sho" that Inc latest type of American
submarine is superior in nearly every
respect to 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. 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
ncers in the bureau of construction
and repair.

Given Special Trials.
"As is well known. five German sub
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
tally destroyed or removed. so that 1t
was necessary to tow the vessel across.
1.-THE best of these German boats
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 1879 and SO. submarine
designed by the navy department; S-3
was built at the Portsmouth navy yard
and was commissioned In 1918.
These boats both belong to the 800
ton class U-111 having surface dis
placement of $50 tons and SO a sur
face displacement Of 354 tons.
'In 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 S-3 made Pa remark
able difference in favor of So. 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
at II knots. The submerged cruising
radius shows an equal preponderance

ct is necessary to really live in these :.
vessels to appreciate the radical diff
ference in their habitability, vital
military characteristic. for subma-
rine is no better than its crews.
