Introduction

The Marksman is a modern self-propelled anti-aircraft gun of UK origin. It was developed for the export market but sales have been limited to Finland only. The Marksman is a powerful system with similar performance as the German Gepard and Japanese Type 87.

Layout

The Marksman system uses a large box shaped two man turret. On each side a 35mm KDA autocannon is mounted and a radar is fitted on top. The turret can be used on a variety of chassis but all production models were built on the T-55AM tank chassis. In recent years the existing systems were converted to use the larger and newer Leopard 2 chassis.

Firepower

The Marksman is armed with two 35mm Oerlikon KDA autocannon. Each gun fires at 550 rpm and is supplied with 220 HE rounds plus 20 AP rounds for use against ground targets. The effective anti-aircraft range is 4 km. In a normal engagement 20 to 40 rounds are fired at a single target.

Fire control

Fire control is provided by a single Marconi Series 400 I/J-band radar. This has a surveillance range of 12 km and tracking range of 10 km. Additionally a gyro-stabilized optical sight is fitted for manual use against aerial and ground targets.

Protection

The Marksman is operated under full armor protection. The steel armor protects against small arms fire and shell splinters. Smoke grenade dischargers are fitted and an NBC system is optional.

Mobility

The T-55AM chassis provides for a good cross-country mobility albeit at limited speeds. The 620 hp diesel engine provides a maximum road speed of 45 km/h and range of 400 km. The recent conversion to the Leopard 2 chassis results in a massive boost in mobility. The 1.500 hp diesel engine provides a maximum road speed of 72 km/h and range of 550 km.

Users

The Marksman system was only adopted by Finland. It is believed that up to 10 turrets have been delivered and 7 systems are in use. The Marksman system is no longer marketed.

Variants

Marksman on T-55 chassis

The Marksman has been produced in only a single version using the T-55AM tank chassis. The Marksman can be easily distinct from the German Gepard by the large flat front of the turret, forward mounted armament and the T-55 chassis. For trails purposes the Marksman turret was also installed on a variety different chassis. These include the Type 59, M48 Patton, M60 Patton, Centurion, G6, Leopard 1, Challenger 1, Chieftain and Vickers Mk 3.

Marksman on Leopard 2 chassis

The Marksman was put into storage in 2010, but in 2015 the turrets were installed on the Leopard 2 chassis. The larger chassis is a more stable platform for the Marksman turret. The Leopard 2 chassis also provides a much increased mobility over the older T-55AM chassis, both on roads and in the field.
