I recently also read that the Germans failed to design their first EM-warning sets to detect precisely the centimeter-wavelengths which the British radars would use to tag U-boats at night, because calculations had shown that such radars were not the most efficient - so what kind of worthy opponent would ever develop one...??! That intellectually-elitist and STUPID attitude cost them a lot of U-boats, with all hands lost.
This business of being too high-tech - "too smart" for one's own good - also reminds me of the early '60s US DOD's "Missileer" concept: that the pursuit/(dog-)fighting aircraft would be completely replaced, over land and sea, by the radar-vectored, all-missile-slinging interceptor. Leaving quite aside the inconvenience that contemporary medium/long-range AAMs - namley, the Sparrow - apparently sucked big-time, the policy to deprive front-line jets of ALL guns produced (more than once, IIRC) the absolutely ridiculous situation of a hot pilot getting the drop within a hundred yards of his adversary's tail and not being able to DO ANYTHING to him! (Except maybe suicidally jam his nose up the other guy's a**-pipe. )
That was one of the stupidest "bureaucratic/egghead" episodes in all of American military history - second only, of course, to the pre-WWII US Navy's refusal to test "expensive" torpedoes, to see if they actually even worked right!
