The army started receiving the SEPv3 upgrade version of the M1A2 Abrams tank (now dubbed the M1A2C) back in 2017. First upgraded tank was delivered in 1999. In addition to the armor, some USMC Abrams tanks are equipped with a Softkill Active protection system, the AN/VLQ-6 Missile Countermeasure Device (MCD) that can impede the function of guidance systems of some semi-active control line-of-sight (SACLOS) wire- and radio guided anti-tank missiles (such as the Russian 9K114 Shturm) and infrared homing missiles. The round is a modified M830A1 with the front fuse replaced by a steel nose to penetrate into the obstacle before detonation. The Abrams is protected by Chobham composite armor. In December, GDLS also received an order, amounting to around 40% of a US$48 million order, for loader's thermal weapon sights being part of the TUSK system improvements for the M1A1 and M1A2 Abrams Tanks.. Diaz, R. Gary. Soldiers from the 3rd Battalion, 8th Cavalry, 3rd Armored Brigade Combat Team, 1st Cavalry Division were the first to take possession of the SEPv3 back in May of this year. The XM1111 was a guided munition using a dual-mode seeker that combined imaging-infrared and semi-active laser guidance. Just the one.  It is planned for up to 261 Abrams to be upgraded with the system, enough for four brigades. The SEP V2 is a great tank also. Low initial rate production (LIRP) of the vehicle was approved on 7 May 1979. Chrysler and GM entered bids.. Secondly is the presence of the tank infantry phone box next to the right tail light which was added as part of the TUSK (Tank Urban Survival Kit) in the mid-2000's and kept on later M1A2 variants. The 120-millimeter main gun has been shielded with a newly developed, classified armor package. The last major “version” of the M1A2 Abrams was developed in the mid-to-late 2000s, the M1A2 SEP v2.. Engineering Change Proposal 1 is a two-part upgrade process. The known data, the upgrade and installation of new tank units M1A2C noticeably heavier. All of these factors are computed into a ballistic solution and updated 30 times per second. There are three main operational Abrams versions, the M1, M1A1, and M1A2, with each new iteration seeing improvements in armament, protection, and electronics. US Army/Sgt.  The new LV100-5 engine was lighter and smaller (43% fewer parts) with rapid acceleration, quieter running, and no visible exhaust. Quartermaster says: August 14, 2020 at 7:36 PM Phelps, you must not have read the article or watched the video. Just the one. The Army is already eyeing SEPv4 (or M1A2D) upgrades for testing, including "new laser rangefinder technology, color cameras, integrated on-board networks, new slip-rings, advanced meteorological sensors, ammunition data links, laser warning receivers and a far more lethal, multi-purpose 120mm tank round," as Bassett told Warrior Maven back in 2016. Prototypes, early production M1 (105 mm gun) and M1-IP models switched to a flat forest green paint scheme. Its combat weight is increased to 66.8 t is Not clear whether additional means of protection in the form of overhead panels, KAZ and side skirts with dynamic protection. The ballistic computer manipulates the turret and a complex arrangement of mirrors so that all one has to do is keep the reticle on the target and fire to achieve a hit. The canister round is also a highly effective breaching round and can level cinder block walls and knock man-sized holes in reinforced concrete walls for infantry raids at distances up to 75 meters (246 ft). It had to defeat any hit from a Soviet gun within 800 meters and 30 degrees to either side. The M256 can fire two types of combat rounds – sabot and HEAT (High Explosive Anti-Tank). Due to the increased calibre, only 40 or 42 rounds are able to be stored depending on if the tank is an A1 or A2 model.  The high speed, high temperature jet blast emitted from the rear of M1 Abrams tanks makes it hazardous for infantry to take cover or follow behind the tank in urban combat. The M1, named after General Creighton Abrams,first entered service in 1980 and was produced for the U.S. Army from 1978 until 1992. Through this same period, there was an ongoing effort to improve NATO logistics by standardizing ammunition to the maximum possible degree. During Operations Operation Desert Shield and Desert Storm some M1IP and M1A1s were modified locally in theater (in the war zone) by modification work orders (MWO) with additional rolled homogenous armor plating welded on the turret front. It has improved armor protection, improved system components, improved computer components, and some other improvements. Vehicles included in the AOA were determined to be inferior to the planned GCV. The Army bought 3,300 of them.  It also featured a 33% reduction in fuel consumption (50% less when idle) and near drop-in replacement.  Conceived for modern armored ground warfare and now one of the heaviest tanks in service at nearly 68 short tons (almost 62 metric tons), it introduced several innovative features, including a multifuel turbine engine, sophisticated Chobham composite armor, a computer fire control system, separate ammunition storage in a blow-out compartment, and NBC protection for crew safety. , Vulnerabilities exposed during urban combat in the 2003 invasion of Iraq were addressed with the Tank Urban Survival Kit (TUSK) modifications, including armor upgrades and a gun shield, issued to some M1 Abrams tanks. The loader's M240 machine gun is aimed either with the built-in iron sights or with a thermal scope mounted on the machine gun. With the engine governor removed, speeds of around 60 mph (97 km/h) are possible on an improved surface; however, damage to the drivetrain (especially to the tracks) and an increased risk of injuries to the crew can occur at speeds above 45 mph (72 km/h).  