caption_attribution_description: English: SAMPSON multi-function AESA battle management radar antenna mounted aboard Royal Navy Type 45 air-defence destroyer HMS Dragon (D35) inbound to Portsmouth Naval Base, UK. This composite of two photographs taken less than one second apart shows the rotation of the back-to-back mounted, twin phased-array antennae incorporated into a single unit. The antenna has rotated approx 120° in approx 0.66 secs. Note that the unit is not actually a true globe; being wider across the face of the phrased-array scanner than between the faces.

context_page_description: The Type 45 destroyer, also known as the D or Daring class, is a class of six guided missile destroyers built for the United Kingdom's Royal Navy. The class is primarily designed for anti-aircraft and anti-missile warfare and is built around the PAAMS air-defence system utilizing the SAMPSON AESA and the S1850M long-range radars. The first three destroyers were assembled by BAE Systems Surface Fleet Solutions from partially prefabricated "blocks" built at different shipyards; the remaining three were built by BAE Systems Maritime – Naval Ships. The first ship in the Daring class, HMS Daring, was launched on 1 February 2006 and commissioned on 23 July 2009.
  The Type 45 destroyers were built to replace the Type 42 destroyers that had served during the Falklands War, with the last Type 42 being decommissioned in 2013. The National Audit Office reported that, during an "intensive attack", a single Type 45 could simultaneously track, engage and destroy more targets than five Type 42 destroyers operating together.
