Hundreds of guests turned out to mark HMS St Albans’ return to frontline service following a £25million upgrade.

Families of crew members and dignitaries from the ship’s namesake town attended a rededication ceremony at Portsmouth Naval Base on Friday.

Lady Suzie Essenhigh who launched the Type 23 frigate in 2002 was also at the ceremony.

The Type 23 frigate spent 15 months in refit and now has a new main gun and upgraded Seawolf missile system.

The overhaul, carried out by BAE Systems in Portsmouth, also included a new command and control computer system, upgraded IT equipment, a new galley and improvements to crew accommodation.
