Castellum Inc. (CTM) announced on Friday that its subsidiary Specialty Systems Inc. (SSI) has secured a $66.2 million contract from the Naval Air Warfare Center Aircraft Division (NAWCAD) in New Jersey.

Agreement Components

The five-year deal covers logistics, engineering, and cybersecurity services for the Mission Operations & Integration (MO&I) Department, which supports aircraft launch and recovery systems used across Navy carriers and air-capable ships.

“It is an example that our targeted strategy to focus on full and open opportunities in our pipeline as we transition to a large business is working.” 

-Drew Merriman, COO, Castellum

Expanding Role in Naval Operations

Under the new agreement, SSI will provide ongoing support to NAWCAD’s Digital Engineering, Engineering Integration, and Logistics and Maintenance Integration divisions. The contract also covers work tied to the Department of Defense and foreign military programs.

The firm said the win strengthens its foundation for continued growth, both through expanded federal partnerships and investments in proprietary technologies.

“First our $103M+ win, which we announced in February, and now this $66M+ win in the Full and Open category amongst SeaPort contract holders, overcoming keen competition from a number of other very capable large businesses,” added Merriman. 

Castellum stock has lost over 48% in 2025 but gained over 586% in the last 12 months.
