    Soviet Launch Vehicles - New Data
 
    The March 18, 1988 issue of Aviation Week reports the first ever
Soviet statistics on their family of launch vehicles. Analysis of
these data indicates the existence of a previously unsuspected
booster, and screws up a lot of the standard assumptions about which
booster launched what. 
 
    The Soviet figures cover the period Jan 1,1970 to Jan 1, 1988
(except for the Soyuz booster where the period is 1972-1988 - maybe it
failed a lot in 1971!). They give total successful launches to orbit
and total failures to reach orbit, as follows: (RN= Raketa Nosityel',
= Carrier Rocket) 
 
Vehicle		Successes	Failures

RN Kosmos	317		14
RN Molniya	179		10
RN Tsyklon	61		2
RN Proton(4-st)	106		9
RN Vostok	88		1
RN Soyuz	554		12     (1972-1988 only)
  
    The figures for the 4-stage version of the Proton and the Mk II
version of the Tsyklon agree exactly with Western tabulations. (The
3-stage Proton and the Mk I Tsyklon are not being offered for
commercial use). The Mk II Kosmos has 322 launches assigned to it in
the period, so 5 must belong to some other booster. I suggest this may
include the 4 Kapustin Yar suborbital spaceplane tests. The Mk I
Kosmos was retired in 1977 and had 69 orbital launches in the period -
it is not discussed by the Soviets. The Molniya has had 180 orbital
launches in the period not 179 - maybe one of the low orbit failures
such as Kosmos-837 is counted as a failure to reach orbit. The real
problem comes with Vostok and Soyuz. 

    The new encyclopedia Kosmonavtika SSSR by V. Glushko published a
couple years ago confused the issue by attributing some types of
Meteor weather satellite to both Vostok and Soyuz boosters in
different parts of the book. We can only reconcile the Vostok numbers
if all the Meteor type satellites, including the sun-synchronous
launches, went on Vostoks. A further 11 launches previously attributed
to Soyuz must also be Vostoks; most probably the last 11
second-generation spy satellites of the Kosmos-22 and Kosmos-120
series. This leaves 647 launches still attributed by Western totals to
the Soyuz in the 1972-1988 period - according to the new Soviet
figures, 93 of these must actually be using a different booster which
is not any of the ones discussed above. Up to Jan 1,1988 I count 92
launches of the advanced 4th and 5th generation spy satellites
(Kosmos-758,Kosmos-1246,Kosmos-1426 types) and civilian missions based
on the same long-duration vehicle (Kosmos-1543 and Kosmos-1882
series), and I'm prepared to believe that a K-758 type mission has
been misidentified as a K-317 3rd generation mission. Since US
intelligence has not reported the existence of this new booster
(although the Pentagon document Soviet Military Power has accurately
reported other new vehicles) I suggest that a *Mk II version of the
Soyuz booster* has been introduced which is sufficiently different
(and has a sufficiently higher failure rate) that the Soviets have not
included it in their totals.

417.1Names change?SKYLAB::FISHERBurns Fisher 381-1466, ZKO3-4/W23Wed Mar 23 1988 15:078
    Is anyone else surprised/confused at the names of the launch vehicles?
    I had always believed that "Kosmos", "Vostok", "Soyuz", "Molinya",
    etc were the names of payloads.  Then suddenly a week or 2 ago I
    started seeing these names attributed to boosters as well.  Were
    these names really considered to be boosters in the West for a long
    time, or is it new?

    You are right that they are now applying payload names to launch
    vehicles. This appears to done by the Glavkosmos organisation to give
    the launchers 'sexy names' (sure beats Space Transportation System).
    
    They have usually used the most well known payload name as the launch
    vehicle name, although I don't know where Tsyklone came from. In the
    case of Kosmos, it is meaningless as they call most everything Kosmos.
    
    The DoD uses a simple number scheme, e.g. SL-4 is the Soyuz launch
    vehicle, but it is based upon the time when the LV was first noticed by
    the DoD. Fairly meaningless.
    
    I prefer a scheme devised by the late Dr Sheldon for the Library of
    Congress, of the form
    			X-n-x
    where	X sginifies the first stage(s), usually derived from a
    		  weapon system
    		n indicates the version or generation of the upper stage
    		x indicates any added escape or manouvering stage
    
    In this system, the Soyuz is the A-2. The A indicates it is derived
    from the original Soviet heavy ICBM. The 2 indicates that the upper
    stage is the second type to be used on the A booster. The Salyut
    launcher is the D-1, the variant used to launch geosynch satellites is
    the D-1-e since it has a transfer stage to carry the bird from parking
    orbit.
    
    Some time ago, I put together a list that correlated the letter series,
    the DoD numbers and the Glavkosmos names. If there is interest, I can
    type it in (no promises as to when).
