Army Evaluation Center Support Services (AECSS)

The Army Test and Evaluation Command established this Master IDIQ on May 28, 2020, for engineering and test support services across all Army Evaluation Center (AEC) directorates and divisions; the ordering period closed on May 27, 2025, and the vehicle is no longer accepting new orders. The vehicle succeeded an earlier Army Evaluation Center Services IDIQ awarded in 2014.

The ordering period generated 19 task orders with a combined potential value of $283.7 million and $155.3 million in obligated dollars (55% of potential). Recent momentum has been robust: seven orders were issued in 2025 alone (through August), compared to three in 2021 and one in 2023, signaling renewed customer demand before the ordering window closed. Work is performed primarily at Aberdeen Proving Ground, Maryland, with temporary duty at other locations as needed. All task orders are priced Cost Plus Fixed Fee.

Man-Machine Systems Assessment (MSA), Incorporated dominates the vehicle, holding six orders worth $171.7 million in combined potential value—roughly 61% of the total. Joint Research and Development LLC ranks second with five orders totaling $77.3 million (27%), and BMA Technical Services, Inc. holds three orders valued at $19.6 million (7%). A small long tail of two additional firms (AD HOC Research Associates LLC and Integrated Defense Applications LLC) account for less than 5% combined. All customer orders originate from the Army Test and Evaluation Command.

The vehicle operates under a mixed set-aside structure: 42% of task orders (eight) are designated Total Small Business set-aside, while 58% (eleven) carry no set-aside designation. Recent awards issued in 2025 predominantly under small-business set-aside, reflecting customer preference for small-business support on ongoing AEC operations. Typical task-order ceilings range from roughly $8.6 million to $62.1 million, with performance periods extending through 2028. Task orders fund missile defense analysis and testing, soldier evaluation, aviation-fires evaluation, command-control-communications-cyber-intelligence-surveillance-reconnaissance (C5ISR) evaluation, and cybersecurity technical evaluation for the Combatant Command Cyber Task Force.

The U.S. Army Evaluation Center, is responsible for all assigned developmental and independent operational evaluation of Army materiel, information and acquisition systems. AEC is a subordinate activity of the U.S. Army Test and Evaluation Command (ATEC), the Army's independent Operational Test Agency (OTA), developmental tester, and evaluator. AEC requires engineering and test support services across all AEC Directorates and Divisions. These services will perform a wide variety of tasks related to the Test and Evaluation programs at AEC. Contractor support will be required primarily at APG, MD, but may also be required at other locations on a temporary duty basis.
