Engineering And Software System Solutions, Inc.

Engineering And Software System Solutions, Inc. (doing business as ES3), a woman-owned small business headquartered in San Diego, California, operates as a prime contractor (98% of recent awards) delivering advanced aerospace manufacturing, materials research, and engineering services to the Department of Defense with a concentrated focus on Air Force sustainment and modernization. ES3 competes primarily under total small business set-asides across its SBIR and STTR portfolio, though an increasing share of recent awards carry no set-aside designation, reflecting the vendor's capability maturation and positioning on broader defense programs including the newly awarded Missile Defense Agency SHIELD vehicle.

ES3's capability portfolio centers on specialized coating technologies, additive manufacturing, precision repair processes, and aerospace component restoration. Representative prime work includes a $13.3 million Phase III SBIR award from the Ogden Air Logistics Complex for magnetron sputtering system (MSS) restoration of landing gear component threads and keyways (September 2023); a $5 million Cost Plus Fixed Fee contract from the Air Force Research Laboratory for digital-twin framework development for additive manufacturing of continuous-fiber composites for attritable air vehicles (November 2022); a $3.06 million total small business set-aside from AFLCMC Robins for prototype development and qualification testing of the UT-1 Universal Towbar (August 2024); and a $3.3 million Phase III SBIR from the Air Force Sustainment Center for low-hydrogen-embrittlement zinc-nickel and cadmium plating processing development (March 2023). Recurring contract topics across the portfolio span thermal spray coatings, alternative plating chemistries (zinc-nickel, trivalent chromium substitutes), laser-based repair and drilling, robotic defastening, and landing gear system modernization. The vendor holds active GSA Schedule labor rates spanning technician and engineer roles from $83.28 to $270.58 per hour, with education credentials from high school through bachelor's degree and no security-clearance requirements listed.

Customer concentration is heavily Air Force—the top five customer entities account for 64% of awards by count and 79% by combined potential value. Warner Robins Air Logistics Complex leads on dollars ($466.9 million across 56 awards), followed by the Air Force Sustainment Center ($196.8 million across 49 awards) and Ogden Air Logistics Complex ($172.6 million across 59 awards). Recent activity shows declining trajectory: 26 prime awards in 2022 down to 3 in 2026 (through May), a pattern consistent with portfolio transition from research phases into fewer, higher-dollar Phase III and production contracts. Over the next twenty-four months, fourteen awards with combined potential value of $33.8 million face ultimate completion and therefore recompete exposure, concentrated among Air Logistics Complex contracts.

ES3's vehicle position centers on Air Force Materiel Command IDIQs. The Applied Technologies for Landing Systems (ATLAS) 2.5 contract carries 22 task orders totaling $53.5 million; Indefinite Delivery Contract INN06PC10437 holds 16 task orders valued at $61.9 million; Indefinite Delivery Contract FA825111D0001 supports 15 task orders at $25.5 million; and Indefinite Delivery Contract FA820106D0015 carries 24 task orders valued at $13 million. Most recently, ES3 was awarded a multi-billion-dollar ceiling Indefinite Delivery contract under the Missile Defense Agency's Scalable Homeland Innovative Enterprise Layered Defense (SHIELD) program on December 29, 2025, with an initial $500 task order placing performance in Huntsville, Alabama. The Defense Logistics Agency Aviation Blanket Purchase Agreement ($5 million ceiling, awarded November 2022 through March 2027) remains active for engineering services. Work under these vehicles spans firm fixed-price and cost-plus-fixed-fee arrangements across classified and unclassified defense systems development, prototyping, systems engineering, and production.

Subcontract footprint is minimal (2% of awards by count). Recent sub work includes repair and return of Chilean military assets under a Leidos prime (May 2026), horizontal stabilizer bearing transition work under Amentum (October 2025), and ground system technology development under Booz Allen Hamilton on an Army SBIR Phase III (December 2024). Amentum sub-awards spanning November 2024 involve direct parts, tooling kits, and special materials for aircraft component work.

The vendor's award portfolio weighted heavily toward Air Force research, development, and production work reflects ES3's specialization in solving aircraft sustainment challenges through advanced manufacturing innovation. NAICS concentration sits in Engineering Services (145 awards) and Research and Development in Physical and Engineering Sciences (97 and 57 awards respectively), with secondary exposure in manufacturing and IT services. PSC concentration mirrors this: Support Professional Engineering/Technical (68 awards), Maintenance/Repair/Rebuild of Aircraft Components (30 awards), and IT Systems Development (25 awards). The dominance of Air Force Materiel Command customers and the pronounced taper in award velocity after 2023 suggest ES3 has transitioned from high-volume SBIR Phase I and II activity into selective Phase III commercialization and production contracts, where dollar magnitude per award increases significantly but award frequency declines.
