I remember seeing something about Buccs using SNEBs in the Norwegian Fjords where a Martel would have been unusable due to the proximity of land returns. Mainly intended against soviet amphibious forces. Although google does not back me up with any reference.
I would have thought rockets would have been accurate enough against ships- just a couple of hits would most likely put a frigate or destroyer out of the fight - tanks are far small and harder to see!
Rockets give you a little bit of stand off and certainly more chance of living than trying to do a lay down with 1000 Lbs!!
I remember Pucaras had SNEBS at Goose Green but never heard of any of their fast jets.
