Mr. David Legg has been named the new Combat Survivability Division Director of the Naval Air Warfare Center-Aircraft Division (NAWC-AD), as well as the new Navy Principal Member of the Joint Aircraft Survivability Program (JASP). He assumes these positions from Mr. Bill Dooley, who retired last year.

With more than 36 years of both Government and industry experience in the aircraft survivability discipline, Mr. Legg previously served as NAWC-AD’s Fixed-Wing Aircraft Branch Head, as well as the Survivability Team Lead for many U.S. Navy aircraft, including the P-8A Maritime Patrol and Surveillance Aircraft. In addition, he was chosen to be a Naval Air Systems Command (NAVAIR) Associate Fellow in 2011 and was the recipient of the Gormley Combat Survivability Award for Leadership from the National Defense Industrial Association in 2015. Mr. Legg holds bachelor’s degrees in mathematics and mechanical engineering from Saint Vincent College and the University of Pittsburgh, respectively.


LT Tyler “Sloth” Harrell has become the newest addition to the Joint Aircraft Survivability Program Office (JASPO) and is now serving as Military Deputy Program Manager (PM). A pilot by trade, LT Harrell graduated from Western Michigan University in 2011 with a B.S. in aviation flight science, along with his commercial multi- and single-engine pilot’s licenses. In 2013, he received his Navy commission from Officer Candidate School and then started flight training as a Student Naval Aviator in Pensacola, FL. In 2015, LT Harrell received his “Wings of Gold” from Helicopter Training Squadron 18 and was sent to San Diego, CA, to learn how to fly the Mighty MH-60S Knight Hawk with the “Merlins” of Helicopter Sea Combat Squadron 3.

LT Harrell then reported to Helicopter Sea Combat 14, where he immediately deployed aboard the USS John C. Stennis in support of the 2016 WESTPAC/RIMPAC Cruise. Over the next 3 years, he trained to become a fully qualified aircraft commander and led the squadron on its first “Around the World” deployment in 2018.

Now at JASPO, LT Harrell will be leveraging all of his operational and field experiences to support and enhance future aircraft survivability capabilities.


For those in the community who may not have heard, long-time aircraft survivability expert Mr. Nickolaos Caravasos passed away last year at the age of 80. A native of Zoupena, Greece, Mr. Caravasos immigrated to the United States at an early age and became the first in his family to finish college, earning a B.S. in mechanical engineering from the University of West Virginia and a master’s in management and organizational dynamics from the University of Pennsylvania.

Mr. Caravasos worked for The Boeing Company for almost 40 years and became a well-known specialist in composites and survivability. After his retirement from Boeing, he continued his work as a consultant for the Institute for Defense Analyses. He authored many technical publications and presentations and received numerous awards and honors during his career; and in 1998, he was recognized by the American Institute of Aeronautics and Astronautics as a “pioneer and [then] 30-year veteran of design and implementation of survivability improvements to fixed- and rotary-wing aircraft.”
