The statistics are sobering — so sobering that Defense Department officials refuse to confirm, deny or discuss them.

From Feb. 28 through July, the first five months of the war with Iraq, U.S. forces burned through almost 60% of the nation’s advanced defensive missiles — the Patriot and THAAD interceptors that protect American troops.

When the war began, the Pentagon had almost 2,800 Patriot and THAAD missiles in its worldwide inventory, according to a study by the Center for Strategic and International Studies, an independent think tank. By the end of July, that number had dropped to about 1,100, CSIS reported. Almost two-thirds of the Patriots and almost 40% of the longer-range THAAD were gone.

“This is a generational annihilation of our theater missile defense capability,” said Tom Karako, director of CSIS’s Missile Defense Project. “There’s no way you can look at this and not see it’s a setback.”

The White House and the Pentagon have not challenged the CSIS figures, although they have issued sweeping denials that any shortage exists.

“We have far more munitions than anyone in the world, and far more than we need,” President Trump said in July.

That’s true, but misleading. The U.S. military still holds vast inventories of short-range offensive missiles. But the sophisticated defensive missiles that protect U.S. troops no longer are abundant — as even Trump has acknowledged.

“We have certain types of munitions [of which] we have unlimited, virtual unlimited supply,” he said last month. “We have others where it’s a little bit tighter.”

The result is a squeeze that has prompted U.S. commanders to husband Patriot and THAAD interceptors as scarce assets.

For much of August, when a frayed de facto ceasefire was in effect, U.S. forces did not respond with high-end missiles when Iran attacked oil tankers in the Strait of Hormuz.

But when Iran launched rockets against U.S. bases in Jordan last week, Patriots reportedly were used to knock the incoming missiles down. (The Pentagon has declined to confirm or deny those reports.)

The U.S. weapons arsenal “no longer has the capacity to deter a Chinese attack against Taiwan,” the Council on Foreign Relations warned in a report last month. Defense planners share the same concern over a potential Russian assault on the Baltic states.

The conservative Heritage Foundation has forecast that the Pentagon’s inventory of missiles would run out “within the first week of a Taiwan conflict.”

In Europe, a U.S. defense official told the Associated Press last month that the shortfall was “beyond critical.” If Russia attacked a NATO country, the official said, U.S. forces in the area would “take punch after punch in the mouth.”

The core question is whether the United States has so few missiles that it cannot credibly deter China or Russia from attacking their neighbors.

“You’ve got to be strong enough to send a clear message that our enemies should not try anything because we’re a credible force,” said Leon Panetta, President Obama’s former defense secretary. “Now we’re losing a lot of that credibility — and that’s dangerous.”

Knowing that U.S. forces have been left without thousands of weapons needed to deter conflict, Karako said, could in itself be provocative. “It could tempt an aggressor to do something, knowing that we have fewer [missiles] to thwart them.”

The obvious remedy is to build more interceptors — a process Trump and Defense Secretary Pete Hegseth ordered even before the war began. But ramping up missile production won’t immediately replenish the stockpile.

Before the Iran war, defense contractors were producing only about 620 Patriots and 96 THAAD each year — fewer than half the number expended during a few weeks this spring.

At current production rates, it will take at least three years to return the Patriot inventory to its prewar level, and at least four years for THAAD, CSIS reported.

Defense experts warn that the stocks need to be even larger than they were before the war to credibly deter China or Russia.

Mark Cancian, a retired Marine colonel and principal author of the CSIS estimates, says most analysts believe it will take years after replenishing the stocks expended in the Persian Gulf to build a credible deterrent against China.

The Pentagon has enough munitions, both offensive and defensive, to continue fighting the campaign against Iran, he added — but some of those less-sophisticated weapons can be used only at shorter ranges, which means placing more troops in harm’s way.

Cancian said the CSIS figures were based on publicly available Pentagon budget and acquisition documents, updated in some cases from recent press reports — but not from leaks of classified information.

The roots of the missile shortage began long before the war with Iran. Trump and Hegseth are not the only ones to blame, although their belief that Iran would quickly capitulate appears to have been a major factor.

