High precision cruise missile 3M-14E

Cruise missile 3M-14E (see photo) complexes "Caliber-PLE", "Caliber-NKE", "Caliber-M" is equipped with a solid propellant launch engine in the tail part of which are located grating stabilizers. The TRDD-50B turbofan engine ("Product 37", 37-01E) is a small-size two-circuit turbojet of disposable application, unified for all Kalibr missiles, developed by the Omsk Engine Building Design Bureau (see photo). It is produced by NPO Saturn.

The 3M-14E rocket is equipped with a combined guidance system. Control of the rocket in flight is fully autonomous. The onboard control system is based on the autonomous inertial navigation system AB-40E (developed by the State Research Institute of Instrument Engineering). The missile control system includes a radio altimeter of the RVE-B type (developed by UPKB Detail) and a receiver of satellite navigation system signals (GLONASS or GPS). The radio altimeter provides flight in the mode of terrain rounding due to precise keeping the flight altitude: over the sea - no more than 20 m, over land - from 50 to 150 m (when approaching the target - a decrease to 20 m).

The missile flight follows a predetermined route, in accordance with intelligence data regarding target position and the availability of air defence assets. The missiles are able to overcome the zones of the developed air defense system of the enemy, which is provided by extremely low altitudes of the flight (with the rounding of the terrain) and the autonomy of guidance in the "silence" mode on the main area. Correction of the missile's flight path in the marching section is carried out based on data from the satellite navigation subsystem and the terrain correction subsystem. The operating principle of the latter is based on comparing the terrain of a particular area where the missile is located with reference maps of the terrain along the route of its flight, previously stored in the memory of the on-board control system. Navigation is performed on a complex trajectory, the missile has the ability to bypass strong enemy air defense / missile defense zones or difficult terrain - by entering into the flight specification of the coordinates of the so-called points of rotation of the route (up to 15 reference points) (see diagram trajectory).

Homing in the final section of the trajectory is carried out with the help of noise-protected active radar homing head ARGS-14E, effectively emitting low-profile small targets on the background of the underlying surface. Head ARGS-14E with diameter - 514 mm and weight 40 kg is developed in JSC "NPP Radar MMS". (Saint-Petersburg), has an angle of view on azimuth (bearing) of ±45°, on the angle of place - from +10° to -20°. The detection range of a typical target is about 20 km. Exceptional maneuverability allows with high accuracy to bring the missile on target.

The 3M-14E missile is equipped with a powerful 450 kg high-explosive high-explosive combat unit with an air blast option. A variant of the missile with a cassette warhead equipped with shrapnel, blast or cumulative attack elements for hitting square and long targets is developed.

According to published data, the missile's flight range, depending on the type of combat equipment is up to 2600 km. The flight range of the export version is limited to 300 km.
