O.Thetford, P.Gray German Aircraft of the First World War (Putnam)


A.E.G. G IVk
  Yet another variant of the G IV. Fitted with 2 cm. Becker Cannon in an armoured nose panel, and intended for use with the Schlachtgeschwadern in 1918, it is not thought to have been used operationally. A biplane tail unit was fitted and armour plate panels also enclosed the 260 h.p. Mercedes D IVa engines. Standard G IV wing cellule of 18.4 m. (60 ft. 44 in.) was fitted. A second version with G V wing cellule (G IVk 503/18) also existed.

AEG G.IVk

  Another German armored aircraft type designed for ground-attack was the AEG G.IVk, which was developed from the standard AEG G.IV bomber. AEG G.IV G.1096/16 was armed with a 20mm Becker cannon mounted in an experimental rotating chin turret to investigate the feasibility of attacking tanks and other ground targets from the air. The field of fire was 50 degrees vertical and 90 degrees horizontal. Idflieg reported that the aircraft was slated for combat evaluation in December 1917, but further information is lacking. However, ground and air trials demonstrated that the visibility, field of fire, and target acquisition were satisfactory. The cannon installation was reported as "frontline ready", leading to the development of the specialized AEG G.IVk ground-attack aircraft.
  As a result of the progress made with G.1096/16, in March 1918 Idflieg ordered five AEG G.IVk ground-attack aircraft for service trials. Numbered G.500/18 to G.504/18, they were armed with two 20mm Becker cannons, one mounted in the lower nose turret and a second in a rear turret that allowed for firing over the fuselage or downward through a 'Gotha-type' tunnel. For defense against fighters, two Parabellum machine guns were mounted on LVG gun rings (copies of the Scarff) in the nose and rear turrets. Like the rear cannon, the rear Parabellum could also fire downward through the fuselage tunnel. Four 50 kg P.u.W. bombs could be carried under the fuselage. Four vertical magazines in the front cockpit and three in the rear held 12.5 kg P.u.W. fragmentation bombs. Chrome-nickel steel armor plating 5 mm thick covered the floor and sides of the fuselage, extending from the nose around the rear gunner's cockpit. The engine nacelles were armored as well.
  Flight trials of the prototype, G.500/18, in February 1918 demonstrated good results but the biplane tail and armor plating required minor changes. The cannon firing trials performed in April 1918 were satisfactory. Though dispatched to the front in October-November 1918, it is not known if the G.IVk saw operational service. As part of the Armistice stipulations, the Germans turned over the four production AEG G.IVk ground-attack aircraft (G.501/18 - G.504/18) to the British in January 1919.

The AEG G.IVk, the 'k' suffix for 'Kanon', was an armored development of the G.IV for antitank duties. The cockpits and both engines were armored against rifle and machine-gun fire to survive at low altitude while hunting tanks. The front and rear gunners each had a flexible 20mm Becker cannon that could fire downward at ground targets plus an upward-firing machine gun to defend against fighter attacks. A 'box' tail with twin fins and rudders was fitted to improve control in case of an engine failure. Five of these were turned over as part of the armistice terms; it is not known if they arrived in time for combat operations.

The prototype AEG G.IVk was G.500/18 shown here on the AEG factory airfield at Henningsdorf. The four production aircraft had a different tail design. G.500/18 wears an interesting camouflage of two-color sprayed camouflage on the fuselage, dark engine nacelles, and printed camouflage fabric on the fins and rudders. The 20mm Becker cannon in the nose mounting is prominent. This aircraft was dispatched to the front for operational use in October-November 1918, but it is not known if it was used in combat.

The AEG G.IVk G.503/18 was one of the four production G.IVk ground-attack aircraft turned over to the British according to the terms of the armistice. The vertical tail surfaces of the four production machines differed from the prototype. The aft gunner could fire his 20mm Becker cannon conventionally to the sides or down through the fuselage in a Gotha-like tunnel, and could do the same with his machine gun.The forward gunner had a forward-firing 20mm Becker cannon for anti-tank duties and a flexible machine gun to defend against fighter attack. No conventional bomb bay was fitted but the AEG G.IVk had four vertical tubes about two feet long mounted in the front cockpit and three in the rear cockpit. These tubes were perhaps intended for launching flares or special anti-tank bombs that Idflieg had developed.

The rear gunner of the AEG G.IVk in his turret handling his 20mm Becker cannon. Although no bomb bay was fitted and supposedly no bomb racks, bombs can be seen underneath his position. He could fire both his cannon and machine gun to the sides and downward through a Gotha-style tunnel through the fuselage.

An Australian soldier pokes his head our of the nose turret of the AEG G.IVk; another stands in the cockpit. The armor plate was difficult to form, so all armor on the aircraft was either a flat plate or a simple curve. Compound curves were simply too difficult to form at the time.

Tightly squeezed into an experimental turret, the gunner demonstrates the operation of a 2 cm Becker cannon mounted in the AEG G.IV 1096/16 bomber. Effective firing trials against ground targets were performed in October-November 1917. The turret was capable of rotation. The curious, heart-shaped machine gun support on the upper turret is likewise an experimental installation.
