Cockerill 90 mm low-pressure gun is a Belgian amphibious infantry fighting vehiclea low-weight two-person turret. The Cockerill CSE 90mm low-pressure  turret system which commissioned by the Belgian company CMI DEFENCE in Portugal is mounted with the Textron Land & Marine Systems COMMANDO 4x4 vehicle. The combination of 90mm ammunition is mainly Mecar, including HEAT-T, HESH-T and HE-T. Moreover, this turret is also able to launch APFSDS-T, SMK-WP-T cartridges and housings, plus training purposes for 14.5 mm or 20 mm sub-caliber devices.

This is a certain type of  mount Cockerill guns designed double-person turret. The turret is light-weight,wide, comfortable, ergonomic. The CSE90 is well-suited with a variety of light armoured vehicles. Easily stands on many tracked or wheeled platforms. The chief weapon of the CSE90 collection is the 90 mm Cockerill Mk3 low pressure gun. The EE-9 Cascavel, a 6wheeled armoured vehicle is firstly invented in Brazil was used originally for reconnaissance operations. The designer's name is Engesa back in 1970 as an alternative to the old Brazilian gondola team M8. The car was outfitted with the 37mm Greyhound cannon and then the French tower used by the Panhard AML-90. His later work  took a tower made by Engesa, in which a 90mm Belgian Cockerill Mk.3 gun was manufactured with the name CE-90.

History and Usage
CMI stands for Cockerill Mechanical Industries, it is an international organisation which focused on mechanical engineering and services. CMI is mostly active in the energy, metallurgical, defense and transport sectors. CMI-Defense has specialised in weapons systems for light armoured vehicles Since the 1970s. We are now recognized as a world leader in the 90mm caliber pistol system, two of which are the COCKERILL MK3M-A1 and CSE 90 turrets and the 90mm COCKERILL Mk8 pistol and the LCTS turret. The latest version of the 90 mm COCKERILL Mk1, Mk2 and Mk3 low pressure gun series. More than 2,000 weapons are operating worldwide, including ALVIS Scorpion, TEXTRON / CADILLAC GAGE V-150 and V-300, AV-TECHNOLOGY Dragoon, ENGESA Cascavel and Urusus.

The light, compact, soft but short, neat and economical characteristics to operate and hold recoil, capability of launching a variety of firearms, including the APFSDS-T, has proven to be an ideal weapon for vehicles of 7.5 tons or more.

The 90mm COCKERILL Mk3-MA1 pistol can be sold separately or in the CSE 90 turret, a twin turret of a classic building developed specifically for it. The CSE team can be tailored precisely to user requirements and budget constraints, including electromechanical drives, day / night gunners and commander views associated with laser rangefinders and ballistic computers. One hundred and sixty two CSE 90 turrets have been produced and implemented in Malaysia in the SIBMAS 6X6. It is usually related with the CMI LCTS 90 turret, which is a double turret that can be equipped with advanced equipment, such as a fully stable day / night gunner sight with a laser range finder and a ballistic computer that can be moved The panoramic view of the commander in the middle of shooting at the moving target is almost a hunter-killer. The LCTS 90 turret / Mk8 cannon system was deployed in Qatar and Kuwait and handed over to the Saudi National Guard under the FMS plan.

CMI-Defense also uses its experience in light armoured vehicle guns and turrets to offer superior bombing packages for couples of existing turrets.For instance --Replacing 90 mm Cockerill Mk3M-A1 gun with the conversion of 76 mm 90 mm scorpion, consists of the installation of electromechanical power units and upgraded firing control systems.

The superior Kit for 90mm Cadillac Gage V-150 and V-300 turrets, includes upgrades for 90mm Cockerill Mk2 firearms, installation of electromechanical drives and leveled-up fire control systems. Upgrade kit for the Cascavel Engesa EC-90 turret, including the upgrade of the 90mm Cockerill Mk2 gun, the electromechanical power unit installation and the firing control system for the development of the Russian auto rifle PT-76 of 90 mm with our Cockerill Mk3M-A2 Or light tanks of the Mk8-A2 pistol of 90 mm, that includes a system of control of shot improved, a reinfection of 90 mm of the light tank AMX-13 French with a barrel Cockerill Mk3-A4 or Cockerill Mk8-A4 and an improved trigger control system.

The Cockerill CSE 90LP is able to launch a range of ammunition. Nevertheless, launched from a significantly lightweight armoured turret, the 90mm one is outstanding which offers a large payload,

The system can have a significant performance on the target.

This provides with a wide range of tactical options. It comes standard with the gunner's daytime view, in night vision (image enhancement or thermal imaging) as an option.The aim of the weapon is to use a turret propulsion system and electromechanical pistol which allows a quick  movement of the gun and turret during normal operation, as well as an excellent slow tracking of the target for precise coupling. Laser rangefinders and ballistic computers allow precise engagement of the target. The line of sight image of the gunner can be displayed on the commander's site to allow command and total control.

Design and Products
The turret was firstly installed in all the CMI 162 SIBMAS fire support armoured vehicles (AFSV-90) purchased by the Malaysian Army in the early 1980s. CMI no longer participates in the design, development or production of armored vehicles. CSE90 weapon system Armored armored artillery tower 90 mm vehicle design development Belgium Belgium defense industry CMI.

For the test, the Cockerill CSE 90LP turret was also installed in the BAE system Valkyr ground system (4 x 4), the BAE system ground system, Steyr-Daimler-Puch Pandur (6 x 6) and M113A2 APC. As early as 1985, CMI Defense purchased an APC M113A1-B from Belgian Machinery Manufacturing (BMF), which subsequently installed the Cockerill CSE 90LP turret and showed it as a fire support vehicle. In this version, the vehicle can still carry 10 fully equipped infantry plus three crew members, commanders, gunners and drivers. To maintain the amphibious vehicle, the floating panels have been connected to both sides of the hull. To our knowledge, the only production application for the Cockerill CSE 90LP turret is the SIBMAS vehicle. In June 2010, CMI Defense announced a new contract to supply 22 Cockerill CSE 90LP weapons systems to the Indonesian Ministry of Defense. These turret systems will be equipped with the new Doosan 6x6 "wolf spider" vehicles (also known as black fox). Indonesian defense company PT Pindad presented its version of the Anoa-2 6x6 armored vehicle at IndoDefence 2010, equipped with the CMI Defense Cockerill CSE 90LP turret gun system.In Eurosatory 2014, the Cockerill CSE 90LP in Textron Commando showed the interest of many delegations in the stand of Defense CMI.The combination of the Cockerill CSE 90LP turret and the Ukroboronservice BTR-3E service provides users with superior strategic and tactical maneuverability, efficient organic fire support during the day and night, and extensive tactical options (from rebellion to conventional operations). ), simple use and support, robust reliability on the site, confidence in proven service systems.
