USS Chehalis (PGM-94)

USS Chehalis (PGM-94/PG-94) was an Asheville-class gunboat of the U.S. Navy and the second ship to be named Chehalis. Chehalis was launched 8 June 1968 at the Tacoma Boatbuilding Company. She was commissioned 8 November 1969. The vessel was named in honor of Chehalis, a city in Washington state. Later, she was transferred to Naval Sea Systems Command and renamed Research Vessel Athena. Athena was scrapped in 2016.

The Chehalis was powered by a combination of two Cummins diesel engines and a General Electric LM-1500 gas turbine. Pneumatic actuators allowed the power source to be switched between the two sources.
