Development

Following the 1989 definition contract which was completed in 1991, the then Bofors Missiles and the Swedish Defence
Materiel Administration (FMV) signed a US$200 million contract in May 1993 to develop the RBS 23 BAMSE MSAM
(Medium Surface-to-Air Missile system) for the Swedish Defence Forces.
The programme is a joint project between the then Bofors Missiles and Ericsson Microwave Systems AB. Saab Bofors
Dynamics AB developed the missile and the Missile Control Centre (MCC) and retains overall responsibility for system
integration. Ericsson Microwave Systems, under a separate US$80 million contract from FMV, is to develop the newgeneration
Giraffe 3-D surveillance radar and the fire-control radar, the Command, Control, Communications and
Intelligence (C3I) cabin-based system which is splinter proof and has NBC protection. Ericsson Microwave Systems
delivered its prototypes in 1997 with Saab Bofors Dynamics finishing full-scale development of BAMSE in 1998. In late
1999, a report was accepted by the Swedish Supreme Commander that procurement of three BAMSE batteries, which
would probably comprise a total of three central radar units and nine firing units plus missiles, would take place after
2003. An order worth SKr55 million was placed in late 1999 by the FMV for the RBS 23 BAMSE System with Saab
Bofors Dynamics AB.
In Swedish service, BAMSE will be an all-weather system that will fill the gap above the altitude coverage of
VSHORADS and SHORADS systems. Its range of well over 15 km and 15,000 m altitude capability makes the system
suitable for the protection of vital positions, such as airbases, naval bases and HQs, as the missile range exceeds most
attack aircraft's electro-optical controlled weapons' stand-off engagement distances.
BAMSE is also suitable for the protection of mobile army units because of its high mobility and the short reaction
times required for redeployment and preparation to fire. The system is air-transportable.

Description

A BAMSE battery will normally comprise a Surveillance Co-ordination Centre (SCC) and three MCCs. The SCC
comprises 3D-surveillance radar with a characteristic 8 or 13 m antenna mast and an integrated BM/C4I function. The
SCC co-ordinates and controls other type of air defence systems, and include such features as automatic tracking,
continuous threat evaluation and engagement planning. Up to four MCCs can be individually co-ordinated by an SCC.
The MCCs communicate with the SCC by cable, fibre optic cable or different types of radio. To ensure a reliable link,
the Swedish Army's standard TS9000 tactical radio system has been chosen with its high degree of jamming
resistance. The distance to the SCC can vary, but 15 to 20 km is regarded as normal. The MCC can carry out-group
and split tracking (with a capacity for more than 100 target tracks), track correlation, jammer triangulation and full
radar netting with other Giraffes.

The Ericsson Microwave Systems central surveillance Giraffe AMB radar and the three-man SCC constitute one unit.
The radar has an extendable mast, which can be set to either 8 or 12 m high, to allow it to be positioned behind
terrain obstacles. The signal processing will be state-of-the-art and the Giraffe AMB 3-D radar will ensure accurate
target information. The Giraffe AMB is stacked beam radar with instrument ranges of 30, 60 and 100 km, at elevation
coverage of more than 70º.

The MCC contains all the essential elements for the target engagement. It is towed by a cross-country vehicle,
which also carries the missile re-supply transloader. A deployment and fire preparation takes less than 10 minutes.
An elevatable mast on the roof of the MCC raises the fire-control radar, Thermal Imaging System (TIS) and IFF
sensor assembly. Guidance of the missile in flight is by command-to-line of sight and is performed via the Ka-band (34-
35 GHz) fire-control radar, which is a further development of the Ericsson Microwave Systems Eagle radar.
The capability of the MCC to acquire and track low-flying targets is enhanced by the radar's ability to `look over'
terrain obstacles. Target acquisition and tracking are initiated from the SCC by target assignment. The missile firecontrol
system presents the relevant information to the two operators housed in the NBC and splinter protected MCC.
The missiles are fired from an elevatable stand assembly, holding 1 SPX ready-to-fire missiles, located on the roof of
the MCC. Reloading the system takes less than four minutes.

The missile is of the high-acceleration, high-velocity type, with a maximum speed of about M3.0 and is fitted with a
pre-fragmented HE warhead with proximity fuzing and impact fuze. The weapon is stowed in a cylindrical containerlauncher
tube and will be capable of engaging all types of aerial targets - from small high-speed cross-sectional area
missiles, such as cruise missiles, anti-radiation missiles and Unmanned Aerial Vehicles (UAVs), to large slow crosssectional
area targets such as transport aircraft.

The MCC and SCC each have Built-In Test Equipment (BITE), integrated simulators and recording equipment. The
last two items will allow operators to practise combat system training without the need to fire any missiles.
BAMSE will be able to provide protection for air bases and other strategic installations such as population centres, as
well as mobile units, under all weather conditions. It will be fully air-portable in the Lockheed Martin Hercules C-130
transport aircraft in service with the Swedish Air Force.
