1918 in aviation

This is a list of aviation-related events from 1918:

Events

 * The Imperial Japanese Navy establishes its first lighter-than-air aviation unit.
 * The naval aviation branch of the Chilean Army's air corps receives its first aircraft.
 * Spring 1918 – Three Imperial Japanese Navy Farman-type seaplanes fly nonstop from Yokosuka to Sakai, Japan, stretching the navy's aviation distance capabilities. The cities are 391 km (243 statute miles) apart.
 * The French Army's Service Aeronautique employs four Breguet 14S air ambulances for casualty evacuation along the Aisne Front. Each aircraft can accommodate two stretcher cases.

January

 * Gunner-observer Captain John H. Hedley is thrown from the cockpit of his Bristol F2B Fighter without a parachute during a dogfight when his pilot, Captain Reginald "Jimmy" Makepeace puts the plane into a steep dive. After he falls several hundred feet, Hedley and the aircraft come back together and he manages to grab the fighter's after fuselage and crawl back into hs cockpit unharmed.
 * January 5 – A rapid series of explosions and quickly spreading fires at the Imperial German Navy airship base at Tondern destroys four hangars and five airships in five minutes, killing four civilian workers and 10 naval personnel and injuring 134 naval personnel.
 * January 9 – In a dogfight over Moorslede, Belgium, with three Royal Flying Corps aircraft – an RE.8 of No. 21 Squadron and two SE.5as of No. 60 Squadron – the Albatros D.Va of German ace Max Ritter von Müller is shot down in flames. Von Müller jumps to his death to escape the fire. Von Müller's 36 victories will make him the 15th-highest-scoring German ace and high-scoring Bavarian ace of World War I.
 * January 12 – A decree issued by the Council of Peoples' Commissars of the Republic puts all Russian aircraft manufacturing companies under state control.
 * January 25 – Second Lieutenant Carl Mather is killed in an aircraft collision at Ellington Field, Texas. The future Mather Air Force Base, later Sacramento Mather Airport, at Rancho Cordova, California, will be named for him.

February

 * February 5 – Second Lieutenant Stephen W. Thompson achieves the first aerial victory by the U.S. military.
 * February 8
 * The Lafayette Escadrille, the American volunteer squadron serving in the French Army, is transferred to the United States Army and redesignated the 103rd Aero Squadron.
 * The United States replaces the national insignia for its military aircraft adopted in 1917 (USAAC Roundel 1919-1941.svg) with a roundel with an outer red ring, then a blue ring, and a white center US Army Air Roundel.svg. The Allies had requested the change out of a fear that the star in the 1917 U.S. marking could be mistaken for a German cross. The roundel will remain in use until the United States reverts to its former markings in August 1919.

March

 * March 6
 * The Finnish Air Force is founded
 * The first successful flight of a powered unmanned heavier-than-air craft, the Curtiss-Sperry Flying Bomb, takes place. It is the precursor to modern unmanned aerial vehicles (UAVs).

The seriously injured McLeod carries the badly wounded Hammond to the British lines, and, although McLeod is wounded again in the process, both men survive. McLeod will receive the Victoria Cross for his actions in a ceremony on September 4 at the age of 19, the youngest airman to be awarded the Victoria Cross in World War I.
 * March 30 – Alan Jerrard VC, a British ace with seven victories, is shot down by Benno Fiala von Fernbrugg and taken captive.

April

 * April 1
 * The Royal Flying Corps and Royal Naval Air Service combine to form the Royal Air Force, the world's first independent air force, with Sir Hugh Trenchard as the first Chief of the Air Staff. The Women's Royal Air Force is formed at the same time.

