Marksman is a British short range air defense system developed by Marconi, consisting of a turret, a Marconi Series 400 radar and two Swiss Oerlikon 35 mm anti-aircraft autocannons. It is similar to the German Gepard system in terms of engine performance, ammunition carried and effective range of the ammunition.
The turret can be adapted to many basic tank chassis to create a self-propelled anti-aircraft gun. The only known major operator of the system to date is the Finnish Army, which ordered seven units in 1990. The turrets were fitted on Polish T-55AM tank chassis. The system is known as the ItPsv 90 in Finnish service (Ilmatorjuntapanssarivaunu 90, Anti-Aircraft tank 90, the number being the year the tank entered service). It is considered a very accurate anti-aircraft artillery system, having a documented hit percentage of 52.44%. [2]
In 2010, the Marksman systems in service in Finland were moved to war-time storage. [3] In 2015 work began to install the system on the Leopard 2A4 chassis in order to make up for the loss of mobile anti-aircraft coverage when the Marksman was originally retired. [4]
The new Leopard 2 Marksman was scheduled to enter service in 2016. [5] [ needs update ]
Finland has seven ItPsv 90 Marksman anti-aircraft systems, providing low-level air-defense for tank battalions. The SPAAGs are organically tied to the headquarters company and form teams of two. The vehicles have an all-day capacity, and there is also a back-up crew to ensure combat survivability. The ItPsv 90 Marksman is primarily meant to fight helicopters, low-flying aircraft and unmanned aerial vehicles (UAVs). It is also possible to engage surface and armored targets.
The chassis of the ITPSV 90 Marksman is a Polish T-55AM tank, which has been modified to fit the turret. The AM version was chosen due to the increased weight of the system (a T-55AM weighs 36 tons, while a T-55AM Marksman weighs 41 tons) and the AM has more power (620 hp) than a regular T-55. The weapon system is guided by a British Marconi 400 series frequency agile surveillance and tracking X/J-band radar, which is able to detect targets out to 12 kilometres (7.5 mi) in search mode and 10 kilometres (6.2 mi) in tracking mode. The laser distance measure device functions up to eight kilometres (5.0 mi). The commander and the gun operator both have gyro-stabilized optical aiming devices.
The armament consists of two Swiss 35 mm Oerlikon anti-aircraft guns, with a rate of fire of 18 rounds per second. The fragmentation round has a muzzle velocity of 1,175 metres per second (3,850 ft/s). The effective range is 4,000 metres (4,400 yd). The vehicle is also equipped with eight Wegmann 76 mm smoke dischargers, a 7.62 mm assault rifle, and a flare gun. The turret can traverse a full 360 degrees and has an elevation range of −10 to +85 degrees. The magazines hold 460 fragmentation rounds and 40 anti-tank rounds.
The new Leopard 2 chassis greatly improves mobility compared to the older T-55AM chassis, both on- and off-road. The Leopard 2 chassis is also larger, thus providing a more stable firing platform for the Marksman turret to operate from. [6]
There are three communication radios in the vehicle for fire guidance and communications. The vehicle is operated by three crew members: commander, gunner, and driver.
In 1994, Marconi and South African Denel group announced plans to install a Marksman turret on a G6 howitzer chassis; [7] Marconi also offered conversions for existing users of T-54/55, Type 59, [8] Centurion, M48 Patton, Vickers, [9] Chieftain, Challenger 1 and Leopard 1 tanks. None of these variants were picked up for deployment.
An anti-aircraft vehicle, also known as a self-propelled anti-aircraft gun (SPAAG) or self-propelled air defense system (SPAD), is a mobile vehicle with a dedicated anti-aircraft capability.
The G6, sometimes denoted as the G6 Rhino, is a South African self-propelled howitzer. It was developed as a turreted, self-propelled variant of the G5 howitzer series, mating the gun to a six-wheeled mine-protected armoured chassis. Design work on the G6 began in the late 1970s to replace the obsolescent Sexton being retired from service with the artillery regiments of the South African Army. Serial production commenced between 1988 and 1999.
The Leopard 2 is a third generation German main battle tank (MBT). Developed by Krauss-Maffei in the 1970s, the tank entered service in 1979 and replaced the earlier Leopard 1 as the main battle tank of the West German army. Various iterations of the Leopard 2 continue to be operated by the armed forces of Germany, as well as 13 other European countries, and several non-European countries, including Canada, Chile, Indonesia, and Singapore. Some operating countries have licensed the Leopard 2 design for local production and domestic development.
The Flugabwehrkanonenpanzer Gepard is an all-weather-capable West German self-propelled anti-aircraft gun (SPAAG) based on the hull of the Leopard 1. It was developed in the 1960s, fielded in the 1970s, and has been upgraded several times with the latest electronics. It has been a cornerstone of the air defence of the German Army (Bundeswehr) and a number of other NATO countries.
