Key Takeaways

Autonomous ships are those ships and vessels that include some level of
autonomy. Such ships range from crewed ships with automated processes and
decision support to ships that can make decisions and determine actions without
human involvement. These ships have technologies that can allow them to
autonomously navigate, avoid collisions, control the speed and direction of the
ship, or communicate with other ships. Autonomous ship technologies are
developing quickly-domestically and abroad-and have the potential to
transform the maritime environment. While autonomous ships offer a range of
potential benefits, these new technologies also pose new safety risks that could
present challenges to a U.S. legal framework that requires crews to be onboard.
As autonomous ship technologies develop, some countries are pursuing various
approaches to regulating them. In the U.S., the Coast Guard is the federal
agency responsible for regulating U.S. waterways to ensure that they are safe
and secure. This includes promulgating regulations and guidance pertaining to
the design, construction, and operation of commercial ships; certifying their
compliance with applicable laws and Coast Guard regulations; and issuing and
administering the credentials of seafarers. The Coast Guard is currently
conducting a statutorily directed pilot program for autonomous at-sea rocket
recovery that began in 2023. The Coast Guard acts as the lead agency within the
U.S. delegation to the International Maritime Organization (IMO)-a specialized
agency of the United Nations with the responsibility for the safety, security, and
environmental performance of international shipping.
The fiscal year 2023 National Defense Authorization Act includes a provision for
GAO to submit a report on, among other things, how commercial autonomous
ships are used, how they may affect safety and the maritime workforce, and how
these ships are regulated internationally and domestically. (Pub. L. No. 117-263,
§ 115040), 136 Stat. 2395, 4133-34 (2022)). This report describes commercial
autonomous maritime ship usage globally and the associated benefits and
challenges, how the IMO and selected countries are regulating these
technologies, and how the Coast Guard is regulating autonomous ships and the
challenges it may face in the future.
Although the potential for autonomous ships is broad, current commercial
uses are fairly narrow. According to the IMO, all current uses should have a
human who is in control or can take control if needed. U.S and international
stakeholders we interviewed described improved safety and efficiency,
among other benefits. However, some expressed concerns and noted
challenges involved in developing and proving these technologies for safe
commercial use. Additionally, uncrewed or fully autonomous ship
technologies may pose new safety risks in the maritime environment and
