Maximum connectivity would mean massively increased communications and sensor technology such as having an ability to achieve real-time connectivity with satellites, other aircraft and anything that could provide relevant battlefield information.The new aircraft might also seek to develop the ability to fire hypersonic weapons, however such a development would hinge upon successful progress with yet-to-be-proven technologies such as scramjets traveling at hypersonic speeds. Some tests of early renderings of this technology have been tested successfully and yet other attempts have failed.
The Pentagon's 6th Generation Fighter may be stealthy and will likely have next-generation computers, electronic warfare technology, speed, weapons and sensors.
Fighter jets in 20-years may likely contain the next-generation of stealth technoology, electronic warfare, sophisticated computer processing and algorithms, increased autonomy, hypersonic weapons and so-called "smart-skins" where sensors are built into the side of the aircraft itself.
Some of these characteristics may have been on display earlier this year when Northrop Grumman's SuperBowl AD revealed a flashy first look at its rendering of a new 6th-generation fighter jet. Northrop is one of a number of major defense industry manufacturers who will bid for a contract to build the new plane - when the time is right.
