This paper presents data describing the radial kinematics of the core of the complex object CTB 80, believed to be a supernova remnant. The radial velocity of the CTB 80 was found to extend between -130 and 95 km/sec (LSR), with the emission being brightest and most concentrated in filaments around -30 km/sec, and weaker at higher velocities. The character of the position-velocity diagrams was found to be consistent with models of expanding ellipsoidal shells. A comparison with these models indicated a short dimension for the core along the line of sight, and favors a momentum-driven expansion. This type of expansion is indicative of a neutron star excitation for the core of CTB 80, as opposed to a normal supernova shock.
