An Integrated air defense system makes sense for the British on their
island. For the landlocked Germans, who had no channel, a philosophy of
avoiding a war of attrition and winning the frist battles so as to avoid
fighting on German soil prevailed. Very little was devoted to defense it
was thought best to devote it to attack and support of the Army and this
probably starved the development of such systems eg IFF.

The German IFF systems (FuG 25 and FuG 25a were the aircraft
transponders) were actually pretty good. Their coding system was
extremely flexible, and it did not use a wide swept-band system like
the Allied Mk III IFF kludge. So technically, they were on the ball,
as far as IFF systems are concerned.
