A rare sight in Iloilo during the 1910s — a U.S. Plunger-class submarine docked for training and familiarization missions. These early A-class vessels were among the first submarines of the U.S. Navy, used to teach new submariners how to dive, navigate, and operate beneath the sea. Many of them were stationed in the Philippines before World War I, making this moment a remarkable piece of Iloilo’s early maritime history. #submarine #hugotadventuretv #ILOILO #IloiloHistory #fypviralシ #IloiloCity #
