great comment. Agreed, however I'd be skeptical of surrogates when simply devloping a LRAAM (like the phoenix) that could both be used by the '21 and in small quantities on fighters might be more cost effective. Obviously, missiles would need enough range to allow the raider to fire and escape from long ranges, especially as once it fires a missile, it'll light up on most radars.
On that note, I'm curious about how the bomb bays on the raider have been optimized, considering that no matter how stealthy it is on the approach, it's going to be visible as munitions are released.