There is no evidence that GM considered using the MTU engine of the MBT-70, which outperformed both and had been chosen for the Leopard 2K. The commander's M2HB .50 caliber machine gun on the M1 and M1A1 is aimed by a 3× magnification sight incorporated into the Commander's Weapon Station (CWS), while the M1A2 uses either the machine gun's own iron sights, or a remote aiming system such as the CROWS system when used as part of the TUSK (Tank Urban Survival Kit). The new XM24/L55 gun barrel was 18 inches (45.72cm) longer in comparison to the XM24/L52 barrel used on the M60 tanks. Finally, two new guns were introduced, a US 152 mm design whose primary long-range weapon was the Shillelagh missile, while the Germans introduced a new 120 mm smoothbore design.  The first M1A1 tanks to receive this upgrade were tanks stationed in Germany. Production at the government-owned, GDLS-operated Lima Army Tank Plant in Lima, Ohio, was joined by vehicles built at the Detroit Arsenal Tank Plant in Warren, Michigan from 1982 to 1996. Turret traverse and main gun elevation can be accomplished with manual handles and cranks in the event of a Fire Control System or Hydraulic System failure. The original M1 packed a 105-millimeter gun. Prototypes were made but the program was canceled. A few days ago, the first photo of a modernized tank with a full set of new equipment for various purposes appeared in the public domain.  It has been introduced into service and serves with Stryker brigades. [needs update] In March 2017, it was reported that the new version, the M1A2 SEP v4, is to begin testing in 2021. Chrysler was the only company that appeared to be seriously interested in tank development; the M60 had been lucrative for the company and relied on that program for much of its profit. , The first instance of the Abrams being airlifted directly into a battlefield occurred in October 1993. According to the Army, the M1A2 SEPv3's full improvements include the integration of the US military's Joint Tactical Radio System, highly improved power generation and distribution, a line replaceable modules design for improved maintenance, electronic warfare devices to counter remote-controlled IEDs, and auxiliary power unit, and significant ballistic armor upgrades.  In February 1982, General Dynamics Land Systems Division (GDLS) purchased Chrysler Defense, after Chrysler built over 1,000 M1s. While the reactive armor may not be needed in most situations, like those present in maneuver warfare, items like the rear slat armor, loader's gun shield, infantry phone (which saw use on Marine Corps M1A1s as early as 2003), and Kongsberg Remote Weapons Station for the 12.7 mm (.50 in) caliber machine gun will be added to the entire M1A2 fleet over time.  By 1999, costs for the tank were upwards of US$5 million a vehicle. M1A2 SEP v3 Pilot Vehicles during initial trials, note the lack of weight simulators on turret checks and hull front plate. That month, the U.S. Department of State approved the sale of another 175 Abrams to Iraq. The gas turbine propulsion system has proven quite reliable in practice and combat, but its high fuel consumption is a serious logistic issue (starting up the turbine alone consumes nearly 10 US gallons (38 L) of fuel). The army started receiving the SEPv3 upgrade version of the M1A2 Abrams tank (now dubbed the M1A2C) ... 1999, the vehicle was re-designated the Type 99 and entered service in 2001. By 1977 the decision had been made to eventually move the new tank to a 120 mm gun. This version corrects many of the problems of space, weight and power that … The reactive tiles for the M1 will be locally produced at GDATP's Burlington Technology Center. ... a feature unique to the M1A2C (aka SEP v3), which has only just started to be issued to units of the US Army at the time of this writing. Power to Weight Ratio : 25 hp/ton : 23.8 hp/ton : 21.6 hp/ton : Hydro Kinetic Transmission : 4 Speed Forward 2 Speed Reverse: Speed - Maximum : 45 mph (Governed) 42 mph (Governed) Speed - … D Jan 1987 | Military and Government Specs & Standards (Naval Publications and Form Center) (NPFC). The main armament of the original model M1 and M1IP was the M68A1 105 mm rifled tank gun firing a variety of armor-piercing fin-stabilized discarding sabot, high explosive anti-tank, high explosive, white phosphorus rounds and an anti-personnel (multiple flechette) round. as well as other partner offers and accept our, NOW WATCH: Car builders make hot rods out of World War II fighter plane belly tanks, Visit Business Insider's homepage for more stories, first of about a half-dozen initial production, Here are the weapons and gear that soldiers and Marines can look forward to in 2021. The Army was planning on introducing several new types of ammunition for the 105 that would greatly improve its performance, notably, the XM-774 using depleted uranium. It contains 1,098 3⁄8-inch (9.5 mm) tungsten balls that spread from the muzzle to produce a shotgun effect lethal out to 600 meters (2,000 ft). HEAT and sabot rounds enter the beginning layers of armor but are unable to penetrate the crew compartment. It has a number of upgrades in the area of survivability, maintainability, fuel efficiency, and network capabilities.  