The T-70 is a light tank used by the Red Army during World War II, replacing both the T-60 scout tank for reconnaissance and the T-50 light infantry tank for infantry support. The T-80 light tank was a more advanced version of the T-70 with a two-man turret—it was produced only in very small numbers when light tank production was abandoned. The T-90 self-propelled anti-aircraft gun was a prototype vehicle with twin machine guns, based on the T-70 chassis.
The ZSU-57-2 Ob'yekt 500 is a Soviet self-propelled anti-aircraft gun (SPAAG), armed with two 57 mm autocannons. 'ZSU' stands for Zenitnaya Samokhodnaya Ustanovka, meaning "anti-aircraft self-propelled mount", '57' stands for the bore of the armament in millimetres and '2' stands for the number of gun barrels. It was the first Soviet mass-produced tracked SPAAG after World War II. In the USSR, it had the unofficial nickname Sparka, meaning "twin mount," referring to the twin autocannon with which the vehicle is armed.
The M247 Sergeant York DIVAD was a self-propelled anti-aircraft gun (SPAAG), developed by Ford Aerospace in the late 1970s. Based on the M48 Patton tank, it replaced the Patton's turret with a new one that featured twin radar-directed Bofors 40 mm rapid-fire guns. The vehicle was named after Sergeant Alvin York, a famous World War I hero.
The PZA Loara is a Polish armoured radar-directed self-propelled anti-aircraft gun system. First and only PZA Loara prototype was based on the chassis of the T-72M tank. The production version known as PZA Loara-A was to be based on the chassis of the PT-91 MBT.
The Oerlikon GDF or Oerlikon 35 mm twin cannon is a towed anti-aircraft gun made by Oerlikon Contraves. The system was originally designated 2 ZLA/353 ML but this was later changed to GDF-001. It was developed in the late 1950s and is used by around 30 countries.
The SIDAM 25 is a self-propelled anti-aircraft gun developed in Italy from the chassis of the American M113 armoured personnel carrier. Due to the choice of basic chassis for the SIDAM 25, components and spare parts were both cheap, and readily available due to the widespread use of the basic M113. Beginning production in 1987, OTO Breda built a large turret to accommodate the four Oerlikon KBA cannons and remodeled the hull of the M113 slightly to provide side-access to the internal space of the vehicle by the addition of a side-mounted door.
The OTO main anti-aircraft tank for intercept and combat was an Italian self-propelled anti-aircraft gun (SPAAG) prototype. Designed and built by OTO Melara, it was armed with a single 76 mm naval gun.
Landsverk L-62, also known as Landsverk Anti II or a combination of both, Landsverk L-62 Anti II, was a Swedish self-propelled anti-aircraft gun construction that was specifically designed for Finland by Landsverk between 1941 and 1942.
The Type 95 is a Chinese self-propelled anti-aircraft vehicle. It is armed with four 25 mm caliber cannons and optionally four fire-and-forget QW-2 infrared homing missiles. It was first displayed publicly at the Beijing Military Parade in 1999. Earlier in development the system was designated Type 90-II and Type 90-III.
ZSU-37 was a Soviet-made, light, self-propelled anti-aircraft gun (SPAAG), developed by the end of 1943 and produced at Works No. 40 in Mytishchi. It was the first Soviet series-produced tracked SPAAG. ZSU stands for Zenitnaya Samokhodnaya Ustanovka, meaning "anti-aircraft self-propelled mount".
The OF-40 is an Italian main battle tank developed as a joint venture between OTO Melara and Fiat, and intended primarily for export sales. OTO Melara would develop and produce the hulls, and automotive components would be provided by Fiat. Initial design work was started by OTO Melara in 1977, with the first prototypes ready by 1980.
The ZSU-23-4 "Shilka" is a lightly armored Soviet self-propelled, radar-guided anti-aircraft weapon system (SPAAG). It was superseded by the 2K22 Tunguska.
The Type 09 is a Chinese self-propelled anti-aircraft vehicle manufactured by Norinco. It is armed with two 35 millimeter cannons and optionally two to four fire-and-forget infrared homing missiles. It started to gradually replace the predecessor Type 95 in 2009. Some military analysts designated the vehicle as Type 07, but the official designation was confirmed as Type 09 on the Theme Exhibition of the 90th Anniversary of Chinese People's Liberation Army in 2017.
The KORKUT is a Turkish all-weather-capable 35 mm self-propelled anti-aircraft gun (SPAAG) developed by Aselsan.
The Skyranger 35 is a short range air defence turret system developed by Rheinmetall Air Defence AG.
The Leopard 2 chassis also provides a much increased mobility over the older T-55AM chassis, both on roads and in the field.
