Within range, yes! Doing serious damage, I'd have to say not so much. If you think about it there is a trade off as the Germans found out in WWI & WWII. In both wars they attempted very long range shelling of Allied cities. In WWI they tried shelling Paris from 75 miles away. The effect was disappointingly small as the bursting charge has to get smaller the further you try to throw it.
"a rocket boosted shell" will travel further than a shell with out the rocket assist. The down side is in order to shoot further you will have to reduce the bursting charge to account for the weight of the rocket propellant! Much like the German Paris gun results, the further you shoot, the less effective the shell becomes. Big bang requires a bigger bursting charge...

PS "In the 80's the Navy had developed a rocket boosted shell" I seem to remember the "SubRock" was used in the mid 70's with a range of 90 miles or so. Those could have been tests of a preliminary prototype.
PPS Prior to the development of GPS technology, shooting over the horizon would be problematical without a spotter. The ballistic tables for the German Paris gun included corrections for the Earth's rotation while the shell was in flight!
Many thanks for the information.

The crafty Germans also made allowance for bore wear and enlargement after each shot.
