|After watching the new Battlestar Galactica series I cruised by some fan websites. I saw a facetious comment that the landing bays of the Battlestar Galactica have giant signs on them saying 'attack here'. It went on to say that this major design defect should have been corrected from the original series design.
I smiled at first having thought the same thing for years but upon further thought believe the design to be both sound and innovative.
My take is that the design, with the landing bays being on struts away from the main hull, allows for the isolation of damage. Much like the engine pod design of the A-10.
Landing bays/decks are always going to be a prime target no matter where you put them. They will always be more vulnerable than the rest of the hull since they need to allow access for fighters to land. By isolating the landing bays from the rest of the ship (and each other) you provide greater protection for the main hull and the other landing bay. Better to have fuel and munitions kept away from the main hull. This also allows guns on the main hull to cover the landing bays and flight path of fighters on final approach.
