PLANS FOR JOINT
 OPERATIONS GIVEN
Elaborate Programme of Mimic Warfare Revealed by h.
 StruCtions Made Public
By Associated Press

New York, June 3.--Instructions to the fleet for the joint army and navy battle operations against surrendered German war craft and the obsolete battleship Iowa, off the Virginia capes from June 2L, to July 20, made public today, reveal an elaborate programme of mimic warfare.
 The enemy vessels to be destroyed by aircraft and gun fire include the U-1l7, U-140, U-4S, U-11, the destroyer G-102, S-132, V-43, the cruiser Frank furt and the battleship Ostfriesland.
 The former German craft will be brought to the firing point and aE- chored in position about 90 miles east of Cape Charles light vessel in not less than 50 fathoms of water. If more than one ship of a type to be bombed lis in the same vicinity, the submarine or destroyer to be bombed will be de- signated by red, white and blue circles | on the deck to avoid confusion. 1 Opening operations against the u-111 will be launcned by seven divisions of naval planes using 163-pound bombs. If this submarine has not been sunk by i naval aircraft, army planes will at tack with 250-pound bombs. Should the
 
 marines, a division of destroyers will attack by gun fire.
 Attacks by all aircraft will be made at an altitude of not less than 1000 feet and maximum speed. The sub marines will be anchored in column formation, 300 yards apart. The de- stroyers, one for each submarine, will then approach from a distance of B. 900 yards and attack, opening fire at de f1a. stroyer will be allowed ten rounds per gun.
 At the conclusion any submarine afloat will be sunk with depth charges by a wrecking party from the North Dakota.
 Radio Control.
 The search for the Iowa will bring into play all the ingenuity of aircraft and destroyers. She will move under radio control of the Ohio and at the zero hour will be at some point be- tween the latitude of Cape Hatteras and Cape Henlopen, 50 to 100 miles off shore, steaming at maximum speed in a general direction off the shore. The Ohio, while controlling the Iowa, wii- be five miles astern of her
 Army and navy seaplanes and four army dirigibles will form scouting line between Cape Hatteras and Cape
 
 100 miles off shore or until contact is made with the Iowa. As soon as con tact is made, aircraft will flash the news giving position, course and speed of the enemy" Planes on the scout ing line will then assemble by divisions and proceed 10 the attack in order of light bombardment squadrons, then heavy bombardment squadrons and sea- planes.
 Should any of the former German destroyers remain afloat after the at tack by aircraft and destroyers di- vision of battleships will finish them at range of 10000 yards, using sec ondary batteries only.
 The air attack on the Frankfurt will be with navy 250-pound bombs and army 300-pound bombs. The board or observers will make an examination of the ship after each attack. A sec ond series cf attacks will be made with 520-pound bbmbs
 The experiments with the battleship series of aerial attacks, each plane dropping two bombs in, each attack. On the second day 1,000-pound bombs will be used and if a hit is scored, 2,OOO-pound bombs will be dropped.
 If the bomb attack fails to sink the Ostfriesland, the dreadnaught Penn sylvania will open fire with her main battery at 1S.000 yards Full or har salvos may be used to obtain the nec- essary number of hits with the least expenditure of ammunition. If the Ostfriesland is still afloat after the Pennsylvania has used her heavy ar tillery, she will be sunk by depth charges.
