Groton — Capt. David A. Roberts will turn over command of the Naval Submarine School to Capt. Andrew C. Jarrett in a ceremony at the Naval Submarine Base Friday, July 19. 

Jarrett has previously commanded the USS Pittsburgh (SSN 720) and served at the United States Naval Academy. In July 2009, he reported to the academy in Annapolis, Md. and served as Fifth Battalion Officer until March 2013, when he became the Deputy Commandant of Midshipmen.

Roberts will next lead the Submarine Learning Center in Groton. He assumed command of Naval Submarine School in August 2011.

Roberts expanded the use of electronic classrooms, interactive courseware and blended, or combined, forms of instruction to increase and enhance the speed of learning and knowledge retention, according to the Navy. A unique Submarine Bridge Trainer was built at the school during his tenure. 

Roberts will relieve Capt. Emil C. Casciano as the commanding officer of the center on Friday, Aug. 2. Casciano, who is retiring after a 31-year career, has led the center since May 2011. Casciano directed a new qualification program for more than 1,000 instructors and established new information technology and networking courses, the Navy said.
