Radar market heats up - particularly in Latin America and Asia

Demand for land-based surveillance radar will grow through 2008, says market researcher Frost & Sullivan. The total worldwide market for land-based surveillance radar grew from $636 million in 1998 to $691 million in 1999, and will continue for the next eight years, according to the Frost & Sullivan study "World Military and Commercial Land-Based Surveillance Radar Markets." Helping drive demand are efforts to modernize radar in Latin America and Asia - particularly in air traffic control and weather applications, the study says. Military radar users prefer active-array radar, which is expected to dominate military radar procurement for the next five to seven years, the study says.

Computer Sciences to develop air-control data link

Systems integrators at Computer Sciences Corp. in Falls Church, Va., are designing components for the Federal Aviation Administration's future Controller Pilot Data Communications Link, better known as CPDLC. Computer Sciences, which is working under terms of an $18 million FAA contract, will build and install the en-route data link, which will generate air traffic services data and send the data via digital air-to-ground communications to supplement voice-only communications. The program supports the FAA's Free Flight Program, which gives pilots the capability to make the most of airspace and reduce delays by giving them broader freedom than they have to day to fly direct routes. Computer Sciences experts will develop software, install the systems, and provide training. Teaming with Computer Sciences is Lockheed Martin Air Traffic Management in Rockville, Md.; Aeronautical Communication International in New York; Bloodworth Integrated Technology Inc. of Reston, Va.; Certification Services Inc. in Seattle; Crown Consulting Inc. in Washington; Joseph Sheairs Associates of Egg Harbor, N.J.; and Performance Technologies International of Reston, Va. - J.K.

Systems integrators from the Lockheed Martin Corp. Naval Electronics and Surveillance Systems division in Morristown, N.J., will design the battle-management electronics aboard the U.S. Navy's yet-unnamed CVN 77 nuclear-powered aircraft carrier. Lockheed Martin will work under supervision of the CVN 77's prime contractor, Newport News Shipbuilding of Newport News, Va. Lockheed Martin engineers will be responsible for improving the interoperability between the carrier's sensors, communications systems, aircraft control systems, armaments, and other electronics. "CVN 77 is the first step in the Navy's three-ship evolutionary strategy for developing the next class of carriers," says Irwin Edenzon, director of future carrier programs at Newport News Shipbuilding. "The CVN 77 warfare system will be the first building block the next class of carriers. Because of that, we'll work with Lockheed Martin to deliver an open-architecture, COTS-based system that will allow us to readily support and upgrade the system over its 50-year service life." - J.K.
