Abstract: An umbilical cord for connecting the control systems within a control center to the operating systems of a projectile that is located within a launch tube and is to be launched therefrom, the umbilical cord comprising a cable having a plurality of conductors therein and having a control center end and a projectile end, a first connector terminated to the conductors at the control center and at a second connector terminated to the conductors at the projectile end, the second connector having insulation displacement contacts therein where the conductors are terminated and the second connector is captivatively pluggable into a recess in the side of the projectile through a port in the launch tube and upon the launching of the projectile, the connector remains with the projectile and the conductors remain with the launch tube, whereby the conductors are pulled free from the insulation displacement contacts.
