Self-propelled howitzers are tracked or wheeled artillery systems. These have high degree of mobility and that is their main advantage over towed howitzers. These artillery systems are used as combat support weapons. Normally they provide indirect fire, however, if needed, they also have direct-fire capability. Most of modern self-propelled howitzers are fully or partially armored. In modern combat these artillery systems often exploit their mobility for shoot-and-scoot type attacks in order to avoid counter-battery fire.
So which is the best self-propelled howitzer in the world? Which is the most capable and effective self-propelled howitzer? This Top 10 analysis is based on firepower, rate of fire, ammunition load, deployment and redeployment time, protection and some other factors.
This list only includes self-propelled howitzers, that are currently in service. It does not includes artillery systems that are under development or at the prototype stage.
Currently top 10 self-propelled howitzers in the world are these:
Nr.1 PzH 2000 (Germany)
The Panzerhaubitze 2000 or PzH 2000 is a German self-propelled howitzer. This is a very advanced and extremely capable artillery system. Initially German Army planned to order a total of 1 254 new self-propelled howitzers, however in 1996 a contract was signed only for 185 artillery systems. First of these self-propelled howitzers were delivered to the German Army in 1998. It has also been exported to some countries.
The PzH 2000 has a fully-automatic loading system with ammunition management system. It is compatible with standard NATO 155 mm ammunition. Maximum range of fire is 30 km with standard HE-FRAG projectile and 40 km with rocket-assisted projectile.
Maximum rate of fire is a whooping 9 rounds per minute. This artillery system is capable of Multiple Round Simultaneous Impact (MRSI) firing. It can launch several shells with different trajectories, that would land on the target simultaneously. Such way of firing is very efficient.
The PzH 2000 receives target data via datalink. The gun is automatically laid using the fire control data.
This artillery system has a high level of protection. Its front armor withstands hits from 14.5 mm rounds. Add-on explosive reactive armor can be fitted in necessary.
Nr.2 2S35 Koalytsiya-SV (Russia)
The 2S35 Koalytsia-SV is the latest Russian artillery system. It was developed as a successor to the 2S19 Msta-S. First demonstrator of this self-propelled howitzer was completed in 2006. It was unique and had two 152 mm guns. However for some reason twin-barrel design was abandoned. In 2013 a new prototype of the Koalitsiya-SV was completed. It had a different design and only one gun. A first batch of 12 artillery systems was delivered to the Russian Army in 2015. Currently it is one of the most capable howitzers in the world.
Even though the Koalitsiya-SV resembles the older 2S19 Msta-S, it is a totally different system. It has unmanned turret and is armed with a 152 mm ordnance. It has a fully automated ammunition loading and handling system and utilizes modular charge system. This artillery system can fire a wide range of munitions, including standard and rocket-assisted HE-FRAG projectiles, cluster projectiles with anti-tank submunitions, jammer carrying projectiles. Range of fire with standard projectile is around 30 km and around 40 km with rocket-assisted projectile. A new long-range precision-guided round has been developed. It has a claimed maximum range of 70 km. The Koalitsiya-SV It is also capable of firing older Krasnopol precision guided munitions with a range of 20 km.
Maximum rate of fire is around 8 rounds per minute. It seems that the Koalitsiya-SV is capable of multiple round simultaneous impact firing. This artillery system carries impressive onboard ammunition supply of around 60 to 70 rounds.
The Koalitsiya-SV has a high level of automation. This artillery system is operated by a crew of only 3 soldiers.
This artillery system has a built-in ammunition reloading system at the rear of the turret that allows to load ammunition from resupply trucks.
