STS Systems Defense LLC

STS Systems Defense LLC, an Alaska Native Corporation-owned SBA 8(a) certified small disadvantaged business headquartered in San Antonio, Texas, provides engineering services, cyber integration support, and facilities management to the Department of Defense as a prime contractor on sole-source 8(a) awards (86% of recent awards) and as a subcontractor to defense primes. The vendor operates as a subsidiary of Bristol Bay Government Services Group, LLC, also an Alaska Native Corporation-owned firm, and competes predominantly under 8(a) sole-source set-asides across Air Force and Navy programs.

STS Systems Defense's customer concentration is heavily skewed toward Air Force logistics and maintenance commands. The top five agencies account for 100% of combined potential value across 43 awards, with Air Force Materiel Command's Ogden Air Logistics Complex anchoring $140.7 million (11 awards) and Air Force Materiel Command proper at $122.9 million (15 awards). The Naval Air Warfare Center contributes $66.2 million across seven awards, and the Aeronautical Systems Center carries $25.1 million. This concentration reflects the vendor's core mission: engineering support for depot industrial plant equipment (DIPE) systems, F-16 cyber integration, avionics integration and installation, and facilities preparation at Hill Air Force Base, Randolph Air Force Base, and Naval Air Warfare Center installations in Fallon, Nevada and San Antonio, Texas.

The vendor operates under three major indefinite delivery contracts that fund the vast majority of recent activity. An $97.5 million single-award 8(a) sole-source IDC with Air Force Materiel Command (September 2023 through September 2028) for depot equipment engineering services has generated 20 task orders totaling $56.2 million, including a $21.6 million firm-fixed-price definitive contract to design and construct paint booths at Hill Air Force Base (awarded September 25, 2025, completion November 18, 2027), a $20.3 million cost-no-fee delivery order for paint booth procurement and facility modifications supporting Reversion Off-Equipment Depot activation (awarded August 26, 2025, completion June 8, 2027), and numerous smaller delivery orders for industrial equipment procurement and installation ranging from $2,504 to $6.8 million. A $99.999 billion single-award 8(a) sole-source IDC with Air Force Materiel Command (January 1, 2024 through February 17, 2029) funds F-16 system cyber integration support, with task orders including a $5.159 million delivery order for F-16 cyber integration through February 2026. A $58.8 million single-award 8(a) sole-source IDC with Naval Air Warfare Center (April 30, 2025 through April 30, 2030) covers F-5 and F-16 avionics integration and installation services, with recent task orders including an $83.987 thousand delivery order for F-16C REDNET validation on 87-series aircraft (awarded February 2, 2026, completion February 1, 2027) and a $3.258 million delivery order for procurement and supply support (awarded September 28, 2025, completion September 27, 2026).

Activity has accelerated sharply — one award in 2021, five in 2023, eleven in 2024, and twenty-two in 2025 — reflecting the vendor's leverage of its three large IDVs into consistent task-order volume. Thirteen awards with combined potential value $68.7 million reach ultimate completion within the next twenty-four months, exposing the vendor to near-term recompete risk on active DIPE and cyber-integration task orders that will conclude in late 2026 and 2027.

Across SCI-reportable federal service contracts (a subset covering invoiced activity above the $150,000 threshold), STS Systems Defense reported $1 million in invoiced revenue in FY2024 across 2.6 FTEs on prime contracts, with median government-paid rates around $99.39 per hour and senior labor pricing through $178.91 per hour. SCI data shows the vendor subcontracts approximately 31% of contractor hours on prime contracts and names one subcontractor in SCI filings; however, the vendor's award descriptions cite multiple named subs performing specialized work — Hartwig, Inc. (machine tool distribution and rigging), Machine Tool Marketing Inc. (woman-owned small business, equipment procurement and installation), SDS Construction LLC (small disadvantaged business, equipment removal and disposal), Orbitform Group LLC, Arbor Controls & Testing, Inc., and OSI Vision LLC (8(a) certified, minority and veteran-owned, performing inventory and test-stand evaluation) — indicating a hybrid delivery model combining core engineering delivery with specialized subcontractor sourcing for equipment procurement and installation services. The vendor also operates as a named subcontractor to Peraton Enterprise Solutions LLC (software engineering services) and STS Government Solutions, LLC (a related entity performing civil engineer support, dive locker and maritime maintenance, and administrative services at Fort Hood and Air Force Cyber installations).

STS Systems Defense's positioning as an Alaska Native Corporation-owned 8(a) firm with three strategically valuable indefinite delivery vehicles in the Air Force and Navy logistics ecosystem has generated consistent sole-source award authority and deep integration into critical depot and aircraft modernization programs, though the steep concentration in Hill Air Force Base–centric DIPE work and F-16 cyber integration creates single-platform dependency.

SSD provides professional and technical engineering services for depot logistics operations, Information Systems, cyber Security, weapon system management, enterprise information systems, program management, Information technology, software development, database management, data analytics, research, special operations mission support, facilities, contracting, financial, and human resource management augmentation for DoD and other federal agencies.
