Training Support Systems Enterprise (TSS-E)

Department of the Army Materiel Command Mission and Installation Contracting Command Fort Eustis awarded the Training Support Systems Enterprise (TSS-E) Master IDIQ on July 7, 2023, with authority to place orders through July 6, 2028, leaving approximately 1 year 11 months of remaining ordering window. This $610 million shared-ceiling, multiple-award vehicle provides Live, Virtual, Constructive, and Gaming (LVC&G) integrated training and program support services to Army Headquarters, installations, commands including TRADOC, IMCOM, USARC, and ARNG Direct Reporting Units across CONUS and OCONUS locations. The vehicle carries no set-aside restrictions; award competition is unrestricted.

Ordering momentum has decelerated sharply. Twenty-four task orders were awarded over the vehicle's lifecycle, with ten orders each in 2023 and 2024, dropping to three in 2025 and one through early 2026. The most recent award issued on February 26, 2026. Combined task-order potential value stands at $39 million against the $610 million ceiling, with $22 million obligated (56% of combined potential value). Task-order scope spans role-player support for National Training Center exercises at Fort Irwin, Integrated Training Area Management (ITAM) support, training operations support at multi-installation bases, training support center warehouse and operations functions, grounds maintenance, and network administration for combat training center systems.

Calibre Systems Inc. and Fitt Scientific LLC dominate the prime field, holding six and five orders respectively for a combined $25.5 million of potential value—roughly 65% of the portfolio. Check Defense LLC, Janus Research Group LLC, Applied Training Solutions LLC, and a small group of additional primes round out the nine contractors awarded. Two orders carried Total Small Business designations; the remaining 22 are unrestricted. Customer concentration is moderate: Department of the Army Training and Doctrine Command placed 14 orders ($7.6 million), while Installation Management Command Southeast and Southwest Regions placed 7 combined orders ($23.9 million). Task-order values range from $1 thousand minimum guarantees to $7.4 million ceilings, with typical durations spanning two to five years. Performance locations cluster at Army installations including Fort Irwin, Fort Liberty (formerly Fort Bragg), Joint Base Lewis-McChord, Fort Devens, and the National Training Center.
