Australia, UK and US to collaborate on rapid rockets after Moscow claims to be firing its own in Ukraine

[AZrailwhale]

Wrong.

There was never an "attack" version of the SR-71 made. It was a paper only concept and never went beyond a basic concept as it was soon realized the very idea was rather pointless.

And what you are thinking of is the D-21, a recon drone that only carried cameras.

And those only did 4 missions in 2 years, every single one of them an utter failure.

Thanks
