Ship project history: Unique USN purpose-built minelaying submarine. Naval management offered to raise displacement for providing necessary in conditions of Pacific theatre endurance, and in some cases it wore enough absurd character: so, "monster" figured in one of sketch design with 20500t displacement. Finally Bureau of construction has prepared in 1922 basic design with surface displacement hardly more than 2500t, armed by two 152/53mm guns of cruiser calibre, four bow TTs and two mine tubes in a stern for 60 mines, should make self-sufficiency of 90 days, and an endurance at a full fuel stowage 18000nm. The hull of future Argonaut has been calculated for a diving depth of 95m instead of 60m at previous classes. At designing, besides usage of some technical decisions applied on S and Barracuda classes submarines, Americans have probably full considered the German experience of building of submarine cruisers in days of the First World War. In particular, on early design stages a fore end was planed to fulfil with characteristic bulb-shape stem as on Barracuda, but in final variant the characteristic sharp "German" bow figured.

Double-hulled, machinery was of combined type (main diesels directly connected with shafts and auxiliary diesel-generators for recharging batteries). To advantages of this submarine it is possible to refer, perhaps, only endurance and good conditions of habitability (that, however, for three-monthly voyage is important). In remaining submarine was mediocre enough: she had bad manoeuvrabiliy and slow speed.

Modernizations: 1930s: + JK sonar

1940: diesels were replaced by more powerful Fairbank-Morse (6000 h. p., 15 kts surfaced); - SC sonar: + QCD sonar

9/1942, Argonaut was converted to cargo submarine, mine deck and spare torpedoes compartment were rebuilt as cargo holds; + SD, SJ radars

Naval service: 10/1/1943 Argonaut was sunk by Japanese destroyers Isokaze and Maikaze between Bougainville and New Britannia.
