Boeing, the aerospace giant, has hit a major milestone with the delivery of the inaugural Orca Extra Large Unmanned Undersea Vehicle (XLUUV) to the US Navy in Huntington Beach, California.

Dubbed XLE0, this cutting-edge autonomous submarine is at the vanguard of next-generation technology, designed to transform undersea operations and strengthen the nation’s maritime superiority.

Pioneering the Future of Undersea Warfare

The XLUUV is a leap forward in autonomous submarine technology, designed for extended undersea endurance missions, and represents a significant boost to the Navy’s capabilities in complex and changing maritime environments.

At 51 feet (around 15.5 meters), the XLE0 boasts a diesel-electric hybrid engine and a modular payload section, allowing for a wide range of mission-specific tools and systems.

Captain Scot Searles, US Navy Unmanned Maritime Systems Program Manager, lauded the delivery as a milestone born from years of dedication, marking the Navy’s first foray into deploying unmanned diesel-electric submarines.

“This has been a very busy year for the XLUUV team and their hard work is culminating in delivery of the Navy’s first-ever unmanned diesel-electric submarine,” said Searles in a press statement.

He anticipates further success in partnership with Boeing, enhancing the Navy’s operational capabilities.

Evolution of the Orca XLUUV

The transfer of the XLE0 follows the successful completion of its acceptance tests earlier this month.

The comprehensive in-water trials, including extensive above and below-surface maneuvers, commenced in the spring of 2023, solidifying the platform’s operational readiness.

Developed by Boeing, the Orca is part of a broader US Navy initiative to extend its operational reach and versatility without risking human lives.

The development of the Orca XLUUV stems from Boeing’s earlier work on the Echo Voyager, an autonomous submarine designed for extended, deep-sea missions.

The Echo Voyager, announced in 2012, itself was an evolution of Boeing’s earlier Echo Seeker and Echo Ranger vehicles, incorporating lessons learned from these projects into a larger, more capable platform.

The Echo program has amassed an impressive track record, encompassing over 10,000 hours of autonomous operations and traversing “hundreds of nautical miles.”

In 2017, Boeing was awarded a contract under the Navy’s XLUUV program to produce the Orca, designed to operate autonomously for extended periods, with a modular payload bay capable of carrying various mission-specific tools, including sensors and weapons.

Its development has been marked by a series of rigorous tests and demonstrations designed to prove its capabilities in realistic operational scenarios.

The insights gained from these milestones have been pivotal in advancing the Orca XLUUV program through its successive stages of development and refinement.

Decades of Dedication and Technological Mastery

Ann Stevens, Boeing’s Vice President of Maritime and Intelligence Systems, stated in a press statement:

“This is the culmination of more than a decade of pioneering work, developing a long-range, fully autonomous undersea vehicle with a large payload capacity that can operate completely independently of a host vehicle.”

Stevens lauded the unparalleled commitment, innovation, and perseverance exhibited by the team, which resulted in the creation of the world’s most advanced and capable Unmanned Undersea Vehicle (UUV).

Stevens further underscored Boeing’s commitment to furthering the collaboration with the Navy, striving to continually enhance and deliver this groundbreaking vehicle, poised to redefine maritime operations.

“I’ve had the distinct pleasure of witnessing our team bring this first-of-its-kind capability to life, and I’m proud of their innovation, perseverance, and unwavering commitment, which has yielded the most advanced and capable UUV in the world,” she added. “With the Navy’s partnership, we look forward to continuing to deliver this game-changing vehicle to the fleet.”

The handover of the Orca XLE0 is not just a delivery; it’s a significant leap in autonomous undersea technology.

It represents the culmination of relentless innovation, strategic partnership, and a shared commitment to redefining undersea warfare.

Boeing and the US Navy’s collaborative efforts have paved the way for a new era of maritime operations, ensuring a robust, adaptable, and technologically advanced naval force ready to face the challenges of the future.

This landmark delivery symbolizes a commitment to national defense and the continuous evolution of maritime capabilities.
