However I do think hypersonic technology will be very useful and improve Russian capabilities in a lot of areas but I don't think the cost is currently justified.
Just to clarify unless they are being used as a first strike capability the bombers will most likely get through because their flight times mean that SLBMs and then ICBM warheads will have obliterated the enemies air defences already and there wont be much coming up to meet them... further more on strategic missions current Russian bombers will be carrying 5,000km range cruise missiles so will not need to get very close to their targets anyway.
Personally I think a large super cruising flying wing with horizontal tail surface and some thrust vector capability to optimise trim and minimise drag would be the ideal future bomber solution. 5th gen engines, perhaps with a ramjet or scramjet booster for high speed sprints when needed, or perhaps long range low burn cruise.
Hypersonic technology should be financially supported but the focus should start with missiles (both attack and defence... ie cruise and SAM). When the technology is perfected then it can be adapted for fighter and bomber use.
Ultimately I would love to see a mixed 5th or 6th gen turbojet combined with a scramjet for operation from a conventional runway to orbit.
