A speculative space-warship concept favors missiles and railguns

How would you build a space warship with current technology?

The proposal uses nuclear power, missiles with more fuel and nuclear warheads, and railguns if they can be made to work.

The proposed space warship would use nuclear power and missiles, with railguns if they could be made to work. Large missile bodies would leave room for more fuel and a nuclear warhead. Compact Western components are preferred to make better use of that volume. This is a speculative choice of technologies, with railgun development still an unresolved condition.
