Unguided AA weapons were pretty popular in the WW2 era.
Germans built or designed a number of them some were already mentioned: at least four types of Kurzzeitsperre wire barrage rockets in calibres from 8,6 to 21 cm (made by Rh-B and Krupp), then Fliegerschreck, Fliegerfaust/Luftfaust, Foehn, Flakrakete 42, Feuerwerk, Maikaefer, Orkan against low to medium altitude targets, plus Taifun, Tornado, two types of Rheinkind, 10,5 cm Fla-Rakete against high altitude targets. And more. A whole Planet project was to develop more or less unguided AA rockets carrying subprojectiles.
In the USSR there was a wire barrage version of the later Katyusha rocket developed under designation RZS-132, already in 1930s. During the WW2 very few specially designed Katyusha rocket launchers (with regular rockets, though) were operationally tested, achieving one or two kills.
British Navy and AA defense used several variants of UP rockets, both wire barrage and HE (including optical proximity fuzes).
