Heavy black smoke from her stack and white smoke from her bow indicate that the view was taken just after those areas were hit by bombs. The destroyer in the lower left appears to be USS Phelps (DD-360).
context_page_description: USS Lexington (CV-2), nicknamed "Lady Lex", was an early aircraft carrier built for the United States Navy. She was the lead ship of the Lexington class; her only sister ship, Saratoga, was commissioned a month earlier. Originally designed as a battlecruiser, she was converted into one of the Navy's first aircraft carriers during construction to comply with the terms of the Washington Naval Treaty of 1922, which essentially terminated all new battleship and battlecruiser construction. The ship entered service in 1928 and was assigned to the Pacific Fleet for her entire career. Lexington and Saratoga were used to develop and refine carrier tactics in a series of annual exercises before World War II. On more than one occasion these included successfully staged surprise attacks on Pearl Harbor, Hawaii. The ship's turbo-electric propulsion system allowed her to supplement the electrical supply of Tacoma, Washington, during a drought in late 1929 to early 1930. She also delivered medical personnel and relief supplies to Managua, Nicaragua, after an earthquake in 1931.
  Lexington was at sea when the Pacific War began on 7 December 1941, ferrying fighter aircraft to Midway Island.
context_section_description: Both Task Forces needed to refuel, but TF 17 finished first and Fletcher took Yorktown and her consorts northward toward the Solomon Islands on 2 May. TF 11 was ordered to rendezvous with TF 17 and Task Force 44, the former ANZAC Squadron, further west into the Coral Sea on 4 May. The Japanese opened Operation Mo by occupying Tulagi on 3 May. Alerted by Allied reconnaissance aircraft, Fletcher decided to attack Japanese shipping there the following day. The air strike on Tulagi confirmed that at least one American carrier was in the vicinity, but the Japanese had no idea of its location. They launched a number of reconnaissance aircraft the following day to search for the Americans, but without result. One H6K flying boat spotted Yorktown, but was shot down by one of Yorktown's Wildcat fighters before she could radio a report. US Army Air Forces (USAAF) aircraft spotted Shōhō southwest of Bougainville Island on 5 May, but she was too far north to be attacked by the American carriers, which were refueling. That day, Fletcher received Ultra intelligence that placed the three Japanese carriers known to be involved in Operation Mo near Bougainville Island, and predicted 10 May as the date of the invasion. It also predicted airstrikes by the Japanese carriers in support of the invasion several days before 10 May. Based on this information, Fletcher planned to complete refueling on 6 May and to move closer to the eastern tip of New Guinea to be in a position to locate and attack Japanese forces on 7 May.
  Another H6K spotted the Americans during the morning of 6 May and successfully shadowed them until 1400. The Japanese, however, were unwilling or unable to launch air strikes in poor weather or without updated spot reports. Both sides believed they knew where the other force was, and expected to fight the next day. The Japanese were the first to spot their opponents when one aircraft found the oiler Neosho escorted by the destroyer Sims at 0722, south of the strike force. They were misidentified as a carrier and a cruiser so the fleet carriers Shōkaku and Zuikaku launched an airstrike 40 minutes later that sank Sims and damaged Neosho badly enough that she had to be scuttled a few days later. The American carriers were west of the Japanese carriers, not south, and they were spotted by other Japanese aircraft shortly after the carriers had launched their attack on Neosho and Sims.
  American reconnaissance aircraft reported two Japanese heavy cruisers northeast of Misima Island in the Louisiade Archipelago off the eastern tip of New Guinea at 07:35 and two carriers at 08:15. An hour later Fletcher ordered an airstrike launched, believing that the two carriers reported were Shōkaku and Zuikaku. Lexington and Yorktown launched a total of 53 Dauntlesses and 22 Devastators escorted by 18 Wildcats. The 08:15 report turned out to be miscoded, as the pilot had intended to report two heavy cruisers, but USAAF aircraft had spotted Shōhō, her escorts and the invasion convoy in the meantime. As the latest spot report plotted only 30 nautical miles (56 km; 35 mi) away from the 08:15 report, the aircraft en route were diverted to this new target.
  Shōhō and the rest of the main force were spotted by aircraft from Lexington at 10:40. At this time, Shōhō's patrolling fighters consisted of two Mitsubishi A5M "Claudes" and one Mitsubishi A6M Zero. The dive bombers of VS-2 began their attack at 1110 as the three Japanese fighters attacked the Dauntlesses in their dive. None of the dive bombers hit Shōhō, which was maneuvering to avoid their bombs; one Zero shot down a Dauntless after it had pulled out of its dive; several other Dauntlesses were also damaged. The carrier launched three more Zeros immediately after this attack to reinforce its defences. The Dauntlesses of VB-2 began their attack at 11:18 and they hit Shōhō twice with 1,000-pound (450 kg) bombs. These penetrated the ship's flight deck and burst inside her hangars, setting the fueled and armed aircraft there on fire. A minute later the Devastators of VT-2 began dropping their torpedoes
