Nuclear Assault was an American thrash metal band formed in New York City in 1984. Part of the mid-to-late 1980s thrash metal movement, they were one of the main bands of the genre to emerge from the East Coast along with Overkill, Whiplash, Toxik, Carnivore, and Anthrax, the last of which was co-founded by Nuclear Assault bassist Dan Lilker, who left Anthrax shortly after the release of their first album. Nuclear Assault released five full-length albums and toured relentlessly throughout the 1980s and early 1990s, and broke up in 1995. The band reunited briefly in 1997, 2002, 2005 and 2015 before breaking up for the fourth time in 2022.
