I can't claim the credits for this one, either. I know it may seem strange to put an entire Impound Yard under "Gear" but ... what else is it? It may be a bit larger than many other pieces of equipment, but as everyone knows - size matters not.

This station is a 2 level installation built around a single gravity-well projector. This projector is in constant operation, projecting a spherical gravity well outside of the station, to a distance of 1.5 km.

This gravity well is sustained to keep the ships in the yard in a stable orbit about the station. Gravity on the station is generated in the standard fashion with a vertical orientation.

This station is heavily armed and defended, given its secret nature, and the possiblility of attacks staged by the Rebellion. Given the large number of operational vessels in orbit about the station, this would make a prime target for the Rebellion.

The station has a compliment of 40 TIE fighters, and is usually supported by several small picket ships, as well as a larger frigate, or corvette.

Griam Impound Yard is supported by the Imperial Frigate Sentinel, a Nebulon-B frigate, as well as 2 Guardian class light cruisers. Orbiting the station for the time being, are:

1 Victory-class Star Destroyer (decommissioned, non-operational)
5 Carrack-class cruisers (2 operational)
11 Corellian corvettes (8 operational)
23 Rebel Transports (14 op)
17 Strike-class Cruisers (3 op)
8 Rebel Carrier Cruisers (5 op)
16 Lancer-class frigates (6 op)
2 Rebel Assault frigates (1 op)
12 Ghtroc light freighters (11 op)
16 modified YT-1300 freighters (12 op)
18 X-wing fighters (all op)
25 Y-wing fighters (all op)
13 A-wing fighters (all op)

Total 167 starships.

The base commander, Commander Serrin, likes to tinker with starship engineering, and maintenance, so in his spare time, he works on the ships in the yard, making them operational. He avoids doing this to the capital ships, though.
