On September 17, the U.S. Navy launched two unarmed Trident II D5 Life Extended (LE) submarine-launched ballistic missiles (SLBM) in a scheduled flight test in waters off Cape Canaveral, Florida. The missiles, launched from Ohio-class submarine USS Wyoming (SSBN-742), landed in the Atlantic Ocean within the U.S. Eastern Test Range instrumented complex. The launches mark the 184th successful test of the Trident II SLBM.
