I was under the impression that the E-Wing lacked the intestinal fortitude to be a fleet bomber - certainly, the hull seems to dainty, narrow, and focused on speed for it to back a lot of heavy weaponry. I do like the idea that the X-Wing has longer range and better endurance - it syncs up with the Army (of all things) using the E-Wing in Mercy Kill. I wonder if the rise of the XJ is similar to the current switch from the abortive F-22 transition to the F-35 in the American military. The F-22 and the E-Wing are both fine machines, but what if the E-Wing was also to expensive and finicky to the needs of the service (and the budget-makers) at the time. In the Senate was convinced that a re-tooled X-Wing spaceframe would be a cheaper and effective answer to the New Republics needs, maybe the ordered funding to be funnelled towards the XJ project. Incom, in typical Incom fashion, then proceeds to totally exceed expectations and turns out a highly capable modernized version of the X-Wing, a craft that is different enough that it is usually called by it's variant designation (XJ) rather than an X-Wing by military professionals.
