The Boeing F/A-18E/F Super Hornet is a twin-engine carrier-based multirole fighter aircraft. The MMRCA contract represents a prime opportunity for US defence companies to gain a foothold in the Indian defence market, which is estimated to be about 100 billion in the next 10 years. Initially, the Request for Information (RFI) was not issued to Boeing, which decided to field the Super Hornet. The US Government allowed Boeing to participate in the RFI, and later gave permission for the Request For Proposal (RFP). However, any sale of aircraft would have to be approved by the US Congress.
