Abstract : Future tactical and defensive missile propulsion systems must provide a high degree of mission versatility and robustness at low cost with minimum development risk. The Navy's Standard Missile has successfully demonstrated an evolutionary philosophy of guidance and propulsion upgrades over its long operational history. Replacing the existing 13.5-in diameter Mk 104 Dual Thrust Rocket Motor (DTRM) with a full 21 -in. diameter high performance motor offers increased propulsion capability and weapon system options. An improved performance stage-two motor, consistent with the Mk 72 booster's 21-in. diameter, provides an upgraded missile system with expanded range, greater throw weight and higher velocity increments. Expanded propulsion capability can be achieved with low development risk commensurate with improvements in the Vertical Launch System (VLS) Canister. Pratt & Whitney's Chemical Systems Division, currently manufacturing the Standard Missile 2 Extended Range Block IV (SM2-ER Blk IVA) Mk 72 booster, has established an improved stage-two motor approach. The benefits of this upgraded full caliber motor compatible with the existing Mk 72 booster and VLS interfaces is presented.
