Kokusai Ki.105
The Ki-105 Ohtori, ('Phoenix', allied codename Crane) was a project in the last months of the Pacific War. With Allied attacks on ports and shipping, Japan's sources of oil to fuel its defensive fighters were drying up. To meet the demand for aviation fuel, the experimental Kokusai Ku-7 transport glider was developed into a powered version for use in transporting fuel from the oilfields still held in Sumatra to Japan.
This required a range of 2500km, and to achieve this the Ki-105's engines drew on the transported fuel, and used 80% of it to reach Japan (plus what it used to reach Sumatra unloaded). Japan developed a process to make gasoline from pine tree oil, which saw whole forests destroyed to fill the tanks of a few fighter aircraft.
The Ku-7 Manazuru were modified by fitting them with engines, which were designated the Ki-105 Otori ( "Phoenix"). Ku-7-II was the original designation for the Ki-105. Intended for use as fuel transports, only nine, of 300 ordered, were produced before development priorities were shifted elsewhere.
