On December 7, 1941, when the Empire of Japan attacked the United States Pacific Fleet at Pearl Harbor, many sailors with Hispanic surnames were among those who perished.
When the United States officially entered World War II, Hispanic Americans were among the many American citizens who joined the ranks of the navy as volunteers or through the draft.
Of the Hispanics who served actively in the European and Pacific Theatres of war, five would eventually earn the rank of rear admiral and above.

In 1941, Commander Luis de Florez played an instrumental role in the establishment of the Special Devices Division of the Navy's Bureau of Aeronautics (what would later become the NAWCTSD).
He was later assigned as head of the new Special Devices Desk in the Engineering Division of the Navy's Bureau of Aeronautics.
De Florez, who has been credited with over sixty inventions, urged the navy to undertake development of "synthetic training devices" to increase readiness.
During World War II, he was promoted to captain and in 1944, to rear admiral.
