Dolphin

The Douglas Dolphin was a versatile amphibious transport aircraft developed by the Douglas Aircraft Company in the early 1930s. First flown in 1931, the Dolphin stemmed from the company's interest in creating a luxury flying‑boat that could also serve military purposes. It featured a high‑mounted, all‑metal wing, a streamlined hull with retractable landing gear, and two radial engines mounted on the wing leading edges, providing reliable power for water and runway operations. The cabin accommodated up to eight passengers or a small crew, and a later version incorporated a spacious cabin for VIP and executive transport, often fitted with sleeping berths and a galley. Over 200 Dolphins were built for a range of customers, including the United States Navy, which designated the type as the R2D and employed it for patrol, rescue, and liaison duties. Its ability to operate from both sea and land made it a valuable asset in remote regions and during World War II, where it supported transport and search‑and‑rescue missions. The Dolphin’s innovative hull‑design and dual‑mode capability helped pave the way for later amphibious aircraft, cementing its place as a noteworthy milestone in early aviation history.
