Flightsafety Defense Corporation

Flightsafety Defense Corporation, doing business as FSI - Defense, is a Berkshire Hathaway subsidiary providing military aviation training, simulation services, and courseware development to the Department of Defense and allied partners as a prime contractor (93% of recent awards) and, increasingly, as a subcontractor on larger defense primes. The company competes full-and-open with no set-aside designations across its federal portfolio. FSI - Defense is headquartered in Fort Worth, Texas, and operates as a for-profit corporate entity under parent company Flightsafety International Inc.

FSI - Defense's capability portfolio centers on instructor-led pilot and aircrew training, flight simulation device operation and sustainment, courseware development, and technical support for military aviation platforms. Recent representative work includes a $15.03 million Naval Air Warfare Center delivery order (July 2026) for pilot training services at Fort Worth with completion through June 2027; a $59.6 million Aeronautical Systems Center definitive contract (July 2023) for Japan Air Self-Defense Force KC-46 aircrew training system development running through April 2026; and a $14.7 million Naval Air Warfare Center delivery order (July 2025) for Navy pilot training instructor services at Milton, Florida. The company also delivers recurring international partner training — multiple task orders supporting KC-46 pilot and boom operator qualification and refresher training for Japan through the Air Education and Training Command, with cumulative values in the low millions across individual orders.

Customer concentration is heavily skewed toward DoD aviation training programs. The top five customer organizations by award count account for 88% of awards: the Department of the Navy (154 awards across Naval Air Systems Command, Naval Air Warfare Center, and other Navy commands) dominates volume, while the Department of the Air Force Materiel Command Aeronautical Systems Center (24 awards, $54.97 billion combined potential value) anchors the dollars-by-value ranking — a significant divergence signaling a small number of very large aircraft training system development and sustainment contracts anchored at ASC. The Department of the Army Acquisition Support Center PEO Simulation, Training and Instrumentation ranks second by value at $17.56 billion across five awards. The Department of the Navy Naval Air Systems Command Naval Air Warfare Center places 20 awards with $4.83 billion potential value, reflecting sustained Navy pilot training operations.

FSI - Defense holds positions on four named DoD training system vehicles. The largest by task-order activity is a Navy Basic Ordering Agreement (N6247486D1400) with 138 task orders; the source does not provide a ceiling value. The Air Force contract FA300220D0005 carries 29 task orders and $4.3 million combined potential value. The Training Systems Acquisition III (TSA III) vehicle generated 12 task orders worth $5.5 million. TSA IV — the $32.5 billion Air Force Training Systems Acquisition IV multiple-award IDIQ awarded June 2023 with performance through May 2031 — is the flagship vehicle, supporting courseware development, instruction delivery, and training system sustainment across Air Force aviation programs; the source documents task-order activity but does not enumerate total orders under TSA IV. The Navy Fielded Training Systems Support V (FTSS V) contract, awarded July 2022 with a $2.51 billion ceiling through August 2030, supports Navy and non-Navy aircrew and maintenance simulator operations and instructional services worldwide, with performance at facilities including Orlando, Florida. FSA - Defense also holds a GSA ASTRO master GWAC position with a $3.5 million ceiling through November 2031, used for platform-related training and technical support services.

Activity has been steady at 10–17 awards per year over the past five years, with three awards documented in 2026 year-to-date. Five awards (combined potential value $1.75 billion) face ultimate completion within the next twenty-four months, representing recompete exposure concentrated in training system sustainment contracts. The source notes the Navy Fielded Training Systems Support V contract ceiling at $2.51 billion, though the recompete value is a subset.

FSI - Defense operates primarily as a prime contractor (93% of awards) and does not systematically rely on subcontractor teaming; across SCI-reportable prime service contracts, average sub-hours share is 0 percent, indicating FSI - Defense builds its own delivery capability. The company does subcontract to larger defense primes on a selective basis — named recent sub work includes multiple Boeing C-17 training system support tasks (December 2023 through December 2025), a Rockwell Collins Simulation & Training Solutions E2D weapons system trainer procurement sub-award (May 2025), and flight school training support services as a sub to General Dynamics Information Technology (March 2025 and April 2024). These sub roles center on training system integration, instruction support, and courseware development rather than prime aircraft manufacturing or major platform ownership.

SCI-reported invoicing on service contracts above the $150,000 threshold is zero across FY2022–FY2025, reflecting that the majority of FSI - Defense's federal work is classified as products or goods (training devices, simulation systems, courseware, and instructional materials) rather than time-and-materials or labor-hour service contracts subject to SCI reporting. The company's FTE trajectory in SCI records shows minimal labor content in reported records: 0.0 FTEs in FY2022–FY2023, climbing to 36.4 FTEs in FY2024 and declining to 18.5 FTEs in FY2025. This low SCI footprint does not reflect FSI - Defense's total federal workforce; it captures only a narrow slice of labor-intensive services above the reporting threshold. The company's actual federal staffing and revenue are substantially larger, concentrated in fixed-price delivery of simulation systems and training courseware.
