High School Cadets in Physical Science Class Learn Submarine Buoyancy from MMA Alum and Navy Vet

How do submarines use buoyancy forces? High school cadets in instructor Chris Schafer’s physical science class recently learned about firsthand experience on a sub from a special guest speaker — Rick Dehlinger, MMA Class of 1993 and MMA quartermaster.

Dehlinger tallied 10 years of U.S. Navy submarine experience on the Trident Nuclear Submarine and the USS Tennessee. He taught Schafer's class how submarines use buoyancy forces to ascend and descend by pumping sea water in and out of ballast tanks.  

The cadets were especially intrigued by the the discussion of the emergency blow, where the submarine breaches the surface at a high angle from rapidly pumping out water from the ballast tanks. Dehlinger also told the cadets about life on a nuclear submarine, training on submarine systems, emergency training, food on a submarine and the port of calls. 

Schafer, MMA Class of 1989, extended the invitation to Dehlinger to speak to the class, connecting the MMA brotherhood in the classroom.
