Acting Secretary of the Navy Launches New Academic Year at the U.S. Naval War College

A live streamed video in an auditorium

NEWPORT, R.I. – The Honorable Hung Cao, Acting Secretary of the Navy, delivered keynote remarks as the U.S. Naval War College (NWC) began its 2026-2027 academic year with two ceremonies, Aug. 3-4.

On Tuesday, Aug. 4, NWC held its annual Convocation ceremony, welcoming a total of 477 students to the academic year.

Cao, who addressed the Convocation audience virtually from Washington, D.C., called the war college “the leadership laboratory,” urging the enrolled military officers to embrace their roles as leaders, build relationships and stay loyal to their oath, their fellow service members and their allies.

A man speaking at a podium“We’re coming in at a very particular time, with threats looming around the world, but our Navy and Marine Corps are doing the job and securing the pathways,” said Cao. “The strength of our military is not the equipment we have; it’s our Sailors and Marines. As leaders, our one call is to lead those young sailors and Marines the right way. The Naval War College is the leadership laboratory we need, because the first time you meet one another should not be on the battlefield— it should be in places like this where we’re able to share ideas and get to know each other.”

The total of 477 included 292 new students from all six branches of the U.S. armed forces and U.S. federal government agencies, as well as 81 U.S. students continuing into the fall courses after previous November and March enrollments, and another 104 international students from partner and allied nations.

NWC students work to earn Joint Professional Military Education (JPME) credit and either a diploma or a master’s degree in National Security and Strategic Studies or Defense and Strategic Studies.

“Those who enroll in the U.S. Naval War College can expect a rigorous curriculum that will challenge them and, ultimately, forge them into strategists and warfighters who can be successful in any conflict, any time and any place,” said NWC President Rear Adm. Darryl Walker. “Many of the greatest military leaders our nation has seen in the last century and a half have been students or faculty here at the war college. We know there are many future commanders and flag officers among the students in the audience at convocation every year. It’s a proven fact.”

A group of seated people clappingEach year, nearly 500 in-resident students graduate, with 60 percent being selected for command of ships, squadrons and other military units. In the U.S., the college has also produced three Chairmen of the Joint Chiefs of Staff, 15 Chiefs of Naval Operations and 13 other service branch heads.

Additionally, the college welcomes between 100 and 150 foreign officers to the U.S. from around the world each year to study strategy, warfare, decision making, and operational art. Since creating a program for international officers in 1956, the NWC has more than 5,500 international alumni from 145 countries worldwide. Approximately 10 percent of the alumni from the college’s international programs have gone on to become heads of their country’s respective navy.

The day before Convocation, NWC’s annual Cloister ceremony welcomed more than 300 faculty members from the college’s in-resident and distance education programs to celebrate faculty accomplishments and prepare for the academic year ahead.

During the event, the faculty was formally introduced to the war college’s new provost – the institution’s top academic officer – retired U.S. Navy Capt. Michael O’Hara, Ph.D. O’Hara previously served as the dean of the college’s Center for Naval Warfare Studies (CNWS).

“As a military and civilian faculty team, we teach in rigorous ways to prepare officers to be critical thinkers,” O’Hara told the assembled faculty during Cloister. “We challenge them through readings, case studies, and seminar discussions to take estimates of situations, to express intent, to consider alternate points of view and counterarguments. We immerse them in practical problems to plan and integrate joint all-domain operations from seabed to space. We wargame them and pit them against thinking opponents who sharpen their abilities to think at the operational-level of war and at the strategic-level, too.”

A man speaking at a podiumAlso during Cloister, faculty members were recognized and presented awards for superior achievements in teaching and research related to their specific disciplines.

Among those recognized were Dr. Michael Poznansky, from CNWS’ Strategic and Operational Research Department (SORD) and Cyber and Innovation Policy Institute (CIPI), and U.S. Marine Corps Lt. Col. Marc Blankenbicker from CNWS’ War Gaming Department, who received the Civilian and Military Faculty Awards for Excellence in Research, respectively, for distinguishing themselves by formulating critical questions, investigating key data resources, and synthesizing and sharing innovative ideas.

Dr. Leigh Ann Perry of the College of Leadership and Ethics (CLE) and U.S. Navy Cmdr. Daniel Post of the Strategy & Policy Department received the Civilian and Military Faculty Awards for Excellence in Service, respectively, for providing excellent service to NWC and the greater community.

