Niicee was a group of 6 Class-B containers used by the Rebel Alliance. One of the containers, Niicee 5, contained a Missile Boat prototype called Sealion and was planned to be transported to an undisclosed location to dissect it and learn how to duplicate it. The Rebels didn't have the chance to as Imperial forces led by Darth Vader would launch an recovery operation on the container that housed the Sealion, the rest that contained warheads were destroyed.
