The Aegis Eclipse is a bomber designed to get in and strike before it’s even spotted. After extensive service with the UEE, this high-tech military stalwart is making its debut on the civilian market for 2947. The Eclipse is a strategic bomber developed in 2930 by Aegis Dynamics and utilized by the United Empire of Earth Navy (UEEN). It was designed to use advanced stealth technology to deliver a payload of torpedoes without triggering electronic early warning systems. Eclipse bombers have been used in raids against enemy capital ships and deployed against stationary ground installations. In 2947, as part of the Militia Mobilization Initiative, a civilian variant of the frame was made available to the general public.
