The construction of the XP-59A prototype, also known as c/n 27-1 with serial number 42-108784, began three months after the contract was signed, with the work conducted in a toolshop leased from the Ford Motor Company. Despite efforts, delays, particularly in the delivery of engines, hindered the project. The aircraft was finally packed in crates and transported to Muroc on 12 September 1942.
After re-assembly and pre-flight checks, Bell’s chief test pilot, Robert Stanley, conducted the first flight on 1 October 1942. This inaugural flight was cautious, with the landing gear locked down and at a low altitude of just 25 feet. The same day, three additional flights were completed, followed by four more the next day, during which the aircraft reached an altitude of 10,000 feet. However, the 9th flight did not occur until 30 October due to necessary modifications to the undercarriage.
The XP-59A faced numerous issues, particularly with its engines, which were heavier than expected and prone to problems like detached turbine blades, overheated bearings, and fuel pump failures. The maximum speed achieved was 404 mph (650 km/h) at 25,000 feet, which fell short of expectations. The engine installation also caused significant aerodynamic interference, leading to directional instability and making the aircraft an unstable gun platform. Despite these challenges, work continued on the P-59, and solutions were sought for its various issues.
