the largest submarine squadron in the US Navy, with six Los Angeles-class nuclear fast attack submarines assigned, to include , , , , , and . Toti's final active duty assignment was to establish and serve as the first commanding officer of Fleet Antisubmarine Warfare (ASW) Command, Norfolk, Virginia. During this tour, in 2005 Toti authored a new maritime doctrine titled "Full Spectrum ASW." Widely regarded as a sea change in the method by which naval forces countered submarines, his treatise on the subject also received wide attention internationally. During this assignment, Toti was also called upon by the Navy to defend the use of active sonar for antisubmarine training, arguing for the practice during controversial public hearings near populations affected by the beaching of marine mammals. Exoneration of Captain McVay While serving as commanding officer of the submarine USS Indianapolis (SSN-697), Toti was recruited by the survivors of the World War II cruiser USS Indianapolis (CA-35) to assist in their effort to clear the name of Captain Charles B. McVay III, who was captain of the cruiser at the time it was sunk by Imperial Japanese Submarine I-58, and who had been court-martialed following their ship's sinking. In response, Toti authored the article on the McVay affair, titled The Sinking of the Indy and the Responsibility of Command published in the US Naval Institute Proceedings in October 1999. Later Toti helped Admiral Donald Pilling prepare his testimony in front of a US Senate committee hearing on the McVay court-martial. McVay was exonerated in 2000. Toti's role in the McVay affair was described in the books In Harms Way by Doug Stanton and Indianapolis by Lynn Vincent and Sara Vladic. As a result, Toti was named an Honorary Survivor by the USS Indianapolis Survivors' Organization in 2005. Toti's role in helping to clear McVay's name was covered in the 2016 documentary film USS Indianapolis: the Legacy Project, directed by Sara Vladic. The documentary won several awards at GI Film Festivals in both Washington, DC, and San Diego, California. In September 2017, Toti was also featured in a PBS live broadcast titled USS Indianapolis, Live from the Deep, and in 2019 he was featured in the PBS long-form documentary USS Indianapolis: Final Chapter.
