Ranging from the Middle Ages until World War II, coastal artillery was extremely important in … Such shore-based artillery were used to shell attacking ships as well as invading amphibious forces. "Torpedo" in this case refers to naval mines. On 1 April 1945 the majority of the remaining coast artillery battalions (other than antiaircraft) were inactivated, with most personnel either transferred to their parent harbor defense commands or used to activate or fill out field artillery units. Background- The distinctive unit insignia was approved on 16 October 1929. Three railway mountings for the Chilean 12-inch guns were ready for shipment by the Armistice; the remaining three barrels were retained as spares. Most of the 6-inch guns were stored and were eventually deployed in World War II.. The Coast Artillery soldiers lived in barracks within marching or driving distance of their gun batteries. The officers were trained at the Army’s elite coast artillery school in Fort Monroe, Virginia. There was also a Coast Artillery Reserve of 14 harbor defense regiments, four railway regiments, three tractor-drawn regiments, and 42 anti-aircraft regiments in 8 AA brigades. The new 16-inch and 12-inch batteries of the 1920s were all in open mounts, unprotected against air attack except for camouflage. This page was last edited on 25 December 2020, at 16:56. In order to promote esprit-de-corps, the first seven regiments inherited the lineage of the original seven regiments of artillery. The Japanese were acquiring capital ships with guns of this caliber, beginning with Kongō in 1913. This would mean that the guns on Georges Island could engage enemy ships positioned roughly 12 miles from the State House in downtown Boston. Railway artillery became a permanent part of the CA, but was not widely deployed. The Coast Artillery faced two priorities during the war: mobilization and modernization. , A postwar weapon deployed in more reasonable quantities was the 12-inch gun M1895 on the long-range barbette carriage M1917. With only the anti-aircraft mission left, the Coast Artillery was disestablished and the anti-aircraft and field artillery branches were merged in 1950. CU as gun is loaded. These guns had almost three times the range of the 12-inch DC guns emplaced only 10-15 years earlier. Other than some severed telephone cables, no significant damage to either side occurred.  The 7-inch and 8-inch guns and 12-inch mortars used a common carriage, with outriggers and a rotating mount allowing all-around fire.  Activation of the National Guard and expansion of regular harbor defense regiments to wartime strength resulted in 45,000 troops assigned to this function by fall 1941. The anti-aircraft and field artillery branches were later separated again and regiments eventually re-appeared. All US Army defenses outside the leased baselands were withdrawn from Bermuda on the end of hostilities.. The Coastal Artillery was formed from the Archipelago Artillery, the Marine Regiment and parts of the Artillery in 1902. Four different batteries of coast artillery were located here, including Battery Murphy on East Point (two 16-inch guns), Battery Gardner at Fort. The 16-inch guns of Btty Long on Hog Island were also added during the 1920s, using the Navy guns displaced by naval treaties between the wars, This extended the range of Boston's armament to 25 miles. Prior to the December, 1941, entry of the United States into the Second World War, the United States Army and the United States Marines Corps were permitted to deploy forces to Bermuda under the Destroyers for Bases Agreement, ostensibly to guard US Navy and US Army Air Forces air base sites to which the United States had been granted leases by the British Government, but with the intent of also allowing the neutral US to covertly reinforce the British Army's Bermuda Garrison. In the Utah Beach sector, for instance, 110 guns from 75 to 210 mm were arrayed, capable of destroying landing craft or armored vehicles. One of the three 28 cm main battery guns at Oscarsborg. Circular concrete platforms called "Panama mounts" were added to existing defenses to improve the utility of these guns. , The 16-inch guns were only the top end of the World War II program, which eventually replaced almost all previous coast defense weapons with newer (or remounted) weapons. The attack on Pearl Harbor showed that the Coast Artillery, despite the inclusion of the anti-aircraft mission, was ineffective against a mass air attack. Coastal artillery gun at Fort Columbia State Park.jpg 2,048 × 1,229; 1.83 MB Columbiad 10-inch Model 1840 Side View.jpg 3,221 × 1,837; 3.22 MB Columbiad 10-inch Seacoast Defense Model 1840.jpg 2,063 × … This somewhat inexplicable situation was remedied by casemating most of the newer batteries early in World War II. Most of these were disbanded immediately after the war. Troops run out of underground tunnel to man guns on East Coast. They were, for instance, a decisive factor in the final phase of the Meuse-Argonne Offensive. Battery Torbert (3 guns on M1896 carriages, Fort Delaware, New Castle County, Delaware, installed 1901, deactivated 1940, guns sent to Puerto Rico.) , Mobilization in 1939-41 created more regiments. The CAC also operated heavy and railway artillery during World War I. World War I Lineage. As a result of this reorganization (in most cases), 46 anti-aircraft artillery (AAA) brigades, 155 AAA groups, and 13 coast artillery groups were activated, probably controlling task-organized groups of battalions. A third battery of two 16-inch guns (Construction 105) had been planned for Fort Dawes on Deer Island, and the casemates for these guns were completed. The 8-inch guns and 12-inch mortars were retained on railway mountings after the war, while most of the 10-inch and 12-inch guns were returned to the coastal forts. The anti-aircraft regiments were broken up into battalions in 1943-44 and the harbor defense regiments were similarly broken up in late 1944, as part of an Army-wide reorganization that left only the Infantry branch as regiments.  These were the last guns added to the Philippine defenses until 1940, as the Washington Naval Treaty prohibited additional fortifications in the Pacific.. As with most US Army World War I equipment, these units were primarily equipped with French- and British-made weapons, with few American-made heavy weapons arriving in France before the Armistice. In 1901, the regimental organization of the US Army artillery was abolished, and 126 companies of heavy (coast) artillery and 30 companies of light (field) artillery were established. These units were composed primarily of Filipino enlisted men and US officers, and garrisoned many of the coast defenses in the Philippines until the surrender of US forces there in 1942. The guns of the coast artillery were built to match those carried by the warships of the era. Stark, Major H.

