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.
• The Eberhart Steel Products Company is founded in Buffalo, New York. It specializes in manufacturing airplane parts and aeronautical equipment, and will begin to produce airplanes in 1920.
• Kawasaki Heavy Industries Company Ltd. organizes an aircraft division.
• 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.
• The British Army convenes an inquiry to look into the failure of the British offensive in the Battle of Cambrai in November–December 1917. The inquiry finds that the German use of massed aircraft for close air support of German ground troops subjected British ground troops to so much machine-gun fire that they felt helpless and became demoralized, allowing a successful German counterattack.
• January 3 – With its owner, Alfred Harmsworth, 1st Viscount Northcliffe, concerned about declining support for the war effort by the British public and believing that news about the successes of living British pilots by name would create popular heroes and improve public morale, the British newspaper the Daily Mail publishes an editorial strongly criticizing the British Army's policy of not disclosing the names of successful Royal Flying Corps pilots unless they are killed, a policy instituted because of a belief by the British Army's leadership that such publicity would harm the esprit de corps of their fellow aviators. Other Btitish newspapers quickly take up the cause, prompting the British Army to begin identifying pilots by name. France and Germany had identified their pilots to the press since early in World War I.
• 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 7 – After the British Army drops its policy of not disclosing the names of successful Royal Flying Corps pilots unless they are killed, the Daily Mail publishes "Our Wonderful Airmen – Their Names At Last," the first article in the British press identifying living RFC pilots by name. The article discusses the exploits of Captains Philip Fuller and James McCudden.
• 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.
• January 28-29 (overnight) – The first German bombing raid against the United Kingdom since December 1917 takes place when 13 Gotha and two Riesenflugzeug bombers set out to bomb England. Six Gothas turn back due to poor visibility, but the other bombers attack targets in England, killing 67 people and injuring 166, including 14 killed and 14 injured in stampedes when "maroons" – warning rockets – warn them of an imminent attack while they queue for admission to air raid shelters; another 11 people are injured by falling shrapnel from British antiaircraft shells. Many of the casualties result from a single 300-kg (661-pound) bomb that hits the Odhams printing works in Long Acre, London, where people are sheltering. British aircraft fly over a hundred defensive sorties, and two Sopwith Camels of the Royal Flying Corps's No. 40 Squadron shoot down a Gotha, the first victory over a heavier-than-air bomber over the United Kingdom for British night fighters; their pilots, Second Lieutenants Charles C. Banks and George Hackwill will receive the Distinguished Flying Cross for the achievement.
• January 29-30 (overnight) – For the first time, German Riesenflugzeug bombers attack the United Kingdom without Gotha bombers accompanying them; the four bombers are from Riesenflugzeug Abteilung ("Giant Airplane Detachment") 501 (Rfa 501). One bomber turns back. The other three bomb England, inflicting only light damage and casualties. British aircraft fly 80 defensive sorties; five of them bring one of the German bombers under attack but succeed only in disabling one of its engines, and it returns safely to base. Unfamiliar with the great size of the bombers, many of the British pilots underestimate their size and fire at them from too great a range.

February

• February 2 – The Imperial German Army's air service, the Luftstreitkräfte, forms its second and third Jagdgeschwader (fighter wings), bringing together four Jagdstaffeln (fighter squadrons) – Jagstaffeln ("Jastas") 12, 13, 15, and 19 – to form Jagdgeschwader II, with Adolf Ritter von Tutschek as its first commanding officer, and four other Jagdstaffeln – Jasta 2 "Boelcke" and Jastas 26, 27, and 36 – to form Jagdgeschwader III, with Bruno Loerzer as its first commanding officer.
• 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 () with a roundel with an outer red ring, then a blue ring, and a white center . 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.
• February 16-17 (overnight) – Four Riesenflugzeug bombers of the German Luftstreitkräfte's Riesenflugzeug Abteilung ("Giant Airplane Detachment") 501 (Rfa 501) raid England. One of them carries a single 1,000-kg (2,205-lb) bomb which it aims at London Victoria station, but it lands half a mile (0.8 km) away on the Royal Hospital, Chelsea.
• February 17-18 (overnight) – A single German Riesenflugzeug bomber attacks England. It hits St. Pancras station in London, killing 21 people and injuring 32.
• February 20 – The German high command issues a memorandum governing the employment of German ground-attack squadrons in the upcoming spring offensive on the Western Front, Operation Michael. It lays out the role of the squadrons as "flying ahead of and carrying the infantry along with them, keeping down the fire of the enemy's infantry and barrage batteries," adding that the appearance of ground-attack aircraft over the battlefield "affords visible proof to heavily engaged troops that the Higher Command is in close touch with the front, and is employing every means to support the fighting troops." It also directs the squadrons to "dislocate traffic and inflict appreciable loss on reinforcements hastening up to the battlefield."

March

• March 6

• March 15
  • South African 10-kill ace Lieutenant H. B. Redler of the Royal Flying Corps's No. 24 Squadron shoots down and kills the commanding officer of Jagdgeschwader II, Adolf Ritter von Tutschek, who is flying a green Fokker Dr.I. Tutschek's 27 victories would amount to a quarter of his parent Jagdstaffel 12's 104 victories.

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.
  • The Germans redesignate their Shutzstafffeln (escort squadrons) as Schlachtstaffeln (attack squadrons) in recognition of their close air support achievements during Operation Michael.
• March 30 – Alan Jerrard VC, a British ace with seven victories, is shot down by Benno Fiala von Fernbrugg and taken captive.

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 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 Löwenhardt's parachute fails and he falls to his death from 12,000 feet (3,658 meters). Löwenhardt'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.
