In 1942, the Swedish Army Signal School (1942–1965) was established, and S 1 received an additional company in Stockholm, one in Skövde (S 1 Sk), and one in Kristianstad (S 1 K).

The jubilee was celebrated, among other things, with a large exhibition of signal equipment at the Swedish Army Museum.
