ABL X-248

The X-248 was a solid rocket motor from Hercules–Allegany Ballistics Laboratory, used in early upper-stage applications. NASA Langley identifies its propellant as cast double-base with 3% aluminum and documents how motor performance could vary under spin. The laboratory designation distinguishes this historical motor from ABL Space Systems’ much later E2 liquid-engine family.

    Note
    NASA Langley’s report identifies the Hercules–Allegany Ballistics Laboratory X-248 and its cast double-base propellant containing 3% aluminum, discusses spin sensitivity, and cites manufacturer testing in support of Javelin. These are motor-specific identity and propellant details; no universal thrust rating is inferred from a spin test.