 * April 4 – A two-seater aircraft takes off from a flying-off platform on a ship for the first time, when a Royal Air Force Sopwith 1½ Strutter launches from a platform mounted on a 12-inch (305-mm) gun turret of the Australian battlecruiser HMAS Australia (1911). By November 1918, ships of the British Grand Fleet will carry over 100 aircraft on flying-off platforms, by which time 22 light cruisers will have a flying-off platform and every battleship and battlecruiser will carry a two-seat aircraft on a platform mounted on a forward turret and a single-seat fighter on a platform mounted on an after turret.
 * April 4–5 (overnight) – Attacking the German Navy Zeppelin L 62 while piloting an F.E.2b over England, Royal Air Force Lieutenant C. H. Noble-Campbell of No. 38 Squadron is wounded in the head by machine-gun fire from L 62, but returns safely to base. It is the only occasion on which an attacking airman is wounded in combat with an airship.
 * April 7 – The German submarine UB-53 sees an airship catch fire accidentally and crash into the sea near the Strait of Otranto with the loss of all hands. It apparently is the German Navy Zeppelin L 59, modified for long-range flights, on the outbound leg of a flight from Yambol, Bulgaria, in an attempt to bomb the Royal Navy base at Malta.
 * April 8 – A flight of Airco DH.4s makes the first independent raid of World War I by aircraft of the United States Army's Aviation Section, U.S. Signal Corps, the forerunner of the United States Army Air Service.

May

 * May 10 – The German Navy Zeppelin L 62 explodes, breaks in half, and crashes in flames over the North Sea with the loss of all hands under mysterious circumstances. The German Naval Airship Service blames her loss on an accident, while the Royal Air Force claims that one of its Felixstowe F.2a flying boats shot her down.
 * May 13 – The United States issues its first air mail stamps to the public. They bear a picture depicting a Curtiss JN-4 "Jenny".

 * U.S. Army Major Harold M. Clark Jr. and Sergeant Robert P. Gay make the first interisland flight in Hawaii, flying from Fort Kamehameha on Oahu to Maui. They continue on to the island of Hawaii the same day, where they crash on the slopes of Mauna Kea. Uninjured, they wander on foot for a week before finding help.
 * May 20 - German bombs fall on London for the last time in World War I. During their one-year-long heavier-than-air bombing campaign against England, the Germans have dropped 84,745 kg (186,830 lbs) of bombs and lost 61 bombers.
 * May 21 - President Woodrow Wilson creates a Bureau of Aircraft Production responsible for aeronautical equipment.
 * May 24
 * József Kiss, Austro-Hungarian fifth-highest-scoring ace, is shot down in combat. He had scored 19 victories.
 * In Russia, Order No. 385 of the Bolshevik People's Commissariat on Military and Naval Affairs creates the Main Directorate of the Workers' and Peasants' Red Air Fleet, the predecessor of the Soviet Air Forces.
 * The United States Department of War recognizes the Bureau of Aircraft Production and the Division of Military Aeronautics as constituting the United States Army Air Service.
 * May 31 - Douglas Campbell scores his fifth victory, becoming the first American pilot to be become an ace while flying for an American-trained unit.

June

 * From the basis of VIII Brigade, the Royal Air Force forms the Independent Force, tasked to mount a strategic bombing campaign against Germany "independently" of the ground and sea campaigns the Allies have been waging since 1914.
 * A detachment of American bomber pilots is stationed in Italy to strike at Austria-Hungary.
 * The United States Marine Corps consolidates its aviation forces at the Marine Flying Field at Miami, to form the First Marine Aviation Force. Composed of four squadrons, the force will deploy to France for combat.
 * Early June – The Royal Navy destroyer HMS Vectis (D51) conducts towing trials with the NS-class blimp N.S.3 to see if an airship which runs out of fuel or suffers a mechanical breakdown can be towed at speed by a ship at sea. Vectis reaches nearly 20 knots with N.S.3 in tow during successful initial trials, but N.S.3 touches down on the sea on the final run.
 * June 1 – The Australian ace Lieutenant Colonel Roderic Dallas, flying an SE.5a, is shot down and killed over Liévin, France, by the German ace Leutnant Johannes Werner in a Fokker Dr.I as Werner's sixth victory. Dallas's victory total of 51 will make him the highest-scoring Australian ace of World War I.
 * June 4 – The first flight of the first all-metal stressed-skin fighter, the Dornier-Zeppelin D.I, takes place.
 * June 5 – Douglas Campbell, the first American to become an ace while flying for an American-trained unit, scores his sixth and final victory. Badly wounded during the flight, he sees no further combat.