Development of the M829 series is continuing with the M829A4 currently entering production, featuring advanced technology such as data-link capability. It is smaller than the turbine, 14% cheaper to operate per mile, and has a four-fan cooling system that is to greatly reduce the tank's heat signature. The GM design used a new variable-compression Diesel design which proved to be problematic. Marines transport their Marine Air Ground Task Force (MAGTF)-attached Abrams tanks by combat ship. The M1 Abrams was developed from the failure of the MBT-70 project to replace the obsolescent M60 Patton. Russia and China both are developing new fighting vehicles. Lessons from the war improved the tank's weapons sights and fire control unit.  In June 2018, the Army awarded Leonardo DRS, U.S. partner to Trophy's designer Rafael, a $193 million contract to deliver the system in support of M1 Abrams "immediate operational requirements. The Army should begin a program to develop a new version of the Abrams, the A3. As the Abrams entered service in the 1980s, they operated alongside M60A3 within the U.S. military, and with other NATO tanks in various Cold War exercises which usually took place in Western Europe, especially West Germany. , In January 1978, a program was initiated to develop an enhanced version of the 105mm gun, the M68A1 as a possible alternate weapon for the M1 Abrams. It was a political decision that was reached, and for all intents and purposes that decision gave the award to Chrysler since they were the only contractor with a gas turbine. Key Points: The cost of the new armor and Trophy APS is greater turret weight, which is likely going to be several tons heavier than what the M1A2 was designed for. The M1A1 was superior to Iraq's Soviet-era T-55 and T-62 tanks, as well as T-72 versions imported from the Soviet Union and Poland. After head-to-head testing between the Royal Ordnance L11A5 and the Rheinmetall Rh-120, the latter was chosen.  Further upgrades included depleted uranium armor for all variants, a system overhaul that returns all A1s to like-new condition (M1A1 AIM), a digital enhancement package for the A1 (M1A1D), and a commonality program to standardize parts between the U.S. Army and the Marine Corps (M1A1HC). The eight-wheeled M1128 Mobile Gun System was designed to supplement the Abrams in U.S. service for low-intensity conflicts. [verification needed]. Other tanks were put out of action by engine fires when flammable fuel stored externally in turret racks was hit by small arms fire and spilled into the engine compartment. The Army team spent the night writing briefs and presented them to Rumsfeld the next morning, who then announced a four-month delay. The M1A2C IMO is a great tank. The ballistic solution generated ensures a hit percentage greater than 95 percent at nominal ranges. , M1A1 AIM/SA: Depleted uranium inserts in hull and turret, Improved Chobham armor and increased turret armor Additions of ARAT ERA, slat armor Some tanks being equipped with Trophy APS, "M1 Tank" redirects here. , Armor protection was improved by implementing a new special armor incorporating depleted uranium and other undisclosed materials and layouts. , In October 2017, Abrams were used by the Iraqi security forces and the Popular Mobilization Forces (also called Al-Hashd al-Shaabi) in assaults against the Kurdistan Regional Government Peshmerga in the town of Altun Kupri (also called Prde). The large white insignia stars have also transitioned to much smaller black markings. In 2016, the U.S. Army and Marine Corps began testing out the Israeli Trophy active protection system to protect their Abrams tanks from modern RPG and ATGM threats by either jamming (with ATGMs) or firing small rounds to deflect incoming projectiles. Efforts to develop an M1A3 version were first publicly disclosed in 2009. This version rectifies many of the space, weight and power issues identified during Operation Iraqi Freedom and will be the foundational variant for all future incremental upgrades. During the invasion, at least nine Abrams tanks were put out of action by fire from rocket propelled grenades. The problem with more passive armor is that it also adds significant additional weight to the Abrams, which could limit its mobility. 2 Responses to “M1A2C Abrams Tank Hits The Field” Phelps says: August 13, 2020 at 3:07 PM So, another bunch of weight slapped onto an undersized turret built using 1970s technology designed for the last, no, wait, for three wars ago.  Either the commander or gunner can fire the main gun. "It is a great step forward in reliability, sustainability, protection, and onboard power which positions the Abrams tank and our ABCTs for the future.". It was reported in 2018 that the Army had ordered 135 tanks re-built to new standards with employment at over 500 workers and expected to rise to 1,000.. During three months, about one-third of the Iraqi Army's M1 tanks had been damaged or destroyed by ISIL and some were captured by opposing forces.  This variant was designated as the M1A1HA (HA for Heavy Armor). Replacement parts (roadwheels, armor skirt panels, drive sprockets, etc.) General Dynamics Land Systems (GDLS), which operates the factory, opposed the move, arguing that suspension of operations would increase long-term costs and reduce flexibility. The V3’s made it easier for crews to do 2 level maintenance in the field while at the same time saving down time of the tank. Australian M1A1s were desert tan when delivered but have undergone a transition to the Australian Army vehicle standard 'Disruptive Pattern Camouflage'; a scheme that consists of black, olive drab, and brown. However, the Abrams' turret features composite armoring across both the front and the sides. , After the start of the Saudi Arabian intervention in Yemen during the 2015 Yemeni Civil War, Saudi Arabian M1A2 MBTs were deployed near the Saudi Arabian/Yemeni border.
