This is one of Robert H. Goddard's P-series rockets, probably the one he used for a test in October 1941 during which the rocket jammed in the launch tower and failed to lift. Goddard's P-series was so designated because they contained his propellant pumps. The series was also his largest and last liquid-fuel flight rockets and were tested at Roswell, New Mexico, during 1938-1941.
However, only two P-series rockets achieved flight. But the tests were discontinued because Goddard moved in 1942 to Annapolis, Maryland to undertake wartime work for the Navy on non-flight rocket motors. This rocket was donated to the Smithsonian by the Daniel and Florence Guggenheim Foundation for the Promotion of Aeronautics in 1985.
