"To achieve lower costs the JSF accepts notable aft sector stealth limitations, especially when tackling deep or layered air defences with fighter threats - an acceptable tradeoff for shallow littoral and FEBA area battlefield strikes against predominantly short range mobile air defence systems. The aim in the JSF is to use newer materials technology than the F-22A does to reduce stealth costs, although we are likely to see this technology migrate across to the F-22A in later blocks." http://www.ausairpower.net/APA-JSF-Analysis.html http://www.ausairpower.net/APA-JSF-Analysis.html
