group is composed of conversions and experimental
prototypes that bridge the gap between the irregular
shapes of World War II versions and the streamlined
sails of the nuclear age. If the sail topline is broken
and has an obvious step measuring one-fourth of the
group sail height or more, it falls within groups 7
through 9 (fig. 13-23), depending on the position of
the sail.
TYPES OF SUBMARINES
For the purpose of our discussion, we will
categorize submarines into three distinct groups:
attack, cruise missile, and ballistic. All three groups
can be either conventionally powered (diesel/electric)
or nuclear-powered.
