No, I called BS and his lack of any knowledge on "These aircraft are limited to 550 knots airspeed, Mach 1.2 and 5.5 G and carry internal weapons only. Of the internal weapons, the only useful weapon for CAS is the GBU-12 LGB. They don’t have AIM-9X, so they are at a disadvantage against almost any air threat unless the ROEs allow BVR engagement with radar only."
For the USMC to call IOC at 2B it means that it reaches the initial CONOPS requirement for the USMC. It doesn't reach the CONOPS of USAF or USN and the partners initial IOC requirements, that is block 3-3+
