He was posthumously awarded the Navy Cross, his citation reads:
The President of the United States of America takes pride in presenting the Navy Cross (Posthumously) to Seaman Second Class Frank Olga Slater, United States Naval Reserve, for extraordinary heroism and devotion to duty in action against the enemy while serving as a Gunner aboard the Heavy Cruiser USS San Francisco (CA-38), during an engagement with Japanese naval forces near Savo Island in the Solomons on the night of November 12 and 13, 1942. Courageously refusing to abandon his gun in the face of an onrushing Japanese torpedo plane, Seaman Second Class Slater, with cool determination and utter disregard for his own personal safety, kept blazing away until the hostile craft plunged out of the sky in a flaming dive and crashed on his station. His grim perseverance and relentless devotion to duty in the face of certain death were in keeping with the highest traditions of the United States Naval Service. He gallantly gave up his life in the defense of his country.
