Where is the source for that? It wasn't on the link? TRG-300 has 90 km maximum range listed by Roketsan, if the range expansion follows the same pattern as UAV-230 and 122, it should have just about 200 km, not 500.
300mm rocket that we produced with help from china since 2000 have 120 km range with 105 kg warhead , and 90km with 180 kg warhed .
So depends on variants and warhead weight .
This air lunched is bigger 370mm , 5 meter , 900kg as opposed to 585kg and 500+ km accroding to rocketsan .
F16 can easily keep it under wing; thats why i was sceptical about Bora air launched and i was right .
If we take eurofighter perhaps we can fire Kinzhal type missile from it .
