ItPsv 90 Marksman SPAAG

Due to its special geographical location, the Finnish army has always been independent in the development and procurement of weapons and equipment. It prefers the "mix and match style" of the East and West camps, such as the "Leopard 2 Marksman" in the picture. The self-propelled anti-aircraft artillery (SPAAG) is a hybrid product of the "British "Marksman" anti-aircraft artillery + German "Leopard 2" tank chassis.

Finlands first anti-aircraft tank was a Swedish-made Swedish-madeanother Landsverk Anti 2. This was followed by the Soviet SU 57-2, which9 pieces were acquired.The third generation was built on a Polish-made T-55 platform and a British-madeItPsv90 Marksman with a tower. It was an anti-aircraft armored car in the 1980sin practice, the only possible alternative for Finland. West German Ge-the bard wagon was too expensive and impossible to obtain under the YYA contract. Soviet Unionbeen willing to sell its Tunguska wagon, and not as a complex system would have been very well suited to Finland.

"Leopard 2 Marksman" (Leopard 2 Marksman) is actually improved from ItPsv 90 "Marksman" (Marksman) self-propelled artillery. The biggest difference between the two is the chassis. ItPsv-90 uses the Soviet-made T-55AM tank chassis. The "Marksman" series of self-propelled anti-aircraft artillery is mainly used to intercept enemy fixed-wing fighters, military helicopters and unmanned aerial vehicles at low altitudes, and can also be used to suppress ground targets with firepower when necessary. The Finnish Army purchased 7 ItPsv-90s in 1990, all of which were assigned to the tank battalion to perform accompanying field air defense missions, usually using 2 as a combat formation. However, due to the limited chassis size of the T-55AM, with the "Marksman" anti-aircraft turret, despite the excellent combat performance, the operators were dissatisfied with the small internal operating space.

After the first generation of "Marksman" was retired, the Finnish Army did not want to give up this advanced self-propelled artillery. Later, in 2015, it switched to a German-made "Leopard" 2A4 tank chassis equipped with a "Marksman" turret, "Leopard 2 Marksman" was born.

The Marksman anti-aircraft artillery turrets installed on Army bases have been in storage since 2010 due to the obsolescence of T-55 platforms. Still fully functional, by 2015 the system was mounted on the newer platform of the Leopard 2 A4 tank. This will significantly improve the air protection of mechanized combat units. On 05 August 2015, the Finnish Army presented recent equipment purchases in Parolannummi in Hmeenlinna. They contribute to safeguarding the credibility of Finland's defense by maintaining the mobility of the ground forces and firepower as required by modern land warfare.

One of the innovations was the installation of the Marconi Marksman anti-aircraft system on the Leopard platform. The transformation work was done by Millog in Finland in 2014-2015. The English company Marconi designed the Marksman Tower in the late 1980s to be installed on a variety of armored platforms. In the end, it was bought only by Finland. In the Defense Forces, the system is known by the abbreviation ITPSV90. The platform was a Polish-made T-55AM.

The large and high turret has two 35 mm automatic cannons manufactured by the Swiss Oerlikon. They have a total of 460 fragmented grenades in the tower. The outer edges of the weapons contain an additional 20 caliber ammunition suitable for firing armored targets for each cannon. The Marconi Series 400 radar antenna is at the back of the tower (on the left, click on the images to enlarge). In motion, it is lowered backwards. The trolley is capable of rapid fire detection and accurate shooting.

Marksman is suitable for combating various battlefield fast-appearing air targets. These include low-flying combat helicopters and assault planes. Today, unmanned aerial vehicles are also typical targets for such a system. Since 2010, the Marksmans had been in maintenance storage. However, they have been used at least once a month. This has ensured that the systems remain usable.

The Marksman turret had been tested installed on a Leopard 2 A4 platform. They were released for conversion into anti-aircraft use after the Defense Forces purchased 100 newer Leopard 2 A6 tanks from the Netherlands. A fitting ring 10 centimeters wide was required for the new installation. Leopard 2 Marksman proved to work in test shots and were put into service in 2016.In the radar measuring position, the carriage has a height of 4.82 meters and the combat weight of the combination is 49,255 kg.

The width of the leopard base is 370-375 cm depending on the rollers used. Length is 772 cm. The engine is a four-stroke with two turbochargers manufactured by the German MTUa diesel engine fueled with fuel oil. The engine has a displacement of 48 liters andpower 1,100 kW (1,500 hp) at a speed of 2,600 rpm. The refueling is 1,160 liters. The speed of the standard Leopard 2A4 is 68 km / h, but the Leopard 2 Marksmans permissible speed in normal time is 50 km / h.The transmission is automatic. Operators can choose between locked 1-, 2- and 3-speed gears. When reversing with automatic, only gear 2 is used in a change of direction, with selectable positions for forward, backward and stationary rotation.

The turret with its weapon systems is the same as in the previous generation. Combined fire control andthe surveillance radar is the Marconi 400 series. The monitoring distance is 12 km and the monitoring distance is 10km. The radar rotation speed is 60 r / min and the heading range is -10 ... +85 o . On the sides of the tower there are 8 Wegmann protective smoke detectors for self-protection.

The weapons are 2 35 mm Oerlikon KDA cannons. Weapons are always fired simultaneously. The rate of fire is 9 ls / s / weapon, ie the theoretical rate of fire is about 1,100 ls / min. Ammunition is460 fragmented grenades and mainly for self-defense armored topcoats in separatein tanks 40 sub-caliber shots. The fragmentation grenade has an initial velocity of 1175 m/s and an armored grenade 1,385 m / s. Sensors at the ends of the pipes measure the actual output speed andcriticize it for the shooting management system to be used in the calculation of the advance.

The Oerlikon 35mm rapid-fire antiaircraft artillery, which can fire at a maximum rate of 1100 rounds per minute, fires a barrage composed of 35mm anti-aircraft fragments (muzzle velocity of 1175 meters per second), which can effectively destroy various aerial targets within 4 kilometers. Each "Leopard 2 Marksman" anti-aircraft artillery is equipped with 460 rounds of anti-aircraft fragmentation rounds and 40 rounds of armor-piercing rounds.

According to public information from the Finnish army, the self-propelled anti-aircraft artillery has an interception hit rate of 52.4% against low-altitude targets. Compared with similar self-propelled anti-aircraft artillery, its combat performance is very good. The new version of Leopard is great.
