About the company
Engineering And Software System Solutions, Inc. Oklahoma Office Division, doing business as ES3, is an SBA-certified women-owned small business headquartered in San Diego, California (corporate parent) with operational divisions including its Oklahoma office in Midwest City, that operates exclusively as a prime contractor on federal delivery orders, IDIQs, and multiple-award vehicles spanning defense logistics, engineering services, and thermal spray component sustainment. ES3 competes across both unrestricted and set-aside vehicles; its recent prime-award portfolio breaks down to seven awards under General Services Administration OASIS+ variants (unrestricted, total small business set-aside, and women-owned small business IDIQs), two under Department of the Air Force programs (Rapid Sustainment Directorate Multi-Award Contract and Thermal Spray SBIR Phase III), and five under Oklahoma City Air Logistics Complex sustainment and logistics contracts.
Customer concentration is dominated by two customer rankings that diverge sharply on dollar magnitude. GSA Federal Acquisition Service leads by both award count (seven awards) and potential value ($1 billion combined), anchored almost entirely by ES3's seats on three OASIS+ vehicles awarded in 2024–2025: the OASIS+ Unrestricted IDIQ (April 2025), the OASIS+ Total Small Business Set-Aside IDIQ (December 2024), and the OASIS+ Women-Owned Small Business IDIQ (September 2024). The Department of the Air Force ranks second by potential value ($975 million) on only two awards, both the Rapid Sustainment Office MAC IDIQ ($975 million ceiling, awarded July 2024) and a $1 thousand kickoff delivery order. The Department of the Air Force Materiel Command Oklahoma City Air Logistics Complex rounds out the top three (five awards, $7 million combined potential value) focused on thermal spray dashboard maintenance and sustainment. Navy commands (Naval Air Systems Command and Naval Sea Systems Command) account for two awards each, including a $710.7 thousand delivery order from Naval Air Systems Command for C2 exhaust fan and mist eliminator hardware under the NAVAIR Equipment Procurement and Sustainment master contract (August 2025).
ES3 holds primary vehicle positions on OASIS+ (three separate set-aside and unrestricted IDIQs with multi-billion-dollar notional ceilings), the Air Force Rapid Sustainment Directorate Multi-Award Contract ($975 million), a single-award SBIR Phase III IDIQ with Oklahoma City Air Logistics Complex ($3.4 million ceiling through October 2027), and the ASTRO multiple-award vehicle through GSA FEDSIM ($3.5 thousand ceiling through November 2031). Task-order activity under these vehicles remains light — only one task order has been invoiced under the Rapid Sustainment Office MAC IDIQ, and two small orders under the NAVAIR EPaS vehicle — indicating ES3's recent vehicle acquisition has not yet translated into sustained task-order volume. Recent delivery orders include a $149.9 thousand thermal spray dashboard task order from Oklahoma City Air Logistics Complex (June 2026, completion February 2027), a $710.7 thousand C2 exhaust fan and mist eliminator from Naval Air Systems Command (August 2025, completion May 2027), and a $149.9 thousand small-business-set-aside purchase order from Oklahoma City Air Logistics Complex for Laboratory Information Management System (LIMS) procurement consultation (September 2024, completed March 2025).
ES3's capability footprint centers on aircraft component maintenance, thermal spray coating and restoration, equipment procurement consultation, and logistics engineering services for defense sustainment — particularly Air Force and Navy aircraft overhaul and readiness operations. Activity has been episodic (one award in 2021, two in 2023, five in 2024, two in 2025, one in 2026 year-to-date), reflecting ES3's recent aggressive vehicle acquisition across OASIS+ tiers. Two awards (combined potential value $861 thousand) face ultimate completion inside the next twenty-four months, exposing modest recompete risk; the bulk of ES3's potential value sits in multi-year OASIS+ and Air Force vehicles extending through 2029–2033. NAICS concentration runs toward Research and Development in the Physical, Engineering, and Life Sciences (seven awards) and Engineering Services (six awards), with secondary strength in machine tool and aircraft parts manufacturing and repair-shop equipment support. ES3 operates 100% as a prime contractor with no subcontract footprint in the source data.
