ton of the shore and the attacking
planes stay at an altitude of at least
1000 feet. Eight o'clock in the morning
will be 'zero hour
In the test against the Iowa all avail
able naval aircraft will be used, inclnd-
ing at least four dirigibles. Under pres
ent plans the army will not use any land
planes in this test, but the naval detach-
ment will include four Martin bombers
assigned to the Marine Corps. 1t Is ex-
pected that more than one hundred air
craft will take part in the search Tor any
bombing OF the Iowa. Dummy bombs
ranging from 230 to 1000 pounds each
will be used. The army personnel in
volved will fly ~eaplanes.
Data on Hits wanted.
AS soon as contact is made by any OF
the scouting aircraft a radio signal Will
be sent out and reserve planes held at
the Hampton Roads. here and at Langley
Field will form In division and rush to
the attack. Destroyers will be stationed
in long lines along the coast in the gen
eral vicinity of the test to go to the res
cue of planes forced down into the water
Live bombs will not be used in the
experiment, as the navy wishes to pre-
serve the Iowa, the only radio controlled
battleship in existence, for target prac-
tice with the Atlantic fleet next fall
The problem In the air tests Is designed
to furnish reliable data on the probable
number of hits to be expected from air.

tests will take place on July 13 with
the former German destroyer G-102 as
the target. The army will make the
first attack, using twelve Martin bombers
and eleven DH-4 machines and 2b0
pound bombs, ninety-four OF which VIII
be dropped. The conditions Of the attack
are left at the discretion of flight COM
manders. If the destroyer is not sunk
by the army's attack the naval air de-
tachment will attempt to sink the YES

it will be sunk on the following day
by gunfire by Atlantic fleet destroyers,
along with the former German Destroy
ers S-132 and V-43. Should the de-
stroyers fail to sink the vessels battle
ships will be assigned to the task.
Fourth Phase ON July Is.
An attack on the former German
cruiser Frankfurt will be the fourth
phase OF the tests and is set Tor July
Is. The vessel, completed In 1913, TOOK
prominent part in the battle of Jutland
and represents a good type of modern
cruiser. She will be at anchor during
the attack and the attacking aircraft,
consisting of army and navy planes
flying in mixed formation, will use frst

and 6Oe pound missiles. All types OF
aircraft will be used. the first attack
to take place at 8 o'clock in the morn
ing. II the vessel remains. afioat after
the final attack IL will be sunk by
destroyers at range of 5000 yards.
The final test In the series thus Tar
arranged will be the bombing OF the
former German battleship Ostfriesland
on July 20. The Ostfriesland is dread
nought of 22,S00 tons, mounting lZ-incn
guns, and was surrendered to the Al
lies at Scapa Flow. During tne oattie
of rutland she formed part OF the Ger
man first battle squadron ana was paoAy
damaged by q mine.
The principal value of the Ostfriesland
experiment Is expected to be the result

age aerial bombs may be expected 10

be attacked by army and navy aircraft.
The conditions Of the test require three
hits each with 25o and 500 pound bombs,
two hits with the $50 and 500 pound
types and at least two hits with 1000 OF
1000 pound projectiles. There wm De
provided for use in the attack thirty-two
OF the 1000 pound bombs and three OF
the 1000 pound type.
IL the Ostfriesland remains afioat after
all the required hits have been made
the vessel will be used as target for
the main battery Of the battleship Penn
sylvanla, flagship Of the Atlantic fleet,
as all the German ships were turned
over to the United States on condition
that they be destroyed within q year.
