Trabajador was a 111 foot (33.8 m) tug launched in 1931 from the Hong Kong and Whampoa Dock for Visayan Stevedore-Transportation Company and registered as a United States vessel in Iloilo, Philippines.

[1] In 1935 the Trabajador took part in a rescue of survivors from the British freighter Silver Hazel that was wrecked in San Bernardino Strait.

[2] Trabajador, assisted by the USS Finch, dumped unused mines into Manila Bay as Corregidor came under air attack on 29 December 1941 and continued the operation through the next day.

[2][5] For a brief time she was the "luxury" vessel for the PTs with a real galley, wardroom and a mess boy who baked pies.

[8] Trabajador was sunk on 10 April 1942, most likely by Japanese artillery near Corregidor, and was awarded a battle star.
