Interceptor

The U.S. Army now has at least five named programs seeking new anti-air interceptors of various tiers to collectively address everything from advanced hypersonic missiles to small weaponized drones. In the process, an important central theme is emerging: the service’s days of fielding air defense systems that can only use one type of interceptor look to be increasingly over. For the U.S. military, the impacts from the war with Iran have made clear that diversifying munitions stockpiles and supplier bases is no longer just valuable, it is critical.

Army Lt. Gen. Frank Lozano, the service’s Portfolio Acquisition Executive for Fires, highlighted this growing trend yesterday during a panel discussion at the Association of the U.S. Army’s (AUSA) main annual convention, at which TWZ has been in attendance.

To provide some immediate context, with the exception of Patriot, the main ground-based air defense systems in Army inventory today are fielded with just one type of interceptor. In the case of Patriot, the service’s procurement of new interceptors had also been increasingly limited to just one type, the PAC-3 Missile Segment Enhancement (MSE). Production of the preceding PAC-3 Cost Reduction Initiative (CRI) missile ended in 2023. Just earlier this year, the Army placed its first order in decades for new PAC-2 Guidance Enhanced Missile-Tactical (GEM-T) missiles, an older interceptor design for Patriot that has remained in production primarily for U.S. allies and partners.

Separately, the Army is in the process of fielding Enduring Shield, a new middle-tier air defense system designed to handle multiple interceptor types. However, the service is currently only acquiring AIM-9X Sidewinders to load into them. We will come back to this later on.

“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,” Lt. Gen. Lozano said yesterday. “So, it’s incumbent upon Mr. Ingraham [Assistant Secretary of the Army for Acquisition, Logistics and Technology Brent Ingraham] and I to continue to be creative and looking at, well, should we buy GEM-Ts because they’re being produced?”

“GEM-Ts are a really good missile in the battlespace within they operate. I mean, they’re being employed today by air defense brigades around the world,” he continued. “So if we have the opportunity, it’s probably something we should take advantage of, and we’re looking at doing that.

“We’ve had a lot of discussions about even more interceptors. From a PAC-3 MSE perspective, our goal has always been to get to 2,000 [per year],” he added. “Why we’re running programs like LCI [Low Cost Interceptor], and NGSRI [Next-Generation Short-Range Interceptor], and NGCM [Next-Generation C-UAS Missile], and Second Interceptor, is because I think the easy button answer is just buy more of a great missile. We’re going to buy more [PAC-3 MSEs], but when we start talking about overall missile output, we start looking at numbers like is it 4,000, is it 6,000, is it 8,000, we’re looking at a diverse set of capabilities.”

The LCI program is seeking a lower-cost and lower-tier interceptor for Patriot with a unit price of no more than $1 million. PAC-3 MSE’s average unit cost has been around $4 million in recent years.

NGSRI is the Army’s program to find a replacement for the venerable Stinger. The new missiles have to be compatible with existing vehicle-based and man-portable launchers.

The Army is working to field a new counter-drone interceptor through NGCM. Those missiles will be integrated into launchers the service has now for the Coyote interceptor.

The Second Interceptor effort is for Enduring Shield, which is also known as the Indirect Fire Protection Capability Increment 2 (IFPC Inc 2). The main goal there is to provide increased capability against incoming cruise missiles compared to the AIM-9X.

There is also the Army’s Future Interceptor effort, which also came up separately at the panel yesterday, and is also for Patriot. Unlike LCI, the aim here is to acquire a new interceptor with improved capabilities against hypersonic missiles and other upper-tier threats.

Historically, Army programs like these would eventually result in the selection of a single winning missile design. Lozano’s remarks yesterday point to the service increasingly taking a very different approach.

On “second interceptor, obviously, we just moved into phase two of that program. We’ve got Lockheed Martin competing with Boeing, who was teamed with Anduril,” Lozano said. “But we wanted to turn up the heat on that program. I constantly get frustrated when a funding profile emerges over the FYDP [the Future Years Defense Program], and then magically we lay in a five-year program.”

“I’m like, no, I actually need that capability now,” he continued. “So, have we thought maybe what if we ran a 24-month program or a 36-month program, right? And so, in that vein, what we have decided to do is, while those two companies continue to compete, we’re going to create a shoot-off opportunity in [the] fourth quarter [of Fiscal Year 20]27, and I want to run an in-parallel, what I call an in-stride competition.”

