Hardly the USAAC's last biplane - Boeing-Stearman PT-17s were still being delivered in 1945! But it WAS the last USAAC biplane fighter. (I know that for some, only the fighters count - lol).

Here's the article in Vol 48:
"
THE CURTISS TWIN-ENGINED TORPEDO SEAPLANE . - The Curtiss Aeroplane & Motor Corporation of Garden City, L. I., has recently turned over to the Navy Department a very interesting torpedo seaplane known as the Curtiss CT (Curtiss Torpedoplane). This is one of the most advanced designs yet produced in the country and shows that American military airplane design is able to keep pace with that of any other country in the world; in fact this machine would appear to be without a rival as far as excellence of design is concerned. The machine is a cantilever monoplane with the engine mounted practically in the wings. The engines are Curtiss CD12's and drive tractor propellers. The cooling is by two Lamblin radiators mounted under the engine nacelles under the wing. The fuel tanks are in the wings between the engine nacelles and the central nacelle. The engine instruments are mounted on the side of the nacelle in plain view of the pilot; in fact they are only about 3 feet from his head and on a level with it. The entire machine, except for the wing covering, is built of wood. The wings are covered with fabric and taper both in chord and camber from the root to the tip. They have a span of 65 feet. The maximum thickness of the wings is 30 inches and the chord at the root 16 feet, which gives a maximum wing depth of 15.6 per cent. It is expected that future models will be constructed of metal and will be somewhat lighter. The undercarriage consists of two floats, one under each engine. This arrangement obviates the need of wing tip floats and the main floats are sufficiently long to allow the designer to dispense with any tail floats also. The empennage is supported on booms, one of a pair running from the rear end of the float and the other from the rear of the engine nacelle, the pairs being parallel. There are four booms altogether. There are two vertical fins and two balanced rudders. The method of rudder control is very interesting. There is only one control horn on each rudder; these horns are in the space between the rudders. The tips of the balanced portions are connected together by a wire. Thus a pull on one control horn is transmitted through the rudder to the balance wire and by that means to the other rudder. The rudders are located directly behind the propellers and hence are in the slipstream, which arrangement makes for excellent control. This machine has a high speed of 112 m.p.h. With only one engine running it loses only about 100 feet per minute. It is expected that with metal construction the machine will be able to fly level on one engine. The useful load is about 3,800 pounds consisting of fuel and oil, crew, and a standard torpedo or bomb load. The crew consists of a gunner, pilot, and assistant pilot. The pilot also acts as the bomber. There are several very ingenious gadgets on this machine. Among these may be mentioned the stands for the mechanics to work on the engines from. These are shelves that pull in and out of the wing on each side of the engines. Handgrips on the sides of the central nacelle and steps on the undercarriage struts provide easy access and exit . -Aviation, 6 February, 1922.
There are also a couple of later mentions in later months of Vol 48. "The Curtiss Aeroplane and Motor Corp. constructed a plane known as the CT - a biplane having twin 400 hp. engines. The CT has recently been subjected to trials and tests at Rockaway, L. I., and will not be tested further for the present at Anacostia." Also: "Among naval aircraft there have been developed the Curtiss torpedo dropper - a notable departure in seaplane construction. Great promise is also shown by the Douglass (sic) torpedo dropper."

A new model to my eyes the LWF H (laminated Wood Fuselage) Whats not to like, 3 Liberty Engines, Smooth streamlined booms and center nacelle, 6 main wheel, and enough Struts and wires t cancel out all the careful streamlining of the nacelle's.

Is that a racing pylon in the rear?

This aircraft started out as a MB-1 (top picture) and was changed from a twin engine bomber into a trimotor single seat at Mc Cook field 1921

Ed that is what I was thinking also, probably would make the location as Cleveland if it is an air racing pylon. At 1st I thought it read "Bend" but it probably reads Bendix. But I guess it could also be the starting point at Burbank California. But I would place my $$$'s on Cleveland.
