P.Bowers Curtiss Aircraft 1907-1947 (Putnam)

R-3 - Two R-3s delivered to the US Navy in 1916 were fitted with twin floats and 160 hp Curtiss V-x engines, Generally similar to the production R-2s, the R-3s had their wing spans increased to 57 ft 1 1/32 in (17,39 m) by the addition of a longer-span centre section for the upper wing and the insertion of extra panels on each side of the fuselage inboard of the standard-length outboard lower wing panels in the manner of the N-9. The wings were rigged without dihedral.
   The original Navy identification/serial numbers for its two R-3s were AH-62 and AH-65 in the system adopted in March 1914; after 18 May, 1917, these became A66 and A67 in the new sequential serial number system and operated under their Curtiss model designations.
   Eighteen R-3s were ordered by the US Army in 1916 for delivery in 1917, but these appear to have been completed as improved R-6s and R-9s.

R-3
   R-3 - Observation seaplane. Pilot and observer. 160 hp Curtiss V-X.
   Span 57 ft 1 1/32 in. (17,39m); length 30 ft 11 1/2 in (9,43 m); wing area 609,7 sq ft (56,64 sq m).
   Empty weight 3,000 Ib (1,361 kg); gross weight 3,837 lb (1,740 kg).

R-6 (Model 2A) - The R-6 of early 1917 was a long-wing seaplane like the R-3 and differed from it mainly in use of the 200 hp V-2-3 engine and three degrees of dihedral in the outer wing panels. All but one of the seventy-six R-6s delivered to the US Navy had twin floats, serial number A193 being fitted with a single float. Army R-6s were delivered both as landplanes and as twin-float seaplanes. The US Army ordered 18, but most are believed to have been released to the Navy before Army acceptance.
   Navy R-6s became the first American-built aeroplanes to serve US forces overseas in World War I when a squadron was assigned to patrol duty in the Azores in January 1918. Average cost of the R-6 and similar R-9 was $15,200 less GFE.
   US Navy serial numbers; A162/197 (36), A302/34I (40). US Army serial numbers; 504/521

R-6L - Forty of the Navy's R-6s were converted to R-6L in 1918 by the installation of 360 hp low-compression Liberty engines in the manner of the R-4Ls of the Army. R-6Ls were used for the renewal of Navy torpedo-dropping experiments in 1920 and a number as Service torpedo aircraft until replaced by later equipment. The last R-6Ls were condemned in 1926. An additional fourteen R-6Ls were created by converting the R-9s with serial numbers A919, 920, 925, 943, 956, 958, 963/966, 970, 976, 991, and 994 to R-6 configuration.

R-6L
   Observation and torpedo seaplane. Pilot and observer. 360 hp Liberty.
   Span 57 ft 1 3/16 in (17,4 m); length 33 ft 5 in (10,18 m); height 14 ft 2 1/32 in (4,31 m); wing area 613 sq ft (56,94 sq m).
   Empty weight 3,513 lb (1,593 kg); gross weight 4,634 lb (2,102 kg), or 5,662 lb (2,568 kg) with torpedo.
   Maximum speed 100 mph (160,93 km/h); climb in 10 min - 6,000 ft (1,829 m); service ceiling 12,200 ft (3,718 m): range 565 miles (909 km).
   Armament - one 1,036 lb (470 kg) torpedo.

R-9 - The R-9 airframes for the Navy were bomber versions of the R-6 with the controls rearranged to place the pilot in the front seat and the observer/bombardier in the rear. Ten (A883/887, A901/905) were transferred to the US Army in February 1918.
   US Navy serial numbers: A873/984 (112). US Army serial numbers: 39033/39042 (10)
