F-35, Stealth and Designing a 21st Century Fighter from the Ground Up
Stealth must be designed into the aircraft; it can NOT be done after the fact. VLO stealth must be planned for and built in. The designers must incorporate large internal fuel tanks, internal weapon bays, and internally mounted sensors with appropriate apertures. Another hallmark of 5th generation is agility, which goes hand in hand with stealth. In the third slide, the results from Northern Edge 2011 are shown. Although the F-35 airframe has not been flown in Northern Edge some it sensors have been. The sensors performed extremely well and portend a bright future. It is understood by most that the electronic order of battle will play a key role in future conflicts. What the exercise showed was that a stealthy 5TH Gen. fighter -- the F-22 -- with its ability to be forward deployed in contested air space In addition to its precision active and passive sensors were able to ID threats; EW sites, SAMS, AAA radars for entire package much sooner. The presence of 5th Gen fighters in the force package increases overall forces mission effectiveness by enhancing survivability and lethality for entire package. It showed as well that 5th Gen fighters enhanced battle-space awareness enhanced overall mission effectiveness of entire mission package And finally, the exercise showed that 5th Gen fighters with this enhanced SA tend to function as Air Battle manager for entire package. Even when F-22 was weapon bingo it stayed in fight as battle manager!
