power by navies, either from warships that can embark aircraft or from coastal naval air stations.
It often involves navalised aircraft, specifically designed for naval use.
Seaborne aviation encompasses similar activities not restricted to navies, including marines and coast guards, such as in U.S. naval aviators. As with most army aviation units, naval aviation units are generally separate from a nation's dedicated air force.
Naval aviation operations are typically projected by way of carrier-based aircraft, which must be sturdy enough to withstand the demands of shipborne operations at sea. They must be able to take off from a short runway and be sturdy and flexible enough to come to a sudden stop when landing; they typically have robust folding or swinging wings that reduce the occupied space and thus allow more of them to be stored in below-decks hangars and limited parking spaces on flight decks. These aircraft are designed for many tactical purposes, including aerial combat, airstrike/close air support, anti-submarine warfare, early warning, search and rescue, matériel transport, weather observation, patrol and reconnaissance, and wide-area command and control duties.
Naval aviation first started in the mid-19th century with the use of aerostats such as balloons tethered to balloon tenders, later the use of powered ship-launched airships, for both observation and firebombing, until these were superseded by propeller-powered seaplanes launched from seaplane carriers during the First World War. By the end of the Second World War, aircraft carrier-launched fixed-wing aircraft such as dive bombers and torpedo bombers had dramatically changed the nature of naval warfare, leading to the decline of gun-oriented battleships as fleet capital ships. Nowadays, naval helicopters are used ubiquitously as VTOL aircraft by most navies and perform many of the same missions as fixed-wing aircraft, although the latter have the advantages of significantly faster airspeed, longer operational ranges and heavier payloads. However, helicopters and other VSTOL aircraft can be readily operated from aircraft carriers, helicopter carriers, amphibious warfare ships and aviation-capable surface combatants equipped with stern helipad such as cruisers, destroyers, frigates and even some corvettes, while fixed-wing aircraft can only be operated from large carriers with a sufficiently long flight deck and mandatorily also STOL-assisting devices such as ski-jump/catapults, arresting gears and optical landing systems.

History

Establishment

Early experiments on the use of kites for naval reconnaissance took place in 1903 at Woolwich Common for the Admiralty. Samuel Franklin Cody demonstrated the capabilities of his 8-foot-long black kite and it was proposed for use as either a mechanism to hold up wires for wireless communications or as a manned reconnaissance device that would give the viewer the advantage of considerable height.
In 1908 Prime Minister H. H. Asquith approved the formation of an "Aerial Sub-Committee of the Committee of Imperial Defence" to investigate the potential for naval aviation. In 1909 this body accepted the proposal of Captain Reginald Bacon made to the First Sea Lord Sir John Fisher that rigid airships should be constructed for the Royal Navy to be used for reconnaissance. This resulted in the construction of Mayfly in 1909, the first air component of the navy to become operational, and the genesis of modern naval aviation.
The first pilots for the Royal Navy were transferred from the Royal Aero Club in June 1910 along with two aircraft with which to train new pilots, and an airfield at Eastchurch became the Naval Flying School, the first such facility in the world. Two hundred applications were received, and four were accepted: Lieutenant C R Samson, Lieutenant A M Longmore, Lieutenant A Gregory and Captain E L Gerrard, RMLI.
The French also established a naval aviation capability in 1910 with the establishment of the Service Aeronautique and the first flight training schools.
U.S. naval aviation began with pioneer aviator Glenn Curtiss who contracted with the United States Navy to demonstrate that airplanes could take off from and land aboard ships at sea. One of his pilots, Eugene Ely, took off from the cruiser anchored off the Virginia coast in November 1910. Two months later Ely landed aboard another cruiser,, in San Francisco Bay, proving the concept of shipboard operations. However, the platforms erected on those vessels were temporary measures. The U.S. Navy and Glenn Curtiss experienced two firsts during January 1911. On 27 January, Curtiss flew the first seaplane from the water at San Diego Bay and the next day U.S. Navy Lt. Theodore G. Ellyson, a student at the nearby Curtiss School, took off in a Curtiss "grass cutter" plane to become the first naval aviator.
$25,000 was appropriated for the Bureau of Navigation to purchase three airplanes and in the spring of 1911 four additional officers were trained as pilots by the Wright brothers and Curtiss. A camp with a primitive landing field was established on the Severn River at Greenbury Point, near Annapolis, Maryland. The vision of the aerial fleet was for scouting. Each aircraft would have a pilot and observer. The observer would use the wireless radio technology to report on enemy ships. Some thoughts were given to deliver counterattacks on hostile aircraft using "explosives or other means". Using airplanes to bomb ships was seen as largely impractical at the time. CAPT Washington Irving Chambers felt it was much easier to defend against airplanes than mines or torpedoes. The wireless radio was cumbersome, but the technology was improving. Experiments were underway for the first ICS using headsets, as well as connecting the observer to the radio. The navy tested both telephones and voice tubes for ICS. As of August 1911, Italy was the only other navy known to be adapting hydroplanes for naval use.
The group expanded with the addition of six aviators in 1912 and five in 1913, from both the Navy and Marine Corps, and conducted maneuvers with the Fleet from the battleship, designated as the Navy's aviation ship. Meanwhile, Captain Henry C. Mustin successfully tested the concept of the catapult launch in August 1912, and in 1915 made the first catapult launching from a ship underway. The first permanent naval air station was established at Pensacola, Florida, in January 1914 with Mustin as its commanding officer. On April 24 of that year, and for a period of approximately 45 days afterward, five floatplanes and flying boats flown by ten aviators operated from Mississippi and the cruiser Birmingham off Veracruz and Tampico, Mexico, respectively, conducting reconnaissance for troops ashore in the wake of the Tampico Affair.
In January 1912, the British battleship took part in aircraft experiments at Sheerness. She was fitted for flying off aircraft with a downward-sloping runway which was installed on her foredeck, running over her forward gun turret from her forebridge to her bow and equipped with rails to guide the aircraft. The Gnome-engined Short Improved S.27 "S.38", pusher seaplane piloted by Lieutenant Charles Samson become the first British aircraft to take-off from a ship while at anchor in the River Medway, on 10 January 1912. Africa then transferred her flight equipment to her sister ship.
In May 1912, with Commander Samson again flying the "S.38", the first ever instance of an aircraft to take off from a ship which was under way occurred. Hibernia steamed at at the Royal Fleet Review in Weymouth Bay, England. Hibernia then transferred her aviation equipment to battleship. Based on these experiments, the Royal Navy concluded that aircraft were useful aboard ship for spotting and other purposes, but that interference with the firing of guns caused by the runway built over the foredeck and the danger and impracticality of recovering seaplanes that alighted in the water in anything but calm weather more than offset the desirability of having airplanes aboard. In 1912, the nascent naval air detachment in the United Kingdom was amalgamated to form the Royal Flying Corps and in 1913 a seaplane base on the Isle of Grain, an airship base at Kingsnorth and eight new airfields were approved for construction. The first aircraft participation in naval manoeuvres took place in 1913 with the cruiser converted into a seaplane carrier. In 1914, naval aviation was split again, and became the Royal Naval Air Service. However, shipboard naval aviation had begun in the Royal Navy, and would become a major part of fleet operations by 1917.
Other early operators of seaplanes were Germany, within its Marine-Fliegerabteilung naval aviation units within the Kaiserliche Marine, and Russia. In May 1913 Germany established a naval zeppelin detachment in Berlin-Johannisthal and an airplane squadron in Putzig. The Japanese established the Imperial Japanese Navy Air Service, modelled on the RNAS, in 1913. On 24 January 1913 came the first wartime naval aviation interservice cooperation mission. Greek pilots on a seaplane observed and drew a diagram of the positions of the Turkish fleet against which they dropped four bombs. This event was widely commented upon in the press, both Greek and international.

