Yes, they're sitting ducks. Other possibilities include UAVs
(unmanned airborne vehicles), satellites, local operatives
with noise jammers tuned to known cellular system frequencies,
and remote override via chip backdoor codes.
As for detection of stealth aircraft, a network of ham operators
could create a crude OTH (over-the-horizon) HF radar system
by transmitting "coherent cw"
(http://www.arrl.org/tis/info/cohrntcw.html)
at HF frequencies (3 to 30 MHz) with
a distributed computing system linked in real time via the Internet
to detect multipathed signals and perform crude triangulation.
This is based on the fact that stealth aircraft, especially the large
B-2, can be detected at HF resonant frequencies
corresponding to aircraft dimensions (this would not provide
precise location information).
You can observe this reflected-signal effect by listening
to a weak FM radio or TV station and noting the occasional
fluctutations in signal strength when commercial aircraft
fly overhead.
A more effective OTH radar system would use a global
network of undetectable UWB (ultra wideband) signals
(www.timedomain.com). We can expect such covert pirate
monitoring systems to emerge in the coming years
(possibly now operational?), with real-time Web display
of threats and counterthreats as warfare becomes

The above statements are all based on open, unclassified literature.
