The B6N Tenzan ("Mountain of the Sky") was an excellent replacement for the Nakajima B5N "Kate" in its role as a carrier-based torpedo plane. Known as "Jill" in the Allied codename system, the large single engine plane appeared with its first prototype in the spring of 1941, before Japan went to war with the Western powers. After enduring a number of teething problems and redesign issues a total of 133 of the first version, the B6N1, were built. Late in 1943 a second production model, the B6N2, appeared. A total of 1,268 B6Ns were built.
