BAMSE SRSAM

Summary

The BAMSE SRSAM is a wheeled SAM system that is made up of an Eldenhet 23 BAMSE mounted on the back of a Super Stallion 8x8 truck which was made in collaboration between Saab and Ashok Leyland in 2014. It comes with six missiles and has a long-range, however, it has no search radar so all targets need to be detected manually. It would be very similar to the Lvrbv 701 currently located in the Swedish tech tree when it comes to playstyle, but it has upgrades in almost every regard, except for the addition of a search radar.

History

In the middle of the 1980s, Sweden required a new air defence system that was able to defeat small and fast targets from far away to protect strategically important locations such as ports and air bases which led to the start of the development of the Robotsystem 23 BAMSE. In 1999 it was decided to adopt the system, with a contract following in 2000 for Saab to produce the system for the Swedish military where it entered service in 2008. Later in 2014, Saab teamed up with Ashok Leyland for the Indian Army’s ground-based air defence programme, with them offering a variant of the Eldenhet 23 BAMSE system called BAMSE MCC mounted on the back of Ashok Leyland’s Super Stallion 8x8 truck, which came to be called the BAMSE SRSAM. This vehicle was also displayed at the Saab booth at DefExpo 2014 where a model version of it was put up on display. The Indian Army never ended up procuring the BAMSE SRSAM, but in 2016 a functional version of this vehicle was put up for display at the anniversary of the Swedish Air Force in Linköping where Saab demonstrated it.

Features

Hull

The main hull of the BAMSE SRSAM is the Super Stallion 8x8 made by the Indian company Ashok Leyland with the BAMSE MCC missile launcher made by Saab mounted on the rear. This is an 8x8 truck which was designed to give a high mobility in demanding environments. It has a crew of three with the driver sitting in the front of the truck, and both the gunner and commander sitting inside the crew compartment of the BAMSE MCC launcher. The truck has no protection whatsoever, but the crew compartment in the launcher is protected against fragmentation.

Armaments

The BAMSE SRSAM is outfitted with six Luftvärnsrobot 23 missiles mounted on the BAMSE MCC launcher. This launcher rotates around a central mast where the sensors are fitted. On both sides of the mast, there is a launcher holding three missiles each. These missiles have a range of 20 km, can shoot down targets 15 km in the air, and have a top speed of Mach 3. The missile consists of two stages with an initial booster accelerating the missile to a speed of 3000 km/h within a second, after which the smokeless main engine starts to propel the missile toward the target. Well at the target it has a proximity fuze and a backup contact fuze to detonate the pre-fragmented warhead within the missile. The Luftvärnsrobot 23 is guided by radar beam-riding where it rides the beam of the tracking radar fitted on the top of the mast. It has both ACLOS and SACLOS modes for firing. The mast needs to be deployed for the missiles to be fired, and without it raised, the gunner’s sight wont is available.

FCS

For fire control, it has an eight-metre-tall foldable mast that extends from the centre of the BAMSE MCC launcher. At the top of the mast, there is the fire control radar Eldledningsradar PE-2302 and a high-definition thermal camera for the gunner. The firing modes that it has are SACLOS and ACLOS letting the missile both be guided manually by the gunner and automatically by the FCS. The PE-2302 radar is a pulse doppler radar operating in the Ka band and has a max range of 30 km. The system is also outfitted with an IFF system letting the gunner know if an aircraft is friendly or not. As the Luftvärnsrobot 23 has both ACLOS and SACLOS modes for firing, the gunner gets to choose whether to manually guide the missile to the target using the thermal camera on the top of the mast, or whether to let the FCS automatically guide the missile to the target, giving it a sort of “soft fire and forget” mode where a second target can be engaged at the same time if it is located within the radar cone.

In War Thunder

In War Thunder, the BAMSE SRSAM would function a lot like the already existing Lvrbv 701. You would have no search radar to speak of and would as such be required to search for targets with your eyes, but unlike with the Lvrbv 701, you would have a thermal imager to assist you with searching for targets. The missiles would however be a lot stronger than the RBS 70 missiles that the Lvrbv 701 has with a much longer range and a higher velocity. Other than that the vehicle is much more manoeuvrable than the Lvrbv 701 letting you try to flank around the edges of the map to pick off aircraft and helicopters from an angle that they won’t expect. A problem with the vehicle is that the mast needs to be raised for the vehicle to be able to fire, or to even use the optics, and it is questionable at best if that mast can be raised whilst the vehicle is moving so you would probably have to stop and wait for the mast to deploy before being able to fire. An interesting gameplay mechanic would be the ability to fire at two different targets simultaneously with the radar being able to guide two missiles simultaneously, either at the same target or two different ones providing that the targets are both within the radar cone.
