Lockheed Insists F-35 is Worth the Wait, Cost
The reduced radar cross-section of the F-35 allows it to evade most enemy air defenses, both airborne and ground-based.

Low observability The reduced radar cross-section of the F-35 allows it to evade most enemy air defenses, both airborne and ground-based. Program officials note that stealth features on the aircraft have been traded against cost, so it is not as stealthy from all aspects as, for instance, the F/A-22 Raptor. But still, low observability (LO) on the F-35 comes at a price in payload: each of the two internal weapons bays can carry only a single air-to-air missile plus one air-to-ground weapon.
