Early in his Starfleet career, Grace served on the Saladin-class USS Alexander and Larson-class USS Lee. He was chief engineer of the USS Enterprise in the 2250s, under both Robert April and Christopher Pike. (Star Trek: Early Voyages) He was assigned to Enterprise until at least 2262.
- It's possible that Grace might have alternated engineering division-chief status with Caitlin Barry and Montgomery Scott, as all three were assigned to the ship at the same time.
