Yes, I think you're right qraal. Although the Star Trek craft combined hub-cap with missiles; but they can be excused, as they also served as landing craft!

Which brings me to mentioning that I've recently finished watching the entire Star Trek Voyager series, which I think is brilliant. One could attack the program on the grounds that it isn't agonisingly realistic. But why be concerned over that? It's a visual delight, thoroughly absorbing as the central characters develop throughout the 26 episodes, and all-in-all excellent entertainment. This is the kind of space soap that I like. The end titles of the final episode were a sad sight.
