Brandenburg W 20
  This little single-seat flying-boat was designed during 1917 for carrying aboard U-boats. It could be dismantled in 1 3/4 min. and stowed into space measuring only 20 ft. X 6 ft.; re-assembly took 2 3/4 min. As the type of submarine for which it was intended never went into service, only three examples of the W 20 were built. The first, No. 1551, had no interplane struts; these members were, however, added to the structure of Nos. 1552-1553, which also had the lower wing increased in span. Engine, 80 h.p. Oberursel UO. Span, 5.8 m. (19 ft. 0 3/8 in.), "1551"; 6.8 m. (22 ft. 3 3/4 in.), "1552/3". Length, 5.91 m. (19 ft. 4 5/8 in.), "1551"; 5.925 m. (19 ft. 5 1/8 in.), "1552/3". Area, 14.95 sq.m. (161 sq.ft.), "1551"; 15.82 sq.m. (171 sq.ft.), "1552/3". Weights: Empty, 396 kg. (871 lb.). Loaded, 568 kg. (1,250 lb.). Climb, 1,000 m. (3,280 ft.) in 14.9 min. Duration, 1 1/4 hr. Armament, none.

Three examples of the Brandenburg W20 single-seat flying-boat were built, the so-called 'type' aircraft which was the example of any new design evaluated by the seaplane experimental centre (SVK) at Warnemunde before being accepted for naval use (by the SAK). 1552 is seen on 14 March 1918. Intended to be carried as an aerial scout on submarines, it did not see operational service. The W20 was designed to be assembled and dismantled very quickly, using the minimum of hand tools; individual components were stowed in watertight air tubes on the submarine's deck.
