The second season of the Australian drama Sea Patrol premiered on the Nine Network on 31 March 2008 and aired on Monday nights at 8:30 PM. The thirteen-episode season ended on 23 June 2008. The season introduced a new patrol boat, following the decommissioning of the original, Fremantle class boat in the final scenes of season one. The new HMAS Hammersley was of the Armidale class, reflecting the real-life changeover in the Australian fleet. The second season also featured the debut of a new main character, Able Seaman Rebecca "Bomber" Brown, as the boat's new cook. Though advertised by the Nine Network as Sea Patrol II: The Coup, episodes themselves bore no title other than Sea Patrol, and the ISAN number indicated that the episodes were merely episodes 14–26 of Sea Patrol. Continuing the format from the first season, episodes generally moved a season-long story arc along. As the Nine Network marketing indicated, this arc involved a coup on the Samaru Islands, a fictional island nation close to Australia. In many ways, the story was evocative of Operation ANODE, a peacekeeping mission to the Solomon Islands that has been called "the [operational] pinnacle for the Fremantle class" by the Australian Department of Defence.
