BENGALURU — Eurocopter says it will establish a production facility in India to manufacture its AS550 C3 Fennec helicopters if it wins a contract to supply the helos to India’s army and air force. The European company is vying with Russia’s Kamov 226 Sergei for an estimated $2 billion deal to supply 197 helicopters to the Indian defense forces. Of the 197 helos, the Army is likely to get 133 and the Air Force 64.
