Yangel OKB, designers of the frankly speaking ridiculously overpowered R-36 ICBM series was in Ukraine (including work for turning R-36 into Tsyklon and Dnepr satellite launchers), as well as teams responsible for Zenit carrier rocket (also used as boosters on Energia).

There was also other R&D and manufacturing works scattered across Ukraine, but outside of those and already mentioned Antonov they were mostly related to areas that weren't my hobby so I can't recite them from memory. Lots of heavy industry related to tanks and related vehicles near Kharkiv, at least.

EDIT: Also, post USSR breakup Ukraine ended up having to run a nuclear "weapons" program despite disavowing nuclear weapons - because they had full chain nuclear weapons industry from raw materials to final warhead assembly, and it was considered good idea to keep those people employed lest they be hired out by more militant places.

Especially whenever there is a current event with lots of news it is nearly impossible to find anything that is too close to the subject.

It would be great to be able to restrict search to older results, to avoid being in the shadow of more recent articles. Even adding "USSR" did not help at all, almost everything I got was related to recent events.

I've had this problem sooo many times in the past already. Google is way too focused on the latest information. Just yesterday somebody also pointed this out in a comment, about that website link that made it to the HN homepage that help find the right glue for two different materials, which was an example for an old rarely changing but still relevant website.

Anyway, on topic, here's a list that I found starting out from trying to widen the search from the starting point that I knew Antonov is Ukrainian:

Here is a video showing a pretty cool - albeit pretty unreliable, according to what I read - 1960s motorbike that was made in Ukraine: https://youtu.be/DvxcK645HF0 -- Wikipedia: https://en.wikipedia.org/wiki/Dnepr_(motorcycle). Dnepr (Ukrainian: Дніпро) is a motorcycle brand produced in Kyiv. I became interested in this bike while reading this RR story from a Ukrainian author - with lots of brilliant author-made painting-illustratiuons (if you open the inline images in a new tab you will find they are a much bigger resolution; It's worth scrolling through the chapters even without reading anything, just for those pictures): https://www.royalroad.com/fiction/54085/the-armorer-and-the-...
