SIGNIFICANT TEST TOMORROW.
One of the most significant ofsthese
tests will come tomorrow, when army
and navy planes will be set to the
task of locating and bombing the for
mer United States battleship Iowa,
which. maneuvering at full speed un-
der radio control, will make q simu-
lated attack upon the Virginia coast.
This test will not be for the pur4
pose OF showing the effect of live
bombs upon modern armor plate
This phase of the problem will be
faced by aviators next month, when
a number of the larger former Ger
man ships will be bombed.
The Iowa tests will demonstrate tn.
ability OF aviators TO locate and
strike, with dummy bombs, q moving
and maneuverable target far at sea
Do"n HrrESI NESIS LATEh-
The effect of bombs on heavy armor
