GBU-53/B StormBreaker is exactly a spice 250 equivalent that is already in game, so why dont gaijin give US the StormBreaker already? US CAS is borderline trash at top tier and StormBreaker would be a much-needed addition and should have been here a long time ago.
Granted that it uses the same seeker as JAGM (milimeter-wave radar, infrared laser, and semi-active laser) so it would probably be added as an IR and Laser versions. Aircraft that can carry it are: F/A-18E/F Super Hornet, F-15E, F-35(not in game), F-16C/D.
StormBreaker should have been added instead of the AGM-84H that doesnt even work properly
