Nuclear Assault is an American thrash metal band formed in New York City in 1984.
After the release of Anthrax’s debut album Fistful of Metal, bassist Dan Lilker, a founding member of the group, was fired by the band. He decided to pursue a more aggressive style of music and formed Nuclear Assault. Nuclear Assault released five albums and toured relentlessly throughout the 80s and early 90s, and broke up in 1995. The band reunited briefly in 1997 and then permanently in 2002.
