What Modern Technology Solutions does

Modern Technology Solutions, Inc. (MTSI) is a privately held, 100% employee-owned engineering services and technology solutions company headquartered in Alexandria, Virginia, founded in 1993 by two retired Air Force engineers. The company supports the Department of Defense, Intelligence Community, Federal Civilian agencies, and selected commercial aerospace customers across mission areas spanning missile defense, hypersonics, space, cyber, autonomous systems, aviation, and test and evaluation. MTSI operates a portfolio of seven core capability areas — Software Engineering, Autonomy & AI, Systems Engineering & Integration, Mission Assurance & Cybersecurity, Acquisition & Program Management, Modeling Simulation & Analysis, and Test & Evaluation — delivered through prime positions on 175+ active contracts across vehicles such as IAC MAC, GSA MAS, Seaport NxG, OASIS Plus, HEMISPHERE, Tradewinds AI, and TETRAS II.

The company differentiates through a deep portfolio of proprietary tools and patented methods, including AFSIM-based multi-domain simulation, HyperRADS for hypersonic multi-physics analysis, URAMS for cyber-physical risk assessment, HiRTSS for high-rate thermal and signature modeling, MASST for space architecture analytics, SAFE for autonomous platform certification, the patented A3R autonomous air-to-air refueling concept, RATS for affordable airborne training targets, and the recently launched AAIRAF for AI risk and assurance. Approximately 3,000 employee-owners, a 95%+ retention rate, and 100% recompete win rates underscore an unusual talent and customer-retention profile in a federal services market where continuity and cleared personnel are decisive.

MTSI generates revenue primarily through time-and-materials, cost-plus, and fixed-price professional services contracts with U.S. government customers, supplemented by commercial aerospace and eVTOL flight test work via AFWERX and similar pathways. The company holds ISO 9001:2015 certification, operates 15 offices across 12 states, and pursues growth via new contract vehicles (including Mentor-Protégé joint ventures for small-business set-asides), targeted geographic expansion (Wright-Patterson 2026 expansion), and AI-enabled productization of capabilities such as HADES and AAIRAF.