July

 * During the month, the American writer William Faulkner arrives in Canada for flight training with the Royal Air Force. He still is in training there when the World War I ends, after which he returns to the United States.
 * July 9 – British ace James McCudden is killed when his aircraft crashes on take-off at Auxi-le-Château, France. He has 57 victories at the time of his death; enough to make him the seventh-highest-scoring ace of World War I.
 * July 14 – Flying a Nieuport 28, the youngest son of former U.S. President Theodore Roosevelt, Second Lieutenant Quentin Roosevelt – serving as a fighter pilot in the United States Army Air Service's 95th Aero Squadron – is shot down and killed by a German fighter over Chamery, France.
 * July 19 – Seven Royal Air Force Sopwith 2F.1 Camel fighters from the Royal Navy aircraft carrier HMS Furious (47) attack the Imperial German Navy airship base at Tondern, destroying the Zeppelins L 54 and L 60. It is history's first air attack by conventional land planes launching from an aircraft carrier's flight deck and the most successful attack by shipboard aircraft of World War I. All seven Camels are lost: one crashes into the sea in bad weather, killing its pilot; two ditch in the sea, and their pilots are rescued by the British naval force escorting Furious; and four land in neutral Denmark, where they and their pilots are interned. One of the pilots recovered from the sea – Captain William F. Dickson, rescued by the destroyer HMS Violent (D57) – is a future Marshal of the Royal Air Force, Chief of the Air Staff, and Chief of the Defence Staff.
 * July 21 – Two United States Navy seaplanes from Naval Air Station Chatham, Chatham, Massachusetts, attack a surfaced German submarine that is firing at a tug and three barges off Cape Cod, Massachusetts. One bomb strikes the submarine, but is a dud.
 * July 26 – Major Edward "Mick" Mannock, the United Kingdom's highest scoring ace of the war, is shot down by German ground fire and killed. He traditionally is credited with 73 victories as the highest-scoring British ace of World War I, but he never claimed that many and his actual score may have been 61.
 * July 30
 * Lieutenant Frank Linke-Crawford, the fourth-highest-scoring Austro-Hungarian ace, is shot down and killed in aerial combat. He had scored 27 victories.
 * The United States Marine Corps's 1st Marine Aviation Force, minus one of its four squadrons, arrives at Brest, France, to become the first U.S. Marine Corps aviation force to serve in combat. Delays in transportation and the arrival of equipment will prevent it from operating until mid-October.
 * July 31
 * An aircraft takes off from platform installed on a towed lighter for the first time, when Royal Air Force Lieutenant Stewart Culley takes off in a Sopwith Camel from a lighter towed behind a British warship.
 * A Royal Air Force bombing raid over Germany by 12 Airco DH.9s suffers the loss of 10 aircraft shot down.