Prof. William Murray of SORD and the Halsey Bravo Research Group and U.S. Marine Corps Lt. Col. Matthew Rohlfing of the Maritime Advanced Warfighting School (MAWS) received the Civilian and Military Faculty Awards for Excellence in Teaching, respectively for providing a superb academic environment and educational experience for their students.

Retired U.S. Navy Capt. Thomas Mangold, Dr. Michael Martin, Dr. Robert Tomlinson, Dr. Mary Thompson-Jones and Dr. Donald Marrin were awarded status as emeritus professors, honorary titles that are carried into retirement and denote distinguished accomplishment during their careers as faculty.

Established in 1884, NWC informs today’s decision-makers and educates tomorrow’s leaders by providing educational experiences and learning opportunities that develop their ability to hedge aggressively, innovate continuously, fight distributively, delegate confidently, and command with clarity within complex battlespaces.

 

Defense News in Brief: Department of the Navy Establishes Direct Reporting Portfolio Manager for Robotic and Autonomous Systems

Source: United States Navy

WASHINGTON — Acting Secretary of the Navy Hung Cao today announced the establishment of the Direct Reporting Portfolio Manager for Robotic and Autonomous Systems (DRPM RAS), a strategic restructuring to tightly integrate the development, requirements, and acquisition of RAS capabilities across the Department of the Navy (DON).

DRPM RAS leverages the successful and proven DRPM model first established for submarines. This marks a decisive step toward correcting years of fragmented requirements, resourcing, and acquisition practices that dispersed accountability, complicated industry engagement, and slowed delivery to the warfighter. The organization is designed to operate in concert with the Department of War’s DRPM for unmanned offensive and defensive systems (UxS).

Christopher Miller will serve as the acting DRPM RAS, reporting directly to William Toti, performing the duties of the Under Secretary of the Navy. Miller will concurrently serve as acting Portfolio Acquisition Executive RAS, mirroring the DRPM Submarine model.

“We are at an inflection point in naval warfare, and the Department has been approaching robotic and autonomous systems through arcane processes that do not deliver capabilities at the speed our Sailors and Marines need,” said Toti. “Secretary Cao has directed us to replace that model with clear accountability, faster decisions, and a relentless focus on the warfighter.”

The DON is also reviewing the potential relocation of DRPM RAS staff out of Washington, D.C. and closer to Fleet warfighters. The review is assessing whether such a relocation would strengthen collaboration with operational forces and ensure Fleet feedback remains closely connected to capability development and fielding.

“To remain the most lethal and technologically advanced maritime force in the world, we must both improve and accelerate how we partner with industry to develop and deliver the next generation of warfighting capabilities,” said Miller. “Success depends on ensuring operational requirements drive rapid development so we’re delivering the right solutions to the warfighter.”

The establishment of DRPM RAS marks a significant step in the DON’s effort to modernize acquisition governance and strengthen maritime deterrence.

Capt. Thomas Flaherty, commander of Submarine Squadron (SUBRON) 4, under which Virginia operates, welcomed the crew home and praised their efforts.

“The deployment of USS Virginia to the European theater underscores the critical role our undersea forces play in maintaining security and stability alongside our international partners,” Flaherty said.”The crew of Virginia executed highly demanding missions with the utmost professionalism and precision, demonstrating the elite capabilities of our fast-attack fleet. Their performance on this deployment has set a high standard for readiness, and we are incredibly proud to welcome them back to their homeport here in New London.”

Wheelis said he considered it an immense privilege to welcome the crew and their families back to Submarine Base New London after a challenging and rewarding deployment.

“This homecoming is a time to celebrate the sacrifices made by our Sailors and the support of their families and loved ones,” Wheelis said.“To the families: thank you for your patience and strength while your Sailor dedicated six months to defending our freedoms and strengthening national security. To the crew: your steadfast commitment to each other is astonishing. Keeping Virginia in the fight and ready to execute was no easy task, but your grit was unmatched and reflects great credit on this command and what the United States Navy is about.”

During the deployment, the crew successfully kept Virginiaon station through three extensive periods of national tasking in arduous and austere environments.

“My ship and my crew were consistently in the right place at the right time and ready to respond to any threat to our freedoms with overwhelming force,” Wheelis added.“As we reunite, we look forward to a period of well-deserved rest, maintenance, and time with family, while remaining ready to answer the nation’s call whenever needed. Welcome home, Virginia—I’m proud of you and your accomplishments.” While deployed, Virginiasteamed more than 36,000 nautical miles and conducted a key port visit to Tromsø, Norway.

