PAC-3 MSE Achieves 360 Degree Engagement with LTAMDS Radar Integration
Lockheed Martin’s PAC-3 MSE integrates with Raytheon’s LTAMDS radar to enable 360-degree air defense, enhancing U.S. Army capabilities and allied deployments.
The successful demonstration of 360-degree engagement capability by Lockheed Martin’s PAC-3 Missile Segment Enhancement (MSE) system marks a pivotal advancement in air defense technology. This achievement, validated through a flight test using the Lower Tier Air and Missile Defense Sensor (LTAMDS), represents the convergence of decades of missile defense evolution with state-of-the-art radar technology. The result is an unprecedented defensive capability for the U.S. Army’s Integrated Air and Missile Defense (IAMD) architecture. The integration of PAC-3 MSE and LTAMDS is not just a technical feat but also a strategic one, as modern battlefields demand the ability to counter threats from any direction, moving beyond the traditional forward-facing defense postures.
This milestone is significant for military planners who recognize that future conflicts will likely involve sophisticated, multidirectional attacks. The ability to track and engage multiple threats from any azimuth is a fundamental shift in defensive doctrine, and the PAC-3 MSE/LTAMDS combination is at the forefront of this transformation. The following sections break down the technical, operational, and strategic implications of this advancement, drawing on recent developments, expert perspectives, and real-world performance data.
The PAC-3 MSE’s roots trace back to the original MIM-104 Patriot system, developed during the Cold War to counter aircraft and early ballistic missile threats. The system’s initial combat deployment during the 1991 Gulf War revealed limitations that spurred a series of upgrades, resulting in the PAC-2 GEM and subsequently the PAC-3 family. Each iteration incorporated lessons learned from operational experience, with the PAC-3 MSE representing the most advanced variant to date.
Lockheed Martin’s PAC-3 MSE upgrade introduced a more powerful dual-pulse solid rocket motor, extending the missile’s range by up to 50% over previous versions. The missile employs hit-to-kill technology, which destroys incoming threats through direct impact, increasing lethality while minimizing collateral damage. This capability is especially valuable in urban or densely populated areas where traditional fragmentation warheads pose greater risk.
Technical enhancements also include enlarged, folding control surfaces for improved maneuverability and compatibility with existing launchers. The missile’s active Ka-band Radar-Systems seeker allows for high-resolution target tracking and autonomous guidance, with recent software upgrades further improving performance in complex, cluttered environments.
“PAC-3 continues to demonstrate advanced, reliable performance in increasingly complex operational environments. Delivering 360-degree engagement capability will enable soldiers to defend against threats from any direction, enhancing the U.S. Army’s IAMD capabilities.” — Brian Kubik, Vice President, PAC-3 Programs, Lockheed Martin
The Lower Tier Air and Missile Defense Sensor (LTAMDS), developed by Raytheon, is designed to address advanced threats, including hypersonic weapons. Unlike legacy Patriot radars, LTAMDS features a three-array configuration, one primary array and two secondary arrays, to provide uninterrupted 360-degree coverage. This design eliminates the blind spots inherent in earlier systems and allows for simultaneous detection and engagement of threats from any direction.
LTAMDS leverages Gallium Nitride (GaN) technology, which offers greater power efficiency and reliability compared to previous gallium arsenide-based systems. The radar’s increased power output and advanced signal processing capabilities enable it to track multiple targets at longer ranges and with higher accuracy. The system’s accelerated development timeline, from contract award in 2019 to production approval in 2025, reflects its strategic importance and the urgency of modernizing U.S. air defenses.
Integration with the Army’s Integrated Battle Command System (IBCS) and compatibility with both PAC-2 and PAC-3 interceptors were key challenges overcome through extensive joint testing and software development. The success of the 2025 flight test, in which a PAC-3 MSE intercepted a target using data from LTAMDS’s secondary sector, validated the radar’s distributed engagement capability. The 360-degree engagement capability fundamentally changes how air and missile defense is approached on the battlefield. Traditional systems required careful placement to cover anticipated threat vectors, often leaving gaps that adversaries could exploit. The PAC-3 MSE/LTAMDS combination eliminates these vulnerabilities, enabling defense against multi-vector attacks, including coordinated strikes involving ballistic missiles, cruise missiles, Drones, and aircraft.
