You think me insulting, however I find your assertion that warships are easy targets insulting to their well trained crews.
How entertaining that on one thread we have hysteria because the Russians have installed S400 in Syria and somehow this owns and dominates everything out to hundreds of miles despite the obvious vulnerabilities of a ground based missile system, yet here you would have me believe that you can walk up to a modern warship with your general purpose bomber and plink it at will after defeating it's defences.
I notice, incidentally that you have chosen to attack the T23, an ASW frigate rather than a T45 which would obviously accompany the T23 into any area with an air threat.
That is a bit like me specifying that you are only allowed to attack in a Sentinel.
Good luck with bombing a T45 from above.
Yes, you can swamp any defence system. That has been true since the beginning of time.
The cost can be prohibitive though.
