EL SEGUNDO, Calif.–(BUSINESS WIRE)–FDH Aero (“FDH”), an aerospace and defense products distributor serving aircraft production and aftermarket supply chains, announced today it has acquired Unical Defense, LLC (“UDI” or “Unical Defense”), a global provider of aftermarket component parts and logistics services for military aircraft, from affiliates of UDI’s founders.


Founded in 2015 and based in City of Industry, CA, Unical Defense provides its global defense customer base with a comprehensive aftermarket services solution for parts procurement and repair management. Serving more than 600 customers across the U.S., Asia, and EMEA, UDI has become a supplier of choice for leading government contractors, military fleet managers, and defense procurement divisions.

“We are excited to partner with the entire UDI team to support them at this inflection point in the company’s growth trajectory,” said Scott Tucker, CEO of FDH Aero. “We believe that bringing UDI into the FDH family complements and accelerates our broader strategic priority of growth in the global defense aftermarket. This acquisition further reinforces our commitment to high-touch customer service and expands our supplier partnership strategy.”

“FDH is an ideal fit for UDI as we continue to grow and invest in the business,” said Alice Zhang, existing leader of UDI and incoming Vice President of FDH’s Aftermarket Defense division. “With the strength of FDH’s existing inventory and long-term supplier OEM relationships, UDI will be able to broaden its ability to serve U.S. and international customers while maintaining the same level of quality and service that our customers have come to expect from us.”

Unical Defense is FDH’s tenth acquisition, and eighth completed since Audax Private Equity invested in the company in 2017.
