LANCASTER Back – the Type 23 Frigate LANCASTER emerged in March 2012 from refit a sleeker, faster vessel following a year of extensive upkeep at Portsmouth Naval Base. The refit, part of a £17.9m contract with BAE Systems, has significantly upgraded the war fighting capability of the 20 year old Frigate, during which both propeller shafts replaced and received an extensive package of sea tube replacements, the main inlets that provide salt water to the main machinery cooling systems. Both rudders were removed for inspection, and a number of insert repairs to the hull were carried out.     A new coating of underwater paint that, along with the transom flap at the stern (an underwater spoiler) will cut fuel consumption by up to 15% providing a significant saving.        The ship has also has had upgrades to the SEA WOLF guided missile system, communications, command systems and the installation of an automatic 30mm gun which can be operated remotely.    The sister ship IRON DUKE is to follow.
