Navy P-3 Orions working with Coast Guard teams have spotted two of the self-propelled, semi-submersible (SPSS) craft

Navy P-3 Orions working with Coast Guard teams have spotted two of the self-propelled, semi-submersible (SPSS) craft trying to make their way from Colombia up to the west coast of the U.S. in the Pacific ocean. Intelligence helped them know where to look.Rear Adm. Ted N. Branch says the Navy P-3 Orions used in the interdictions have radar and forward looking infrared sensors that can detect these low profile SPSS craft on the ocean.These types of smuggling vessels are fabricated in the jungles of Colombia and designers have moved on from earlier wood and fiberglass models to steel and fiberglass. Their low topside profile creates a small radar cross section, so maritime patrol aircraft have the best detection track record so far, according to the Coast Guard.On Sept. 13, a Navy P-3 Orion directed a U.S. Navy warship to one SPSS so a Coast Guard team could board the vessel. The boarding party surprised the four Colombians aboard, who then opened valves to scuttle the vessel. The Coast Guard crew was able to get the valves closed, allowing the 59-foot long SPSS and seven tons of cocaine to be seized.In the other case on Sept. 17, the P-3 directed the Coast Guard cutter Midgett to an SPSS 400 nautical miles south of the Mexico-Guatemala border in the Pacific. Seven tons of cocaine valued at $196 million were seized, but the SSPS sank after the drugs were removed.
