A bulk carrier or bulker is a merchant ship specially designed to transport unpackaged bulk cargo—such as grain, coal, ore, steel coils, and cement—in its cargo holds. Since the first specialized bulk carrier was built in 1852, economic forces have led to increased size and sophistication of these ships. Today's bulk carriers are specially designed to maximize capacity, safety, efficiency, and durability.
Today, bulk carriers make up 21 percent of the world's merchant fleets, and they range in size from single-hold mini-bulk carriers to mammoth ore ships able to carry 400,000 metric tons of deadweight (DWT). A number of specialized designs exist: some can unload their own cargo, some depend on port facilities for unloading, and some even package the cargo as it is loaded. Over half of all bulk carriers have Greek, Japanese, or Chinese owners, and more than a quarter are registered in Panama. South Korea is the largest single builder of bulk carriers, and 82 percent of these ships were built in Asia. (Full article...)

The SS America was an ocean liner built in 1940 for the United States Lines. She carried many names in the 54 years between her construction and her 1994 wrecking, as she served as the SSAmerica (carrying this name three different times during her career), the USS West Point, the SS Australis, the SS Italis, the SS Noga, the SS Alferdoss, and the SS American Star. She served most notably in passenger service as the SS America, and as the Greek-flagged SS Australis for Chandris. In 1941, she carried two Nazi spies from the Duquesne Spy Ring in her crew: Erwin Wilhelm Siegler and Franz Joseph Stigler. Both men were charged by the FBI with espionage and sentenced to 10 years and 16 years' imprisonment, respectively.
