So what, there is no point of reference. The other cubes weren't called "Strategic" or "Class 1" so these words are meaningless when comparing the cubes. Even if we assume, for example, that a higher "class" number means a weaker ship, it's still useless information because the other cubes could just as easily be "Class 15" as "Class 1". This is the line where the "class 4 tactical" was introduced: SEVEN: This is a class 4 tactical vessel, heavily armed. The central plexus is protected by multi-regenerative security grids. We'd be detected long before we could reach it. How can anyone look at this line and claim that it's describing a ship that's weaker than what we're used to?