This technological leap allows commanders to optimize defensive asset allocation and respond to threats more flexibly. The system’s networked architecture, enabled by IBCS, means that sensors and interceptors no longer need to be co-located, allowing for distributed operations and improved survivability. The Army’s plan to add four new Patriot battalions, with LTAMDS-equipped units providing the capability of up to 30 battalions through distributed deployment, exemplifies this shift.
Strategic deployments, such as the fielding of LTAMDS on Guam, demonstrate the system’s value in protecting critical infrastructure in regions exposed to multidirectional threats. The Guam deployment also serves as a real-world testbed for further capability refinement, with lessons learned informing broader operational concepts.
Growing demand for PAC-3 MSE interceptors, both domestically and internationally, has driven Lockheed Martin and its partners to expand production capacity. The Camden, Arkansas facility’s expansion and Boeing’s increased seeker output are examples of investments made to meet rising orders, with production targets exceeding 600 missiles annually by 2025. Lead times for new interceptors remain lengthy, typically 34 to 36 months, reflecting the complexity of the supply chain and the need for rigorous quality control.
Unit costs for PAC-3 MSE interceptors range from $3.7 million to $7 million, depending on configuration and support packages. Full Patriot batteries can cost from $360 million to over $1 billion when fully equipped. These figures are comparable to other advanced missile systems, such as the Navy’s SM-6. The economic impact of the program is substantial, supporting jobs across multiple states and strengthening the U.S. defense industrial base.
Internationally, the PAC-3 MSE has been adopted by seventeen countries, with major recent sales to Germany, Romania, and Kuwait. Germany’s $5 billion purchase of up to 600 Patriot missiles underscores the system’s appeal to NATO allies seeking to modernize their air defenses. The system’s combat record, including use by Ukraine against Russian ballistic and hypersonic missiles, further bolsters its reputation and marketability.
“The enhanced capability provided by PAC-3 MSE and LTAMDS integration effectively doubles defensive capacity without requiring proportional increases in personnel or equipment.” — U.S. Army leadership statement
Recent flight tests have validated significant upgrades to the PAC-3 MSE’s seeker algorithms, improving the missile’s ability to distinguish between actual threats and countermeasures such as decoys and electronic interference. The dual-pulse rocket motor provides greater thrust and extended range, while enlarged control surfaces enable high agility during terminal engagement. These features are critical for intercepting maneuvering targets, including hypersonic glide vehicles and advanced ballistic missiles.
The missile’s active Ka-band radar seeker, combined with ground-based command updates, allows for rapid in-flight course corrections. This capability is essential for engaging fast-moving and unpredictable threats, as demonstrated in recent combat operations. The missile is also designed for compatibility with existing launchers and support infrastructure, minimizing the need for costly system overhauls. Reliability and maintainability have been priorities in the system’s design, with improvements in thermal hardening, insensitive munitions, and electronic components. These features ensure consistent performance in diverse operational environments, from the Middle East to Eastern Europe.
The deployment of Patriot systems to Ukraine has provided valuable real-world data on the PAC-3 MSE’s effectiveness against advanced threats. Ukrainian forces have used the system to intercept hypersonic Kinzhal missiles and other Russian ballistic threats, achieving the first confirmed hypersonic intercepts in combat history. However, operational reports indicate that interception rates against maneuvering ballistic missiles remain a challenge, with salvo firing often required to ensure target destruction.
These operational lessons have informed ongoing software and hardware upgrades, particularly in seeker algorithms and networked sensor fusion. The experience in Ukraine also highlights the dynamic nature of modern missile threats and the need for continuous adaptation of defensive systems.
Middle East deployments have further validated the system’s reliability, with extended operational periods and successful intercepts of Iranian missiles. These deployments demonstrate the PAC-3 MSE’s ability to operate effectively under sustained, high-tempo conditions.
