The Hall XP2H-1 was an American prototype four-engined biplane flying boat of the 1930s. Intended as an experimental very long range maritime patrol aircraft, a single example was built. The XP2H-1 was the largest four engine biplane aircraft ever procured by the US Navy. [1]

Development and design

In 1930, the United States Navy ordered a single example of a large flying boat from the Hall-Aluminum Aircraft Corporation, to meet a requirement for an experimental very-long range patrol aircraft. The resulting design was designated XP2H-1 and was a four engined biplane. It had an all-aluminium hull, a scaled up version of that used in Hall's smaller PH flying boat, which accommodated a crew of six. The wings were of fabric skinned aluminium construction and were of trapezoidal shape. The engines, Curtiss V-1570 Conquerors were mounted in tandem push-pull pairs between the wings.[2][3]

The XP2H-1 first flew on November 15, 1932, and was extensively tested, demonstrating excellent performance, being 11 mph (18 km/h) faster than predicted.[4] It was possible to cruise on just two engines to extend range, and in 1935, the XP2H-1 was used to carry out a non-stop flight between Norfolk, Virginia and Coco Solo, Panama Canal Zone in 1935, taking 25 hours and 15 minutes to fly the 2,000 miles (3,200 km).[5] It was destroyed later in the year attempting a landing in open water.[6] No further P2Hs were built, with the US Navy equipping its patrol squadrons with smaller flying boats such as the Consolidated P2Y.
