America's Lockheed Martin said it won't sell its F-21 fighter jets to any country if India orders its 114 planes. Last month, the Indian Air Force issued an initial tender to acquire 114 jets at a cost of around $18 billion. The top contenders include Lockheed's F-21, Boeing's F/A-18, Dassault Aviation's Rafale, Eurofighter Typhoon, Russian aircraft MiG-35 and Saab's Gripen.
