On 13 September 2008 LEDET 404 deployed aboard seized a self-propelled, semi-submersible (SPSS) vessel west of Guatemala during a nighttime boarding. The SPSS had been detected by a U.S. Navy patrol aircraft which vectored "McInerney" towards the vessel. "McInerney" launched two small-boats to interdict the vessel and LEDET 404 boarded the vessel under cover of darkness effectively surprising the crew. Upon realizing that they were being boarded, the smugglers first tried to throw the boarding team from the vessel by rapidly reversing the engines and then opened seacocks to scuttle the vessel but then complied with the boarding team’s orders to close them again. The vessel was found to be carrying seven tons of cocaine.