“We just held an industry day, and we basically just said, hey, if there’s any other company who didn’t make the first cut in the phase one, but, oh, by the way, who continued to invest in the IFPC Second Interceptor capability, we’d love for you to come out to the range,” he added. “We’ll give you range time, we’ll present targets, and we’ll allow you to recompete with an opportunity to get back into the program folder.”

The Army is doing the exact same thing with NGSRI, where Lockheed Martin and Raytheon have been competing face-to-face. That program is also now planning to hold a new shoot-off that will be open to other vendors in the fourth quarter of Fiscal Year 2027.

There are signs the Army is moving in a similar direction with NGCM, where it previously selected AeroVironment to supply its Freedom Eagle-1 (FE-1) interceptor. The service put out a request for information seeking new NGCM options in August, with a goal of holding an initial evaluation again in the fourth quarter of Fiscal Year 2027. A deeper operational assessment could then follow in Fiscal Year 2028.

Freedom Eagle-1, the Next-Gen CUAS Missile

To reiterate, on top of all this, the Army is also now pursuing at least two new interceptor options for Patriot.

“We have to address the threat, and we need to address the threat in a complementary way, meaning we need to fight on a cost curve that’s affordable for the U.S. Army to maintain and sustain that warfighting capability abroad,” Lozano stressed yesterday.

This gets to the crux of the matter. It is not at all a new observation that just having a stockpile of any particular munition on day one of a conflict is not enough, especially if the fight becomes drawn out. There needs to be sufficient depth to those stocks at the start and the ability to readily replenish them in line with expenditures. The war with Iran, compounded by other crises in the Middle East and the ongoing conflict in Ukraine, has made clear that these core truths apply to all armed forces, even the U.S. military.

Lower-cost munitions are part of the solution, but they also need to be producible at scale on reasonable timelines. The lead time for higher-end munitions today is often measured in months, if not years. Furthermore, being locked into a single vendor has been shown to not just be undesirable, but a potential national security risk in an actual conflict. Lozano’s remarks yesterday, and how the Army is now pursuing new anti-air interceptors, reflect larger trends, not just in the acquisition of larger volumes of munitions overall, but also from a broader array of total suppliers.

There has also been a push across the U.S. military to bring in new and non-traditional firms, including in partnership with established prime contractors. An example of this is the Boeing/Anduril team-up for Second Interceptor. This was also underscored by new framework agreements the Pentagon announced back in May regarding the planned purchase of thousands of lower-cost cruise missiles.

With regard to the LCI program, specifically, Lozano highlighted an additional aspect of all of this yesterday.

LCI has “a unique twist to it because we’re looking for companies who have all-up rounds, but I’m also asking for companies to come in at the component level,” he explained. “We typically don’t do that, right? There’s a lot of risk in managing components and generating all-up round systems. But we’re also looking for weapon system integrators, because I want to be able to create two or three teams who can compete with the all-up round guys to see if we can generate some momentum behind the fact that we need to thicken our inventory with low-cost, affordable munitions.”

The U.S. Navy is now pursuing a roughly similar approach with its Naval Modular Missile (NMM) program. NMM envisions an entirely new family of sea-launched surface-to-air missiles that offer very different capabilities, but that all feature certain common components, as you can read more about here.

The Army is also eyeing a new family of launcher vehicles, as well as containerized options, all capable of firing various types of surface-to-air and surface-to-surface munitions. Autonomy is also an important aspect of what is aptly dubbed the Common Autonomous Multi-Domain Launcher (CAML) program.

It is also important to note here that the underlying aim is not to eliminate more exquisite munitions, or the capabilities that they offer, but to create a more affordable, complementary mix of options.

“What I would say is we’re solely focused on delivering on the programs we are executing now,” Lozano said in closing at the end of the panel yesterday. “We have to deliver, and 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.”

All signs point to the diversity in munitions that Lozano is talking about here being particularly pronounced in future Army air defense capabilities full of systems firing multiple types of interceptors.

Lockheed Martin has unveiled the PAC-3 Edge, a new interceptor that would represent the top tier of the U.S. Army’s Patriot air defense missile family. The missile is being developed to deliver greater performance against advanced threats than the current PAC-3 Missile Segment Enhancement (MSE), as the Army advances a competition for its next-generation interceptor.

The company says PAC-3 Edge will offer improved performance against increasingly challenging aerial threats, including advanced ballistic and hypersonic missiles. The design builds on the PAC-3 MSE’s existing technology while incorporating a new seeker, an upgraded control system, and a more advanced solid rocket motor developed with Northrop Grumman.

In terms of appearance, PAC-3 Edge differs significantly from the PAC-3 MSE. It does away entirely with the mid-body strakes. The missile body also lacks the distinctive tapered section that separates the narrower forward section from the broader rear section on the MSE version.

