Gun-howitzer (also referred to as gun howitzer) is a type of artillery weapon that is intended to fulfill the roles of both an ordinary cannon or field gun, and of a howitzer. [1] It is thus able to convey both direct and indirect fire. [1] Modern gun-howitzers are usually identified just as howitzers.
To be able to serve as a howitzer, gun-howitzers are typically built to achieve at least 60° to 70° of elevation. For effective direct fire, the gun-howitzers typically employ a fairly long gun barrel, usually not shorter than 30 calibres. Also, its ammunition has a high muzzle velocity and is usually of large calibre (120 millimetres (4.72 in) or greater). [1]
Historically the first gun-howitzer was the French canon obusier of the mid-19th century. The smooth-bore Canon obusier de 12 was a versatile weapon that quickly replaced both ordinary cannons and howitzers in French service, and became one of the basic types of artillery used by both sides of the American Civil War. [2] Owing to their versality, gun-howitzers gained prominence in the period leading to World War II as a more flexible weapon than ordinary howitzers and were adopted by armies of both the Allies (for instance the Soviet ML-20 152 mm M1937 and British (88 mm) Ordnance QF 25-pounder) and the Axis (German 10.5 cm leFH 18, classified just as howitzer). [3]
A modern example of gun-howitzer is M-84 NORA.
After World War II, barrel length of howitzer designs started to grow gradually in order to obtain longer range, and as a result, separate category of gun-howitzer merged with howitzers and cannons. [4] In modern armies gun-howitzers are usually identified just as howitzers. [4]
The howitzer is an artillery weapon that falls between a cannon and a mortar. It is generally aimed lower than a mortar but higher than a cannon. With their long-range capabilities, howitzers can be used to great effect in a battery formation with other artillery pieces, such as long-barreled guns, mortars, and rocket artillery.
In military organizations, an artillery battery is a unit or multiple systems of artillery, mortar systems, rocket artillery, multiple rocket launchers, surface-to-surface missiles, ballistic missiles, cruise missiles, etc., so grouped to facilitate better battlefield communication and command and control, as well as to provide dispersion for its constituent gunnery crews and their systems. The term is also used in a naval context to describe groups of guns on warships.
Field artillery in the American Civil War refers to the artillery weapons, equipment, and practices used by the Artillery branch to support the infantry and cavalry forces in the field. It does not include siege artillery, use of artillery in fixed fortifications, or coastal or naval artillery. Nor does it include smaller, specialized artillery classified as small arms.
Licorne is the French name of an 18th- and 19th-century Russian cannon, a type of muzzle-loading howitzer, devised in 1757 by M.W. Danilov and S.A. Martynov and accepted by artillery commander, general Peter Ivanovich Shuvalov.
The twelve-pound cannon is a cannon that fires twelve-pound projectiles from its barrel, as well as grapeshot, chain shot, shrapnel, and later shells and canister shot. It was first used during the Tudor period and was commonly used during the Napoleonic Wars, 1799–1815. At this time 12-pounders were the largest caliber of long-barreled field pieces, and were used both at long range against fortifications and troop concentrations using round shot and against attacking infantry and cavalry using canister shot. As such the 12-pounder was a favorite weapon of the Grande Armée. Later, redesigned 12-pounders were named after Napoleon III and found heavy use during the American Civil War.
The Canon obusier de 12, also known as the "Canon de l’Empereur", was a type of canon-obusier developed by France in 1853. Its performance and versatility allowed it to replace all the previous field guns, especially the Canon de 8 and the Canon de 12 as well as the two howitzers of the Valée system.
James rifle is a generic term to describe any artillery gun rifled to the James pattern for use in the American Civil War, as used in some period documentation. Charles T. James developed a rifled projectile and rifling system. Modern authorities such as Warren Ripley and James Hazlett have suggested that the term "James rifle" only properly applies to 3.8 in (97 mm) bore field artillery pieces rifled to fire James' projectiles. They contend that the term does not apply to smoothbores that were later rifled to take the James projectiles in 3.67 in (93 mm) caliber or other calibers, and that those should instead be referred to as "Rifled 6 pounder", etc. The rifle was created in 1861.
