It was a sensible idea not to invest money in producing all kind of outdated soviet stuff that Zorya Mashproekt was producing (concentrating instead on the projects needed for future ship classes), but that (unfortunately) meant that production of some of the older ship classes (mainly Krivak IV / Grigorovich and gepard class) could not be continued.
The simpler thing now would be to sell it to the Indians (only if they make a good offer)...
either completing directly in Kaliningrad or towing it to India and having the indians complete if they so prefer.
If the indians don't make a good offer... well Russia can still keep it mothballed until the Ukraine loses Nikolaev. Then they can complete it and sell it to Iran or Venezuela.
