And there were the notorious TU-4 copies of the B-29.
And crews of those B-29 that were used to make a copy of, were interned,
because Russians were 'neutrals' in war with Japan. To top it up, expenses
for keeping interned crews were billed to US and to my surprise, those
gallant allies were paid, just as they were paid for several crews from
Jimmy Doolittle's flight over Tokyo.

but never "they" walked on the moon ...
There are those who think they crashed there though.
There might be those who believe it, but I understand that their 'Moon
Rocket' never wandered too far from the launch pad.

When pictures of their ballistic missile/turned satellite launcher, the
Sapwood, appeared in the West, there was a comment that 'there would never
be another rocket that would require 32 motors to start simultaneously and
operate without a hitch'; there were 10 fixed main engines and 12 gimbaled
verniers. The probability of success did not favor such a design. However,
the 'Moon Rocket' exceeded that engine count. I understand that moon missile
was named 'Tzar Rocket' by engine people. The rational for name is:

1.. There was a Tzar Bell, the largest bell in the world, but it never
rang, because it cracked during casting.
2.. Then there was a Tzar Cannon, the largest in the world, again, but it
never fired. It cracked during casting, too.
3.. Then came the Tzar Rocket.
In mid 90s a Frenchmen wrote a book about Russian Moon Rocket and that book
was translated into English around year 2000. It contains photographs of
handwritten notes and sketches which are supposed to be from diary of Chief
Engineer, Korolev (he died before or soon after second failure, presumably
from natural causes); the same guy was Chief Engineer on Sapwood and most
subsequent missiles. One of sketches points to one of engines that failed
during first try. However, people who built engines are adamant that engines
operated flawless. According to them, in first test one of engines was
commanded to shut down without good reason. In the second test missile went
unstable (i.e. went to corkscrew flight) and had to be destroyed. There was
a whole bunch of engines built, but there was no other missile built, the
project was abandoned.

Even Frenchman admits that there were only two missiles built and both
failed quite miserably.
