CHAPTER III
CHARACTERISTICS AND REQUIREMENTS
In a service submarine it is essential that it be capable
of keeping to the sea and making headway in any kind of
weather. This is at once evident for a submarine intended
to go to sea. There is at the present time a tendency to
divide submarines into two classes, namely, coast defense
submarines and sea-going submarines. However, it is
obvious that to be of any military value, even in the
smaller craft intended for coast defense work, it is just as
essential that it be able to venture outside the mouth of a
protected harbor in stormy weather as it is for one of the
larger sea-going boats, for it is at such a time that an in-
vading fleet of the enemy is most likely to make an attack.
In connection with sea-worthiness it is just as necessary
that the submarine be absolutely controllable in any kind
of weather, both when upon the surface and when running
submerged, and it is obvious that stability is a necessary
factor in obtaining both of these characteristics, as it is
also evident that safety is to a great extent dependent upon
the presence of all these qualities. As the tactical value
of a submarine torpedo boat as an offensive instrument of
naval warfare depends entirely upon its ability to go upon
long and extended cruises far from any friendly base, and
unattended, the supreme importance of these qualities
is apparent.
In spite of much that has been said to the contrary,
controllability is a quality wofully lacking in service
