In Space War I, the U.N. Spacy made extensive use of Glamor's ES-11D Cat's Eye reconnaissance spaceplane. The ES-11D was designed for operation both in an atmosphere and in space the Cat's Eye makes use of two sets of engines for theatre–specific operation. In an atmosphere, the ES-11D makes use of two engines along either side of the dorsal-aft fuselage while in space it uses two wing-mounted reaction engines for propulsion and maneuvering.
A very small crew of one pilot in the aft seat and one operations officer in the front seat work in the cockpit of the ES-11D which features numerous displays for operating the large radome atop the craft.
Lieutenant Misa Hayase operated on board an ES-11D just before her capture and subsequent first contact with the Zentradi.
