American Boat Speedier, Has
Greater Radius and Is More
Habitable.
RESULT OF RECENT TESTS
Direct Comparison Is Made With SUBJ
marines Of Latest German Type
Good Accommodation for OFF,
GERS and Crew.

iicu vi ny tHe navy department, the
results of which were announced by
Acting Secretary Franklin Roosevelt,
show that the latest type of American
submarine is superior in nearly every
respect t. the German U-boat.
The American boat Is speedier, has
a greater radius of action and is much
more habitable than the German boats.
Naval officers are of the opinion that
the American submarine is the more
seaworthy. or the characteristics of
the two types the navy department
says In an authorized statement:
New and interesting light is thrown
on he efficiency of the German subma-
rines by recent tests conducted by of
hcers in the bureau of construction
and repair.
AN opportunity recently developed
in this country which permitted q d.

of German submarine and a late design
Of American submarine. While details
of the comparative tests cannot be CIV

Given Special Trials.
"As is well known, FIVE German SUBJ
marines of the latest design were
brought to the United States for use
In the Victory loan campaign. Four of
these boats came over under their own
power, manned by officers and men Of
the United States navy. The propul-
sive machinery of the fifth was par

was necessary TO tow the vessel across.

was tuned up for special trials. When
reported ready for these trials a spe-
cial board was designated to conduct
the trials, following the established
practice In carrying out contract trials
for submarines Of the United States
navy. The boats compared were ex-
German submarine U-111, built at the
Germania yard, Kiel, Germany (cOm-
pleted in 1919, and SO, a submarine
designed by the navy department; SO
was built at the Portsmouth navy yard
and was commissioned in 1918.
These boats both belong to the 800
ton class U-111 having a surface dis
placement Of $50 tons and SO a SUR
face displacement of 854 tons.
an the trials the maximum surface
speed of the U-111 was 1873 knots, while
the SO made lat knots. The sub

of the German U-boat on American
coasts during the war.
"U-111 can cruise $500 miles at 8
knots, while SD can cover 10000 miles
at II knots. The submerged cruising
radius shows an equal preponderance
in favor of SO. Both boats can carry
II torpedoes. U-111 mounts two A.

SIS mounts one finch gun forward.

"It is necessary TO really live in these
vessels to appreciate the radical diff

Much has been written Of the sea-
worthiness of the German U-boat. An
opportunity to compare the seagoing
capabilities of the two vessels oc-
CURED during these trials, and the
general consensus of opinion among
the officers conducting the test is that
the SO is the more seawOrthy vessel.
Her decks are drier, her bridge less
subject to green seas and her general
behavior in a seaway superior.
Referring to the comparative liy-
ing capabilities of the two vessels and
general handling there are few differ
ences and those few appear to favor
the SD.
