BAP Union - Peruvian Naval Training Vessel. BAP Unión (BEV-161) is the training ship of the Peruvian Navy built in 2012–2015 by Shipyard Marine Industrial Services of Peru. It is a four-masted, steel-hulled, class "A" barque. It has a total length (including bowsprit) of 115.50 m (378 ft 11 in); a beam of 13.50 m (44 ft 3 in); a draft of 6.50 m (21 ft 4 in); a mast height of 53.50 m (175 ft 6 in); a displacement of 3,200 tons; a speed of 12 kts (22 km/h) and a crew of 250 officers and trainees. The ship's name honors a Peruvian corvette that took part in the first stage of the 1879–1883 War of the Pacific as part of a naval squadron under the command of Miguel Grau, a hero of the Peruvian Navy. Like other similar ships, Unión has been conceived not only for training purposes, but also to be a sailing ambassador for its home country. Due to its features and dimensions, it has been considered (as of the date it was commissioned) the largest sail vessel in Latin America.