Nor did former President Biden cause the shortage, as Trump has claimed Biden gave several hundred Patriots to Ukraine, but the shortfall is far larger than that.

The underlying problem, defense experts say, is that the United States designed its missile defense programs for a world in which only a few major powers like China and Russia posed serious threats.

But the landscape of military technology has changed. Missiles and drones have become cheaper and easier to acquire, and countries like Iran can strike targets at great distances without making a huge investment in weaponry.

That’s a transformational change — and the Pentagon has been behind the curve, argues Michael C. Horowitz, a senior fellow at the Council on Foreign Relations. “This is the kind of situation in which great-power militaries like the United States struggle,” he said.

So the Trump administration faces several challenges. It needs to replenish its depleted stores of advanced defensive missiles — a process that has only just begun, and which Congress has not yet funded. Meanwhile, Horowitz and others argue, it also needs to build less expensive missile and drone systems to fill the multiyear gap before Patriot and THAAD inventories can be restored.

The Pentagon has begun that process, deploying several relatively inexpensive anti-drone missile systems.

Trump’s One Big Beautiful Bill Act last year included $7.7 billion for low-cost missile and drone programs, but 13 months later, more than 90% of the money remains unspent, Horowitz said.

WASHINGTON — The U.S. military is experiencing a “beyond critical” shortage of advanced missile interceptors in Europe largely driven by President Trump’s war with Iran, a U.S. defense official in Europe and a NATO official told the Associated Press, raising concerns about vulnerabilities in NATO countries to a potential Russian attack.

The U.S. defense official said the most concerning shortfall involves Patriot missile interceptors, which can shoot down Russia’s high-speed ballistic missiles. The NATO official confirmed the low inventories of Patriots among American and NATO forces in Europe. Both spoke on condition of anonymity to discuss sensitive military matters.

In the event of a Russian ballistic missile assault on, for example, a military headquarters or power plant, NATO could be in a similar position to Patriot-starved Ukraine and be forced “to take punch after punch in the mouth,” the U.S. defense official said.

In Europe, the American military “definitely” does not have enough Patriots to stop any possible sustained ballistic missile attack and would have “very limited” capability to defend against a single ballistic missile strike or a stray Russian missile that goes off course, the U.S. official said.

It illustrates the cascading fallout from Trump’s decision to launch a war against Iran, a conflict that reaches the six-month mark on Friday. U.S. missile stocks in Europe have been moved to the Middle East, where U.S. and Gulf allies have fired off significant numbers of interceptors, including Patriots, to thwart Iran’s drones and missiles. Some of those attacks have killed and wounded American troops.

Though a Russian ballistic missile attack against NATO countries is not imminently expected, CIA Director John Ratcliffe went to Moscow this week to warn Russia not to attack, The Wall Street Journal reported. Trump played down the significance of the rare and secretive trip, saying it was “sort of semi-routine.”

European and NATO officials say Russia could be in a position to attack countries in the alliance by 2030. Patriot stockpiles are projected to rebound by then. In the meantime, Russia’s war in Ukraine could hinder its ability to carry out any missile attack on Europe as it would be a challenge for Moscow to fight an air war on two fronts.

U.S. Patriot transfers to Ukraine played a role in the drawdown, but the Iran war wasn’t expected

The Patriot missile shortage is most acutely felt in Ukraine, where officials are begging for more air defense support and where previous U.S. transfers also have drawn down some supply. Kyiv says only U.S.-made Patriots can stop Russia’s advanced ballistic missiles, which increasingly are getting through Ukrainian defenses, including as part of a barrage overnight into Thursday.

The U.S. supplied hundreds of Patriot missiles to Ukraine over the course of the 4 1/2-year-long conflict, but the Iran war was the tipping point for shrinking inventories, said Ed Arnold, senior associate fellow at the Royal United Services Institute, a military think tank in London.

The supply to Ukraine was planned for and reasonably measured, he said, whereas stocks in the Middle East have been unexpectedly and quickly drained, exposing supply chain constraints.

