SS Kielce was a Polish-operated cargo ship. She was a Type N3-S-A2 steamship, built in the USA in 1943 as SS Edgar Wakeman. In 1946, while laden with a cargo of munitions, she sank in the English Channel after colliding with the British or French steamer Lombardy. In 1967, an attempt to salvage her wreck inadvertently detonated some of her cargo, the resulting explosion was measured to be equivalent to a minor earthquake.
