[Atrocities]

Yes cloakable ships would be limited to a specific size limitiation. Think of them like submarines. You have your boomers, and your sub hunters/killers.

Boomers would be the largest, with each race having its own unique size limitations if the modder so desired to set it up that way.

I would hope that such weapons as Drones could be used as both a cruise missile weapon, and or a tactical or strategic interstellar weapon of mass destruction simular to our ICBM's.

Tactical is when something is used against a military asset, strategic is when it is used against a civilian target such as a major city or "planet."

Torpedo's would also be as the mainstay of this class of ship with them being semi powerful, fast, and as technology improves, semi to deadly accurate. Of course counter measure components can be researched and put on ships like Destoryers and or other vessels. (Destroyers having the best defense against Torps, while Carriers and Dreadnoughts have the worst.)

Would it be possible to make only missile weapons be able to destory ISBW (Inter Stellar Balistic Weapons) and cruise missiles?

The US and Russan Navy's love to use cruise missiles because they are so hard to kill.
