    Description and History

    In the mid 2050’s the New UN Spacy had established a system of duty in which manned variable fighters like the VF-171 Nightmare Plus would sortie along with unmanned aerospace craft like the QF-4000 Ghost series. This created a problem for the successor unit to the VF-171 when in 2055 there was a strong sentiment that aerospace forces of the future would deploy unmanned craft for the main fighter role. However, by the end of 2057, Shinsei Industry submitted and demonstrated the YF-24 Evolution. The original YF-24 was cancelled during development and Shinsei Industry decided to pursue original development of a variable fighter with a focus upon the Inertia Store Converter (ISC) technology. Thus, the YF-24 Evolution was built with an airframe that contained a new ISC for which the prototype was called the “Camel” due to the prominent dorsal bulge needed to accommodate the large system. The YF-24 Evolution became a high-performance fighter which introduced various new technologies in addition to the revolutionary ISC system.

    The technology of gravity/inertia control systems existed in the Protoculture age. Most models are for large-sized warships but there are some smaller units like the Quimeliquola special inertia vector control system built into the Queadluun-Rau of the Zentradi Army. On Earth, popularity of the technology ensured development proceeded for use in advanced variable fighters, eventually becoming the Inertia Store Converter (ISC) after the YF-24 plan. Although a replica Quimeliquola special inertia vector control system was equipped in the General Galaxy YF-21 variable fighter, inertia and acceleration were reduced by 10% or less. Due to cost and control problems, the system was not adopted in the VF-22 Sturmvogel II. Development continued, but the ISC prototype of the YF-24 was a large-sized model that was so massive (gross weight reached as high as 18 metric tons) it could not be accommodated in the fuselage. The system was also limited, able to store only up to 2G of acceleration for a 5-second interval. After the YF-24 plan was discontinued, the original Shinsei Industry research was progressed and an improved miniaturized ISC model was built that withstood a high G environment. The ISC would become incorporated into the new YF-24 Evolution after field testing proved an ISC-equipped craft could catch and shoot down the unmanned QF-4000 air-intercepting variant. Refinement continued in the VF-25 Messiah ISC/TO21 system to the point where acceleration on the cockpit could be reduced by 27.5G for up to 2 minutes (the VF-27 Lucifer ISC – the IVC/GC 01-gamma – is assumed to be the same performance class).

    The YF-24 Evolution equipped with the ISC performed remarkably. Three YF-24 Evolution fighters participated in simulated air combat tests in which they defeated 12 VF-19 Excaliburs and VF-22 Sturmvogels and 6 air-to-air specification QF-4000 Ghost fighters. The space mobile fleet then devised a simulated attack designating a large-sized space carrier as the primary target; a single YF-24 Evolution fighter de-folded into the combat zone and achieved a direct hit to the bridge of the space carrier with a simulated reaction warhead. The impressive results of the tests lead to approval for deployment and adoption of the YF-24 Evolution. Major Isamu Dyson of the Reserve service acted as the test pilot leader for the demonstration carried out at the New Edwards Cemetery and National Space Test Center.

    Once completed, Shinsei Industries provided the design data for the YF-24 Evolution to each emigrant fleet. The Macross Frontier fleet modified the YF-24 Evolution design into the VF-25 Messiah, a craft which improved the ISC and placed emphasis upon deployment in an atmosphere and from carriers. The Macross Galaxy fleet built the VF-27 Lucifer that boasted performance almost equivalent to a VF-25 Messiah equipped with Super parts. The VF-25 and VF-27 are considered sister units since they are both derived from the YF-24 Evolution. However, it has been stated the VF-25 Messiah design was influenced by the VF-19 Excalibur while the VF-27 Lucifer design was influenced by the VF-22 Sturmvogel II. Performance of the two new variable fighters differ; the VF-25 fuselage was built to consider maneuverability and aerodynamic performance while the VF-27 was built to accommodate a cyborg pilot with consideration for firepower and output.
