tango 1 posted a link in below thread about putins failed nuclear threat
the paper/blog mentions the Poseidon under water nuclear weapon having a 100 knots speed ?
my question what would be used to destroy it?
torpedo's are not that fast
head on shots would be hard to line up / |

Torpedos can be a lot faster than a 100kts, look up super cavitation. A lot of BS from Russian sources but there is some truth in there somewhere. I've not read much about the US/West developing the same technology but I guess they are, certainly nothing in service that uses it in the Royal navy. Also the 100kts speed for Poseidon is if it's launched close to its coastal target, if it gets fired across the width of the pacific then it will be approaching much slower. That's what I've read anyway. But bottom line? Yeah, it's going to be tricky to detect and kill if its running deep without cavitation. |

'The VA-111 is launched from 533 mm (21 in) torpedo tubes at 50 kn (93 km/h; 58 mph).[3] A solid-fuel rocket accelerates it to cavitation speed, with a combined-cycle gas turbine in the nose creating the required gas bubble. Once accelerated, speed is maintained by an underwater ramjet fueled by hydroreactive metals using seawater as both reactant and the source of oxidizer; the torpedo travels at around 200 kn (370 km/h; 230 mph). Some reports indicate that the VA-111 possibly exceeds speeds of 250 kn (460 km/h; 290 mph), and that work on a 300 kn (560 km/h; 350 mph) version was underway.' |

(That's from Wiki so take it with a pinch of salt…) |

How many times more will the cost of countering Poseidons exceed their cost? First, let's look at the "wonder weapons" of past wars… How do you feel about the fact that the V-1 launches were entirely economically justified? Despite their near-zero combat effectiveness. After all, Britain was forced to invest enormous resources in combating these ersatz cruise missiles. A complete overhaul of the air-raid warning system, new high-speed aircraft, the best pilots deployed not over Germany, but behind the lines… Draw an analogy. The only difference is that the Poseidon is somewhat more effective than the V-1, and the potential enemy will be forced to defend a border several orders of magnitude longer. War is about money. Debits and credits. Pure accounting.
It's a weapon of deterrence. And there's also the nuclear-powered cruise missile "Burevestnik," which can attack from any direction… How much will it cost to protect against this threat? |

"my question what would be used to destroy it?" Well, in an ideal scenario, the hunter-killer sub shadowing the Russian sub would sink it before it could fire… ;-) |

Trump's "Golden Dome" suddenly springs to mind. How much will that cost? Now we need a Golden Water Filter…. |
