YF-24 エボリューション


  • Manufacturer: Shinsei Industry

High-performance fighter which introduced various new technology. Design data was sent to each fleet by Shinsei Industries.

After canceling the development of the YF-24, Shinsei Industry continued the original development, focusing on ISC. Thus, the YF-24 Evolution which contained ISC in the airframe was completed (the prototype was called "Camel" because it had a large dorsal bulge for ISC storage).

The combination of the manned aircraft, VF-171, and the unmanned aircraft, QF-4000 series, properly established the system of duty, but the problem of the successor unit of the VF-171 surfaced in 2055. Initially, conversion to unmanned aircraft for the next main fighter was recommended, but at the end of 2057, Shinsei Industry submitted and demonstrated the YF-24 Evolution.

In simulated air combat where 3 prototypes participated, it defeated 12 VF-19s and VF-22s and 6 air-to-air specification QF-4000s. Then, in a simulated attack was devised by the space mobile fleet designating a large-sized space aircraft carrier as the central target, a single fighter folded in and made a direct hit to the bridge of the aircraft carrier with a simulated reaction warhead. As a result, the plan for deployment and adoption of the YF-24 Evolution was approved.

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.

The YF-24 design was provided to each emigrant fleet. Based on that, the Macross Frontier fleet modified, considering deployment in atmosphere and from an aircraft carrier important, improved ISC and more, producing and deploying as the VF-25. The VF-27 had the performance almost equivalent to a VF-25 with super parts equipment. Due to this, only the Beta-type and Gamma-type are known and any options other than the super fold booster and variations is unknown.

As of 2059, the VF-25 and VF-27 are the strongest VF, direct decedents of the YF-24 Evolution, which succeeded the YF-24, that Shinsei Industries completed; receiving ISC and Stage II thermonuclear turbine engines. However, it is considered that influence from the VF-19 went to the VF-25, and the VF-22 (YF-21) to the VF-27, and has become a compilation airframe VF development technology, respectively. The VF-25 and VF-27 are considered sister units with the basic design inherited from the YF-24, but performance tendencies differ. The VF-25 fuselage which considers maneuverability/aerodynamic both in concept and performance tendency which can be called the successor of the VF19, the VF-27 corresponds to a cyborg, puts consideration on firepower/output.

Design Features

Delta-wing design. ISC (Inertia Store Converter). Gravity/Inertia control system that was existed in the Protoculture age. Most models are for large-sized warships and smaller ones in the Queadluun-Rau Quimeliquola special inertia vector control system were confirmed. On Earth, development for the VF advanced based on it, where it enjoyed good popularity and was developed as ISC after the YF-24 plan. The ISC prototype of the YF-24 was a large-sized model and the system's gross weight reached as high as 18t that it could not be accommodated in the fuselage. It apparently stored up to 2G of acceleration for a 5-second interval as the limit. After the YF-24 plan was discontinued, a miniaturized and improved ISC progressed from Shinsei Industry's research and that model also withstood high G environment which could catch and shoot down a QF-4000 air-intercepting variant which was developed into the YF-24 Evolution. Furthermore, the VF-25's ISC/TO21 improved performance where it is assumed that acceleration of the cockpit at maximum can maintain 27.5G reduction for 120 seconds. Additionally, it is considered that the VF-27's ISC, the IVC/GC 01-gamma, has the same performance class. The inertia control mechanism for the VF ancestor, the Quimeliquola special inertia vector control system, was found in the Queadluun-Rau. Although the replica was equipped in the YF-21, inertia and acceleration were reduced by 10% or less, and there were cost and control problems where it was not adopted in the VF-22. The real model had to wait until the YF-24-series unit. EX-Gear. Stage II Thermonuclear engines. Linear actuators.
