perdon que este en ingles pero me parece a lugar.
The Kh-59M missile differs from the original model by having a twice as large warhead and by another propulsion system. Under the missile body has been suspended a small turbojet engine, the RDK-300 designed by the "Soyuz" [Union] OKB. The missile is brought up to speed by a powder-fuel accelerator located in the tail section and then continues flying propelled by that turbojet engine. Equipped with such a propulsion system, the missile has a three times longer range than the Kh-59
