Along with the development of the experimental Stealth Jump Jet, Jundroo Aerospace has been developed the prototype variant of their Delta Wing Fighter, with next-gen looking, multirole capabilities, and equipped with stealth technology.

The Stealth-Pen Proto, or the Pigpen Stealth Proto, is a single-seat, twinjet, all-weather, stealth, fighter aircraft developed by Jundroo Aerospace Corporation for the SimplePlanes Air Force (SPAF). The Stealth-Pen is a next-gen advanced variant of Jundroo's Pigpen, the all out air-to-air combat machine. Different with it's predecessor, the Stealth-Pen features a multirole capability that allow the pilot to attack both air and ground target, and the ACRO mode feature has been removed from the next-gen variant. And the plane itself is still under development. In the other words, still a Prototype.
