Leviathan's Mission Brief

BLUF

• Leviathan is a government-first, operator-in-the-loop company building long-endurance AUVs
• Our goal is to solve the ever-prevalent endurance bottleneck for Autonomous Underwater Vehicles
• Our engineering and design processes are built for long-term success

Why Leviathan Exists

The ocean remains one of the most strategically important and least understood domains on Earth. Governments need undersea intelligence to monitor contested regions, protect critical infrastructure, and track vessel movement and mine locations. Yet persistent underwater surveillance remains difficult to achieve.

The issue is that most current systems were not designed around persistent presence as the core requirement. They often require periodic resurfacing, support vessels, short deployment cycles, or operational patterns that limit how long they can remain useful in the field.

Leviathan exists to change that.

We are building autonomous underwater vehicles around a clear thesis: endurance is the unlock for the next generation of undersea intelligence.

The Operational Gap

The demand for maritime intelligence is growing while the cost of obtaining it continues to increase.

For decades, undersea surveillance has relied primarily on a combination of manned submarines, fixed sensor networks, and shorter-endurance autonomous systems. While effective in specific situations, each comes with significant tradeoffs.

Manned submarines are among the most capable surveillance platforms built, but they are expensive to operate, limited in quantity, and cannot be everywhere at once. Fixed sensor networks provide persistent monitoring but only within a constrained geographic area. Autonomous underwater vehicles improve flexibility, but many still face endurance limitations that require periodic resurfacing, support vessels, or shortened deployment timelines.

The result is a persistent gap in maritime awareness, and the government is positioning itself to acquire technology to mitigate it.

Over the past year, acquisition pathways for autonomous undersea vehicles have been streamlined, funding has continued flowing toward programs that improve situational awareness, and new initiatives have emphasized the role of unmanned systems in both SOF and INDOPACOM environments, where long-term operations are key.

These signals point toward a clear requirement: autonomous systems capable of operating for longer durations, gathering meaningful intelligence, and doing so at a cost that scales.

Our Vision

The future of maritime awareness will not be built around a handful of expensive platforms operating in isolation.

It will be built around networks of autonomous systems capable of continuously collecting, processing, and distributing information across the underwater domain.

Our long-term vision is simple: 24/7 vision of all of Earth's oceans.

We envision a future where autonomous underwater systems can remain submerged for years at a time, collaboratively monitoring vast maritime regions.

As endurance increases, entirely new mission profiles become possible and logistics become significantly easier.

Over time, we believe this evolves into an ecosystem of autonomous underwater systems optimized for different roles. Some may specialize in surveillance. Others may perform kinetic mine countermeasures, environmental monitoring, or infrastructure inspection, all under the US banner.

At the center of that ecosystem is information.

Success for Leviathan means providing operators with continuous visibility into the regions that matter most, creating a world where understanding the underwater domain is no longer constrained by endurance.

What We're Building

Leviathan is initially focused on intelligence, surveillance, and reconnaissance (ISR) missions. This focus is intentional and addresses government needs.

The United States wants to strengthen their MCM (mine countermeasures) rapidly, clear across J-Books, the DoD budget, and talk with operators. ISR is the first step to a more robust MCM system.

Our first AUV is being designed around a medium-sized form factor capable of operating at depths of up to 5,000 meters. We have a proprietary sensor suite for ISR.

At the heart of our design is our biofilm-powered energy architecture, where we treat the ocean as a source of energy. Our approach combines a stable power source with a source that peaks in power at set intervals. Be sure to read future newsletters for more depth on our design!

Design Philosophy

A good design philosophy indicates a company's survival in an industry where requirements constantly evolve. At Leviathan, every engineering decision is evaluated against three priorities: extended endurance, distributed operations, and cost effectiveness.

Extended Endurance: Endurance is the foundation of everything we do. Rather than treating endurance as a specification to optimize later, we treat it as a core design requirement that influences every major decision we make.

Distributed Operations: Autonomous fleets are most effective when given distributed tasks. Every subsystem should contribute to a future where underwater systems can coordinate, share information, and operate effectively as part of a larger intelligence network.

Cost Effectiveness: The most capable system in the world is not useful if it cannot be deployed at scale. We believe in designing for manufacturability early, understanding supply chains before they become bottlenecks, and ensuring operational costs remain practical for long-term deployment.

These priorities are reinforced by several principles that we consider non-negotiable.

First, we maintain a government-first mindset. We build around operational requirements so we aren't searching for problems that fit a commercially developed technology.

Therefore, operators remain central to the design process. The people who ultimately use these systems understand the operational realities better than anyone else, and their feedback directly shapes the product.

Third, we embrace open architecture whenever possible. Isolated technology, no matter how novel, has no place in government acquisition, and building for partnerships is key. At the end of the day, the most technically interesting underwater vehicle loses to the most operationally useful one.

Engineering Philosophy

Building an extended-endurance AUV is a collection of interconnected challenges in biology, hydrodynamics, controls, manufacturing, materials science, and power systems.

Traditional development approaches often tackle these challenges sequentially: Design the vehicle, build the prototype, test it, discover issues, redesign, and repeat.

We take a different approach. At Leviathan, development occurs in parallel.

While we evaluate vehicle geometries through headless CFD and FEA workflows, we simultaneously test physical prototypes.

We apply the same approach to manufacturing.

Rather than designing a system and worrying about production later, we engage manufacturers early. Supply chains, sourcing, production constraints, and long-term scalability are considered alongside engineering decisions from the beginning.

This approach is especially important for our biofilm development program.

Biology does not operate on traditional engineering timelines. Instead of treating it as a future integration challenge, we have established an independent development and validation pathway that mirrors drug-discovery pipelines.

Our goal is simple: reduce the time between iteration cycles.

Our Competitive Advantage

At Leviathan, we believe our long-term advantage will emerge from the combination of technical, operational, and strategic differentiation.

Technical Differentiation

Our most important technical focus is endurance. The deeper we progress into biofilm-powered energy systems, long-duration operations, and underwater autonomy, the more difficult these systems become to replicate. We believe solving that challenge creates a meaningful advantage.

Operational Differentiation

Government acquisition rewards systems that can be manufactured, integrated, maintained, and deployed reliably. For that reason, we've been building manufacturing relationships, supplier networks, testing pathways, and integration strategies alongside the technology itself, right from day 0.

Strategic Moat

Perhaps most importantly, we are building from requirements rather than from technology. Many companies take commercial capabilities and try to fit them to government problems. We start with the mission and work backwards.

Excited to keep you in the loop as we keep building.
