Advanced Simulation Technology, Inc.

Advanced Simulation Technology, Inc., based in Herndon, Virginia, is a small business prime contractor (86% of recent awards) and subcontractor supplying voice over IP communications systems, simulation software and hardware, and training technologies to the Department of Defense. The vendor operates full-and-open, with no set-aside designations across its prime footprint, though occasional small business set-asides appear in the subcontract pipeline.

The vendor's capability portfolio centers on proprietary audio and communications systems branded as Voisus, Telestra, and SERA, marketed as modular, networked platforms for military training and simulation environments. Voisus delivers speech recognition, text-to-speech, environmental sound generation, and record-and-play functionality for combat information center trainers, aircrew systems, and weapons system simulators. Telestra provides audio systems and runtime licenses for flight simulators and maritime training platforms. SERA supplies automated role-player artificial intelligence to fill training positions when human operators are unavailable. Representative prime work includes a $900 million indefinite-delivery contract with the Air Force Life Cycle Management Center's Architecture and Integration Directorate (awarded June 2023, ultimate completion November 2027) to develop engineering, design, and simulation capabilities across synthetic environments; a $707,935 sole-source purchase order from Naval Sea Systems Command (June 2023) for 21 client positions, 7 instructor stations, and associated hardware for combat information center training at Naval Surface Warfare Center Dahlgren Division; a $410,837 purchase order from Air Force Materiel Command Aeronautical Systems Center (September 2022) for Voisus communication radio interface software performed in Universal City, Texas; and a $376,155 sole-source award from Naval Sea Systems Command (November 2021) for 21 Combat Information Center client position units and one EW sonar position unit compatible with existing systems at Herndon, Virginia.

Customer concentration is extreme. The Department of the Air Force alone accounts for 27 awards and $900.3 million in combined potential value (97% of the vendor's total portfolio), overwhelmingly anchored by the Air Force Life Cycle Management Center IDIQ. Naval Sea Systems Command and Naval Air Warfare Center account for 126 awards but only $10.7 million combined potential value — a sharp divergence between award count and dollar concentration. This portfolio composition reflects the vendor's position as incumbent for narrow-fit, sole-source communications and simulation hardware and software renewals across Navy training programs, plus dominant placement on the Air Force's flagship engineering and synthetic environment vehicle. The 47% of awards represented by the top five customer agencies leaves a tail of 66 distinct agencies served, but with minimal dollar presence outside Navy and Air Force buys.

Advanced Simulation Technology, Inc. sits as a prime on the $900 million Air Force Life Cycle Management Center Architecture and Integration Directorate IDIQ (multiple award, no set-aside, base ordering period five years with option to extend five additional years). Task orders under this vehicle fund capabilities briefing and rapid prototyping work. The vendor also appears on the Federal Supply Schedule (GSA IT Software — GS35F0416N), where 71 task orders have generated $1.6 million combined potential value, and on GSA OASIS UR (Pool 4). Navy BPAs and IDIQs generate smaller order volumes — six task orders under Indefinite Delivery Contract N0001923D0010 and similar counts on single-award Navy vehicles — but reflect routine maintenance and sustainment ordering rather than competitive procurement activity.

Activity has grown modestly over the past five years — from 12 awards in 2022 to a peak of 35 in 2025 — with 2026 showing only 10 awards in the two months of available data through August 13, 2026. The recompete cliff in the next twenty-four months presents minimal exposure: only seven awards worth $709 thousand face ultimate completion, suggesting the vendor's larger IDIQ and long-term sustainment contracts carry option years or renewal pathways that extend beyond the twelve-month window.

In its subcontractor role, Advanced Simulation Technology, Inc. delivers Voisus software, Telestra audio systems, and software/information assurance maintenance to Boeing, Lockheed Martin, Rockwell Collins Simulation & Training Solutions, Science Applications International Corporation, CAE USA, and others. Recent sub work (2024–2026) includes P-8 Poseidon aircrew training device upgrades and fleet release engineering for Boeing; F-35, F-16, Apache audio systems, and distributive battle management node communications for Lockheed Martin; E2D weapons system trainer and flight simulation manufacturing support for Rockwell Collins; and modeling and simulation development for SAIC against GSA OASIS UR and Air Force TENCAP programs. The subcontract stream reflects ASTi's role as a specialized audio and communications component supplier to large prime system integrators rather than as a full-solution provider in that channel.

Advanced Simulation Technology, Inc. competes predominantly in full-and-open procurement, with rare small business set-asides despite its small business status. Its competitive posture relies on sole-source justifications grounded in proprietary systems fit and compatibility with existing incumbent infrastructure — a defensible position for software and hardware renewals across entrenched Navy training platforms and a less sustainable one in new-development or rebid scenarios. The narrow product specialization, extreme customer concentration in the Air Force IDIQ, and dependence on sustainment ordering create revenue stability but limit diversification and growth optionality outside existing platforms.
