The twin-engine German giant that carried out the first sustained strategic bombing campaign against a civilian population. Flying in formations of up to 20 aircraft from occupied Belgium, it struck London and southeast England through 1917 and 1918, forcing Britain to divert fighter squadrons home from the Western Front. Developed by Gothaer Waggonfabrik.

The Gotha G.IV is a German twin-engine biplane bomber built by Gothaer Waggonfabrik and used to bomb London during the First World War. From May 1917 it flew daylight formation raids over England, one of the first sustained strategic bombing campaigns against a civilian population.[1]
Around 230 were built. The raids killed relatively few people but caused widespread panic, prompting Britain to recall fighter squadrons from France, build an integrated air-defence system, and, in April 1918, form the Royal Air Force - the world's first independent air force.[2]
Germany's strategic bombing arm began the war riding hydrogen: Zeppelins raided England from 1915, but by 1916 Britain's incendiary-armed night fighters were burning them out of the sky. The Luftstreitkräfte's answer was the Grossflugzeug - the 'large aeroplane' - and Gothaer Waggonfabrik's G-series matured, by the G.IV of late 1916, into a machine specifically shaped for one mission: England.[1]
Operation Türkenkreuz ('Turk's Cross') was the plan[3] - daylight formation raids on London from bases in occupied Belgium - and the G.IV its instrument: three crew, two pusher Mercedes engines, and the ceiling and armament to make interception, in 1917, close to hopeless.[1]
The G.IV's cleverest feature pointed backwards: the 'Gotha tunnel', an open channel through the rear fuselage letting the gunner fire downward and astern - covering the blind spot beneath the tail where every fighter of the era preferred to attack. Pilots who dove in from below, expecting safety, met a machine gun; the trick killed enough of them to become legend.[1]
Otherwise it was honest wartime engineering: a 78-foot biplane of wood, fabric and plywood, up to ~500 kg of bombs for London (more on shorter runs), crew stations open to a freezing slipstream at 15,000+ feet - altitudes demanding oxygen the crews rarely had. Its true weakness waited at home: nose-heavy with tanks empty, the Gotha was notoriously lethal to land, and more were lost to landing accidents than to British defences.[2]
The daylight campaign of May-August 1917 was the Gotha's high summer: Folkestone, then London twice, formations of twenty droning up the Thames in diamond formation while defences flailed. The 13 June raid remains the deadliest single air raid on Britain of the entire war - and not one Gotha fell to the defenders that day.[1]
Britain's response built the future: fighter squadrons pulled home, the London Air Defence Area integrating guns, balloons, and interceptors under one command[4], and - when massed defences finally made daylight suicidal by September - the Gothas switched to the war's first sustained night-bomber campaign, pioneering everything from blackout Britain to the 'Harvest Moon' raid sequences of 1917-18.[2]
Attrition told, as it always does against defended capitals: of the sixty-odd Gothas lost on England raids, most crashed on landing rather than to enemy action, and the campaign wound down in May 1918 with London's defences - not Germany's bombers - the lasting military creation.[1]
Around 230 G.IVs were built (some under licence by LVG), succeeded by the longer-legged G.V family that carried the night campaign; Austria-Hungary flew licence-built examples against Italy. The type's production story is modest - it was the doctrine, not the airframe count, that mattered.[1]
Not one Gotha bomber survives anywhere: postwar destruction under the Versailles treaty erased the fleet so completely that the aircraft that changed air power exists today only in photographs, fragments and museum replicas - an absence that itself says something about how seriously the victors took it.[2]
The Gotha raids are where strategic air power's whole debate begins: the first demonstration that a capital's civilians were targets, the first public panic and shelter culture, the first integrated air-defence system - and the direct cause of the Royal Air Force, created in April 1918 explicitly because of what the Gothas had shown. Every argument about bombing cities for the next century footnotes the summer of 1917.[2]
The word outlived the machine: for a generation of Britons 'Gotha' meant bomber the way 'Zeppelin' had meant airship. Britain's air-defence response to the raids reshaped its air power more than the raids themselves ever did.[2]
No complete original Gotha G.IV survives anywhere in the world; only fragments and a partial fuselage remain in museum storage, and no flying reproduction currently exists.

3 notable events involving the Gotha G.IV, 1917 to 1917. 5 deaths are recorded across the 2 of these with a figure listed. Curated rather than exhaustive.
A Gotha G.IV made a forced landing in the Netherlands after a propeller failure, then crashed on its first test flight after repair.
During the 'First Battle of Britain' daylight raid, a Gotha G.IV was shot down by a Sopwith Camel pilot near Manston after its engine caught fire and the aircraft broke apart in the air. All three crew were killed.
On the same raid, a second Gotha G.IV was shot down and crashed into the sea off Margate. Two crew were killed and the gunner was rescued and taken prisoner.
| G.IV | The definitive production version featuring the ventral 'tunnel' gun position that eliminated the rear blind spot of earlier Gothas. |
| G.V | Refined successor with a strengthened fuselage structure and improved nacelles, used alongside the G.IV through 1918. |
