More cool stuff. Apparently the largest rocket motor ever built is still just sitting in a hole in the Everglades.
In the 1960’s the AeroJet company was considered as the possible supplier of solid-fuel rocket motors to be used as primary power plants for the Saturn I space booster. The idea, in simple terms, was to use a single, very large rocket motor in place of a number of smaller rocket motors. A complex was constructed in the everglades to manufacture and test the rockets.
The AJ260 was the largest rocket motor ever produced and during it’s testing, created the highest decibel noise level ever created by man. Its blast could be seen easily, 50 miles away in Miami. Despite it’s great power and sprawling manufacturing complex, the project was dropped by NASA.