The 3-inch ordnance rifle, model 1861 was a wrought iron muzzleloading rifled cannon that was adopted by the United States Army in 1861 and widely used in field artillery units during the American Civil War. It fired a 9.5 lb (4.3 kg) projectile to a distance of 1,830 yd (1,670 m) at an elevation of 5°. The 3-inch rifle was not as effective in firing canister shot as the heavier 12-pounder Napoleon, but it proved to be highly accurate at longer ranges when firing common shell or spherical case shot. There was only one reported case of a 3-inch ordnance rifle bursting in action. This was in stark contrast to the similarly-sized cast iron 10-pounder Parrott rifles which occasionally burst without warning, inflicting injury on the gun crews. The Confederate States of America lacked the technology to manufacture reliable copies of the 3-inch ordnance rifle. However, the Confederate States Army respected the weapons and employed those captured from Federal forces.
The Obusier de 400 Modèle 1915/1916 were French railway howitzers that saw action during the First World War and World War II. The mle 1915/1916 was the largest caliber railway howitzers in service with the French Army during the First World War.
The Obusier de 120 mm C modèle 1890 - was a French howitzer designed by Captain Louis Henry Auguste Baquet and employed by the French army during the First World War. It was one of the first modern howitzers equipped with a recoil system.
The Obusier de 155 mm C modèle 1881 - was a French howitzer designed by Colonel Charles Ragon de Bange and employed by the French army during the First World War.
The Obusier de 155 mm C modèle 1890 - was a French howitzer designed by Captain Louis Henry Auguste Baquet and employed by the French army during the First World War. It was one of the first modern howitzers equipped with a recoil system.
The M1841 6-pounder field gun was a bronze smoothbore muzzleloading cannon that was adopted by the United States Army in 1841 and used from the Mexican–American War to the American Civil War. It fired a 6.1 lb (2.8 kg) round shot up to a distance of 1,523 yd (1,393 m) at 5° elevation. It could also fire canister shot and spherical case shot (shrapnel). The cannon proved very effective when employed by light artillery units during the Mexican–American War. The cannon was used during the early years of the American Civil War, but it was soon outclassed by newer field guns such as the M1857 12-pounder Napoleon. In the U.S. Army, the 6-pounders were replaced as soon as more modern weapons became available and none were manufactured after 1862. However, the Confederate States Army continued to use the cannon for a longer period because the lesser industrial capacity of the South could not produce new guns as fast as the North.
The M1841 12-pounder field howitzer was a bronze smoothbore muzzle-loading artillery piece that was adopted by the United States Army in 1841 and employed during the Mexican–American War and the American Civil War. It fired a 8.9 lb (4.0 kg) shell up to a distance of 1,072 yd (980 m) at 5° elevation. It could also fire canister shot and spherical case shot. The howitzer proved effective when employed by light artillery units during the Mexican–American War. The howitzer was used throughout the American Civil War, but it was outclassed by the 12-pounder Napoleon which combined the functions of both field gun and howitzer. In the U.S. Army, the 12-pounder howitzers were replaced as soon as more modern weapons became available. Though none were manufactured after 1862, the weapon was not officially discarded by the U.S. Army until 1868. The Confederate States of America also manufactured and employed the howitzer during the American Civil War.
The 10-pounder Parrott rifle, Model 1861 was a muzzle-loading rifled cannon made of cast iron that was adopted by the United States Army in 1861 and often used in field artillery units during the American Civil War. Like other Parrott rifles, the gun breech was reinforced by a distinctive band made of wrought iron. The 10-pounder Parrott rifle was capable of firing shell, shrapnel shell, canister shot, or solid shot. Midway through the war, the Federal government discontinued the 2.9 in (74 mm) version in favor of a 3.0 in (76 mm) version. Despite the reinforcing band, the guns occasionally burst without warning, which endangered the gun crews. The Confederate States of America manufactured a number of successful copies of the gun.
