New Details Of Russia’s Super-Weapon Submarine ‘Khabarovsk’

Covert Shores – Russia is investing heavily in a new generation of “super weapons” designed to bypass and potentially nullify conventional defenses. Foremost among them is Poseidon, an autonomous, nuclear-powered, nuclear-armed underwater weapon with effectively intercontinental range. Details about its newest dedicated carrier submarine, Khabarovsk, are only gradually coming into focus.

A Four Ocean Navy: A Wrong Solution to the Right Problem

CIMSEC – Professor Reveron has identified a genuine strategic problem and proposed a historically grounded solution. His geographic differentiation is the correct starting point for the analysis the nation needs. The problem is that he skips that analysis and proceeds directly to organizational and industrial solutions — giving us the Four-Ocean Navy Act before the strategy that would justify it.

Practice Makes Deterrence: India’s Next Nuclear Challenge at Sea

War on the Rocks – India’s ballistic missile-carrying, nuclear-powered submarine fleet is a commendable achievement, but to fully reap the benefits of these powerful platforms, greater operational readiness and doctrinal innovation will be necessary. Some issues will be addressed as India develops more capable boomers with greater endurance and the ability to carry more advanced missiles, while also testing and integrating longer-range missiles.

Lyme Bay MCM Uncrewed Systems Fit Illustrates ‘Hybrid Navy’ Flexibility

Naval News – The UK’s outfitting of its Bay-class auxiliary vessel RFA Lyme Bay as a naval mine warfare (NMW) ‘mothership’ carrying uncrewed systems for the mine-hunting role illustrates how the Royal Navy’s (RN’s) ‘hybrid navy’ approach can provide flexibility to respond to events like the current Middle East crisis, the UK’s navy chief told a conference in London.

Another warship quietly withdrawn – Royal Navy now down to just 5 frigates

Navy Lookout – HMS Iron Duke has been stripped of her weapons and sensors and has not been to sea since October 2025, despite no formal decommissioning announcement being made. Her withdrawal from active service, less than three years after a £103M refit, raises uncomfortable questions about the Royal Navy’s ability to sustain even its much-reduced surface fleet.

Uncrewed Narco-Drone Boat (USV) Found Off Gibraltar

Covert Shores – A small narco-surface drone (USV – uncrewed surface vessel) has been found by Spanish authorities floating off Gibraltar. The black-pained device could easily be mistaken for a submersible. Like the low-profile narco USV recently found in Colombia it appears to use Starlink for communications and navigation. A camera on the nose would allow the pilot to steer it.

Royal Navy team warns of humanitarian crisis as mariners trapped by dual blockade in the Gulf

Navy Lookout – The Strait of Hormuz has effectively ceased to function as an international shipping lane, with the Royal Navy-led monitoring team reporting fewer than 10 vessels transiting daily against a pre-conflict figure of around 130. The International Energy Agency has described the consequences as the greatest global energy security challenge in history and the largest oil supply disruption ever recorded.

US Reveals New Details Of Their Ukrainian Magura USV

Covert Shores – The U.S. Department of Defence (DoD) has released photos on the official media site DVIDS showing a Ukrainian Magura USV (uncrewed surface vessel) at the Balikatan 2026 exercise in the Philippines in April. The exact model may be the Magura V6 or V7. The photos include the loading of a novel shaped charge warhead which was used in the MARSTRIKE-N live firing component of the exercise.

GUGI: Russia’s secretive and strategically important special forces of the sea explained

Forces News – When you hear about Russian subs and warships in UK waters, spying on data cables or testing UK defences, they are probably part of GUGI – the Russian acronym for the Main Directorate of Deep Sea Research. Since the end of the Cold War, GUGI has avoided the defence cuts imposed elsewhere, allowing them to pour millions into submarine development. They are effectively Russia’s Special Forces of the sea, who are capable of carrying out extreme deep sea operations.

China Maritime Studies Institute – Given the substantial increase in sustainment requirements for the PLA Navy’s next-generation aircraft carriers, and acknowledging the limitations inherent in the Type 901 replenishment ship due to the technological constraints of its design era, the next-generation (新型) carrier replenishment vessel is expected to undergo significant modifications compared to its predecessor in several key areas.
