200603-N-NU281-1050 PACIFIC OCEAN (June 3, 2020) Sailors assigned to the Los Angeles-class fast-attack submarine USS Chicago (SSN 721) prepare to launch an Encapsulated Harpoon Certification Training Vehicle (EHCTV) for testing. Chicago is conducting EHCTV testing which allows the submarine to carry and employ a tactical Harpoon. The Harpoon system provides commanders with lethal all-weather anti-ship capability to rapidly engage targets at long range. (U.S. Navy photo by Mass Communication Specialist 2nd Class Justin R.
