Question: Is the hypersonic ballistic anti-ship missile option better than a subsonic cruise missile option?
Subsonic anti-ship cruise missiles are capable of hitting moving targets. A hypersonic ballistic missile could be used to hit ships docked in a port defeating shore-based anti-ballistic missile systems.
The most recent examples of large warships being sunk or damaged by anti-ship missiles have been through the use of cruise missiles.
The
R-360 Neptune missile used by Ukraine against the Russian Black sea fleet has been successful sinking at least two Russian Navy warships; the guided missile cruiser
Moskva and the salvage ship
Kommuna.
On 23 August 2023 a land attack variant of the Neptune missile was used to destroy a S-400 missile system radar, deployed on Cape Tarkhanut in Crimea since 2016.
The R-360L extended range variant used for land attack has a range of 1000 km carrying a 260 kilogram warhead.
