absolutely not. If they didn't want to do this back in 2005, why would they do it now? Supersonic bomber is a thing of past. They are working on H-20, which will be the transformative platform they need.
The world has drastically changed since 2005. In fact it has drastically changed since 2017.
US B-1 is the most heavily used bomber in the fleet. It is extremely cost effective. People mistakenly think B-52s are more cost effective... That's a 1990s misconception utterly disproven by 20 years of experience in Iraq and Afghanistan.
Tu-22M is old. But it has a good airframe like the B-1 and most of all it is imminently build able. A 2-3 year program for modernization (new materials/sensors/munitions, rebalancing center of mass, new tooling) and it'll be done.
Sure H-20 when it comes out might be better... But how long? The world is changing very rapidly. Climate crisis, major power competition, etc.
Russia proved it. You need a tool not only for peer to peer, but for devastating weaker enemies for low losses. Russia has plenty of peer to peer level stuff like SSNs and Mig-31 but they are useless at taking out guys hiding in a tree with a MANPAD.
For what it's worth, Russian Tu-22M launching Kh-32s were still devastating.
