The U.S. is in the final stages of sending almost $570 million in security assistance to Taiwan — the largest such package to date, and one sure to frustrate China — according to multiple congressional aides and a U.S. official.

The administration will use its fastest tool available to deliver the aid: directly shipping its own stocks, a process it’s heavily relied on to support Ukraine’s self-defense. This $567 million package has already received the Pentagon’s approval and is now awaiting the president’s signature.

As it stands, it would be almost double a package of $345 million sent last year. The president will likely approve the tranche before the fiscal year expires at the end of the month, said one aide and an official, who like others speaking for this story were not permitted to talk to the press and were granted anonymity.

The new package of aid has not been previously reported.

Taiwan is by far the most delicate issue in America’s relationship with China. Beijing maintains the democratically governed island is part of its rightful territory, and won’t rule out military force to one day unite with it. The U.S., meanwhile, is Taiwan’s oldest and largest supplier of military aid.

The impasse often leads to public displays of frustration. At this year’s Shangri-La Dialogue, Asia’s largest defense summit, China’s Minister of National Defense Adm. Dong Jun warned that supporters of Taiwanese “separatists” would be punished — shortly after China’s military held large drills around the island.

And in a briefing this week, a spokesperson for China’s Ministry of Foreign Affairs condemned U.S. military support, arguing it “sends a wrong message to ‘Taiwan independence’ separatist forces.”

Still, at a September defense conference hosted in Beijing, which a top Pentagon official for China attended, members of the People’s Liberation Army were gentler. The month before, U.S. National Security Advisor Jake Sullivan also traveled to China, where he met with senior members of the government and helped schedule a long-sought call between America’s top military leader in the region and his Chinese counterpart.

The security assistance will fund training, stockpiles, anti-armor weapons, air defense and multi-domain awareness, according to a U.S. official, who would not be more specific. It will also include drones, which are key to America and Taiwan’s “asymmetric” strategy to defend the island against China’s much larger military.

The ambiguity is typical for aid to Taiwan, which the U.S. rarely discusses in detail due to its sensitivity. Neither the Pentagon nor the National Security Council would comment for this story, except to say that America maintains the right to support Taiwan’s self-defense, per longstanding government policy.

“We have no comment on this matter. Taiwan will continue to enhance defense capabilities and closely work with the United States so as to actively uphold peace, stability and prosperity across the Taiwan Strait and in the Indo-Pacific region,” a spokesperson for Taiwan’s unofficial embassy in Washington said in a statement.

In an effort to hasten support for Taiwan, Congress gave the administration the authority to send Taiwan up to $1 billion in its own stocks each year — a more direct show of support than previous assistance from arms sales. That said, lawmakers didn’t give the Pentagon an actual budget, and the department has been loathe to send equipment it can’t replace.

After debating a further package of aid last year — one supported by members of the State Department and White House — Secretary of Defense Lloyd Austin paused any further aid to Taiwan without funding.

That money arrived in April, when Congress included $1.9 billion to replenish U.S. stocks sent to countries in the Indo-Pacific. Leaders across the Pentagon have since been planning how to use that funding, most of which will go to Taiwan.

The package now close to approval went through several rounds of revisions, according to multiple officials. The Pentagon initially planned a smaller amount, but in a meeting of different parts of the administration this summer, multiple senior officials said it needed to be far larger — leading to the expanded $567 million figure.

The Pentagon is also now working on a third package of drawdown aid to Taiwan, which the government plans to complete by the end of the administration in January, the U.S. official said.

The April bill featured a further $2 billion in longer-term security aid for the region, $1.4 billion of which went to Taiwan in a separate package approved — though never announced — this summer. The U.S. green-lit the sale of $228 million in repairs and spare parts for military kit this week, adding to the $19 billion in such foreign military sales Taiwan is waiting on for delivery.

A Pentagon watchdog recently published a scathing report on the first round of support last year. It found that shipping issues caused by the American military led to aid arriving in Taiwan later than expected, covered in mold and in some cases expired. Fixing the issues cost the two sides a further $730,000.

“More broadly, the delivery of non-mission-capable items inhibits the [Defense Department’s] ability to achieve established security cooperation goals and may lead to loss of partner confidence in the United States,” the report said.

The U.S. Air Force’s newest bomber is officially getting two additional homes.

Air Force Secretary Frank Kendall approved basing locations for the B-21 Raider at Whiteman Air Force Base, Missouri, and Dyess Air Force Base, Texas, the service announced Friday.

The Air Force previously selected Ellsworth Air Force Base, South Dakota, as the B-21 Raider’s first base.