The 40th Artillery Brigade of three regiments was also a railway artillery brigade of the RAR; however, it did not complete training before the Armistice. These assets made Bermuda's defense imperative to the British Empire and Commonwealth's, and later the Allies', global strategy, but British forces used for its defense were desperately needed elsewhere. 82 existing heavy artillery batteries were designated as coast artillery companies, and 44 new CA companies were created by splitting existing units and filling their ranks with recruits. The Performance of Coast Artillery Guns. Shots of coastal artillery gun pointing out to sea on West Coast. All rights reserved. The Coast Artillery would alternate between small unit and regimental organization several times over its history. The 16 inch Gun M1919 (406 mm) was a large coastal artillery piece installed to defend the United States' major seaports between 1920 and 1946. Eight 10-inch railway mounts of 54 ordered were completed by this time, and twelve 12-inch railway mounts were completed by 1 April 1919. Some images may be copyrighted by other authors, as described.  Besides new construction at most harbor defenses, the standard anti-aircraft gun was upgraded from the 3-inch gun M3 to the 90 mm gun M1. 34 of these regiments and 11 brigade headquarters served in France; the remainder stayed in the United States. Although the Coast Artillery did their best, their weapons were poorly positioned against the direction of enemy attacks and vulnerable to air and high-angle artillery attack. By the beginning of World War I, the United States had a coastal defense system that was equal to any other nation. Like the Endicott and Taft period emplacements, they were positioned to be hidden from observation from the sea, but were open to the air. It is a shield of red and blue parted horizontally by a wavy line; on the upper red portion of the shield is the insignia of the Coast Artillery, and on the lower blue portion a submarine mine in gold. The weapon is possibly a German-made 28 cm SK L/40 gun on a coast defense mount. The War Department formed a Board of Review that recommended an increase in strength, which resulted in 105 new CA companies in 1916–17, although these were initially undermanned. The Coast Artillery also had one 8-inch railway gun regiment of 2,040 men, a prewar organization broken up on 1 May 1943.  Also during World War I, the antiaircraft branch was born, with thirteen AA battalions (also called sectors) and six AA machine gun battalions. New coastal artillery guns were installed… New coastal artillery guns were installed on the outlying islands protected Krepost Sveaborg from the sea (of which Kuivasaari was one), while fortified lines were constructed around the landward side of Helsinki and intended to stop any attacks from inland. The 56 th Coast Artillery then became the 58 th Coast Artillery on April 1, 1942 and was sent from California to Venezuela.. Later Battery C, which was my dad’s unit, was sent to Curacao on March 4, 1943 and became the 815 th Coast Artillery, while his buddies in Battery D arrived in Aruba March 11, 1943 were sent to Aruba on March 5, and became the 814 th C.A. Everyone knows that all work and no play is no fun and that’s where Coastal comes in. The heavier K.39/40 coastal version was even longer ranged. 428th Coast Artillery (AA) Regiment (Composite) An initial defense force for Canton Island was formed at Fort Kamehameha, with a detachment of Btry C, 55th CA (TD) Regt, and two 155 mm GPF guns. The guns with Canet gun mounts were usually referred with abbreviation 120/45 C, while those with Lokomo gun mounts were referred as 120/45 CLo. Except for some 6-inch pedestal guns and 3-inch guns, the Endicott- and Taft-period guns were scrapped and the Coast Artillery drawn down in size. The Coast Artillery was designated to provide all US-manned heavy artillery (155 mm gun and larger), railway artillery, and later anti-aircraft artillery units. The table below lists the ranges of the principal guns of the Coast Artillery that defended Boston Harbor between 1898 and 1946. 253rd Coast Artillery (Puerto Rico National Guard), 36th Coast Artillery, Puerto Rico, St. Thomas, later Panama, 58th Coast Artillery, South America, Dutch West Indies, Antiaircraft Artillery Automatic Weapons Battalion, Antiaircraft Artillery Searchlight Battalion.  