/RVV-AE. Tracking distance is extended up to 70 km. ;N001VEP (RLPK-27VEP) :Fitted to Su-30MK2 and the upgraded Su-27SMx. Can simultaneously track 10 targets and engage one, with an improved version able to engage two. It can provide mid-course guidance for the R-77/RVV-AE up to 40km. In air-to-air modes, it nominally has a 50% probability of detecting a 3 square meter target at 100km, with the longest range search mode being able to detect such a target at 150km. The radar also has four surface search modes, including a low resolution synthetic aperture surface imaging mode and a ground moving target indicator mode with a 90km range against tanks. The radar can be used to cue targets for missiles such as Kh-31A,
