U.S.A.: President Franklin D. Roosevelt establishes a National defence Research Committee to correlate and support scientific research on the mechanisms and devices of war. Among its members are officers of the War and Navy Departments appointed by the respective Secretaries of War and the Navy. Although research on the problems of flight are specifically excluded from its functions, this organization makes substantial contributions in various fields of importance to aviation, including airborne radar. 

President Roosevelt invokes the Espionage Act of 1917 to exercise control over shipping movements off the U.S. coast and in the vicinity of the Panama Canal.

A confidential meeting is held between members of the British and Australian governments and US Secretary of State Hull regarding their concerns about the Japanese build up. They request either economic measures or movement of some naval vessels to the area of Malaysia or the Philippines. Cordell Hull does not agree to any of these proposals. They would constitute a more active foreign policy than the Administration believes the American public is prepared to tolerate. (Marc Small)

Battleship USS Iowa laid down.

ATLANTIC OCEAN: At 0338, the unescorted Lenda was missed by U-47 with one torpedo. Then the U-boat began shelling the ship for the next 20 minutes until she caught fire. The crew then abandoned ship in the starboard lifeboat, because the shelling had damaged the port lifeboat. The boat stayed near the ship for a while in the hope to find the first mate that was missing. The ship was on fire aft and amidships and the sea entered through holes at the waterline on the port side, so the U-boat left her in this sinking condition. But at dawn, some of the crew reboarded the vessel and they found the first mate dead on the port side of the upper bridge. A workboat was lowered and eight of the men transferred to it, whereupon both boats left and headed for the south of Ireland, just before two explosions were heard, followed by a tall column of fire which appeared to come from the engine room. Lenda remained afloat for a while on her cargo, but finally sank in 50°N/13°24W, about 160 miles southwest of Fastnet, Ireland. The survivors were picked up in the afternoon by destroyers HMS Hurricane and Havelock and taken to Plymouth on 30 June, respectively 2 July.

At 1705, the unescorted Leticia was attacked by U-47 with gunfire about 135 miles west of Ireland. The U-boat was only spotted when it opened fire from a distance of about 300 meters from the stern. The shelling killed the second engineer, seriously wounded the second mate and slightly wounded the master and a British donkeyman. Prien ceased fire to allow the crew to abandon ship in both lifeboats, but one British sailor fell overboard and drowned. After the lifeboats sailed away the U-boat again shelled the ship until she sank at 18.11 hours. Three men, which had remained on board, had to jump overboard and were picked up by U-47. They got dry clothing and schnaps and were brought to the lifeboats. First aid materials, some sausages and wine were given to the survivors before the U-boat left the area. The same day, the survivors were picked up by HMS Hurricane and landed at Plymouth two days later.
