A startup founded by veterans of the US Navy is set to revolutionize how the US military interprets underwater data using artificial intelligence. Spear AI, based in Washington, has successfully completed its initial round of external funding. The company is focused on passive acoustic data, which is collected through underwater listening devices. Their goal is to leverage AI to help submarine operators distinguish between various underwater sounds, such as rain squalls, whales, or potentially threatening vessels, and to accurately determine their location and speed.
