That's the trouble with a technological arms race; you end up with a lot of kit, and you can't ever discount the old "junk" in case the other side realises you've stopped fitting it.
There were some long lived systems in WWII. Gee was compromised by over enthusiastic trials by the RAF over Germany with an early set, which was lost and fell into German hands. RV Jones invented a system called Jay, in the hope of throwing them off the scent. I understand from Jones' book that once the Germans realised they'd been had, that Jay was a spoof and that Gee was the real deal, they completely ignored Jay for the remainder and it served as a useful homing aid.
