Depends on the threat from stand-off bombers.
In the Atlantic the threat was from Soviet bombers and it was considered cheaper to close the GIUK gaps with fighters and tankers based in Iceland, the UK and Norway. The USN carriers could then deal with any that got through.
Bigger threat was submarine launched missiles than bombers. The SHar was more a “hack the shad” (Bear D ) asset in the outer ASW defence ring than a counter to a stand-off bomber raid.
