About this vehicle

Written by GovTribe AI ·

The Department of the Army Materiel Command Research Development and Engineering Command established the Scientific, Technical, Engineering and Program Support Services (STEPSS) Master IDIQ on April 8, 2022, to provide research, development, test and evaluation, engineering, acquisition, and chemical and biological demilitarization support to the Army Combat Capabilities Development Command Chemical Biological Center (DEVCOM CBC) and other CBRNE defense agencies. Ordering authority extends through April 7, 2032, providing 5 years and 8 months of remaining procurement window against a combined potential value of $79.4 million.

Ordering activity has slowed materially after initial launch. The vehicle awarded 26 orders in 2022, then declined to 3 in 2023, 1 in 2024, and 3 in 2025. Most recent award occurred in September 2025. To date, $21.7 million (27% of combined potential value) has been obligated.

Awarded scope reflects the breadth of DEVCOM CBC operations: chemical and biological defense research and product development, modernization of chemical agent detection systems, toxicological and chemical sciences services, smoke and obscurant research, air monitoring and quality management, personal protective equipment laundry services, chemical and biological containment system operation and maintenance, and radiation safety programs. Most recent task orders involve technical data generation for non-traditional chemical warfare agents and laboratory services supporting the Chemical Test Division.

Competition remains concentrated. Excet, LLC holds 36% of awarded task orders by count and 51% by combined potential value ($40.8 million across 4 orders). Joint Research And Development LLC holds the second position with 2 orders valued at $21.3 million combined potential. Scitech Services Inc., Patricio Enterprises, Inc., and Battelle Memorial Institute each hold 2 orders. Twenty remaining awardees share limited activity. Approximately 88% of task orders carry no set-aside designation; 12% are small-business total set-asides.

Ordering is concentrated among Army programs, with 32 of 33 orders ($75.2 million combined potential value) funding Department of the Army Materiel Command Research Development and Engineering Command. Work is performed primarily on-site at Aberdeen Proving Ground and Edgewood Area, Maryland, with a smaller component off-site, and includes locations across CONUS, OCONUS, and combatant zones.
