We Are At Risk of Forgetting the Lessons of the 2017 Collisions
CIMSEC – A common saying in safety organizations is to consider the “half-life of scared” as a measure of the decay of institutional urgency after an accident. In 2017 the U.S. Navy lost 17 sailors in two tragic collisions that prompted an assessment of how the Navy looked at fatigue, human-centered system design, and an overzealous “can-do” attitude. The United States Fleet Forces Comprehensive Review (CR) recommended 112 corrective actions. In the ensuing two to three years, the Navy checked off all those actions as complete and built a system to ensure that the changes were enduring – as recommended by the report. Recent events, however, specifically a series of Class “A” mishaps in the past year, call into question the effectiveness of those changes across the Navy enterprise.
Change the Navy’s Narrative: The Future Fight and the Hybrid Fleet
CIMSEC – With Admiral Caudle assuming the post of Chief of Naval Operations, the Navy has a timely opportunity to realign its strategic narrative with its emerging operational reality, especially in the Indo-Pacific. After years of experimentation with distributed maritime operations, integration of unmanned systems, and renewed industrial partnerships, the Navy must overcome headlines about past scandals and failures to restore the faith of the President, the Department of Defense, Congress, and the American people. The task before the new CNO is to seize this moment and make clear how the Navy will prevail in the next maritime era.

Accelerate Human-Machine Teaming in the Maritime Operations Center
CIMSEC – To maintain maritime superiority in this era of trans-regional, multi-domain warfare, the Navy must accelerate human-machine teaming within Maritime Operations Centers (MOCs). Our adversaries, including our pacing challenge, China, invest heavily in adopting AI technology, a consequential technology for command and control. MOCs serve as the decision hubs of numbered fleets, responsible for executing campaigns at sea and managing maritime task forces. As our Navy fights from the seabed to space and through the electromagnetic spectrum, the volume of data demands our watchstanders employ data-enhancing tools that augment, not replace, human judgment.
China Moves Two Super-Sized ‘XXL’ Uncrewed Submarines To South China Sea

Sink the Kill Chain: A Navy Space Guide to Protecting Ships and Sailors
CIMSEC – Admiral Caudle’s first message to the fleet outlined three priorities: the Foundry; the Fleet and the way we Fight. These priorities cannot be realized without acknowledging the simple fact that the next war at sea will be decided first in space. Ships and Sailors operating inside lethal weapons engagement zones (WEZs) cannot survive against China’s massed, over-the-horizon precision fires unless the Navy treats space operations and Counter-C5ISRT (C-C5ISRT) as foundational, not auxiliary, to naval warfare.

Fort Drum Shows How States Can Push Back on China’s Maritime Aggression
War on the Rocks – The South China Sea is one of the most contested maritime areas in the world. Smaller countries like the Philippines, Vietnam, Malaysia, and Indonesia face increasing pressure from an assertive and militarily powerful People’s Republic of China due to overlapping sovereignty claims and critical trade routes. Beijing’s maritime power projection threatens regional sovereignty and economic rights under the U.N. Convention on the Law of the Sea through its militarization of artificial islands, aggressive maritime activities, and widespread illegal fishing. To address this imbalance, claimant states should adopt asymmetric strategies that improve maritime domain awareness, defend exclusive economic zones, and impose costs on unlawful actions. One such approach is the development of maritime outposts, inspired by the Philippines’ Fort Drum in Manila Bay.

Safety of Navigation is Not the Priority
Center for Maritime Strategy – Safety of navigation is not the priority. It’s the minimum. The surface warfare community’s narrow approach to navigation and seamanship training rewards risk-avoidance instead of risk-mitigation and prevents naval officers from mastering the skills needed for their primary duty—waging war at sea.
