In the warm tropical waters of the South Pacific a Consolidated Catalina slowly taxies alongside a seaplane tender. The tender provided the PBY with maintenance often not possible to carry out at forward bases. The tenders ability to freely move from anchorage to anchorage well behind front lines made them a key aspect to successful seaplane operations.
The PBY was in many respects an outdate aircraft when the United States entered the Second World War. A mid 1930 design the aircraft was used for a multitude of missions including long range patrols, anti-submarine, anti-shipping, transport among others in nearly every theater of the war. Although initially considered obsolete the sturdy airframe lent itself to numerous improvement with eventually more than 3,000 being delivered before the wars end.
