Keeping Federation borders secure is the job of patrol craft like Mark Sandlin's LL-300. Often it's a matter of just having a visible presence. However, when that presence needs to be more than just visible, it's improortant to have a craft that's up to the job.
The LL-300 Patrol Craft was designed to patrol the edge of explored
space. Its broad wing shape provides ample lift in the thin atmospheres
of gas giants and terraforming planets. Equipped with two large drive
engines as well as two smaller intra-atmospheric engines, the LL-300 is
able to move quickly along the frontier to perform its mission duties.
The small onboard rover provides the crew with mobility when they must
venture onto a planet's surface.
