Liberty 1 (HTMS Pattani) is one of three wrecks commonly referred to as "The Liberty Wrecks".
HTMS Pattani is a torpedo boat, Trad Class built in Monfalcone shipyard, Trieste, Italy.
There is some confusion surrounding her official designation. USA and some French documentation refer to her as the HTMS Chantaburi (จ.บ.) with the old number "11" HTMS Trad. It is believed the number and abbreviated name were erased during Franco-Thai conflict (source: http://www.navy.mi.th in Thai language).
Trad class boats were name after Thai coastal provinces. Thai navy called these ships "large torpedo boats".
The most recent designation for this ship is "13"
