U23C Phases

GE used a common body for the various U-boats, so this list is based on phases of the U30B.

Phase II with the forward radiator intake mounted high had oil bath filters; low-mounted intake was for paper air filters.

Phase IIa- entire hood below the radiator is the same width as the radiator itself, radiator intakes are redesigned, the raised section on the radiator disappears, a horizontal drip rail appears on the sides of the radiator, short exhaust stack, small taper just ahead of the radiator, pipe chain guards at right front corner.

Phase IIb- the taper just ahead of the radiator disappears, six equipment doors on the left side instead of eight.

Phase IIc- the intake screens become corrugated instead of flat, and project slightly from the hood instead of being flush-mounted.

Phase IIh2- separate front headlight casing, hinges on front numberboards appear.
