WASHINGTON — May 16, 2026 : The U.S. Army has awarded Lockheed Martin a $61 million cost-plus-incentive-fee contract to develop and demonstrate two major upgrades for the Patriot air and missile defense system, aimed at improving the system’s survivability, flexibility, and ability to counter modern multi-directional aerial threats.
The contract, issued by the Army Contracting Command at Redstone Arsenal, Alabama, was awarded to Lockheed Martin Missile and Fire Control in Grand Prairie, Texas. The work includes development of the Missile Segment Enhancement (MSE) Containerized Launcher and the Remote Interceptor Guidance 360 Degrees (RIG-360) Containerized System. The agreement also covers hardware-in-the-loop testing activities, support for flight test execution, and production of three RIG-360 Integrated Assemblies.
According to contract details, work locations and funding allocations will be determined on an order-by-order basis, with overall completion scheduled for May 31, 2027.
The modernization effort forms part of the U.S. Army’s broader Integrated Air and Missile Defense strategy, which seeks to improve the ability of Patriot batteries to operate in highly contested environments against ballistic missiles, cruise missiles, drones, and coordinated saturation attacks.
Patriot System Remains Backbone of U.S. Air Defense
The Patriot system remains the U.S. military’s primary long-range surface-to-air missile defense platform and is currently operated by more than a dozen allied countries worldwide. Developed jointly by Lockheed Martin and RTX Corporation, the system has been continuously upgraded since entering service in the 1980s.
Patriot batteries have seen operational deployment during the Gulf War, Operation Iraqi Freedom, and ongoing operations in Ukraine. The system is designed to intercept aircraft, cruise missiles, tactical ballistic missiles, and other aerial threats.
Central to the Patriot system is the PAC-3 interceptor missile, manufactured by Lockheed Martin. Unlike conventional surface-to-air missiles that rely on blast fragmentation warheads, the PAC-3 employs hit-to-kill technology, destroying incoming targets through direct kinetic impact. This approach significantly increases interception precision against high-speed ballistic threats.
The latest PAC-3 Missile Segment Enhancement interceptor variant offers improved range, maneuverability, and altitude performance compared to earlier Patriot interceptors and has become a core element of U.S. and allied missile defense architecture.
Addressing Patriot’s Longstanding Sensor Coverage Limitation
One of the primary objectives of the new contract is to resolve a longstanding operational limitation associated with conventional Patriot batteries.
Current Patriot configurations rely primarily on the AN/MPQ-65 radar, a sectored fire-control radar that scans a fixed azimuth sector rather than providing complete hemispherical coverage around a defended position. While highly capable within its assigned sector, the radar does not provide native 360-degree surveillance and engagement capability.
Because PAC-3 interceptors require continuous fire-control-quality tracking and uplink guidance during flight, Patriot batteries are most effective against threats approaching within the radar’s designated coverage arc. This has historically forced commanders to orient Patriot batteries toward the most likely direction of attack, creating operational rigidity in environments where threats can emerge from multiple axes simultaneously.
Modern missile warfare increasingly involves coordinated attacks using ballistic missiles, cruise missiles, drones, and decoys launched from varying directions and altitudes. Such tactics can exploit gaps in sectored air defense systems by forcing defenders to divide coverage priorities or reposition sensors and launchers during combat operations.
The Army’s new RIG-360 effort is intended to eliminate that limitation.
RIG-360 Designed for Full 360-Degree Engagement Capability
The Remote Interceptor Guidance 360 Degrees system, known as RIG-360, is a software-defined hemispherical missile communications system designed to provide uninterrupted PAC-3 missile uplink capability regardless of radar orientation.
Instead of relying on a dedicated missile uplink antenna physically tied to a single Patriot radar, the RIG-360 operates through the Army’s Integrated Battle Command System (IBCS), developed by Northrop Grumman.
IBCS serves as the Army’s next-generation integrated fire-control network and command-and-control architecture. The system links radars, launchers, command nodes, and interceptor systems from multiple air defense platforms into a unified network, enabling sensors and weapons from different systems to share targeting data in real time.
Through integration with IBCS, the RIG-360 can receive fire-control-quality tracking data from any compatible sensor connected to the network rather than depending exclusively on the Patriot radar itself. The system then converts that targeting information into missile guidance communications for PAC-3 interceptors already in flight.
