Limited to a ~20 mile range....
20 miles gets you on the beach plus 5 to 10 more inland,...
after that you got your own cannon cockers, treadheads and air power,....
and really, a 90 mm against modern AFVs and MBTs?!?!?!?
not so much,...
sad to say, those 16" hammers are no longer active either,....
then again, one can build a LOT of missiles and quite a few choppers for the annual OPTAR of an Iowa,...
ah well, onwards and on,...
