Kastle Aviation, Inc.

Kastle Aviation, Inc., doing business as Kastle Aviation, is a woman-owned small business based in Burbank, California, that supplies specialized aviation and electrical components to the Department of Defense as a prime contractor on firm-fixed-price purchase orders, competing on a full-and-open basis with no set-aside designations applied across its federal award portfolio.

Kastle Aviation operates as a Subchapter S corporation and for-profit organization with a footprint concentrated in component manufacturing and distribution for military aviation and maritime equipment support. The vendor manufactures or sources fasteners (studs, rivets, setscrews, washers), electrical parts (connectors, plugs, resistors, capacitors, motor covers), mechanical assemblies (clamps, springs, shims, brackets), and specialized aviation components (brake armatures, synchro receivers, oil level sticks, distribution covers). Representative prime awards include a $98,730 firm-fixed-price purchase order from the Defense Logistics Agency (DLA) Aviation in August 2024 for oil level stick plugs; a $61,050 DLA Land and Maritime purchase order in April 2026 for 33 units of straight shafts; a $38,122.50 DLA Aviation order in June 2024 for distribution covers; and a $12,378.80 DLA Land and Maritime purchase order in March 2025 for electrical brackets. All work is performed in Burbank, California, with typical lead times of 30 to 60 days.

Customer concentration is extremely high and narrowly focused on defense logistics procurement. The top five funding agencies account for 91% of recent awards, dominated by the Defense Logistics Agency (DLA) Aviation (60 awards, $450 thousand combined potential value) and DLA Land and Maritime (36 awards, $255 thousand combined potential value). The Department of the Navy's Naval Air Systems Command (30 awards, $4 thousand) and Naval Supply Systems Command (26 awards, $35 thousand) contribute moderate volume with minimal dollar value, while the Department of the Air Force Materiel Command's Air Force Sustainment Center accounts for 11 awards totaling $10 thousand. Across the portfolio, 91% of awards flow through DLA's Aviation and Land and Maritime divisions, with the next-largest customer accounting for only 17% of that baseline.

Activity has accelerated in recent years: 4 awards in 2022, 3 in 2023, 7 in 2024, 17 in 2025, and 11 in the first seven months of 2026. The combined potential value across 180 lifetime awards is $774 thousand, with obligated dollars at $857 thousand (111% of potential value), indicating that actual invoiced revenue has exceeded posted ceiling values across the portfolio. Component manufacturing concentrates in Other Aircraft Parts and Auxiliary Equipment Manufacturing (44 awards), Motor and Generator Manufacturing (13 awards), Hardware Manufacturing (12 awards), Bolt/Nut/Screw/Rivet/Washer Manufacturing (11 awards), and Capacitor/Resistor/Inductor Manufacturing (11 awards) by NAICS classification; by PSC, the vendor clusters in Electrical Motors (13 awards), Miscellaneous Aircraft Accessories and Components (12 awards), Commercial Hardware (11 awards), Rivets (10 awards), and Electrical Connectors (10 awards). Kastle Aviation maintains no documented subcontract role and operates exclusively as a prime supplier on small-dollar component purchase orders to DLA and Navy logistics commands.
