I picked this up from Breviarium Romanum.
I am including only one of the photos. Be sure to visit them for a few more shots.
The Reverend Charles Johnson, Navy chaplain, celebrates the liturgy of the Feast of Saint John the Apostle aboard the aircraft carrier USS THEODORE ROOSEVELT (CVN 71).
Note the Gesu Bambino placed near the altar crucifix.
A statue of Our Lady is placed to the left of the altar for the celebration of Holy Mass. A US Navy Sailor serves as acolyte.
Please visit again for more details about the origin of Father’s Roman vestments in a festive floral style on a white ground.
Larger Navy ships such as aircraft carriers usually have a dedicated chapel space which must be maintained as a "neutral", or non-denominational, space when not in use by a particular religious group in order to better facilitate the beliefs of all.
The materials necessary for the celebration of the liturgy are stored away to be set up for each Holy Mass and then taken down again afterward.
I happily recall my visit to this carrier and meeting the fine Fr. Johnson.
Blessings upon him and thanks for his service and that of all good chaplains.
