    air defense missile system nasams Roll-aircraft missile system NASAMS (Norwegian Advanced Surface-to-air Missile System) medium-range missiles designed to destroy air targets at low and medium altitudes in all weather conditions. The complex was developed by a Norwegian company "Norwegian Kongsberg companies" in conjunction with the American firm "Raytheon Company System" and is intended to replace the complexes "Improved Hawk" the Norwegian Armed Forces.

    Development

    complex was started in 1989 and finished in 1993 field tests. Since 1994, SAM goes to the Norwegian Air Force. To reduce the cost NASAMS SAM during its development are widely applied principle of modernization and unification of the elements of the complex with the existing weapons systems. As a means of destruction used rocket "AMRAAM" (AIM-120A) air-to-air company "Raytheon Company System". For target detection and fire control uses a modernized version of three-axis radar AN/TPQ-36A and fire control system of the Norwegian version of the complex "Improved Hawk" - NOAH (Norwegian Adapted Hawk).

    combat capabilities complex NASAMS exceed SAM "Improved Hawk". NASAMS able to simultaneously track and engage a greater number of targets, reduced reaction time and transfer complex of traveling to combat. The number of operating personnel is reduced four-fold, it has a greater degree of unification of equipment and the ability to interface with other systems.

    cost development and deployment by 1999 six batteries SAM NASAMS, according to the calculations of Western experts, is $ 250 million. Batteries are used for defense major air bases in Norway since 1999 modernized complex, designated NASAMS II, comes into service air defense units of ground forces in Norway. . In 2005. complex NASAMS purchased for the armed forces of Spain.

    Composition

    air defense missile system nasams Missile (AIM-120A) is based on the normal aerodynamic scheme and has a cruciform wing small area provides good maneuverability even at low airspeeds, and cruciform rudders in the rear. Management SAM by using the combined guidance system: command and in the initial part of the inertial flight path and active radar homing - on end. If the target is not maneuvering, the rocket performs autonomous flight using inertial block the path laid in memory of the onboard computer before starting. In the case of maneuvering targets on the ground served Zour correction command in accordance with a change in the current target coordinates. Teams are accepted onboard receiver command link antenna is located on the rocket nozzle block. Target acquisition radar homing SAM distatsii occurs at up to 20 km, followed by its active homing. The rocket is set quick micro-computer operating with a clock frequency of 30 MHz and has a memory capacity of 56 000 16-bit words.

    missile is equipped with high-explosive fragmentation warhead directed actions which undermine made active radar or contact fuze.

    Zour stored, transported and launched from the transport-launch containers. Package of six such TPK placed on the launcher performed on the chassis terrain "Scania" P113 (wheel formula 4x4 +2). In the Spanish army made launcher chassis "Iveco" (see photo). Loading missiles in TPK by using the charging machine, part of the complex (see photo). Missile launch occurs at a fixed elevation angle of 30 °. In the stowed position freight containers with SAM launchers are arranged horizontally. To improve the survivability of IP complex is expected dispersal of control point positions and radar at a distance of 25 km, while the relationship with the settings can be arranged on the cable, fiber optic or digital link. Communications equipment company "Thales Communication" on the basis of the switch 300 TAS (Tactical Eurocom switch) provides vysoskorostnoy exchange, encoding and decoding of traffic between network nodes, network interface with STANAG 4206 and ISDN.

    Multifunction Radar AN/TPQ-64, developed on the basis of radar serifs artillery positions AN/TPQ-36A, provides detection, identification and simultaneous tracking of up to 60 air targets, as well as guidance to the selected one to three SAMs. Radar AN/TPQ-64 - pulse-Doppler, three-coordinate, equipped with phased array and integrated interrogator "friend or foe" type Mk. XII. Radar provides an overview of the space by mechanical rotation of the antenna in azimuth and electronic scanning in elevation. The operation of the radar is made by computer control station fire. Radar beamforms needle type with low sidelobe and able to perform pulse compression, selection of moving targets, and the power to change the form of the emitted signal. Radar operates in the frequency range 8-10GHz (FOV in azimuth - 360 °, elevation - 60 °, the azimuth angle pace - 180 ° per second, positioning accuracy in range - 30m, on azimumu - 0.2 °, the angle places - 0.17 °, range resolution of 150m, azimuth - 2 °, elevation - 1.7 °). Deployment and provisioning - 10min. All station equipment installed on a towed trailer.

    To ensure combat operation in difficult noise conditions set NASAMS equipped optoelectronic guidance - NTAS (Norwegian Tracking Adjunct System).

    Information about the traffic situation on the radar (update period - 2) is transferred to the control of fire, which is composed of two high-performance computers, multipurpose modular design with remote display and control systems, equipment and data communications equipment (see photo). The console has two overlapping workstations (AWS) with the same controls. Each workstation is equipped with three screens, two of which displays all the air and the military situation, and the third - and the state of readiness of complex systems. Detailed information about the direction, speed and height of any goal can be achieved through the introduction of operator token bearing and pressing reading data for display on a display screen.

    Firing unit complex - Platoon, having armed with three PU with six rockets each, multifunction radar AN/TPQ-64 fire control station. Basic tactical unit SAM NASAMS - battery. It consists of three firing platoons (a common set of 54 missiles), combined into a network so that each of the three radar is able to replace all the others. Command post of the battery (located on one of the fire control points) can receive target information from higher headquarters and provide data about the traffic situation on the fire control platoon items. All 54 missiles can be fired at different targets within 12 seconds.

    complex NASAMS II differs from the prototype greater mobility - NASAMS II launchers are mounted on the chassis of terrain type Bv 206. Battery includes 4 platoon instead of three, six AN/TPQ-64 radar instead of three and 12 launchers instead of nine. NASAMS II software compatible with communications systems used in ground forces in Norway.
