Battery Gunnison, later called Battery New Peck, is a six inch coast artillery battery located on Sandy Hook in New Jersey. Gunnison was built in 1903 as a twin six inch disappearing gun battery. In 1942 the battery was altered to accept two M1900 six inch pedestal mounted guns along with the addition of two shell hoists and a plotting room. The battery was renamed Battery New Peck after the modification because the two six inch guns were transferred from Battery Peck. Battery Peck was named in honor of an artillery officer who was killed in the Sandy Hook proving ground. Battery New Peck was in use until 1949.
