Analysis: 155mm Wheeled Mobile Howitzers Could Become Anti-Ship Artillery - Naval News
The concept of 155mm tracked Self-Propelled Howitzers (SPHs) acting as mobile coastal artillery isn’t particularly new; however, the reality of implementing this concept recently got much better with new advances in GPS precision-guided rocket-assisted projectiles and Hypervelocity shell technology.

SPHs, and wheeled mobile howitzers, having a high rate-of-fire, fully automatic ammunition loading; automatic traverse, elevation, and firing; and short emplacement and displacement times, 155mm mobile howitzers have finally advanced to the point of achieving a good hit percentage against a moving target, large or small. Thus, land armies are giving renewed attention to these fast moving wheeled 155mm mobile artillery systems that could also transition interest towards the Marines.
Most land armies envision using Long-Range Precision Fires (LRPF) missiles and Land Based Anti-Ship Missiles (LBASM) to attack surface warships out from a few dozen to a few hundred miles since LRPFs and LBASMs have the best chance of ensuring a hit, and the missiles’ long range can deter enemy warship encroachment. Very large Tactical Ballistic Anti-Ship missiles, especially those on Chinese and Russian Transporter Erector Launcher (TEL) trucks, can range out to over 1,000 miles (1,609 km) and provide effective deterrence over-the-horizon, keeping naval forces at a distance. Due to the limited number of mounted missiles per truck launcher, deterrence by a few coastal LBASMs can keep some enemy warships at a distance; however, the lack of quantities of LBASM trucks and their reloading support trucks means that LBASM trucks might be hard-pressed to stop a determined large-sized amphibious invasion force once all the missiles are expended.
Thus, 155mm SPHs or wheeled mobile howitzers acting as coastal artillery batteries start to appeal to land armies because a single 155mm mobile howitzer can carry around 20 to 40 155mm precision-guided munitions compared to a Multiple Launch Rocket System (MLRS) truck firing anywhere from two to twelve or more guided precision LBASMs. Quantity of ammunition has a quality deterrence all its own.
