However, it has plans to field many more and a
new report from the U.S. Government Accountability Office notes that the Navy
faces several challenges on RAS deployment.
Recent conflicts in Ukraine and the Middle East prove that robotic and
autonomous systems (RAS) are disrupting naval warfare and challenging traditional
naval superiority. To provide more adaptable, dispersed operations, the Navy
intends to shift away from its World War II-era operating model, which was
based on closely knit battle groups comprised of several traditional platforms,
such as planes, ships and submarines.
According to Navy strategic documents, a hybrid fleet is necessary to
enable this shift and would incorporate smaller, more numerous, and distributed
capabilities—including RAS capabilities—as a complement to larger, more
individually powerful, traditional capabilities. In this context, RAS
capabilities could allow naval forces to take on greater operational risk while
maintaining a tactical and strategic advantage. The Navy plans to spend
billions of dollars on researching and developing enabling technologies for RAS. In March 2025, GAO found that the Navy had not taken steps to address
key challenges to developing RAS capabilities quickly despite critical needs
for RAS implementation. For example:Inconsistent
leadership and priorities impeded RAS investments. Inconsistent senior
leadership and shifting priorities impeded the Navy’s progress establishing an
organizational structure for RAS and making efficient investments to achieve
goals. Domain- and platform-centric
approaches impeded progress of RAS. Without consistent leadership to advocate
for RAS investments, the Navy’s organizational structure and processes for
requirements, resourcing, and acquisition generally remained siloed by domain
and focused on traditional platform approaches. Under this approach, RAS
compete for resources with traditional ships, submarines, and aircraft
carriers—many of which are priority major weapons acquisition programs—leaving
little funding available to develop and field RAS.
GAO says that iterative approaches could accelerate
RAS development. Commercial companies are driving a rapid pace of RAS
development that greatly outpaces development timelines of traditional Navy
platforms. In 2021, Navy leadership published the Unmanned
Campaign Framework to address
organizational barriers and adapt its development processes to expedite
development of RAS capabilities. The
framework identified a desired shift to development processes to expedite
development that could help the Navy promote iterative development approaches
in line with leading practices. However, as of March 2025, the Navy had yet to
implement these changes. Portfolio
management and formalized stakeholder roles could improve coordination. To
better position itself to get RAS capabilities to the warfighter with speed,
GAO found the Navy needs to optimize investments in RAS and enabling
technologies by managing RAS capabilities as a portfolio. Navy officials also
told us a lack of formalized RAS stakeholder responsibilities continued to
create inefficiencies and confusion.
Without rapid action from the Navy’s most senior leaders to address
these challenges, says GAO, the Navy risks not meeting the fleet’s urgent
needs.
GAO made three
recommendations to the Secretary of the Navy and the Chief of Naval Operations
and noted a matter for Congressional consideration. Determine how to organize RAS
capabilities as a portfolio in a way to provide consistent leadership and meet
the Navy’s objectives across warfighting domains; Develop and implement a plan
to facilitate capability-centric approaches and iterative development
approaches after establishing an organizational structure of the RAS portfolio;
and Clearly identify and define the roles and responsibilities of key
stakeholders for RAS and develop a stakeholder management plan.
Congress should
consider amending the provision of the William M. (Mac) Thornberry National
Defense Authorization Act for Fiscal Year 2021 to allow the Navy to designate
the role of the Acquisition Executive Agent for Autonomy to appropriate
leadership with authority that matches the responsibilities of the position,
without restriction to a Program Executive Office.
