ITT Electronic Systems said Wednesday that its Communications Systems business delivered its 500,000th Single Channel Ground and Airborne Radio System to the U.S. Army.

The company, which has operations in Fort Wayne, said it has developed, manufactured and supported six generations of continually improved SINCGARS radios since the first radio was delivered in 1988.

The radio system provides secure voice and data communications capability to Army tactical units, and ITT bills it as "the most prolific tactical radio system in the world."
