Contracts for 328 vehicles to form the 4th Brigade were placed in March / June 2004 for delivery during 2005 and 2006, plus 423 vehicles for the 5th Brigade in February 2005 with deliveries in 2006-07. When the hydropneumatic system is active, the force needed to depress the clutch pedal is approximately 2-2.5 times less than when it is only spring-assisted. The Strykers weight, 36,240lb and size are within the payload limit of the C-130H. Our advanced explosive waste disposal technology has been designed, sited and built to handle Classes 1.1 to 1.6 explosive materials and items. The program was canceled at an early stage. The vehicle is based on the GDLS Canada LAV III 88 light armoured vehicle, in service since early 2001. The vertical space was increased in the 1972 model of the T-62 by slightly raising the ceiling and by adding a new cupola to the loader's side of the turret. On the T-62, the engine exhaust manifolds lead directly to the exhaust port, with no muffler or any other sound damping device whatsoever to control sound levels other than the S-shaped curves of the exhaust ducting. The XM1205 Field Recovery and Maintenance Vehicle (FRMV) was the armoured recovery vehicle and maintenance system for employment within both the unit of action (UA) and unit of employment (UE). This is in contrast to the gross power to weight ratios, which otherwise indicate that the M48A3 (15.46 hp/ton) and M60 (15.75 hp/ton) surpass the T-62 slightly, where a T-62 weighing 37.5 tons when combat loaded would have a nominal power to weight ratio of 15.46 hp/ton. ", Damn, I was looking forward to an article on the BMP-1. Throughout the service of the T-62 in the Soviet Army, it saw all three tank radio models fitted at various points. For a smoothbore, the length of the throat affected by erosion is no longer the primary issue, but rather the throat diameter. The round stowed in the top left slot in both ammo racks are not secured with a hinged handle but by a spring-loaded tab. The large turret ring provided some additional working space for the crew along the axis of the hull, though this was still limited by the ammunition racks placed at the front and back of the hull. If the ejection mechanism were to fail this way, the loader can simply pick up the shell casing from the floor and throw it away by hand or retain it by placing it back in the ammunition rack slot he took it from. The crew was to use its integrated C4ISR suite (communication, computers and sensor systems) to receive, analyze and transmit tactical information via voice, video and data inside and outside the unit of action. Decades later, the .50 BMG was chambered in high-powered rifles as well. The wide turret ring granted the possibility of upgunning the T-62 without requiring serious turret modifications and without bringing repercussions to the working conditions of the crew, unlike the T-54 which was unsuitable for a gun larger than the D10T. The postCold War era is the period in world history from the collapse of the Soviet Union on December 27, 1991 to the present. The MEV can accommodate up to six patients and a medical team. For comparison, the L11A5 weighed 2,650 kg in total. The system is fitted to the vehicles taillight housing. The NLOS-M had a breech-loading, gun-mortar that fired 120mm munitions including the Precision Guided Mortar Munition (PGMM). The smaller inner shaft is connected to the power take-off unit, while the outer shaft is connected to the gearbox itself via the clutch. Some variants are modified by the Army's Comando de Arsenales. The T-72 is known as one of the most numerous tanks in the world today, and the tank is likely to remain in some form of serv With contributions by Mike Ennamorato, including this introduction. [91], M113s and variants such as the M577 are used by various law enforcement agencies around the world (mostly North American), usually by tactical response teams (SWAT) as mobile command posts and siege and hostage rescue vehicles.[92]. Tick the boxes of the newsletters you would like to receive. The additional radio, which could be an R-112 or an R-130M, had a common connection with the commander's primary radio to the single whip antenna on the turret, made possible by the radio frequency filter. In cold weather conditions, a high airflow is undesirable as it would cool down the crew compartment even more by wind chill. [citation needed]. The 120 mortar fires a larger bomb so it can do more damage when it gets to the targetbut the 105 howitzer has 3000 meters more range and is more accurate. For most engagements, where battlesight gunnery would be used, the gunner could aim at the roof of the target and open fire without requiring a range estimate, and have a fairly high probability of hit on account of the flat trajectory of 115mm APFSDS rounds. 4 engine of the Centurion having a naturally higher rated engine speed of 2,550 RPM. FCC weight was eventually raised to 30 tons. In terms of acceleration performance, it is also somewhat helpful as it allows the driver to depress the pedal rapidly when shifting gears. [25][24] After the cancellation of the Bobcat in late 1963, Canada began looking for an off-the-shelf vehicle to purchase instead and as the Canadian Army had kept themselves updated on American armour developments, including having even trialed some M59 APCs during the mid to late 1950s in parallel to the Bobcats development, they decided to purchase the M113A1 series as it fit the desired roles for use. Before that point, the gun will simply remain stabilized after every shot. Steering is accomplished by engaging a planetary reduction gear, reducing the output speed by 1.42 times. In Iraq, in January 2004, Stryker vehicles were outfitted with a cage of slat armour, which encircles the vehicle about 18in from