- USS Milius passes Mischief Reef in FoN Image
The USS Nimitz (CVN-68) Carrier Strike Group is underway in the Philippine Sea, reportedly operating East of Taiwan, after completing a large anti-submarine warfare exercise with the South Korean & Japanese navies on April 4.
The Makin Island (LHD-8) Amphibious Ready Group (ARG) is now operating in the South China Sea, ~West of Manila. It transited over the past week from Busan, South Korea, for planned exercises with the Philippines navy.
The USS Milius (DDG-69), a guided-missile destroyer, passed within 12 nautical miles of China’s Mischief Reef artificial island installation & military infrastructure, which lies in the Philippines’ Economic Zone (and also claimed by Vietnam & Taiwan).
The USS Carl Vinson (CVN-70) Carrier Strike Group is underway in the Eastern Pacific, conducting drills in preparation for an upcoming deployment. One week ago, it was operating outside Naval Base San Diego.

The CSG completed its ratings & will join 7th Fleet operations as CSG1. ImageImage
According to open source intelligence, the US Navy was operating at least two P-8 “Poseidon” Maritime Patrol & Anti-Submarine Aircraft and one USAF RC-135V “Rivet Joint” Signal Intelligence Platform off the Southern and Eastern coasts of Taiwan.
A US Marine Corps Cessna UC-35, used for the “Time Sensitive Shipment” of Personnel & Cargo left Okinawa, Japan headed Southwest towards the Philippines.

“From April 11-28, 17K members of the Philippines and US military will participate in an annual bilateral exercise.”
The PLAN’s CNS Shandong (17) Carrier Strike Group transited the Bashi Channel & has been operating off of Taiwan’s East coast.

The Nimitz CSG is also nearby in the vicinity of Taiwan. Two defense officials told USNI there have been no reported unsafe interactions. Image
The USS Ronald Reagan (CVN-76) CSG, the only forward deployed aircraft carrier group, remains in port in Yokosuka, Japan.

The USS America (LHA-6) Amphibious Ready Group (ARG) is in Sasebo, Japan.
The map below shows PLAN activity as part of the Eastern Theatre Command’s “Joint Sword” drills from April 8-10.

As of Monday, there were 12 PLAN warships and more than 90 aircraft operating in the vicinity of Taiwan, according to officials in Taipei.
The Makin Island ARG—with the 13th Marine Expeditionary Unit embarked—is operating in the SCS ahead of this week’s Balikatan exercise.

17K personnel will train together for maritime security, amphibious operations, live-fire training, & more—a marked expansion from 9K in 2022. Image

Notable developments in the Indo-Pacific last week:

- China conducted back-to-back joint combat patrols 24nm from Taiwan on the same day for the first time
- 59 PLA aircraft detected around Taiwan + 43 entered its ADIZ on Monday, largest single-day surge of 2025 + highest in 5 months
- Recent PLA military drills in the Taiwan Strait, Western Pacific, South China Sea, East China Sea, + Yellow/Bohai Sea
- New Shuiqiao landing barges carrying out docking trials with civil-military RO-RO ferries
- Elevated PLA drone activity, including WZ-10 + GJ-2

Taiwan recently wrapped up a week of “Rapid Response Exercises,” practicing tactical maneuvers, key asset protection, concealment, and cover operations to enhance readiness and response capabilities. MND said: “ROC Armed Forces closely monitor maritime and aerial activities, conducting joint operations to track and respond to PLA incursions.”

China’s foreign ministry stated: “China’s relevant military operation is necessary, lawful and legitimate in order to defend national sovereignty, security and territorial integrity. It’s a firm response to external forces who are hellbent on abetting and aiding ‘Taiwan independence,’ and a warning to ‘Taiwan independence’ separatist forces’ unconscionable acts... Those who attempt to use Taiwan to contain China will get burned for playing with fire.”

“...this newest logistics capability is further evidence of the PLA’s efforts to meet Chairman Xi Jinping’s reported mandate to have military capabilities necessary to conduct a large-scale invasion of Taiwan by 2027.” @tshugart3 @ChinaMaritime Image
“The new Shuiqiao LPUs offer the PLA a critical capability and fulfill a long-sought requirement to reliably deliver a large volume of second echelon forces into amphibious landing areas. In the context of other developments that include improvements to amphibious base infrastructure, the increased use of a diverse array of civilian vessels to support amphibious operations, and other PLA capability developments, the Shuiqiao LPUs are another example of the PLA significantly increasing capabilities to conduct a large-scale cross-strait operation—if they are ordered to do so—in coming years.”
May already be testing the new landing barges with a “civilian” PLA-associated roll-on, roll-off (RO-RO) ferry:

Many rumors circulating about U.S. aircraft carriers.

