In the early 1960s Soviet Union sold titanium to the US believing they needed it for Pizza Ovens but instead they used it to build the iconic SR-71 Blackbird Mach 3+ spy plane

After all, they fraudulently possibly told their comrades that the United States was a lazy country that probably couldn’t even cook for itself. //

Titanium procurement during the Cold War was so vital to the US’ goal of defeating the Soviet Union that it had to secretly buy the metal from the very country it sought to vanquish. It was 1960 and Washington needed spy planes that could avoid detection in Soviet airspace by flying to the heavens. To make what would become the vaunted SR-71 Blackbird, Lockheed knew it had to build a light plane, but one that was strong enough to hold extra fuel to give it expansive range. The only metal that would do the job was titanium. The only place to get titanium in the needed quantities was the Soviet Union.

The US worked through Third World countries and fake companies and finally was able to ship the ore to the US to build the SR-71. //

“The airplane is 92% titanium inside and out. Back when they were building the airplane the United States didn’t have the ore supplies – an ore called rutile ore. It’s a very sandy soil and it’s only found in very few parts of the world. The major supplier of the ore was the USSR. Working through Third World countries and bogus operations, they were able to get the rutile ore shipped to the United States to build the SR-71,” famous former SR-71 pilot Colonel Rich Graham said in an interesting article appeared on BBC.
