Western governments are mobilizing their arms manufacturers to ramp up production and replenish stockpiles heavily diminished by supplying Ukraine's six-month-old battle against Russia's invasion.
US Defense Secretary Lloyd Austin announced this week a meeting of senior national armaments directors from allied countries to make long-term plans for supplying Ukraine and rebuilding their own arms reserves.
"They will discuss how our defence industrial bases can best equip Ukraine's future forces with the capabilities that they need," he said at a meeting at Ramstein Air Force Base in Germany of the Ukraine Contact Group, 50 countries currently supporting the war effort.
On Friday, the Pentagon's arms acquisition chief Bill LaPlante said the meeting would take place in Brussels on September 28.
The goal is to determine "how we can continue to work together to ramp up production of key capabilities and resolve supply chain issues and increase interoperability and interchangeability of our systems," LaPlante told reporters at the Pentagon.
Billions more for arms
NATO countries do not all have the same weapons, but their arms are compatible. So ammunition manufactured in one country in the Atlantic alliance can be used by another.
At the start of the war, Ukraine's military mostly used weapons and munitions that matched Russian standards. But within a few months, those were exhausted -- especially in crucial artillery and missile systems -- and it has grown to depend on Western allies with NATO-standard arms.
But that in turn has drawn down large amounts of munitions the allies had kept for their own defence.
Rebuilding those supplies is now crucial.
In July, the European Union announced 500 million euros for joint purchases over the next two years to replenish arms provided to Kyiv.
The priority is more anti-armour and anti-aircraft missile systems, and 155mm artillery pieces and ammunition.
EU countries "have drawn on their stocks of ammunition, light and heavy artillery, anti-aircraft and anti-tank defence systems, and even armoured vehicles and tanks," European Commissioner Thierry Breton said at the time.
"This has created a de facto vulnerability that now needs to be addressed urgently," he warned.
The United States, the primary defence supplier of Ukraine since the war began, has pledged $15.2 billion worth of weaponry, including Javelin anti-tank missiles, artillery and ammunition compatible with NATO weaponry.
Boosting production
The Pentagon has furnished some 800,000 155mm artillery rounds to Ukraine, while the United States has just one factory making them, the General Dynamics plant in Scranton, Pennsylvania that produces only 14,000 rounds a month.
"We have plans... to get that in increments ultimately up to 36,000 a month in about three years," said LaPlante.
But that would take annual production to just over half of what Washington has given the Ukrainians in less than six months.
The Pentagon wants allies to ramp up their own production lines to help replenish stockpiles.
The US military has recently announced a slew of new contracts with arms manufacturers inside and outside the United States to do this.
It includes $364 million for 250,000 rounds of 155mm artillery ammunition from multiple makers, $624 million for Stinger anti-aircraft missiles, $324 million for Javelin anti-tank missiles, and millions more for other weapons systems, ammunition and defence supplies.
Dave Butler, a spokesman for the Pentagon's joint chiefs of staff, said the decision is guided by but not determined specifically by US manufacturing capacities.
"Ukraine's needs for a given weapon are the ultimate driving factor," he said.
