San Diego California Sub Art. Naval Base San Diego, sometimes called 32nd Street Naval Station, is one of the largest United States Naval bases, and is located in San Diego, California. Naval Base San Diego is the principal homeport of the Pacific Fleet, consisting of 50 ships and over 120 tenant commands. The base is composed of 13 piers stretched over 977 acres of land and 326 acres of water. The total on base population is 20,000 military personnel and 6,000 civilians. The Los Angeles class (also known as the 688 class) is a class of nuclear-powered fast attack submarines. They represent two generations and close to half a century of the U.S. attack submarine fleet. As of late 2015, 39 of the class are still in commission and 23 retired from service. Of the 23 retired boats, 14 of them were laid up half way (approximately 17–18 years) through their projected lifespans due to their midlife reactor refuelings being cancelled.
