Occupying the forward end of Deck 20, reaching from port to starboard, is the Eagle's matter/antimatter containment system. This specialized unit regulates the amount of fuel that flows into the intermix chambers. Storage bottles affixed to the outside of the containment unit hold the matter and antimatter which powers the vessel; this fuel is kept in a plasma state and is insulated from the interior walls of the bottles by intense magnetic fields. Blow-away panels in the outer hull of the ship allow the antimatter storage bottles to be independently ejected into space should an emergency situation arise (such as magnetic field failure).
Just aft of the containment machinery, on the vessel centerline, is the tractor beam unit housing. Normally stowed retracted, the telescoping beam projector features a swiveling head which is shaped to form a flush seal with the outer hull.
The ship's botanical garden, along with an adjoining botanical laboratory, serves both the scientific and hobbyist requirements of shipboard personnel. A wide variety of plant life, in all shapes and colors, makes this area a favorite of off-duty personnel. Bench seating allows restful viewing of the garden, and a small snack bar is useful for games and conversation. A fresh-water stream and pond is stocked with many species of tropical fish, and features its own water supply and recirculation equipment.
A spacious messroom is connected to the garden by two corridors. This dining area has an adjoining specialty kitchen where crew members may prepare foods without the use of food processor machinery, if they wish.
The Eagle's pool and sundeck fills out the aft third of Deck 20. The regulation pool reaches a depth of twelve feet at one end, and gradually rises to three feet in the shallows. A diving board is available for personnel use.
Mounted onto the walls surrounding the pool and sundeck are a series of wraparound viewscreens. These may be programmed to display a wide variety of three-dimensional beach and island scenes which creates a convincing illusion of Terran shore leave.
