The Navy commissioned the submarine USS Massachusetts in a traditional ceremony held March 28 at Boston Harbor. 

The ceremony culminated a yearslong process to bring the Massachusetts into service. It is the fifth Navy vessel named after the commonwealth of Massachusetts, following the most recent, USS Massachusetts, a battleship that participated in nearly every major Pacific campaign from 1943 to 1945 and earned 11 battle stars for its World War II service.  

Navy Cmdr. Michael Siedsma, the Massachusetts’ commanding officer, spoke proudly of his crew’s efforts.   

“To the crew, the plank owners, the ‘Iron Patriots’ of the USS Massachusetts, we did it,” he said. “Your hard work and unshakable dedication [are] evident. I am amazed and humbled by what we have accomplished.” 

Sheryl Sandberg, the ship’s sponsor, gave the traditional order to “man our ship and bring her to life.” The crew responded, “Aye, aye, ma’am,” before ceremonially running aboard the submarine. 

Sandberg spoke about the Navy’s enduring legacy. 

“In three months, our nation will celebrate the 250th anniversary of the signing of the Declaration of Independence. But as many of you here know, the Navy already celebrated this milestone last October. What does that tell us? It tells us: We don’t have a Navy because we have a country; we have a country because we had a Navy!”  

Following the hoisting of the colors and commissioning pennant, Navy Adm. William Houston, director of the Naval Nuclear Propulsion Program, highlighted the crew’s hard work and the unit’s role in national defense.   

“[The] Massachusetts is playing an incredible role in our security,” he said. “Your crew represents the best that our Navy and our nation [have to offer]. You train relentlessly to bring this warship to life and earned the trust placed on you.” 

The Massachusetts is the 12th Virginia-class submarine and was christened at the Newport News Shipbuilding yard in Newport News, Virginia, May 6, 2023.  

As it joins the fleet, the Massachusetts brings significant warfighting capability, underscoring the nation’s asymmetrical advantage at sea. Virginia-class submarines have enhanced stealth, sophisticated surveillance capabilities and special warfare enhancements that enable them to meet the Navy’s multimission requirements.  

Each Virginia-class submarine is 7,800 tons, 377 feet in length and has a beam of 34 feet. It is designed with a reactor plant that does not require refueling during the planned life of the ship, reducing life-cycle costs while increasing underway time.

Resilient Uncrewed Logistics in GPS-Denied Maritime Environments 

PITTSBURGH, Pa. – March 27, 2026 / The Naval Air Systems Command has awarded Near Earth Autonomy (Near Earth) a contract to develop an aircraft-agnostic autonomy solution for ship-to-shore and shore-to-ship operations through an Other Transaction Agreement (OTA) under the Naval Aviation Systems Consortium (NASC). The work will advance the U.S. Marine Corps’ capabilities for uncrewed logistics missions in contested maritime environments. 

Most uncrewed aircraft systems (UAS) operations rely on infrastructure, including GPS and continuous data.  When these are unavailable or denied, it becomes more difficult, or outright impossible, to complete missions.  Near Earth directly addresses these challenges by enabling UAS to conduct complex maritime logistics, in shore-to-ship, ship-to-ship, and ship-to-shore transfers, without reliance on external infrastructure.  This capability significantly increases operational resilience for naval forces. 

Near Earth’s Firefly compact autonomy system is designed for integration with a wide variety of aircraft. Weighing just 2 pounds, Firefly is light enough to be incorporated into a broad range of Class 3 and Class 4 aircraft, greatly expanding its applicability across the uncrewed aviation ecosystem. It has been successfully integrated on platforms including BAE, L3 Harris, and Pterodynamics. Multiple capabilities will be matured under the contract, including autonomous confined area operations, ship recovery in emissions-controlled (EMCON) environments, and GPS-free navigation. 

This contract with the Navy is a key next step, maturing our autonomous systems performance for maritime missions,” said Sanjiv Singh, CEO of Near Earth Autonomy. “We will build upon our past work on compact systems for uncrewed aerial logistics. This effort supports the Navy’s ability to perform resilient, reliable maritime operations across aircraft.” 

This development will build on Near Earth’s 13+ years of innovation for defense programs. The progression began with Autonomous Aerial Cargo/Utility System (AACUS), which pioneered rotorcraft autonomy for Marine Corps resupply. Building on this, Near Earth miniaturized the Joint Capability Technology Demonstration (JCTD) system for Unmanned Logistics Systems Air (ULS-A), proving autonomy for small UAS in confined areas.  NAVAIR selected Near Earth Autonomy for the USMC Aerial Logistics Connector Program to demonstrate optimized logistics using rotorcraft. The Firefly system represents the latest advancement, enabling small cargo UAS operations for programs like the Marine Corps’ Tactical Resupply Unmanned Aircraft System (TRUAS).   

This contract will be validated through a series of test events to validate requirements, refine operational procedures, and systematically verify system performance. These tests will culminate in a final demonstration with the Naval Air Systems Command at Patuxent River in September 2026, showcasing a full range of capabilities, including ship searching, deck tracking, night operations, and autonomous flights between moving vessels.  

From U.S. Coast Guard Forces Micronesia, March 26, 2026 

SAIPAN, CNMI — Federal and local maritime law enforcement agencies patrolled Saipan’s waters and port together in mid-March, boarding six small vessels and launching new coordination channels that expand the CNMI’s ability to monitor and respond to threats in its surrounding waters. 

From March 18-22, the U.S. Coast Guard Sector Boarding Team conducted joint underway and shoreside operations alongside the CNMI Department of Public Safety Saipan Marine Unit and CNMI Customs and Biosecurity. Teams engaged 12 vessel contacts and completed six small vessel security boardings, while a joint patrol of the Port of Saipan marked the first combined shoreside operation between the U.S. Coast Guard and Customs and Biosecurity. 

The operation also brought together key agency leaders for the first time. SBT members met with an ICE Homeland Security Investigations representative, the assistant director of the CNMI Department of Fish and Wildlife, and the newly appointed chief of the DPS’s Saipan Marine Unit — reinforcing direct lines of communication and cooperation that strengthen maritime domain awareness across the CNMI’s waters and surrounding exclusive economic zone. 

“The Marianas sit at the center of Western Pacific maritime activity: commercial traffic, fishing, small vessels moving between islands,” said Lt. j.g. Thomas Forames-Su, supervisor of the SBT. “These operations are about more than boardings. We’re strengthening the relationships and shared awareness that let us and our partners act faster and more cohesively.” 

Maritime domain awareness is a shared responsibility across federal, local, and community stakeholders. The CNMI’s economy depends heavily on the free flow of maritime commerce, fishing, and tourism, all of which require safe and well-monitored waters. Joint operations, like this one, strengthen the network of agencies and protect those interests every day. 

Building on the momentum from this week’s operations, the U.S. Coast Guard and CNMI partners are planning additional joint patrols, dockside security boardings, and coordinated cutter operations, like the USCGC Frederick Hatch’s recent patrol, in the waters around Saipan and to the north. Agencies are also working to deepen communication protocols and formalize interagency coordination agreements to expand joint response capabilities across the region.
