- Beginning: In 2545, the initial specification of the ship that would become Idris was established by the United Planets of Earth's (UPE) Weapons Development Bureau (WepDev). The frigate was part of a range of forward-thinking plans that attempt to reform Earth's military after the 第一次塔维因战争. These plans imagined a peacetime UPE with significantly expanded borders, both with territory annexed from the 塔维因 and the increased colonization of more distant planets. The specifics of what would be the Idris called for the development of an 85-meter, corvette-class spacecraft that could dock a pair of patrol fighters. These corvettes would be built more affordably and in greater numbers than current ships-of-the-line and would be rapidly deployed to help patrol the burgeoning 地球联合帝国 (UEE). The prime contractor role (covering both design and manufacturing) for the new ship was assigned to 圣盾动力 via no-bid contract with a number of component and support contracts going to smaller, now defunct concerns.
- Prototype: In 2549, the prototype of the ship began its space trials after three years of development pledged with typical bureaucratic confusion to outside observers. The ship was completely different from the initial specification of a corvette: a massive frigate-class spacecraft massing several times the original proposal, mounting an enormous railgun, and carrying a fully functional flight deck capable of supporting multiple classes of fighters and bombers. Contradictory to the observers, the move from the proposed corvette to the frigate was painless and seemingly natural for those involved, with the design specifications being revised multiple times as the reality of the post-war Empire became increasingly clear. Messer aligned planners quickly identified the project as important to establishing their own power base and they worked carefully with Aegis and other contractors, particularly Aim-Krug, responsible for the railgun installed on the first flight of ships, to expand the scope of design to define a model for the modern warship. Expansion from the original corvette to the frigate was a rare decision that was in the best interests of all persons involved. Highlighting the suggested importance of the project, the first ship was named after the recent victory at Idris IV, already being mythologized as a foundational element of the new Empire.[1]
