Capabilities

Every discipline an XLUUV programme needs.

The vehicle running low over a seabed canyon floor, its light picking out the sand ahead.
01

Hydrodynamic design

Hull forms and control surfaces, evaluated through CFD and physical testing.

The ducted propeller turning at close range, the wake breaking into bubbles behind it.
02

Propulsion

Propellers, evaluated through CFD and physical testing.

The vehicle in a steep descent alongside a rock face, bubbles trailing from its stern.
03

Structural and pressure-tolerant systems

Hull and enclosure design built for sustained depth and pressure.

The vehicle following a plotted route through a narrow canyon, waypoints marked ahead of it.
04

Navigation and autonomy

Inertial and acoustic navigation, and mission autonomy, built for operation without surface positioning.

The vehicle sweeping a sonar fan across the seabed, the returns drawn as concentric rings.
05

Sensing

Sonar, acoustic and multi-sensor fusion, delivering environmental awareness in real time.

The vehicle against a plotted mission, its route drawn over a wireframe model of the seabed.
06

Mission software

Embedded software, payload integration and mission planning, built in-house.

How we build

One development cycle, every programme.

Built to compress the distance between concept and fielded hardware, without skipping a step that matters.

  1. 01

    Design

    Requirements and naval architecture settled before fabrication begins.

  2. 02

    Simulate

    CFD, structural and hydrodynamic simulation, compressing physical prototyping.

  3. 03

    Prototype

    Hardware built early, to learn from rather than to demonstrate.

  4. 04

    Validate

    Every subsystem proven in controlled conditions before it reaches open water.

  5. 05

    Manufacture

    Marine-grade fabrication and assembly inside defence manufacturing infrastructure.
