M65 Atomic Annie. First U.S. Atomic Gun

110
In the late forties in the United States began work on artillery systems of special power, capable of using shells with a nuclear warhead. The first specimen of this kind to come into operation was the M65 gun. The gun, nicknamed Atomic Annie, was not built in a large series, but took a special place in stories American artillery.

In the interests of the army


The first prerequisites for the appearance of American nuclear artillery took place at the final stage of World War II. Faced with German railway artillery, American troops wished to have their own weapon with similar characteristics. At the end of 1944, the development of the promising 240-mm T1 long-range gun began.

In 1947, the air force was separated from the army into a separate military branch, as a result of which the ground forces were left without their own nuclear weapons. After lengthy disputes in 1949, it was decided to start developing special ammunition for land artillery and guns for them. In May 1950, the T131 project was launched, which provided for the creation of a new 280-mm transportable gun using T1 developments. In parallel, the creation of a special ammunition.

The development of the T131 gun was carried out in the Picatinny arsenal with the participation of several other organizations. When designing, specialists had to solve a number of specific design problems, and some of their proposals were of great interest. For example, the T131 part was taken as the basis for the T1 barrel. The existing 240-mm barrel had a sufficient margin of safety, and it could be drilled to a larger caliber.

280-mm gun needed a special carriage and specific means of transportation. This problem was solved with the help of two regular tractors of a special design. With their help, the gun could move between positions. Deployment took no more than half an hour. The means of transportation of the guns were borrowed from the finished project with serious improvements.

The T131 design process coincided in time with the outbreak of the Korean War, which was the reason for the acceleration of work. The technical project was completed at the end of 1950, and only a few months later the first prototype gun appeared. Then the tests started.

The operation of serial guns began in the first half of the fifties, but officially they entered service only in the 1956. The official army index M65 was assigned to the gun. There was also the nickname Atomic Annie ("Atomic Annie") - a hint of the name Anzio Annie, coined by the Americans for the German high-powered guns K5.

Artillery complex


In fact, within the framework of the T131 / M65 project, they created a whole artillery complex, which included all the necessary devices and systems - from guns and ammunition to transportation means and communication systems. The complex also included individual vehicles for calculation and ammunition.

The T131 / M65 gun was a rifled gun with a caliber of 280 mm. A trunk length of 38,5 feet (11,7 m) was used. The breech was equipped with a piston shutter, diverted down. The barrel was fixed on a swinging part with developed hydropneumatic recoil devices. Using a hydraulic actuator, vertical aiming was carried out in the range from 0 ° to + 55 °. The barrel could move on its mounts along its axis. For transportation, he lowered to a horizontal position, and then retracted backward, shifting relative to the mounts. After that, the barrel did not protrude beyond the gun carriage.

The swinging part with the gun was fixed on a special T72 carriage. It was made in the form of a solid frame with developed side walls, between which the swinging part was suspended. A support plate with a diameter of approx. 3 m. A smaller plate was located at the other end of the gun carriage. The main support had an axis on which the carriage rotated for horizontal aiming within a sector of width 15 °.

T72 was equipped with its own power plant, which ensured the operation of the drives. Hydraulics was responsible for aiming in two planes and for supplying the components of the shot to the barrel. There were also redundant manual drives. A characteristic feature of the T72 gun carriage was the presence of additional buffers that extinguished the remaining recoil momentum.

The carriage with the gun was transported using a pair of special tractors developed by Kenworth Truck Company. M249 and M250 machines, with the help of special restraints, had to pick up and lift the T72 product. At the same time, a design with two joints was formed, which has sufficient mobility, cross-country ability and maneuverability.

The "leading" M249 was a tractor with a front cab, an 375 horsepower engine. and wheel formula 4x4. The “closing” M250 machine had the same composition of units, but differed in a rear-mounted cab, in front of which was placed a fork for lifting the carriage.

Before firing, the M65 complex was supposed to arrive at the position, after which the T72 carriage was lowered to the ground, the tractors retreated, and the gun was put into combat position. To leave the position it was necessary to lay the barrel and hang the carriage between the tractors.

The total length of Atomic Annie in the stowed position reached 26 m, in combat - less than 12 m. The transport height was not more than 3,7 m. The total mass of the complex reached 83,3 m, of which 47 m was a gun mount. The maximum speed of the complex on the highway is 45 miles per hour (more than 70 km / h).

Shells for M65


The objective of the promising weapon was to defeat important enemy targets at the operational and tactical depth using conventional and nuclear shells. For M65, there was only one conventional munition - the high-explosive T122. This product had a mass of 272 kg and carried 55 kg of explosive. The initial velocity of the projectile reached 760 m / s, the maximum firing range - 28,7 km.

In the early fifties, the first American artillery shell with a nuclear warhead was created - W9. The 280 mm product had a length of 1,38 m and weighed 364 kg. In the shell of the shell was a nuclear device of the cannon scheme with 50 kg of enriched uranium. The estimated blast power was 15 kt TEQ. The shell accelerated in the barrel to 630 m / s and could fly at 20-24 km.

