let’s not start this garbage againIf the Air Farce hates it so much
What with?Considering the cost of new wings, why not install newer engines too?
Setting aside the “popular zeitgeist”, pseudo intellectual beard, glasses, hand gesturing and funny accent, buying into his vehicle kill and attrition facts seem fraught, as the A-10 has always faced cultural bias. Pro f-35 commentators pick their facts. Every tank hit by a 30mm in the frontal glacis will also be likely hit elsewhere on the vehicle thus disabling the vehicle, for instance. Comparing a bomb’s damage to an autocannon rd’s destructive power is riduleous on its face.
The RR AE 3007 turbofan weighs in the circa 1600lb range, is used by the US military for a number of drones and aircraft and the late ceramic enhanced bigger fan models can develop between 10 to 12,000lb thrust,What with?
The USAF doesn't like the TF34 engine because it's unique so they also have to pay for 100% of the maintenance training and spare parts. And all of that gets wrapped up into the A-10 specific part of the operational budget.
Fair enough, nobody likes that.
But what engine would you use to replace it? You cannot use an engine too much heavier due to weight and balance issues, it needs to be within a couple hundred lbs. You also need to use a turbofan that is in current use with the US military, to take away that complaint from the USAF. Ideally more than just the USAF, so that they can share the cost of the schools with another service.
A TF34 weighs 1500lbs. A CFM56-7B as used in the P8 Poseidon weighs almost 5400lbs, way too heavy. The RR BR700 as used in the B52 reengining weighs 3600lbs.
What engine in use with the US military weighs less than 1700lbs and generates more than 9500lbs thrust?
TF34 is part of the CF34 family of engines. GE has proposed a number of upgrades over the years. TF34s in the A-10 might be unique to the US military once the S-3 retired, but the engines in it's family are widely used commercially.What with?

That's just thrashing about for justifications to get rid of a plane they've never wanted. They have aircraft with single digit inventory numbers that they have to support and they don't complain about that.Right.
But unless there's other engines in the DOD inventory that use that engine, the USAF will whine about having to support the entire cost of the engines themselves, and use that as an excuse to cut the A-10s (or a plane intended to replace the A-10).
Right, but eliminating those items the USAF can complain about will force them to say the quiet part out loud, that they do not want to support the US Army. And then you can fire Generals until the message is received that Everyone Works Together.That's just thrashing about for justifications to get rid of a plane they've never wanted.
Usually because those are supporting Stratcom or the POTUS. VC25s are a prestige thing. It doesn't matter how much those cost, you must have them. FFS, even Mexico has a Presidential aircraft, in the late 1990s it was a 757 and they otherwise had no money then.They have aircraft with single digit inventory numbers that they have to support and they don't complain about that.
