Yup . . . And the USN and the the USAF do not agree on weapons and tactics.
"Not that all radars are created equal. Even back in the 1980s, author Andrew Cockburn warned that, ironically, the Soviet Union's oldest, crudest radars might detect stealth bombers that newer systems missed. Stealth aircraft rely on carefully designed shapes and thin surface coatings to baffle incoming radar beams. But the lower the frequency of the incoming radar, the longer the wavelength, which means the less it reflects such subtleties at all: It's essentially too stupid to be tricked.
The upside is such relatively crude radars may detect a stealth aircraft is out there somewhere, but not accurately enough to shoot it down. The low-frequency, long-wavelength radars that are most likely to see through stealth are, for the same reasons of physics, the least precise. They're also too big to fit in anything but a ship or a fixed ground installation, where they are typically used to give warning that aircraft are in the general area. Actually tracking and hitting a target depends on smaller, shorter-wavelength radars which can fit in, say, an interceptor aircraft or surface-to-air missile and which offer more precision but are also more easily baffled by stealth technologies.
"Just because you can see someone now doesn't mean you can kill them," said Deptula. "Acquisition radars, which are what people generally tend to focus on, are only one element in an adversary's air defense equation." After a target is initially "acquired," he went on, "you need to be able to track the asset to then get to a firing solution; then you need to transfer that tracking data to the missile, which then needs to be able to acquire and track the aircraft [after it launches]. Presuming that the missile can track... now the fuse needs to be able to detect the aircraft" in order to detonate at the right time.
Break any link in that "kill chain," and the stealth aircraft survives, even if it's seen. So while stealth can't defeat all the radars all the time, it doesn't need to."