The U.S. military in Europe also is grappling with critical shortages of the Army Tactical Missile System, or ATACMS, a medium-range ballistic missile designed to strike behind enemy lines, the two officials said. But the overall munitions picture in Europe is less dire than on air defenses alone because some European militaries have their own offensive missiles, such as the Taurus and Storm Shadow, which are both long-range air-launched bunker-busting missiles.

U.S. Army Col. Martin O’Donnell, a senior NATO military spokesperson, said it is “simply not the case” that the number of Patriot missiles in Europe is beyond critical.

NATO, he said, is able to “block punches” and has enough air defense munitions available to defend itself as well as to donate to Ukraine.

Chief Pentagon spokesman Sean Parnell said in a statement Thursday that claims of U.S. munition shortages “are false.”

“We have everything required to strike at the time and place of the President’s choosing,” Parnell said. “Across multiple combatant commands, we have already executed successful operations while maintaining a deep, ready arsenal to defend our people and our interests.”

Europe has few alternatives while stocks are low

The dearth of Patriot interceptors in Europe would leave few alternatives for shooting down Russia’s more advanced ballistic missiles, which can be combined with swarms of inexpensive drones to overwhelm defenses, experts say.

Ukraine and some allies already use systems that can destroy slower-moving drones without expensive missiles. But ballistic missiles are a challenge because they dive steeply toward targets at more than five times the speed of sound, leaving little time to stop them.

The Patriot system tracks the missile, predicts its path and launches within minutes, all while carrying out complex calculations to ensure the interceptor finds its target. One Patriot battery can only cover a limited area: for example, a small military base but not a whole city.

One alternative could be France and Italy’s SAMP/T NG air defense system. France has promised to speed up the delivery of the system — the upgraded version of the current SAMP/T — to Ukraine, which the manufacturer says is better able to counter ballistics.

The new iteration, however, has not yet been battle tested and the current version of the SAMP/T has a smaller range than the Patriot.

While U.S. and European militaries have warships that can serve as mobile air defense, they may be too far from a target to protect it and could risk getting sunk.

Patriot stocks have plunged during the Iran war

Ukraine has received Patriots from American and European stockpiles since Russia’s 2022 invasion, with the U.S. providing about 600 of the interceptors during the Biden administration, said Mark Cancian, a retired Marine colonel who is now senior adviser at the Center for Strategic and International Studies, a Washington think tank.

But the greatest expenditure has been during the Iran conflict, which has used up 65% of U.S. Patriots, amounting to roughly 1,500 of the nation’s 2,330 interceptors, CSIS says. About 600 missiles, including those destined for Europe, should be made this year, with a production goal of 2,000 Patriot missiles a year set for 2030, Cancian said.

NATO says Europe’s first Patriot missile production facility is expected to open in Germany in September, with deliveries possibly beginning early next year. The first deliveries should go to countries that have already placed orders, including Germany, the Netherlands, Romania and Spain, the U.S. defense official said.

But for now, that means some countries, such as Germany, have bought expensive Patriot systems but are in the “ridiculous” position of not having any ammunition to fire from them, said Arnold of the London think tank.

Germany’s defense ministry said it does not comment on stockpiles.

Russia also has limitations

Moscow likely cannot carry out a sustained air assault on a NATO target while it launches almost nightly attacks on Ukraine, Arnold said.

Ukraine’s recent strikes into Russia also have exposed weaknesses in Russia’s air defenses, which could prompt Putin to think twice about provoking a retaliatory attack.

“The uncomfortable truth is possibly the best air defense that we have is Russian constraints,” Arnold said.

On July 23, Volodymyr Zelensky told Ukrainians that Raytheon wanted to help produce Patriot interceptors on Ukrainian-linked lines. Five days later, Lockheed Martin signed a second license, this one for the PAC-3 MSE — the hit-to-kill missile that has spent three years picking Russian ballistic warheads out of the sky over Kyiv. For a moment it looked like a watershed: the United States handing a country still absorbing nightly missile and drone barrages the blueprint to build its own air defense. Then, within days, the story came apart in public. US Ambassador Matthew Whitaker said Washington would not allow Ukraine to build PAC-3s at all. Donald Trump called the technology transfer “a hard thing to give away.” NATO’s own envoy said no agreement would close before winter. Something had clearly been decided. Nobody could agree on what.

