That's my fault. Is the above image yours Gunter? I'll assume so as it's on one of your links, so I'll change and accredit. Thanks!

Wasn´t this also the last Oko early warning satellite?

Object A is now in:
35898.3km x 35932.1km x 2.27°

IMHO:
Object A = S/C
Object B = DM-2 adapter
Object C = Proton-K 3rd stage
Object D = DM-2

I would expect Object E and F (the 2 ullage motors) to show up sooner or later

Amazing read - especially the history - via this article by William Graham:

Russian Proton-K to complete 45 years of service with US-KMO satellite launch
http://www.nasaspaceflight.com/2012/03/russian-proton-k-rocket-launch-us-kmo/

Very fitting for its final launch.

The Proton rockets 8K82 flew from 81/24?

USSTRATCOM now says:
 Object B = SL-12 R/B (1) ie Proton-K 3rd stage
 Object C = SL-12 PLAT ie DM-2 adapter

and also says that Object B re-entered April 1, at 1333UTC +/- 1 minute over 47N 65W (Canada East Coast)

(Object C, the DM-2 adapter, decayed on March 30)

Better late than never: the rollout and the launch.

I've just found an old news about this spacecraft on Khartron-Arkos website :

Quote
24 Aпреля 2003

Выведено на орбиту изделие 71Х6 № 7126 универсальной системы наблюдения за земной поверхностью "Око-1" (Россия). Из-за возникших неполадок изделие в эксплуатацию не поступило.
Самое долгоживущее изделие 71Х6 № 7124 было выведено на орбиту 25.08.2001 г. и продолжает функционировать по сегодняшний день.
Начата модернизация СУ изделий 71Х6. Пуск изделия № 7128 с модернизированной СУ запланирован на 2010 г.

http://arkos.kharkov.ua/news.php?a=3

More from Khartron:

http://arkos.kharkov.ua/sutkm_e.php

Control system for spacecraft 71Х6

SC 71Х6 is orbital segment of the universal system "Oko-1" for Earth observation (Russia).
Rocket and space complex and spacecrafts 71Х6 of this system were developed by RPO named after S.A. Lavochkin.
Since the year 1991 seven SCs were injected into geo-stationary orbit by LV «Proton» with boosting stage.

Name    Product    Date of launch
Kosmos-2133    No.7120    14.02.1991
Kosmos-2224    No.7121    18.12.1992
Kosmos-2282    No.7123    07.07.1994
Kosmos-2350    No.7122    29.04.1998
Kosmos-2379    No.7124    25.08.2001
Kosmos-2397    No.7126    24.04.2003
Kosmos-2440    No.7127    27.06.2008

Satellite characteristics:

    mass 2600 kg,
    operation life 5-7 years.

The satellite is equipped by IR-telescope with diameter of main mirror of 1 m. Length of blend is 4,5 m. {this is probably focal length}

Control system allows to solve the following tasks:

    damping of initial angular rates and building of single-axis orientation on Sun;
    building of three-axis basic orientation on Earth;
    precision orientation in phases of implementation of target task;
    correction of orbit;
    checking and diagnosis of equipment with automatic parrying of failures.

Control system characteristics:

    accuracy of orientation no worse than 8 min of arc,
    angular rate of stabilization no more than 0,0001 deg/s.

This is the only thread that mentions Oko, so I am posting this stuff here. Someone on the NK forum visited Yepatoria in the Ukraine, and found this:

http://kik-sssr.narod.ru/p785.htm

This is probably a first generation variant, those flown on the Molniya LV. According to the NK forum, it is missing a module.

just noted that the 2 ullage motors have been catalogued
38101     COSMOS 2479     2012-012A
38102     SL-12 R/B(1) 2012-012B (Proton-K 3rd stage, reentered in April)     
38103     SL-12 PLAT 2012-012C (DM-2 adapter, reentered in March)   
38104     SL-12 R/B(2) (DM-2)     2012-012D
38105     SL-12 R/B (AUX MOTOR)     2012-012E
38106     SL-12 R/B (AUX MOTOR)     2012-012F

BTW, the spacecraft has just been relocated to 166°E

Apparently K-2479 has failed this April after just 2 years in orbit....

Press reports say the last geosync missile tracker has now failed.

“Око-1" лишилось зрения
У России не осталось геостационарных спутников для контроля ракетных стартов

There are reportedly two remaining sats in molniya orbits [6 needed for full coverage] and a new design geosync bird in fabrication.
