Under a new serial system this Flying Life Boat became V115 in October 1934, shortly before CGAS Salem opened. From 1933 to 1936, the Coast Guard's aircraft also wore names of stars, and the absence of its name Arcturus would date this photo from 1936. The type was retired in August 1941.

The Atlantic Fokker company became the General Aviation division of GM - later North American. Its (A)F-15 became the GA-15, designated FLB (Flying Life Boat) by the USCG and then PJ in the US Navy designation system. Five machines built from 1931, the first of which was converted to tractor propulsion as the PJ-2. USCG s/n 254 Amacar, s/n 255 Arcturus and the Douglas RD-1 Dolphin s/n 128 Sirius were based at Dinner Key in 1934. Photo from: US Coast Guard