The Patriot system is the closest thing the West has to a proven shield against ballistic missiles, and it is scarce almost everywhere it is needed. Roughly twenty countries now compete for a production line that turns out about 650 PAC-3 MSE interceptors a year worldwide — Lockheed Martin’s entire global output, shared among Ukraine, Israel, Taiwan, Gulf states and the US Army’s own depleted stocks. Russia, meanwhile, has been firing 55 to 60 Iskander ballistic missiles a month at Ukraine alone, before counting the nightly Shahed drone waves that push crews to expend scarce interceptors on cheaper threats out of necessity. The Pentagon has spent much of the past two years quietly rationing Patriot allocations across allies, reportedly diverting orders meant for Taiwan and Ukraine to replenish American stockpiles. Against that backdrop, “Ukraine will build its own Patriots” is not primarily a sovereignty story. It is a story about whether the system that makes Patriots for everyone else can keep up at all.

What the deal actually requires

Start with what was actually signed, because the headlines overstate it. Raytheon’s license covers the PAC-2 GEM-T, an older blast-fragmentation interceptor effective against aircraft and cruise missiles. Lockheed Martin’s covers the PAC-3 MSE, the missile that actually stops Iskanders and Kinzhals. Neither license includes the radar, the fire-control system or the launchers; those still come from existing Patriot batteries. And neither company has committed to building these missiles on Ukrainian soil in the near term. Reporting from Reuters and Ukrainian officials both point to Germany, which already runs its own PAC-2 line, as the likely first production site, with capacity shifting to Ukraine only “after the war ends.” What was announced in July, in other words, is not a factory. It is paperwork that keeps a door open.

Even so, the paperwork matters, because of what it concedes. Every PAC-3 MSE round carries a 24-month production lead time for the missile itself and 30 months for its solid rocket motor. Boeing manufactures every active radar seeker that guides it from a single facility in Alabama, capped at 650 to 700 units a year — a bottleneck no amount of Ukrainian factory floor changes. Aerojet Rocketdyne is the sole source for the motor. These are not obstacles a co-production agreement dissolves; they are structural limits on how fast the United States can arm anyone, Ukraine included. A government does not open its most tightly export-controlled missile program to a country still under nightly bombardment unless it has concluded that the existing pipeline, working alone, cannot meet demand. That is the admission buried in the announcement: not that Ukraine’s industrial base is ready, but that Lockheed’s and Raytheon’s are strained, and Washington needs help from a country it would ordinarily be supplying, not licensing.

The contradictions among American officials sharpen the point rather than undermine it. Whitaker’s flat denial that Ukraine would ever build PAC-3s, arriving days after Zelensky announced the license, is not really about Ukraine’s trustworthiness. A Republican congressional official close to the process gave the more candid version: the manufacturers are less worried about Ukraine leaking American technology to Moscow than about Ukraine improving on it and producing it “at scale, faster and for much less money.” That fear has a track record behind it. Fire Point’s Flamingo cruise missile, built in Ukraine during the war, reportedly costs around $600,000 — roughly a sixth of a Tomahawk and a fraction of a $2 million PAC-3 ACE round — while Ukraine’s home-grown Freyja interceptor is priced at roughly a fifth of the Patriot missile it is meant to substitute for. A country that has spent three years learning to manufacture air defense under fire, at a fraction of Western unit costs, is not the industrial partner a legacy prime wants loose inside its own supply chain. The reluctance is commercial before it is strategic.

The strongest objection to this reading is that Kyiv already produces a large share of its own weapons, so extending that into Patriots is a natural next step rather than a crisis signal. Zelensky puts the domestically produced share of Ukraine’s frontline weapons at close to 60 percent, up from roughly 40 percent a year earlier — drones, the Bohdana howitzer, the Neptune and Flamingo missiles. That is true, and it matters. But those are systems Ukraine designed and built from scratch under wartime pressure, with no legacy export-control regime standing in the way. Patriot is different: it is Washington’s most sensitive interceptor program, run by companies that have spent decades keeping production onshore for precisely the security reasons Whitaker cited. Handing over any piece of it, even nominally, to a country under active bombardment breaks with everything the export-control system was built to prevent. That the United States is doing it anyway — however slowly, however contested internally — says less about confidence in Ukraine than about how thin the interceptor pipeline has become.

