There was a subtle difference in the shape of the LOK OM compared to that used on Soyuz. Easy to compare in this image: the second module from the left is a LOK OM, with its lower section slightly wider than the upper one.

Thank you Dmitri for posting these images.

Is there more information on the evolution from the RLA-150 launcher to the Vulkan and Energiya derivatives?

Also, what is the difference between the LKE and the LEK designs in overall mass, capabilities or dimensions?

What was the payload capacity of the Vulkan in its latest iterations, and could it send a fully loaded LEK to lunar orbit (OISL)?

In the image with the LKE Blok V in the Podsadka docking with a Soyuz, is that the same Soyuz configuration as the EPAS/ASTP Soyuz 19?

Thanks

Hi!
Apparently, LEK and LCE are one and the same.
Most likely, 7K-TM was used for "Subsidence." Soyuz-19 also belonged to the same family.
By the time the Vulcan project was stopped (1989), this launch vehicle could deliver a payload weighing 198 tons to LEO, and 43 tons to lunar orbit. More: http://www.buran.ru/htm/38-3.htm#vulkan

On the development of LVs Vulcan and Energia below will write in more detail.

The family of RLA launch vehicles developed intensively in the period 1974-76, and even further.
"Energy" evolved from RLA-130, whereas "Vulcan" evolved from RLA-150.
Part of the history of RLA development is set out here: https://forum.novosti-kosmonavtiki.ru/index.php?topic=3349.msg127542#msg127542
A general view of the last variant of "Vulcan" can be seen in the attached picture.
The evolution of the "Energy" configuration can be seen in another picture.

These plans posted by Dmitry, they look heavy for an N-1 with Blok D, LOK.

Maybe they were intended for an N-1 equipped with a larger version of the Blok D braking stage, or for a two-launch scenario, where the LK V-IV or the TLK-D were launched by one N-1, and the crew spacecraft LOK was launched by another?

In particular the TLK-D looks truly heavier, includes a docking cone for an advanced version of the LOK, and a LRV (crewed Lunokhod). (It would be interesting to see what the design of such LOK would look like).

Thanks

The TLC project was developed simultaneously with the LCM project and was its competitor. Both projects provided for two launches of N-1F-type missiles. Both options provided for the assembly of the complex in lunar orbit (LOR). For TLC, it was supposed to use two manned ships (LOK and TLC-D), launched separately. Only one manned component (L3M ship) was used for N-1-L3M

The project of the lunar expedition with the LK "option B-IV" was considered in 1965-66. It provided for one launch of the N-1 rocket, in which the 4th stage (Block G) was replaced by a cryogenic stage. Due to this, the mass of the ship delivered to the moon significantly increased.

During the studies on the LKM project, schemes with three N1 starts were also considered.

Many thanks to Dmitry V for posting the plans of the LOK NO and the TLK in the N-1F launcher!

So the scheme was to replace the N1 L3 with a two-launch misión scenario, with the original LK lunar lander replaced by a mini space station module NO (scientific compartment) and launching of a heavier TLK lander in a separate N1.

What would have been the designation of this misión plan?

And what would the appearance been of the complex LOK, NO, TLK, enlarged Blok D docked in orbit around the Moon?

Thanks.

The Soviet lunar manned project survived 1974. V.P. Glushko canceled the N-1, but not the manned lunar expedition.
Moreover, Glushko considered this project his main task. Since 1974, the development of the Lunar Expeditionary Complex (LEK) has been actively carried out.
Different options were considered, including expeditions with one and two ships. The option of assembling LEKs in low-earth orbit with the launch of several reusable systems (future Buran) was also proposed.

The expedition scheme with one LEK ship provided for one launch of a super-heavy RLA-150 launch vehicle. But a less preferred two-ship scheme (Landing Expeditionary and Orbiting Expeditionary) was also considered. They were supposed to be launched by two missiles of the RLA-130 type.

A few more flight schemes (from top to bottom)
1) Single-launch single-ship
2) Two-launch single-ship
3) Two-launch two-ship
