When the Battleship Missouri Memorial reopens Saturday after 12 weeks in a Pearl Harbor shipyard and an $18 million maintenance job, admission and guided tours will be free to Hawaii residents and U.S. military personnel on that day.

A complimentary “;Mighty Mo Pass,”; which the memorial has introduced as its new all-in-one ticket to experience the famous battleship, will be offered. The pass includes a single admission, plus a choice from one of the following tours:

» Mighty Mo Tour (35-minute guided tour)

» Guide2Go iPod Tour (audiovisual tour using the Apple “;iPod touch”; corresponding to shipboard signage)

» Acoustiguide Tour (audio-only tour also corresponding to signage)

» The option to tour the battleship at one's own pace along a variety of self-guided tour routes

In addition to tours running all day and enhanced food service on the pier, the memorial's annual Member and Volunteer Appreciation Ceremony will be held from 11 to 11:30 a.m. to acknowledge outstanding Friends of the Mighty Mo members, volunteers and other supporters.

For an additional $25, guests may upgrade to the Battle Stations Tour, a new 90-minute guided tour that focuses on this most important aspect of life at sea for every officer and battleship sailor aboard: battle readiness.

The tour will include many areas of the ship not accessible without a tour guide. This includes the inside of turret 1, an engine room, a plotting room and the “;Broadway”; (an internal corridor that extends two-thirds of the length of the ship). Children must be age 10 or older for this tour.
