Of the dearly bought Lessons Of naval
wnrfare in the Moth Sea. a new en-.
CINE Of destruction Is coming--the
submarine destroyer Larger, more
powerful, and with a greater radius Of
operations than any Of It's predecessors,
this new wasp of the sea will not only
be equipped 70 sting its giant adver,
saries but TO destroy its own kind on
the surface Of the sea.
British and French navy Yards. and
private ship yards rs we'll, are work
ing night and day to have the new sub
marine DESTROYER in service within the
next few months. This information
coming to United States naval officers
commands greater interest because the
UniSed States navy, too, is to have
some OF these newest ships Of war. Its
experts have been at work npon plans
for them for months.
Theory Of Construction
The theory in which the new sea
fighters are being built Is that they
shall be armed for battle either on the
surface or below They will be Of
much greater tonnage then existing
submarines. Tentative plans have
been made for boats OF 1000 tons, sub.
merged, which would permit fuel ca.
pacity 70 cross oceans with battle
fleets and allow adequate provision for
crew quarters. The close attendance
of a parent ship npon submarine fleets
would then be unnecessary. g

Underwater EMERGENCY
Beneath the surface the new de
stroyers would operate as ordinary 200
ton vessels Of their type, except that
they would have greater cruising range
On the surface they would scout fol
hostile submarines, spotting an en-
envy periscope, then swinging M tn,

greater speed to keep in range and
