}} | MV Cory Chouest is an ocean surveillance ship leased by the U.S. Navy in 1989 and assigned to the Navy’s Special Missions Program. Cory Choquest had all SURTASS equipment removed and was returned to her original owners in 2008 completing nearly 20 years of service.[1]ConstructionCory Chouest was acquired and modified by Edison Chouest Offshore for use by the U.S. Navy as a modified TAGOS vessel. Originally used as a research platform in conjunction with the {{MV|Amy Chouest||2}}, the Cory was later modified to carry an active and passive sonar system. The vessel served until October 2008 when it went off charter. Mission The mission of Cory Chouest is to directly support the Navy by using both passive and active low frequency sonar arrays to detect and track undersea threats. Operational historyIn January 1991, the Cory Chouest and Amy Chouest were used as part of the Heard Island feasibility test, an experiment to transmit low frequency sound through the ocean from Heard Island in the Southern Indian Ocean[2] as far as both ocean coasts of the US and Canada.[3] The Cory Chouest was chosen because of its central moon pool and because it was already equipped with an array of low frequency transmitters. A phase-modulated 57Hz signal was used. The experiment was successful and demonstrated that such sound waves could travel as far as the antipodes. Planned transmissions had been for ten days, although owing to the bad weather conditions and the high failure rate of the transmitter elements, used at a frequency below their design frequency, the transmissions were terminated on the sixth day, when only two of the original ten transducers were still working.