Seventy-two of the Army 6-inch guns (possibly with a few additional Navy weapons) and 26 5-inch guns also removed from coast defenses were mounted on M1917 field carriages and equipped four artillery regiments in France, but none of these completed training before the Armistice. The Japanese initially landed in northern Luzon, far from the defenses of Manila Bay. However, as the war's progress greatly reduced the threat from enemy surface vessels, only 21 of these were completed, and not all of them were armed. Prior to 1901 each of the seven artillery regiments contained both heavy and light artillery batteries. The 16-inch guns were one 16-inch gun M1895 on a disappearing carriage, seven 16-inch M1919 guns (one on a disappearing carriage), four 16-inch M1920 howitzers, and ten 16"/50 caliber Mark 2 guns (including some Mark 3 guns), the last taken from weapons produced for South Dakota-class battleships and Lexington-class battlecruisers cancelled by the Washington Naval Treaty. There was also Royal Air Force Bermuda on Darrell's Island which was vital to trans-Atlantic aviation, a Fleet Air Arm air station on Boaz Island, cable and radio facilities important to trans-Atlantic navigation and communication, and other strategic assets (which would be joined by the US Army air base, the US Naval Operating Base (for flying boats and ships), a US Navy submarine base on Ordnance Island, and a Royal Canadian Navy base). In 1905, after the experiences of the Spanish–American War, President Theodore Roosevelt appointed a new board on fortifications, under Secretary of War William Howard Taft. The anti-aircraft mission continued with three battalions in the Contiguous United States (CONUS), one battalion in the Philippines, and a regiment in Hawaii.. Except for the early-war fighting in the Philippines, the anti-aircraft branch was the Coast Artillery's only contribution on the front lines of World War II; almost all mobile heavy artillery overseas was operated by the Field Artillery. In 1922 fifteen companies of Philippine Scouts coast artillery were established. In 1944, with about 2/3 of the initially projected new batteries complete and most naval threats neutralized or destroyed, work was stopped on the remaining new batteries. Permission is hereby given for limited reuse of images and accounts for non-commercial purposes. The Office of the Chief of Coast Artillery was established in the rank of major general 1 July 1908 until it was abolished 9 March 1942, with functions transferred to the Commanding General, Army Ground Forces, effective 9 March 1942, by Circular 59, War Department, 2 March 1942. Most of the reserve regiments not designated as anti-aircraft in 1925 appear to have been disbanded by World War II. Coastal artillery used many of the same weapons mounted in casemates, usually manned by army units under navy control. , By the end of the 1920s eight Harbor Defense Commands in less-threatened areas were completely disarmed. Bermuda had been the headquarters and main base of the Royal Navy's North America and West Indies Squadron since the independence of the United States, and the location of its dockyard. Supporters- Two cannons, muzzles up, are used as supporters. This board recommended a large-scale program of harbor defenses at 29 ports, including guns, mortars, and mine fields. The modern era seacoast guns were emplaced in protected concrete structures and were generally more accurate than those carried on the warships, the seacoast artillery could cause more damage to the ships than they could inflict on the defenses. These were the same guns found in Endicott period installations, but on a high-angle carriage that increased their range from 18,400 yd (16,800 m) on a disappearing carriage at 15° elevation to 29,300 yd (26,800 m) at 35° elevation. The Japanese invasion of the Philippines resulted in the surrender of US forces there on 9 April and 6 May 1942, including the 59th CA (HD), 60th CA (AA), 200th CA (AA), 515th CA (AA), 91st CA (HD) (PS), and 92nd CA (TD) (PS).  The coast defense commands retained a company-based organization. The 16-inch gun (like the one on a barbette carriage pictured at right at Aberdeen Proving Grounds, Aberdeen, Maryland), mounted on the M1919 carriage was the standard major caliber weapon of the Coast Artillery after WW I, although some 12-inch guns were still being emplaced. Selected batteries of older 3-inch guns were retained throughout WW2. The CDSG is a non-profit corporation formed to promote the study of coast defenses and fortifications, primarily those of the United States of America; their history, architecture, technology, and strategic and tactical employment. In 1907 the Coast Artillery Corps was established and the Field Artillery re-regimented.  On 9 June 1925 the Coast Defense Commands were redesignated as Harbor Defense Commands via a War Department order.  Over 900 battalions were created with the following designations:. , Army leaders realized that heavy fixed artillery required different training programs and tactics than mobile field artillery. The men in the coastal batteries of Oscarsborg Fortress had other ideas. Twelve 7-inch ex-Navy guns and six 12-inch guns being built for Chile were also available. Almost all of the National Guard units above were mobilized during this period.  