Though there are no clear proofs, due to amount of secrecy involved, but its widely believed in defense circles that India did buy Six batteries of S-300PMU in the early 2000s, which was later upgraded to S-300VM standards. The upgraded system is supposed to have anti-SRBM/MRBM capabilities with a supposed range of 250Kms. The rumored deployment is around Mumbai and New Delhi, now to be taken over with PAD/AAD.
