A custom-made B777 aircraft, which will be used to fly the president, vice president and prime minister, has arrived in Delhi from the US on Thursday. Another custom-made B777 plane for the travel of VVIPs is likely to be received from Boeing at a later date. Officials said the total cost of purchase and retrofitting the two planes has been estimated to be around Rs 8,400 crore. During the travel of the VVIPs, the two B777 aircraft will be operated by pilots of the Indian Air Force (IAF). The B777 planes will have state-of-the-art missile defence systems called Large Aircraft Infrared Countermeasures (LAIRCM) and Self-Protection Suites (SPS). In February, the US agreed to sell the two defence systems to India at a cost of USD 190 million.
