Subhab Phongsakornsathien

Subhab Phongsakornsathien, a Thai-based sole proprietorship, supplies facility modification, security infrastructure, and CCTV equipment services to the U.S. Navy's Chief of Naval Operations as a prime contractor on direct-award, full-and-open purchase orders with no set-aside designation. The vendor is registered in SAM.gov and operates from Samut Prakan, Thailand, serving U.S. military installations throughout the Asia-Pacific region.

The vendor's federal footprint is entirely concentrated with a single customer: the Department of the Navy's Chief of Naval Operations accounts for all ten awards in the source data, representing the full $90 thousand in combined potential value. All ten awards are prime purchase orders issued between May 2024 and February 2026, with no subcontract activity. The work centers on three capability areas. Security infrastructure dominates the portfolio — three awards for CCTV equipment provision and maintenance, two for access control system relocation and reinstallation, and one for security CCTV installation at a mail room. Facility modifications comprise two awards: room renovations and structural construction such as a roof covering for Building A's walkway and electrical cabinet. A single equipment provision award covered five ViewSonic displays. The largest individual contract is a $32.4 thousand firm fixed-price purchase order awarded September 25, 2025, for CCTV system service maintenance and installation, with ultimate completion December 30, 2025. A $20.6 thousand award issued January 30, 2026, for access control support at the Joint Military Assistance Group Thailand facility is the most recent. The remaining awards fall in the $2.4 thousand to $7.9 thousand range and reflect ad-hoc facility and security engineering work at Navy installations in Thailand.

Activity has declined from six awards in 2024 to two each in 2025 and 2026, suggesting a fluctuating work pipeline rather than steady growth. The vendor competes exclusively on full-and-open terms with no set-aside posture. All work is performed directly by Subhab Phongsakornsathien with no subcontractors involved, indicating the vendor operates as a local, independent service provider for Navy facility requirements in-country rather than as part of a broader prime teaming structure or federal supply chain.
