SHUTTLECRAFT OPERATIONS The USS Enterprise is equipped with auxiliary shuttlecraft to support mission objectives. Standard complement of shuttlecraft includes ten standard personnel shuttles, ten cargo shuttles, and five special-purpose craft. Additional special-purpose shuttles can be provided to a starship as necessary. The Enterprise also carries twelve two-person shuttlepods for extravehicular and short-range use. Operating rules require that at least eleven shuttle vehicles be maintained at operational status at all times. Cruise Mode operating rules require one standard shuttlecraft and one shuttlepod to be at urgent standby at all times, available for launch at five minutesÕ notice. Four additional shuttlecraft are always available on immediate standby (thirty minutes to launch), and an additional six vehicles are maintained for launch with twelve hoursÕ notice. Red Alert Mode operating rules require two additional shuttles to be brought to urgent standby, and all nine remaining operational vehicles to be maintained at immediate standby. SHUTTLEBAYS The Galaxy class USS Enterprise has three major facilities intended for the support of auxiliary shuttlecraft operations from the ship. Shuttlebay exterior space doors are triple-layered compressible extruded duranium. Inner doors are composed of lightweight neofoam sheeting in an expanded tritanium framework. During active shuttlebay operations, atmospheric integrity is maintained by means of an annular forcefield, which permits both doors to remain open for vehicular ingress and egress without depressurizing the bay. Each shuttlebay has its own operations control booth, which is supervised by an on-duty Flight Deck Officer. Each Flight Deck Officer is responsible for operations within that particular shuttlebay, but must report to the main shuttlebay officer for launch and landing clearance. In turn, the main shuttlebay officer must seek clearance from the Operations Manager on the Main Bridge. Launch maneuvers and landing approach piloting is managed by a number of precision short-range tractor beam emitters located in each shuttlebay and on the shipÕs exterior, just outside each set of space doors. These tractor beams are computer controlled under the direction of the Flight Deck Officer, permitting the safe maneuvering of shuttle vehicles within the bays and in the 350-meter approach zone. Maintenance facilities include replacement parts sufficient for twelve months of normal starship operations. These normally include two complete replacement spaceframes, which can be used for refurbishment of severely damaged ships. Note that replicator usage can allow fabrication of nearly any critical missing parts, but large-scale replication is not considered energy-efficient except in emergency situations. However, in such situations, power usage is usually strictly limited, so it is unwise to depend upon the availability of replicated space parts. This is another reason that the ship must maintain a significant stock of spare parts in inventory at all times. Æ
