context_page_description: Coastal artillery is the branch of the armed forces concerned with operating anti-ship artillery or fixed gun batteries in coastal fortifications.
  From the Middle Ages until World War II, coastal artillery and naval artillery in the form of cannon were highly important to military affairs and generally represented the areas of highest technology and capital cost among materiel. The advent of 20th-century technologies, especially military aviation, naval aviation, jet aircraft, and guided missiles, reduced the primacy of cannon, battleships, and coastal artillery. In countries where coastal artillery has not been disbanded, these forces have acquired amphibious capabilities. In littoral warfare, mobile coastal artillery armed with surface-to-surface missiles still can be used to deny the use of sea lanes.
  It was long held as a rule of thumb that one shore-based gun equaled three naval guns of the same caliber, due to the steadiness of the coastal gun which allowed for significantly higher accuracy than their sea-mounted counterparts. Land-based guns also benefited in most cases from the additional protection of walls or earth mounds.
context_section_description: Nazi Germany fortified its conquered territories with the Atlantic Wall. Organization Todt built a string of reinforced concrete pillboxes and bunkers along the beaches, or sometimes slightly inland, to house machine guns, antitank guns, and artillery ranging in size up to the large 40.6 cm naval guns. The intent was to destroy Allied landing craft before they could unload. During the Normandy Landings in 1944, shore bombardment was given a high importance, using ships from battleships to destroyers and landing craft. For example, the Canadians at Juno beach had fire support many times greater than they had had for the Dieppe Raid in 1942.
  The old battleships HMS Ramillies and Warspite with the monitor HMS Roberts were used to suppress shore batteries east of the Orne; cruisers targeted shore batteries at Ver-sur-Mer and Moulineaux; while eleven destroyers provided local fire support.  The (equally old) battleship Texas was used to suppress the battery at Pointe du Hoc, but the guns there had been moved to an inland position, unbeknownst to the Allies. In addition, there were modified landing craft: eight "Landing Craft Gun", each with two 4.7-inch guns; four "Landing Craft Support" with automatic cannon; eight Landing Craft Tank (Rocket), each with a single salvo of 1,100 5-inch rockets; eight Landing Craft Assault (Hedgerow), each with twenty-four bombs intended to detonate beach mines prematurely. Twenty-four Landing Craft Tank carried Priest self-propelled 105mm howitzers which also fired while they were on the run-in to the beach. Similar arrangements existed at other beaches.
  On June 25, 1944 the American battleship Texas engaged German shore batteries on the Cotentin Peninsula around Cherbourg. Battery Hamburg straddled the ship with a salvo of 240mm shells, eventually hitting Texas twice; one shell damaging the conning tower and navigation bridge, with the other penetrating below decks but failing to explode. Return fire from Texas knocked out the German battery.
  Allied efforts to take the port of Toulon in August 1944 ran into "Big Willie", a battery consisting of two prewar French turrets, equipped with the guns taken from the French battleship Provence, each mounting a pair of 340 mm naval guns. The range and power of these guns was such that the Allies dedicated a battleship or heavy cruiser to shelling the fort every day, with the battleship Nevada eventually silencing the guns on August 23, 1944.
