The God of the Sea’s Namesake
The Lockheed Neptune was the first U.S. aircraft designed from the outset for the land-based maritime patrol role, and it was the first U.S. Navy aircraft that could carry a nuclear weapon.1 All previous U.S. land-based maritime patrol aircraft were adapted from bomber or transport designs. Among them were Lockheed’s highly successful PBO-1 Hudson and PV-series Harpoon and Ventura aircraft. Those planes—flown by Navy and Marine Corps pilots—made major contributions to Allied victory in the Atlantic and Pacific during World War II. The Neptune was a natural progression from the twin-engine PV series.
