Atlantic: Day 1 of 2 of the sinking of the BISMARCK. Outdated British bi-plane Fairey Swordfish torpedo bombers from the HMS ARK ROYAL attack the great German battleship BISMARCK, hitting and jamming her rudder, leaving her running in circles. The BISMARCK will be polished off tomorrow and the HMS HOOD will be avenged.
A Fairey Swordfish "Stringbag"
Designed in the 1930s, the Fairey Swordfish bi-plane outlived several types intended to replace it and remained in front line service until V-E Day.
The Swordfish received the nickname "Stringbag" not because of its construction, but because of the seemingly endless variety of stores and equipment that the aircraft was cleared to carry. Crews likened the aircraft to a housewife's string shopping bag which was common at the time and, which due to its having no fixed shape, could adjust to hold any shape of packages. Like the shopping bag, the crews felt that the Swordfish could carry anything.
On May 26th the hunt for the Bismarck involved every available ship in the Royal Navy. "Force H" with HMS ARK ROYAL was coming up from Gibraltar and a large number of other warships had been detached from their Atlantic convoy escort duties and were making their way independently.
But it was a US Naval Ensign who made the first crucial sighting. The United States, still being neutral at this time, were not taking an 'active' part in hostilities, but had attached 17 airmen to the RAF, partly to assist with the familiarization of the new Catalina flying boats. Ensign Leonard B Smith was officially a "co-pilot and special observer." He had taken off from Northern Ireland at 0325 and was way out in the Atlantic at 1010 when he glimpsed the Bismarck through the clouds. He came round for a closer look. His report shows that he was not taking an entirely neutral, passive role in affairs.
Smith radioed in the sighting as the Bismarck unleashed anti-aircraft fire toward them, forcing the Catalina to take evasive measures. Other aircraft quickly joined the scene and the battle began that ended this day with the Bismark crippled.

USA: The Northrop P-61 Black Widow twin-boom, radar-equipped night fighter makes its first flight near Hawthorne, California.
A P-61A of 419th Night Fighter Squadron
The P-61 Black Widow (named for the spider) was the first operational US military aircraft designed specifically for night interception of opposing aircraft, and was the first aircraft specifically designed to use radar. It was all-metal, twin-engine, of a twin-boom design.
The P-61 had a crew of three: pilot, gunner, and radar operator. It was armed with four forward firing cannons mounted in the lower fuselage, and four machine guns.
Although not produced in the large numbers of its contemporaries (only 706 were built), the Black Widow was effectively operated as a night-fighter by United States Army Air Forces squadrons in the ETO, PTO, MTO and the CBI theaters during World War II.

The P-61 was equipped from day one with then super-secret radar which could locate enemy aircraft in the dark and which had the capability to see and distinguish other airplanes during periods of darkness or under conditions of poor visibility.
The radar operator's station was at the aft end of the gondola. The radar operator controlled the radar set and viewed its display scopes from the isolated rear compartment, which he entered by way of a small hatch with a built-in ladder on the underside of the aircraft. In addition to the radar systems themselves, the radar operator had intercom and radio controls, as well as the controls and sight for the remote turret.
In Airborne Intercept mode, the radar on the P-61 had a range of nearly five miles. It could also function as an airborne beacon / homing device, navigational aid, or in concert with interrogator-responder IFF units.
The P-61's radar operator located targets on his scope and steered the unit to track them, vectoring and steering the pilot to the radar target via oral instruction and correction. Once within range, the pilot used a smaller scope integrated into the main instrument panel to track and close on the target.
In terms of aerial combat, the P-61 Black Widow night fighters assigned to the PTO experienced a similar situation in 1945 as their European counterparts, where engagements with Japanese aircraft became sporadic. Several squadrons equipped with these night fighters claimed no kills during 1945.
On 15 Aug 45, however, the last two aerial victories by American pilots of the war are claimed to have been scored by P-61s of the 548th Night Fighter Squadron from the island of Ie Shima.
