Biden visits Lockheed plant as weapons stockpile strained

President Joe Biden is visiting a Lockheed Martin plant in Alabama that manufactures an antitank weapons system

TROY, Ala. -- President Joe Biden on Tuesday visited a Lockheed Martin plant that manufactures an antitank weapons system, aiming to herald the U.S.-made arms as a gamechanger for Ukraine’s stiff resistance to Russia's invasion.

But Biden’s visit to the Alabama factory line is also drawing attention to a growing concern as the war drags on: Can the U.S. sustain the cadence in shipping vast amounts of arms to Ukraine while maintaining a healthy stockpile it may need if conflict erupts with North Korea, Iran or elsewhere?

The U.S. has provided at least 7,000 Javelins, including some transferred during the Trump administration, or about one-third of its stockpile, to Ukraine in recent years, according to an analysis by Mark Cancian, a senior adviser with the Center for Strategic and International Studies international security program. The Biden administration says it has committed to sending 5,500 Javelins to Ukraine since the Feb. 24 invasion.

Analysts also estimate that the United States has sent about one-quarter of its stockpile of shoulder-fired Stinger missiles to Ukraine. Raytheon Technologies CEO Greg Hayes told investors last week during a quarterly call that his company, which makes the weapons system, wouldn’t be able to ramp up production until next year, due to parts shortages.
