And what do you think Marine TACAIR should be doing? And against what threat country? And on what day of the war?
I suppose that's the real question. Right now, it appears that Marine TACAIR community, wants to be doing all of the things, against all of the threats and enemies, across the entire spectrum, on every day of the war, with pretty much the same airplane. But with only a handful of squadrons and people, and even less money.
I also think it's a mistake for the USMC to buy MQ-9s. It's a lot more than a light attack airplane, and it's capabilities go well beyond the scope of the 6 functions of Marine Aviation. Not to mention the cost associated with maintaining the GIANT tail that is required to fly them is probably beyond the Marine Corps' capability to pay. (I suppose you could sub out F-35 for MQ-9 and F/A for light attack here).
I suppose that's an interesting observation- the USMC is hanging their fixed-wing TACAIR plan on two very big, very expensive platforms that have Airforce and Navy capabilities inherent to them, that perhaps the Marine Corps doesn't need.