This architecture allows Patriot missiles to engage threats approaching from any direction without requiring repositioning of the battery’s primary radar or launcher orientation. In practical terms, the system transforms Patriot from a largely sectored engagement platform into a network-enabled, all-direction engagement capability.
The Army views the concept as essential for future battlefield environments where dispersed forces may face simultaneous attacks from multiple directions using mixed missile and drone salvos.
Prior Testing and Development History
The current contract builds upon earlier development milestones associated with the RIG-360 program.
Lockheed Martin previously conducted a successful flight test of the prototype system at White Sands Missile Range in New Mexico in 2022. During the test, a PAC-3 interceptor successfully engaged a cruise missile target using guidance data transmitted through the prototype 360-degree architecture.
The company also completed the first phase of the Engineering, Manufacturing and Development effort under a prior contract awarded in May 2025 reportedly valued at approximately $114 million.
The latest $61 million award advances the program into additional demonstration and integration activities intended to support future operational deployment.
Containerized Launcher Intended to Improve Mobility and Survivability
In addition to the RIG-360, the contract funds development of the Missile Segment Enhancement Containerized Launcher, a redesigned Patriot launcher configuration intended to reduce logistical complexity and improve deployment flexibility.
The standard Patriot M901 launcher is a large, highly specialized platform that requires dedicated transport equipment and significant support infrastructure for emplacement and sustainment. While effective in fixed or semi-fixed defensive roles, the traditional launcher design can limit rapid dispersal and mobility.
The new containerized launcher concept places PAC-3 MSE missile launch capability onto a standard intermodal shipping container chassis. By using commercially compatible containerized transport formats, the Army aims to simplify transportation, increase deployment options, and reduce the logistical footprint associated with Patriot operations.
The containerized design may also support more distributed defensive layouts, enabling missile launchers to be positioned farther apart rather than concentrated around a single radar unit. Military planners increasingly view such dispersion as necessary to improve survivability against precision-guided strikes targeting fixed air defense sites.
The launcher modernization effort aligns with the Army’s broader transition toward distributed and mobile air defense architectures capable of operating in contested environments where static infrastructure is vulnerable to long-range missile attacks.
Integration With Broader Army Air Defense Modernization
The Patriot modernization program is closely tied to several parallel Army air and missile defense initiatives.
One of the most significant is the Lower Tier Air and Missile Defense Sensor (LTAMDS), a next-generation radar developed to replace the AN/MPQ-65. Unlike earlier Patriot radars, LTAMDS is designed to provide native 360-degree radar coverage using active electronically scanned array technology.
When combined with IBCS and RIG-360, LTAMDS is expected to create a fully integrated air defense architecture in which sensors, launchers, and interceptors operate as distributed networked nodes rather than isolated battery components.
The Army’s long-term objective is to create a system where any available sensor can provide targeting data to any compatible interceptor within the network, improving engagement flexibility while reducing vulnerabilities associated with centralized radar dependence.
IBCS itself has become a central element of that strategy by resolving historical interoperability limitations between different missile defense systems. The architecture enables systems such as Patriot, Sentinel radars, LTAMDS, and other air defense assets to share data across a common operational picture.
Army officials have repeatedly identified integrated fire control and sensor networking as critical requirements for countering increasingly sophisticated missile threats developed by near-peer adversaries.
Operational Lessons From Ukraine
Recent combat experience in Ukraine has significantly influenced U.S. Army air defense modernization priorities.
Ukrainian Patriot batteries have faced sustained attacks involving Russian ballistic missiles, cruise missiles, drones, and mixed salvos launched from multiple directions simultaneously. These attacks frequently combine varying altitudes, flight profiles, and approach vectors intended to stress air defense networks and expose coverage limitations.
Such operational conditions have reinforced the importance of 360-degree engagement capability and distributed launcher configurations capable of surviving repeated precision strikes.
Military analysts have noted that modern missile warfare increasingly favors dispersed defensive systems connected through resilient command-and-control networks rather than centralized batteries with fixed sensor orientation.
The RIG-360 and containerized launcher efforts directly address those battlefield observations by improving Patriot’s ability to engage threats approaching from unexpected directions while enabling more flexible deployment concepts.
The Army’s investment in the two programs reflects a broader effort to adapt existing air defense systems for future high-intensity conflicts involving large-scale missile and drone attacks against both military forces and critical infrastructure.
With work continuing through 2027, the upgrades are expected to play a key role in shaping the next phase of Patriot modernization and the future architecture of U.S. integrated air and missile defense networks.
