Found a rule in TS:Under Pressure. Basically the rules you suggest, not those from VE, but with less severe modifiers, -1 per 2-25 yards, with the lower range near the coast and the higher range on the open ocean. Call it up to -20 or -25 for a sub at 500m in the deep ocean or near the bottom anywhere else - as the bottom depth and hence the maximum dive depth goes up, the water becomes murkier, too . A ladar with 500 miles nominal range should do the job if there is no stealth. TL9 countermeasures mean 5,000 miles is more like it ... that would be the set of a large starship or a specialized sub-hunter. _______________________________________________ GurpsNet-L mailing list <[email protected]> http://mail.sjgames.com/mailman/listinfo/gurpsnet-l
