→DoD accounts for 85% of NAICS 488190 spending ($4.6B of $5.4B) — driven by aircraft sustainment contracts covering Army, Navy, Air Force, and Marine Corps fleets.
→DHS's $333M at 432 awards covers CBP Air and Marine Operations (AMO) — patrol aircraft, UAS, and helicopter maintenance — a more distributed and accessible segment than DoD.
→DOT's $274M covers FAA contract tower operations and air traffic support services — more accessible for smaller aviation service firms with regional footprints.
→Average award value of $1.18M suggests a mix of large PBL (performance-based logistics) contracts and smaller maintenance task orders — competitive opportunities at multiple tiers.
