Type-9A shuttlecraft

The Type-9A shuttlecraft was a large Federation cargo shuttle in service during the 24th century. The main production base for these shuttles was Starfleet Plant #24, Utopia Planitia Fleet Yards, Mars. They were routinely carried aboard starships, and also worked at Starfleet shipbuilding yards, transporting components to orbit from a planet surface. 

Specifications
In its standard configuration, the Type-9A cargo shuttle could accomodate two flight crew and one cargo specialist. It was equipped with two 2,150 millicochrane warp engines which gave it a maximum speed of warp 2 for 36 hours, and twelve DeFI 2142 microfusion RCS thrusters. It had a mass of 4.5 metric tonnes when empty, and a maximum payload of 6.6 metric tonnes.

Uprated version
In its uprated specification, the Type-9A had two 2,175 millicochrane warp engines increasing its speed to warp 2.2, but for a reduced 32 hours. Its payload was also increased to 8.9 metric tonnes.

Special operations
For special operations, two type V phaser emitters could be mounted, one each on the upper forward tip of the warp nacelles.