In 1955, the W19 shell appeared, which was an upgrade of the previous W9. It was slightly longer, but weighed 270 kg and carried a charge of similar power. Due to the reduction in mass, the initial velocity was increased to 720 m / s, and the range to 28 km.

Guns in the ranks


Testing of individual M65 system components began in 1950-51. In the spring of 1951, a full-fledged artillery complex, built as part of the cooperation of several organizations, was sent to the Nevada training ground. For some time, the tests consisted of checking the components of the system, and firing was carried out only by practical and high-explosive shells.

20 on January 1953 The T131 gun was first shown to the public. It took part in a parade dedicated to the inauguration of President Dwight Eisenhower. The new weapons expectedly attracted attention both in the United States and abroad. Published data on him became an additional incentive for foreign projects of atomic artillery.

In May of that year, one of the M65 guns was involved in the Upshot – Knothole nuclear test. On May 25, a test blast took place with the Grable code - Atomic Annie sent a real W9 shell to a conditional target at a distance of 11 km. This was the first and last case of the use of special weapons with a nuclear projectile in American practice.

By this time, mass production of guns was launched. In just a few months, they built a total of 20 artillery systems worth 800 thousand dollars each (about 7,6 million dollars at current prices). The constructed guns were distributed between several artillery units of the ground forces.

In October 1953, M65 guns appeared in Europe. They arrived in Germany as part of the armaments of the American 868th field artillery battalion. Soon, guns of special power went to South Korea. At that time, nuclear artillery was considered both as a real tool for use in war, and as a means of demonstrating strength and intentions.

End of service


Already in the mid-fifties, the barrel artillery began to lag behind its characteristics from modern and promising missile systems. Tools of special power, such as the M65, had no particular prospects and should have left the stage in the near future.

In the case of atomic artillery, it was not only a question of tactical and technical characteristics. Of great importance were the military-political consequences of the presence of such weapons, as well as questions of prestige. For this reason, the army was in no hurry to abandon Atomic Annie, even when obsolescence became apparent.

M65 was withdrawn from service only in 1963. By this time, the army received new, more advanced models of tactical nuclear weapons, showing obvious advantages over the gun. The development of technology has allowed the creation of new nuclear shells of smaller calibers, compatible with existing weapons. As a result, "Atomic Annie" became the first and last cannon, originally created for a special munition.

After decommissioning, the fate of the M65 guns was different. More than half of the products went to remelting. Seven guns were preserved in museums. Some of them are shown only with a gun carriage, but several complete complexes with standard tractors have been preserved. Of most interest is the cannon from the Fort Sill Base Museum. It was she who, in 1953, participated in the Grable tests and fired a single shot with a real nuclear projectile.

The M65 gun has a special place in the history of US artillery. It was the result of a single attempt to create a specialized weapon for a nuclear shell. The resulting product had limited prospects and quickly became outdated. For this reason, the concept of a separate atomic weapon of special power was abandoned. Much more profitable was the introduction of special shells of smaller caliber in the ammunition of other guns and self-propelled guns.

                      Another fabulous character. There is no such document. There is a tool form. But the number of shots by default cannot be a guide to categorizing the barrel. Because such guns do not fire a single projectile, a single charge once an hour and in the table conditions of fire.
                      Therefore, there are objective methods for determining barrel wear. And not the "average for the hospital", which some "genius" has picked up somewhere and launched on the Internet.

                      In short, do not count shots, but use PZK. Instrument for measuring the extension of the charging chamber

                      But in this ficus-picus, Gorbachev "merged" with the Chinese a year before the signing of this agreement, on February 4, 1989. Moreover, the 39th Army began to withdraw the main "strike force" from Mongolia in mid-May 1989. At the same time, large reductions were taking place in the ZabVO and FarVO, most of the units were transferred to the category of cropped ones.
                      So if the "Peonies" went beyond the Urals for some reason, it was only in order to settle at the GRAU storage bases.

                        Why not after a total solar eclipse?

                        In short, "nuclear artillery" never appeared, even in virtuality. Thanks to the 203mm concrete-piercing shell. Oddly enough, not at all atomic. And no Gorbachev could prevent this.

                        By the way, specially for the "Pion" simultaneously with it developed new shells, HE and HE active-reactive. Moreover, immediately after the appearance of 2S7 in the troops, work began on the creation of a cluster projectile.
                        A bit strange for an "atomic gun", isn't it? Or maybe she, oh horror, is not "atomic" at all. How the same 2S3 "Acacia" is also not a "nuclear weapon" despite the existence of 3BV3

                        By the way, in the terms of reference for 2S3 it was indicated that it should be possible to fire direct fire, including a cumulative projectile. And the ACS has a direct aiming sight, which you can do without. If you do not "butt" with enemy tanks. It's just that some kind of bunker can be destroyed using a panoramic one.

                        What do you think this should mean? Is the 2S3 really not an "atomic howitzer" but an anti-tank gun?

Near Leningrad and Sevastopol, barrels were changed for wear on the 30th battery: criterion: a drop in the range and accuracy of fire. On the 35th battery, a shell exploded in the bore, knocking out both turret guns; on Krasnaya Gorka, the barrel was changed due to a bursting shell in the bore.

