I don't really know what this plane wants to be. It looks like a toned-down Thudernbolt , that sacrifices armour and firepower for a... -5 pts price drop? or maybe it is a re-shuffled, overpriced Avenger, I don't know

.
You should re-set this plane, because otherwise, it will be just a weird Thunderbolt/Avenger mutant. Replace the autocannons with multilasers (or heavy bolters), options for tactical bombs, missile launchers and stuff like that and maybe even the Supersonic
USR.
Also, the "Joint" in Joint Strike Fighter really refers to corporate cooperation. But it is OK I guess, as the Thunder could be the product of a group of Hive World arms manufacturers.
