NACA Lewis Laboratory presented ARDC with results of air-breathing nuclear propulsion systems for manned applications, leading to AEC-AF Pluto project, and also initiated comparison of nuclear rocket with chemical systems for ICBM, a concept of use to Rover program. Laboratory device for simulating reentry of satellites into the earth's atmosphere were first suggested by NACA Ames Laboratory scientist Eggers (Report No. RM-A55115). Transistorized automatic pilot developed for USAF by Bendix Aviation.

Concept of nuclear reactor facility at Plum Brook proposed by NACA Lewis Research Center, construction of which was completed in 1901.

Army Ordnance ordered Jet Propulsion Laboratory to undertake research and development of Sergeant solid-propellant, surface-to-surface missile.

During 1955-56: NACA developed materials research for high-temperature jets and other structures at hypersonic speeds under direction of Robert R. Gilruth, which confirmed Redstone Arsenal's contention that ablation was sound heat protection method for reentry of nose cones and capsules.

During 1955-58: NACA laboratories completed basic aeronautical research supporting feasibility of B-70 supersonic bomber.

During Fall: Capt. Grover J. D. Schock of USAF Aeromedical Laboratory conducted subgravity flight program (Task 78501) with F-940 aircraft at Wright-Patterson AFB.
