Rheinmetalls 130 mm smoothbore technology for main battle tanks (MBT) embodies a significant lethality leap in times of more sophisticated protection systems and increasing threats. As the primary offensive weapon in any army, nations compete to field the best tanks in both peace and war. WebSmoothbore guns first came into service with the Soviets before being adopted by the west. For weapon systems that primarily fire HE shell-like howitzers, IFV (Infantry Fighting Vehicle) the barrels are rifles.There IFV exception with smoothbore low-pressure guns that have a higher diameter and are designed to fire HEAT or missiles against armor targets. By now developments in Soviet tank design meant that the M60 was becoming out-classed by potential enemies such as the T-64 and T-72 and fielding a new tank was imperative. 20-25 mm in length copyright 2003-2020 Iowa State University, unless otherwise noted length.

The use of depleted uranium as a penetrator has resulted in superior armament for U.S. tankers crossing the battlefield. As the Defense Department looks to a future in which U.S. troops may have to fight in megacities that have millions of inhabitants, mortar systems will become more important for street-to-street fighting. energy penetrators of APDS/APFSDS projectiles from certain angles.

Most importantly, the M774 could penetrate the T-72s frontal hull and turret armor, where armor was the thickest. If we look at the conflicts where the M1 have taken part it could be argued that this was the wrong decision as there have been more high explosive rounds fired in anger then armor piercing rounds but we only have such luxuries in hindsight. The British Challenger 2 will get smoothbore (to replaced rifled) with its upgrade to 3. substantial repair in the United States, normally due to IED ambush. The US has pledged to send 31 of its M1 Abram battle tanks, worth an estimated $400m, to Ukraine to help the resistance fight back against the Russian The reason tank guns are smoothbore is the switch from HEAT (High Explosive Anti-Tank) to kinetic energy rounds sabot as the primary anti-tank round. It only helps with accuracy because the gyroscopic effect from the spin prevents the bullet from tumbling in flight. And there is disadvantages to a rifled barrel such as a bit more weight, shorter lifetime and lower velocity due to leaking gasses or friction. What is Superior, the Rifled or Smoothbored Barrel - Tank The mortar vehicle must also stop to allow the crew to fire. If the electronics can survive the acceleration then the slower rotation is not a problem. and 30 mph (48 km/h) cross-country with a governor in the early models, reduced Tl:Dr Becuase of physics the type of rounds an abrams typically fire dont get the benefits of rifling to the same extent as your normal bullet, so it was deemed not worth the extra cost/maintenance.

But the Biden Administration still lacks the speed befitting the stakes, and missing-in-action Abrams tanks are the latest example. By using unrifled barrels, tanks get more kinetic energy out of each round and barrels last longer. Ted, where are ya?
