action groups. 1: toggles all vtol engines.

It is big enough to count as a base, I think.
This is a MASSIVE SHIP, that can fly at 135 m/s. it is slow, but can carry many kerbals and has room for science under the bottom level.
Total weight:120.8 tons
That is 241,600 pounds.
or in metric. 109,587 kilos
It will lag to have more than one loaded, unless you have a good computer.
If you are going to use this with BD's armory, I would suggest putting on many weapons. The total lifting power is so high that you could add over 20 tons of cargo to it and still lift as a vtol. If you are going to add more than 20 tons of cargo, I would suggest using whiplash engines instead of wheaslies, because you need to be at full throttle to lift even a tiny bit with 20+ tons.
I wouldn't use Destruction FX when battling with these, as there are many parts. it already lags my computer.
