SH as a launch platform even with network cueing cant replicate that engagement geometry or continuous fire control quality tracking that a ship based system does.
It doesn't and doesn't need to, its a launch platform, it doesn't guide the missile the Ship's own radar does, AWACS does.
how does fighter based AIM-174B handle a maneuvering hypersonic glide vehicle at mach 10 + with an unpredictable trajectory ??
Don't know about HGV, but An air launched SM6 is as capable as a ground/Ship launched ones as far as missile's own capabilities go in intercepting SRBM's & MRBM's
But in intercepting SRBM's & MRBM's , the SM6 use the method of terminal interception i.e. intercepting the incoming missile during its terminal dive phase, but it has its own problems like the incoming missile needs to be intercepted quite close to the ship/launch platform itself
For SM-6 , In a terminal engagement, the interception typically happens within 30 to 70 km (approx. 16–38 nautical miles) horizontally from the ship, at an altitude of 20km or less.
Ship launched SM6 has an max altitude of 34 km official, A2A version launched by superhornet( flying at 10-15km altitude) should reach even higher, 40+km altitude.
While the ship's own radars on US navy arlieghburke destroyers, especially latest ones, are capable of tracking incoming SRBMs & MRBM's from hundreds of kms away, at higher altitudes and providing long range firing track.
Using superhornet as a launch platform will greatly extend the range and altitude at which SM6 can intercept incoming SRBM's & MRBM's, allowing another extended layer of ballistic defence that intercepts incoming SRBM's & MRBM's in their descent phase( altitudes of 30-40km) way before terminal phase begins.
Along with that, it also extend the defense bubble against bombers, AWACS, subsonic or supersonic cruise missiles.
SM-6 can also be used in anti-ship role.
