About the company
Kaes LLC Kinetic Engineering Aerospace Sciences Division operates as a small business prime contractor (9% of recent awards) and predominantly as a subcontractor (91%) delivering aerospace engineering services, structural analysis, and aircraft sustainment support to the Department of the Navy. The company is headquartered in St. Augustine, Florida, operates as a for-profit limited liability company, and holds a SEAPORT-NXG indefinite delivery contract with Naval Sea Systems Command valued at four billion dollars with a January 1, 2029 expiration.
The Navy dominates Kaes LLC's customer concentration by both volume and dollar value. Naval Air Systems Command accounts for 20 awards (97% coverage across the top customers), Naval Supply Systems Command holds 7 awards, and Naval Sea Systems Command anchors the potential-value ranking with 2 awards carrying the four billion dollar SEAPORT-NXG ceiling. A single $238,815 Small Business Innovation Research Phase I contract from Naval Strategic Systems Programs for feasibility study work on an innovative defense concept, awarded November 13, 2025, represents the company's most recent prime award. The Air Force carries 4 awards split between Material Command and the Lifecycle Management Center at Hill Air Force Base.
Kaes LLC's subcontractor footprint reveals specialized aerospace engineering and aircraft sustainment labor delivery. Fleet JV LLC is the dominant prime partner, with 16 sub awards from 2023 through 2025 covering structural analysis, T-45 and F/A-18 aircraft support, V-22 helicopter logistics, adversary training support, and maintenance and repair operations labor. Southwest Research Institute accounts for 4 sub awards providing structural engineering and aging-aircraft analysis support on A-10 and aging weapon systems projects. The Boeing Company received 8 sub awards in November 2025 for F/A-18E/F and EA-18G modification aerospace support work including horizontal stabilizer, aileron assembly, and wing landing flap labor. KBR Wyle Services received 1 sub award in February 2024 for F/A-18 and EA-18G reliability and service life extension engineering analysis and testing. Work is performed in St. Augustine, Florida with task orders flowing under the SEAPORT-NXG parent vehicle and subordinate basic ordering agreements and indefinite delivery contracts.
Activity has grown sharply — 7 awards in 2023, 8 in 2024, and 19 through mid-2025 — driven by the January 2025 SEAPORT-NXG IDC award and the March 2025 minimum-guarantee task order draw. Combined potential value across all 34 awards (prime and sub) reaches four billion dollars, though combined dollars obligated stand at $31.8 million (1% of potential value), reflecting the early-stage obligation posture on the newly awarded IDC and the task-order delivery model. Service Contract Inventory reports only 2 SCI records (both as named subcontractor) covering 13.9 FTEs in fiscal 2022, a partial view that excludes the majority of Kaes LLC's federal aerospace services work. The vendor operates through a named subsidiary, Matanzas Engineering & Technology LLC, structured as a small business joint venture limited liability company.
