Getting pretty boring from a modelling perspective isn't it. How many new fighters - ah, one. How many paints needed - ah, two types of grey!
Marines have always done their own CAS, except when needing help from services. B-52's have also been used as CAS in Afghanistan - such is the flexibility of weapons like the JDAM. Munitions are getting smaller and more precise. The SDB is only 250Ib and future SDB's may have selectable yields less than this. With JTAC's controlling where the munition is to go, the "fighter pilot" these days is releasing a weapon that has been targeted by the resident JTAC on the ground. Point, click - BOOM! US and British Army Apaches have fired Hellfires into specific rooms in Afghanistan, leaving the others intact. Kind of amazing to see what has transpired over the last 70 years. From fleets of bombers required to take out a target in the past to now only a couple of fighters can potentially cripple a nation taking out it's ability to generate power, refine oil, communicate, you name it. It won't be long before truly autonomous un-manned fighters can do this.
An interesting point in that article is that all the recent CAS has been in relatively permissive environments. How all this plays out in a serious shooting war would be interesting wouldn't it. I'm fascinated in the technology. Way outside of my experience to comment on whether or not such technology will work or not. Kind of getting off topic a bit but related though, from all I have read from the "users" themselves (USAF. USMC, USN), all are blown away with the F-35 so far. One could argue they have to say this yes. Still, not being a expert or being part of the F-35 program, all I can go on is what is being released to the public. The F-35 ain't the prettiest bird around, but look at the A-10! As a tax payer, all I care about is that it does it's job - bloody better huh!
Sad all the truly cool aeroplanes are going going gone!
