Creation History
The issuance of the order was the result of the policy of the US Navy , who wanted to receive standardized patrol flying boats based on a single project, but produced by various companies, since the naval enterprise “Naive Aircraft Factory” ( NAF ), which had modest production capabilities, was unable to meet the needs of naval aviation full volume [2] .
The prototype HRN-1 was put to the test in December 1929. In June 1930, the company received an order for 9 serial machines, deliveries of which began in late 1931. However, new orders from the fleet did not follow. Following the naval aviation plane, the Coast Guard became interested. In 1936, its responsibility was extended from 644 to 1,210 km from the coast, which required the acquisition of hydroplanes with a large radius of action. However , the PBY seaplane “Consolidated” , which was being introduced into production at that time, was considered too expensive for the Coast Guard, and eventually decided to buy an additional batch of upgraded “Hall” flying boats [2] .
Operation
The RN-1 aircraft entered service with the VP-8 squadron stationed in Hawaii, but in 1937 they were already decommissioned and replaced by the Catalins. In Coast Guard aviation, the RN-2 and RN-3 seaplanes arrived at the aircraft stations on the east and west coasts of the United States. In early 1942, they were transferred under the operational control of the Navy. Flying boats "Hall" received weapons and began to carry out systematic patrol flights in order to search for enemy submarines. They were also attracted to participate in search and rescue operations - the voluminous fuselage PH-2 / PH-3 allowed to place up to 20 victims. By January 1943, 9 aircraft remained in service, but during the following year they were replaced by more modern machines. The last RN-3 was decommissioned in March 1944 [2] .
