ColdCollation, the next new bomber after the TSR2 was the Harrier that also met that requirement. Essentially this off-airfield or MOS operation was a 50s/60s fashion that pre-dated the June war and the Jaguar after that also had to have an austere runway capability.
The V- bomber disperse plan also fitted this concept with an essential difference; it was for a single Strike mission which could be mounted from bare-base by self supporting detachments. As mentioned above, the off-base logistics support for sustained operations was not cheap. Austere then gave way to post-67 war hardening.
