I was wondering if anyone might want to take a crack at designing a completely different planetary defense submersible platform. The Wyrm is interesting, but it leaves much to be desired in other aspects. This platform would mass about 25,000 tons and would be powered by a fission power plant instead of a fusion plant. The platform's principle anti-spacecraft weapons would be four AR-10
's and four NL-55's. For short range defense, the platform would rely on batteries of large lasers and PPC's along with long and short range torpedo batteries (SRM-4 & LRM-20 equivalents). To support group forces with artillery fire, the platform would have at least one Long Tom and one Arrow IV system. Point defenses would be handled by a combination of AMS and small pulse lasers.
The platform would be heavily armored and would principally use 2750 Star League level technology, so ER range versions of large lasers and PPC's could be used. Pulse lasers can also be used to supplement anti-fighter batteries. The platform would have the capability to support large craft like the Manta and Neptune as well.
Have fun....