              And this is due not to a certain strong shooting of the trunks, but to the fact that the firing is carried out at long ranges. That is, even a slight deviation of the initial speed due to wear of the bore will creep out into large corrections.

    Look for confirmation of your tales. "Geometry checks" after shooting 60 shells, the obligatory arrival for this of some "technicians" with some super equipment capable of doing this in the field.

    It makes no sense to compare guns with a caliber of 305mm produced at the beginning of the 203th century with a gun of XNUMXmm caliber of the second half of the XNUMXth century.
    The comrade is driven away by inventing a new term "barrel geometry change". How does he imagine it ?! The trunk has become crooked ?! What amendments to the settings for shooting he was going to introduce "on the curvature of the barrel" ?!
    There is wear on the bore and it depends on many parameters, and the trunks are made with a margin of safety. And in the installation for firing, an adjustment is made for the wear of the bore. And anyway, if the resource on a 305mm gun barrel was 100 rounds at full charge, then on a 203mm barrel fired half a century later, every resource would be higher.

      This is all understandable, not clear to Comrade Matvey. At the beginning of the 203th century, RI, only bonded barrels of carbon steel were made. Equipment and technology for the production of liners and the re-barrel of 180 mm cannons to a caliber of 30 mm were purchased by EMNIP in Italy in the early 12s. Equipment for the production of large-caliber liners from 16 "to 305" (406-XNUMXmm) was ordered and purchased in Germany. So it is not surprising that the resource of a liner made of high-alloy steel will be much higher than a monoblock barrel made of high-quality carbon steel.

      Do not talk nonsense! What fright will it change ?! I, as a professional artilleryman, will tell you the secret that the length of the charging chamber changes due to its height.
      With prolonged firing from a gun, an increase in the volume of the charging chamber occurs due to its lengthening from the height. This leads to a decrease in the loading density Δ and a decrease in the initial velocity V0, which reduces the firing efficiency and increases the dispersion of shells.

      The extension of the charging chamber can be determined using a special chamber measuring device (CCD), consisting of a bar with divisions in millimeters and a measuring ring, the diameter of which is close to the diameter of the leading shell of the projectile. Trunks with lengthening the charging chamber, which has reached the limit at which shooting becomes ineffective, are discarded.

      Here you can learn https://studfiles.net/preview/3168756/page:16/
      And if you have a "change in the shape and depth of the rifling, as well as the uniformity of the section" then how did this barrel come out of the plant at all ?! Was he blinded in the cold from manure ?!

    Great article. After all, maybe the author when he wants to give out an interesting article, rather than a mixture of water with repetitions. The gun is certainly interesting, but it’s somehow too monstrous for such a caliber, and the tractors on both sides of the gun carriage in general, in my unique solution, have made the Americans here, in my opinion, superfluous.

      "Excellent article. After all, maybe the author ..."
      Can not.
      The development of the T131 gun was carried out in the Picatinny arsenal with the participation of several other organizations. When designing, specialists had to solve a number of specific design problems, and some of their proposals were of great interest. For example, the T131 part was taken as the basis for the T1 barrel. The existing 240-mm barrel had a sufficient margin of safety, and it could be drilled to a larger caliber.
      Nobody drilled any trunks. Moreover, trunks of this caliber are not monoblocks.
      As a basis, Robert Schwartz took the German 280 mm German railway gun K5. And since the largest shell in the American land artillery was 240 mm (howitzer 240 mm M1), this shell was increased to 280 mm. Not the barrel was bored, but the shell was increased. Even the English Wikipedia knows about this.

Military thought in the 50s of the last century changed, if not monthly, then certainly annually. Still, "monsters from armament" are really big money and the possibility of cutting them and the impossibility of large-scale production, in the absence of a guarantee that a war will start in which they can be used. wink

    Well, you have an argument at the level of "I do not believe in God."

    You know, Matvey, I read your skirmish with comrade Lopatov and I will say that comrade’s argumentation is much more logical than yours. Nuclear artillery, in principle, is one that fired exclusively with nuclear charges. It basically began and ended in the 50s. Products can be counted on the fingers of one hand. Then only artillery systems existed, capable, among other things, to shoot nuclear ammunition. For example, the Tulip mortar or domestic artillery systems of more than 152 mm caliber. It was then that special charges for such systems were created AFTER the artillery system was put into service. Agree, this is nonsense that is put into service, as you say, an atomic artillery system, and the projectile for it will be adopted in a few years. This was never allowed in the USSR.

      Only now, according to the "operators" and throughout the existing literature, the gun was made primarily as a "carrier" of tactical nuclear weapons and was originally conceived as a 210-mm system, but Leningraders "begged" to 203-mm since the B-4 had already been mastered and the special projectile for it seems to have been made since 1965 ... The barrel and breech of the B-4 were taken as a basis, the barrel was lengthened to achieve the required range indicators, as a result of which, when fully charged, it worked at the limit. And by the way, they were kicked out of Germany as "short-range and medium-range nuclear weapons" - no matter how much they were foolish about them.
