New Needles Battery was built on the hill (390 feet) immediately to the rear of the Old Needles Battery. Built between 20th October, 1893 and 25th May, 1895 with three 9.2-inch Mark IX barbette emplacement, but only two guns were mounted by 1900. The cost of construction was some £9,821. The third gun was installed by 1904 giving three 9.2-inch guns on Mark III Barbette mounts.
A pair of 3-pdr Q.F. guns were mounted between the middle and Northern emplacements as a practice battery in about 1904 but were removed within a few years.
Between 1900 and 1902 a large Battery Command Post (BCP) was built above and behind the battery at this still stands, although probably modified in World War 2. This was in addition to the Fort Commander’s Station on the right hand side of the ‘A’ gun emplacement.
Accommodation buildings were built into the hillside behind the gun emplacements. Before the outbreak of World War I a Port War Signal Station (PWSS) was built to the East of the Battery. Between 1911 and 1914 the emplacements were adapted to take Mark VI mountings for the 9.2-inch guns. About this time a further 6-pdr Q.F, gun was mounted to the South of the left (‘C’) gun emplacement to cover the Examination Anchorage.
During World War II the battery was active but stood down in 1945 before being decommissioned in 1952. The nearby site was used for testing the Black Arrow and Black Knight space rockets between 1956 and 1971. A coast guard station was built in the South (‘c’) gun emplacement and is till in use (2025).
