Design & study: Konstantinos Panitsidis
Declaration
The K.P.S. projects have been studied in detail. However, in this presentation, the three-view drawings, as well as the results of the calculations, have undergone a partial, deliberate distortion to discourage the production of counterfeit copies.
The Hermes 2904 is based on Yetos and is an AWACS type of aircraft, with a 6 member crew, consisted of captain, co-pilot, control-officer, information-officer and radar operator.
It's equipped with advanced surveillance systems for observation of land vehicles and surface naval ships.
It has advanced ECM and ECCM, active and passive and powerful computer stations.

EQUIPMENT: Observes terrestrial vehicles and surface ships. Incorporates advanced ECM and ECCM active and passive systems and Computer hardware.
Radar: Detection range 320-350 km, height 0-30 km, azimuth 360 degrees, target detected range 200 km. Number of detected and tracked targets 120/240.
AIRPLANE INTERIOR LAYOUT: Four operator crew consisting of two air traffic controller Officers, one information's center Officer and a radar operation Officer.
