I notice that future Indian Navy frigate INS 
Tushil is 
, with her sister INS 
Tamala to follow in 2025. These frigates are interesting for a few reasons:
1. As the latest evolution of the Pr. 1135 
Burevestnik design lineage dating back to the Soviet Union. The order is Krivak -> Talwar (Batch I and II) -> Admiral Grigorovich -> Talwar (Batch III/IV).
2. The political circumstances in which these latest ships were birthed into being. 
Tushil and 
Tamala were laid down for the Russian Navy as 
Admiral Grigorovich-class frigates 
Admiral Butakov and 
Admiral Istomin respectively in 2013. They were orphaned under construction when Ukraine refused the supply of gas turbines following Russia's annexation of Crimea. The project was subsequently revived with India as the new customer for both engines and ships, still to be completed at Yantar shipyard, Kaliningrad.
3. Although India will undoubtedly continue to rely on foreign partners for supplying certain systems and components, 
Tushil and 
Tamala are very likely to be the 
last major combatants constructed abroad for the Indian Navy.  A further two ships in the class are under construction at Goa shipyard, the first of which, INS 
Triput, was launched earlier this year.
