Yeah, Oz, I had PM'ed Wyrmshadow several times myself, asking for this, it makes a much needed upgrade to the Battleship in the Modern era. Glad he finally got around to it.
The run sound is actually the same as the AEGIS cruiser, I tried tweaking this about but wasn't satisfied, so left it as is in the zip - all the other sounds are custom though. The rocket attacks fit well with what this is supposed to do, and seem to work ok as they are in the INI file, though I wonder if there is a way/tutorial to make new AMB files for custom units around somewhere.
Anyway, I think these sounds make the Arsenal Ship into a fairly complete and well rounded unit. Now, if I can only get Wyrmshadow to make me a Sealift Ship...
