Why Moskva might never detect an F-35 attack

Would Moskva know an F-35 attack was coming?

Probably not; the aircraft need not approach close enough to be heard, and successive attacks could accumulate damage.

An F-35 need not approach closely or fly supersonically enough to give Moskva useful acoustic warning. Stealth and standoff tactics could keep the aircraft undetected until weapons arrived. The opening bombs would damage exposed systems and weaken the ship even if they were not ideal armour penetrators. Later attacks could then exploit the cumulative effects rather than repeat the same engagement against an intact cruiser.
