American Boat Speedier, Has
Greater Radius and Is More
HabitabIe.
RESULT or RECENT TESTS
Direct Comparison ls Made With Sub
marines of Latest German Type
Good Accommodation for Off
GERS and Crew.

Washington Elaborate tests car
rsed on by 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 to the German U-boat.
The American boat Is speedler, 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. OF the characteristics Of
the two types the navy department
says in an authorized statement:
'New and interesting light is thrown
on the efficiency of the German subma-
rines by recent tests conducted by Of
.fcers in the bureau of construction
and repair.
IAN opportunity recently developed
I'm this country which permitted d.
rect comparison between a late design
of German submarine and late design
of American submarine. While details
of the comparative tests cannot be CIV
en-, sufficient information is available

Ority of the German submarine.
Given Special Trials.
"As Is well known, i've German sub
marines of the latest design were
Brought TO the United States for use
an the Victory loan campaign. Four of
these boats came over under their own
power, manned by officers and men of
khe United States navy. The propul-
sive machinery of the fifth was par
TALLY destroyed or removed, so that 1t
was necessary to tow the vessel across.
'@The best of these German boats
was tuned up for special trials. When
reported ready for these trials spe-
ciaI 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 ut the
Germania yard, Kiel, Germany (com-
plcted in 1879, and SO, 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 300
ton class U-111 having a surface dis
placement of $50 tons and SO a sur
face displacement Of S54 tons.
Elm the trials the maximum surface
speed of the U-111 was 1873 knots, while
the So made 14.7 knots. The sub
merged speed Of the U-111 was rs
Knots, while SO made 12.4-a remark
able difference in favor of 49, The
radius of action OF the two boats is
also in favor Of SO, despite all the
Juror that was created By the advent
OF the German U-boat on American
coasts during the war.
~U-111 can cruise $500 miles at
Knots, while SO can cover 10000 miles
nj II knots. The submerged cruising
radius shows an equal prepOnderanco
In favor OF SO. Both boats can carry
II torpedoes. U-111 mounts two 4
inch guns, one forward and one aft
SIS mounts one 4-inch gun forward
iris practice of one gun on a subma
rine being standard practice In the
United States navy.
