Senior Army and Pentagon strategists and planners are considering ways to fire existing weapons platforms in new ways around the globe – including the possible placement of mobile artillery units in areas of the South China Sea to, if necessary, function as air-defense weapons to knock incoming rockets and cruise missiles out of the sky, senior Pentagon and Army officials told Scout Warrior.
Adm. Harry Harris, the commander of U.S. Pacific Command, has said he thinks the U.S. should think about new ways of using land-based rockets and howitzer systems as offensive and defensive weapons in areas of the South China Sea.
Such a move would better ensure access and maneuverability for U.S. and allied ships, assets and weapons in contested or tense areas, he explained.
Howitzers or Paladins could be used as a mobile, direct countermeasures to incoming rockets, he said. A key advantage to using a Paladin is that it is a mobile platform which could adjust to moving or fast-changing approaching enemy fire.
“We could use existing Howitzers and that type of munition (155m shells) to knock out incoming threats when people try to hit us from the air at long ranges using rockets and cruise missiles,” a senior Army official told Scout Warrior in an interview.
This consideration comes not long after Pentagon officials confirmed that satellite pictures show the Chinese have placed weapons such as Surface to Air Missiles in areas of the South China Sea.
Having land-based rockets or artillery could give US and allied forces both strategic and tactical assistance.
“A Howitzer can go where it has to go. It is a way of changing an offensive weapon and using it in dual capacity,” the official explained. “This opens the door to opportunities and options we have not had before with mobile defensive platforms and offensive capabilities."
Mobile air defenses such as an Army M777 or Paladin Howitzer weapon could use precision rounds and advancing fire-control technology to destroy threatening air assets such as enemy aircraft, drones or incoming artillery fire.
Alongside the South China Sea, more mobile artillery weapons used for air defense could also prove useful in areas such as the Middle East and Eastern Europe, officials said. Having mobile counter-air weapons such as the M109 Paladin, able to fire 155m precision rounds on-the-move, could prove to be an effective air-defense deterrent against Russian missiles, aircraft and rockets in Eastern Europe, the senior Army official told Scout Warrior.
Regarding the South China Sea, the U.S. has a nuanced or complicated relationship with China involving both rivalry and cooperation; the recent Chinese move to put surface-to-air missiles and fighter jets on claimed territory in the South China Sea has escalated tensions and led Pentagon planners to consider various options.
Officials are clear to emphasize that no decisions have been made along these lines, yet it is one of the things being considered. Pentagon officials have opposed further militarization of the area and emphasized that the territorial disputes in the South China Sea need to be resolved peacefully and diplomatically.
At the same time, Pentagon officials have publicly stated the U.S. will continue “freedom of navigation” exercises wherein Navy ships sail within 12 miles of territory claimed by the Chinese - and tensions are clearly on the rise. In addition to these activities, it is entirely possible the U.S. could also find ways to deploy more offensive and defensive weapons to the region.
Naturally, a move of this kind would need to involve close coordination with U.S. allies in the region, as the U.S. claims no territory in the South China Sea. However, this would involve the deployment of a weapons system which has historically been used for offensive attacks on land. The effort could use an M777 Howitzer or Paladin, weapons able to fire 155m rounds.
They would bring a mobile tactical advantage to existing Army air defenses such as the Patriot and Theater High Altitude Area Defense, or THAAD, which primarily function as fixed-defense locations, the senior Army official said.
The M777 artillery weapon, often used over the years in Iraq and Afghanistan, can fire the precision GPS-guided Excalibur artillery round able to destroy targets within one meter from up to 30-kilometers or more away. Naturally, given this technology, it could potentially be applied as an air-defense weapon as well.
Using a Howitzer or Paladin could also decrease expenses, officials said.

“Can a munition itself be cheaper so we are not making million dollar missiles to shoot down $100,000 dollar incoming weapons,” the Army official said.
