Tom: I have a question regarding the Special ops version: Why did you omit the notorious protruding bow thruster motor? Was it removed sometime during her career as a Special Ops sub?
A single test thruster was installed on top of the hanger for a short time period in the late 1960's. It worked poorly. A much more useful set of thrusters were installed under the deck superstructure in a later overhaul, which also installed the mixed gas diving chamber for saturation divers. At no point was the old thruster atop the hanger on the boat while the diving chamber was on the upper stern deck casing.
The new thrusters are represented by two openings in the bow (one atop the other, forward of the dive planes) and two in the stern (side by side, near the end of the false deck superstructure, just under the diving chamber forward support strut). If you look carefully, they are on the Special Ops version model I built. I have several photos of Halibut with these thrusters, including a Hi Rez photo I obtained form the crew. The Spec Ops version of Seawolf (SSN 575) also got the same thruster outfitting. Instead of the "DSRV Simulator" (diver chamber), Seawolf was cut in half & a 53 foot long plug added.
