Gotha G VII (prototype)
  During 1918, Gotha developed the twin-engined machine into a smaller, lighter aircraft intended mainly for ultra-long-range photo-reconnaissance duty. Later in the year special units were formed, Reihenbihlzug (Photographic Section), whose establishment consisted of four aircraft. See Gotha G VII (Production) for continuation.

Gotha G VII (production)
  As may be seen, the production aircraft bore little resemblance to the prototype G VII. Additional interplane struts were added; there were ailerons at all four wingtips with improved balances; a compound tail nit was incorporated and the wings were slightly swept to compensate the "sawn-off" nose. With the accent on speed, forward armament was deleted, and the consequent shortened nose enabled the engines to be placed closer together, thereby improving asymmetric power characteristics. Engines, two 260 h.p. Mercedes D IVa. Span, 19.27 m. (63 ft. 2 3/4 in.), length. 9.63 m. (31 ft. 7 1/8 in.). Area, 63.8 sq.m. (689 sq.ft.). Weights: Empty, 2,419 kg. (5,322 lb.). Loaded, 3,139 kg. (6,906 lb.). Speed, 180 km.hr. (112.3 m.p.h.). Climb. 6,000 m. (19,680 ft.) in 38 min. Duration. 3 hr. Armament, one Parabellum machine-gun in dorsal position.


Gotha G VIII
  Further development of the short-nose twins resulted in the G VIII, which may be seen to resemble the prototype G VII except for the wings of noticeably increased span. A lightened version, designated GL VIII, had a compound tail assembly and auxiliary struts bracing the upper wingtips. Engines, two 245 h.p. Maybach Mb IV. Span, 21.73 m. (71 ft. 3 5/8 in.). Length, 9.79 m. (32 ft. 1 1/2 in.). Height, 3.51 m. (11 ft. 6 1/4 in.). Area, 79 sq.m. (861 sq.ft.). Weights: Empty, 2,676 kg. (5,887 lb.). Loaded, 3,706 kg. (8,153 lb.). Speed, 180 km.hr. (112.5 m.p.h.).

AVIATIK "MILESTONES"

  In addition to their single-seaters and two-seaters, the Aviatik firm have also built several large machines (Riesenflugzeug), illustrations of three of which are published herewith.

The Aviatik, Type Go. G VII
  built in 1918, is a twin-engined machine of the bomber type. It was fitted with two 200 h.p. Benz engines placed on the wings in short engine nacelles. The radiators were in the nose of these nacelles. From the photograph it will be noticed that the two engine nacelles are placed comparatively close to the main fuselage, the nose of which is very short, allowing the tractor airscrew blades to pass in front of it. This arrangement of the engines has brought about a somewhat unusual strutting arrangement, as regards the inner cellule, at any rate. The tail is of the biplane type, with three rudders.

Too late to take an active part in combat, the 3-man Gotha G VII bomber/long range reconnaissance type of mid-1918 had a top level speed of 112mph thanks to its twin 260hp Maybach Mb IVa engines. The G VII's operational ceiling was 19,685 feet, while the range, with bomb load, of 335 miles was clearly capable of significant extension for photo-reconnaissance work. Plans had been put underway to build this type in quantity, with contracts placed with Gotha for 55, plus a further 100 from Aviatik in Leipzig. As it was, only 11 had been completed at the time of the Armistice, three of which found their way into Soviet hands.

A developed version, the Gotha G VIII, similar in all major aspects except for a longer span top wing to further increase climb and improve high altitude handling, had flown prior to war's end.
