Major applicationsCurtiss Model R
Developed intoCurtiss V-2

The Curtiss V is a 160 hp (120 kW) water-cooled V-8 aero-engine. A nearly identical engine rated for 180 hp (130 kW) was marketed as the V-X.[1]: 149 

The engine was produced at Curtiss's Hammondsport and Buffalo facilities from 1915 to power the Curtiss R-series biplane trainers.[2]. Curtiss continued development of the "V" series eventually producing the 200 hp (150 kW) Curtiss V-2.

With the onset of World War I, Curtiss shifted its focus to the 67 kW (90 hp) Curtiss OX-5, which became the primary powerplant for the Curtiss JN Jenny trainer aircraft. The introduction of the government’s Liberty L-12 engine addressed the demand for higher power, leading to the discontinuation of the V series before it reached mass production.[2]
