The Ford Mustang debuted at the New York World's Fair, the same week the U.S. Army's Transportation Corps completed a review of light-vehicle driver training standards.

Jerrie Mock landed her Cessna 180 Spirit of Columbus at Port Columbus airport after 29 days, 11 stops, and 22,860 miles, becoming the first woman to fly solo around the world. Her navigation and communications equipment, HF radio, ADF, and a sextant, was drawn directly from Cold War general-aviation standards shaped by military surplus.

The FIM-92 Stinger helped win the Cold War by turning Afghan mujahideen into a credible anti-aircraft threat. By 2023, the United States almost ran out of them, because Raytheon stopped making them for 13 years, and the first 10 months of Ukraine support burned through the remaining stockpile.
These weapons were built to fight a war that everyone prayed would never happen. The Minuteman III has been on alert since 1970. The Typhoon-class carried enough nuclear warheads to destroy a continent. The Davy Crockett could be fired by three soldiers. Most of them have been waiting for 40 years. Here are 10 Cold War weapons built exclusively for World War III.
The MiG-31 was designed to catch the SR-71 Blackbird. It is still the fastest fighter in any air force. The Foxhound's Zaslon phased-array radar, the first ever installed in a fighter, can track 10 targets and engage 4 simultaneously at ranges exceeding 200 miles. Here is why Russia still flies a 1980s interceptor, and why the MiG-31BM carrying a Kinzhal hypersonic missile has changed what the aircraft means to modern warfare.
Nineteen armies on four continents chose the Leopard 2. No other Western tank comes close to this export record, and the reasons go far beyond German engineering.