The deployment marked major milestones for the crew: 46 personnel earned their submarine warfare devices—commonly referred to as “dolphins”—and five Sailors welcomed new babies.

Hospital Corpsman 1st Class David Griffenbergand his spouse, Molly Griffenberg were honored with the ceremonial first kiss on the pier. Chief Logistics Specialist (Submarine) Brian Boyd was awarded the ceremonial first hug with hisspouse, Sarahi Boyd.

USS Virginia is the tenth U.S. Navy vessel named for the Commonwealth of Virginia, following the most recent USS Virginia (CGN 38), a Virginia-class cruiser commissioned in 1976 and decommissioned in 1994. Previous ships to bear the name USS Virginia included the first USS Virginia of the Continental Navy, a 28-gun sailing frigate built in 1776, and the Virginia-class battleship (BB 13), commissioned in 1906. The submarine Virginia has a crew of more than 130 personnel, is more than 377 feet long, and can displace nearly 7,900 tons.

The Virginia-class of nuclear-powered fast attack submarines are designed for a broad spectrum of open-ocean and littoral missions. Fast-attack submarines are multi-mission platforms enabling five of the six Navy maritime strategy core capabilities – sea control, power projection, forward presence, maritime security and deterrence. They are designed to excel in anti-submarine warfare, anti-ship warfare, strike warfare, special operations, intelligence, surveillance and reconnaissance, irregular warfare and mine warfare. Fast-attack submarines project power ashore with special operations forces and Tomahawk cruise missiles in the prevention or response to regional crises.

SEACAT 2026 is a multilateral exercise designed to enhance maritime cooperation among the participating nations and to provide mutual support in addressing maritime crises, contingencies, and illicit activities. The exercise’s shore phase in Singapore includes the newly integrated Maritime Operations (MAROPS) Forum, combining previous operations and intelligence workshops to enhance realism and collaboration, where participants will share best practices, refine integrated maritime processes, and prepare for the at-sea phase.

Concurrently, a revised Senior Leader Forum (SLF) engages senior military leaders from participating nations to share lessons learned on collective maritime challenges, improve understanding of integrated maritime operations, and participate in a capstone tabletop exercise alongside operational commanders and Intelligence, Surveillance, and Reconnaissance (ISR) operators.

“This year’s SEACAT marks a significant evolution in how we train and cooperate, highlighting the strength of the enduring partnerships we’ve built and our collective capability to work side-by-side in support of a free and open Indo-Pacific.” said U.S. Navy Capt. Aaron Taylor, commander, Logistics Group Western Pacific/Task Force 73. “By combining our operations and intelligence workshops into the new Maritime Operations Forum and enhancing our Senior Leader Forum, we are building a highly integrated maritime team. This enables us to collectively address modern, complex threats, ranging from unmanned systems attacks to maritime sovereignty incursions, ensuring our partners remain ready to defend regional security, protect critical sea lanes, and uphold international law.”

During the SEACAT sea phase, participating nations will practice tracking and intercepting simulated vessels sailing through Southeast Asian waters. Participating nations will work to provide real-time sensor cueing and vessel contact information to partner Operational Centers (OPCENs), Maritime Patrol Reconnaissance Aircraft (MPRA), and surface assets. By exercising these complex scenarios in real time, which include critical regional challenges such as search and rescue, illegal fishing, contraband smuggling, and maritime sovereignty incursions, SEACAT participants enhance their collective capacity to detect, deter, and counter modern maritime threats in accordance with international law.

SEACAT demonstrates shared commitments to maritime partnership, security, and stability in the Indo-Pacific. The Sixteen nations participating in SEACAT 2026, includes Bangladesh, Brunei, Canada, Fiji, India, Indonesia, Malaysia, the Philippines, Singapore, Sri Lanka, Thailand, Timor Leste, Tonga, UK, Vietnam, and the United States.

U.S. 7th Fleet, the U.S. Navy’s largest forward-deployed numbered fleet, routinely interacts and operates with allies and partners in preserving a free and open Indo-Pacific region.

Defense News in Brief: Not Theoretical but Personal: Naval Leaders Celebrate ONR at Anniversary Event

Source: United States Navy

ARLINGTON, Va.—Looking back on his career as a U.S. Navy diver and explosive ordnance disposal officer, Acting Secretary of the Navy Hung Cao shared a personal perspective on the scientific and technological legacy of the Office of Naval Research (ONR).

