Mission & Inspiration:
The ARD-20 “Roof Grazer” is Aeroryan Corporation’s ultimate expression of persistent aviation for the Republic of Aerolstad. Its name holds a dual meaning: operationally, it is designed to “graze” at the “roof” of the atmosphere—the stratosphere; creatively, it draws inspiration from the boundless daydream of sunlight and sky evoked by the tune Graze the Roof from the roof level BGM of the video game Plants vs Zombies.

Core Design: Powered by Light, Sustained by Flight
Featuring an ultra-long wingspan, the ARD-20’s wing surfaces are covered with high-efficiency solar arrays. Its nine electric propeller engines (simulated in-game with near-infinite fuel) enable silent, weeks- to months-long endurance cruises in the stratosphere, acting as a “pseudo-satellite.”

A Revolutionary Modular Platform
The “Roof Grazer” is more than a drone. Its broad wing roots are designed for various plug-and-play mission pods—from communications relay and meteorological sensing to wide-area surveillance. A single launch can perform multiple mission sets simultaneously, or modules can be swapped in-flight via companion drones, redefining the operation of high-altitude unmanned systems.

Aerolstad’s Eye in the Sky
As a symbol of Aerolstad’s technological prowess, the deployment of the ARD-20 marks the nation’s forward-looking commitment to green energy and cutting-edge aerospace. It draws power from the clear Northern European skies, silently watching over the fjords and sea lanes below.