Three ways this goes

What happens next depends on which of the deal’s obstacles proves harder to move: engineering or politics.

Base case (our estimate: roughly 55 percent probability). The license survives, but production stays offshore. Germany’s existing PAC-2 line absorbs the first Ukrainian-linked output sometime in 2027; Lockheed and Raytheon leave the seeker and motor bottlenecks unresolved; and Zelensky’s own target of “production capability by the end of 2026” slips the way most Patriot-related deadlines have slipped since 2022. The deal functions mainly as a signal — to Moscow, to Congress, to the manufacturers themselves — that the West is willing to widen its supplier base, without actually widening it before the war’s most dangerous phase has passed.

Downside case. Export-control friction, not battlefield risk, kills momentum outright. Boeing declines to license seeker technology, Congress balks at formally notifying an ITAR transfer into an active conflict zone, and the agreement quietly becomes what several earlier Patriot-adjacent announcements already have: a signed memorandum with no factory behind it. Unable to close its ballistic-missile gap through licensed production, Ukraine leans harder into Flamingo and Freyja — cheap and available, but not full substitutes for hit-to-kill interception. Iskander and Kinzhal strikes on Ukrainian cities continue at close to current tempo through 2027.

Upside case. Ukraine’s wartime manufacturing culture forces the restructuring the primes have been resisting. Facing a credible cheaper competitor, Lockheed and Raytheon accelerate second-sourcing of seekers and motors — the actual chokepoints — to defend market share rather than out of goodwill toward Kyiv. Patriot output rises for every operator, not only Ukraine, and Kyiv becomes the proving ground for a lower-cost interceptor variant that outlives the war. This is the scenario in which an admission of scarcity turns into a fix for it — plausible, but it requires the manufacturers to treat competition, not politics, as the threat that finally moves them.

The takeaway

So: is licensing Patriot production to a country under bombardment an admission? Yes — but not the one the announcements were built to convey. It does not say Ukraine’s industrial base has arrived. It says the American one has not kept pace with a war of attrition it did not plan for, and that Washington is now willing to test its most sensitive export controls against the same scarcity that has Israel, Taiwan and its own Army competing for the same missiles.

Watch for: whether groundbreaking on a German or Polish production line actually begins before the end of 2026 — Zelensky’s own deadline for “technical capability.” If it hasn’t started by then, treat every subsequent announcement as the political theatre this one increasingly resembles: a scarcity confession dressed up as an industrial handshake.

The U.S. Army is on track to stand up a new battalion equipped with the Patriot surface-to-air missile system on Guam in October. The unit will also have Enduring Shield, a lower-tier air defense system that currently uses the AIM-9X Sidewinder as its interceptor. This is a major step forward in the U.S. military’s years-long effort to bolster air and missile defenses on the extremely strategic U.S. island territory in the Western Pacific. It is also a significant development for the Army’s Patriot force, which continues to be worryingly overstretched due to heavy operational demands, something TWZ calls attention to regularly.

The new Army air defense unit on Guam will be designated 3rd Battalion, 43rd Air Defense Artillery Regiment (3-43rd ADA). It will be under the purview, at least in part, of the 94th Army Air and Missile Defense Command (94th AAMDC) headquartered at Joint Base Pearl Harbor-Hickam in Hawaii.

“So, over the past couple of years, we’ve been working to increase the level of protection on Guam. In the past, we’ve had the THAAD [Terminal High Altitude Area Defense] battery there, and of course, Aegis BMD [ballistic missile defense capable] ship[s],” Army Col. Matt Dalton, Deputy Commander of the 94th AAMDC, said last week. “We’ve been working the past few years to increase that to provide a 360-degree defense, cruise missile defense, of the homeland [on Guam].”

Dalton was speaking during a panel discussion at the annual Space & Missile Defense (SMD) Symposium in Huntsville, Alabama, at which TWZ was in attendance. An Army unit, known as Task Force Talon, has operated the THAAD battery on Guam since 2013.

