> And 35 years later the West is still unable to match Tu-160
Unable to match what? Aircraft is designed to serve a use case. B52 is planned to remain in service until at least 2050s, despite not winning any records. SR71 is a dazzling aircraft that is universally admired, yet none are in service today.
War isn’t a pissing contest to see who can have the fastest X, it is rather one where you find a bunch of most effective tools for the job.
Low flying approaches and cruise missiles were strongly reconsidered at the the because the MiG-31 had look-down shoot-down capability. We don't know if it would have been a better or worse option, we're dealing in counterfactuals.
Russia has few uses for the Tu-160 anymore. It's main use was to penetrate hostile airspace of near peer opponents. Since the fall of the USSR yes there is not much more use for that.
At the risk of “arguing with someone on the internet”, I think you may have your chronology backwards, since it seems the Tu-160 was designed to match the US aircraft you mention.
The Valkyrie was a late 1950’s to early 1960’s design with physical prototypes existing and flying by 1964.
The B-1A design began in 1965, with the first flight in 1974. This would have been the closest western analog to the Tu-160, since the B-1B derivative had a different focus - low-altitude terrain following - since it was believed that the high-altitude/high speed designs like the B-1A were vulnerable to newer Soviet missile designs. Stealth was also becoming increasingly important to US command due to the same concerns about missiles.
The design competition that begat the Tu-160 began in 1972, with a first flight in 1981. I’m not saying it’s not a great plane - by all accounts it is very capable - but US designs were not done in response to it.
You don't have to match exact speeds to match outcomes when it comes to bombing. What matters is what the platform is meant to achieve and how effective is it at its mission. A slower supersonic plane may be the superior overall platform, depending on the other aspects of the plane.
Russia made a hyper expensive show pony, when they could have built a cheaper, more effective platform at a lower speed. That's usually the kind of mistake the Americans make. The relatively high max speed of the TU-160 turned out to be entirely meaningless, they would have been better off building a different plane.
The TU-160 has a $200m+ price tag. That's $1.2b scaled to the US economic terms. It's something beyond hyper expensive for the Russians in relation to their economic capabilities and military spending.
The B-1A was cancelled. The TU-160 should have been cancelled.
Scaling prices of Soviet inventions to US economic terms using Russian prices is really, really absurd.
Which are carried by interceptor aircraft - meanwhile the long-term shift was clearly towards anti-aircraft missiles., and stealth was only a few years away. At this point the F/A-117 was already pretty far along in development.
Tu-144 was doomed by the whole system of socialism - and not really in a bad way. In a classless Soviet society there were no people for who paying 5x for the ticket to get 2.5x speed would be justified just because there was no mass inequality. In the west, there were some of those people and for a while (1980s and 1990s) that was enough for profitable operation of planes that came for free - but even then, that wouldn't work out if the airlines had to pay for planes.
If was an expensive toy West could somehow afford for a while, but Soviet Union couldn't.
That limited initial orders and almost killed the project until it was slightly relaxed enough to allow some flights to New York.
This sort of cynical approach to government and lack of dedication to public service is exactly what I see now taking root in the United States. Get to the feeding trough and grift your heart out. It's f--ing tragic.
Does it really need to?
Carrying 100 tons of bombs at mach 2... where?
A single F-18 can easily carry a 2Mt nuke, or two, mounted on some standoff missile with decent range on itself.
And USA, unlike USSR, has a network of friendly countries to host their airforce, and aerial refuelling infrastructure spanning the whole world.
