(Source: The information in this write-up has been sourced from m829 120mm, apfsds-t The 120mm M829 Armor Piercing, Fin Stabilized, Discarding Sabot-Tracer(APFSDS-T), cartridge is a US developed kinetic energy (KE) armor defeating round. That would depend on the type of round, whether it is a service round or training round or if it is depleted uranium (aka “Sabot”), high explosive anti-tank (HEAT), multipurpose anti-tank (MPAT), or anti-personnel (aka cannsiter). Sending a 250 gr. Natural uranium is about 99.27 percent U-238, 0.72 percent U-235, and 0.0055 percent U-234.U-235 is used for fission in nuclear reactors and nuclear weapons.Uranium is enriched in U-235 by separating the isotopes by mass. The M829A2 APFSDS-T KE munition is compatible with all standard NATO smoothbore 120mm tank cannons. •Time of flight to 2000m <0.5 second delta to 30mm MK258 and MK268. I know all about the 'sabot accelerators' for 30 cal and 50 cal. The M919 APFSDS-T round has greater effective range, penetration capabilities, and tracer burn time than the APDS-T (M791). •GD-OTS has developed a low cost 30mm Target Practice Discarding Sabot-Trace (TPDS-T) round that is ballistically matched to the qualified MK258 and MK268. MK258 Also checked JSP 482 but it doesnt help either. It seems unclear from JSP 392 and ADR. The Soviet 115mm 3BM-6 (Introduced with the T-62's revolutionary new smooth bore gun) and the 125mm 3BM-9 (115mm 3BM-6 scaled up for the new 125mm gun) were 100% steel rods. Available with and without self destruct. Once unlocked, M322 should be the round of choice for the Merkava Mk.3D. The 105 mm Short-Range Target-Practice Discarding-Sabot (SRTPDS-T) C148 cartridge is a NATO-qualified, low-cost training round. Weapon systems for the 125mm tank gun is the APFSDS round. Typical velocities of APFSDS rounds vary between manufacturers and muzzle length/types. Depleted uranium (DU) is uranium primarily composed of the isotope uranium-238 (U-238). penetrator at ~5500 fps. DRDO 120mm Mk-T-2 8.1. This objective is achieved by reutilizing components from M829 APFSDS-T cartridges and reutilizing M1 propellant from Army surplus M4A2 artillery charges. It is used as a training surrogate for all 105mm kinetic energy cartridges, including the M735, M774, M833 and M900. The Cone Tail design ensures thatthe maximum range of the projectile is less than 10km. The armor is, of course, composite (and secret) and is said to be able to withstand a hit from a 120mm APFSDS round, fired from a gun with 55 caliber barrel length. I'm more interested in a sabot that will be left behind shortly after leaving the muzzle. This sub-caliber anti-tank round is essentially a dart made of a depleted uranium (DU) alloy which gives it good performance against nearly all known types of tank armor. The APFSDS design also offered much higher velocity thus giving much better performance. M900 105mm APFSDS-T The M900 Depleted Uranium APFSDS-T [Armor Piercing Fin Stabilized Discarding Sabot - Tracer] cartridge is the primary anti-armor 105mm tank … •Max range <8,000m using “Fort Bliss Hot Day” conditions. A novel design for a low cost, high volume production, APFSDS training round has been proposed for use in 120 mm tank gun systems. It can also be used in the M230 Chain Gun. The tank can fire rounds of depleted uranium (DU), APFSDSs and kinetic energy penetrator. FAP Ammunition FAP is a new type of high-performance, explosive-free, multi-purpose ammunition for fighter planes and fighter-bombers. Muzzle velocity of the round is 1,780m a second and can penetrate 850mm steel armour from a distance of 2,000m. The live round used a monobloc tungsten alloy rod penetrator fitted with aluminium fins, and was carried in a light alloy sabot. A 30 mm cannon plus ATGM may be a better solution than a CT 40 mm cannon alone. DRDO has also developed the Mk-2 version of its earlier 120mm round for Arjun tank. The round has an extremely low drag coefficient giving short time of flight, high accuracy and superior penetration capabilities out to more than 4 000 m. Mecar has developed a number of training rounds, including the M1057 TPFSDS-T round, which provides a ballistic match to any in service APFSDS-T round out to 2,000 metres, and has a range safety template of less than 10 kms. development of 125mm APFSDS is the comparison of L Ratio of DRDO MK-1 and MK-2 round – this parameter was 14:1 for earlier round while the L Ratio of Mk-2 is 20:1. Ive seen a SHLWS for DU and various bits about excepted packages but just need to know what exactly applies to the L27 round. Chinese engineers experimented with depleted uranium but found the cost-to-performance ratio not worthwhile. PACKAGING Two (2) rounds per twin container 12 containers per pallet But I hear those are really inaccurate. Another reason to go with a 30×173 mm is that it might allow an easier upgrade path to 50×288 mm, should a larger calibre be needed. While traditional ammunition is either stopped or deflected when it hits water, Nammo’s 30-mm Swimmer (APFSDS-T MK 258 Mod 1) swims straight through water, thanks to a groundbreaking design on the supercavitating projectile developed in cooperation with the U.S. Navy. For such a