A Very Informative Arcticle on Russian SSBNs Including Variants of the BOREY Class
Takes some digging but useful information confirmed includes use by BOREY Class SSBNs
of the GTZA-9VM turbine/gear propulsion module first developed in the very late 1970s
for the AKULA, and also installed on all OSCAR, TYPHOON and SIERRA Class units. What
you may remember about TYPHOON is not correct.
