Well, it looks like the on again off again deal between Russia and India to lease nuclear attack submarines is on again.
The Nerpa, which was originally the subject of the deal until an accidental discharge of the fire fighting system killed 20 people, is no longer believed to be a part of the deal, though a sister ship (Project 971 “Akula” class boats), or perhaps more than one sister ship, might be a part of the deal.
