US ground forces are enthusiastically pursuing long-range anti-ship weapons to give the US an edge in any fight against China's growing navy.

The Marines want a long-range anti-ship missile "as soon as possible," Gen. Robert Neller, the Marine Corps commandant, told USNI News recently.

The Army is investing heavily in long-range artillery to allow it to pound maritime targets with shells and clear the way for the US Navy.

The US Marine Corps wants a long-range anti-ship missile "as soon as possible," and the Army is right there with it as rival powers like China build up navies to threaten American interests.

"There's a ground component to the maritime fight," Gen. Robert Neller, the Marine Corps commandant, recently told USNI News, adding: "You have to help the ships control sea space. And you can do that from the land."

Neller also said that "you need to have a capability to control the maritime space" and that the Marines needed a long-range anti-ship missile.

"The urgency is just the situation security-wise we find ourselves in the world," he said. "There's a lot of geographical chokepoints, and you know what they are, and the potential adversaries know what they are."

The greatest challenge for the US Navy appears to be in the Pacific, where China is expanding and advancing its navy through the addition of not only more ships but more capable vessels.

A Lockheed Martin representative told Breaking Defense last month that the Marines were exploring shore-based capabilities to meet US Indo-Pacific Command's demands. The Marines have confirmed this, with Brig. Gen. Christian Wortman, the Marine Corps Warfighting Lab commander, saying at a recent conference that the desired anti-ship missile is a "relatively near-term capability that we're making a significant investment" in now.

Likewise, the Army is investing heavily in long-range precision fires with an eye on ensuring the US military can maintain control of the maritime space in a high-end conflict.

The newly established Army Futures Command is looking at fielding the Extended-Range Cannon Artillery, which has a range far greater than existing operational artillery units; Precision Strike Missiles to replace the Army Tactical Missile System; a powerful hypersonic strike weapon; and even a long-range strategic cannon built to hit targets 1,000 miles away.

"You can imagine a scenario where the Navy feels that it cannot get into the South China Sea because of Chinese naval vessels," Secretary of the Army Mark Esper said late last month.

"We can — from a fixed location, on an island or some other place — engage enemy targets, naval targets, at great distances and maintain our standoff and yet open the door, if you will, for naval assets or Marine assets," Esper added.

Shore-based anti-ship systems give enemies another threat to worry about beyond naval vessels and air assets.

US Army Col. Chris Wendland, the commander of the 17th Field Artillery Brigade, told reporters last year after the Army participated in a sinking exercise during the Rim of the Pacific, an exercise that offered insight into how a fight with China might go down, that "what our maritime adversaries conducting this exercise are looking for are other ships or submarines as threats."

"What they are not looking for is the Multi-Domain Task Force, our ground forces, who can acquire the target and fire upon it using land-based surface-to-ship missiles, then be able to move freely," Wendland added.

China, considered the premier threat to US interests, uses similar tactics, having deployed anti-ship cruise missiles across the South China Sea and ballistic missiles believed to have anti-ship capabilities in strategic locations on the mainland.
