Key Details
Official Description
The U.S. Navy is pursuing enhancements to the performance, range, and tactical flexibility of existing 10-inch rocket motor systems. A key enabler of this objective is the maturation and application of HLG propulsion technology. HLG designs maximize total impulse within volume-constrained tactical solid propellant systems while enabling adaptable thrust-time profiles, including boost-sustain variants.

DIRECT TO PHASE II: Extended Range 10-inch Air Launched Rocket
Q1 received a detailed answer clarifying: (1) focus is grain design, not propellant development; (2) variable throttling is not required; (3) system must reach higher operating temperatures—122°F upper bound is unacceptable for usage and aging. Q2 and Q3 remain unanswered.
DIRECT TO PHASE II: Extended Range 10-inch Air Launched Rocket
Added new Q1 on propellant flexibility: clarifies that AP/Al/HTPB combination is not required if alternatives offer longer duration and variable throttling; confirms 50°C upper temperature bound is acceptable if alternative achieves >30% range improvement and throttling capability.
DIRECT TO PHASE II: Extended Range 10-inch Air Launched Rocket
Q1 received an answer clarifying that the 10-inch tactical casing design requires a metallic case based on the existing HARM structure, with the goal of demonstrating a propulsion solution.
DIRECT TO PHASE II: Extended Range 10-inch Air Launched Rocket
# Summary This Q&A addresses technical specifications for a weapons casing design, clarifying whether a 10-inch diameter tactical casing with boat-tail geometry based on HARM missile aft-end structure requires metallic materials.
