Astronics AES‘s legacy dates back to 1958 in Seattle, Washington, where Electric Service Company “ELSCO” built the Bomarc missile test set for Boeing. In the 1960s, the company focused on growth in the small specialty power supply business, particularly items like rugged computer power supplies, windshield temperature controllers, and voltage detectors. In the 1970s, the company expanded its product line to include weapons release test sets for the F-111 and F-16. Product growth areas included aural warning systems, passenger address amplifiers, and ground fault systems. At this point Astronics AES moved to Redmond, Washington. During the 1980s, product offerings expanded further to system-level power and test systems, including a complete world-wide power system with back-up power for US Marine Corps aircraft, the B-1B weapons test system, and several commercial transport aircraft power conversion products. In the early 1990s, two new product lines were delivered - the cabin phone system for AT&T, and power systems for missiles. In the late 1990s, the company introduced its in-seat power system, EmPower®. In the first 5 years of 2000, Astronics AES moved to a larger building in Redmond, and introduced yet another product line - CorePower®, a complete power generation and distribution system for small aircraft. In early 2013, the company opened the doors of its new facility in Kirkland, Washington.