“While many of ONR’s discoveries shaped the wider world, other less well-known breakthroughs transformed the daily lives of our Sailors and Marines on the front lines,” he said. “Having served in Iraq, Afghanistan and Somalia, my perspective is that what ONR does isn’t theoretical — it’s personal. It’s what saved our lives over there.

“For eight decades, ONR has stood at the vanguard of naval power,” Cao continued. “You’re the operational engine that transforms science fiction into tactical reality on the high seas.”

Cao gave his remarks during a special celebration honoring ONR’s 80th anniversary. Held on July 31 in the Pentagon Auditorium, the event highlighted eight decades of critical scientific and technological innovation for the U.S. Navy and Marine Corps.

In addition to commemorating historical achievements, the celebration discussed the future of integrated naval power and technological dominance — and featured more than 20 ONR technology displays on the second-floor Apex of the Pentagon’s 9th and 10th corridors.

Chief of Naval Research Dr. Rachel Riley talked about ONR’s newly released 2026 Science and Technology Strategy, which calls for a fundamental transformation of how the command prioritizes, develops and deploys technology to the Navy and Marine Corps.

Riley also introduced the CNR Fellows program. Launching this year, the fellowship brings newly tenured academic professors to ONR for a one-year term to learn about naval priorities, and provide technical oversight and state-of-the-art expertise.

“Every time I come to the Pentagon, I think about a poster here that has a George Washington quote from 1780,” said Riley. “It says, ‘There’s nothing so likely to produce peace as to be well prepared to meet an enemy.’ It speaks to the broader importance of ONR’s mission — to ensure that every U.S. Sailor and Marine, every platform within the Joint Force, is equipped with the latest and greatest technology.”

In addition to Cao, ONR’s anniversary celebration featured other prominent guest speakers:

  • Adm. James Kilby, Vice Chief of Naval Operations
  • Dr. Joseph S. Jewell, Assistant Secretary of War for Science and Technology
  • Dr. Peter W. Singer, noted author, strategist and futurist

“For 80 years, the Office of Naval has shaped the way we fight,” said Kilby. “Long before a ship is commissioned or a capability reaches the fleet, someone had to imagine that was possible. For 80 years, that has been ONR’s mission — to look beyond today’s requirements and prepare for tomorrow’s fight.”

Jewell recalled his time as a university professor and awardee of ONR’s Young Investigator Program — and expressed gratitude for the command’s sustained support of his academic research in hypersonics.

“The innovations taking place through ONR are truly mission-driven, and support the warfighters of today and tomorrow,” he said. “The mission of ONR is paramount to our nation’s economic and national security.”

During his presentation, Singer outlined five technological areas — what he called “lineages” — in which he believes ONR has been particularly effective since its establishment in 1946:

  • Unmanned systems, robotics and autonomy
  • Sensor improvement and integration
  • PNT, C5ISR and battlespace awareness
  • Ocean science, acoustics and undersea warfare
  • Troop protection, materials and human performance

“In 1946, ONR started with six basic branches, including physics, fluid mechanics, aviation and physiology,” said Singer. “From that structure, ONR has taken into areas that now extend from cyber to autonomy to directed energy. Entire departments are named after words that didn’t even exist in 1946. That shows an organization evolving and changing the very lexicon of human scientific and military capability.”

Defense News in Brief: Navy to Reclassify Virginia Payload Module-equipped SSNs to SSGNs, Unleashing Next-Generation Strike Power

Source: United States Navy

“This reclassification is a clear acknowledgment of the increased lethality VPM brings to the undersea fight,” said Vice Adm. Rob Gaucher, Director, Submarine Programs. “These VPM-equipped SSGNs will ensure the Navy continues to dominate the undersea domain for decades to come. By integrating this additional payload capacity, we will have the ability to surge strike power to assure our allies, deter aggression, outmatch any adversary, and give our Fleet commanders an incredibly versatile, hard-hitting instrument of national power.”

This decision highlights the formidable capabilities of the Navy’s newest undersea assets. Encompassing Virginia Class Blocks V and VI, these platforms will deliver with the integrated VPM—a hull modification that significantly increases length, boosts munition capacity, and provides unprecedented payload flexibility. By putting high-volume, long-range precision strike capabilities directly into the hands of the Fleet, these SSGNs will serve as a vital cornerstone for Distributed Maritime Operations and high-end warfighting. While carrying the new SSGN designation, they will remain an integral part of the storied Virginia Class program.

