Wasnt this Germany had no effective nightfighters nonsense also from him ?
This was made up by me. For a night time fighter to be effective it had to have a combination of the following:
1) Effective Radar (or rather the space to mount an effective high power radar).
2) Stable flight pattern during manouvre
3) Long endurance
4) Heavy armament
The principal German night fighters in the time where it mattered were the BF110 and the Ju88. Neither were designed for aricraft engagement and their armament was relatively clumsy - that is, their design characteristics meant that they couldn't act as an effective gun platform. What is worse, is that the retrofitting of armament greatly diminished some of the design features making them less aerodynamic. They were sluggish and difficult to control with the armament necessary to attack enemy aircraft and when more powerful/nimble aircraft like to mosquito were the opposition ... well they got 'bitten'.
The other major flaw was the German radar. This was based on 2 issues. The first was that their systems were not as effective as allied systems using the Cavity Magnetron technology. This meant that the allies had higher power (more range) and higher frequency (smaller electronics, smaller antennas, better resolution and again likely more range). It was like trying to fight with 'foggy' lenses. Secondly, because of allied countermeasures were highly effective and due to the operational analysis branch, were able to assess the performance of things like their ECM by the effectiveness of their missions. Intelligence on the German radars also helped.
Germany also suffered by simply not having enough. In 1942 when Britain started to launch bombing raids with over a thousand aircraft, the entire strength of the Luftwaffe night fighter corps was around 200 ... for the whole of Germany.
So, if the poor state of Germany' night really is 'nonsense', I would like to understand why you think that is the case?
