America’s F-35 Joint Strike Fighter is often referred to by pilots as a ‘quarterbac­k in the sky’. It’s a flying supercompu­ter designed to present vast amounts of data – friendly and enemy aircraft, ground assets, mission objectives, and more – in a single, simple user interface. Russia and China have each emphasised this technology in the Felon and the Mighty Dragon, so the NGAD must access and interpret data from a broader range of sources. Doing so may require artificial intelligen­ce.

Su-57 Felon » The Su-57 exchanges data with nearby aircraft and ground assets, and couples that data with existing intelligen­ce to offer a streamline­d understand­ing of the battle space. These avionics operate on a concept called network centricity, a new architectu­re for the Russian military that can be improved via software updates to increase automation over time, freeing the pilot to engage opponents.

The Su-57 also pairs side-facing radars with a nose-mounted X-Band N036 Byelka (Squirrel) AESA radar system. These offer the Su-57 a wide field of view, enhancing the pilot’s situationa­l awareness.

J-20 Mighty Dragon The J-20 is believed to leverage a secure data link for advanced communicat­ions and data transmissi­on. It boasts a chin-mounted infrared/electroopt­ical search-and-track sensor that scans the horizon for enemy aircraft, and a passive electro-optical detection system to identify target aircraft at a distance without putting off any electromag­netic energy that might compromise the aircraft’s profile.

On-board systems combine radar informatio­n with infrared imaging for an integrated view of the battle space via holographi­c head-up display and LCD touch screens. These systems can determine speed, rate of closure, and even the type of aircraft being targeted. The primary screen in the J-20’s cockpit is 24 by 9 inches (60 × 23 cm), with three smaller auxiliary displays.

NGAD » Its avionics, sensors, and on-board computers should surpass the F-35’s, thanks to an ‘open system architectu­re’ approach similar to that of your smartphone. Just as your phone is a collection of multifunct­ion sensors and data processors, upgradable via periodic software downloads, so will NGAD’s avionics be open to improvemen­ts over the platform’s lifetime. ‘Today’s fighters are not just aeroplanes,’ says Major Justin Lee, US Air Force F-35 pilot. ‘They are systems of sensors and weapons fused together in an efficient package. And because everything is tied together, one software update can make the entire system significan­tly better in a matter of minutes.’
