Actually, no. The Shah was always interested in the F-14 because of the Phoenix AAM, and it was McAir that insisted on the air show at Andrews AFB during a state visit by the Shah. The Grumman demo team put on a show, and the rest was history.
Well seeing as I did a UK one:
Luftwaffe
Do19 - as production alternative to Do17 (which means little or no Fw-200).
Me-110 - as a light-bomber alternative to the Do17
Fw-187 - as 'heavy' fighter alternative to Me-110
Then in the aftermarth of the French defeat
Bre-690 - replaces the Hs-123 for Close-Support
To be honest, I am not familiar with the Bre-690, but it one wants to consider the adoption of foreign types instead of German designs, why not consider ordering or licence-building the Italian Piaggio P.108 - a modern four engined heavy bomber that could have been in Luftwaffe service by late 1941/1942. Far more capable than the Fw 200 and far more reliable than the He 177.
The P.108 or CANT Z.1014 would need much better engines though, like BMW 801s or Jumo 211s to match the performance of the Junkers Ju 290.
How about the Dornier Do 19, Ural Bomber. Would a fleet of these been better for the Luftwaffe in the night Blitz on Britain in 1940?
Really?
In a check of Wikipedia (yes, I know...) the P.108 and Ju 290 look fairly equivalent. Roughly same maximum speed and offensive load capability, with the Ju-290 having a substantially longer range while the P-108 having a much higher operational ceiling. The P.108 was available in 1941/42 and was designed as a bomber. The only Ju 290 that was ever produced with any offensive load capability (the Ju 290 A-7) wasn't produced until 1944. If the Germans wanted and needed a reliable heavy bomber, the P.108 is the only likely option that could have affected the war in any meaningful way, with or without better engines.
If The Do 19 had been adopted for Luftwaffe service then I would suspect that engine upgrades etc would have neen applied by 1939, Also with a succesful 4 engined heavey what else my the fertile German areonaurucal minds produced? IMHO the Death of Major-General Wever in 1936 was a very fortuitous event for the Allies.
The Do 19 was not a technological alternative to the Do-17, so if Dornier was instructed to develop the Do 19 as a production heavy bomber instead of the fast light/medium bomber Do 17, the utlimate result might have been to deprive the Germans of a very versatile design that, it its later Do 17 and Do 217 developments functioned well in a variety of bombing, maritime attack, recon, and heavy fighter roles, in exchange for a heavy bomber that was representative of the same technological era that produced the Armstrong-Whitworth Whitely and would have been obsolescent by 1941-42. True, the Do 19 might have been a better airframe for adapting as a maritime recon-bomber than the Fw 200, but even that is questionable (plus, see the P.108 below).
Regarding the Bf 110 (and its near cousin the Bf 162), it seems to me that it would more likely have been considered an alternative to the Ju 88 than the Do 17. Given the fact that the Ju 88 and its sucessors was arguably the best overall warplanes employed by the Third Reich, this would be a big mistake.
To be honest, I am not familiar with the Bre-690, but it one wants to consider the adoption of foreign types instead of German designs, why not consider ordering or licence-building the Italian Piaggio P.108 - a modern four engined heavy bomber that could have been in Luftwaffe service by late 1941/1942.

Abrgd.
What about the RAAF actually getting the Avon engine in their Mirages. After the Mirages were built for the Avon the RAAF decided just to go for the Atar 9C, meaning that all the maintenance access panels and doors were in the wrong places.
