India has moved forward with plans to acquire five additional S-400 Triumf air defence systems from Russia after receiving a Bill of Quantities proposal from Moscow.
The original 2018 contract for five S-400 systems was valued at USD 5.43 billion, with the final unit of that order scheduled to arrive in November 2026.
The Cabinet Committee on Security will make the final approval decision once cost negotiations conclude and the Indian finance ministry provides a green signal.
