uranium-235 (U-235), radioactive isotope of the element uranium with a nucleus containing 92 protons and 143 neutrons. Uranium-235 is the only naturally occurring fissile material; that is, the uranium-235 nucleus undergoes nuclear fission when it collides with a slow neutron (a neutron with a kinetic energy less than 1 electron volt). Uranium-235 constitutes about 0.72 percent of all naturally occurring uranium. (Most naturally occurring uranium is uranium-238.) It has a half-life of 704 million years, decaying to thorium-231, with the radioactive decay chain eventually ending in the stable isotope lead-207. Uranium-235 must be separated from the more plentiful isotope uranium-238

The Dornier Do 335 Pfeil ("Arrow") was a Nazi Germany World War II heavy fighter built by the Dornier company. The two-seater trainer version was called Ameisenbär ("anteater").

It was Nazi Germany's fastest piston-engined aircraft of World War II.
