Fokker-Atlantic Y1C-14 & Y1C-15

The Y1C-14 & Y1C-15 are military versions of the civilian F-14.

The Y1C-14 was used for cargo, skydiving and other military duties of the USAAC.

20 Y1C-14s were built, some of which were later modified and given a different type of designation.

All Y1C-14s have been used by the USAAC since 1931.

Some Y1C-14s were later designated as type C-14.

As standard, the Y1C-14 flew with one Wright Cyclone R-1750-3 engine of 525 hp.

The Y1C-15 was a re-engined version with a 575 hp (429 kW) Wright R-1820 Cyclone engine, this was later designated C-15.
