Atomic bombings of Hiroshima and Nagasaki
Development began in 1987 and developmental testing of the warhead ended in 1991, but French president Jacques Chirac asserted in June 1995 (50 years after the Atomic bombings of Hiroshima and Nagasaki) that a full yield proof test was needed prior to deployment, causing an international outcry. Its first full-yield test was probably the 110 kt detonation on 1 October 1995 at Fangataufa.
