HMS Hesperus was an H-class destroyer that had originally been ordered by the Brazilian Navy with the name Juruena in the late 1930s, but was bought by the Royal Navy after the beginning of World War II in September 1939, commissioned in 1940 as HMS Hearty though quickly renamed.
The Atlanta-class cruisers were eight United States Navy light cruisers designed as fast scout cruisers or flotilla leaders but that proved to be effective anti-aircraft cruisers during World War II. They were also known as the Atlanta-Oakland class. The four Oakland and later ships had slightly different armament as they were further optimized for anti-aircraft fire. The Atlanta class had 12 x 5-inch (127 mm)/38 caliber guns, mounted in three superfiring sets of two-gun turrets fore and three more aft. The first four ships of the class also had an additional two twin 5-inch/38 mounts, one port and one starboard, giving these first four Atlanta-class cruisers the heaviest anti-aircraft armament of any cruiser of World War II.
The BL 7.2-inch howitzer was a heavy artillery piece used by the British Army throughout the Second World War.
The QF 3.7-inch AA was Britain's primary heavy anti-aircraft gun during World War II. It was roughly the equivalent of the German 88 mm FlaK and American 90 mm, but with a slightly larger calibre of 3.7 inches, approximately 94 mm. Production began in 1937 and it was used throughout World War II in all theatres except the Eastern Front. It remained in use after the war until AA guns were replaced by guided missiles beginning in 1957.
The QF 5.25-inch Mark I gun was the heaviest dual-purpose gun used by the Royal Navy during the Second World War. Although considered less than completely successful, it saw extensive service. 267 guns were built.
Parson's Lodge Battery is a coastal battery and fort in the British Overseas Territory of Gibraltar.
Princess Anne's Battery is an artillery battery in the British Overseas Territory of Gibraltar. It is located on Willis's Plateau at the northern end of the Upper Rock Nature Reserve, above Princess Caroline's Battery. It was named after Anne, Princess Royal and Princess of Orange, the eldest daughter of George II. However, its name is often confused with those of other batteries in the area. In 1732, guns were first mounted on the battery, which also saw action during the Great Siege of Gibraltar. Princess Anne's Battery was updated in the nineteenth and twentieth centuries, with the latter modernisation entailing the installation of four QF 5.25 inch guns with both anti-aircraft and coastal defence capabilities. The battery was manned into the early 1980s, after which it was decommissioned. The guns were refurbished in the early twenty-first century, and represent the world's only intact battery of 5.25 inch anti-aircraft guns. Princess Anne's Battery is listed with the Gibraltar Heritage Trust.
Rock Gun Battery is an artillery battery in the British Overseas Territory of Gibraltar. It is located on the North Face of the Rock of Gibraltar at the northern end of the Upper Rock Nature Reserve, above Green's Lodge Battery. The emplacement on Middle Hill is at the northern summit of the Rock. It was constructed during the Great Siege of Gibraltar, due to its advantageous position and the success of the gun at Green's Lodge Battery. It was used effectively during the Great Siege and was rebuilt during the Second World War. During the mid-twentieth century, the Ministry of Defence began to use the site as an aerial farm, which was then refurbished in 1958. The Rock Gun Battery and the Middle Hill Battery were closed to the public for decades. In 2005, the radio farm was closed and the Ministry of Defence withdrew from most of the area, transferring it to the Government of Gibraltar. However, the summit, the site of the Rock Gun Battery, continues to be under MOD authority.
Middle Hill Battery is an artillery battery in the British Overseas Territory of Gibraltar. It is located on Middle Hill, at the northeastern end of the Upper Rock Nature Reserve, just south of Green's Lodge Battery and Rock Gun Battery. The emplacement dates to 1727, when a single gun was mounted. By the turn of the twentieth century, six 10-inch rifled muzzle-loading guns were present at Middle Hill Battery. Other buildings documented at that time as part of the battery complex included the Nursery Hut and the Middle Hill Group, the latter a cluster of buildings which perched on the cliff edge. An anti-aircraft Bofors gun had been installed at the battery by the Second World War. After the war, the area transitioned to use as a Ministry of Defence aerial farm. In 2005, the battery and surrounding area were transferred to the Government of Gibraltar. The site is now managed by the Gibraltar Ornithological and Natural History Society.
