2,75" Precision Guided Rocket

Over the last years Kongsberg has developed a low cost guidance unit for unguided 2.75’’ rockets. This guidance unit can be used on all types of 70 mm or 2,75 inch unguided rockets being launched from different types of platforms.

The complete Guidance Unit for a 2´75 rocket includes all major subsystems such as seeker, missile computer, inertial measurement unit (IMU), battery, telemetry and canard actuator system (CAS).

The technology used in the seeker can either be a semi-active laser (SAL) seeker or a GPS unit. Kongsberg has also under development an Anti Radiation (ARM) seeker capable of homing onto radars and jammers.

The guidance unit greatly enhances the precision of the rocket, thus reducing the number of rockets needed to destroy a target.  The guided 2.75’’ rocket may be fired from a standard launcher, however, is prepared for interface to a future smart launcher.

A large number of test firings has been successfully performed utilizing SAL seekers, in addition several successful firings have been done with GPS seekers. The development is now in its end phase and the project is about to enter the qualification phase.
