Not really the City can just fly back to Pegasus I imagine, and with this new 'Wormhole Drive' the trip would be very fast and i imagine they could make a couple trips back and forth if need be. From a tactical standpoint i imagine that these would have to take place first before they go back:
- City gets repaired
- The ships get repaired and the new Hammond ship is launched giving them 5 battle cruisers, possibly leaving 2 near earth at all times.
