I cannot find any reference to this online, but your post reminded me of a similar message to the Russians from the same era. The roof of the Northrop plant in Hawthorne, CA (now SpaceX) had "Yeb Vas" written in some fashion so as to be visible only from the ISR satellites of the day.

It's also mentioned by one of the designers here:

This is a meaningless phrase and it does not translate to anything meaningful in Russian. They should have done proper research before wasting time on this nonsense.
