![]() Sikorsky S-37-1 AIA in Lima Perú R1283
First selling for $15,955, R1283 was modified as a sixteen passenger with 525hp P&W Hornet engines (the Jupiters went to S-37-B) for service in South America. It was scrapped by PAA in 1930.
The 1927 S-37-2 NX3698 (ATC 2-170) was built under a contract from Consolidated Co as their Model 12, for Army evaluation as five-place XP-496 bomber with two 525hp P&W R-1690 engines.
Sikorsky amended the suffix to "-B," but while in the service it never did get an official Army designation.

It did not meet Consolidated's requirements, either, and was rebuilt in 1929 by Sikorsky from eight passenger to 21 passenger transport with two 675hp P&W Hornets, which were replaced by the Jupiters from the S-37-1.
![]() Sikorsky S-37-B
Rebuilt again and re-registered in 1934 as NR942M, it crashed at sea in 1934.
