The consortiuum of Testors/Italieri re-released some of the 1:700 scale DML/Dragon subs under their label. I know of the Los Angeles and the Ohio, eached paired with a Soviet adversary sub. I don't specifically remember a Sturgeon by Testors/Italieri, but I do remember it by DML. I built one whole hull and another surfacing through the icepack.
Being a submarine, and at their small scale size, there isn't a whole lot of detail provided in the kit. You need to replace the prop one of Flagship Model's PE scimitar-blade props and, since your dad was a sonarman, complete the towed array deploy tube out the stern.
JAG Collective makes a resin 1:700 scale Sturgeon - as a waterline only kit. No PE - none is needed since it only has those things which are above the water when surfaced. The JAG kit also has a 1:700 scale DSRV included as these were carried by some Sturgeons.
The YankeeModelworks (ex Blue Water Navy) Sturgeon is a nice kit. A PE prop is included as are white metal periscopes & masts. The YMW kits make into nice display models of a decent size with a minimum of effort.
