Autonomous Undersea Vehicle Completes 100-Hour Demonstration

nduril Industries is trying to define the next
frontier of autonomous maritime operations.
Just as the Dive-LD set a new global standard for
Large-Diameter Autonomous Undersea Vehicles
(LD-AUV), the Dive-XL, Anduril's commercial
Extra-Large Autonomous Undersea Vehicle
(XL-AUV), is setting a new global standard for
what is possible for vehicles of this size.
Dive-XLs are at-sea nearly every single day in Australia
and the United States, and the vehicle recently
concluded a 100 hour single voyage - the longest
underway for a vehicle of this class. This,
however, is just a waypoint, which will eventually
be superseded, as the company moves toward a far
more ambitious goal: a 1,000 nautical mile, fully
submerged mission that the Dive-XL will conduct
in the first half of 2025. That achievement will itself
be just another important milestone as the company
seeks to unlock the full, multi-thousand mile
range of the vehicle.
Unlike hybrid uncrewed submarines, which
require frequent contact with the surface, Dive-XL is
designed to operate undersea for the entirety of its missions.
This is not just a technical achievement - it is a mission-critical
capability. The longer an XL-AUV can stay submerged,
the more operational flexibility it provides its commanders.
Dive-XL's producibility stems from a fundamentally different
approach to design and manufacturing. It's modular
design is freely flooded, relying on smaller, commercial off
the shelf pressure vessels to house critical systems like navigation,
communications, and batteries. The core vehicle is
constructed from affordable and commercially available
marine grade materials such as aluminum and fiberglass.
This architecture reduces complexity, lowers costs, and
makes Dive-XL highly manufacturable with resilient supply
chains across the globe. Production doesn't require bespoke
materials and specialized shipyard labor, but can instead tap
into the commercial automotive workforce, minimizing
retraining time and expanding the industrial base.
Across two completely different maritime environments
on opposite sides of the Pacific Ocean, Dive-XL vehicles are
in and under the water right now, undergoing daily testing
to validate their endurance, reliability, and versatility. Following
the completion of the Ghost Shark R&D program last
year, the platform is slated to enter production, with the
stated intent of the Australian Government to have first production
vehicles in the water by the end of 2025. These production
variants will feature substantial improvements in
range, speed, navigation and affordability, all while being
easier to manufacture at scale.

I
n December, the Federal Aviation Administration (FAA)
and the European Union Aviation Safety Agency (EASA)
certified the updated high-pressure turbine (HPT) hardware
durability kit for the CFM LEAP-1A engines that power AirAerospace
& Defense Technology, February 2025
bus A320neo family aircraft. The durability kit was designed
to increase time on wing, especially in hot and harsh environments,
and includes the HPT stage 1 blade, HPT stage 1
nozzle, and forward inner nozzle support.
" This new hardware is fulfilling our promise to ensure that
LEAP-1A engines achieve the same level of maturity, durability,
and time on wing that our customers have enjoyed with the
CFM56 product line, " said Gaël Méheust, President and CEO at
CFM International.
