Why the United States Prefers 155mm Artillery and Its Evolution

The United States military has long relied on the 155mm artillery piece, primarily due to its versatility and effectiveness. The use of this caliber has its roots back to World War I, with the design originally based on a French howitzer.

The Early History of 155mm Artillery

Since its inception, the 155mm artillery piece has stood the test of time. It has been a cornerstone of the US military arsenal, evolving and adapting to meet modern warfare requirements. One of its earliest incarnations was the 8-inch 203mm howitzer, which was phased out in the early 1990s in favor of the more practical 155mm howitzer.

Modern 155mm Howitzers: Evolution and Usage

Currently, the US Army deploys a range of artillery systems, including both the 105mm and 155mm howitzers. The 105mm howitzer is notable for its greater air deployability, making it a more suitable choice for rapid and flexible deployment. However, the 155mm howitzer remains the standard due to its proven capabilities.

The M109 series of howitzers, which includes the M109A6 Paladin and the latest M109A7 version, has been a critical component of US artillery. While the M109 is often mistakenly associated with the Bradley chassis, the M109A7 actually incorporates many components from the Bradley infantry fighting vehicle, such as the engine, transmission, and tracks, enhancing its overall mobility and fire power.

The Versatility of 155mm Artillery

A key factor in the continued use of the 155mm howitzer is its versatility. It can fire effective rounds with a high degree of accuracy, making it a valuable asset in diverse combat scenarios. The 155mm howitzer has been mounted on various chassis, including the M2 Bradley, further enhancing its range and adaptability. This adaptability is crucial in modern warfare, where flexibility is often a deciding factor.

Moreover, the US military possesses a robust and well-stocked inventory of 155mm ammunition, reducing logistical challenges and ensuring reliable support in combat situations.

Conclusion

In summary, the continued use of the 155mm artillery by the United States military is a well-considered choice based on its proven effectiveness, adaptability, and versatility. While other calibers like the 105mm and lighter systems like the M777 have their advantages, the 155mm howitzer remains the standard due to its versatility and the availability of effective ammunition. As the US military continues to evolve, the 155mm artillery will likely remain a crucial component of its arsenal.
