130M connected to Russia's unified combat network "The new KSS-130 communications package has become one of the key innovations in the Yak-130M modern combat trainer from our United Aircraft Corporation," said Rostec. The system allows the aircraft to transmit tactical data to other aircraft and ground command positions in real time. The package connection links the Yak-130M to unified battle control networks, transforming it from a single operator to a node in a distributed battle network, one of the central requirements of modern warfare.