powerful round, it also does not cost that much at only 190 SL per shot; the contemporary IPM1 has to pay 220 SL per shot of the inferior M833 APFSDS round. There is … Many Thanks. Punching holes in Soviet tanks at the cost of wearing the barrel out might have seemed like a good option compared to bouncing outdated ammunition off their turrets. T-80UD carries 45 two-piece rounds (projectile and charge), of which 28 rounds are placed in the automatic loader, with the remainder being stored at the driver's station and in the fighting compartment. It can be fired from the L7 and M68 tank cannons and is currently in service with the Canadian Army. As a typical example, the American General Dynamics KEW-A1 has a muzzle velocity of 1,740 m/s (5,700 ft/s). Does anyone make an APFSDS round for anything less than 50 cal. The gun weighs 2500 kg, and has a muzzle velocity of 1700 m/s, when firing firing the 3VBM17 "MANGO" APFSDS round. The long rod tungsten penetrator, of this highly effective anti-armor round, has excellent penetration characteristics with minimal dispersion. The M930 TP round is a low cost training round for the Aden type 30mm weapon. Hi, I was hoping someone could confirm for me whether shot 120mm l27a1 apfsds requires a Class 7 driver. The 25mm x 137 Tungsten Armor Piercing Fin Stabilized Discarding Sabot-Tracer (APFSDS-T) provides superior defeat capability over the M791 APSDS-T round for the Bradley Fighting Vehicle. APFSDS rounds generally operate in the range of 1,400 to 1,900 m/s. ). The 30 mm x 173 APFSDS-T is designed to defeat the armor threats of today and tomorrow, such as infantry fighting vehicles, armored helicopters and other vehicles with heavy protection. The “ancestor” of modern Chinese APFSDS … M829E3 The M829E3 is the Army's next generation 120mm Armor-piercing Tank round. For reference even the unprogrammable version of the Rheinmetall 120 mm DM11 round…called HE SQ RH31 (or HE-FRAG-T) costs more than $3000 a pop. In contrast, a 30×173 mm HE round costs less than $50, while an APFSDS round less than $150. The M929 APFSDS-T has been designed for the Russian type 30mm cannons, as used on the BMP family of vehicles. It has a 30:1 length / calibre tungsten alloy penetrator. Picture it. The APFSDS-T round is available in calibre 25 mm x 137, 30 mm x 173 and as ballistically matched practice ammunition. The design of this round is unusual because of the method of support between the penetrator and the sabot, and also in the way in which the forces are transmitted to the penetrator in order to accelerate it up the bore. The 105mm M724A2 TPDS-T round is similar in external appearance and is ballistically similar up to 2000 meters with the APDS-T Cartridge M392A2. APFSDS round are much easier to counter than HEAT rounds. This round is similar,in appearance and ballistically to the MECAR 105mm APFSDS-T M1060A2/A3 rounds as well asmost other existing APFSDS-T rounds, up to a range of 2.5 km. 14.5mm JDJ, smoothbore 40" barrel. One type is called HEAT (Hi-Explosive Anti-Tank) while the other is called APFSDS (Armor Piercing Fin Stabilized Discarding Sabot). Low-cost training ammunition in support of HEI and MP-T. MK317 Target Practice Discarding Sabot – Tracer (TPDS-T) Training ammunition ballistically matched with APFSDS-T (MK258) MK264 Multipurpose – Tracer (MP-T) Light armor piercing capability with delayed explosive reaction. The best anti-tank round when the M1 entered service was the M774 APFSDS round, but the earlier M735 round was more common in stockpiles, though … [6] This compares to 914 m/s (3,000 ft/s) for a typical rifle (small arms) round. Even though this is a target practice round, the core can cause damage and penetrate armored vehicles. It is designed to simulate the M829-series APFSDS-T service round characteristics at reduced maximum ranges to allow practice firings on short-range proving grounds and training areas. Inert, instructional 120mm APFSDS (Armour Piercing Fin Stabilized Discarding Sabot) L23 projectile. It will be effective towards various surface threats, small to medium sized boats, personal watercraft that can be loaded with explosives, and submerged targets, or it can be fired through the waves before impacting the target. Besides, KETF is basically just a modified version of the naval AHEAD round and using the same smart fuse , so you also have all the 35 millenium CIWS installed , to help bring down the cost. It offers a substantial increase in penetration power, compared to the standard AP ammunition. Drill version of the type issued for use with Challenger Mark 1 tanks in the 1980s. 8. – Muzzle Velocity: 1,590 m/s. The M919 replaces the M791 as the primary armor-piercing cartridge for use in the 25mm M242 Bushmaster. •Trace visible for >3000 meters (5 sec. Russian have introduced anti-tank missiles being fired from the main gun of T-90 tanks and the same concept is also being introduced in Mk-2 version of Arjun MBT. All MBT's today are immune to frontal attacks of less than 800-850mm penetration capability and i speak about the average armor. The M393A3 round is fitted with a new dual safety base detonating fuze, which complies with Mil-Std-1316 and Stanag 4187.