The aircraft, which is the first bomber the Air Force has introduced since the Cold War, is intended to become the “backbone of the Air Force’s flexible global strike capability,” according to the Air Force. Developed by Northrop Grumman, the stealth bomber will come equipped with nuclear capabilities, as well as regular munitions, and be able to assist with manned and unmanned operations.

The B-21 Raider made its first test flight Nov. 10, 2023, out of Air Force Plant 42 in Palmdale, California.

“We continue to achieve B-21 production milestones; through digital engineering and open architecture design, we are getting an agile strategic deterrent that delivers a decisive response as required,” said Gen. Thomas Bussiere, Air Force Global Strike Command commander, in a release.

The Air Force released the first video of the B-21 in flight Wednesday.

Airmen and defense industry representatives discussed the B-21 program’s progress this week at the Air and Space Force Association’s Air, Space and Cyber Conference in National Harbor, Maryland.

Thomas Jones, sector president of Northrop Grumman Aeronautics Systems, said the program was conducting two flight test flights “in a given week” in preparation for the B-21 Raider’s life as a daily flyer.

The Air Force anticipates purchasing at least 100 B-21s, which will replace the B-1 Lancer and B-2 Spirit bombers.

NATIONAL HARBOR, Maryland — Air Force Special Operations Command has returned about 60% of its CV-22 Osprey fleet to fully operational flight status and expects to once again deploy the tilt-rotor aircraft to support combatant commands in a matter of weeks.

In a roundtable with reporters at the Air and Space Forces Association’s Air Space Cyber conference, AFSOC commander Lt. Gen. Michael Conley said the command is clearing about three Ospreys for flight operations every 10 days as it gradually lifts the fleet’s grounding.

AFSOC has roughly 50 CV-22s, and expects to have all its Ospreys back to normal flying operations by late 2024 or early 2025. Conley would not say where Ospreys are likely to deploy.

The military in December 2023 grounded all its V-22s, which are flown by AFSOC, the Navy and the Marine Corps, following the fatal crash of an Air Force Osprey off the coast of Japan a week earlier. That crash killed all eight crew members aboard.

An Air Force investigation later found the crash was caused in part by cracks in a crucial gear driving the tilt-rotor aircraft’s proprotors, and also by the pilot’s decision not to land the aircraft after multiple alerts known as “chip burn warnings” sounded in the aircraft. Those alerts let Osprey air crews know when metal flakes are starting to come off of its gears, which can be a sign the aircraft is stressed.

After a three-month grounding, the Pentagon announced it would start to return its Osprey fleet to flight operations, after revising training for troops flying them and changing maintenance procedures. There were no equipment modifications instituted as a prerequisite for returning the aircraft to flight.

AFSOC put new operating guidance in place earlier this year to require Osprey pilots to land sooner when chip burn warnings go off, Conley said. Now, Osprey air crews are instructed to land as soon as practical after the first warning sounds, and after a second, land as soon as possible.

Pilots always have discretion to fly their aircraft the way they think it requires, Conley said, since each flight has its own unique circumstances. But the tighter guidance on landing is meant to “make it less ambiguous to the crews” to decide what they should do in dangerous situations.

AFSOC had to quickly requalify its Osprey instructors and evaluators before it could start retraining air crew members, Conley said.

And Conley said AFSOC has been “very deliberate and slow and methodical” as it goes through its Osprey fleet one by one, and paying particular attention to aircraft parts.

Naval Air Systems Command Boss Vice Adm. Carl Chebi, who oversees the military’s Osprey program, told lawmakers in June that the entire V-22 fleet would likely not be back to normal flight operations until at least mid-2025.

U.S. Special Operations Command cut its desired purchase of 75 armed overwatch aircraft to 62 following a recommendation last year from a government watchdog to slow down the program’s acquisition.

Now, in a recent update to its recommendation, the Government Accountability Office noted that while the number of requested aircraft had been reduced, U.S. Air Force Special Operations Command, or AFSOC, officials still hadn’t justified why they need that many aircraft.

The armed overwatch program aims to field fixed-wing aircraft for AFSOC to deploy to austere locations, Defense News previously reported. The current aircraft at the program’s center is the AT-802U Sky Warden, a single-engine, two-person platform made by L3Harris Technologies and Air Tractor.

The command expected to spend $2.2 billion to buy the originally requested 75 aircraft, which replaces the U-28 Draco.

SOCOM had purchased 16 Sky Wardens as of last year, with plans to purchase another dozen this year, Defense News reported.

The most recent update, published Sept. 5, notes SOCOM has plans to divest two of its intelligence, surveillance and reconnaissance, or ISR, platforms. However, those platforms were used to support armed overwatch.

The watchdog “found that SOCOM has not taken steps to plan for, or add, critical ISR capabilities provided by soon-to-be divested aircraft,” according to the GAO report.