In 1907 the United States Army Field Artillery School at Fort Monroe became the Coast Artillery School, which operated until 1946, and in 1908, the Chief of Artillery became the Chief of Coast Artillery in the rank of major general. By 1943, however, it had became clear that no country would be able to mount a credible naval threat against the United States, so this third 16-inch battery was cancelled before its gun tubes had been delivered. The company-based organization was for flexibility, as each harbor defense command was differently equipped and a task-based organization was needed. Shield- Per fess wavy Gules and Azure in chief on an oval escutcheon of the first (Gules) in front of the cannon saltirewise Or an Artillery projectile paleways within a bordure of the last (Or) in base a submarine mine of the like (Or). Firearms. The subsections of this section provide descriptions and images of those Coast Artillery guns and mortars that were used in Maine, Massachusetts, and New Hampshire during the period from 1898 to 1946. After the American entry into World War I, the Coast Artillery as a whole was ordered brought up to strength, and 71 new companies were organized by July 1917.. The rapidity of technological advances and changing techniques increasingly separated coastal defenses (heavy) from field artillery (light). The design was used by the Coast Artillery School for many years but was never recorded by the War Department. None of the army weapons were shipped to France except three 8-inch guns and some 10-inch barrels (to be mounted in France), as few of any type were completed before the Armistice. The remaining 50 or so weapons were retained by the Navy for use on future battleships; but in 1940 a near-fiasco in the design of the Iowa-class battleships precluded their use on that class, and the guns were released to the Army. As the table shows, this gave the harbor defenses an outer reach of some 7 to 8 miles.

As the defenses were constructed, each harbor or river's installations were controlled by Artillery Districts, renamed Coast Defense Commands in 1913 and Harbor Defense Commands in 1925. Subunits included "B" Battery, 57th Regiment, United States Army Coast Artillery Corps, deployed to Ackermann's Hill at Warwick Camp in 1941 with two 155mm GPF artillery guns on wheeled carriages, which were placed on "Panama mounts" by October 1941. Implementation of the Act by the Army was published in War Department Bulletin 43, dated 22 July 1918. Most of their recommendations were implemented and new defenses were constructed by the United States Army Corps of Engineers 1895–1905. In Boston, for example, harbor defense in the Endicott-Taft Period (1895-1915) was provided principally by 10-inch and 12-inch rifles on disappearing carriages (DC) in the harbor forts, supported by many batteries of 3-inch rapid fire (RF) guns. Many considered the duty a privilege because it was close to the social life of San Francisco. Officers were rarely qualified to command both, requiring specialization. With a view to getting numerous US-made weapons into the fight eventually, the Army also converted some of the many US coast artillery weapons to railway mounts. As with other American World War I units, the CAC units operated alongside French forces for the most part. If we take average range as 7.5 miles, this would be roughly the distance between Battery Stevenson at Fort Warren (the 12-inch guns on Georges Island) northerly to East Point in Nahant or southeasterly to the coast in Hingham just below the base of the Hull peninsula. Confusingly, many of these units were designated Coast Artillery Corps of their respective state National Guards. As a result, in 1907, Congress split the Field Artillery and Coast Artillery into separate branches, creating a separate Coast Artillery Corps (CAC), and authorizing an increase in the Coast Artillery Corps to 170 numbered companies. 100-мм береговая пушка КСМ-65 в Бербере.jpg 918 × 611; 171 KB. The four regiments of the 30th Railway Artillery Brigade initially remained, along with six tractor-drawn regiments equipped with the 155 mm gun M1918 (6.1 inch), developed from the French Canon de 155mm GPF (Grand Puissance Filloux, or high-powered gun designed by Filloux), a weapon these regiments used during the war. No US railway guns existed when the US entered World War I in early 1917. In 1943–44, with most of the new defenses completed, the numerous older weapons of the Endicott and Taft periods were scrapped, with their crews largely reassigned to field artillery units.. In addition, after decades of experimentation and development, largely stymied by inadequate funding, the coast artillery adopted gun data computers, primarily for the last generation of batteries. List of coastal artillery. The lineage of the 251st Coast Artillery Regiment (Anti-Aircraft) of the California National Guard traces all the way back to parent units organized on September 16th, 1916 as companies of the 1st Coast Defense Command of the Coast Artillery … The Japanese invaded the Philippines shortly after Pearl Harbor, bringing the Harbor Defenses of Manila and Subic Bays into the war along with the other US and Filipino forces in the archipelago.
