miss. Best results were usually attained when firing in salvos against large ground targets. Almost every Soviet military aircraft of World War II was known to carry RS-82 and RS-132, often using field-made launchers. Some Ilyushin Il-2 were field-modified to carry up to 24 rockets although the added drag and the weight made this arrangement impractical. A total 12 million missiles of the RS-type were used by Soviet forces during World War II. RS-derived M-8 and M-13 rockets were used by the famous Katyusha rocket artillery.
