Germany considers helping fund UK nuclear deterrent

Posted on by

Navy Lookout – Reports in the Telegraph that Germany is considering financial and military support for Britain’s nuclear weapons are part of a widening debate over European defence. Berlin could help protect the bases and reinforce the conventional forces around them, but access to the deterrent itself would remain tightly controlled by London and constrained by Washington.

The Human Element of Sea Power: Ports, People and Presence in the South China Sea

Posted on by

CIMSEC – The U.S. Navy does not need to match the People’s Liberation Army Navy’s local presence ship for ship in the South China Sea. Instead, the U.S. Navy needs access that links lawful operations at sea to port visits, exercises, repair arrangements, and partner relationships ashore. The human element of sea power, built on trust, access, and routine cooperation, turns ship presence into influence. The decisive factor in the South China Sea is not ship numbers or capabilities alone, but the human infrastructure of access, repair, and partner trust that allows ships to operate with purpose and endurance.

Posted on by

Navy Lookout – Four Royal Navy warships have been involved in a concentrated three-day operation monitoring Russian naval and sanctioned merchant vessels around the UK.

Strategic Assets: The Intelligence Vulnerabilities of the American Shipbuilding Workforce

Center for Maritime Security – It’s widely established that near-peer adversarial actors have actively and clandestinely targeted the U.S. defense industrial base; notable actions include cyber operations and corporate obfuscation to embed itself within the lower tiers of the U.S. supply chain. This extends to the United States’ MIB, with a 2025 Section 301 Investigation Report by the Office of the United States Trade Representative indicating China’s multi-decadal systemic campaign targeting and marginalizing the U.S.’s maritime, logistics, and shipbuilding sectors to diminish the U.S.’s naval dominance and destabilize its maritime enterprise. Accordingly, the shipbuilding enterprise has evolved into a principal arena intensifying the active U.S.-China competition.

Royal Navy to study extending Type 45 destroyers service life

Posted on by

Navy Lookout – Having previously been committed to an out of service date of 2035-38, the MoD now says it has set aside money to study whether the Type 45 destroyers will need to be extended in service. The Type 83 replacement programme has been abandoned, and the alternative Hybrid Navy vision of Common Combat Vessels (CCV) and uncrewed platforms to replace the capability is far from mature.

Asymmetric Spending: Taiwan’s Opportunities to Defend Against Economic Warfare

Posted on by

CIMSEC – Every strategy is ultimately shaped by geography, and no geography in the Indo-Pacific is more decisive than Taiwan’s location between the Strait and the Pacific. For decades, Taiwan, its partners, and even its adversaries have assumed that the island’s fate will be decided westward, across the Taiwan Strait. But the Strait is no longer a protective moat; it is a narrowing corridor easily sealed by missiles, naval patrols, and even insurance premiums. The waters that once carried Taiwan to prosperity now form the most vulnerable seam in its defenses. Taiwan’s endurance depends on building resilience at home and reorienting its future growth eastward.

CMSI Note 24: Crossing a Hellscape: PLA Views on New U.S. Military Concepts to Defend Taiwan

Posted on by

China Maritime Studies Institute – In August 2023, the United States Pacific Command (PACOM) first used the term “Hellscape” to describe a future Taiwan Strait battlefield. That same month the Pentagon unveiled the Replicator Initiative, which reportedly aims to rapidly field thousands of expendable uncrewed systems. Official People’s Liberation Army (PLA) sources have reacted to the U.S. military’s public remarks about Hellscape in a strident fashion. The People’s Republic of China (PRC) defense ministry spokesman said Americans advocating for the Hellscape concept “should prepare to burn in hell” and called such individuals “extremely psychotic.” Yet contrary to the PLA’s dismissive political rhetoric and claims that the U.S. is a “paper tiger,” many military experts in China take Hellscape and Replicator seriously and respect the core premise of employing large numbers of cheap drones, seeing it as one of the keys to the future of war.
