The USS Barbero, a fleet submarine, served as the platform for a groundbreaking experiment that combined military technology with civilian postal services. Utilizing a North American Regulus cruise missile, the United States Postal Service collaborated with the U.S. Navy to test the concept of delivering mail via missile. The launch took place from Cape Canaveral, Florida, marking an intriguing intersection of defense and civilian applications of technology. The payload consisted of 3,000 pieces of mail, which were sent to an area in Florida designated for the missile's recovery. This experiment not only displayed the capabilities of missile technology but also aimed to address potential future uses in rapid communication, especially in remote areas or during emergencies.The missile was designed to travel at supersonic speeds, allowing it to cover distances that would normally take traditional postal services much longer. Following its launch, the missile flew over 100 miles, achieving a successful landing. The test garnered significant media attention, prompting discussions on the implications of using military infrastructure for civilian purposes. It evoked a mixture of skepticism and intrigue regarding the practicality of missile mail and whether such a system could be implemented on a larger scale.
