Cancelled or proposed for cancellation. The real question is what this means. Does it mean they leap over one generation of equipment and go for the next one or does it mean that they don't want to spend much on AFV in general? They're already scrapping old AFVs. Defense journalist Victor Murahovskiy is the original source of the news. He was in a round-table discussion with the Russian armaments chief Vladimir Popovkin. The gist of the message is that these are left-over Soviet projects.
It makes no sense to build the tank of tomorrow with yesterday's technology, especially without concrete requirements. Much of the industrial base is antiquated, and production is concentrated in mega-plants that make everything vs having lots of small medium plants concentrating on their core competencies.
Ordnance QF 20-pounder
The ammo situation is dire, control systems are lagging behind a generation, protection systems archaic. What components do we build the next-gen AFV from? We can build wonder weapons in a shed in single-digit series, but it's a waste of money. We decided to stop this practice. This decision is wholly justified, because with a serious military budget we get pathetic results. Money was "successfully" wasted on several armament programmes, but in South Ossetia the army ones again rode BMP-1's and used an ancient comms system.
The defense sector is now awaiting a transformation as radical as the Putin-Serdyukov army reform. PS Things aren't all that bad everywhere. I'm seeing a trend of younger developers in the defense sector, who are doing amazing things, looking at which I feel like exclaiming - Das ist Fantastisch!
BTW, there are quite a few modern 2S19s. They may have issues with ergonomics and vulnerable ammo storage, but on the whole they are in the same league with other MBTs. Such suspensions compensate for uneven ground and can increase the practical seed on rough terrain. As an European, I'd be content if the Russians had no good army equipment at all. Their developments are primarily interesting because they aren't in the Western arms development group think and often come to quite interesting, dissimilar answers to common challenges.
However now I have trouble justifying development of a new gun and munitions line for it. Instead, maybe one could adapt a mm howitzer. It could retain some of its indirect fire capability, but perhaps sacrificing the zone charge system for simplicity.
Sven, In order to take advantage of the greater AA range, won't a 75mm-equipped vehicle require a radar and more sophisticated fire control? It is larger than your 75mm though. Currently, militaries use autocannons and MGs for suppressive fires. I admit, firing one 75mm round per second would be impressive, but it would deplete its ammo rather rapidly.It was developed in by Rheinmetall-Borsig AG as a successor to the 3.
After the Spanish Civil Warthe German authorities started to think that a new anti-tank gun would be needed, even though the 3. They asked Rheinmetall-Borsig to produce a new and more capable AT-gun. The gun was also equipped with Panzergranate 40 APCR shots with a hard tungsten carbide core, in an attempt to penetrate the armor of the heavier KV-1 tank.
Although it was replaced by more powerful weapons, it remained a useful weapon and remained in service with the Wehrmacht until the end of the war. The Pak 38 carriage was also used for the 7. Romania imported Pak 38s in March The guns remained in service with the Romanian Armed Forces untilwhen the 57 mm anti-tank gun M ZiS-2 replaced them.

A possible joint effort in gun development by Israel Military Industries and turret and automatic loader development by Otobreda was envisaged. However, this joint effort did not materialise and both companies have now developed their own ammunitions, guns and applications. As far as it is known this 60 mm weapon has not entered operational service with the Israeli Defence Force. As of mid, the Italian version also remained at the prototype stage.
The HVMS weapon system is designed primarily for infantry support and can be mounted on relatively light vehicles such as the United Defense M APC type to increase the firepower available to infantry units. In addition to being used against armoured vehicles, the HVMS 60 can also be used to engage helicopters and fortified field positions. The HVMS has a 60 mm autofrettaged barrel with a fume extractor about halfway along the length of the barrel.
The breech mechanism is of the vertical block type, and firing is electrical. A hydrospring recoil system is fitted around the barrel to allow easy barrel replacement in the field without special tools. The gun is installed in a two-man welded steel turret designed by Israel Military Industries with an inner diameter of 1, mm and a total weight of about 2, kg.
Several other installations have been developed by replacing the original guns in light tanks, for example the M24, to increase and modernise their firepower. A prototype towed system has also been developed.
Two types of loading system are under development. One version is recoil powered and has two three-round magazines mounted on the gun. This loader allows firing of a three-round burst in 3 seconds or semiautomatic fire. The other system is hydraulicaliy power assisted. Israel Military Industries has developed a two-man turret for this weapon, details are given in the AFV turrets and cupolas section later in this volume.
As far as is known this turret remains at the prototype stage. Early in production of this weapon had begun for export, installed in a Sherman tank. Chile has installed this weapon in a number of its M24 Chaffee light tanks. In the Sherman application a new mantlet and new ammunition racks are needed. It is not known which of the two loading systems was adopted for the Sherman application, although it could be a manual loading system.
