Russia joins the race to supply light battle tanks to the Indian Army


Russia will field its Sprut-SDM1 light amphibious tank for the Indian Army’s upcoming tender for light tanks.


  • The project has received in-principle approval and is planned to be procured under the ‘Make-I’ acquisition category of the Defense Acquisition Procedure (DAP)-2020.
    • ‘Make-I’ refers to government-funded projects while ‘Make-II’ covers industry-funded programs.
    • Make-I was involved in the development of big-ticket platforms such as light tanks and communication equipment with Indian security protocols.
  • This is in line with the ‘Make in India’ initiative.
  • The Acceptance of Necessity (AoN) from the Defence Acquisition Council is expected shortly.

Defense Acquisition Procedure (DAP) 2020: It enables the notification of a List of Weapons or Platforms that will be banned for import. It focuses on Foreign Direct Investment (FDI) in defense manufacturing and indigenization of the manufacturing prices. It also introduces several new ideas such as the need to incorporate artificial intelligence in platforms and systems, the use of indigenous software in defense equipment, and 'innovation' by startups and MSMEs (Micro, Small, and Medium Enterprises) as new categories of defense acquisition.
