DARING-Class Destroyer HMS DEFENDER sailed up the Thames this week, arriving at her mooring at Greenwich early on Wednesday morning.
She made her way up the river under the cover of darkness, passing through the Thames Barrier - the first Type-45 vessel to do so - at about 3am.
The visit by the 500ft long warship is to coincide with events to mark the centenary of the Battle of Gallipoli.
Tickets for public tours taking place on board this weekend were soon snapped up after being advertised in a local newspaper and on social media.
Defender will be joined in London later today (Friday) by the minehunter HMS Middleton which is due at HMS President in Wapping for the weekend.
You can see HMS Defender making her way down the river on Tuesday morning - she is expected to set off around 0900.
