VESSELS OF new
TYPES BUILDING
Navy To Have Aircraft Car
riers And Cruiser.
Submarines

Washington, Dec. 25.-Among the
140 vessels under construction fol
the navy are four types new to the
American battle fleet, but long in use
by the other principal maritime pow.
ers They are the battle cruiser, oil
which six are being built, the scout
or light cruiser, the airplane carrier
and the fleet submarine.
The battle cruisers will be of great
speed, light armor, long cruising ra-
dius and strong offensive armament
the ships being designed primarily
for ranging work ahead of the main
body and for action at long range
against vessels of their own class.
They are to have speed of slightly
more than thirty-three knots (about
forty miles) an hour and will carry
eight 16-inch guns mounted two in a
turret.~
The ten light cruisers also will
function as scout cruisers. They will
have speed or thirty-three and sew
en-tenths knots and will carry an ex-
ceptionally heavy armament for YES
sells of their class, mounting twelve
six-inch guns. They are designed to
develop 10000 horsepower, half that
of the battle cruisers.
Aircraft Carrier Interesting.
One of the most interesting of the
new types is the aircraft carrier
Langley, formerly the collier Jupiter.
This vessel is being built along the
line of the general boards policy that
aircraft carriers should be combatant
vessels whose speed and other char
acteristics will permit Of their use
with the fleet at sea. The Langley
will carry in the neighborhood of fiji
teen planes of both the sea and mill
tary scouting types. The ships fly
ing deck will consist of huge plat
form, fifty-six feet above the water
line, extending from bow to stern, a
distance of about 525 feet and with
an amidships width of sixty-five
feet. The planes will be housed be-
low on the hangar deck when not in
use and will be carried to the flying
deck in elevators. Catapults will be
provided on the flying deck to pro-
ject the planes into the air and give
them the necessary momentum for a
start. Arresting devices will be rig
ged on the flying deck to permit of
landing directly ON the deck while
the Langley is under way. while huge
cranes will also be installed to pick
planes out of the water.
Beneath the flying deck other
travelling cranes will be provided to
hoist aircrafts out of the hold spaces
and for carrying them to machine
shops, assembling spaces and to the
elevators. Shop facilities for repairs
will include completely equipped
machine shop, wing repairing shop,
molding spaces "a metal shop, and
various storerooms.
An ingenious method for providing
smoke pipes without breaking the
flying deck area is devised for the
Langley. The ship will have two
smoke tunnels, one on each side clear
Of the flying deck and inter-connected
so that the smoke may always be dis
charged on the lee side and thus not
interfere with the landing or dis
charge of aircraft.
New Types Recommended.
The fleet submarines building num-
Der six. Six others authorized have
not yet been contracted for. Their
principal characteristics will be a long
cruising radius. enabling them to ac-
company the fleets under practically
all conditions, and new structural de-
signs to make them as nearly as pos
sible proof from depth charges. The
submarines will be over 800 feet long
with a displacement of about 2,0O0
tons. The propelling machinery for
surface cruising will be two main
Diesel engines aft The other Diesels
forward will drive electric generators
which will provide current for the
two main electric motors to propel
the submarines when submerged. The
estimated surface speed is twenty
knots and the submerged speed is ten
knots
In addition to these new types,
Secretary Daniels and the general
board have recommended the con-
struction during the next three years
Of three other types heretofore I'M
known In the United States navy,
They are the destroyer leader. long
range cruising submarines, and mine
