investment and facilities construction." In October 2016, the Federal Government confirmed that ASC would be dissolved into three companies focused on different elements of current ASC works. One would be dedicated to the Air Warfare Destroyers, one to continued submarine sustainment and development and one to infrastructure development. Dissolution was expected to be complete by 2017. Under agreements struck with the South Australian Government, the newly formed infrastructure owner and manager, Australian Naval Infrastructure Pty Ltd (ANI), completed the acquisition of the Techport business in November 2017, enabling it to effectively consolidate ownership of the newly named Osborne Naval Shipyard precinct. Assets acquired included the Common User Facility and all shipyard infrastructure. On 27 July 2018, ASC delivered the second Air Warfare Destroyer, NUSHIP Brisbane (III)(DDG 41) to the Australian Defence Force. In December 2018, ASC Shipbuilding was structurally separated from ASC Pty Ltd, and acquired by BAE Systems Australia. In 2021, ASC Shipbuilding is officially re-named BAE Systems Australia Maritime. In 2020, ASC and CSIRO begin a two-year research collaboration looking to more efficiently repair precision submarine components by perfecting ‘cold spray’ additive manufacturing techniques. On 28 Feb 2020, ASC delivered the third and final Air Warfare Destroyer, NUSHIP Sydney (V)(DDG 42) to the ADF, marking the end of the shipbuilding for the Air Warfare Destroyer project SEA 4000. In August 2022 ASC announced the opening of a new science and technology hub at Lot Fourteen in Adelaide city centre, where research projects in fields such as robotics, artificial intelligence and machine learning would be undertaken. Products ASC rose to prominence in 1987 when it was contracted by the Australian Government to design and manufacture a fleet of six s for the Royal Australian Navy (RAN) in what was the largest defence contract ever signed in Australia. Although the submarine project was marred with difficulties throughout the 1990s, upon completion the Collins class were hailed as the most advanced diesel-electric submarines in the world. The difficulties continued, however, and the very expensive Collins-class submarines have been plagued with troubles and controversy ever since. ASC maintains the six Collins-class submarines for their operational lifespans under a A$3.5 billion contract with RAN. To date, no other navy has expressed interest in buying a Collins-class submarine. In 2005, the company was selected by the Australian Government, ahead of two other bidders, as the preferred shipbuilder for three new AEGIS-based Australian air warfare
