But Shoigu said test flights by 2019. How does a project get delayed past 2023 if it was supposed to be in pre-production phase by 2019.
Depends on the decision with putting the Tu-160M2 into production... if they do do that then it takes pressure off the PAK DA.
The Tu-95 is able to do the job fine but it is not a new design.
The Tu-160 is also able to do the job fine but is more expensive to operate and maintain and there are simply not enough of them to be a viable force.
The Tu-22M3M is not part of this discussion because it cannot perform strategic missions, but becomes related when you recognise that it also needs replacing too.
The question is... do you replace all three with the PAK DA, or restart production of the Tu-160 and use that and the PAK DA.
The question that has been answered... why bother with PAK DA at all when you are going to be building more Blackjacks why not replace all three aircraft (Tu-22/95/160M) with Tu-160M2?
If Tu-160M and Tu-160M2 don't have bomb capability then a bomber is needed.
Restarting production of Tu-160 will take time and money which will delay everything but will allow for instance the potential for the PAK DA to use some new emerging techologies.... like expanded widebody design for a large volume flying wing shape... even variable cycle jet engine that can operate in scramjet mode for high speed flight, and indeed photonic radar technology.

Or even a more sophisticated wing shape allowing a fixed wing design with perhaps warping technology to allow variable lift without conventional wing surface controls...
Aren't strategic bombers the most expensive platforms generally? Look at the B1 and B2 programmes. I would quite imagine that the Tu-160 was probably the most expensive platform from the Soviet Union.
Even per weapon delivered I suspect the nuclear subs would be the most expensive... including bases...
Now that they have been given upgrades I rather suspect the strategic bombers will have rather more practical use in conventional wars with conventional weapons... not something you can say for an SSBN or ICBM field.
2019 was thrown around for PAK-DA before all this Tu-160M2 nonsense. It was never realistic. Tu-160M2 was always 2023.
I rather suspect some department in Tupolev has always been working on new technology designs and wing/fuselage designs and propulsion configurations.
I rather suspect they have supercomputers and software that would allow thousands of designs to be prototype tested in a few hours... with the most promising models just a 3D printer and a wind tunnel away from a test...
I suspect their might be issues with the US likely to demand any PAK DA to be counted as a strategic bomber even if it is a joint strategic/theatre bomber which will effect deployable numbers.
