Modern Artillery: Why the US Army Needs a New Howitzer

The U.S. Army is at a pivotal moment in its artillery doctrine, confronting the limitations of traditional howitzers and seeking a more mobile, survivable solution.

The Problem with Conventional Howitzers

• M109 Paladin: Must pause to fire, making it vulnerable to radar detection within seconds.
• M777A2 (Stryker units): Towed and unable to keep pace with 60‑mph vehicles; crews require over seven minutes to re-engage after firing.
• HIMARS: Fires rockets in short bursts but at a cost of ~$150,000 per rocket.

These constraints leave the Army exposed to rapid enemy strikes and expensive munitions.

Enter the German RCH 155

A remote‑controlled howitzer that can fire while moving, offering:

• High‑precision tracking: Sensors monitor vehicle position and barrel angle.
• Rapid deployment:
• First round in under 20 seconds when stationary.
• Return to motion in less than 10 seconds.
• Firepower:
• 9 rounds per minute via automated loader.
• Can fire up to five rounds simultaneously, all hitting the target within two seconds—mimicking a HIMARS salvo at lower cost.
• Extended range: 54 km with special munitions, rivaling the M109 and approaching HIMARS’ distance.
• Crew protection: Operated from a protected Boxer chassis, shielding against small‑arms and mines.
• Battery synergy: Six RCH 155s can coordinate to create powerful bursts while maintaining mobility.

Recommendation

The U.S. Army should acquire sufficient RCH 155s for its Stryker Brigade Combat Teams and explore broader adoption across the force, ensuring mobility, survivability, and sustained firepower in future conflicts.
