All lot 20 hornets were delivered in 1998. It also doesn't matter since BRU-55/A is compatible with all hornet wing stations as you can plainly see.
I'm not arguing about the LITENING pod on the centreline because I don't know if they made any modifications to the electrical system on that station
I do know that BRU-55/A racks contain standard hardware and fully support GBU-12s. I also know that the NATOPS manual for the F/A-18C (that is up to date with Lot 20) has detailed information on the weight, drag and operational requirements for GBU-12s on dual racks.
Your point is that Marine hornets sometimes do things that Navy hornets don't do. Alright, would it suit you to have BRU-55/As with GBU-12s only available for DCS Hornets with Marine skins?
I think that's a bit silly frankly.
There's no reason for this capability to not be simulated.
I also have not seen an A-10C that I can verify is the same lot as the one simulated in DCS with suite 3 carrying AGM-65Ks. Does that mean it shouldn't be simulated?
I contend not.
