Deck 4 houses the ship's V.I.P. staterooms. These compartments serve as quarters for visiting officers, ambassadors and their wives or husbands, and Federation government officials, among others. Each stateroom is composed of two areas. The room's entrance opens into the sleeping area, which has two beds. A door leads into the bathroom area. The other half of the stateroom is the work area. A library computer terminal and work desk are provided for guest use.
Also on Deck 4 are a conference room, where closed meetings may be held, and the ship's junior officers' quarters.
Water tanks and pump machinery ring the periphery of the deck, behind the outer bulkheads. Housed in this area also, at bow, port, and starboard positions, are the Eagle's upper phaser banks.
