Yes the works to prepare the dockyard took 3 years. Not just preparing the berth but dredging the channel as well. The dredging brought up a lot of unexpected material; unexploded German bombs, an RN torpedo, etc etc.
a snowman on the ship , very intelligent design , with that tower , russian army radar could detect the ship 3000 miles away, british designs are tragic and funny.
@Mustafa Umut Sarac What you say is funny and misinformed. The Type 45 destroyers have very significant radar signature reduction which is why they are designed the way they are. The tower you mention is the ship's own highly sophisticated radar system.