Lockheed announced on October 9 that it had been selected to advance to the next phase of the Army’s Future Interceptor program. Company officials said testing is expected to begin in 2027, with initial deployment targeted for 2031.

The Army’s selection of Lockheed and another unnamed competitor marks a significant development in the service’s effort to improve the Patriot system’s ability to deal with more sophisticated threats. The Army previously abandoned its Lower-Tier Future Interceptor (LTFI) program in 2024, citing cost concerns, and instead emphasized incremental improvements to the existing PAC-3 MSE. The subsequent emergence of the Future Interceptor competition points to renewed interest in a more substantial leap in capability.

A More Capable Patriot Interceptor

PAC-3 Edge is intended to preserve the advantages of the existing PAC-3 family while improving the missile’s ability to engage targets at longer ranges and higher altitudes.

One of the central changes is a new seeker being developed by Lockheed Martin’s Strigo Product Center. The company says the technology will improve target detection and tracking, helping the interceptor deal with more demanding threats. The company has not disclosed the seeker’s technical details, but one possibility is a dual-mode or multimode configuration, combining different sensing methods to improve target acquisition and tracking in challenging conditions. Such an approach could help an interceptor maintain a reliable track against maneuvering targets and better distinguish real threats from decoys or other countermeasures.

Tim Cahill, president of Missiles and Fire Control (MFC) for Lockheed Martin, told TWZ that the same seeker technology that will be used in PAC-3 Edge will also find its way into future offensive and defensive systems going into the future. “So it isn’t just a one single seeker solution, but it will be a family of seekers that will operate across a number of regimes,” Cahill explained. “Frankly, I’d like to not tell everybody exactly what we’re doing, but it is clearly different from what is out there right now,” Cahill said, adding that hardware assemblies and components are now being tested in the lab, and that seekers have been flown on aircraft testbeds.

The missile will also use a three-pulse (as opposed to two-pulse) solid rocket motor designed by Northrop Grumman. Unlike a conventional motor that provides most of its thrust in a single sustained burn, a multi-pulse design can deliver thrust at different points during flight. That can help preserve energy for the terminal engagement, when an interceptor may need to maneuver aggressively to reach a target.

Lockheed says the combination of the new seeker, propulsion system, and control system improvements will provide greater maneuverability and improve performance at extended ranges and higher altitudes. To ensure greater agility, Jason Reynolds, vice president and general manager of Integrated Air and Missile Defense (IAMD) at Lockheed Martin, explained that the new missile adds a greater number of more capable attitude control motors (ACMs), compared to the PAC-3 MSE. These small thrusters ring the missile’s forward body.

PAC-3 Missile: How The System Works

The new characteristics could be particularly important against maneuvering ballistic missile warheads and hypersonic weapons, which can pose difficult interception problems because of their speed, altitude and dynamic flight profiles. However, the company has yet to demonstrate PAC-3 Edge’s performance in flight testing.

The extent to which PAC-3 Edge could overlap with, or potentially augment, the capabilities of the Army’s Terminal High Altitude Area Defense (THAAD) system also remains unclear. THAAD is designed to intercept ballistic missiles at higher altitudes and longer ranges than Patriot, where midcourse window bleeds into the terminal intercept window. If PAC-3 Edge delivers a substantial improvement in engagement range and altitude over PAC-3 MSE, it could potentially provide at least some backfill for THAAD.

The announcement did not provide detailed performance figures for the new interceptor, including its maximum engagement range, speed, or specific target set. It also did not establish how much better the missile will perform than the PAC-3 MSE in operational conditions.

Addressing An Air Defense Force Under Pressure

The Army has a pressing need to improve its air and missile defense capabilities while expanding the number of interceptors available to its forces.

TWZ has been reporting on the strain facing the Patriot force and its interceptor supply for years. In July 2025, we reported on the Army’s plan to expand its Patriot air defense force by roughly a quarter, adding four battalions as the service sought to meet growing operational demands. More recently, we have detailed the challenges of replenishing interceptors after intensive combat operations, including the scale of U.S. missile and drone engagements in the Middle East, as well as transfers to Ukraine.

Related to this, the push for a more capable Patriot interceptor comes as the system faces increasingly sophisticated threats and adversaries that have learned from years of combat. Russia has improved its ballistic missile tactics to pierce the Patriot’s protective umbrella, while Iran has demonstrated ways to exploit gaps in layered missile defenses, including introducing extremely high-speed ballistic missiles and cluster warheads that open at high altitude.

