1. From the title, "nuke drones" implies drones which are nuclear powered. The drones they refer to are torpedoes with nuclear warheads rather than nuclear power.
2. Torpedoes are torpedoes and NOT drones. If I fire a torpedo, I DON'T want it back. If I launch a drone, I would prefer to get it back.
3. Supposedly, these nuclear tipped torpedoes "... could be detonated underwater sparking 300ft high waves which could devastate coastal cities. Really? As slo-Joe would say, "Come on man."
4. A two megaton warhead exploding inside the 100 fathom curve might raise a wall of water 300 ft high but anything that close will be destroyed anyway. It takes a lot of energy to move enough water to 'destroy a city'. Energy levels drop off with the square of the distance. The math just doesn't work.
5. "And Putin has boasted its torpedoes can completely destroy coastal targets more than 6,000 miles away." Even an EXTREMELY long range torpedo has a range less than 20 nautical miles. That means the sub has to carry them the first 5,980 miles. That is the weak link. These 70kt torpedoes aren't going to sneak up on anyone. Stealth they aren't.
6. If indeed these 'nuke drones' have a much longer range, and they are going to remotely control these puppies over any appreciable distance I would love to hear how they plan to do it.
Calling a submarine a "city killer" because it carries 'nuke drone' torpedoes which can raise '300 ft high' waves which could devastate a city is stretch of a stretch of a stretch. Facts are rather inelastic.
Cutting undersea cables is a lot harder than you would think. It can be done but it isn't easy. Cut a fiber optic cable and it is a trivial exercise to know where the cut is. This is not conclusive to successful clandestine operations. Even if you cut one, other cables would pick up the load.
On a separate matter, I thought the size of the props looked rather small to push a sub of that size through the water quietly at any reasonable cruising speed. I would want larger slower turning props myself.
This list should not be considered all inclusive. I just got tired of dealing with it.
