Albatros C XIII
  Built in 1917, the C XIII was an endeavour to develop quickly a CL aircraft from the D Va. Only one was built and, as may be seen, it was little more than an enlarged version of the D Va. Certainly it was an elegant two-seater. Engine, 160 h.p. Mercedes D III. Span, 100 m. (32 ft. 9 3/4 in.). Length, 7.8 m. (25 ft. 7 1/8 in.). Height, 2.71 m. (8 ft. 10 3/4 in.). Weights: Empty, 700 kg. (1,540 lb.). Loaded, 1,060 kg. (2,332 lb.). Speed, 165 km.hr. (103.12 m.p.h.). Climb, 1,000 m. (3,280 ft.) in 4 min., 5,000 m. (16,400 ft.) in 47 min. Duration, 2.5 hr. Armament, one Spandau and one Parabellum machine-gun.

Albatros C.XIII

  After the failure of the Albatros C.IX to reach production for the light C-type role, Albatros created another design to the same Idflieg specification. The resulting C.XIII, had a single-bay configuration like the C.IX and, obviously based on the Albatros D.V fighter, was intended for the CL-role. A compact, streamlined aircraft, it was powered by the same 160 hp Mercedes D.III used in the D.V fighter and earlier C.IX prototype. The cockpits were very close for crew coordination. Unfortunately, the C.XIII retained the single-spar lower wing already proved structurally unsatisfactory in the Albatros D.V. Armament was the standard German two-seater fit of a fixed Spandau machine gun for the pilot and a flexible Parabellum machine gun for the observer.
  Normally Idflieg would order three examples of a new prototype. However, only a single C.XIII was apparently built.
  Albatros' second attempt at a light C-type, the C.XIII, was more convincing than its C.IX. It was more refined, with no protrusions, and was much lighter than the C.IX or Hannover. It looked aggressive, and, except for high-altitude climb rate, its performance matched the Hannover. However, to achieve its light weight the C.XIII retained the single-spar lower wing of the D.V, so undoubtedly inherited its structural weakness, whereas the Hannover was a very robust design. Furthermore, the C.XIII may not have matched the Hannover's excellent maneuverability. With a more robust two-spar lower wing like that of the Pfalz D.III, the C.XIII might have been competitive.


The excellent Hannover CL.II was placed in production. It had better speed and climb than the Albatros C.IX and was also noted for its maneuverability, something the C.IX was unlikely to have matched. The Albatros C.XIII fared better in comparison but had a single-spar lower wing that caused structural problems in Albatros fighters.

Colorized photo of the Albatros C.XIII prototype. The streamlined C.XIII was obviously derived from the Albatros D.V fighter. It was much lighter and more compact than the earlier C.IX and was a more convincing design. Although its performance matched the competing Hannover CL.II, it may not have matched the Hannover's excellent maneuverability. Moreover, limited by its single-spar lower wing that had already suffered structural failures in the Albatros D.V, the C.XIII clearly lacked the Hannover's robustness, an essential quality for a successful combat aircraft.
