In the second week of January 2026, the Department of War (DoW) finalized the operational framework for the Manta Ray Extra-Large Uncrewed Underwater Vehicle (XLUUV) and set the definitive parameters for Project Convergence Capstone 6 (PCC6). Under the leadership of Secretary of War Pete Hegseth, this dual-pronged strategy marks the official end of the “experimentation era” for autonomous systems. The goal for 2026 is the deployment of Human-Machine Integrated Formations where AI does not merely assist the soldier but actively manages the “kill web”—fusing data from the deep ocean to low-earth orbit. As the U.S. faces escalating tensions in the Arctic and Indo-Pacific, these programs provide the “asymmetric edge” required for the “Peace through Strength” doctrine.

I. Manta Ray: Redefining Undersea Persistence

The Manta Ray program, transitioned from DARPA to the U.S. Navy’s operational control in late 2025, represents a fundamental shift in naval architecture. Named for its biomimetic design, the vehicle is the first of a new class of XLUUVs that function independently of manned host vessels or traditional pier infrastructure.

The Logistics of “Field Assembly”

A primary achievement of the Manta Ray in early 2026 is its modular transportability. Unlike the troubled Orca XLUUV, which faced years of delays due to its massive hull, the Manta Ray is designed for expeditionary deployment.

• Global Rapid Deployment: A Manta Ray unit can be shipped in five standard ISO shipping containers. In a demonstration on January 5, 2026, a unit was shipped to a forward operating base in the Pacific and assembled in under 72 hours by a team of twelve technicians.
• Pier Independence: By bypassing traditional naval yards, the Manta Ray avoids logistical bottlenecks. It can be launched from any commercial dock or even a standard cargo ship, making it a “ghost” asset that is difficult for adversaries to track during the deployment phase.

Energy Harvesting and “Hibernation”

The most revolutionary feature of the 2026 Manta Ray model is its ability to operate for months without refueling.

• The Anchored State: The vehicle is equipped with a sophisticated undersea energy-harvesting system. It can anchor itself to the seafloor and enter a “low-power hibernation” state, leveraging thermal gradients and wave motion to recharge its batteries.
• Persistent Surveillance: While in this state, its passive sonar arrays remain active, creating a silent, unmoving sensor mesh that can detect adversary submarine signatures without emitting any acoustic signal of its own.

2026 Mission Profile: The Arctic and the Pacific

The Navy has designated three primary mission sets for the Manta Ray fleet in the current fiscal year:

1. Arctic Domain Awareness: Deploying along the GIUK Gap to provide early warning for the Golden Dome.
2. Subsea Infrastructure Protection: Monitoring trans-Atlantic data cables for evidence of tampering.
3. Mine Countermeasures (MCM): Utilizing its 10-ton payload capacity to deploy “micro-drones” that can neutralize undersea mines in contested straits.

II. Project Convergence: The Road to Capstone 6

While Manta Ray secures the depths, Project Convergence Capstone 6 (PCC6), scheduled for the summer of 2026, serves as the central nervous system for the entire Department of War. PCC6 is the “cut line” where the military transitions from legacy networking to the Next-Generation Command and Control (NGC2) program.

The NGC2 “Clean Slate”

The Army’s NGC2 initiative is a total departure from traditional command structures. It treats the entire battlefield as a single, integrated “data stack.”

• Decision Dominance: The primary metric for PCC6 is “Decision Advantage.” In recent trials conducted by the 4th Infantry Division (4ID), AI battle planners generated “Courses of Action” (COAs) 90% faster than human staff officers, with a 97% tactical validity rate.
• Zero Trust Security: Given the high risk of cyber interference, PCC6 will be the first exercise to fully implement Zero Trust 2.0, utilizing automated AI agents to continuously scan the network for lateral movement by enemy hackers.

Human-Machine Integrated Formations

Under Secretary Pete Hegseth’s “Unleashing U.S. Military Drone Dominance” mandate, the military is moving away from the “operator” model.

• The “Soldier as Commander” Model: Soldiers at PCC6 act as mission commanders, issuing high-level intent to a swarm of autonomous ground and air vehicles that handle scouting and breaching.
• SkyFoundry Integration: PCC6 will test the integration of drones produced by the SkyFoundry initiative—a mass-production model capable of delivering 10,000 “attritable” drones per month. These drones are intended to be used and discarded, ensuring that U.S. forces always have “mass” on the battlefield.

III. Multi-Domain Synergy: Deep Sea to Deep Space

The ultimate goal of 2026 is the seamless fusion of the Manta Ray and Project Convergence into the Golden Dome architecture.

The Integrated Kill Web

During the upcoming Capstone 6 exercise, the military intends to demonstrate a “closed-loop” kill chain:

1. A Manta Ray drone hibernating in the Pacific detects a hostile surface vessel using passive sonar.
2. The drone releases a “Data Capsule” which floats to the surface and transmits the coordinates to the Tranche 3 Tracking Layer (part of the Golden Dome).
3. The NGC2 AI in an Ohio-based command center processes the data and assigns the “target” to a nearby long-range missile battery.
4. The entire process—from detection to engagement—occurs in under 120 seconds, without a single human having to manually input data between systems.

Multinational Interoperability

PCC6 involves the “Five Eyes” partners along with Japan and France. The challenge of 2026 is ensuring that a French sensor can talk to an American shooter. PCC6 is the final proving ground for the Combined Joint All-Domain Command and Control (CJADC2) standard, which mandates that all allied hardware must be “AI-ready” by the kickoff of the 2026 World Cup.

IV. The SHIELD Industrial Complex

To support this massive influx of autonomous hardware, the Department of War has launched the SHIELD (Scalable Homeland Innovative Enterprise Layered Defense) program.

• Massive Contracting: Over 1,000 firms have been qualified for SHIELD contracts, totaling $151 billion over 10 years. This program is the industrial engine driving the production of everything from Manta Ray components to the interceptors for the Golden Dome.
• Software-First Acquisition: Secretary Hegseth’s new philosophy prioritizes software and payloads over “plastic and metal.” This allows for rapid iteration based on soldier feedback from the PCC6 “touchpoints.”

V. Risks and Ethical Considerations

As autonomous systems take a larger role, the DoW faces significant hurdles:

• The “Leaker” Problem: While the Golden Dome is excellent at tracking high-altitude missiles, small, low-altitude drones (“leakers”) remain difficult to detect in dense urban environments—a primary concern for World Cup security.
• Electronic Warfare (EW) Vulnerability: If the connection between a Manta Ray and the NGC2 satellite link is severed, the system must rely on “Edge Autonomy”—the ability of the drone to make decisions based solely on its onboard programming.
• The “Black Box” Dilemma: Commanders at PCC6 have expressed a need for “Explainable AI.” It is not enough for the computer to recommend an airstrike; it must be able to show the human commander why that specific action was chosen.

VI. Conclusion: The Road to June 11, 2026

The opening match of the World Cup on June 11 will serve as the first live operational stress test for this integrated architecture. If the JTF 401 “pop-up” command center can successfully manage the autonomous mesh over 16 host cities, it will prove that the transition to a “Post-PCC6” force is complete. The Manta Ray, SkyFoundry, and NGC2 are no longer just concepts; they are the pillars of 2026 global security.
