Among the takeaways from this are emphases on a 'whole of society' effort toward defence of the realm ~ good luck with that ~ and an awareness that absent nuclear weapons it'll be drones doing the dirty work that we can't or won't.
I emailed the business lead at our national effort at deploying maritime autonomous drones over a fortnight ago, whose web page...
...boasts of working to gain the trust of the small-and-medium enterprises expected to provide the innovations sought in the review.
Clearly not hard enough, however, if it meant replying to emails.
In the US companies manufacturing maritime drones use tags like 'Fight Tonight'. The public were invited to participate in the UK defence review, and I've suggested 'Can we get back to you?' instead.
