I have a question that I was hoping somebody here can help me with. The 6th Frigate Squadron, with the Rothesay class Frigates was based at Rosyth in the early 1980s. In 1985 it was joined by the 3rd Destroyer Squadron with four Type 42s. The 3rd Destroyer Squadron was relocated to Portsmouth in 1994 (announcement made in 1991). However what I can't work out is when the 6th Frigate Squadron relocated to Devonport? As a bonus it would be interesting to know why it was relocated to Devonport?
