 "The notable feature of the AKULA class is a large streamlined pod
  on top of the vertical tail fin.  The official judgement is that it 
  probably contains a towed sonar array.  Others have speculated that 
  a new type of auxiliary propulsion system, based on magnetohydrodynamics 
  (MHD), is involved."
