About the company

Written by GovTribe AI ·

Protofab Engineering Inc. is a for-profit manufacturer that has been registered to receive federal contract awards since 2010. As a subcontractor, Protofab provides parts, materials, and services to prime contractors, mainly Northrop Grumman Systems Corporation, in support of various defense and armaments programs.

Specifically, Protofab has provided electronics, housings, covers, and other unspecified components for Northrop Grumman's HTVSF program. They have also delivered parts and services related to the PGK program under Northrop Grumman. Additional subcontracts have entailed armament systems components and materials for unknown systems. The subcontract descriptions indicate Protofab supplies structural housings and enclosures, along with more sophisticated electronics, to be integrated into broader weapons and defense systems by prime contractors like Northrop Grumman. Given the partnership with Northrop Grumman, it is likely Protofab's subcontracts ultimately support U.S. Department of Defense programs.
