Pretty good analysis Rich, read the same thing on several defense sites since the word came down recently RE the A10. Funny stuff - don't you love it when a plan comes together.
Also, regarding the fratricide rates with the A10 - since it's down in the weeds, doing the lions share of the work when it comes to employing things that go boom, bang, and pow in close proximity to friendly troops, at a rate far higher than any other platform, isn't it obvious that it would have a higher rate of fratricide due to this fact?
Other aircraft and systems in recent conflicts have had notable fratricide rates as well. In fact, if you google the list of aircraft related fratricide incidents since 2001 in both major conflict zones, the A10 is really no more responsible than the F15, F16, AH64, and Harrier (both USMC and UK), in terms of numbers of incidents. Then when you take into account the typically much closer proximity the A10 has to friendly troops, the fact that air combat controllers can call in A10s closer than bomb equipped only aircraft, or a/c without a dedicated strafing gun like the Gau8 30mm - IMO it becomes pretty clear that the A10 crews are no worse than any other system out there, perhaps even better, again due to the frequency and proximity of their type of work to friendlies.
I personally think the USAF should have let the A10 go, and that if the Army was concerned enough about not having adequate CAS in future conflicts, THEY, as in the US Army, should be allowed to "take back" this sector of the air war game, and be able to provide its own systems for doing so - ie taking over the expense of the A10, and having Warrant officer pilot programs for it like the AH64, or created its own new aircraft/drone/whatever to do the same job. I always thought it made more sense for CAS and air combat that is completely ground related near the forward edge of the battle space, or in proximity to friendly ground troops, to be the Army's bailiwick anyhow, and since the AH64 is already doing that job, pairing it up with slower moving fixed wing stuff to supplement and complement it, with guys in Army uniforms, made more sense than having the AF or Navy do it.
