US Army Air Defense Shifts to Multi-Interceptor Systems

"We have the capabilities we need to have to fight and win, but it’s our job to ensure that victory is achievable in the future inside of any dynamic environment scenario fight we might find ourselves in," Army Lt. Gen. Frank Lozano said during a panel at the Association of the U.S. Army convention.

Lt. Gen. Frank Lozano: diversify interceptors and speed decisions

Lozano, the Army’s Portfolio Acquisition Executive for Fires, framed the service’s shift away from single-interceptor dependency as a matter of sustainment and resiliency. He said the Army remains committed to buying more PAC-3 Missile Segment Enhancement (MSE) missiles — the program goal being "to get to 2,000 [per year]" — but that simply buying more of a single great missile is not sufficient when planning for larger production scales such as 4,000, 6,000 or 8,000 rounds. He argued for a "diverse set of capabilities" and for shorter, more aggressive acquisition timelines, proposing 24- or 36-month options and in-parallel "shoot-off" competitions to get new capability into the field sooner.

Five named Army interceptor programs and what each seeks

• Low Cost Interceptor (LCI): Seeks a lower-cost, lower-tier interceptor for Patriot with a unit price target "no more than $1 million." Lozano said LCI uniquely solicits both complete all-up rounds and component-level offers to enable competitive teams of integrators and suppliers.
• Next-Generation Short-Range Interceptor (NGSRI): Intended as a Stinger replacement, NGSRI must be compatible with vehicle-based and man-portable launchers. Lockheed Martin and Raytheon have been competing; a shoot-off is planned in the fourth quarter of Fiscal Year 2027.
• Next-Generation C-UAS Missile (NGCM): The Army is pursuing a counter-drone interceptor to be integrated into launchers already used for the Coyote interceptor. AeroVironment’s Freedom Eagle-1 (FE-1) was previously selected; the service issued a request for information in August and plans an initial evaluation in Q4 FY27 followed by a deeper operational assessment in FY28.
• Second Interceptor (for Enduring Shield / IFPC Inc 2): Focused on improved capability against incoming cruise missiles relative to the AIM-9X. Lockheed Martin and Boeing (teaming with Anduril) remain competitors; the Army moved into phase two and will hold an in-parallel shoot-off in Q4 FY27, open to additional firms that continued investing in the capability.
• Future Interceptor (for Patriot): Aimed at a new interceptor with improved capabilities against hypersonic and other upper-tier threats.

Patriot, Enduring Shield, and current stockpile choices

The Army’s main ground-based systems historically fielded single interceptor types; Patriot had increasingly relied on the PAC-3 MSE while production of the preceding PAC-3 Cost Reduction Initiative (CRI) ended in 2023. Earlier in 2026 the Army placed its first order in decades for PAC-2 Guidance Enhanced Missile-Tactical (GEM-T) missiles for Patriot, a return to an older interceptor design. Separately, the new middle-tier Enduring Shield system is being fielded capable of multiple interceptor types but is currently only being acquired with AIM-9X Sidewinders loaded into it — a capability the Second Interceptor effort is explicitly intended to supplement and enhance, especially against cruise-missile threats.

Competition, supply chains, and cross-service parallels

The Army’s approach emphasizes multiple suppliers and new entrants. Examples named in the current effort include Lockheed Martin, Boeing teamed with Anduril, Raytheon, and AeroVironment. Lozano noted a desire to "thicken our inventory with low-cost, affordable munitions" and to produce both all-up rounds and component-level offerings to broaden the supplier base. The Pentagon has also pursued similar strategies elsewhere: the Navy’s Naval Modular Missile (NMM) program envisions a family of sea-launched missiles sharing common components, and the Department of War announced framework agreements in May aimed at bringing disruptive new entrants into lower-cost cruise and hypersonic missile production.

What this means for procurement leaders, technologists, and warfighters

• Procurement leaders: Expect parallel competitions, shorter demonstration timelines, and explicit solicitations for component-level offers to create alternate supply lines and make replenishment more viable if sustained combat expenditures rise.
• Technologists and integration teams: Will need to design for modularity and common launch architectures — examples include containerized options and the Common Autonomous Multi-Domain Launcher (CAML) concept, which emphasizes autonomy and the ability to fire a range of surface-to-air and surface-to-surface munitions.
• Warfighters and sustainment planners: Should prepare for mixed loadouts that combine higher-end interceptors with lower-cost options to manage cost-per-engagement and replenish stocks more quickly when conflicts draw out; Lozano stressed the objective is not to eliminate exquisite munitions but to create an "affordable, complementary mix."

Operational drivers are explicit: the war with Iran, other Middle East crises, and the ongoing conflict in Ukraine have underscored the need for deeper stockpiles, shorter lead times and multiple suppliers. The Army’s near-term calendar reflects those priorities — planned shoot-offs for Second Interceptor and NGSRI in Q4 FY27, an NGCM initial evaluation in Q4 FY27 and assessment in FY28, and active solicitation of both full rounds and component-level offers under LCI. Lozano closed the panel by stressing delivery and programmatic success: "if we deliver on that wide variety of capability, then we can increase and ramp that capacity. And that would be my wish list, that we have enough resources and we achieve programmatic success in the way that we’re planning to, so we can deliver in mass."
