The VF-31 (Universal Strike Fighter) is a Variable Fighter developed by Misriah Armories for the UNSCDF. It is in service with the UCR Armed Forces and Cineris Air Service.

Technology and Combat characteristicsEdit

Developed as a high end fighter by Misriah, it was dropped from the competition. Instead of scrapping all the concepts they had made Misriah instead recycled their test plane into a low cost variable fighter that could be cheap, effective and adaptable to most situations. The VF-31 is able to utilize most weapons that are found on other variable fighters, decreasing the need for different inventories. The VF-31 was powered by a pair of conventional thermonuclear engines rather than the stronger Naoto turbines. These engines were changed to the F450-200 engine, a derivative of the types used by the VF-29D.


On October 15, 2576 five YF-31s were tested within the former United States. They partook in simulated combat against restored or captured UCR Variable Fighters. The UNSC approved for continued development and eventually production of the VF-31. In early 2579 Misriah announced that they would be selling the 31 to any country interested in purchasing them. The UCR and Cineris both have purchased 31's.

A few VF-31's were used in Blue Flag mock battles with Cineris and UCR.

By 2582 the VF-31 reached over 6,000 delivered in the UEG.
