WW2 Night Bomber Formations

[Jetex Jim]

Night fighters were equipped with the "NaxosZ" unit which could home in on the "H2S Home Sweet Home" radar set used in Allied bombers.

By effectivly equipping every bomber with active beacons, (Monica and H2S) even aircraft too small to carry full AI sets - the 109 and 190, - which would otherwise have been restricted to a daytime role - were induced to participate in the night time battle.
