"A second state of the art UK aircraft carrier has delayed its departure to the largest Nato exercise in Europe since the cold war, a week after its sister ship cancelled its deployment due to a problem with its propeller."
"HMS Prince of Wales was set to depart from Portsmouth Harbour in the South of England on Sunday to sail to Exercise Steadfast Defender on Norway’s Arctic coast. However, it was forced to abandon its departure at the last minute.
The Ministry of Defence confirmed that the ship had been held back, but did not provide a reason for the decision."
