ECHO Launched the 70^th Anniversary Event – the Survey Ship ECHO helped launch the impending Battle of Atlantic events in Liverpool with veterans joining the ship as the vessel sailed into port.     Fresh from gathering data in the Irish Sea, the ECHO sailed up the Mersey into the heart of Liverpool which will be the focal point of five days of events in May 2013.    The launch coincided with six NATO warships departing the Mersey after a short break – these were the Mine Countermeasures Group, currently being lead by the Polish ORP which had been taking a break between training off Zeebrugge and joining the latest Joint Warrior Exercise off Western Scotland that begins shortly.
