The text between the asterixes would be the write up on the aircraft. The text afterward is information on the development of the aircraft. The text in between the dashes is weapon information that I threw out on missile systems that I created to suit the concept.
**** High Speed Aircraft Interceptor/Anti- Cruise Missile Platform. With its cryogenic fuel, axial flow turbojet it is the fastest survice jet to date. Its systems are fully shielded against EMP effects for use with the avalanche tactical nuke. It is an incredible display of modern technology. ****
Following the dismal field performance of the tomahawk missile defence system, and North Korea's nuclear proliferation and cruise missile program, the pentagon saw a need for an intelligent, high speed missile defense system. The initiative called to utilize an UAV type craft, but pending the maturation of that technology, an interim solution was needed.
Lockheed was commissioned to resolve this problem. The YF-25 was developed to fill this urgent need for a very high speed interceptor. Sharing some 28% of its components with the F/A-22, the design is indicative of a lower cost solution.
Lockheed began by testing the F/A-22 platform with the much larger, more powerful F-132 high by-pass, axial flow turbojet. This 43,000 lbs thrust class engine is capable of pushing the YF-25 beyond mach 3.5 at an altitude of 80,000 feet. During windtunnel testing it was found that the F/A-22's wing geometry produced too much wave drag at speeds above mach 2.5. In order to combat this Lockheed tried thinning the airfoil profile. This resulted in unacceptible levels of elastic wing deformation, so a canard delta wing configuration was adopted. This allowed the wings to be thick and sturdy while remaining well inside of the conical shockwave eminating from the aircraft's nose.
The type has more post mach 3 endurance than it's closest counter-part, the MiG-25 Foxbat, and does not suffer from the same engine heat problems thanks to its cryogenic fuel system and use of thermal plastics.
While this aircraft has amazing high speed performance, the delta wing lends it low lift and high drag characteristics at subsonic speeds, decreasing it's cruise range. Although it is equipped with 2 dimensional thrust vectoring and does not have a maneouverability deficiency at low speeds like most delta wing configurations, it suffers from stability problems at high angles of attack. This makes it unsuitable to serve in an air superiority fighter role.
While an ultimately successful interceptor design, the project was abandoned after the North Korean missile crisis diminished. A number of prototypes and test models were built that were procured by X-Corp whom later reopenned the project.
The YF-25 is typically armed with the large, long range, tactical nuclear tipped Avalanche missile system on an underbelly pylon for anti-missile/anti aircraft missions. This allows near misses to splash small, airborne targets with EMP and overpressure effects. It is also capable of carrying an array of other weapon systems in its internal bays, such as the stingray medium range, radar guided missile. It can not be armed with both at once, however, as the Avalanche missile blocks the bay door when mounted. Within an internal gun bay, the YF-25 is armed with a 20mm M61 vulcan cannon.
