 USS Simpson, the last of the Oliver Hazard Perry class frigates, was decommissioned September 29th, marking the end of an era for our Navy. Well, I think the frigate is one of a kind platform. I wouldn't say it's irreplaceable because I think we have enough other ships in our arsenal that we can meet the missions, but it's going to be really hard to replace because it was such a versatile platform. Built in 1984, this 30-year-old vessel was the last modern warship to sink an enemy during battle. The Simpsons sank Iran's Joseon gunboat in the Persian Gulf in 1988, in the only maritime battle since the Second World War. For more information about Simpson, visit navy.mil.
