Aeroshuttle Support Craft
The Aeroshuttle Support Craft is a runabout-sized spacecraft embedded in the saucer underside of Intrepid-class and later Pathfinder-class starships.
The craft was designed for atmospheric operations, and short-term missions as a support vessel, rather than as an independently operating small starship like the Danube-class on which it's based.
Specifications
In its basic configuration, the Aeroshuttle was 24.8 meters long with a 29.6 meter wingspan, and displaced 222.5 metric tons. It could accommodate six crewmen on a standard two week mission. It was capable of effective operations within planetary atmospheres ranging from class D to class J and was highly maneuverable in flight. Its sensors were optimised for planetary surveys, but could also be used for reconnaissance or covert operations. All shipboard systems were controlled and monitored by an M-15 Isolinear III processor.
Initially, the Aeroshuttle was mounted with two LF-9X4 Advanced Compact Linear Warp Drive Units and two FIB-3 Compact Subatomic Unified Energy Impulse Units, which gave it a cruising speed of Warp Factor 3 and a maximum velocity of Warp Factor 5. Advances in warp field technology and subsequent upgrades made over the service life of the Aeroshuttle have since increased those velocities.
Weapons and defense
An FSQ-2 Primary Force Field and Deflector Control System provided the main defensive systems, while offensive weaponry included four Type XII Phaser Arrays and two Mark 25 direct-fire Photon Microtorpedo tubes.
Interior
The inside of the Aeroshuttle was very similar to the Danube-class runabout on which it's based, including a Medical/Science lab with fold-away bio-bed, and bunks for up to nine crewmembers. It was equipped with a large 2-pad transporter, that was actually big enough to fit more than 6 people. The Aeroshuttle also had a large weapons locker, filled with Type-2 phasers and tricorders.