SOCOM also failed to address risks associated with losing those capabilities if the new armed overwatch aircraft didn’t have them as part of the platform’s fielding, the report found.

The armed overwatch program’s austere mission means that developers must provide an aircraft with minimal logistics and support needs.

The aircraft itself must be able to give ground troops close air support, precision strike and ISR capabilities, according to the report. It’s primarily expected to be used in such roles in counterterrorism and irregular warfare missions, according to program information.

The GAO report stated SOCOM “concurred” or “partially concurred” with its six major recommendations.

Those recommendations included reevaluating the number of aircraft needed; limiting procurement to the minimum needed for testing until the fleet size is determined; assessing risks to missions if the ISR capabilities are not added; identify challenges to operate and deploy the aircraft; and assess whether the program remains an affordable priority; and update concepts for the types of operations the aircraft might conduct.

Fiscal 2026 is marked in the GAO report as a key year for deadlines such as completing the operational test and evaluation, making a full rate production decision and reaching initial operational capability.

The U.S. Air Force began a capability assessment in 2017 to evaluate potential light attack aerial platforms for use with coalition partners. At the time, then-Air Force Secretary Heather Wilson told Congress that the purpose was to free up more advanced and costly assets for other tasks.

Wilson cited an example of F-22 fighter jets being used to strike a drug laboratory in Afghanistan — a mission that could have been accomplished with a less sophisticated platform at a lower cost.

After a series of experiments, the program transferred to SOCOM. In 2021, the command filed its request for 75 aircraft, according to a Congressional Research Services report.

The per-hour operating cost of an aircraft like the Sky Warden is about 2% to 4% of that of advanced fighters, the report noted.

Nearly $6 billion in U.S. funding for aid to Ukraine will expire at the end of the month unless Congress acts to extend the Pentagon’s authority to send weapons from its stockpile to Kyiv, according to U.S. officials.

U.S. officials said the Biden administration has asked Congress to include the funding authority in any continuing resolution lawmakers may manage to pass before the end of the fiscal year on Sept. 30 in order to fund the federal government and prevent a shutdown. Officials said they hope to have the authority extended for another year.

They also said the Defense Department is looking into other options if that effort fails.

The officials, who spoke on condition of anonymity to discuss the funding talks, did not provide details on the options. But they said about $5.8 billion in presidential drawdown authority, or PDA, will expire. Another $100 million in PDA does not expire at the end of the month, the officials said. The PDA allows the Pentagon to take weapons off the shelves and send them quickly to Ukraine.

They said there is a little more than $4 billion available in longer-term funding through the Ukraine Security Assistance Initiative that will not expire at the end of the month. That money, which expires Sept. 30, 2025, is used to pay for weapons contracts that would not be delivered for a year or more.

Gen. CQ Brown, chairman of the Joint Chiefs of Staff, said Thursday that as the Defense Department comptroller provides options to senior defense and military service leaders, they will look at ways they can tap the PDA and USAI funding.

He said it could be important to Ukraine as it prepares for the winter fight.

“One of the areas that we could do work with them on … is air defense capabilities and the ability to defend their critical infrastructure,” Brown told reporters traveling with him to meetings in Europe. “It’s very important to Ukraine on how they defend their national infrastructure, but also set their defenses for the winter so they can slow down any type of Russian advance during the winter months.”

Earlier Thursday at the Pentagon, Maj. Gen. Pat Ryder, the press secretary, noted that the PDA gives the Pentagon the ability to spend money from its budget to send military aid to Ukraine. Funding in the $61 billion supplemental bill for Ukraine passed in April can reimburse the department for the weapons it sends.

“Right now, we’re continuing to work with Congress to see about getting those authorities extended to enable us to continue to do drawdown packages,” said Ryder. “In the meantime, you’re going to continue to see drawdown packages. But we’ll have much more to provide on that in the near future.”

The U.S. has routinely announced new drawdown packages — often two to three a month.

Failure by lawmakers to act on the PDA funding could once again deliver a serious setback in Ukraine’s battle against Russia, just five months after a bitterly divided Congress finally overcame a long and devastating gridlock and approved new Ukraine funding.

Delays in passing that $61 billion for Ukraine earlier this year triggered dire battlefield conditions as Ukrainian forces ran low on munitions and Russian forces were able to make gains. Officials have blamed the monthslong deadlocked Congress for Russia’s ability to take more territory.

Since funding began again, U.S. weapons have flowed into Ukraine, bolstering the forces and aiding Kyiv’s incursion into Russia’s Kursk region. Ukraine’s forces stormed across the border five weeks ago and put Russian territory under foreign occupation for the first time since World War II.