The two-man turret version has been installed and demonstrated on various existing APCs including the M and the Marder 1. As far as is known this weapon has not been adopted by the Israeli Defence Force. Specifications: Property.

Specifications: Property Value Main weapon caliber mm.These Shermans had already been owned, upgraded and operated by the Israelis, who then sold them to Chile in the early s.
Chile bought 65 of these tanks, who in turn, requested that they be modified once more. This modification included the replacement of the main gun with a 60 mm 2. Bythe M4 Sherman had been in active service with one country or another for 41 years. The Ms served alongside the far more modern French AMXof which 21 were purchased in the earlys. The Shermans were replaced by the German Leopard 1Vin Chile is a long, thin country located on the west coast of South America, with the Andes mountain range forming its eastern border.
The country has seen a number of internal conflicts throughout its history. The last major conflict Chile fought was against Peru and Bolivia in what is known as the War of the Pacific This resulted in a Chilean victory, but tensions between the three countries survive to this day. Chile has not taken part in any major international war in the 20th or 21st Centuries. InChile only broke diplomatic connections with Germany.
It was not until that Chile would declare war on Japan as part of an agreement between the US and Chilean Governments. Diplomatic repercussions caused by the fact that Chile did not declare war on Germany resulted in reduced support from the US in the post-war years.
Chile has maintained a very tense relationship with its neighbors, especially Argentina. However, it has taken — and does still take — part in a number of United Nations Peacekeeping missions across the globe.
The M variant was not the first type of Sherman to be employed by the Chilean Army. This treaty, still in effect to this day, was signed in Rio de Janeiro, Brazil, by multiple countries in the Americas. In a similar line to NATO, the principal article of the organization is that an attack against one is to be considered an attack against them all. Chile then acquired a further 46 from commercial sources.
There was another spacer on the drive sprocket. The spacers allowed the addition extended end connectors to be fitted on both sides of the track, giving it a wider track. Other upgrades included the addition of the newer vision cupola for the commander and a new hatch for the loader. The tank retained the standard 75mm M3 gun. They remained in service with the Chilean Army into the mids.
By the time the Chilean Army got hold of their M Shermans, the tanks had already changed hands at least two times during their existence, making the South American buyers the third owners of these specific tanks.
Originally, of course, the Sherman was an American tank which entered service with the Allies in They also continued to serve with numerous countries after the war had ended. In the late s, Israel found itself in need of tanks but was unable to purchase any directly, so instead, started scouring the scrapyards of Europe and acquired demilitarised Shermans which they brought back into service, ironically some of which had German guns.
Over the next 20 or so years, this hodgepodge of all varieties of Sherman — from M4 to M4A4 — went through several upgrade programs. In the early s, with help from the French Military, a program began with the intent to upgrade their M4s.
Along with this gun, all tanks were given a mobility improvement with the addition of the Horizontal Volute Spring Suspension HVSS system and the Cummins V-8 horsepower diesel engine. By the early s, the 75 mm armed Ms were being phased out. The mm armed M would stay in service until the early s. Once retired, Israel chose to sell them. Twenty-seven of these tanks were dispatched to Chile in The 27 tanks arrived and were disembarked at Iquique, a port city in Northern Chile.Although designed before the start of the war, it did not reach service until the North African Campaign in April There, it replaced the 2-pounder as an anti-tank gun, allowing the 25 pounder gun-howitzer to revert to its intended artillery role.
Limitations of the existing 2-pounders were apparent even as the gun entered service and an effort was made to replace it with a much more capable weapon starting as early as Guns of this calibre had been employed by the Royal Navy from the late 19th century and manufacturing equipment was available.
The gun design was complete by but the carriage design took until The loss of equipment - most of the heavy equipment of the British Expeditionary Force BEF was left behind in France during Operation Dynamo - and the prospect of a German invasion made re-equipping the army with anti-tank weapons an urgent task, so a decision was made to carry on the production of the 2-pounder, avoiding the period of adaptation to production and also of re-training and acclimatisation with the new weapon.
It was estimated that 6-pounders would displace the production of 2-pounders.
90 mm gun M1/M2/M3
Unlike the 2-pounder, the new gun was mounted on a conventional two-wheeled split trail carriage. Optional side shields were issued to give the crew better protection but were apparently rarely used. The 6-pounder was used where possible to replace the 2-pounder in British tanks, requiring work on the turrets, pending the introduction of new tanks designed for the 6-pounder. The Valentine and Crusader both needed to lose a crew member from the turret. Tanks designed to take the 6-pounder were the troubled Cavalierthe Cromwell and the Centaur.
