the Me410 "Schnellkämpfer" had a Stuvi , but no bombsight for levelbombing.
they researched to equip the 410 with a Lotfe7D , but there was no way to make it practical and usefull.
said, the Kampfflieger had to use it because it was there and the "bosses" made the decission to build it instead, as example, the Ju88S.
the production of the Ju88 was actually reduced to build more Me410
two man crew, two engines are a waste of resoucres to bring one SC500 to England.............................IMHO !
two SC500 reduced speed and range because of the gap in the bombdoors, and two SD500(that fitted in the bombroom because of smaller shape) was not realy the correct weapon.............
and anyway, one cant compare the german bomberforce of 1943+ with the masses of strategic bombers at day and night and the tactical bombers at day the allied used. that was way above the possibilites the germans had !
