TU-160M - AKA the B-1ski. Made in the 1970s, it is past dated.
The Russians are *trying* to get up to 30 working aircraft (https://en.wikipedia.org/wiki/Tupolev_Tu-160) Building two aircraft a year, that’s going to take a while.
How many B-1s are actually capable of taking off and delivering ordinance? Asking for a taxpayer friend.
