Biggest US Submarine
Yes, in terms of tonnage and length, the USS Argonaut (SS 166) was the largest US sub of WWII, although the Narwhal class (Narwhal and Nautilus) was only slightly smaller. The Argonaut was indeed sunk (but in 1943, not 1942 I think) - the Narwhal (SS 167) and Nautilus (SS 168) survived the war and were scrapped soon after. None of these three subs will be included in SHIV.
