RCH1 155: Revolutionary Self-Propelled Artillery System

Introduction

The world of artillery is on the brink of a major revolution with the introduction of the RCH1 155 self-propelled artillery system. This innovative weapon system promises to change the face of artillery warfare by enabling something that was previously thought impossible - firing artillery shells while on the move. The Ukrainian military is set to receive their first batch of 18 out of 54 of these cutting-edge systems by the end of 2024, marking their combat debut. Great Britain has also placed an order for 116 units, and there are hints that the US military might be interested in acquiring this system as well.

The Evolution of Mobile Artillery

Early Attempts at Mobile Artillery

The concept of mobile artillery is not new. In fact, it dates back to World War I when innovative military minds first experimented with mounting cannons on moving vehicles. One of the earliest examples was the 1917 French Schneider CA1, a tank that featured a 75 mm field gun mounted on top. While this wasn't purpose-built self-propelled artillery, it demonstrated the potential of mobile gun platforms.

Advancements in Stabilization Technology

The real breakthrough in mobile artillery came in the 1950s with the development of stabilization technology. Early versions featured single-plane stabilizers, which helped tanks keep their guns steady on one vertical axis. The American M4 Sherman tank was one of the first to incorporate this technology.

These early gyroscopes would send feedback to an electrohydraulic system connected to the gun's elevation mechanism. If the tank pitched forward or backward, the stabilizer would adjust the gun's elevation in real-time to counteract the tank's movement and keep the gun aimed at the target.

Two-Plane Stabilization Systems

The next major advancement came with the introduction of more advanced two-plane stabilization systems. The British Centurion Mark III tank was one of the first to be equipped with this capability. Over the following decades, stabilization technology was perfected to the point where modern tanks can maintain incredibly steady aim even while moving over rough terrain.

Why Artillery Lagged Behind

Despite these advancements in tank technology, artillery systems remained stationary when firing. There are several reasons for this:

1. Precision Requirements: Artillery systems typically engage targets at much greater ranges than tanks or infantry fighting vehicles. Even small inaccuracies in aim can result in shells missing their targets by hundreds of meters at long ranges.

2. Complexity of Fire Missions: Artillery relies on spotters or drones to call in targets and requires a fire direction center to coordinate trajectories. This complex process is more challenging to manage while on the move.

3. Location Tracking: Accurate artillery fire depends on precise knowledge of the gun's location relative to the target and spotter. This was difficult to maintain while moving.

4. Computational Power: Until recently, fire control systems lacked the computational power and sensors to account for constant vehicle movement and changing terrain.

5. Recoil Management: The massive recoil from large-caliber artillery guns is challenging to manage on a moving platform.

6. Reloading Difficulties: Manually reloading artillery pieces while in motion is extremely challenging.

The RCH1 155: A Game-Changing System

The RCH1 155, or Remote Controlled Howitzer, overcomes these challenges through a combination of advanced technologies and innovative design. Let's explore the key features that make this system so revolutionary.
