  They stopped using black powder in large naval guns before the turn of the
century.  They've been using cordite ever since.  The cordite propellant is the
reason why magazine explosions in most ships produces very intense, bright, high
(~1000 feet high during the explosion of HMS Hood) flames and voluminous clouds
of brown smoke.
  Initially, the cordite manufacturers used vaseline as a solvent for the 
cordite, but the presence of the solvent actually destabilized the cordite to
the point where slightly inadequate magazine refridgeration could cause 
spontaneous explosion of the cordite charges in the magazines.  France lost the
battleships Iena and Liberte in 1907 and 1911 to precisely this type of 
disaster.  Sometime before World War One, the Germans developed solventless 
cordite, and other nations began to follow that lead after the war was over.
