W.27 / W.32
Таинственный самолет W 27 отличался I-образными межкрыльевыми стойками и двигателем Бенц Bz.III (195 л. с.). W 32 был похож на тот же W 27, но оснащался двигателем Мерседес D.III (160 л. с).

Brandenburg W 27
A development of the W 12, the W 27 did not differ drastically from the earlier machine; most noticeable variation was the "I"-type interplane and centre-section struts. Only a single aircraft was built, No. 2202, and it was powered with the comparatively new 195 h.p. Benz Bz IIIb engine, an eight-cylinder vee type. The performance did not warrant a production order, and the W 27 finished its days on training duties. Engine, 195 h.p. Benz IIIb. Span, 11.2 m. (36 ft. 9 in.). Length, 9.23 m. (30 ft. 3 1/2 in.). Height, 3.057 m. (10 ft. 0 1/4 in.). Area, 36.06 sq.m. (389 sq.ft.). Weights: Empty, 1,109 kg. (2,440 lb.). Loaded, 1,619 kg. (3,562 lb.). Armament, one Parabellum and two Spandau machine-guns.
Brandenburg W 32
A still further development of the W 12 two-seat patrol fighter theme was the W 32, in effect a re-engined W 27. Five machines were originally scheduled: Nos. 2282-2286, but No. 2285 and No. 2286 were cancelled in April 1918. Engine, 160 h.p. Mercedes D III. Span, 11.2 m . (36 ft. 9 in.). Length, 9.23 m. (30 ft. 3 1/2 in.). Height, 3.25 m. (10 ft. 7 7/8 in.). Area, 36.06 sq.m. (389 sq.ft.). Weights: Empty, 1,063 kg. (2,339 lb.). Loaded, 1,544 kg. (3,397 lb.). Climb, 1,000 m. (3,280 ft.) in 11.6 min. Armament, one Parabellum and two Spandau machine-guns.

BRANDENBURG W 27 & W 32 Germany
Early in 1918, it was suggested to Ernst Heinkel that a successor to the W 12 two-seat fighter would soon be required if the German Navy was to maintain its superiority over Allied types being encountered over the North Sea. To conserve valuable time, Heinkel installed the new 195 hp Benz Bz IIIbo eight-cylinder Vee engine in a modified W 12 airframe and a 160 hp Mercedes D IIIa in a second W12. Wing span and gap were reduced, stagger was increased to improve visibility, and aerofoil-section I-type interplane struts were adopted. Armament comprised two synchronised 7,92-mm LMG 08/15 machine guns and one 7,92-mm Parabellum on a flexible mount in the rear cockpit. The Benz-engined prototype received the designation W 27 while that powered by the Mercedes engine became the W 32, but both were found inferior to the W 29 monoplane and no further development was undertaken. The following data relate to the W 27.
