BALTIMORE (AP) - Defense contractor Northrop Grumman Corp. said Monday it sold a manufacturing and marketing license on its ASR-12 air traffic control system to Indra, a Spanish defense and information technology company.
The terms of the deal were not disclosed.
According to the agreement, Indra cannot make or market the system in the United States, Northrop Grumman said.
Commercial airports use the system to monitor the approach, landing and departure of aircraft. Northrop Grumman said 135 airports in the U.S., as well as 18 airports in other nations, currently use the system.
Indra operates air traffic management systems in 40 countries, with Europe as its primary market.