August

 * A large petroleum barge on the Volga River in Russia is equipped with a flight deck and elevators (lifts) to carry up to nine Grigorovich M.9 flying boats and three Nieuport fighters. Named Kommuna and towed by a sidewheel paddle tug, she and her aircraft actively support operations of the Bolshevik Volga River Flotilla during the Russian Civil War.
 * August 1
 * In the North Russia Campaign during the Russian Civil War, probably the first fully combined air, sea, and land military operation in history takes place, as Fairey Campania seaplanes from the Royal Navy seaplane carrier HMS Nairana (1917) join Allied ground forces and ships in driving Bolsheviks out of their fortifications on Modyugski Island at the mouth of the Northern Dvina River in Russia, then scout ahead of the Allied force as it proceeds up the channel to Arkhangelsk. The appearance of one of the Campanias over Arkhangelsk induces the Bolshevik leaders there to panic and flee.
 * French ace Lieutenant Gabriel Guérin is killed in action. His 23 victories will tie him with Lieutenant René Dorme for ninth-highest-scoring French ace of World War I.
 * August 5–6 (overnight) – Five Imperial German Navy Zeppelins attempt to bomb the United Kingdom in the fourth and final such raid of 1918. All of their bombs fall through clouds into the North Sea, and the commander of the Naval Airship Division, Fregattenkapitän Peter Strasser, is killed in action when a Royal Air Force Airco DH.4 piloted by Major Egbert Cadbury and crewed by Captain Robert Leckie shoots down in flames the Zeppelin in which he is flying as an observer, L70, over the coast of England. After Strasser's death, Germany attempts no more airship raids against the United Kingdom. During their 1915-1918 bombing campaign, German airships have made 208 raids against England, dropped 5,907 bombs, killed 528 people, and injured 1,156.
 * August 9 – Eight Italian Ansaldo SVA biplanes of the 87 Squadriglia "Serenimissa", led by Gabriele d'Annunzio, fly over Vienna for 30 minutes without interference from Austro-Hungarian forces, taking photographs and dropping leaflets before returning to base without loss.
 * August 10
 * During a dogfight, the Fokker D.VII fighter of the German fighter ace Oberleutnant Erich Löwenhardt collides with another D.VII flown by Leutnant Alfred Wenz near Chaulnes, France. Both men bail out; Wenz survives, but Loewenhardt's parachute fails and he falls to his death from 12,000 feet (3,658 meters). Loewenhardt's score of 53 kills will make him the third-highest-scoring German ace of World War I.
 * After shooting down two enemy aircraft earlier in the day, the German ace Rudolf Berthold collides with an enemy plane during a dogfight with Sopwith Camels. His Fokker D.VII crashes into a house, injuring him; although he survives, he never flies another combat mission. His total of 44 kills will make him the sixth-highest-scoring German ace of World War I.
 * August 11
 * After taking off in a Sopwith Camel from a barge towed behind the destroyer HMS Redoubt, Royal Air Force Flight Sub-Lieutenant Stuart Culley shoots down the Imperial German Navy Zeppelin L 53, which had been flying a scouting mission over the North Sea. It is the first successful interception of an enemy aircraft by a shipborne fighter. German airships never conduct another scouting mission. L 53's sole survivor is a crewman who parachutes from the Zeppelin at an altitude of 19,000 feet (5,791 m), almost certainly a record at the time. L 53 is the last German airship destroyed during World War I.
 * The first use of a parachute from an airplane in combat occurs when a German pilot escapes his burning Pfalz D.III after being attacked by a pilot from the Royal Air Force's No. 19 Squadron.
 * August 14 – The French ace René Fonck shoots down three German aircraft in ten seconds in a head-on attack. All three crash within 100 meters (328 feet) of one another near Roye, France.

 * September 27 – During a dogfight with SE.5as of No. 32 Squadron, Royal Air Force, the Fokker D.VII fighter of the German ace Leutnant Fritz Rumey either collides with the SE.5a of Captain George Lawson or is shot down by Lieutenant Frank Hale. Rumey parachutes from his D.VII at 1,000 feet (305 meters) but falls to his death when his parachute fails. His 45 kills will make him the fifth-highest-scoring German ace of World War I.
 * September 28 – Flying an Airco DH.9 with the Royal Air Force's No. 218 Squadron, U.S. Marine Corps First Lieutenant Everett R. Brewer (pilot) and Gunnery Sergeant Harry B.

On the return flight, German Fokker D.VII and Pfalz D.III fighters attack the bombers. Second Lieutenant Ralph Talbot (pilot) and Gunnery Sergeant Robert Guy Robinson (gunner) become separated from the formation after their DH.4 loses power, then encounter 12 German fighters. Although Robinson is terribly wounded during the resulting dogfight, they hold off the Germans and Talbot lands at a Belgian hospital, where Robinson is treated. For this action, they will become the first U.S. Marine Corps aviators to receive the Medal of Honor during a ceremony on November 11, 1920.
