In 2002 it was announced that the first of the Royal Navy's new Type 45 destroyers would be assembled by BAE Systems at their Scotstoun Shipyard in Glasgow on the River Clyde. The initial intention was for the remainder to be assembled at the firm's large covered Devonshire Building Hall in Barrow-in-Furness (the former Vickers shipyard) using large blocks shipped down from Scotstoun. This was due to the significant size of the ships (8000 tons displacement compared to the 5500 ton displacement of the Type 42s that they would replace). Initially 12 Type 45s were planned but this was subsequently reduced to 8 then to 6. This new barge offloading quay was built at Scotstoun in the early part of 2004 to allow trans-shipment of blocks via barges to Barrow. A new access door to the block assembly hall can be seen in the background (photo taken on 14th, April 2004). However, following BAE Systems takeover of the Govan shipyard on the Clyde (from merchant shipbuilder Kvaerner Govan) and delays arising in the 'Astute' submarine building programme at Barrow it was decided to assemble all vessels on the Clyde. This facility was used to import blocks from Govan and the bow section from VT Shipbuilding at Portsmouth for Daring and to export blocks to Govan for subsequent ships.
