I think that either CIG should enlarge the BMM to be large enough for a hangar large enough to store a Defender or to announce a Banu capital class carrier ship eventually.
As for jump portals, I think that Aegis should create a ship that portions of it expand out to create within it's circumference an end point of a man made jump gate. Think of the jump gates from Babylon V, but able to be condensed & transported by a mid-size ship. All you do is have a pair of them, 1 goes to the desired system, they both expand & then link up to form a massive jump gate for the largest ships to pass through so that a fleet can operate in almost any system.
