USS McAnn, 1943 Cannon-class destroyer escort

The USS McAnn is a Cannon-class destroyer escort launched in 1943 at Federal Shipbuilding in Newark, New Jersey. Its grey steel hull carries a white numeral "4" near the bow, a white life ring with red markings, a multi-tiered superstructure, a tall mast with crossbars, and a gun barrel pointing forward. As Bauru, it shows "DE175" on the bow and a single cylindrical funnel.

Laid down at Federal Shipbuilding in Newark, New Jersey, on 17 May 1943 and commissioned on 11 October 1943, USS McAnn escorted convoys in the Atlantic and rescued the ten-man crew of a B-17 off Brazil in March 1944. Decommissioned at Natal on 15 August 1944, she was transferred to Brazil and commissioned as Bauru the next day. She served nearly 40 years, steaming 295,405 miles over 1,423 days at sea, and opened to the public as a museum ship in 1982.

The ship was named after Donald Roy McAnn, a sailor who died in combat during World War II. Visitors can see the cramped crew quarters and understand how sailors worked together and operated the vessel under difficult conditions.

The ship is moored at the Brazilian Navy Cultural Center in Rio de Janeiro, opened to visitors in 1982. Tours follow 14 spaces that recreate life aboard during World War II, including the kitchen and crew dormitory kept as they were in service. Access to the lower decks involves steep ladders and narrow passages.

The ship made voyages to different ports even after becoming a museum, including a notable visit to Salvador in 1985, making it a rare example of a functioning museum ship. These journeys show that despite its history, the vessel was not merely preserved statically but occasionally still moved under its own power.
