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.

Tests were carried out on Plejad class FACs with a single bow-mounted RB 08 in the late 1960s, but they came to nothing.

Saab's next attempt at anti-ship missiles to equip the Norrköping class FACs of the Swedish navy was in 1978 under the project name "RB 04 Turbo", a development of the air force RB 04E missile with a turbofan engine, changed wing configuration and start rockets to take off from land.

[3] The first weapon contract was signed in 1979; at the last minute the Swedish government did not buy the Harpoon anti-ship missile, opting for an indigenous design.

The Swedish Navy ordered the missile in 1984 to develop a coastal defense version of the RBS 15F.

II has the same range (70+ km), but the mid-course and terminal guidance system, as well as the radar and IR signature were upgraded.

In March 2017 Saab received an order for a new generation anti-ship missile to replace the RBS 15, valued at 3.2 billion SEK.

IV Gungnir can be fired from a truck, making it capable of launching from air, sea, or land.

The front of the missile was retained, including the warhead, but the rear received new wings and a turbofan engine replaced the rocket previously used.

The RBS 15 underwent trials on the missile FAC HSwMS Piteå from 1983 and became operational with the Swedish Navy in 1985.

It has the ability to knock out a wide range of sea and land targets, all-weather capability and a modular design that allows for future upgrades.

The missiles are to receive upgrades to increase their range to about 90–100 km as well as to improve their guidance, precision and survivability against jamming.

Bulgaria may also be arming its Coastal Artillery with RBS 15 Mk.III, but it has competition from the Naval Strike Missile and the Exocet[33][34][35] Some RBS 15s were delivered during the late 1980s for the new Yugoslavian Navy FACs to replace existing Russian-built missiles, but the project was never finalized due to the Croatian War of Independence.
