This is a list ofaviation-related events from 1918:

• TheImperial Japanese Navy establishes its firstlighter-than-air aviation unit.^[1]
• The naval aviation branch of theChilean Army's air corps receives its first aircraft.^[2]
• TheEberhart Steel Products Company is founded inBuffalo, New York. It specializes in manufacturing airplane parts and aeronautical equipment and will begin to produce airplanes in 1920.^[3]
• Kawasaki Heavy Industries Company Ltd. organizes an aircraft division.^[4]
• Spring 1918 – Three Imperial Japanese NavyFarman-typeseaplanes fly nonstop fromYokosuka toSakai, Japan, stretching the navy's aviation distance capabilities.^[5] The cities are 391 km (243 mi) apart.

After he falls several hundred feet, Hedley and the aircraft come back together and he manages to grab the fighter's afterfuselage and crawl back into his cockpit unharmed.^[7]
• TheBritish Army convenes an inquiry to look into the failure of the British offensive in theBattle of Cambrai in November–December 1917. The inquiry finds that the German use of massed aircraft forclose air support of German ground troops subjected British ground troops to so muchmachine-gun fire that they felt helpless and became demoralized, allowing a successful German counterattack.^[8]
• 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 theDaily Mail publishes an editorial strongly criticizing the British Army's policy of not disclosing the names of successfulRoyal 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 theesprit de corps of their fellow aviators. Other British 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.^[9]
• January 5 – A rapid series of explosions and quickly spreading fires at theImperial German Navy airship base atTondern destroys fourhangars and fiveairships in five minutes, killing four civilian workers and 10 naval personnel and injuring 134 naval personnel.^[10]

Another 11 are injured by shrapnel from British antiaircraft shells. Most of the casualties are from a single 300 kg (660 lb) bomb that hitsOdhams Press inLong Acre, London, where people are sheltering. British aircraft fly over a hundred defensive sorties, and twoSopwith Camels of the Royal Flying Corps'sNo. 40 Squadron shoot down a Gotha, the first victory over aheavier-than-air bomber over the United Kingdom for Britishnight fighters.

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.^[15][16] 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.

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."
