How about just adding a different form of lock into the Target Lock rules? Could call it something like "Ordnance Lock"? Suppose any ship able to carry ordnance is allowed to acquire a lock on any ship in the play area and with such an "Ordnance Lock" is allowed to fire specifically declared "Long Range Ordnance" at the target up to range 5 with additional defense bonuses for the target at ranges 4 and 5?
Also this way the title card for ST-321 wouldn't lose its value do to the fact that it would still remain as the only non-ordnance carrying ship in the game that is able to acquire an original Target Lock on any ship in the play area.
I know such an addition to the rules would require some major play testing and would probably require the adjustment of point costs to some ships and upgrades. However, if FFG were to ever do a reboot on the game to fix wording and game quirks, it would be some good food for thought. I personally would like to see this happen as I have always felt that most ordnance is quite marginalized.
As far as the posts about the game being a "Dogfighting Game", I do believe that ordnance does play a pretty major roll in Dogfighting and in my opinion the value of ordnance is not fairly represented in this game. Plus lets not forget that FFG did decide to add Huge ships to this game, which are not Dogfighters, and do make tempting and easy to hit targets at long range for some kinds of ordnance.
That's my 2 cents.
