After the XF-305 B, RoCh Aviation wanted to make a similar jet, but that could fulfill differents missions, as air to ground actions ; that's why they created the XF-312. This aircraft is specialised in air to ground attacks, as it carries 4 bombs Boom-50, and 2 nuclear missiles "Cleaver". In addition to these, it is also equiped with 4 air to air missiles "Guardian" ; but an updated versions of these, that can target aircraft further away. AG-1 for carrier hook ; AG-2 + Brakes to reverse the engines (don't push too hard on the brakes, otherwise you will go backwards at around 90 mph) ; AG-3 to deploy landing chute ; AG-4 to drop all 4 bombs. Enjoy !ùù