While Pentagon officials have not formally confirmed the prospect of working with allies to place weapons, such as Howitzers, in the South China Sea, they did say the U.S. was stepping up its coordination with allies in the region.
Strategic Capabilities Office
The potential use of existing weapons in new ways is entirely consistent with an existing Pentagon office which was, for the first time, recently announced publicly. It is called the Strategic Capabilities Office, or SCO, stood up to look at integrating innovating technologies with existing weapons platforms – or simply adapting or modifying existing weapons for a wider range of applications.
“I created the SCO in 2012 when I was deputy secretary of defense to help us to re-imagine existing DOD and intelligence community and commercial systems by giving them new roles and game-changing capabilities to confound potential enemies -- the emphasis here was on rapidity of fielding, not 10 and 15-year programs. Getting stuff in the field quickly,” Carter said.
Senior Army officials say the SCO office is a key part of what provides the conceptual framework for the ongoing considerations of placing new weaponry in different locations throughout the Pacific theater. An Army consideration to place Paladin artillery weapons in the South China Sea would be one example of how to execute this strategic framework.
In fact, the Pentagon is vigorously stepping up its support to allies in the Pacific theater. A 2016 defense law, called the Southeast Asia Maritme Security Initiative, provides new funding to authorize a Department of Defense effort to train, equip, and provide other support to the Philippines, Vietnam, Indonesia, Malaysia, and Thailand, Urban explained.
"The Secretary (Secretary of Defense Ashton Carter) has committed $425M over Fiscal Years 2016-2020 for MSI (Maritime Security Initiative), with an initial investment of $50M available in fiscal year 2016 toward this effort," a Pentagon official said.
Army Rebalance to the Pacific
While the Army is naturally immersed in activities with NATO to deter Russian movements in Eastern Europe and maintaining missions in Iraq and Afghanistan – the service has not forsaken its commitment to pursuing a substantial Army component to the Pentagon’s Pacific rebalance.
Among other things, this involves stepped up military-to-military activities with allies in the region, coordinating with other leaders and land armies, and efforts to move or re-posture some weapons in the area.“The re-balance to the Pacific is more than military, it is an economic question. the Army has its hands full with the Middle East and with Europe and is dealing with a resurgent problem in Europe and North Africa,” an Army official said. “We have been able to cycle multiple units through different countries,” the senior official said.
Also, the pentagon has made the Commander of Army Pacific a 4-star General, a move which enables him to have direct one-to-one correspondence with his Chinese counterpart and other leaders in the region, he added.
As of several years ago, the Army had 18,500 Soldier stationed in Korea, 2,400 in Japan, 2,000 in Guam, 480 in the Philippines, 22,300 in Hawaii and 13,500 in Alaska. The service continues to support the national defense strategy by strengthening partnerships with existing allies in the region and conduction numerous joint exercises, service officials said.
“The ground element of the Pacific rebalance is important to ensure the stability in the region," senior officials have said. Many of the world's largest ground armies are based in the Pacific.
Also, in recent years Army documents have emphasized the need for the service to increase fire power in the Pacific to increased fielding of THAAD, Patriot and the Army Tactical Missile System, or ATACMS in the Pacific region. ATACMS is a technology which delivers precision fires against stationary or slow-moving targets at ranges up to 300 km., Army officials have said. In 2013, the Army did deploy THAAD missile systems to Guam.
Army officials have also called for the development of a land-based anti-ship ballistic missile, directed energy capability, and additional land-based anti-ship fires capabilities such as the Guided Multiple Launch Rocket System.
Army officials have also said man support a potential adaptation of the RGM-84 Harpoon and calls for the development of boost-glide entry warheads able to deploy “to hold adversary shipping at risk all without ever striking targets inland.
Boost-glide weapons use rocket-boosted payload delivery vehicles that glide at hypersonic speeds in the atmosphere. An increase in the Army’s investment in boost-glide technology now could fast track the Army’s impact in the Air-Sea Battle fight in the near term, Army papers have stated.
