The An-10VKP successor was an Il-22M-11 "Zebra" or "Coot-B" for NATO. The Il-22 was based on the civilian Il-18D. It was developed by the Myasishchev Experimental
Machinery Plant (MMZ n°30) at Zhukovskiy, from 1970 on. The Il-18 airframe already had proved its adaptability especially with the SIGINT Il-20 "Coot-A," of which
two modified Il-20M platforms were also based at Sperenberg with the 39.ORAO (see > 3.4 Reconnaissance and Electronic Warfare).
The Il-18D-36 "Bizon" (designated Il-22 in service) or Article 36, were new airframes adapted by Myasishchev. Besides numerous antennas located on the fuselage, that aircraft
type could be easily identified thanks to the fairing located on top of the fin. Also, another characteristic was the long semi-cylindrical ventral fairing running almost
the full length of the fuselage.
Article 40 was an improved variant developed in 1977 with the designation Il-22M-11 "Zebra."
On this model, the length of the ventral fairing was significantly reduced, the latter ending at the wing leading edge root.
Most of the Il-22M also were modified new airframes; however, a few Il-22 "Bizon" were upgraded to the Il-22M standards.
Moreover, as new Il-18D were no longer available, former Aeroflot aircraft with a good remaining potential were in turn
modified into Il-22M due to a continuing VVS requirement for more airborne command posts.
Like all the Il-22s, the "Coot-B" from Sperenberg was camouflaged according to the art of maskirovka: "Il-18" markings on the forward fuselage
like the airliners, Aeroflot color scheme, and civilian registration ("CCCP-75913" s/n 0394011098). It made its first flight in 1982 and apparently replaced
the An-10VKP the same year.
More "Coot-B" sometimes were observed in the GDR. They were visitor aircraft like "75926" illustrated at left. The latter was photographed discreetly during a stopover at
Oranienburg in 1987. This Il-22M of the 245.OSAE was based at Osla-Krzywa in Poland and was used by the Commander-in-Chief, Western Military Operations Theater
(Zapadnyy Teatr Voyennykh Deystviy). Aircraft "75913" from Sperenberg was available to General Burlakov, commander of the Western Group of Forces (WGF, formerly GSFG)
at the time of its withdrawal from Germany in 1991. The former WGF airborne command post was still operational with the 8.ADON at Chkalovskiy in 1999 and it was finally
retired from service a few years later (> Photo).