“The operational experience in Ukraine has generated critical insights into both system capabilities and limitations. PAC-3 MSE interceptors successfully engaged Kinzhal hypersonic missiles, achieving the first confirmed hypersonic intercepts in combat history.” — Defense News analysis
The demonstration of 360-degree engagement capability by the PAC-3 MSE, enabled by LTAMDS, is a transformative step in air and missile defense. It addresses the evolving threat environment where attacks can come from any direction and adversaries employ increasingly sophisticated tactics. The integration of advanced interceptors with next-generation radar and command networks creates a flexible, resilient defense architecture that can adapt to new challenges.
Looking ahead, continued investment in artificial intelligence, sensor fusion, and network-centric operations will further enhance the system’s capabilities. As more allied nations adopt the PAC-3 MSE and LTAMDS, interoperability and collective defense will become even more robust. The U.S. and its partners are poised to maintain a technological edge in air defense, ensuring protection for critical assets and populations in an era of rapidly evolving threats.

Northrop Grumman and Kratos Win USMC MUX TACAIR Contract
Northrop Grumman and Kratos to develop USMC’s MUX TACAIR uncrewed aircraft system with Prism software and Valkyrie airframe integration.
This article is based on an official press release from Northrop Grumman.
Northrop Grumman has been competitively awarded a contracts by the U.S. Marine Corps to develop the Marine Air-Ground Task Force Uncrewed Expeditionary Tactical Aircraft (MUX TACAIR). The project, formally classified as a Collaborative Combat Aircraft (CCA) initiative, aims to field a sophisticated “loyal wingman” system capable of operating in high-threat environments alongside manned fighters.
Announced on January 8, 2026, the agreement positions Northrop Grumman as the prime contractor with Kratos Defense & Security Solutions serving as the key subcontractor. The team will integrate Northrop’s advanced mission systems into the flight-proven Kratos XQ-58A Valkyrie airframe. This “best of breed” strategy is designed to accelerate the deployment of automation systems for the Marine Corps.
According to the announcement, the initial period of performance is set for 24 months with a contract value of approximately $231.5 million. The program’s primary objective is to rapidly develop, integrate, and field an uncrewed aircraft system (UAV) that meets the Marine Corps’ unique requirements for expeditionary operations.
The partnerships leverages the specific strengths of both defense firms. Northrop Grumman will act as the Lead Systems Integrator, providing the “Advanced Mission Kit.” This package includes sensors, communications, and software-defined technologies driven by “Prism,” Northrop’s proprietary autonomy software.
Kratos Defense will supply the XQ-58A Valkyrie, a stealthy, high-performance uncrewed aerial system that has already demonstrated its capabilities in flight. By utilizing an existing airframe, the team aims to bypass the long lead times associated with clean-sheet aircraft designs.
Northrop Grumman’s “Prism” software is central to the program’s adaptability. Described as an open-architecture system, Prism allows for the rapid integration of third-party modules or “apps.” This plug-and-play capability ensures that the Marine Corps can swap mission profiles, switching from electronic warfare to surveillance, for example, without needing to rewrite core flight code.
In a statement regarding the award, Krys Moen, Vice President at Northrop Grumman, emphasized the speed and reduced risk of this approach: “This partnership offers a low risk, expedited path to mission capability. Combining a proven airframe with our proven mission systems avoids the delays inherent in a clean-sheet design.”
The MUX TACAIR program is closely aligned with the U.S. Marine Corps’ Force Design 2030 strategy, which prioritizes dispersed operations and “Stand-in Forces” in the Indo-Pacific region. A critical requirement for this program is runway independence.
The XQ-58A Valkyrie is designed to be launched via rocket assist from a rail system, which can be mounted on trucks or ships, and recovered via parachute. This capability eliminates reliance on traditional airfields, which are viewed as vulnerable static targets in modern conflict scenarios. The aircraft boasts high-subsonic speeds of approximately Mach 0.85 and a range exceeding 3,000 nautical miles, allowing it to serve as a forward sensor node or “quarterback” that relays targeting data to F-35s and ground units.
Steve Fendley, President of Kratos Unmanned Systems, highlighted the economic and operational advantages of the platform:
“The integration results in a high-capability CCA at a price point that enables the uncrewed systems to be deployed in mass.”
