each of which will drop four bombs.
Il torpedo plane division OF five Mar
tin bombers. each of which win drop
six bombs, four NC type seaplanes.
each OF which will drop four bombs
and Marine corps division of six
OH planes TO let go two bombs each.
All of the bombs will be of the 163
pound type.
After the attack by the naval air
detachment If the submarine has not
been sunk, the army flyers will take
off from Langley Field. The army
flight will consist of twelve big Mar
tin bombers. each to launch six bombs
and IL DH-4's which will drop two
bombs each, ,aIl of the 163 pound
sype. The aircraft will deliver the at
Jack as the flight commanders choose
without any restrictions az to alti-
ude or speed.
To Drop 1873 Bombs
Itsis expected that by the time the
a. aircraft engaged in the test have
dropped their 1SS bombs the U-117
will have disappeared beneath the
surface of the water but should the
vessel still be afoat it will be made
the target of the guns of division
of destroyers on the following day,
along with the former German sub
marines. U-140, U-111 and UB-4S.
The second phase of the tests will
take place on June %. Officers of
both services consider this the most
important of all the experiments, as it
will involve the double problem of the
ability of aircraft to find any enemy
fleet somewhere in a wide area off
the coast and to sbomb the enemy
ships after locating them. On that
date the radio controlled battleship
iowa will be somewhere between tile
Virginia Capes and Cape Henlopen,
from so to 100 miles offshore. The
Iowa will be unanswered by radio
from the battkship Ohio, five or six
miles distant The flyers will have
only an approximate idea of the loca-
tion of the Iowa and will be required
to take off at a given signal, search
the wide area involved and, IL they
find the vessel, bomb it with dummy
bombs and get back to land safely

he allowed to maneuver the Iowa as
he pleases during the bombing, sfmu-
lating as far as possible the moves a
battleship might be expected to make
n war TO escape aerial attack. The
conditions involved are that the Iowa
shall continue to steam in the gener-
al direction of the shore and the at
lacking planes stay at an altitude of
at least 1900 feet. Eight o'clock in
the morning will be zero hour"
To Use Four DirigibIes
In the test against the Iowa all
available naval aircraft will be used,
including at least four dirigibles. Un-
der present plans the army will not
use any land planes in this test, but
the naval detachment will include
four Martin bombers assigned to the
marine corps. II is expected that
more than 100 aircraft will take part
in the search for an bombing of the
Iowa Dummy bombs ranging from
230 to 1000 pounds each will be used.
The army personnel involved will fly
seaplanes.
AS soon as contact is made by anvi
Of the scouting aircraft 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 general vicinity of
the test to go to the rescue of planes
forced down into the water.
Live bombs will not be used in the
experiment as the Navy wishes to
preserve the Iowa the only radio con-

data on the probable number of hits
