USS Robalo - SS-273 (Submarine)

USS Robalo (SS-273), a Gato-class submarine, was named after the common snook, known as the ""robalo."" She was commissioned on September 28, 1943. During her first war patrol, Robalo operated in the waters west of the Philippines and encountered an enemy convoy. She attacked, but no enemy vessels were damaged.
On her second war patrol, Robalo was assigned to interdict Japanese tanker traffic from French Indochina to Tawi Tawi. She faced damage from Japanese aircraft bombing and fired torpedoes, but her sinking of a 7500-ton tanker was unconfirmed.
Robalo disappeared on her third patrol after a contact report indicating she had sighted an enemy battleship and two destroyers. She was presumed lost and stricken from the Naval Vessel Register on September 16, 1944.
The fate of the survivors is unknown, but one report suggests they were captured by the Japanese and later burned alive. In May 2019, the wreckage of the Robalo was discovered in the Balabac Strait.
