Curtiss 18
Template:Short description Template:Infobox aircraft
The Curtiss 18T, unofficially known as the Wasp and by the United States Navy as the Kirkham,[1] was an early American triplane fighter aircraft designed by Curtiss for the US Navy. It was redesignated Curtiss Model 15 in Curtiss's later rationalization of their model numbering.[2]
Design and development
The Curtiss 18T was intended to protect bombing aircraft over France, and a primary requisite for this job was speed. Speed was not the triplane's only salient feature: an 18T-2 set a new altitude record in 1919 of Template:Cvt.[3] The streamlined and very "clean" fuselage contributed to the aircraft's performance. The basic construction was based on cross-laminated strips of wood veneer formed on a mold and attached to the inner structure. The technique was a refinement of that used on the big Curtiss flying boats.[4]
Operational history
Flown by Roland Rholfs, the 18T achieved a world speed record of Template:Cvt in August 1918 carrying a full military load of Template:Cvt.[5]
The Model 18T-2 was an improved version of its predecessor, with 50 additional horsepower. The wings of the new model were swept back. It was also Template:Cvt longer with a Template:Cvt larger two-bay wing, though its operational ceiling was Template:Cvt lower.
After World War I, it was employed as a racing plane: an 18T-2 nearly won the Curtiss Marine Trophy Race in 1922 (limited to U.S. Navy pilots), but the pilot, Lt. Sanderson ran out of fuel just before the finish line.[6]
Curtiss Engineering followed the Model 18T with the Model 18B, unofficially known as the "Hornet", built to otherwise similar specifications.

Variants
- Model 18T or 18T-1
- Two-seat fighter triplane with single-bay wings, powered by a Template:Cvt Curtiss K-12 piston engine. Referred to by the US Navy as the "Kirkham". Originally designated 18T, the type was redesignated the 18T-1 when the prototype was modified to a new configuration designated 18T-2 (see below).
- Model 18T-2
- 18T with longer-span two-bay wings. Could be fitted with floatplane or landplane landing gear.
- Model 18B
- Biplane fighter version, known unofficially as the "Hornet". Sole flying prototype of Curtiss 18B, USAAS 40058, 'P-86', crashed early in flight trials at McCook Field, Dayton, Ohio, summer 1919. Type not ordered into production. One non-flying prototype also delivered for static testing.[7] Redesignated Model 15A[2]