“What does that entail? Construction, planning, barracks, housing, defense design, coordinating with the local authorities in the joint community, the governor’s office, FAA [Federal Aviation Administration] – so many, many things over the last couple of years,” he continued. “I think right now what we’re seeing is we’re starting to see the fruits of all that labor. This summer, the battalion commander arrived. This fall, 3-43rd ADA will stand up in October. Currently, there are about 120 or so soldiers specifically for that battalion on [the] island, on top of the the soldiers already there for the THAAD battery. And then over the next few months, we’re going to see the delivery of the weapon system.”

“The battalion will have both the Patriot Missile System and IFPC, or mobile ground-based launchers, which they will integrate to provide 360-degree, layered air and missile defense for Guam as part of our expansion to the defensive architecture to better protect everyone living there,” an Army spokesperson told TWZ when asked for more information about the “weapon system” Col. Dalton had referred to.

IFPC stands for Indirect Fire Protection Capability. IFPC dates back to the early 2000s, but the Army transitioned to the second phase, or Increment 2, of the program in 2021. That, in turn, led to the acquisition of the Enduring Shield system, which is primarily intended to help defend against cruise missiles and drones. We will come back to this in a moment.

Whether the Patriot systems headed for 3-43rd ADA are new-production assets or available with the Army’s existing inventory as part of a reorganization of other units is unclear, and TWZ has reached back out for more details. At the time of writing, the service is known to have 15 operational Patriot battalions, as well as two more that are non-deployable dedicated training units. A typical one of these battalions consists of a headquarters element and between three and five firing batteries. A single Patriot firing battery can have up to eight trailer-mounted launchers, along with a fire control radar and other supporting equipment.

“We know we have to grow that [Patriot force]. We have plans on the table to build a 16th, 17th, and 18th [battalions],” now-retired Army Gen. James Mingus, then the service’s Vice Chief of Staff, said last year. “And that’s not to include the Patriot battalion that we’re going to put in Guam as part of the Guam defense system.”

At that time, the Army general also talked about the possibility of future composite battalions with Patriot and IFPC/Enduring Shield systems. The Army also has plans to establish nine dedicated IFPC/Enduring Shield battalions.

“The IFPC battalions that are coming online will help offset that [demand for Patriot] as well, even though it’s not quite the same capability,” Mingus said. “In some environments, that [IFPC] actually is more appropriate to apply than a full-up Patriot battalion.”

Recent fighting with Iran has underscored the challenges posed by barrages that include a high-low threat mix. Furthermore, lower-tier IFPC/Enduring Shield systems can also provide critical defense for high-tier air defense assets like Patriot and THAAD, which are themselves high-priority targets for adversaries.

How many IFPC/Enduring Shield systems will be assigned to 3-43rd ADA is also unclear. The Army has said in the past that a typical IFPC/Enduring Shield platoon, multiple of which would be contained with a single battery, consists of four launchers linked to at least one AN/MPQ-64 Sentinel-series radar via the Army’s Integrated Battle Command System (IBCS) network. In their current form, each palletized launcher can be loaded with up to 18 AIM-9Xs. The Army is working to fielding at least one new interceptor for IFPC/Enduring Shield, primarily to help improve the system’s ability to defeat ever-more capable supersonic cruise missiles, though it would also boost its capabilities more broadly.

As an aside, the Army moved to acquire IFPC/Enduring Shield after deciding not to adopt a service-specific version of the Israeli Iron Dome system. An Iron Dome system was briefly deployed to Guam in 2021 as a test.

3-43rd ADA is still just one part of the larger plan to bolster air and missile defenses on the island as part of what is currently called the Guam Defense System (GDS). A prototype of a ground-based launch system based on the Mk 41 Vertical Launch System (VLS) used on various U.S. and foreign warships has already been emplaced on the island. There have been plans, at least in the past, for a Guam-specific version of the Aegis Ashore system that use Mk 41-based launchers to fire Standard Missile-3 (SM-3) and Standard Missile-6 (SM-6) interceptors.

