Communications & Power Industries (CPI) on Monday said it has completed its acquisition of the ESSCO business unit of L3Harris Technologies [LHX], adding to its radome business.

Terms of the deal, which was first announced in September, were not disclosed.

ESSCO, which has about 90 employees, was part of L3Harris’ Aviation Systems segment. The business unit manufactures metal space frame ground radomes and specialty radomes and composite structures, primarily for government and defense customers.

CPI said the acquisition combines its expertise in airborne and shipboard radomes using high-performance, low-loss composite materials with ESSCO’s expertise in large radio frequency (RF) ground structures and advanced alternative materials.

ESSCO, which is based in Massachusetts, will become part of CPI’s Radant Technologies Division. CPI said the deal will allow it to offer its customers a comprehensive portfolio of ground-based, airborne and shipboard radomes ranging in size from two inches to 61 meters in diameter supporting defense and communications applications.

“In 2021, we have diversified and deepened the portfolio of RF components and systems that CPI provides to government, military and commercial customers through the acquisitions of the TMD Technologies business in July and the ESSCO business in November,” Andy Ivers, president and chief operating officer of CPI, said in a statement. “These acquisitions complement CPI’s existing businesses and capabilities, and provide CPI with significant opportunities for future growth as we continue to enhance the range of products and services we provide customers.”

ESSCO’s senior management will remain in place.

Houlihan Lokey served as L3Harris’ financial adviser on the deal.
