Anti Aircraft Gun Range - (Bofors 40 mm L/70, Bofors 40 mm/70, Bofors 40/70 and similar), is a multi-purpose autocannon produced by the Swedish arms manufacturer AB Bofors (today BAE Systems Bofors) in the late 1940s. as a modern replacement for their very successful World War II-era Bofors 40 mm L/60 gun-design. Originally deployed as a dedicated anti-aircraft weapon, it was replaced by the Bofors 40 mm Automatic AA. It was marketed as L/70 gun, but since its conception has been repurposed as a multi-purpose weapon capable of firing both sabot projectiles and ballistic missiles. The Bofors 40 mm L/70 design has not achieved the same popularity and historical level as the original L/60 design, but it still has a large export and popularity today, being adopted and accepted by 40 different countries. Flag in November 1953.
It is still manufactured and sold (by BAE Systems AB since March 2005), and several different models are available for both field and naval applications. A notable exception is the Bofors 40/70B "variety of fire-fighting vehicles" used in the Swedish Strofe 9040 and Korean K21 military vehicles.

The Bofors 40 mm L/70, like most Bofors autocannons, is based on the same principle as the original Bofors 40 mm Automatic Gun L/60, being essentially a close-fire, self-propelled gun. On which a car carrier is working. it. a recipient, and thus look similar. Despite this, the Bofors 40 mm L/70 is a variant with several major changes compared to its predecessor. The biggest changes are the longer L/70 barrel, double cooling VTS and jacket and the fact that the weapon comes chambered for the more powerful 40×365mmR cartridge (versus 40×311mmR for the Bofors 40mm L/60).

Most important is a new ejection system that ejects the empty cartridge case from the other side to the right, compared to the ejection system in the 40mm L/60, which ejects the case directly from the rear of the gun. This system change almost doubles the power from the previous system.
Bofors 40 mm L/70 Despite being a different development from the older Bofors 40 mm L/60-design, the similarity and success between the two guns has led to both being referred to as "Bofors" or "Bofors 40 mm gun". A gun can sometimes be confused as a weapon.
By the time of World War II, the speed of jets made it possible to take off from Bofors quickly; Length is important. A higher light rate is also required, increasing the number of colors during the gamete period. Bofors considered updating the 40 mm or making the 57 mm design more powerful. And they did both.
The new 40 mm design uses the larger 40×365R round, firing a smaller 870 g shell at 1,030 m/s (3,379 fps). The rate of fire was increased to 240 rounds per minute (4.0 rounds per minute), like the German Flak 43. weight gain. The first version was produced in 1947, adopted as the "40 mm Evakan M/48" in 1948, and entered Swedish service in 1951. Further changes over the years raised the initial rate of fire to 300 rpm (5.0 rounds per second). and later 330 rpm (5.5 rps). Another improvement was the introduction of 40 mm round-the-clock cameras in the early 1970s.

Foreign markets began, as they had done in the past, in the Netherlands and the United Kingdom. It was adopted as the standard NATO pistol in November 1953, and thousands were soon produced. The L/70 was also used as the basis for several SPAAGs, including the fallen US Army M247 Sgt York. The UK's RAF regiment adopted the L70 in 1957 to replace its L60 machine gun, the last example being replaced by the Rapier weapon system in 1977.
In 1979 the Royal Netherlands Air Force acquired 25 KL/MSS-6720 Flycatcher radar systems and upgraded 75 of its 40L70s to form a 25-gun unit for stationary air defence. Improved guns have an increased rate of fire (300 rounds/min), and the installation system provides an additional guide so that it can hold 22 cartridges. A 220 V diesel engine is mounted in the chassis, powered by a Volkswagen diesel engine.
In 1989, the Royal Netherlands Army received 30 Flycatcher systems, each armed with a modified Bofors 40L70G gun (the 'G' stands for 'gemodificeard', 'modified'). In the 40L70G model, the loading mechanism has been improved and the op-back conductor can be identified. The 40L70G gun was also equipped with a radar detector.
In the Swedish Army Combat Vehicle 90 model, the L / 70 autocannon cartridge is installed. The gun is mounted on the ground to fit in the car. New armor piercing and programmable ammunition have also been introduced. Germany has used L/70 guns on the Type 352, Type 333 and Type 332 minesweeper ships, although these will be replaced by the Rheinmetall MLG 27 guided gun by 2008. L/70 guided gun D7B radar until the 1980s. Widely used in anti-aircraft missions in the German Navy and German Air Force until replaced by the Roland SAM.

In 2014, the Indian Army upgraded its L/70 gun to a modern electronic system and a digital fire control system with a light display camera, a laser detector, a fast radar for accurate targeting and the ability to track and -automatic. started doing In all weather conditions. , The gun can be combined with a fire control radar to provide greater flexibility in its placement.
The ZADS EW suite has been used to detect and intercept drones at ranges of 10–10,000 meters and can "kill" drones without using a gun. When a drone is detected, the ZADS shows the direction of the incoming drone, and the day and night cameras adjust themselves according to the target and automatically lock and track it, the system sends the target coordinates to the L-Gun Brings up to 70. A hardware interface is configured. The gun receives setup in 'remote' mode and aligns itself to the target allowing the operator to lock and fire.

Breda Meccanica Bresciana (now Otto Melara) used the Bofors 40 mm L/70 gun in the Type 64, Type 106, Type 107, Type 564 and Type 520 anti-aircraft guns. Developed a CIWS system named DARDO. For the Italian Army and Navy. A newer development from Breda, the Fast Forty, uses two modified Bofors 40s, each with a maximum speed of 450 rpm, as opposed to 240–330 rpm for the L/70 model. For naval use, a 736 round magazine and two feed system are often used. The 120 mm Gun M1 was the United States' most powerful anti-aircraft gun during World War II and the Korean War, with a low finish. And other mobile guns work M2 90mm. Its highest point is about 60,000 feet (18,000 m), which has earned it the nickname of the gun stratosphere.

The M1 was used by the military for air defense from 1944 to 1960, serving primarily in stationary defensive roles, although it was designed to be mobile. It became obsolete with the development of anti-aircraft weapons, and was phased out after 1954. However, the design installed on the M103 tank remained in service until 1974.
The United States Army was working on the first 120 mm gun after World War I, with prototypes being drafted in 1924. The system was considered too heavy and explosive to be useful, and the project was slowly, though not, cancelled. Fully.
In 1938, the Army assessed the need for a new AA system and decided to order a new system for light and heavy duty. The first was loaded with a new M1 90 mm gun, which replaced the M3 3 guns used by the original Beast. For heavy duty, the 120 mm gun design was scrapped and replaced with a new eight-wheeled carriage, designated the 4.7-inch M1 where it was adopted in 1940.
As in the 90 mm, the M1 gun was operated by a battery of four guns, initially with an associated searchlight, SCR-268 radar (later replaced by the improved SCR-584), M10 gunner, and M4 gun data computer. automatically cocking the gun. An M6 tractor was used as the forerunner.

The M1 gun was discontinued during World War II. A battalion of M1 guns, the 513th AAA Gun Battalion, was deployed to the Philippines in February 1945, but never flew an aircraft.
After World War II ended and the Cold War with the Soviet Union began, the M1 rifle was installed in many places in the country.
