USS Hawkbill (SSN-666), a Sturgeon-class attack submarine, was the second ship of the United States Navy to be named for the hawksbill, a large sea turtle. The name perpetuated the inadvertent misspelling of "hawksbill" in the naming of the first ship of that name, USS Hawkbill (SS-366), a Balao-class submarine launched in 1944. USS Hawkbill (SSN-666) was the eighteenth of 39 Sturgeon-class nuclear-powered submarines that were built.

The Sturgeon class was a class of nuclear-powered fast attack submarines (SSN) in service with the United States Navy from the 1960s until 2004. They were the "workhorses" of the Navy's attack submarine fleet throughout much of the Cold War. The boats were phased out in the 1990s and early 21st century, as their successors, the Los Angeles, followed by the Seawolf and Virginia-class boats, entered service.
