I can't believe I need to point this out, but I will.The Ukrainian Neptune missile isn't less capable than most NATO anti shipping missiles. At least on paper. The best NATO anti ship missile is probably the Norwegian Naval Strike Missile. And I did hear rumors of possibly sending it to Ukraine. The Brimstone the UK was supposed to send is really short range and not really in same class of weapon.
If Ukraine had Neptune missiles, why has it taken this long to use them? Why didn't they use them when Russian ships were sat outside Odessa, or docked in Ukrainian ports? Clearly something has changed, and it's not the Ukrainians suddenly remembering they have Neptune missiles.
