Under Secretary Emil Michael (@USWREMichael) on the @DeptofWar's announcement of the @USNavy's first advanced nuclear Micro Modular Reactor installation at Naval Weapons Station Crane, Indiana: “We are, thankfully, going through a renaissance in nuclear technology... Military bases need power that’s uninterrupted, not connected to the grid... You’re talking about, hopefully, an explosion in the abundance of energy.”

Today at Ingalls Shipbuilding, I saw our dedicated @USNavy Sailors and Gulf Coast shipyard workers integrating advanced automation and AI. @HII will deliver LPD 30, LHA 8, DDG 129, SSN 800, and CVN 79 by next year. They are building the Golden Fleet and will deliver the agile and lethal force our Nation needs to maintain America's unmatched maritime dominance.

📰 #USNAVY# UPDATE: The Department of the Navy is taking a decisive step to sharpen its competitive edge, reclassifying nineteen planned Virginia Class submarines equipped with the Virginia Payload Module (VPM) as guided missile submarines (SSGN). This pivotal shift clearly differentiates these advanced platforms from traditional Virginia Class fast attack submarines (SSNs), signaling a leap forward in undersea warfighting capability, lethal combat power, and global deterrence.

U.S. Marines with Littoral Combat Force-24 and U.S. Sailors with USS San Antonio (LPD 17) approach USS Gridley (DDG 101) during a Maritime Interdiction Operation Full Mission Profile while underway in the Pacific Ocean, Aug. 21, 2026. U.S. military forces are deployed to the #SOUTHCOM# area of responsibility in support of Joint Task Force Western Hemisphere, @DeptofWar-directed operations, and the President’s priorities to disrupt illicit drug trafficking, deter malign actors and protect the homeland through continuous presence. #JTFWHEM# @The24MEU @USMC @MARFORSOUTH @SecWar @USNavy @NAVSOUS4THFLT

"Today's interdiction and sinking of a floating refueling station used for at-sea drug trafficking operations dealt a direct blow to the logistics network fueling narco-terrorists and cartels in the Western Hemisphere. By severing this critical maritime node, our Joint Force — spearheaded by the precision and professionalism of our Marines and Sailors of Joint Task Force Western Hemisphere aboard USS San Antonio — fractured a primary artery of this illicit logistics chain and sent an unmistakable message to narco-terrorists across the region." - #SOUTHCOM# Commander Gen. Francis L. Donovan #A3C# #JTFWHEM# @DeptofWar @SecWar @USMC @USNavy @USEmbassyEc @DefensaEc @The24MEU

Submarines are getting quieter, smarter, and harder to detect. The US Navy just budgeted $152 million to build a weapon that can reach them from further away — before they get close enough to matter. #AntiSubmarine# #USNavy# #UnderwaterWarfare#

On Sept. 2, at the direction of #SOUTHCOM# Commander Gen. Francis L. Donovan, and in coordination and collaboration with the Government of Ecuador, Joint Task Force Western Hemisphere (JTF-WHEM) successfully interdicted a vessel operating as a floating refueling station in support of illicit at-sea drug trafficking operations in international waters of the Eastern Pacific. Intelligence confirmed the vessel was operating in support of the Los Choneros violent narco-terrorist organization. U.S. Marines and Sailors, launched from USS San Antonio (LPD 17), interdicted, boarded, searched, and cleared the vessel without incident. Individuals removed from the vessel were safely transferred to Ecuadorian Authorities. Once cleared, U.S. forces sank the vessel. This interdiction cuts off a critical node in the traffickers' logistics chain and advances the goals of the Americas Counter Cartel Coalition (A3C) and JTF-WHEM to dismantle narco-terrorist networks. The @DeptofWar and the A3C remain unwavering in their mission to defeat narco-terrorists in the Western Hemisphere and defend our homeland. "We are taking decisive action to dismantle and destroy sophisticated logistics networks used by narco-terrorists to traffic drugs and spread violence throughout the Western Hemisphere. This operation demonstrated the elite capabilities and precision of Joint Task Force Western Hemisphere, which is on watch in the region to apply total systemic friction on these networks." — SOUTHCOM Commander Gen. Francis L. Donovan #A3C# #JTFWHEM# @SecWar @USMC @USNavy @USEmbassyEc @DefensaEc @The24MEU
