Chinese Buoys Near the South Korea-China PMZ

Asia Martime Transparency Initiative – China’s deployments of buoys in the Yellow Sea add yet another layer to its approach toward managing disputes with South Korea while furthering its own maritime interests. Like many of China’s maritime activities, the buoys accomplish several things simultaneously: they increase China’s monitoring and sensing capabilities in an important maritime area; they assert control over a less sensitive but still disputed portion of overlapping maritime claims; and, importantly in the Yellow Sea context, they test South Korean reactions to inform future deployments. 

Navy’s Top Admiral Wants To Tailor Warship Deployments To Specific Missions

The War Zone – While today’s surface Navy puts major emphasis on carrier strike group and expeditionary strike group deployments, driven by the resource realities and the global threat environment, the current Chief of Naval Operations (CNO) wants to take a far more flexible and tailored approach to sending his vessels on cruise.

The Trump-Class Batttleship: Spectacle Wins Out Over Combat Power

FRPI – Plans have now been unveiled for the USS Defiant, the lead ship of the so-called Trump class of guided-missile battleships. According to the concept materials released so far, this vessel would combine a sprawling arsenal of vertical launch cells, hypersonic missiles, and lasers with a forward-mounted 32-megajoule railgun. In other words, at a moment when American shipyards are struggling to produce sufficient numbers of current surface combatants, the proposed solution is to task them with building 35,000-ton “super combatants” packed with immature or outright nonexistent technologies.

Could such a ship actually work? What risks does it introduce, technologically and industrially? And perhaps most importantly, what would a return to battleships mean for American fleet structure and an already overstretched US shipbuilding sector?

From Constellation to Cutter – the US Navy’s gamble on delivery over capability

Navy Lookout – The US Navy says it wants to terminate the Constellation-class frigate programme after years of design instability, opting instead for the procurement of a simpler ship based on the US Coast Guard’s Legend-class cutter. Here, we consider the crisis in American naval procurement and the implications of the switch from frigate to cutter.
