Telephonics Corporation

Telephonics Corporation. It is a prominent American aerospace and defense contractor specializing in advanced communication, identification, and sensor systems. Founded in the early 20th century, the company evolved from manufacturing telephone components to becoming a critical supplier for major military and commercial aviation programs. Its technologies are integral to platforms used by the United States Department of Defense, NASA, and global commercial airlines, emphasizing secure data links and air traffic management solutions.

History

The company was established in 1933 by inventor William J. Meise in Brooklyn, initially producing components for the burgeoning Bell System and early radio equipment. During World War II, it pivoted to support the war effort, manufacturing crucial components for military communication systems. In the postwar era, it expanded into the aerospace sector, developing identification friend or foe (IFF) systems and moving its headquarters to Farmingdale, New York. A significant milestone occurred in 1987 when it was acquired by the Griffon Corporation, providing substantial capital for growth and diversification. Throughout the Cold War and into the 21st century, it has been a key player in advancing avionics for programs like the Boeing 737 and various United States Navy aircraft.

Products and services

Its portfolio centers on sophisticated electronic systems for command, control, and surveillance. Core products include integrated communication systems for military aircraft, such as secure voice and data links used on the Sikorsky SH-60 Seahawk and Boeing P-8 Poseidon. The company is a leader in air traffic management technologies, providing Mode S transponders and traffic alert and collision avoidance system (TCAS) equipment for global airliners. Its radar and sonar systems are deployed on naval vessels for surface search and undersea detection. Additionally, it manufactures advanced intercom systems for armored vehicles and specialized telemetry equipment supporting NASA and United States Air Force test ranges.

Corporate structure

Operating as a wholly-owned subsidiary of Griffon Corporation, it functions as a key segment within Griffon's defense electronics portfolio. Leadership has historically included figures like Kenneth C. Dahlberg, who later led Science Applications International Corporation (SAIC). The organization is divided into focused business units handling communications systems, surveillance and sensor solutions, and advanced information systems. Its primary research, development, and manufacturing facilities are located in Farmingdale, New York, and Huntington, New York, with additional operational sites across the United States and international support offices. This structure enables close collaboration with prime contractors like Lockheed Martin and Northrop Grumman.

Acquisitions and subsidiaries

To bolster its technological capabilities and market reach, it has engaged in strategic acquisitions. A major purchase was Interstate Electronics Corporation (IEC), a specialist in GPS and weapon systems test instrumentation, which expanded its footprint in missile defense and space launch support. It also acquired the communications division of Esterline Technologies, enhancing its portfolio in cockpit voice recorders and avionics. These subsidiaries are integrated to provide comprehensive system solutions, particularly for the United States Army and United States Strategic Command. The integration of these entities has solidified its role in critical national security infrastructure.

Major contracts and projects

It holds longstanding contracts with major defense and aviation entities. A flagship project is supplying the Common Cockpit avionics suite for the entire fleet of United States Coast Guard helicopters, including the Sikorsky MH-60 Jayhawk. It provides acoustic sensor systems for the Virginia-class submarine program and AN/UPX-44 interrogator systems for the United States Navy's surface fleet. In commercial aviation, its transponders are certified on aircraft from Airbus and Boeing, supporting global air traffic control modernization. The company also supports the Federal Aviation Administration's Next Generation Air Transportation System (NextGen) and international programs like the Eurofighter Typhoon.
