She is fitted with two General Electric LM2500+ gas turbines and is fitted with two Rolls-Royce Mermaid azimuthing electric pod propulsion units. These pods proved unreliable early in the ship's career but now with upgrades and operational experience they are now very reliable. She also has three bow thrusters.

Layout

At the time of her launch she along with her sisters was one of the first to have a three storey Grand Foyer and one of the earliest sea view glass elevators on a cruise ship.

As per the practice with the other ships of her class she included a remembrance in one of her restaurants to a historic early liner in the form of several panels and a bronze statue from the Compagnie Générale Transatlantique ship SS Normandie. The statue which was named La Normandie had been purchased by Celebrity Cruises from the Miami Beach based Fontainebleau Miami Beach Hotel.

In 2012, Celebrity Summit she was upgraded at a cost of US$16 million to incorporate features from the Solstice class ships. This resulted in new color schemes, new specialty restaurants replacing the Champagne and Conservancy bars, relocation of the Martini Bar. the ship has also had over modification over her service life, including installing of a convention center and 17 new cabins in place of a small theater and on Deck 11 the installation of 43 new cabins. In total these increased here double occupancy to 2,158 passengers and her gross tonnage 90,940 GT.

Celebrity Summit spent approximately three weeks in dry dock followed by time in the shipyard in March 2019 having all of her existing cabins and suites refurbished as well as the addition of 30 new cabins which will bring her total capacity to 2,218 (double occupancy).

Operation

Based in Bayonne, New Jersey or San Juan, she cruises to destinations in the Caribbean.

On 3 April 2010, passenger Bob Cricius fell overboard and swam for 19 hours to Cayo Lobos, 3 miles off the coast of Fajardo, Puerto Rico.

In March 2017, Summit had an unscheduled dry dock because of a propulsion issue. One cruise was canceled and another one was shortened
