Here's a list of the Russian nuke bomber sorties, by date and region, in case you want to do a little aerial wargaming with jet fighters and bombers:

AirWar C21 released a bomber supplement in the last few years, which would be useful for gaming.
Sadly, 1/600th and 1/300th scale Cold War, Russian bomber miniatures are a bit rare, but perhaps someone will read this and take concrete steps to address the situation.
You can also drop down to 1/1200th scale, but the cost of aircraft in this scale are a bit high, relative to those of other scales, in my opinion. Still, minis selection for Russian bombers is better, and it's a good option for lots of wide-ranging maneuvering on the tabletop, too.
GHQ also produces some in 1/2400th scale, as well, which are quite nice, and reasonably priced.
I'd recommend avoiding the 1/3000th scale aircraft, since in my opinion cardboard counters look better, and are more accurately "sculpted". They are significantly cheaper too, and you can easily produce your own from line drawings found on-line, if needed, and/or you are on a tight budget.
