TRL 6 — Concept Prototype in Testing — Diamondhead, MS

Persistent Sea-Air Combat System

HALIA is the world's first drone engineered to remain on station for weeks with low detectability and launch in seconds — supporting maritime ASW, ISR, and strike missions for U.S. and allied forces.

Threat Environment

Naval Warfare
Is Changing

The United States and its allies face a generational shift in maritime threat. New capabilities, new doctrine, and new technology are not optional — they are existential necessities for maintaining maritime superiority.

Indo-Pacific Competition

China's expanding fleet demands persistent, low-cost maritime surveillance across vast contested waters and critical strategic chokepoints.

Surveillance Gaps

Critical chokepoints lack persistent coverage — leaving allied fleets operationally blind in the zones where submarine threats are highest.

Unsustainable Costs

The P-8A Poseidon costs $200M+ per aircraft. High-tempo persistent ASW patrol is financially untenable at the scale the threat demands.

Drone Proliferation

Adversaries deploy attritable drone swarms and A2/AD systems. Ukraine proves that unmanned systems win. The Navy must keep pace.

Capability Analysis

The Gap That
HALIA Was Born to Fill

Every existing platform forces an impossible trade-off: persist at sea or respond from the air. HALIA is the first system built to dominate both domains simultaneously.

The Solution

Introducing HALIA

The world's first Float-Fly-Float unmanned drone. A persistent sea-air combat system built to operate with low detectability for weeks and respond in seconds in the world's most contested maritime environments.

01
Phase One

Float

HALIA floats low — only ~1 foot above the surface — virtually invisible to radar and visual detection. Motors off. Energy conserved. Persistent ocean presence for weeks without a logistics tail, waiting silently for the moment to act.

HALIA stealth float mode
02
Phase Two

Skate

Patented HoverFoil™ technology blows air through specialized foils to dynamically change buoyancy, raising the platform and accelerating across the water's surface — building launch speed in seas up to 6-foot swells and 17+ knot winds.

03
Phase Three

Fly

At sufficient speed, HALIA lifts off and climbs to altitude in seconds — transitioning from silent ocean sentinel to airborne asset. Execute ISR, strike, ASW sonar deployment, or relay missions at 100+ mph. Return to water. Repeat.

HALIA liftoff

Stealth Floating

Only ~1 foot of body above water when floating. Extremely difficult to detect by radar or visually, enabling covert persistent presence in contested zones.

Patented HoverFoil™

US Patent 12,221,210 B2. Variable buoyancy enabling sea-to-air transition in seconds. Defensible IP moat in the US and Europe with multi-year competitive advantage.

High Sea State Ops

Takeoff and land in 6-foot seas and 17+ knot winds — conditions that ground every other maritime drone platform currently in operation or development.

Mission Agnostic

18 lb payload capacity configurable for ISR sensors, comms relay, ASW sonobuoys, sonar arrays, strike payloads, or custom mission packages for any operation.

Attritable by Design

At a fraction of the cost of a P-8A Poseidon ($200M+) or a manned helicopter, HALIA can be deployed into high-threat zones where risking a $200M aircraft — or a human crew — is not an option.

Force Multiplier

Acts as a communications hub and sensor relay, dramatically amplifying the effectiveness of surface ships, submarines, and aerial drone networks already in the fleet.

Live Demonstration

in Action

This footage shows a planned short-hop test: HALIA skating across the surface, getting airborne, and landing before the waterway ended — exactly as intended. Not a long-range demonstration, just a controlled validation of the Float–Skate–Fly sequence using a real prototype in real water.

Anti-Submarine Warfare Mission Profile

Hunt Submarines.
From Sea Level.

One of HALIA's most critical missions: patrol vast ocean corridors at speed, descend to the water's surface, deploy passive and active sonar arrays to listen for submarines, then re-launch to track and relay contacts in real time — all at a fraction of the cost of a P-8A sortie.

Mission Cost vs. P-8A Poseidon
<0.1%

A single P-8A Poseidon costs $200M+ and $60K+ per flight hour. HALIA performs the same persistent ASW patrol at a fraction of the cost, with zero aircrew risk in contested areas.

On-Station Time
30+ Days

Floating silently in the acoustic convergence zone, HALIA can maintain continuous passive sonar coverage for weeks — listening for submarine transits around the clock without resupply.

Operational Envelope
Sea State 4

Capable of operations in 6-foot seas and 17+ knot winds. HALIA launches and recovers in conditions that would ground conventional seaplane drones and prevent small boat recovery operations.

Mine Countermeasures Mission Profile

Clear the Path.
Without Risking the Fleet.

Floating and repositionable mines are among the most dangerous and hardest-to-counter threats in modern maritime warfare — drifting silently with currents, nearly impossible to map from a distance. HALIA systematically sweeps ocean zones with mine-detection payloads, locates threats, and either reports their position to the fleet or neutralizes them directly — with zero crew in the minefield and no support vessel required.

Multiple HALIAs launched simultaneously to blanket a wide threat area. No support vessel required in the zone.

Zone Cleared

Zero Crew Risk
US Mine Countermeasure Capability Gap
Critical

The US Navy's mine countermeasures (MCM) fleet is aging and limited. Floating and repositionable mines are the hardest to counter — HALIA fills a gap no current platform can address at scale.

Swarm Multiplier
N × Coverage

Deploy a swarm of HALIAs simultaneously to multiply coverage without multiplying cost or crew. Each unit operates independently, requiring no support vessel present in the threat zone.

Asset Risk Eliminated
$0 Crew Risk

Traditional minesweepers cost $50M+, require weeks to deploy, and put sailors directly in mined waters. HALIA removes every expensive asset and every human from the minefield entirely.

Competitive Landscape

HALIA Stands Alone

No other platform combines weeks of sea persistence with high-speed flight and seconds-to-launch capability. HALIA is the only drone optimized for sea persistence — protected by patent.
