That image is in the Australian War Memorial's collection.
c. 1944. The imprint of a Japanese kamikaze aircraft on the side of HMS Sussex. Incredibly, the aircraft hit the side of the HMS Sussex and fell into the ocean without damaging the ship.
(The image is in the public domain, at least in Australia).
HMS Sussex was a County class heavy cruiser of the Royal Navy. Because of treaty limitations, her armor was quite thin for a heavy cruiser, 1 to 4 inches thick in places, particularly the side (the "belt").
While its armor was weak against naval guns, aircraft are made to be as light as possible. If the plane "fell into the ocean" then it either lacked a bomb, or it was a dud. It may not have been a deliberate kamikaze, but an opportunistic attack, or simply pilot error. The biggest concern would be a fire from the fuel.
In his Service Histories of Royal Navy Warships in World War 2, Lt. Cmdr Geoffrey Mason, RN has for HMS Sussex on July 26th, 1945...
Under KAMIKAZE attacks during which two aircraft were destroyed.. Sustained slight structural damage above waterline by the wreckage of a Japanese aircraft. HM Minesweeper VESTAL was sunk and HMS AMEER was damaged.
