Optional elements of the S-400 (98ZH6E) include the 15I6ME–98ZH6E, which extends coverage 30, 60 and 90 km (19, 38 and 57 mi) from that provided by the 30K6E. The 96L6E has a detection range. The 40B6M is housing for the 92N6E or 96L6E radar. The Protivnik-GE is an anti-stealth UHF radar with a range. The Moscow-1 passive sensor is times more effective than the Protivnik, with a range Orion for a target-designation on-the-air defense system, and the Avtobaza-M and Orion+ Avtobaza add high-precision detection. The 1RL220BE versions were reportedly used for jamming. The -range S-200D Dubna (SA-5c) missiles and S-300 P-family radar systems can be used without additional command-and-control centers. S-300 (SA-20A, SA-20B) missiles may also be guided.
