Advanced Technology Support Program IV (ATSP4)

The Defense Microelectronics Activity established Advanced Technology Support Program IV (ATSP4), a Master IDIQ for development and insertion of advanced microelectronic solutions across DoD weapon systems, with a last date to order of March 31, 2026, now closed. The vehicle carried a combined potential value of $17.5 billion across 677 task orders, of which $9.4 billion (93 percent) was obligated before ordering ceased. Predecessor vehicle ATSP III (awarded 2003) was succeeded by DMEA Advanced Technology Support Program 5 (awarded April 1, 2026).

Scope spans hardware and software development, studies, analysis, design, simulation, prototyping, integration, testing, producibility, and limited production to address obsolescence, supply assurance, trusted microelectronics, and performance enhancement across fighter aircraft (F-16, F-35, F/A-18), strategic bombers (B-2, B-52H), missiles (Small Diameter Bomb, Stormbreaker, Excalibur), rotorcraft (MH-60, P-8A Poseidon), radar systems (ROTHR, Umbriel), anti-submarine platforms, counter-unmanned aircraft systems, and test-range infrastructure. Recent task orders show work on air-base air defense systems for AFRICOM, weather modeling systems, submarine trainer modernization, and cyber security software.

Raytheon Company dominated the vehicle with 288 orders worth $5.39 billion in combined potential value, followed by Northrop Grumman Systems Corporation at 213 orders and $3.05 billion. Lockheed Martin, BAE Systems Information and Electronic Systems Integration, and General Dynamics Mission Systems held smaller shares. These five firms captured 93 percent of task orders and 98 percent of potential value; no other primes are named.

Ordering activity remained steady through the vehicle's final year: 2022 through 2025 averaged 56 orders annually; 2026 saw only nine orders before the March 31 cutoff. The Army Acquisition Support Center's PEO Missiles and Space placed the most orders (98 task orders, $3.73 billion combined potential value), followed by DMEA itself (111 orders, $1.63 billion), Office of the Secretary of Defense (46 orders, $811.6 million), Naval Air Systems Command (52 orders, $396.6 million), and Naval Sea Systems Command (42 orders, $302.2 million). These top five customers account for 52 percent of all task orders.

All 677 task orders were awarded without set-aside restrictions. Cost-Plus-Fixed-Fee was the dominant pricing type; a minority of recent orders used Firm Fixed Price or Cost No Fee. Task-order ceilings in the visible portfolio ranged from under $1 million to $262.9 million. Large recent orders included a $262.9 million sense-and-intercept equipment order (obligated September 2025), a $216.9 million counter-unmanned aircraft system order (August 2024), a $146.8 million Excalibur obsolescence solution (September 2024), and a $133.8 million air-base air defense order (April 2026, $103.6 million obligated). Most orders carried 12- to 36-month performance periods extending into 2026, 2027, or 2028.

Advanced Technology Support Program IV (ATSP4) is a uniform technical and management approach that leverages advanced technologies to meet the requirements of the Department of Defense (DoD) for a quick reaction capability across the entire spectrum of technology development, acquisition, and long-term support. This capability includes the development of appropriate solutions to keep a system operational, elevate sophistication level, or meet new threats. These efforts may include developing components to meet the DoD's requirements for ultra-low volumes, extending component availability, or ensuring a trusted, assured, and secure supply of microelectronics; also included will be the intelligent and rapid application of advanced technologies to add needed performance enhancements to DoD weapon systems in response to traditional and irregular (asymmetric) threats and to the problems related to aging weapon systems. Increasing warfighter capabilities and providing solutions to electronics support problems-such as, reliability, maintainability and obsolescence-are accomplished through the development and insertion of applications of advanced microelectronics technologies. The scope of ATSP4 covers both hardware and software and includes studies, analysis, design, software, simulation, prototyping, integration, testing, producibility, and limited production. The scope of ATSP4 also includes the development of viable methods and procedures for using available tools and resources, strategies for resolution of replacement alternatives, and technical interchange in support of task accomplishment.
