A protracted development period left the Brewster SBN-1 an obsolete machine when America went to war in December of 1941.
Detailing the development and operational history of the Brewster XSBA-1 / SBN-1 Carrier-Based Dive Bomber. Entry last updated on 5/5/2016. Authored by Staff Writer. Content ©www.MilitaryFactory.com
For the XSBA-1, Brewster engineers adopted a deep, tapering fuselage with the powerplant conventionally set at the front of the aircraft driving a three-bladed propeller. The pilot and crew sat under a greenhouse-style canopy with good views of the surrounding action. The aircraft featured monoplane wing appendages that were mid-set along the fuselage sides. The main landing gear were retractable into the sides of the lower fuselage (ala the Grumman F4F fighter) utilizing a rather complex-looking strut arrangement. The tail was capped by a single vertical tail fin and low-set horizontal tailplanes. Its crew numbered three- pilot, navigator and gunner - with the latter crewmember seated in a position at the rear of the aircraft manning a sole, trainable 0.30 caliber machine gun. Perforated split dive-flaps were installed on the wings to retard the descent of the aircraft when on its attack run. An internal bomb bay supported a single 500lb bomb. Power was served through a Wright XR-1820-22 Cyclone radial piston engine of 950 horsepower and performance specifications included a maximum speed of 255 miles per hour, a range out to 1,015 miles and a service ceiling of 28,300 feet.
By the time of the Japanese surprise attack on Pearl Harbor on December 7th, 1941, the United States Navy was still in the process of accepting delivery of these Brewster machines from the Naval Aircraft Factory (NAF). The aircraft proved of little value with the fast-paced war to follow, quickly usurped by more modem and capable dive bombers that followed and, as such, production stood at just the 30 aforementioned examples as well as the single prototype model.
Brewster's life as an aircraft contractor ended on April 5th, 1946 as the company struggled to profit after the war's end. Aircraft production at the Naval Aircraft Factory - set up by the USN in 1918 solely to produce its needed aircraft - ended in early 1945.
