It's optimized for low, slow, short-field, loiter, and good gas mileage like the A-10, T-6A, Super Tucano, and most drones. I wonder about unimproved fields though with the inlets so low. It is possible to place rock screens on the front of them but they still ingest a lot of crap.

Take a look at the air louvers on top of the main inlets on a MiG-29. Same idea.

Never noticed those... interesting. Wikipedia on MiG-29:

The engines are fed through wedge-type intakes fitted under the leading-edge extensions (LERXs), which have variable ramps to allow high-Mach speeds. As an adaptation to rough-field operations, the main air inlet can be closed completely and alter using the auxiliary air inlet on the upper fuselage for takeoff, landing and low-altitude flying, preventing ingestion of ground debris. Thereby the engines receive air through louvers on the LERXs which open automatically when intakes are closed...

The A-37 used retractable inlet screens to prevent FOD. You could feel a substantial increase in acceleration when they stowed away after takeoff.

Here's some shots from the net. Apparently it was just a flippable screen run off the LG hydraulics.

Yes, like a small drawbridge that rotated down 270 degrees to stow.
Ground FOD wasn't the only hazard -- notice how close the inlet is to the cockpit. With the canopy open, any item that blew outside would go right into the engine.

A friend of mine, who flew A-37s in Vietnam, was a consultant on this program.

If the Air Staff succeeds in killing the A-10 (which I think is a mistake), I hope they replace it with something like this. The Hawg is awesome for CAS, but is limited by hot/high performance in Afghanistan.

A high-aspect wing like this could solve several problems:

1. Takeoff with full armament

2. Loiter time

3. Operating cost

4. Ability to engage close-in fights due to slower final speed

Looks very similar in many ways to this....

The Hog does fine in Afghanistan. I think the problem AF leadership has with the A-10 is it's interoperability with fifth-gen fighters and the support it requires to operate in contested theaters. It's being sacrificed on the F-35 alter, but my hunch is that when the Army screams the AF is providing inadequate CAS capability, a fifth-gen (or sixth?) dedicated CAS airplane will be added to the fleet, regardless of whether the AF wants it or not.

How does the saying go? History repeats itself every 30 years? Or is it 50? Looked it up... it's 100. Hope it doesn't take that long to get a true A-10 replacement.

Why does it have a cockpit?
