Already the first posters misconceive. Guys, that's less armour than a light fighter. Also, to mention that, in ANY situation, a SNAC hit on a target smaller then a gunboat is pure dumb luck, even for the most skilled... Anyhow...
I personally like this idea, however, it could use some improvement. For instance;
Powercore: Make it a solid 30K Units. An extra 7000 would make too much a difference with the bomber guns.
Bot/Batt count: 20/65. I get the idea the shield is the main line of defense here, good idea. It'll make people think, and add new strategy to the whole thing, if this archetype is introduced.
Cargo space: Either make it /just enough/ for an armour upgrade, or less than such.
All the rest is fine. The profile could be up to debate, and an average agility can also be subject to change.
And as a note to other posters. don't just shoot it down because "ONOZ NO LIKE". Give it a test run. Why on earth do we have a Dev Team if we're just gonna shoot down new ideas? If you were any sort of smart, you'd be wanting to mounting pulse cannons on those two slots, and I can say from experience, unless you have luck on your side, you will always lose with those on a joust.
