How Ukraine war has shaped planning for a China conflict

WASHINGTON >> As the war rages on in Ukraine, the United States is doing more than supporting an ally. It's learning lessons — with an eye toward a possible clash with China.

No one knows what the next U.S. major military conflict will be or whether the U.S. will send troops — as it did in Afghanistan and Iraq — or provide vast amounts of aid and expertise, as it has done with Ukraine.

But China remains America's biggest concern. U.S. military officials say Beijing wants to be ready to invade the self-governing island of Taiwan by 2027, and the U.S. remains the island democracy's chief ally and supplier of defense weapons.

While there are key differences in geography and in U.S. commitment to come to Taiwan's defense, “there are clear parallels between the Russian invasion of Ukraine and a possible Chinese attack on Taiwan,” a Center for Strategic and International Studies report found last month.

A look at some of the lessons from the Ukraine war and how they could apply to a Taiwan conflict:

Arm in advance

Soon after Russian troops crossed into Ukraine last February, the U.S. and allies began sending massive amounts of weapons across the border from partner nations.

But Taiwan would need to be fully armed in advance, CSIS found in dozens of war scenarios it ran for its report.

“The `Ukraine model' cannot be replicated in Taiwan because China can isolate the island for weeks or even months,” CSIS found. “Taiwan must start the war with everything it needs.”

Deputy Secretary of Defense Kathleen Hicks said Ukraine “was more of a cold-start approach than the planned approach we have been working on for Taiwan, and we will apply those lessons.”

Hicks told The Associated Press that an amphibious landing is the hardest military operation to undertake. And re-supply will be difficult, particularly if China chokes off ocean access.

Stockpile woes

But the Pentagon can't pre-position equipment it doesn't have. Ukraine is putting intense pressure on the U.S. and European defense stockpiles and exposing that neither was ready for a major conventional conflict.

For some items “we have weaknesses in both our inventory and our production capacity,” said CSIS International Security Program senior adviser Mark Cancian, an author of the Taiwan report. “In a couple of places, particularly artillery ammunition, it could become a crisis,” he said.

Ukraine is shooting as many as 7,000 rounds a day to defend itself and has depended on announcements about every two weeks of new ammunition shipments from the U.S.

Since Russia invaded, the U.S. has sent Ukraine millions of rounds of munitions, including small arms and artillery rounds, 8,500 Javelin anti-armor systems, 1,600 Stinger anti-aircraft systems and 100,000 rounds of 125mm tank ammunition.

One of the biggest stockpile pressure points has been 155mm howitzer ammunition. The U.S. has sent Ukraine 160 howitzers and more than 1 million howitzer rounds, which have been put to heavy use with as many as 3,000 rounds fired a day, according to the Pentagon.

Ukraine is waging a different type of war than the U.S. would likely face with China, said Doug Bush, assistant secretary of the Army for acquisition. A future U.S. campaign would likely involve much more airpower and seapower, taking some of the pressure off land-based systems and ammunition.

But allies would still need to be supported with landbased systems and ammunition.

Rebuilding takes time

The Pentagon's defense strategy says the U.S. must be able to conduct one war while deterring another, but the supply chain has not reflected that.

Hicks said the surge of weapons to Ukraine “has not slowed down U.S. support to Taiwan,” but many of the military sales promised to Taiwan are facing the same pressures the Ukraine munitions face, such as limited parts or workforce issues.

In response, the U.S. has set up a presidential drawdown authority for Taiwan, Hicks said, which will allow the U.S. to send weapons from its own stockpiles instead of arranging new contracts.

The Army is working with Congress to get the authority to do multiyear contracts, so that firms will invest to meet longerterm needs, especially for the systems Bush called “the big four” — Javelin missiles, High Mobility Artillery Rocket System (HIMARS) launchers, Guided Multiple Launch Rocket System (GMLRS) munitions and 155mm rounds.

“Without that urgency, we risk being behind at the wrong time later,” Bush said.

The Army is adding production lines for 155mm artillery — including major components such as the outer metal shell, chargers, the fuse and the explosive material — while right now all production is at one facility in Iowa.

All of that will take time. CSIS reported it could take five years or more to replenish 155mm, Javelin and Stinger stockpiles.

“The good news is that I think the Ukraine conflict has alerted people to these weaknesses. The bad news is that they're going to take a long, long time to solve even if there is a lot of political will,” said Hal Brands, a senior fellow at the American Enterprise Institute.

For European stockpiles, there's not much excess left to send, and many of the partner nations are rushing to sign new contracts with industry to replenish inventories. However, NATO SecretaryGeneral Jens Stoltenberg warned this week in Brussels that particularly for larger caliber munitions, such as for ground artillery, it could be as long as 2 1/2 years before some new orders are delivered.
