Variants
All three of the Skyrockets had 35-degree swept wings.
Until configured for air launch, NACA 143 featured a Westinghouse J-34-40 turbojet engine rated at 3,000 lbf (13 kN) static thrust. It carried 260 US gallons (980 L) of aviation gasoline and weighed 10,572 lb (4,795 kg) at takeoff.
NACA 144 (and NACA 143 after modification in 1955) was powered by an LR-8-RM-6 rocket engine rated at 6,000 pounds-force (27 kN) static thrust. Its propellants were 345 US gallons (1,310 L) of liquid oxygen and 378 US gallons (1,430 L) of diluted ethyl alcohol. In its launch configuration, it weighed 15,787 lb (7,161 kg).
NACA 145 had both an LR-8-RM-5 rocket engine rated at 6,000 lbf (27 kN) static thrust and featured a Westinghouse J-34-40 turbojet engine rated at 3,000 lbf (13 kN) static thrust. It carried 170 US gallons (640 L) of liquid oxygen, 192 US gallons (730 L) of diluted ethyl alcohol, and 260 US gallons (980 L) of aviation gasoline for a launch weight of 15,266 lb (6,925 kg).