The immediate 24-month contract period will focus on integrating the Northrop mission kit into the Valkyrie airframe and conducting a series of flight tests. The program is structured around a “spiral” development model, where capabilities are added incrementally. Initial operational focuses are expected to include surveillance and electronic warfare, with lethal strike capabilities planned as the autonomy software matures.
The ultimate operational goal is to field a capability that can be deployed with Marine Expeditionary Units (MEUs) before the end of the decade, providing organic air support that does not require large aircraft carriers.
The selection of the Kratos Valkyrie for the MUX TACAIR program underscores a significant divergence between Air Force and Marine Corps acquisition strategies for Collaborative Combat Aircraft (CCA). While the U.S. Air Force has largely focused on runway-dependent systems for its CCA increments, the Marine Corps has remained steadfast in its requirement for runway independence.
By choosing a rail-launched, parachute-recoverable system, the USMC is effectively future-proofing its air support against runway denial tactics. Furthermore, the “attritable” nature of the Valkyrie, meaning it is low-cost enough to be lost in combat without catastrophic financial or strategic impact, aligns perfectly with the need for mass in contested environments. This contract validates the industry’s shift toward separating the airframe commodity from the high-value software and sensor packages, a trend that is likely to define the next generation of uncrewed military-aircraft aviation.

Lockheed Martin Demonstrates Cross-Border UAS Autonomy Integration
Lockheed Martin showcased MDCX and Vigilance integration enabling secure, multi-domain control of multiple uncrewed aerial systems in the UK.
This article is based on an official press release from Lockheed Martin.
On January 8, 2026, Lockheed Martin successfully completed a live demonstration of its advanced command and control (C2) capabilities at the Predannack National Drone Hub in Cornwall, United Kingdom. The event highlighted the integration of U.S. and U.K. defense technologies, specifically pairing the U.S.-developed Multi-Domain Combat System (MDCX™) with the U.K.-developed Vigilance mission system.
According to the company’s announcement, the demonstration proved that a single operator could simultaneously manage multiple classes of uncrewed aerial systems (UAS) within a secure, multi-domain environment. This achievement marks a significant step in coalition interoperability, offering a “suite of capability” designed to be exportable to international allies while maintaining high security standards.
The demonstration featured a scenario where the MDCX™ autonomy platform commanded two distinct types of drones: the Indago 2 quadcopter (Group 1) and the Stalker fixed-wing UAS (Group 2). While MDCX managed the flight autonomy and mission planning, the Vigilance system handled sensor data fusion.
Lockheed Martin described the technical breakdown of the systems involved:
In a specific test of mission capability, the Indago 2 drone utilized a Software Defined Radio Payload to re-broadcast sonobuoy data, simulating an anti-submarine warfare mission managed by the integrated systems.
Lockheed Martin successfully completed a live demo of its ‘suite of capability’ for uncrewed system command and control featuring the MDCX™ and Vigilance.
— Lockheed Martin Press Release
This demonstration addresses a longstanding friction point in international defense acquisitions: the balance between purchasing advanced U.S. platforms and maintaining sovereign control over mission data. By integrating the U.K.-sovereign Vigilance Software with the U.S. MDCX architecture, Lockheed Martin is validating a modular approach to defense sales.
We observe that this “Open Architecture” model aligns with the U.S. Department of Defense’s vision for Joint All-Domain Command and Control (JADC2). Rather than relying on proprietary, closed-loop systems, the industry is shifting toward modularity that allows allies to plug domestic sensor algorithms into U.S. operating systems. Furthermore, the specific platforms used in this demonstration, Stalker and Indago, are directly relevant to the British Army’s “TIQUILA” program. Awarded to Lockheed Martin UK in late 2022, the £129 million TIQUILA contract focuses on providing uncrewed intelligence, surveillance, and reconnaissance (ISR) capabilities. This successful integration suggests a pathway for enhancing those existing assets with advanced autonomy and cross-domain connectivity.

Marshall Recognized as Global Leader in C-130 Hercules MRO
Marshall is the only global Center of Excellence for C-130 Hercules structural modifications, expanding operations with new contracts and facilities.
This article is based on official press releases and public reporting from Marshall and Lockheed Martin.
