11K37 was based on the 11K77 (Zenit) launcher.
There was also a "light" version of Zenit, called 11K55.

This seems a lot like the "Heavy" Zenit concept, except that the core here only has 3 thrust chambers.

What engine did this project use?
Been looking for more details on the Kvant program that used RD-120 engines.

thx for info Dmitry info looks very interesting.

If I remember correctly, it uses a derivative of the RD-170 that looks like the later RD-180, but I could be wrong. In any case the information can be found on the NK forums (translation is a PITA though...  :-X): http://www.novosti-kosmonavtiki.ru/phpBB2/viewtopic.php?t=10895

Is that 3x NK-33 on the center (second) stage?

There's a bit on this in English at http://www.russianspaceweb.com/zenit.html and more on the engine in Russian at http://engine.aviaport.ru/issues/63/page34.html .

Do we have any info on the Lite Zenit 11K55?

As an "unknown project", the first details of the 11K37, 11K55 and 11K66 Zenit variants were given 16 years ago in the paper IAA-95-1AA-2.2.09.

Only general comments about these variants were given, but the 11K55 and 11K66 variants were to be two-stage vehicles (the differences between these and the two-stage 11K77 which we know and love were not given, but the second stage was probably different for each variant), while the 11K37 would have a variable design, with clusters of two, four or six Zenit first stages to give the payload range 30-60 tonnes to LEO.

The early history of the project 11K77 is described here:
http://epizodsspace.airbase.ru/bibl/kb-ujn/05.html
11K66 LV had essential differences from projects 11K77 and 11K55 as was based on 15A14 ICBM . Whereas 11K55 and 11K77 were original workings out.
As to a variant 11K37 with the six first Zenit's stages, that, as far as it is known, it didn't exist.

http://epizodsspace.airbase.ru/bibl/kb-ujn/05.html
1166 LV had essential differences from projects 1177 and 1155 as was based on 1514 ICBM . Whereas 1155 and 1177 were original workings out.
As to a variant 1137 with the six first Zenit's stages, that, as far as it is known, it didn't exist.


The "six first stages" 11K37 vehicle certainly existed insomuch as it was clearly considered by the Yushnoye bureau (whose staff presented the 1995 paper).   It might not have progressed very far, but clearly it was part of the thinking when the Zenit family was initially being considered.

Probably, such variant was considered at the earliest stages of the project 11K37, in 1970-75. However neither in the project 1983, nor in projects of 1985/88/89 years about it there are no mentions. The variant 11K37 with four blocks should deliver to LEO 54 mt payload. And the rocket with six blocks wasn't necessary.
