About this vehicle

The Army Materiel Command Army Contracting Command at Aberdeen Proving Ground established the Strategic Sources Services (S3) Master IDIQ on March 2, 2006, with a final ordering deadline of March 1, 2016—more than ten years past, making this vehicle inactive for new task orders. The combined potential value across 477 task orders totals $20.6 billion, with $16.74 billion obligated (81% of combined potential). Ordering activity declined sharply in the vehicle's final years: 45 orders in 2012, but only 7 in 2015 and 1 in 2016, reflecting the approach to the ordering cutoff.

Work spans Army command and control systems, intelligence and surveillance platforms, sensor development and integration, communications infrastructure, electronic warfare, force protection, and engineering support services. The most active customer, Army Materiel Command Communications Electronics Command, placed 199 orders valued at $11.14 billion combined potential. Army Contracting Command Aberdeen Proving Ground itself placed 90 orders worth $2.81 billion. Research Development and Engineering Command, PEO Intelligence Electronic Warfare & Sensors, and PEO Command Control Communications-Tactical collectively represent significant downstream demand. Task orders are overwhelmingly cost-plus-fixed-fee awards, with occasional firm-fixed-price and time-and-materials task orders; all 477 orders were unrestricted (no set-aside designations).

Competition concentrated among five primes holding 76 percent of awards by count: CACI Technologies led with 178 orders and $4.69 billion combined potential value; Mantech Advanced Systems International held 41 orders and $4.45 billion; Booz Allen Hamilton had 63 orders and $1.95 billion; Lockheed Martin Integrated Systems captured 40 orders worth $1.26 billion; and Viatech held 39 orders for $975.7 million. When ranked by potential value, General Dynamics Information Technology and Leidos entered the top tier, each with over $3 billion in combined potential across 18 and 27 orders respectively. Task orders ranged from sub-million-dollar efforts to individual mega-orders exceeding $600 million in ceiling value, with many orders in the $30–$200 million range. Work is performed at domestic Army facilities (particularly Aberdeen Proving Ground, Fort Belvoir, and CECOM locations) and overseas contingency operation theaters; recent late-life orders funded Distributed Common Ground System–Army capability insertion, expeditionary energy and sustainment systems, and legacy platform sustainment as the vehicle wound down.
