Hi Steve, Nice to see you are still about. Busy with the aircraft? Was off when Nitze was in POrtsmouth, had too much to do at home unfortunately. Always tomorrow.

Hi Chris......great shots mate, I missed her departure unfortunately :-(

Portsmouth (HMS Dolphin, Gosport in fact) lost her based Submarine's when the last of the Upholder Class were decommissioned.
All T Class Submarines are based in Devonport (Plymouth) whereas the S Class are based at Faslane in Scotland. All future SSN's (the new Astute Class) will be based at Faslane.

Hello Marc, nice to hear from you again.
What I gleaned about Trafalgar was that it was supposed to go to Davenport for minor repairs to her "tiles" but Davenport are holding a Navy Day/Week there so Trafalgar was directed to Portsmouth until cleared for Davenport.

Impressive view of a lethal weapon.
I believe she and her class are not regular callers at Portsmouth as their base is at Faslane.