As of January 2026, Marshall (formerly Marshall Aerospace) has solidified its position as the world’s leading independent authority on the Lockheed Martin C-130 Hercules. With a partnership spanning more than half a century and a recent designation as the only global Center of Excellence for critical structural modifications, the company has become a linchpin in the logistics network of 17 government fleet operators worldwide.
Recent developments from 2024 through late 2025 have seen the company expand its footprint significantly, particularly in North America and the Middle East. By securing major contracts with the Turkish Ministry of National Defence and operationalizing a new facility in Greensboro, North Carolina, Marshall has demonstrated its capacity to support both legacy and Super Hercules fleets with unrivaled technical expertise.
Marshall’s relationship with the C-130 platform dates back to 1966, shortly after the Royal Air Force (RAF) took delivery of its first aircraft. Over the decades, the company has accrued a unique set of accreditations from the Original Equipment Manufacturer (OEM), Lockheed Martin.
According to company data, Marshall holds the distinction of being the first authorized Hercules Service Center (HSC) for legacy models and the first Heavy Maintenance Center (HMC) for the modern C-130J Super Hercules. In a landmark achievement in November 2024, Lockheed Martin officially recognized Marshall as the world’s first authorized Center of Excellence for Center Wing Box (CWB) replacements.
“Recognising Marshall as the first Lockheed Martin-approved Centre of Excellence for its work leading the C-130 centre wing box replacement programme is a natural choice… Marshall is a vital part of the C-130 Hercules community.”
, Rod McLean, VP at Lockheed Martin (2024)
Marshall’s capabilities extend well beyond standard maintenance, encompassing complex structural modifications often described as “aerospace surgery.” The most notable of these is the Center Wing Box (CWB) replacement, a procedure likened to spinal surgery for the aircraft.
The CWB is the primary structure connecting the wings to the fuselage. Replacing it is one of the most complex engineering tasks associated with the C-130. Marshall is currently the only organization globally, outside of Lockheed Martin’s own U.S. facilities, authorized to perform these replacements on the C-130J. Data indicates that as of late 2025, Marshall had completed nearly 80 CWB replacements across both legacy and J-model aircraft. This capability was highlighted when “Fat Albert,” the U.S. Navy Blue Angels’ iconic C-130J, returned to Marshall in late 2025 for this specific structural life-extension procedure.
In addition to structural work, Marshall has advanced its avionics modernization programs. Recent projects include bespoke navigation upgrades for the Austrian Air Force, completed in late 2024, and similar integrations for the French Air Force. These upgrades typically involve replacing analog systems with modern Flight Management Systems (FMS) and GPS landing capabilities.
Furthermore, the company holds a unique “authority to manufacture” from Lockheed Martin. To mitigate global supply chain delays, Marshall manufactured over 2,000 parts in 2024 alone, ensuring that maintenance schedules remained on track.
The last two years have marked a period of aggressive geographic expansion and contract acquisition for Marshall.
In 2025, the company fully operationalized its new maintenance facility in Greensboro, North Carolina. This site was established primarily to service the U.S. Marine Corps (USMC) fleet of KC-130J tankers under a 10-year contract originally awarded in 2020. As of July 2025, reports show that Marshall had worked on 42 different USMC aircraft and manufactured over 1,500 parts specifically for that fleet.
Marshall has also strengthened its presence in Europe and Asia:
The consolidation of C-130 MRO capabilities under Marshall highlights a critical trend in defense logistics: the reliance on specialized independent contractors to extend the life of aging airframes. With the C-130 remaining the “world’s workhorse,” the ability to perform heavy structural modifications like CWB replacements outside of the OEM’s primary facilities is essential for maintaining global fleet readiness. Marshall’s “authority to manufacture” also suggests that decentralized supply chains are becoming a priority for defense contractors seeking to insulate themselves from global logistics disruptions.
Marshall’s operational volume reflects its central role in the global defense sector. In 2024, the company completed nearly 30,000 MRO tasks, totaling over 442,000 hours of aircraft work. Through its various life-extension programs, Marshall estimates it has added over 1,600 collective years to the lifespan of the global C-130 fleet.
“Our unique approvals allow us to de-risk maintenance and ensure predictable turnaround times for military operators.”
, Gareth Williams, COO at Marshall
