The L159T being negotiated for were in storage and parts had to be resecured. The avionics and engines were probably sold off previously as the Czechs have been cash poor trying to find sales of anything aerospace. The new generation L-39 looks easier to sell. Everybody in L-159’s market wants to build their own because so much is available on the open markets.

The tails of Lockheed’s F-117A, Sukhoi’s T-50, and Shenyang’s J-20 are very interesting. All moving and at steep angles. Not your typical rudders or tail plane-elevators. Useful for pitch and roll control, plus at the same time augments the yaw control.

1. I’m not sure the L159T was a turnkey solution, so it probably had too much lead time to introduction.
2. Any specifics here?
3. No number of Su-25’s is going to secure their airspace
4. T-50IQ should help train F-16IQ pilots immediately, but otherwise is not that much tactical help.
5. Pretty useless IMHO.
6. I believe they this made the decision mid-summer of 2014
7. With drop in oil prices this has to hurt Russia.

Feathering or not, auto-rotating props are a load of drag. They never solved this issue.

True, but F-105 yearly production probably exceeded Buccaneer total production. :dev2:

You don’t mess with the recipe in mid-production.

J75 was a pretty powerful engine and like I was getting at, there was no suitable turbofan engine to replace the J75. Probably not a single one until the F100, which had its own teething problems. F-16A was the single F100 warplane and built for hard manuevers. F-105 failed as a demonstrator because it just wasn’t stressed for hard manuevers. Don’t underestimate the F-105 in dry thrust, because wet or dry the thing had a speed advantage over the interceptors it faced. Look down & shoot down radars negated this advantage.

And they probably matched its AoA for level flight. Planes in that era cruised with a slight pitch up. This was before leading edge slat extension.

All somewhat irrelevant for the time period of Vietnam war era. The RN and RAF didn’t enjoy the the same inflight refueling capability that the F-105 had available to it.

OT- Not too any USAF aircraft enjoyed two ways to refuel like F-105D. That was an advantage, too.
