Defence Minister Rajnath Singh today received India's first-ever Rafale aircraft. The aircraft came with tail number 'RB 001'. 'RB' on the aircraft's tail stands for initials of Air Chief Marshal Rakesh Bhadauria, who took over as IAF chief on September 30. Bhadauria was the deputy chief of Indian negotiating team that finalised the deal to buy 36 Rafale fighter jets.