PAC-3 MSE is currently the most advanced operational member of the PAC-3 family. It is designed primarily as a hit-to-kill interceptor, destroying targets through the force of direct impact, but it also incorporates a small explosive charge known as a “lethality enhancer,” as TWZ has previously detailed.

PAC-3 Edge is intended to push those capabilities further still. Lockheed says the new missile is being designed to work within the Army’s existing and future integrated air and missile defense architecture, including the Integrated Battle Command System (IBCS) and the M903 Patriot launcher. The company has also identified containerized launchers and HIMARS Flex among the systems with which it intends to integrate the interceptor.

Such compatibility could allow the service to retain much of its existing infrastructure while improving the performance of the weapons used within it.

The precise extent of that compatibility, however, will depend on development, testing, and integration work that remains ahead.

Production And Cost

Lockheed is developing PAC-3 Edge as the company and the Pentagon work to expand production of the existing PAC-3 MSE.

In January, Lockheed Martin announced a seven-year agreement with the Pentagon to more than triple annual PAC-3 MSE production capacity, initially targeting an increase from roughly 600 interceptors to 2,000 a year. The effort subsequently received a major funding boost in July, when the U.S. government awarded Lockheed a contract modification worth up to $53.86 billion, bringing the total multiyear contract value to $58.62 billion. Lockheed says the effort is intended to more than triple production by the end of 2030, while expanding its workforce and investing in manufacturing infrastructure and its supply chain.

Those efforts could provide a foundation for producing PAC-3 Edge if the missile completes development and enters service. Lockheed has said the new interceptor will be manufactured on its existing PAC-3 production line in Camden, Arkansas, with factory modernization expected to support the eventual transition.

The company has also highlighted substantial internal investment in the new missile and its seeker technology. That investment could reduce development risk and give Lockheed greater control over critical components, although the program’s final cost and production schedule remain important unknowns.

The broader challenge is not simply developing an interceptor with better performance. Advanced missiles can be expensive, and air defense forces must balance the capabilities of individual weapons against the number they can afford to procure and keep available. Sustained combat operations can rapidly consume interceptor inventories, making production rates and replacement costs central considerations.

Cahill says the company has also identified the opportunity to mix and match components between PAC-3 Edge and other missile offerings from Lockheed Martin. “We are getting increasingly modular, and increasingly we’re mixing and matching pieces and parts,” he said.

Ultimately, if it chooses PAC-3 Edge, the U.S. government will decide exactly how to handle production of the PAC-3 MSE and the new missiles. “We would expect the typical thing is you’ll feather them, so you would expect that over time MSEs would come down,” Cahill continued. “We’re still talking, seven, eight, nine, 10 years away. You would expect that the Edge production would go up, but there’s plenty of capacity in the factory to manage whatever surges are going to be needed there.”

At the same time, it should be noted that Lockheed Martin is also working on a lower-cost PAC-3 development, the PAC-3 Adapted Capability Effector (ACE). The company says that this interceptor will cost less than half as much as the PAC-3 MSE, meaning it would have a price tag of around $2.5 million. The company says that the PAC-3 ACE will preserve two-thirds of the capability the PAC-3 MSE had, and it has already generated considerable international interest.

Future Interceptor Competition

Lockheed has confirmed that it is one of two companies selected to continue in the Army’s Future Interceptor competition. The identity of the other competitor has not yet been disclosed, and the Army has not publicly provided a complete account of the competition’s requirements.

The effort follows the cancellation of the earlier Lower-Tier Future Interceptor (LTFI) program, which had involved Lockheed Martin and Raytheon. At the time, the Army opted to focus on upgrades to the PAC-3 MSE and on better integration of its existing air and missile defense systems.

The renewed competition suggests that incremental upgrades alone may not be sufficient to address the Army’s longer-term requirements. The development of faster, more maneuverable missiles and other advanced aerial threats is driving demand for interceptors capable of operating across a wider engagement envelope.

For PAC-3 Edge, which is designed to address emerging threat requirements, the planned 2027 testing start and 2031 deployment target leave substantial development work to complete, including demonstrating the seeker’s performance, validating the propulsion system, and proving the missile’s ability to engage representative targets.

For now, the unveiling establishes the direction Lockheed wants to take the Patriot interceptor family. Whether PAC-3 Edge can deliver the promised increase in performance, while meeting the Army’s cost and production requirements, will become clearer as the program progresses. Regardless, from what is being experienced on the battlefield, a more capable, higher-reaching Patriot would be a very welcome addition to the Army’s Patriot family.
