Subsonic missiles are not true missiles.
Yes Supersonic speed makes it very difficult to detect and track ....
but New Turkish MILGEM-I class stealth Frigate will be armed with 64 x ESSM ( 50 km range and mach 4 speed ) to intercept BRAHMOS Supersonic Anti Ship Missile
the BRAHMOS will be detected at about 25-30 km from the Warship when it is in its sea-skimming terminal phase with supersonic speed at 1km/sec and Turkish MILGEM-I class stealth Frigate has about 25-30 seconds to react
We have 4 ESSM SAMs targeting each BRAHMOS Missile and the probability of interception is theoretically 100%

JAPAN has developed XASM-3 air launched Supersonic Anti Ship Missile ( mach 3 speed and 150km range )
and Turkish ATMACA and French-British PERSEUS Supersonic Anti Ship Missiles are on the way
