I’m not fully convinced though the P-15/HY-1/Silkworm likely stands the best chance of any ASHM due to the warhead weight.
A 500kg hollow charge warhead means the explosion firstly is directed and therefore is likely not enough to get through 12-18 inches of battleship armour and pure HE effect wouldn’t kill the ship as its not below the waterline, by the magazines and won’t be impacting the weaker deck armour as it will be coming from the horizontal plane.
For reference the TU-2’s FAB 1000kg bomb with ~450kg of TNT filler (keeping in mind P-15 afaik doesn’t use a TNT filler so explosive equivalent is likely closer to this) has landed next to me and has not killed me in HMS Hood, further ships only improve anti torpedo protection and thereby underwater protection, belt impacts are virtually not even considered to be threats even from torpedo’s with warheads similar to those on P-15.
Which is the word to refer to what would have been called Dreadnoughts in the 1910’s.
Batlleships, Fast Battleships and Battlecruisers that have 380mm of armour rather than 38mm. And displace 40,000+ tonnes rather than 7,000.
After WW2 armour essentially dissapeared in exchange for compartmentalisation and firefighting and speed. Ironically, some naval historians argue there could be a shift back towards heavier armouring of critical areas now ASHM’s are considered to be un-interceptable.
Not entirely true. The Brit community gave them a massive amount of criticms about how they modeled the Challenger 2. So they nerfed the Challenger 2 and 3
