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

During the darkest hours of 2 and 3 January, the U.S. conducted operation “Absolute Resolve,” a discreet, precise mission to apprehend Venezuelan president Nicolas Maduro.

The special operations extraction force, escorted by a U.S. Navy, Marine, and Air Force protection package, arrived in downtown Caracas while maintaining the element of tactical surprise, successfully took Maduro into custody, and exfiltrated safely.

A comprehensive review of everything we know to date:
w/ @SA_Defensa, @LatAmMilMVMTs, @__CJohnston__Image
At 22:46 EST on 2 January 2026,  after  "patiently waiting for the right triggers to be met... the weather broke just enough" and POTUS ordered the U.S. military to move forward with operation “Absolute Resolve.”
“Over the course of the night, aircraft began launching from 20 different bases, on land and sea, across the Western Hemisphere. In total, more than 150 aircraft, bombers, fighters, intel, recon, and rotary wing aircraft were in the air.”

The 150+ aircraft worked in “close coordination, all coming together... to layer effects for a single purpose: to get an interdiction force into downtown Caracas while maintaining the element of tactical surprise.”

As the operation began, the helicopters with the extraction force, which included law enforcement officers, took off and began their flight into Venezuela at 100 feet above the water. “As they approached Venezuelan shores, the U.S. began layering different effects provided by SPACECOM, CYBERCOM, and other members of the interagency to create a pathway.”

Overhead, the extraction forces were protected by aircraft from the U.S. Marines, U.S. Navy, U.S. Air Force, and the Air National Guard. The protection package included F-22s, F-35As, F-35Bs, F/A-18E/Fs, EA-18Gs, E-2Ds, B-1B bombers, and other support aircraft, as well as numerous remotely piloted drones.

As the package approached Caracas, the joint air component “began dismantling and disabling the air defense systems, employing weapons to ensure the safe passage of the helicopters into the target area.”

Delta Force arrived at Maduro’s compound at 01:01 AM EST (02:01 AM local time) on 3 January and descended into the compound. “While apprehending the indicted persons on arrival into the target area, the helicopters came under fire and they replied with overwhelming force in self-defense.”

Maduro and his wife surrendered and were taken into custody by the Department of Justice, assisted by the U.S. military, with no loss of U.S. life. After securing Maduro, the force began to prepare for departure “Helicopters were called in to exfiltrate the extraction force while fighter aircraft and remotely piloted aircraft provided overhead coverage and suppressive fire. There were multiple self-defense engagements. As the force began to withdraw out of Venezuela, the force successfully exfiltrated and returned to their afloat launch bases, and the force was over the water.”

By 03:29 AM EST, the 160 SOAR MH-47G Chinook transporting the VIP touched down on amphibious assault ship USS Iwo Jima (LHD 7) in the Caribbean Sea. LHD 7, with its air combat element (ACE) practicing agile combat employment (ACE) in Puerto Rico, has served as a mobile hub for special operations forces in USSOUTHCOM.

One helo was hit during the engagement, but remained operational, and all aircraft made it home safely. Source: Gen. Dan Caine, Chairman of the Joint Chiefs of Staff.

Over the past 48 hours, China surrounded Taiwan and executed large-scale live-fire military exercises featuring simulated decapitation strikes and the seizure of key ports.

“It is a noose-style blockade. The operational scope is no longer limited to symbolic, isolated shows of force, but has evolved into a coordinated and interconnected blockade network, practicing the tactics to choke off the island’s vital supply lines,” the official PLA press account stated bluntly.

With a potential Day 3 on the horizon, here’s everything you might have missed:Image

>>On the morning of 29 December, PLA Eastern Theater Command launched joint military exercises in and around the Taiwan Strait, dubbed “Justice Mission 2025,” and deployed air and naval forces “to approach Taiwan Island in close proximity from different directions”

The PLA Army, Navy, Air Force, and Rocket Force participated. The stated objectives at the outset included:

- Blockade on key ports and areas
- Seizure of comprehensive superiority
- Joint sea-air combat readiness patrols
- All-dimensional deterrence outside the first island chain (new language)
The PRC designated seven exercise zones in the Taiwan Strait and areas to the north, southwest, southeast, and east of Taiwan. From 09:00 to 11:00, the PLA established an 8th training area to the east of Taiwan (per @MoNDefense).

As of yesterday, Reuters reports that 90+ Chinese ships are operating in the region - down from 100+ earlier this week - surpassing China's "mass naval deployment in December last year" in the "largest maritime show of force to date."

A high-level visual (notes + sources below): Image
“The Chinese ships have massed in waters stretching from the southern part of the Yellow Sea through the East China Sea and down into the contested South China Sea, as well as into the Pacific, according to four security officials in the region.

Their accounts were corroborated by intelligence reports from a country in the region, which detailed the deployment. Reuters reviewed the reports on condition it did not name the country.

As of Thursday morning, there are more than 90 Chinese ships operating in the region, coming down from more than 100 at one point earlier this week, the documents showed.

The operations exceed China's mass naval deployment in December last year that prompted Taiwan to raise its alert level, the sources said.”
The Hainan amphibious task group was last spotted ~500nm north of Palau. Australia is closely tracking the ATG but it’s unclear how far south the group will transit. @SinoTalk unpacks why the PLA might conduct a second circumnavigation op and what it would look like:

Mapping potential military targets in Venezuela

Yesterday, the U.S. announced Operation Southern Spear to "remove narco-terrorists from our hemisphere." With the Ford carrier strike group now on station in SOUTHCOM, the U.S. could launch land strikes at any time.

w/ @SA_Defensa Image
"Defense Secretary Pete Hegseth and Joint Chiefs Chairman Gen. Dan Caine returned to the White House on Friday for a second consecutive day of deliberations centered on potential military action in Venezuela, as U.S. forces in the region prepared for possible attack orders.

It remains unclear if President Donald Trump has decided to pursue such an escalation, though high-level discussions over whether to strike Venezuela — and how — have been underway for days...

An administration official said 'a host of options' have been presented to the president." (WaPo)
Special thanks to @SA_Defensa, he’s one of the best in the business.