“Reclassifying Virginia Payload Module-equipped submarines as SSGNs accurately reflects the extraordinary strike capacity, operational flexibility, and global reach these platforms bring to the Fleet,” said the Chief of Naval Operations, Adm. Daryl Caudle. “This transition comes at an important moment as USS Georgia, one of the Navy’s four Ohio-class guided-missile submarines, begins the inactivation process after more than four decades of exceptional service. Georgia and her sister ships proved the enduring value of combining undersea stealth with unmatched clandestine strike capability. The next generation of Virginia-class SSGNs builds on that legacy with greater survivability, adaptability, and sustained combat power. These submarines will provide our Nation with a powerful and persistent deterrent, expand options for our combatant commanders, and ensure the Navy remains ready to fight and win whenever and wherever called upon.”

The first VPM platform (SSGN 803) is estimated to deliver in FY 2029, with deliveries scheduled through FY 2038. Once operational, these highly survivable platforms will be dynamically employed across crucial global theaters—providing persistent forward presence, reinforcing robust alliance deterrence, and standing ready to project decisive combat power at a moment’s notice.

“The Submarine Force is defined by our ability to operate undetected and strike without warning,” said Vice Adm. Rick Seif, Commander, Submarine Forces. “By integrating high-volume precision strike capabilities into these stealth platforms, these SSGNs serve as the ultimate enabler for Distributed Maritime Operations, giving our warfighters the overwhelming, flexible firepower required to win decisively in any theater.”

Virginia Class submarines are built to dominate a broad spectrum of open-ocean and littoral missions, including anti-submarine warfare, anti-surface warfare, precision strike, intelligence collection, irregular warfare, and mine warfare. Armed with state-of-the-art sensors, unmatched stealth, and advanced automation, these reclassified SSGNs will operate with impunity in contested waters, ensuring the United States Navy maintains absolute undersea supremacy.

 

Defense News in Brief: 24th Marine Expeditionary Unit and USS San Antonio Transit Panama Canal

Source: United States Navy

PANAMA CANAL — On August 1, 2026, the 24th Marine Expeditionary Unit (MEU) — operating as Littoral Combat Force-24 (LCF-24) — aboard the amphibious transport dock ship USS San Antonio (LPD 17), completed a transit through the Panama Canal while operating under United States Southern Command.

 

 

Marking the first time a Marine Expeditionary Unit has navigated the canal since 2008, this large-scale maneuver is a demonstration of the Marine Corps’ capacity for rapid global mobility, maritime dominance, and seamless power projection.

Since its completion, the Panama Canal has served as a vital strategic pathway for the United States and its allies. The canal allows naval vessels to rapidly shift between the Atlantic and Pacific theaters, saving weeks of travel around South America. Navigating this critical maritime shortcut ensures the U.S. military can maintain a flexible, responsive posture — surging ships and troops to meet emerging crises across hemispheres without delay.

“This historic transit is a powerful testament to the flexibility and readiness of Littoral Combat Force-24,” said Col. Ryan Lynch, the commanding officer of LCF-24. “Our ability to seamlessly navigate this critical waterway alongside our Navy partners aboard the USS San Antonio demonstrates our capability to rapidly project power and respond to crises anywhere in the Southern Command area of responsibility. We are ready to operate straight from the sea, at a moment’s notice.”

The transit serves as a validation of the Littoral Combat Force concept and the modern Marine Air-Ground Task Force. It proves LCF-24’s ability to navigate narrow waterways and project assets ashore without relying on established military basing, underscoring the Marine Corps’ enduring role as the nation’s premier force-in-readiness, perfectly calibrated for contested littoral regions.

The foundation of this capability is the unbreakable teamwork between the Navy and the Marine Corps. The interoperability displayed by the Marines of LCF-24 and the Sailors of the USS San Antonio highlights a fully integrated naval force supporting Combatant Commander objectives.

By moving fluidly through the canal, the Blue-Green team proves its unrestricted access to the U.S. Southern Command area of responsibility, which spans Central and South America, and the Caribbean. Whether tasked with humanitarian disaster relief, bolstering regional partnerships, or deterring aggression, this force can reach anywhere in the region to deliver tailored, decisive effects.

The 24th MEU’s transit of the Panama Canal proves that the Navy-Marine Corps team remains prepared to respond as America’s 9-1-1 force in any clime and place.