the main body, as protection against rocket-propelled grenades (RPGs). Below the waist, however, the width of the loader's station is only comparable to the T-54 because the width of the hull is practically identical. For the Space Shuttle program a further unmanned vehicle was parked outside the exit of the crew evacuation bunker for use by the spacecraft crew as an emergency evacuation vehicle. More info here: http://www.kotsch88.de/f_t-55am.htm4, 115mm round performance is not entirely correct. In February 2009, BAE Systems was awarded a production contract for the Check-6 thermal imaging drivers rear-view camera (DRVC) system for the Stryker ICV. Krasnopol projectiles are fired mainly from Soviet self-propelled howitzers such as the 2S3 Because all three tank radios share identical dimensions, it can be assumed that the frame was not modified throughout the service life of the T-62. The MGV program was intended as a successor to the Stryker of the Interim Armored Vehicle program.. The TKN-2 was a sufficiently modern surveillance device for its time. As stated very plainly - "There is no specific norm for loading the gun itself, only readying it for the first shot".The gun does not require a second or two to move a few degrees, and the elevation of the gun takes place in parallel with the autoejector. When in use, the gunner turns the dial until the image he sees has maximum contrast. In contrast to this, the speed of the T-62 for each gear at an engine speed of 1,800 RPM (according to the manual) and at 2,000 RPM (rated engine speed) is as follows: At an engine speed of 2,200 RPM, which is the maximum speed of the engine, the tank may reach an absolute top speed of 55.83 km/h in 5th gear. MAIN MENU. As an additional driving aid, the T-62 is equipped with a gun clearance indicator system, which warn the driver if the gun is traversed beyond the width of the tank hull. The first developed anti-tank weapon was a scaled-up bolt-action rifle, the Mauser 1918 T-Gewehr, that They fire projectiles. The drawing below is taken from. The Copperhead was developed as a high-explosive, laser-guided, anti-tank projectile that was fired from a standard M114, M777, or other 155mm howitzer and is considered to be the first smart artillery round, officially known as a cannon-launched guided projectile. According to the 1981 Soviet essay titled ". To prolong the life of both the gearbox and the clutch, it is recommended to practice double declutching when driving the T-62. Whether this is a critical capability is another matter, because the idea of laploading was discarded in the M1 and Leo 2 for safety reasons. Furthermore, the entire seat frame can be folded up and fixed to the turret wall with a wing bolt. HYDRA-70 Family of Rockets / MAULER. The machine gun could be fired from the trigger button on the gunner's control handles, the trigger button on the manual elevation wheel, or with the manual trigger on the back of the machine gun receiver during an emergency situation such as the total loss of electrical power in the tank. In the US Army, the AN/VRC-12 tank radio operated in the 30-75.95 MHz frequency range, the British used the VRC 353 with a 30-75.975 MHz frequency range, while German tanks were equipped with the SEM-25 radio station, which had a 20-69 MHz frequency range. IDM Members' meetings for 2022 will be held from 12h45 to 14h30.A zoom link or venue to be sent out before the time.. Wednesday 16 February; Wednesday 11 May; Wednesday 10 August; Wednesday 09 November ", "PT-16 Main Battle Tank | Military-Today.com", "Podwozia dla Kraba z Korei. The latter method may be necessary if the tank is used in a contaminated environment. The main issue is that shifting from 1st to 2nd gear is harder and requires more skill, but this can be avoided if the terrain is hard enough that the tank can start moving from a standstill in 2nd gear. US Army TACOM ordered 450 DVH Stryker vehicles in July 2010. The hydraulic gun elevation drive was closely modeled on the type used in the 2E12 stabilizer but modified for the new U-5TS gun. The entire tank is covered in all areas except for the rear half of the side skirts, and rear of the hull and turret, and the turret ring is left exposed. Kinds regards. [18], A further development introduced in 2016. To maintain a given point of aim when a tank is moving across uneven ground, the stabilizer must apply a moment of force to the gun that is equal in magnitude and opposite in direction to any external moments. Even abroad, foreign tank crews generally preferred APDS or APFSDS over other ammunition types when targeting tanks. Before the introduction of 3UBM5, a series of new two-part 115mm rounds was created in 1964 for the T-64, which had the new D-68 gun. According to West German testing, the driving range of the T-62 without additional fuel drums on a track with 40% paved roads and 60% off-road trail was 345 km, whereas the Leopard 1 achieved a driving range of 288 km on the same track. Survival of the tank on the battlefield is expected to increase the additional composite armour of both the hull and the turret, as well as the installed PCO SSP-1 OBRA-3 universal self-propelled vehicle system and two 6-gun intermittent grenade launchers. This is much wider than the 122mm D-25T gun which has a width maximum of 480mm when measured at the widest points across its recoil guard, but should not be surprising as the D-25T operated at a lower pressure and had straight-walled cases, being derived from a field gun rather than being designed to be a high velocity tank gun. The C-130 can operate from smaller airfields in more remote locations. The use of a high gear ratio of 6.706 is complementary with the use of spur gears in the final drives, as opposed to herringbone gears or a planetary gear set. To