For some background on the 210/410. I've done some reading on both models. Both were disappointments to the LW.
Production was canceled of the BF110 due to the anticipated arrival of the 210/410.
When they entered service the 110 as I recall was put back into production because of the failures of the 210/410.
Also, when long range escorts were put into service the 410 was pulled by the LW from Bomber interception.
IMHO both models failed because as in the past they wanted the 210/410 to be an all purpose aircraft.
They didn't do anything partculary well and were a chore to fly specially the 210. They just carried big guns.
We'd have been better off with the Beaufighter! Big guns and it flew fairly well in many aspects from fighter, night fighter
to delivering bombs,rockets, and torpedos. That was a successful multi use aircraft. It operated in all theaters for the
duration of the war. (I just had to get that in)
