David Reed Conaghan, 57, passed away in his home on January 13, 2016. David was born on March 9, 1958 in Lima, Ohio. As a child, his love of science and rockets led him to a career developing missiles. He attended Ohio University, graduating with a Bachelor Degree in Science. During his time at OSU, he joined the Naval ROTC.

After graduation, he served in the Navy onboard the USS Waddell. After serving in the Navy, he joined General Dynamics. He led Standard Missile integration with the AEGIS combat system.

In 1992 and throughout the remainder of his career, he was with the Navy Advanced System Development Office, providing expertise and guidance for the design and testing of missiles and radars. Dave's father, a machinist, taught him a love of tools and cars, which Dave carried throughout his life. His joy was rebuilding his 1965 Mustang.
