Zozer recently released a version of their Kosmos 68 setting for Classic Traveller. It's based entirely on old Soviet sci-fi. The new version used the same page design and style as the original LBBs.

I've made a modified version of my Classic Traveller sheets to match this setting. They're fillable and free to download
