Navy Builds Ramjet Missile with Model Rocket Engines and a Credit Card

[Randy Daytona]

U.S. Navy engineers at the Naval Air Warfare Center Weapons Division recently designed and flew a prototype ramjet missile in just six months. The engineers not only met their deadline, they flew the missile using off-the-shelf equipment, items so inexpensive they were paid for with a credit card. The result is a missile that could join the fleet in 3-4 years.

Outstanding work!
