Sikorsky JRS-1

---

In 1935 Sikorsky produced a 15 passenger flying boat called the S-43, which soon went into service with a number of civilian airlines. The U.S. Navy/Marines acquired 17 of these flying boats under the designation JRS-1, and the USAAC acquired 6 examples (most under the designation Y1OA-8). All of the Army, Navy, and Marine aircraft remained in service throughout World War II.
