I present the Hero Ship of Castaways in her full Glory. Grace was originally a Franklin Type Starship called the U.S.S. Shenzou NCC-147, She was built in the Orbital Construction yards above Philadelphia and later fitted out over Cape Canaveral, Over the years she was upgraded with enhanced impulse engines which take the place of the cutout in the back of the saucer) Warp Field Stabilization Spikes, visible warp grilles in the inner surfaces of the warp nacelles and had the viewscreen window swapped for a more traditional monitor viewscreen. After the main cast of the show get their hands on her they have a makeshift deflector pod built with enhanced sensor packages and photonic torpedo launchers to assist them in their attempts to return home to the 21st century.