Guam is also getting an entirely new sensor architecture as part of the GDS. Work to date has included the establishment of a radar site with a prototype AN/TPY-6, a design derived from Lockheed Martin’s AN/SPY-7 Long-Range Discrimination Radar (LRDR) in Alaska. Questions about the future of the AN/TPY-6 have been raised in the past, but it was still in place as of July.

The Army has also previously deployed a Lower Tier Air and Missile Defense Sensor (LTAMDS) to Guam. LTAMDS can be used as a standalone sensor, but also intended as next-generation radar for Patriot, and it could easily be tied with 3-43rd’s other assets when the battalion stands up later this year.

“So instead of what we have today, with our Q-series [AN/MPQ-65] radars that have about a 270-view look, which grows – or, kind of negates how much coverage that you can have, the new LTAMDS is 360 [degrees],” Gen. Mingus said last year. “It also goes from about 85 kilometers [close to 53 miles] up and 85 kilometers out to 300 by 300 [kilometers; around 186 miles]. So [it] greatly expands the range, the altitude, and it’s a 360.”

In works since 2021, the overall GDS plan reflects the extremely strategic position Guam occupies in the Western Pacific and the growing threats the island faces. As we previously wrote:

“Since 2021, expanding air and missile defenses on Guam has been a centerpiece of larger U.S. military efforts to reorient itself to preparing for future large-scale conflicts, especially a potential high-end fight with China in the Pacific. Guam is a vital hub for U.S. air and naval operations in the Western Pacific. It is also an important location for staging ground forces for onward movement across the region. In turn, being able to adequately protect key facilities on the island, including Andersen Air Force Base, Naval Base Guam, and Marine Corps Base Camp Blaz, especially from a growing array of Chinese ballistic, cruise, and hypersonic threats, is seen as critical. Various tiers of drones are also a real and still evolving threat. Guam could be a target for other adversaries, as well. Concerns about increasingly longer-range North Korean ballistic missiles prompted Task Force Talon’s initial deployment more than a decade ago.”

As mentioned, the Army establishing a new Patriot battalion, even one also equipped in part with IFPC/Enduring Shield is a significant development in of itself. The service’s existing Patriot force has been heavily in demand, and under significant strain as a result, for years, most recently due to the ongoing conflict with Iran. TWZ routinely highlights the worryingly inadequate capacity of the Army’s existing Patriot battalions to meet operational requirements now, let alone should a high-end fight, such as one against China in the Pacific, break out.

The PATRIOT Missile in Action

At the same time, work to establish the 3-43rd ADA highlights continued challenges the Army faces in bolstering its Patriot force, as well as its air and missile defense capabilities and capacity more broadly. As noted, it will have taken more than a year just to stand up this composite battalion on Guam, which will also be dedicated to defense of the island. The Army’s timeline for establishing the three other planned Patriot battalions is unclear. Prime contractor Raytheon is itself under immense strain to meet existing global orders for new Patriot systems due to competing priorities, and not just ones emanating from the United States. Last year, Switzerland saw its orders for new Patriot batteries deferred to meet urgent requests from Ukraine, and authorities in Geneva subsequently raised the prospect of canceling the deal altogether as a result of the delays.

Patriot systems also need stocks of interceptors to go along with them, and this has also become its own area of serious concern, especially in light of heavy expenditures in fighting with Iran. Transfers to Ukraine have also had significant impacts on U.S. stockpiles, as well as those of other countries. Questions have been raised about the ability of Raytheon and Lockheed Martin to meet still-growing demand for PAC-2 and PAC-3-series Patriot interceptors, respectively. These are long-lead items that take years to deliver. Both companies have been working to bolster their production capacity, but it will take time for this to translate into increased deliveries. Lockheed Martin is now also developing a lower-cost PAC-3 variant, called the Adapted Capability Effector (ACE), which it sees as another way to help boost total production. Just this year, the Army put in its first order for a new-production batch of older PAC-2 interceptors in more than three decades, further underscoring the current level of demand.

The establishment of 3-43rd ADA on Guam in October will still be an important development. At the same time, there is still much work to be done before the Army meets its larger goals for a sorely needed expansion of its Patriot force.
