A little more detail added to Carthaginain's post:
688 - Original LA Class, standard boat, 4 tubes amidships, fiberglass sail, AN/BQQ-5 SONAR Suite and TB-16 Towed Array.
688 Flt II - adds VLS tubes, TB-23 Towed Array, Anechoic Tile, otherwise similar
688 Flt III/688(i) - VLS tubes, AN/BQQ-10 SONAR and TB-29 Towed Array, Anechoic Tile, External 6" Countermeasures pods in addition to the internal 3" countermeasures, bow planes instead of fairwater planes, under-ice capable.
Incremental quieting and fire control improvements made throughout the classes and flights. Biggest improvement in the Flt III is the AN/BQQ-10 which is a significant improvement of the AN/BQQ-5. How much I can't say, as I signed an NDA when working at SUBSCHOL, New London. Don't want to pay the 2.5 Million Dollar fine and spend up to 25 years in prison.
