AIRPLANES ARE TO ATTACK
 BATTLESHIP IOWA TUESDAY

Washington, June 26.-The old battle snip Iowa. operated and unanswered by raolo impulses. will attempt to eIude navy and army airmen off the Atlantic coast Tuesday in effort to demon strate that aviation has not yet reached the point where the defense of the coast may be left entirely in the hands of the ne" branch of the national defense sys- tenn.
 The flyers will try to locate the Iowa While the vessel is still we'll off the coast and, having found her, to rain a shower or dummy bombs on her decks
 The Iowa experiment will be the sec ond of series of tests conducted jointly ny the navy and war departments to test the usefulness of aviation against naval vessels under various conditions and to proVlde both airmen and naval construc- tors with data otherwise unobtainabIe.
 In the first of the tests, conducted ;asr week, one former German submarine was sent to the bottom by aerial bombs in Is minutes and two others were sunk bv destroyer gunf1re.
 1 The Iowa and the battleship Ohio. con- 1 trol ship, will station more than one hun i dred miles off the coast between Hat | teras and Delaware Cape tomorrow. At 1 dawn Tuesday Capt F. L. Chadwick of the Ohio will break the seal of an-en- Velope containing secret instructions from the navy department, and at zero hour the Iowa will be headed in the genera direction of the mainland.
 For the purposes of the experiment
 the Iowa will represent an enemy fleet The Ohio, exercising complete contro over the Iowa by radio, will be abou five miles away.
