The Swedish Navy earlier made the RB 08 anti-ship missiles with the Halland-class destroyers in the early 1960s. The main effect of Sweden's defence resolution of 1958 for the Swedish navy was restructuring into a lighter force consisting of fast attack craft (FAC) vessels and a halt to destroyer procurement. This posed a problem as the existing RB 08 missile required launch rails and a missile magazine in the destroyers, taking up space that was not there on smaller ships. Adding to the problems, each missile had to be individually prepared for launch and only two missiles could be on the launch rails at the same time. In comparison, the P-15 Termit (NATO codename Styx) missile used by the Soviet Union from the late 1950s (which was the expected adversary of RBS-15) stored the missiles in individual containers on deck which left the missiles immediately available for launch. Tests were carried out on Plejad class FACs with a single bow-mounted RB 08 in the late 1960s, but they came to nothing.
