It is a separate-loading projectile— propellant bags or MACS charges are loaded separately. These "shell guns" were some of the most effective cannons to fall into Southern hands. Weight (pounds) 11705 lbs; Range (yards) 10300 yards; Rate of Fire (RPM) 2 rpm; Used mainly for counter-battery fire, and requiring 8 to 12 horses to transport it, the 60-pounder was a heavy duty piece of kit. ↑ page 42 in Owen "The principles and practice of modern artillery" 260 pounds (118 kg) H.E.

The weapon was a complete artillery system fielding its powerful 203mm gun tube which was sat upon its elevation (-2 to +65 degrees) and traverse (+60 degrees) hardware. The complete projectile weighs 43.2 kg, is 800 mm long and contains 15.8% explosive by weight. As fired the shell weighs 240 pounds and contains a bursting charge of 20.9 pounds of cast TNT which is detonated by a Fuze, P.D., M51A2, Mod. See Also. Proximity, M732. The 8"/55 caliber gun (spoken "eight-inch-fifty-five-caliber") formed the main battery of United States Navy heavy cruisers and two early aircraft carriers.

While most indicate 147 lbs, some indicate 174 lbs but this is thought to be a typo or transposing of numbers. As the USN test ship for this weapon from 1975 to 1979, the USS Hull (DD-945) was the only destroyer ever to mount an 8" (20.3 cm) cannon. A. var script = document.createElement("script"); A total of 5943 rounds were fired between 1 May and 27 July 1953. Guns were fired using a silk bag containing a black powder propellant.

Development work was restarted in 1939 which led to standardization the following year as the "8-inch Howitzer M1".  The breech mechanism was similar and loading two silk bags each containing 43 pounds (20 kg) of smokeless powder gave a 335-pound (152 kg) projectile a velocity of 2500 feet per second (760 m/s). The rise of armored forces in World War II led to the need for artillery that could follow the tanks cross country. Ignition was through a copper lined vent at the breech end of the gun. This page was last edited on 15 December 2020, at 12:18. [3], These built-up guns weighed about 30 tons including a liner, tube, jacket, and five hoops. These self-loading guns with lined monobloc construction and vertical sliding breech blocks weighed about 20 tons. Hazardous Components. United States naval gun terminology indicates the gun barrel had an internal diameter of 8 inches (203 mm), and the barrel was 55 calibers long (barrel length is 8 inch × 55 = 440 inches or 36.6 feet or 11 meters).

[1][6][7] This gun was modified for the experimental Major Caliber Lightweight Gun. Like the British BL 8 inch Howitzer of the First World War (and most other large artillery), the M115 uses a Welin screw for its breech. I believe the piece required over a dozen men to operate, four were required to load a shell. } In January 1975, Livermore was assigned the task of developing a new nuclear artillery shell warhead, the W79, for the Army's 8- inch howitzers. 203mm 8-inch Projectiles The 203mm 8-inch projectiles were fired by the M110 Self Propelled Howitzer, which was designed to be part of a common family of weapons utilising the same chassis components, with the M110 and the M107 Self Propelled 175-mm Gun being essentially the … In its ultimate manifestation, this led to the post-war development of a tracked, fully enclosed, 8-inch howitzer for the US Army. Item: Huge Artillery Fragment from Eight Inch Mortar Shell Construction: Iron Fuzing: Wood drive-fuze adaptor for paper time fuze. The M107 can be fired more than 13 miles and on detonation it produces approximately 1,950 fragments. [1] Each gun could fire about four rounds per minute. Now many of you will be saying “but the Abrams has an effective 1.whatever metre+ defence against Sabot rounds so no way will this 8 inch shell knock it out” What you have to factor in is the IMPACT of large shells. [5] Useful life expectancy was 715 effective full charges (EFC) per liner. One of the proposed munitions was an extended range guided round that would have been around 90 inches (229 cm) long. Four two-turret batteries were established at Salt Lake near Aliamanu Crater (Battery Salt Lake, later Battery Burgess),[8] Wiliwilinui Ridge Military Reservation (Battery Wilridge, later Battery Kirkpatrick),[9] Opaeula Military Reservation (Battery Opaeula, later Battery Riggs),[10] and Brodie Camp Military Reservation (Battery Brodie, later Battery George Ricker). VI, Mod. It was also used in small numbers by the British Army . Delivery systems include, in approximate order of development: 1.

