Commissioned in 1984, the Halyburton honors Pharmacist's Mate Second Class William David Halyburton, who died at Okinawa in May 1945 after repeatedly braving enemy fire to treat wounded Marines—finally shielding a critically wounded Marine with his own body when the enemy renewed their assault. His Medal of Honor was earned in a moment of pure selfless choice. The Halyburton served the Atlantic and Pacific Fleets until her decommissioning in 2011.
