Only 35 left in service

As of 2018, 35 of the class are still in commission and 27 are retired from service. Of the 27 retired boats, 12 of them were laid up half way (approximately 20 years or less) through their projected lifespans,[1] and another five also laid up early (20–25 years), due to their midlife reactor refueling being cancelled, and one was lost due to a fire. Seven have been scrapped and two are being converted to moored training ships
