China's Jiangsu A-Star Aviation Industries Company (A-Star) used the first Beijing exhibition promoting "civil-military integration" to reveal new combat aircraft electro-optical systems, some of which may be slated for the country's fifth-generation fighters.

A-Star's booth featured images of a Shenyang Aircraft Corporation J-31 fifth-generation export fighter to highlight two electro-optical systems, although it is not clear that A-Star's systems will equip future developments of this fighter, revealed as the FC-31 at the November 2014 Zhuhai Air Show.

The EOTS-89 resembles the Electro-Optical Targeting System (EOTS) of the Lockheed Martin F-35, which combines Forward Looking Infrared and Infrared Search and Track (IRST) capabilities. The similarity includes the use of two tracking mirrors and a flat-facetted optical window, with bottom fuselage placement just aft the radar radome. Such a system was so placed on the large mock-up of the FC-31 seen in November 2014.

The AUEODS system by A-Star uses two wingtip mounted pods that combine a domed IRST with a conventional targeting pod.

Shown placed on the front starboard side of the J-31 canopy, A-Star's EORD-31 serves as an IRST, similar to the OLS-27 series used by the Russian Sukhoi Su-27 fighter. However, instead of a spherical dome cover, the EORD-31 is flat and facetted. Chinese press reports claimed the system may be able to detect a Lockheed Martin F-22A at 110 km and a Boeing B-2 at 150 km.

Also on display was an image of A-Star's "AUEODS" system, which uses TX-S55 and TX-S56 pods which combine a conventional targeting pod with an over or under-mounted domed IRST. These two pods were shown on a Su-27 on the wingtip position taken by SORBITSYA electronic warfare pods.

Chinese press reports claimed it can detect targets out to 200 km, or 70 km for the F-22A and 120 km for the B-2. The reports also claim it can detect a Tomahawk cruise missile out to 18 km.

A-Star used the 2014 Zhuhai Air Show to reveal its F-80 medium-range air-to-air missile with a unique five flat facet for its infrared/imaging seeker. While its range has not yet been disclosed, A-Star used the recent Beijing exhibition to indicate it has a ground-attack capability.

A-Star's range of products also includes the five-seat German Extra EA-400 turboprop powered light aircraft, obtaining co-production rights in 2013.

"גנבנו לאמריקאים את תוכניות הייצור של המון מערכות מתוחכמות, עכשיו בואו עליהם קופה יפה!"

א. אף אחת מהמערכות לא מזכירה תכן של מערכת אמריקאית שאפשר לגנוב. אם כבר, העתקה/ייצור ברשיון של מערכות רוסיות.
ב. ברמה הזו אי אפשר "להעתיק תוכניות". מה עוזרות התוכניות אם יצרן החלונות לא ימכור לך חלקים, לגלאי יש מגבלות ייצוא, כרטיס התקשורת מתאים לפרוטוקול שאינך משתמש בו והמעבד הראשי כבר מיושן ולא זמין?
