The FF-X5 Prototype Core Fighter is an aircraft that is featured in the design series MSV-R.

Technology & Combat Characteristics

A prototype fighter developed by Hervic, based on the data obtained from the Core Blocks and Core Fighters of the previous individual prototypes as a common cockpit module for the RX series. Compared to the later FF-X7, the wing surface shape of the main wings is different, and it is not equipped with any armament.


Two Prototype Core Fighters were produced, and underwent a series of testing as the Core Block of the RX-78-1 Prototype Gundam. These include launching from the mobile suit, transformation into fighter form, mobility test in fighter form, and, most challenging of all, mid-air docking.

At an unspecified date, one unit attempted the mid-air docking test above a desert in South America with a Gunperry. It was able to successfully dock with the B-part, but failed to dock with the A-part before the altitude limit was reached, forcing it to separate with the B-part and transform back into fighter form. Both parts survived undamaged due to parachutes attached to them, and were recovered.

Five days later, the test was repeated, and the Prototype Core Fighter was able to successfully dock just before the limit was reached. 17 subsequent tests at various altitudes were conducted, and it was determined that aerial docking could only be conducted by highly experienced pilots.

After various tests, it was determined that the Prototype Core Fighter had insufficient engine power, necessitating a change of engine to ensure a safe ejection. The prototype Unit 1 was later modified into the FF-X7, featuring a new engine, weaponry, and different wing shapes. It would continue to serve as the Core Block of the Prototype Gundam.
