One of Seasats autonomous surface vessels (ASVs) has reached Japan after completing a fully autonomous trans-Pacific voyage, marking a breakthrough in persistent, low-logistics ASV operations.

Lightfish ASVs are 12-ft., 350-lb. solar-powered vehicles that have been in use with U.S. Navy and commercial customers around the world since early 2023.

The transit launched from the company’s headquarters in San Diego, stopped in Hawaii for a demo, took pictures on its way past Wake Island and Guam, participated in another demo in Okinawa, and finished its journey in mainland Japan.

In total, the Lightfish traveled more than 7,500 mi. over 150 days. Throughout the voyage, people followed along via a publicly accessible tracking page displaying a 24/7 ocean intelligence feed, including key boat health metrics, nearby vessel tracking via AIS and cameras, and live video of fish swimming alongside the ASV.
