Hmmm, a secret airbase in the middle of the ocean !
don't the call that a CV?
actually this is a good idea.
but i don't think GV's should be allowed to up from it right away. getting planes there would be reasonable because new planes can fly there. but how would you deliver/build a panzer very far behind enemy lines?
but if the base was built say within a sector and a half or so of a friendly base then you could run gv supplies to it or over land a jeep to create a road (spawn route) to connect the new base via spawn to the already existing base. the vehicles could then spawn on the base. this would also allow vehicles to spawn in with supplies to continue the construction of the base.
when the base is first built then you could consider the base to be soft built, just a runway and enough tent as hangers to support a forward base. after this then the base could be converted into a hard base, solid hangers gunpits gv hangers ect, by players continuing to bring supplies to the base.
if the base defences are defeated (i have no idea how) before it is a full base then it is destroyed not captured.
eventually, if the base could be held long enough that is, and the required amount of supplies are delivered to it, then it could be converted into a full base.
the problem of building a town near it or how to capture it i leave up to the rest of the brainiacs to figure out.
