Hi everyone

In 1939 a competition was made for a replacement of the Douglas TBD Devastator.
There where six manufactures Grumman / Douglas / Vought / Hall / Brewster & Vultee.
I have only the Grumman Avenger & Vought Sea Wolf and the Douglas , missing the rest !
There where thirteen designs in total.
Anyone knowing more

according to Naval Fighters 33, the vought XTBU-1 Sea Wolf placed second in the competition to the XTBF-1 Avenger, however one XTBU-1 was ordered, and following early testing, showed a 50mph speed advantage over the Grumman plane. as a result the Navy ordered 1000 TBU-1s.
vought, however, was fully occupied with the F4U corsair, so sub-contracted the TBU to vultee, who converted a truck factory in Allentown, Pennsylvania, to produce it.
delays in converting the factory, and training the workforce meant the first production TBY-2 did not fly until august 20th, 1944.
180 more were completed by the time the contract was cancelled due to the war's end. due to the production delays, the Pratt and Whitney R-2600 'B' powered TBY-1 was replaced by the TBY-2, powered by the uprated R-2600 'C' engine.

cheers,
Robin.

For SD-114-6


Vought mentions the V-174A/B/C/D/D-1 in their responses to SD-114-6

XTBU-1 Mockup 76 Years Later Part One
Vought's entry in the competition to replace the Douglas TBD torpedo bomber became a footnote in history due to the success of it's stablemate the F4U and the lack of production space at the factory. The aircraft was sleeker and provided better performance than it's Grumman competitor the XTBF-1.
Production rights were transferred to Consolidated as the TBY-2 and eventually less than 200 were manufactured before the end of the war caused contract cancellation.
Here are the mockup photos of the XTBU-1 taken on May 4, 1940 showing the design from several different angles. Photos are from NARA II Collection 72AC Box101C.

XTBU-1 Mockup 76 Years Later Part Two
Continuing with the series on the XTBU-1 mockup here are photos of the aircraft in the flight level position, wing folded, from the front and a side view with the cabin enclosure open. Of additional interest is the XF4U mockup with the original tail hook concept sharing the same space in the hangar. NARA II Photos RG 72AC Box101.

XTBU-1 Mockup 76 Years Later Part Three
Continuing on with the series on the XTBU-1 mockup. Here is a series of five photographs that show the turret gun installation. Each of the photos shows the turret in a different position showing it's flexibility and fields of fire for defense of the TBU from upper, rear and side attack, The tunnel gun will be in a further posting. All photos Vought via NARA II RG72.
