L370 Vitebsk (Russian Л-370 «Ви́тебск», named after Vitebsk city in Belarus) is a Russian-made DIRCM system used mostly on military helicopters. With development beginning in the early 2010s, deployment started in 2015, the system saw extensive use in the 2022 Russian invasion of Ukraine by the Russian Air Force, while it is also offered for export under the name President-S, (Russian «Президе́нт-С») being used by the Egyptian Air Force on its Ka-52s, the Algerian Air Force on its Mi-17s, Mi-26s and Mi-28s, and the Belarusian Air Force’s Mi-8s.
It is used on helicopters Ka-31 (variant L370E31), Ka-50 (L370V50), Ka-52 (L370V52), Mi-8MT (L370E8), Mi-26 (L370E26L), Mi-24 (L370V24), Mi-28 (L370V28) and attack aircraft Su-25SM3 (L370K25), while being developed for a range of further platforms like aircraft Il-76, Il-96, Tu-204 and helicopter Mi-38 (variant L370V38S).
