Serbia plans a guided artillery rocket

Serbia's Yugoimport SDPR released preliminary information on an add-on guidance system for the EdePro 400 mm calibre R400 unguided rocket during Eurosatory 2012. Although the guidance unit is being developed as a universal one that would be potentially applicable to many types of unguided rockets, initial work is being focused on the R400.

Still classified by EdePRo as being under development, the basic R400 weighs 1,220 kg and can carry a 350-400 kg warhead over a range of up to 143 km. It has a circular error probable (CEP) of more than 300 m at maximum range. The goal set for the guided version is a CEP of 100 m at a range of 200 km.

Creating the guided version would involve installing a cylindrical guidance module about 700 mm in length between the warhead and the front end of the rocket motor. This would involve a modest increase in the length of the rocket, which is currently 6.5 m long.
