The U.S. Navy has unveiled its next-generation modular missile program, announced at the Surface Navy Association national symposium on January 13, 2026. This initiative is designed to modernize the legacy Mk 41 Vertical Launch System (VLS) with dual- and quad-packing configurations for enhanced hypersonic strike, air defense, and long-range capabilities. Supporting this effort, Northrop Grumman recently secured a $94.3 million contract for the development of 21-inch solid rocket motors, which are intended to significantly boost the range and speed of the SM-6 missile family against threats traveling over Mach 5.
Key Findings
- The U.S. Navy introduced its next-generation modular missile program at the Surface Navy Association national symposium on January 13, 2026.
- The initiative is designed to optimize legacy Mk 41 vertical launch systems (VLS) for hypersonic strike, air defense, and long-range missions through dual- and quad-packing configurations.
- Northrop Grumman was awarded a $94.3 million contract on January 7, 2026, for the development and production of 21-inch solid rocket motors.
- These new motors are intended to extend the range and speed of the SM-6 missile family against threats traveling over Mach 5.
- The program emphasizes adapting existing infrastructure to enable rapid system upgrades and facilitate industry competition by funding subsystems separately.
Modular Missile Program Announcement
RAdm. Derek Trinque, Director of the Surface Warfare Development Office, announced the U.S. Navy’s next-generation missile program at the 38th Surface Navy Association national symposium on January 13, 2026. The initiative utilizes modular propulsion to develop successors to the Standard Missile series. It features a common third-stage interceptor paired with variable propulsion stacks for hypersonic strike, long-range offensive counter-air, and air/missile defense missions. This design optimizes Mk 41 vertical launching system cell capacity, enabling dual- and quad-packing configurations. The adaptation of legacy infrastructure allows for addressing emerging threats from Russia and China without requiring entirely new system designs.

Northrop Grumman Contract Details
The U.S. Navy awarded Northrop Grumman a $94.3 million contract on January 7, 2026, for designing, qualifying, and producing 60 units of a 21-inch second-stage solid rocket motor at its Elkton, Maryland Propulsion Innovation Center. This motor is intended to increase the SM-6 family’s range and speed against hypersonic, air, and surface threats. It will support the SM-6 Block IB variant with a full-diameter second stage, providing 2.4 times more propellant volume than the current 13.5-inch sustainer. Raytheon remains the SM-6 prime contractor, focusing on multi-mission integration; the Navy is funding subsystems separately to facilitate industry competition.
Addressing Hypersonic Capability Challenges
Threats from China and Russia are hypersonic, traveling beyond Mach 5 with mid-flight maneuvers. These capabilities challenge current SM-6 systems, which rely on a 21-inch booster and smaller sustainer. The modular “open system architecture” is designed to be scalable, ranging from Evolved SeaSparrow Missile envelopes to SM-6, allowing for full-size stacks for long-range roles and smaller packs for high-capacity defense. RAdm. Trinque stated, “We have to continue building not just better missiles, but finding better ways to use our vertical launchers.” Northrop’s Gordon LoPresti emphasized the low-risk, rapid design for hypersonic defense across ship and land platforms. This focus on efficiency supports deterrence amid Indo-Pacific tensions.

Program Impact and Strategy
In the short-term, the program is expected to extend the SM-6 battlespace and terminal energy against maneuvering hypersonics, facilitating rapid deployment without requiring new ship designs. Long-term, the modular propulsion is intended to serve as a building block for future Mk 41 weapons and advanced interceptors. The contract is anticipated to support manufacturing in Maryland’s Elkton community and demonstrate the U.S. commitment to defense modernization. The decoupling of subsystems is intended to foster industry competition, allowing Northrop’s motor to be scaled beyond Raytheon programs and increasing VLS capacity for Navy fleet commanders.
Readiness and Review
The contract scope includes design, production, static firings, and environmental trials required for operational qualification. SM-6 deliveries are reported to be exceeding contract schedules, contributing to accelerated readiness. The Congressional Research Service has described the SM-6 Block IB’s potential for offensive and defensive capabilities. Defense analysts have noted the advantages of propulsion upgrades over full system redesigns, though related Conventional Prompt Strike testing has indicated data gaps. The program prioritizes rapid, cost-effective defense capability to meet current strategic requirements.