The weight zone of the projectile is indicated by the number squares and prick punch marks on the ogive of the projectile. The idea behind a gun that could fire spherical exploding shells but not solid armour-piercing shot was that large projectiles capable of carrying a large explosive filling could be fired from comparatively light guns: the 8-inch 68 pounder gun intended to fire solid shot weighed 95 cwt (4,826 kg) compared to the 65 cwt (3,302 kg) of the typical 8-inch shell gun. United States developments resulted in nuclear weapons for various artillery systems, after the short-lived M65 Atomic Cannon standard howitzers were used. Condition: Excellent, excavated.The iron is stable and may have been very lightly clear coated years ago. They are easily identified by their short thick barrel and twin recoil buffersabove the barrel. [11][12][13][14] After the war, all of the guns and turrets were scrapped in 1948, along with almost all other US coast artillery. The Mark I–V had many relatively minor differences in the carriages and trails and Mk IV, Mk VI and QF Mk II 6-inch naval gun barrels were used. Range was 17 miles (27 kilometers) at the maximum elevation of 41 degrees. The 260 lb shell at 2,166fps has 8,466.3496 Foot/Tons! The carriage was the same as used for the US 155 mm gun and was also adopted by the British for their 7.2 inch howitzer . These guns were similar to Mark 12, with the same shell weight and maximum range, with the smaller chamber of the Mark 14 gun. d.setTime(d.getTime() + 60 * 60 * 24 * 2 * 1000); PP= 8.6 inch/21.844cm and EFF= 7.6 inch/19.304cm. Recovered in Charleston South Carolina during dredging operation. With automatic shell handling and loading, a fire rate three times greater than that of previous 8" (20.3 cm) guns and coupled together with the use of "super-heavy" AP projectiles, these weapons made the Des Moines (CA-134) class the most powerful heavy cruisers ever built. No information about hazardous components. Nuclear artillery shells were part of the U. The turrets were turned over to the United States Army Coast Artillery Corps and remounted as coastal artillery on Oahu. [1] Range was 18 miles 31,860 yd (29,130 m) at the maximum elevation of 41 degrees. appears to … 8 inch was a calibre adopted in the First World War by the British Army.

The W33 remained in service until 1992. The warhead used enriched uranium (code named oralloy) as its nuclear fissile material and could be used in two different yield configurations. document.getElementsByTagName("head")[0].appendChild(script); It was uncertain, striped its lead sabot, and was, in nearly all respects, inferior to that of Schenkl, which, was more certain, and gave about 10 per cent increase in range. Maximum range was 30,050 yd (27,480 m) at the maximum elevation of 41 degrees.[5]. Loading with two silk bags each containing 45 pounds (20 kg) of smokeless powder gave a 260-pound (120 kg) projectile a velocity of 2800 feet per second (850 m/s). RML 8-inch 46 cwt howitzer studded common shell diagram 46- and 70 cwt guns differed in number and type of rifling grooves so studded projectiles were only available for 46 cwt guns, and different automatic gas checks were required for studless projectiles. At 32,584 m (35,635 yd), it had the longest range of any US Army field artillery weapon in World War II . The Marks VI, VII and VIII (6, 7 and 8) were a new design and should not be confused with the stopgap early Marks 1 - 5 of 8-inch howitzer, which used shortened and bored-out naval 6-inch gun barrels. 1-3/4 inch wall thickness. The 8-inch gun M1 was a 203 mm towed heavy gun developed in the United States. 1 cwt (abbreviation for hundredweight) = 112 pounds = 51 kg. [1][4], These simplified built-up guns eliminated hoops to reduce weight to 17 tons.