Although the 6-pounder was kept at least somewhat competitive through the war, the Army started development of a more powerful weapon in The aim was to produce a gun with the same general dimensions and weight as the 6-pounder but with improved performance. The first attempt was an 8-pounder of 59 calibre length but this version proved too heavy to be used in the same role as the 6-pounder.
A second attempt was made with a shorter 48 calibre barrel but this proved to have only marginally better performance than the 6-pounder and the program was cancelled in January The 6-pounder was followed into production by the next generation British anti-tank gun, the Ordnance QF 17 pounderwhich came into use from February As a smaller and more manoeuvrable gun, the 6-pounder continued to be used by the British Army for the rest of World War II and for about 20 years afterwards.
Since there was sufficient lathe capacity, the longer barrel could be produced from the start. The M1A2 introduced the British practice of free traverse, meaning that the gun could be traversed by the crew pushing and pulling on the breech, instead of solely geared traverse, from September The M1 was made standard issue in the Spring of A more stable carriage was developed but not introduced. About one-third of production over 4, guns was delivered to the UK and guns were sent to Russia through Lend Lease.
When the United States re-armed and re-equipped Free French forces for the Normandy landings, their anti-tank units received American-made M1s.It had a 3.
It was capable of firing a 3. The 90 mm gun was the US's primary heavy anti-aircraft gun from just prior to the opening of World War II intocomplemented by small numbers of the much larger mm M1 gun. Both began to be phased out in the early s as their role was taken over by surface-to-air missiles like the MIM-3 Nike Ajax.
As a tank gunit was the main weapon of the M36 tank destroyer and M26 Pershing tank, as well as a number of post-war tanks.
Similar weapons were in British, Soviet and other arsenals. There had been several upgrades to the weapon over its history, including the experimental T8 and T9 versions developed in the early s, that were intended to enter service later in the decade. The new design seemed so much better than developments of the older 3-inch that work on the 3-inch T9 was canceled injust as it became production-ready. A few hundred M1s were completed when several improvements were added to produce the 90—mm M1A1which entered production in lateand was accepted as the standard on May 22, The M1A1 included an improved mount and spring-rammer on the breech, with the result that firing rates went up to 20 rounds per minute.
Several thousand were available when the US entered the war, and the M1A1 was their standard anti-aircraft gun for the rest of the conflict.Soviet Anti-Tank Weapons of World War II
Production rates continued to improve, topping out in the low thousands per month. Like the German 88 and the British QF 3. On September 11,the Army issued specifications for a new mount to allow it to be used in this role, which resulted in the 90—mm M2introducing yet another new mount that could be depressed to 10 degrees below the horizontal and featured a new electrically-assisted rammer.
It became the standard weapon from May 13, In anti-aircraft use, the guns were normally operated in groups of four, controlled by the M7 or M9 Director or Kerrison Predictors. Radar direction was common, starting with the SCR inwhich was not accurate enough to directly lay the guns, but provided accurate ranging throughout the engagement.
For night-time use, a searchlight was slaved to the radar with a beam width set so that the target would be somewhere in the beam when it was turned on, at which point the engagement continued as in the day.
List of tank main guns
Inthe system was upgraded with the addition of the SCR microwave radar, which was accurate to about 0. With the SCR, direction and range information was sent directly to the Bell Labs M3 Gun Data Computerand M9 Director, which could direct and lay the guns automatically, all the crews had to do was load the guns. The M3 was also adapted as the main gun for various armored vehicles, starting with the experimental T7 which was accepted as the 90—mm M3.
The test firing of the M3 took place on an M10 tank destroyer in early An unsuccessful anti-tank variant was the T8 gun on the T5 carriage. The gun was an M1 with the recoil mechanism from the M2A1 mm howitzer. Eventually a version of the T8 with the T20E1 gun and T15 carriage was tested; this led to the mm anti-tank gun T8. Two versions of the T15 were made: the T15E1 with single-piece ammunition and the T15E2 with two-piece ammunition.
It was given to the 3rd Armor Division where it was enhanced with additional armor plates. The T19 was a T18 modified in an attempt to reduce barrel wear.
Other versions included the T21, which was intended for wheeled vehicles, and the T22, which used the breech from the standard mm M2 howitzer. The T21 and T22 were designed to use larger powder charges.However, once the 20 pounder gun was found to have inadequate performance against the Soviet Tthe gun was mostly replaced in service by the larger calibre mm L7 gun.
As fitted to the Charioteerit ran through two models:. The gun was fitted predominantly to the Centurion tank, seeing action with British and Australian forces during the Korean and Vietnam War. However, these conventional rounds were rarely used. Line of sight penetration refers to a flat line drawn through a piece of sloped armour, indicating the effective thickness.
The pounder could also fire high-explosive and canister shot shells. From Wikipedia, the free encyclopedia. This article may require cleanup to meet Wikipedia's quality standards.