The 20-pounder Parrott rifle, Model 1861 was a cast iron muzzle-loading rifled cannon that was adopted by the United States Army in 1861 and employed in field artillery units during the American Civil War. As with other Parrott rifles, the gun breech was reinforced by a distinctive wrought iron reinforcing band. The gun fired a 20 lb (9.1 kg) projectile to a distance of 1,900 yd (1,737 m) at an elevation of 5°. The 20-pounder Parrott rifle could fire shell, shrapnel shell, canister shot, and more rarely solid shot. In spite of the reinforcing band, the 20-pounder earned a dubious reputation for bursting without warning, killing or injuring gunners. The Confederate States of America also manufactured copies of the gun.
The 14-pounder James rifle or James rifled 6-pounder or 3.8-inch James rifle was a bronze muzzle-loading rifled cannon that was employed by the United States Army and the Confederate States Army during the American Civil War. It fired a 14 lb (6.4 kg) solid shot up to a distance of 1,530 yd (1,400 m) at 5° elevation. It could also fire canister shot and common shell. Shortly before the war broke out, the U.S. Army adopted a plan to convert M1841 6-pounder field guns from smoothbore to rifled artillery. Rifling the existing 6-pounders would both improve the gun's accuracy and increase the weight of the shell. There were two major types produced, both were bronze with a bore (caliber) of 3.8 in (97 mm) that would accommodate ammunition designed by Charles Tillinghast James. The first type looked exactly like an M1841 6-pounder field gun. The second type had a longer tube with a smooth exterior profile similar to a 3-inch Ordnance rifle. At first the rifles were quite accurate. However, it was discovered that the bronze rifling quickly wore out and accuracy declined. None of the rifles were manufactured after 1862, and many were withdrawn from service, though some artillery units employed the guns until the end of the war.
The M1841 24-pounder howitzer was a bronze smoothbore muzzle-loading artillery piece adopted by the United States Army in 1841 and employed from the Mexican–American War through the American Civil War. It fired a 18.4 lb (8.3 kg) shell to a distance of 1,322 yd (1,209 m) at 5° elevation. It could also fire canister shot and spherical case shot. The howitzer was designed to be employed in a mixed battery with 12-pounder field guns. By the time of the American Civil War, the 24-pounder howitzer was superseded by the 12-pounder Napoleon, which combined the functions of both field gun and howitzer. The 24-pounder howitzer's use as field artillery was limited during the conflict and production of the weapon in the North ended in 1863. The Confederate States of America manufactured a few 24-pounder howitzers and imported others from the Austrian Empire.
The M1857 12-pounder Napoleon or Light 12-pounder gun or 12-pounder gun-howitzer was a bronze smoothbore muzzle-loading artillery piece that was adopted by the United States Army in 1857 and extensively employed in the American Civil War. The gun was the American-manufactured version of the French canon obusier de 12 which combined the functions of both field gun and howitzer. The weapon proved to be simple to produce, reliable, and robust. It fired a 12.03 lb (5.5 kg) round shot a distance of 1,619 to 1,680 yd at 5° elevation. It could also fire canister shot, common shell, and spherical case shot. The 12-pounder Napoleon outclassed and soon replaced the M1841 6-pounder field gun and the M1841 12-pounder howitzer in the U.S. Army, while replacement of these older weapons was slower in the Confederate States Army. A total of 1,157 were produced for the U.S. Army, all but a few in the period 1861–1863. The Confederate States of America utilized captured U.S. 12-pounder Napoleons and also manufactured about 500 during the war. The weapon was named after Napoleon III of France, who helped develop the weapon.
The M1844 32-pounder howitzer was a bronze smoothbore muzzle-loading artillery piece adopted by the United States Army in 1844 and employed during the American Civil War. It fired a 25.6 lb (11.6 kg) common shell to a distance of 1,504 yd (1,375.3 m) at 5° elevation. It also fired canister shot and spherical case shot. The howitzer was originally designed to be used in a mixed battery with 12-pounder field guns. However, at the time of the American Civil War, the howitzer was replaced by the M1857 12-pounder Napoleon, which combined the functions of both field gun and howitzer. Only a few 32-pounder howitzers were produced, and they were used sparingly as field artillery during the Civil War because of the weapon's great weight.
