Vought and Grumman were developing new torpedo bombers just before World War II started. Vought was slightly ahead on timing and used P&W R-2800 power for their design, while Grumman used the Wright R-2600 with a bit less power. But the F4U Corsair and the F6F Hellcat were coming, too, and BuAer wanted the two companies to concentrate on rapid production of fighters. Grumman built just under 2,000 TBF Avengers before turning production over to GM's Eastern Aircraft as the TBM and Eastern in turn produced almost 8,000 TBM Avengers before war's end. Vought was a bit ahead on design and testing of the F4U and turned over production of it's XTBU-1 design to a factory run by Consolidated at a Mack truck factory in Allentown PA. Disaster ensued as it took the factory almost two years to turn out the first Consolidated TBY-2 Sea Wolf torpedo bomber. In the end, only 180 TBY-2s were built and they only equipped a single squadron for a few months right at the end of the war. The paper superiority of the Vought design proved a mirage and the few TBYs were soon scrap, while the almost 10,000 TBF/TBM Avengers went on to serve the fleet in many roles (torpedo bomber, night attack, ASW, AEW, COD, etc.) for years.
