From production-ready ship design to autonomous surface vessels, Leidos designs and fields systems to deliver sea control and operate and win in contested environments. Powered by the Leidos Autonomous Vessel Architecture (LAVA) platform and sustained with mission-tested contested logistics, we deliver modular mission packages for C5ISR and counter-C5ISR that create tailored offsets across the fleet.

Platforms, payloads, networks, and intel so naval forces can act and win
Delivering integrated maritime operations at speed and scale
In modern naval warfare, superiority is not defined by individual platforms. It is defined by how well platforms, sensors, autonomy, networks, and crews operate as one system—especially in contested environments.
At Leidos, we integrate surface and subsurface fleets, advanced sensing, autonomous systems, fires, resilient networks, and assured command and control into a mission command framework. Grounded in more than a century of naval architecture and decades of mission systems integration, we design to open standards and resiliency from the start so maritime forces maintain freedom of maneuver, control the maritime environment, and dominate the information battlespace.

Engineered to Operate and Win
Sea Archer™
Sea Archer is a mission-configurable small unmanned surface vessel (SUSV) built for contested surface environments. Powered by LAVA autonomy architecture and modular payloads, Sea Archer delivers persistent ISR integrated into distributed maritime operations — extending fleet reach without extending risk to sailors.
Sea Specter™
Sea Specter is a small unmanned surface vessel (SUSV) that operates where conventional platforms lose effectiveness. Its low acoustic and visual signature makes it a critical asset for ISR, force protection, and presence operations in denied environments — delivering persistent capability with precision and control.
Sea Dagger™
Sea Dagger delivers speed, maneuverability, and mission flexibility in a compact, high performance medium unmanned surface vessel (MUSV) platform for time-sensitive surface operations. Integrated into distributed maritime architectures, it extends the fleet’s reach in fast-evolving threat environments.
Sea Hunter
Sea Hunter has demonstrated months-long, open-ocean autonomous operations across thousands of nautical miles. Powered by LAVA autonomy architecture and integrated into fleet C2 systems, this medium unmanned surface vessel (MUSV) delivers operational-scale unmanned capability across anti-submarine warfare, mine countermeasures, and distributed maritime operations.
Hypersonics
Building systems that can travel at Mach 5 or higher, Leidos is enabling precision strike with affordable magazine depth.
Mission critical autonomy
Helping the U.S. Navy expand its reach, speed, and flexibility
As maritime operations grow more contested, Leidos Director, Unmanned Autonomous, Josh Wallick sees true autonomy as mission-critical. “The challenge is how to project naval power forward with minimum risk to sailors. With unmanned surface vessels like Sea Witch, Sea Archer, Sea Dagger, and Sea Specter, you take the human off the ship and operate over the horizon — sometimes with no connectivity — which is why you need true autonomy.”

Sea Control & Sea Denial United with Precision Strike
From advanced acoustic sensing and undersea autonomy to multi-mission vessels and long-range fires, Leidos delivers integrated systems that protect sea lines, deter escalation, and support decisive maritime action.
Sea Dart™
Sea Dart is a compact, high-performance unmanned undersea vehicle built for flexible mission support across defense and research environments. Its payload-agnostic design and compatibility with U.S. Navy architectures enable scalable, low-cost deployment in both contested and scientific missions.
Sea Castle™
Sea Castle is a distributed undersea mission hub enabling UUV recharge, mission data exchange, and sustained operations in forward environments. By extending autonomous endurance without centralized exposure, Sea Castle transforms episodic presence into persistent coverage.
ADC MK 5
The Acoustic Device Countermeasure MK 5 (ADC MK 5) is the U.S. Navy’s next-generation torpedo countermeasure, replacing legacy systems with a high-performance, intelligent micro-UUV. Designed to counter current and emerging heavyweight torpedo threats, it strengthens submarine defense in contested environments.
LAVS
LAVS is a compact, distributed acoustic sensing solution that enhances undersea awareness across operational and research missions. Unlike traditional hydrophones, it adds three-dimensional directional sensing—improving detection accuracy, reducing ambiguity, and accelerating classification. Each variant is optimized for low self-noise and reliable performance in harsh environments.
U.S. Navy deployment puts Leidos autonomy on display
Four unmanned vessels with Leidos autonomy technology cross the Pacific Ocean for the first time and visit several western Pacific ports.
Mission-Ready Maritime Systems
Leidos enables maritime forces to anticipate, plan, and execute logistics with AI-driven readiness tools, global support, and embedded expertise. Our lifecycle management solutions extend system life, improve performance, and reduce obsolescence — ensuring sustained readiness at sea.
Contested Logistics
Leidos modernizes global defense logistics with AI-enabled solutions that strengthen resilience and keep missions moving in contested environments. Using our secure cloud-based platform, Catena, we accelerate C5ISR procurement, use predictive analytics for inventory insight, and drive supply chain performance.
USW Warfare Product Support
Leidos sustains mission-critical combat systems across Navy surface ships and submarines, ensuring readiness for undersea warfare operations. Our 24/7/365 fleet support and training.integrated logistics, and data-driven maintenance improve system reliability while reducing downtime.
Technical Assistance for Repairables Processing (TARP)
Leidos strengthens maritime readiness by improving reverse supply chain performance for repairable assets across the fleet. Our embedded experts deliver on-site support, training, and tracking tools to accelerate repair turn-in, reduce loss, and ensure fast, accurate retrograde execution from routine operations to contingency response.
Decision dominance in action
