The ship is being assembled on the River Clyde in Glasgow.[4] The first steel was cut for Glasgow in July 2017 with the ship expected to be delivered in 2024 and operational in about 2026.[5][6][7] However, those dates have since moved to the right. In January 2018, work started on the second hull section.[8]
In January 2020, the Royal Navy announced that the ship was more than halfway through construction.[9] In July 2020, the Royal Navy announced that work on the final section of Glasgow has started.[10]
On 18 April 2021, the fore section of the ship moved out from its building shed on the Clyde, and on 1 May 2021 was joined with its aft section for the first time.[11][12] She was then launched on 25 November 2022 in preparation for tow to the BAE Scotstoun shipyard for her fitting out.[13] Commissioning was anticipated by late 2026 to be followed by a work-up period prior to reaching initial operating capability.[14] In October 2022, the Secretary of State for Defence, Ben Wallace, stated that the initial operating capability (IOC) for the ship had slipped from 2027 to 2028.[15]
In May 2023, UK Defence Journal reported that around 60 of the ship's cables had been cut, sabotage possibly related to a pay dispute.[16]
