With an 80-pound nuclear package, you can easily build a 16cm missile using the Spaceships rules. With this design, the missile only has 6.3 miles per second delta-V and 4G acceleration - with a larger missile I'd use something similar to the Menippe for propulsion, a mini mag-orion in a missile massing around ten tons, making it a very long-range, high-speed weapon.

EDIT: Oh, and remember that the missile pod itself masses a total 30 tons while the boat that carries it also masses 30 tons. The whole delivery platform masses 60 tons.