World War I

At the outbreak of war the Royal Naval Air Service had 93 aircraft, six airships, two balloons and 727 personnel, making it larger than the Royal Flying Corps. The main roles of the RNAS were fleet reconnaissance, patrolling coasts for enemy ships and submarines, attacking enemy coastal territory and defending Britain from enemy air-raids, along with deployment along the Western Front. In 1914 the first aerial torpedo was dropped in trials performed in a Short "Folder" by Lieutenant Arthur Longmore, and in August 1915, a Short Type 184 piloted by Flight Commander Charles Edmonds from sank a Turkish supply ship in the Sea of Marmara with a, torpedo.
The first strike from a seaplane carrier against a land target as well as a sea target took place in September 1914 when the Imperial Japanese Navy carrier conducted ship-launched air raids from Kiaochow Bay during the Battle of Tsingtao in China. The four Maurice Farman seaplanes bombarded German-held land targets and damaged a German minelayer in the Tsingtao peninsula from September until 6 November 1914, when the Germans surrendered. One Japanese plane was credited being shot down by the German aviator Gunther Plüschow in an Etrich Taube, using his pistol.
On the Western front the first naval air raid occurred on 25 December 1914 when twelve seaplanes from, and attacked the Zeppelin base at Cuxhaven. The raid was not a complete success, owing to sub-optimal weather conditions, including fog and low cloud, but the raid was able to conclusively demonstrate the feasibility of air-to-land strikes from a naval platform. Two German airships were destroyed at the Tøndern base on July 19, 1918, by seven Sopwith Camels launched from the carrier.
In August 1914 Germany operated 20 planes and one Zeppelin, another 15 planes were confiscated. They operated from bases in Germany and Flanders. On 19 August 1918 several British torpedo boats were sunk by 10 German planes near Heligoland. These are considered as the first naval units solely destroyed by airplanes. During the war the German "Marineflieger" claimed the destruction of 270 enemy planes, 6 balloons, 2 airships, 1 Russian destroyer, 4 merchant ships, 3 submarines, 4 torpedo boats and 12 vehicles, for the loss of 170 German sea and land planes as well as 9 vehicles. Notable Marineflieger aces were Gotthard Sachsenberg, Alexander Zenzes, Friedrich Christiansen, Karl Meyer, Karl Scharon, and Hans Goerth.
