Pogašček Class and T8-Shuttlecraft.
The first Pogašček Class was assigned as medium-range destroyer (25547 A.L.), but turned out to be a better escorter. With its Warp 9,884 capability, it is perfect for both purposes, and stayed in service for almost 450 years.
At the front you see the main bridge, the two open circles behind the bridge are turbolifts. At the top of the image beneath the Shuttle, you can see the Cargo Bay. You can also see the Mess Hall lower. More at the end of the ship you see the Warp Core and the Matter Transmitter, and the ship's big Warp Nacelles.
The shuttle is something I drew for fun.
