General Notes

When Tesla Browning took up the aegis of Project S from the defunct Seed Corp, he endeavored to repurpose Sekaino Megami’s superweapons against the Coalition. The VCD-2 would remain the centerpiece of the dread weapons system, but the destroyer lacked a viable targeting module.

The Project S team submitted several outboard targeting platform proposals. The idea of installing the Vercingetorix laser targeting system in a fighter craft emerged as a leading concept. Reasoning that a fighter’s high mobility and integrated weapons would maximize ease of deployment while affording the module built-in protection, a prototype was soon approved.

Browning Corp based the YFS-100 prototype on Maximus Darving’s HVRJ-2 airframe. For extra defense, they added carbyne laminar armor pioneered on the XCD-001-1. These design elements enabled the fighter to perform unaided atmospheric entry from outer space, greatly extending the VCD-2’s effective range. Kazoku War ace Zane Dellister contributed a pair of wing-mounted plasma cannons to give the fighter superior offensive capabilities.

Having produced a successful proof of concept in the YSF-100, a test type unit, the YFS-101, was soon green lighted. The test type resembled the prototype almost exactly, except the HVRJ-2’s pair of nose-mounted Vulcan cannons was restored. The caliber of the weapons was increased from 20mm to 30mm, granting extra punch against small-medium support vehicles and personnel.

The YFS-101 was never intended for deployment in the field. But when a shuttle carrying the One-Series XSeed prototype crashed in the Taklamakan Desert in CY 20, Zane himself piloted the testbed fighter in a desperate bid to rescue his wife Dorothy. When Dorothy proved dead at the Socs’ hands, Zane swore revenge, culminating in a suicide strike using the YFS-101’s nuclear self-detonator.

  1. It looks a bit like the Firefox aircraft from the movie of the same name.

    1. Thanks. I've always had an appreciation for that film.
