Seriously, SNEB is a short range LOS weapon whereas Martel was supposed to be BVR and theoretically, like the Trykon I mentioned, steerable around a river.
SNEB operational use sounds like Operation Certain Death. TV data link would be stuffed and the AR blind I suppose, damn those laws of physics.
I recall being told that a near miss to a ship with a 1000lb would be good enough as the compression wave would burst bulkheads. No idea if that is true though.
