Robotsystem 15 - RBS-15 Sweden Cruise Missile

The RBS-15 (Robotsystem 15) is a long-range fire-and-forget surface-to-surface and air-to-surface, anti-ship missile. The later version Mk. III has the ability to attack land targets as well. The missile was developed by the Swedish company Saab Bofors Dynamics.

Development of the RBS-15 began in the late 1970s under the name KSA. The first weapon contract was signed in 1979, at the last minute the Swedish government had opted not to buy the Harpoon anti ship missile and instead develop an indigenous design. The development took six years, and the ship version RBS-15 Mk. I was introduced.

The missile had been ordered in 1984 by the Swedish Navy to develop a coastal defense version of the RBS-15F. The missile was taken into Swedish Navy service as the Rb 15 by the Swedish Navy and became operational in 1985. The Swedish Air Force received their missiles a couple of years later. The Mk. I was produced from 1985 to 1990.

Work on a further developed version, the RBS-15 Mk. II, was initiated in the early 1980s. But it took until 1994, before a development contract was signed for the upgraded anti-ship missile. The Mk. 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. The Mk. II has been produced since 1998.

The development of the RBS-15 Mk. III began in the mid-1990s. Emphasis was put on increased range (due to larger fuel capacity and new fuel the range has been increased to some 200 km), improved accuracy (integrated GPS) and selectable priority targeting, which improved the weapon system's flexibility. The Mk. III missile will also be produced by Diehl BGT Defence of Germany for the new class of German stealth corvettes, and is likely to be later used on other German Navy vessels as well. Finnish truck maker Sisu produces missile launch trucks for RBS-15. The Mk. III has been in production since 2004.

RBS-15 Development phase

The RBS-15 missile was developed from the RB 04 missile that was used by the Swedish air force. 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 HMS Piteå from 1983 and became operational with the Swedish navy in 1985. The Västergötland class submarines were projected to have 4 vertical missile launch tubes for RBS-15 missiles in an extended hull but this was canceled due to budget constraints and it didn't fit the way Swedish submarines operated.

Robotsystem 15 Versions

Powered by a French Microturbo TRI-60 engine, with a thrust of 3.73 kN (380 khp/830 lbf). Range 70+ km

RBS-15F

An Mk. I adapted for air launch. Entered service in 1989.

RBS-15 Mk. II

Range 70+ km. Designed to be launched from a number of different platforms, such as land-based launchers, aircraft, and ships.

RBS-15SF

Mk. II version for Finland. Local designation MTO 85 (Meritorjuntaohjus 1985)

RBS-15 Mk. III

Range 200 km, with land attack capability. There is only a ship launched version. Production started in 2004. New Oval launch tubes instead of the old box type.

RBS-15SF-3

Both new Mk. IIIs and upgraded Mk. IIs, which have been upgraded to Mk. III standard. Finnish designation MTO 85M

RBS-15 Mk. IV

Currently being developed. Incorporates dual seekers, has a longer range and new missile link system. The radar signature has been reduced and its warhead can be changed depending on the mission. Future upgrades may include concept optimization for sea or land targets. The range of the Mk. IV would have to be significantly larger than others versions, over 1 000 km.