Here’s an update on all 11 🇺🇸

• 3x deployed: Truman in Red Sea, Vinson in WESTPAC, Washington forward in Japan
• 4x active/available: Ford completing COMPTUEX in the Atlantic, Lincoln & Roosevelt in San Diego, Nimitz in Bremerton
• 1x sea trials: Bush in the Atlantic
• 3x maintenance: Reagan in Puget Sound, Ike in Norfolk, Stennis in Newport News

American carriers frequently conduct routine operations off the coast of the U.S. - just because one leaves port does not mean it’s on deployment.

Ford is next up on the east coast but must first complete COMPTUEX training, & Nimitz has been conducting pre-deployment training off the west coast.

Senior U.S. officials @__CJohnston__ spoke with expect a deployment extension for Truman in CENTCOM. There is precedent to move a CSG from the Indo-Pacific to the Middle East, so Vinson could be sent in that direction if need be. In a surge scenario, Roosevelt & Lincoln are also available.

At this time, the U.S. Navy has not announced any new deployments. More info & sources below.Image
The Harry S. Truman Carrier Strike Group (HSTCSG) is in the Red Sea currently conducting its 3rd day of strike operations against the Iranian-backed Houthi in Yemen.
Truman’s deployment will likely be extended, @__CJohnston__ reported today.

🚨 The U.S. launched large-scale precision strikes against the Houthi in Yemen yesterday: Map

The Harry S. Truman Carrier Strike Group, on station in the Red Sea, & USAF participated in the operation, which hit “dozens & dozens” of targets

~20% of the fleet in theater (thread) Image
Approximately 50% of the deployed U.S. Navy force is in the Indo-Pacific + Med/Middle East area of responsibility.
On Saturday, 15 March, U.S. Central Command executed a series of precision strikes against Iranian-backed Houthi targets across Yemen to “defend American interests, deter enemies, & restore freedom of navigation.”

China has really ratcheted up the bellicose rhetoric recently with warnings, threats, and ultimatums:

• “If war is what the U.S. wants, be it a tariff war, a trade war or any other type of war, we’re ready to fight till the end.”

• “We will come and get you [Taiwan], sooner or later... We make no promise to renounce the use of force.”

• “Rubio’s remarks are steeped in the Cold-War mentality and full of lies and false accusations. The Taiwan question is the most crucial, sensitive and explosive issue in the China-U.S. relations. If the U.S. does not hope to trigger confrontation, they must stop crossing or trampling on the red line.”

• “Anyone who dares to push for ‘Taiwan independence’ will certainly face swift and strong countermeasures from the PLA. And we warn some individuals of the U.S. side: playing sneaky tricks on Taiwan would only backfire.”

• “We warn the [Taiwan] DPP authorities that holding back the tide with a broom will only end up in self-destruction... In the face of the prevailing trend of China’s reunification, any petty tricks by the DPP authorities are futile. Being too cunning by half will end up costing its life. As the PLA has pointed out multiple times, seeking ‘Taiwan independence’ is a dead end. For those who are hopelessly stubborn, let them crash headlong into the harsh reality.”

• “We urge the U.S. to immediately correct its wrongdoings, abide by the one-China principle and three China-U.S. joint communiqués, handle the Taiwan question with extra prudence, stop using Taiwan to contain China, stop upgrading its substantive relations with Taiwan, stop helping Taiwan expand so-called ‘international space,’ stop emboldening and supporting ‘Taiwan independence,’ and avoid further severe damage to China-U.S. relations and peace and stability in the Taiwan Strait.”

Thread: Image
The rapid pace of PLA military activity around Taiwan I covered in my January report continued through February, once again surpassing 2023 and 2024 levels.

Read the January review here, and see below for the February report.
The PLA has deployed in strength across the Indo-Pacific, with a task force currently circumnavigating Australia for the first time and two amphibious surface action groups operating in WESTPAC and the South China Sea.

During February, the PLA held live-fire/shooting exercises in the Western Pacific, South China Sea, Tasman Sea, Gulf of Tonkin/Beibu Gulf, Yellow Sea, and Bohai Sea.
