The vice president of PepsiCo attended an American "exhibition" in Moscow in 1959 as part of an effort to convince the Soviet Union of the benefits of capitalism. Apparently Pepsi was a big hit, but there was a problem: Soviet money wasn't generally accepted worldwide. So the USSR bought billions of dollars worth of Pepsi by trading submarines, military ships, and a lot of vodka for the soda. For that brief time, PepsiCo had the 6th largest military in the world, until it sold all of the ships and submarines for scrap recycling.
