Atlantico (ex-UK Ocean)

HMS Ocean was a landing platform helicopter, formerly the UK's helicopter carrier and the fleet flagship of the Royal Navy. She was designed to support amphibious landing operations and to support the staff of Commander UK Amphibious Force and Commander UK Landing Force. She was constructed in the mid-1990s by Kvaerner Govan on the River Clyde and fitted out by VSEL at Barrow-in-Furness prior to trials and subsequent acceptance in service. Ocean was commissioned in September 1998 at her home port HMNB Devonport, Plymouth. In December 2017, the Brazilian Navy confirmed the purchase of the ship for £84.6 million. Following her decommissioning from Royal Navy service on 27 March 2018, she arrived in Rio de Janeiro on 25 August 2018, rechristened as the Atlântico and now serves as the flagship of the Brazilian Navy.

Designed in the early 1990s to address a critical gap in the Royal Navy's rapid-reaction amphibious capabilities, the vessel was constructed using commercial shipbuilding standards to significantly reduce procurement costs. During its British service, the ship served as a highly versatile platform, notably deploying Apache attack helicopters during the 2011 military intervention in Libya and supporting allied operations during the 2003 invasion of Iraq. Following its decommissioning by the Royal Navy in 2018, the vessel was sold to Brazil, where it was commissioned as the fleet's flagship. Today, it continues to serve as a vital asset for South American maritime security, designated as a multipurpose aircraft carrier capable of conducting command, control, and humanitarian missions.
