A Newsweek map shows where the United States has maintained a presence of nuclear-powered submarines across three island chains in the Pacific through deployments and port calls, as part of Washington's efforts to contain China's growing naval power. www.newsweek.com/map-us-nucle...

The Greek government tonight moved forward with the decision to procure a fourth FDI frigate for the Hellenic Navy. The Hellenic Parliament now has to vote to approve this decision. This formality is expected to take place next week 🇬🇷 www.navalnews.com/naval-news/2...

India’s shift to Western partnerships for submarine projects shows, among many things, that Russia’s diesel electric submarine designs are no longer competitive

Upgrades for Taiwan's ROCS Hai Lung attack submarine are complete. She is one of two modern submarines in Taiwan. She is expected to participate in anti-submarine exercises off southwestern Taiwan later this month, along with maritime patrol aircraft and ASW helicopters.

A few years ago @wellerstein.bsky.social got a hold of the Fatman Mark III maintenance manual. Think maybe from John Coster-Mullen if memory serves me correctly. The photo quality was poor so I have been piecing together original photos to match images in manual. Here’s a thread with a few examples.

A U.S. Navy RFI has outlined the future of subsurface naval combat capability within the AN/BYG-1 combat system, the U.S. Navy’s undersea warfare combat system used on all American submarines, as well as submarines operated by the Royal Australian Navy www.navalnews.com/naval-news/2...

It’s too early to say which surface drone (USV) was used in the sinking of the Ukrainian intelligence ship Simferopol on the Danube River, but it shows the maturing of Ru capabilities. It was a well planned and executed attack. Very sobering. Relevant Russian USVs www.hisutton.com/Russian-USVs...

Sweden's first autonomous UUV will be launched next summer. It is a prototype of a new class. It is expected the class will be armed with mines or torpedoes. @corporalfrisk.com @covertshores.bsky.social @nerdicdefence.bsky.social @saturnax1.bsky.social if you haven't seen this already.
