Two of the Japanese carrier Hiryu's Type 97 shipboard attack aircraft (far right) approach the drop point, during the torpedo attack on USS Yorktown (CV-5) in the mid-afternoon of 4 June 1942. The lower plane's Type 91 torpedo is clearly visible below the fuselage. Note heavy anti-aircraft fire, with shell fragments splashing in the water below the bursts.