turn on the dome lights, it is only necessary to switch on the master power relay, located behind the driver's station, which connects the batteries of the tank to the electrical network of the tank. Additionally, the T-62 is furnished with three ShR-51 power sockets connected to the auxiliary electrical network. It has an electronic information block showing the tank's technical condition. [16], A common method for understanding the actual power of a cartridge is comparison of muzzle energies. Unlike in an M60, a T-62 driver is unimpeded in his work when seated normally. Moreover, due to the large turret ring, there is enough elbow room for the loader to handle the ammunition. When measuring along the breech housing alone, the width of the gun is substantial, placing it between the 120mm L11 and L30 (483mm wide) and the 120mm Rh120 (500mm wide). The alternative of having the commander place his knees around the gunner's back is also not ideal, because of the lack of space to move freely. However, if compared to the driver's station of a Chieftain with its semi-reclined seat and periscope embedded in the hatch, the driver of a T-62 is clearly worse off in terms of his seated posture. Instead, priority was shifted to a different project named Twardy. TRADOC recommended removing C-130 transportability requirements in 2007 and raising the weight limit to 27.4 tons in requirements drafted in 2007. Unlike the T-34, which had a direct connection between the engine and the gearbox via the clutch, the T-62 has an additional gearbox between the two. I gave a 220 BHN figure for the M60, but did not give any numbers for the M47. They were ok, (but not particularly good) till the 60s, but after that, they got more and more inferior as years passed, to the point that in the 80s, they were absolutely no match to NATO types. It was a part of 3VBM1 from 1964, and 3VBM5 from 1970, where it had no armour-piercing cap. The complete system weighs in at a hefty 320lbs - though rather lightweight for a "heavy" minded battlefield weapon. Mounting the blocks are easy. M106A2 M106A1 mortar carrier modified with a 120mm FM mortar. The full curve is shown in the chart below, where: To quantify the engine dynamics, two metrics are used - engine flexibility (adaptability) and engine elasticity. Two (driver, commander) + nine troops for ICV: Three (driver, commander, gunner) for MGS, 0.50-caliber M2 machine gun, MK19 40 mm grenade launcher or MK240 7.62mm machine gun; 4 x M6 smoke grenade launchers, Understand the impact of the Ukraine conflict from a cross-sector perspective with theGlobal Data Executive Briefing: Ukraine Conflict. They are held together by a pressure plate sprung with 18 coil springs, which was an orthodox design at the time, as diaphragm springs were not used in clutches until much later. Each one is bolted onto a spacer bolted to the surface of the hull and turret. The army has always had a log chain to supply 81mm mortar ammo. Before that the MiG-15/17 and MiG-21 were both very good aircraft for their time. Significant, the PT-91M2 demonstrated a SAVAN-15 French fire control system (SAVAN-15) from Safran, previously used in PT-91M tanks in Malaysia. From the gear ratios available, it can be seen that the spacing of each gear was calculated so that when upshifting at a speed of 2,000 RPM from the 2nd gear to the 3rd gear, and from the 3rd gear to the 4th gear, the engine will not fall below a speed of 1,400 RPM. However, initially, the work progressed at a very slow pace, mainly because the Polish General Staff was also considering the purchase of a newer version of the T-72 (T-72S) or the modern T-80. I did not cite the hardness of the M47's steel, and I did not use the M47's armour hardness as evidence for a figure on the hardness of the armour on the M60. (M for Malaysia) production export variant for Malaysia with a Sagem Savan-15 fire control system, a new 1,000hp powerpack with Renk automatic transmission bringing its top speed to 70km/h. M113A2 MK I DK without Addon Armour, 2004. [19], Other improvements include an upgraded fire control system. The merits of various turret ring protection methods are examined in the study ". Like the ancestral V-2 engine developed during the 1930's, the V-55V has a bore diameter of 150mm and a piston stroke length of 180mm. [15], Some civilians use .50 caliber rifles for long-range target shooting: the US-based Fifty Caliber Shooters Association holds .50 BMG shooting matches. Its vastly more aggressive gearing ratio was needed to obtain sufficient torque multiplication to propel the tank, which was not only heavier, but experienced higher rolling resistances due to its suspension design. The MGS entered service with the US Army in May 2007, with the first operational deployment to Iraq with the 4th brigade, 2nd Division. Nice article. "The holding will call into question many other regulations that protect consumers with respect to credit cards, bank accounts, mortgage loans, debt collection, credit reports, and identity theft," tweeted Chris Peterson, a former enforcement attorney at the CFPB who is now a law Further, the US Army provided a $258m contract modification to GDLS to upgrade 116 Stryker flat-bottom Stryker vehicles to the Stryker A1 configuration in June 2018. [25] Eventually the entire Canadian fleet was using the Diehl tracks, along with the Lynx and later the M113A2 series. The effective range against a standing enemy soldier is 800 meters. I did not write about the DU shells because they were tactically irrelevant already in the mid to late 80's because the T-62 was being chucked out of Soviet warehouses, and also because they were not procured in big numbers and their performance wasn't nearly good enough to stand a chance of defeating new NATO armour (Leopard 2 and M1A1).
