Celebrity Silhouette is built to the same design as her preceding three Solstice-class sister ships (Solstice, Equinox, and Eclipse),[7] but measures approximately 400 tons larger and six feet longer.

In May 2007, Celebrity Cruises announced it had ordered its fourth Solstice-class ship with German shipbuilder Meyer Werft for a tentative fall 2011 debut.

[4] She sailed to Hamburg for her naming ceremony on 21 July 2011,[4] where Michelle Morgan, president and CEO of Signature Travel Network, christened the vessel.

[4][5] She moved in fall 2011 to the Cape Liberty Cruise Port in Bayonne, New Jersey, where she operated 12-night Caribbean itineraries to complete her inaugural year.

[13][14] In November 2023, an onboard youth counselor admitted to the FBI to that he sexually abused multiple children aboard the ship.
