To permit a longer stand-off against a well armed platform with a modern air defence system
Such as what...? Aster..? Nope... HQ-9...? Nope.
The missile isn't designed to attack a "Well armed platform with a modern air defence system"... It just isn't capable.
There may be occasions when disabling fire rather than lethal fire may be more appropriate to command within the operational context or ROE. Why not provide a highly trained operator in the loop capable of making an informed decision.
That's the job of the command and not the job of the missile operator.
Do not give the missile operator the ability to make such decisions. His job is to fire the missile against the target he has been ordered to engage. Not to determine whether he fancies it or not.
