CMSI Note 18: Flooding the Zone: The Use of Civilian Landing Craft (LCTs) in PLA Amphibious Operations
China Maritime Studies Institute – In July and August 2025, China’s People’s Liberation Army (PLA) employed a unique type of civilian deck cargo ship known as a Landing Craft Tank (LCT) to transport military vehicles directly to shore as part of an amphibious landing exercise. While civilian deck cargo ships of this type have been observed in previous PLA over-the-shore logistics exercises, they had only been used to transport vehicles and equipment from port-to-port—simulating the transport of forces into a captured port—not directly to an unimproved beachhead. If the PLA develops the ability to coordinate and employ significant numbers of civilian LCTs to transport forces directly onto Taiwan beaches, it could significantly improve its over the-shore assault capacities and logistics capabilities.

SWO Specialization – Specialize By Platform Groups To Win The High End Fight Part 1
CIMSEC – To win the fight against a peer adversary, the navy’s surface warfare officer (SWO) community must display a level of warfighting proficiency – one of excellence – not yet seen in many years. The collisions of 2017 and continued near misses and actual mishaps since, such as the grounding of USS Howard (DDG 83) in 2023 and the Harry S. Truman (HST) Carrier Strike Group (CSG) friendly fire incident in 2024, reveal that the surface force lacks a high level of operating proficiency, in terms of both shiphandling and tactical skill. However, while sweeping reforms were swiftly implemented to increase shiphandling proficiency, the SWO community has not shown the same kind of fervor to implement the sweeping changes needed to dramatically increase tactical proficiency.
Italy’s DDX Destroyer Tender Path Starts Now
ItaMilRadar – Italy has formally set the procurement machinery in motion for two new-generation destroyers—labelled DDG in official language and widely referred to as DDX. This is not just another shipbuilding line item. By signalling a negotiated procedure run through OCCAR and already framing Orizzonte Sistemi Navali (OSN) as the unavoidable industrial counterpart, the Ministry of Defence is effectively locking in the governance, the industrial architecture, and the strategic intent of Italy’s next “high-end” surface combatants.

The Russian cargo shipwrecked in the Mediterranean a year ago was transporting nuclear reactors for North Korea
Le Parisien – Is the mystery surrounding the sinking of the Ursa Major about to be solved? A little over a year ago, this Russian cargo ship had sunk into international waters, somewhere between Spain and Algeria. On December 23, 2024, the ship was hit by three explosions in the engine room, a “terrorist attack”, according to its owner, the company Oboronloguistika under the Russian Ministry of Defense. Two sailors were then reported missing.
This cargo ship, under US sanctions since 2022, had left St. Petersburg two weeks earlier and was to reach the port of Vladivostok, located in the Russian Far East. At the time, Oboronloguistika had explained that the ship carried mostly empty containers, Liebherr cranes, as well as hatch covers for icebreakers. But according to the investigation by the Spanish authorities, revealed by the media La Verdad, the latter are in fact the envelopes of two VM-4SG nuclear reactors of nearly 65 tons each.

Containing the Threat of Containerized Missiles
War on the Rocks – In any war over Taiwan, American commanders will face a problem that barely existed a decade ago: China can hide lethal military systems inside standard commercial shipping containers. These “containerized” missile launchers are modern renditions of an old U.S. Navy concept first marketed in the Russian Club-K and are now reportedly fielded in Chinese variants. They ride on the decks of merchant ships, blend into global commerce, and give Beijing the ability to forward-deploy precision weapons without visibly deploying a single warship.
China’s Q-Ship Containerized Weapon System
Covert Shores – Putting weapons onto a merchant vessel is nothing new of course, and the concept of containerized missiles in standard ISO 40ft (12m) is very much in vogue. Iran, Israel, Turkey and Russia are among the countries to have already done this, or at least proposed it. Yet it remains novel and the latest Chinese vessel stands out in several important ways.
The Royal Navy’s future Large Uncrewed Surface Vessels and the cultural obstacles to autonomy
Navy Lookout – In this guest article, Matthew Bell, an officer in the Royal Australian Navy, considers the cultural challenges may be a bigger barrier to the RN’s adoption of Large Uncrewed Surface Vessels (LUSVs) than technical issues such as satellite bandwidth or artificial intelligence. Bringing LUSVs into service will mean changing long-standing maritime traditions, not just updating technology.
