The IAI Heron, and the Elbit Hermes 450 are the two that are most in use by the IAF. Both are MALE (Medium Altitude Lone Endurance) type UAVs. Most
likely what you are hearing is the Heron, as it has a much longer endurance, and is capable of a higher altitude where it can stay out of range of
everything but a dedicated AAA gun, or a missile.
The
Heron is capable of 45 hours of flight, at altitudes near 30,000
feet or higher. It's fairly short ranged, but in this case, that's not a problem, since they're staying close to home. It's mostly used for
reconnaissance missions over land, and maritime situations.
The
Hermes 450 is a popular export model, that is even used
in the US. It's capable of about 20 hours of flight, at an altitude up to 18,000 feet. The Hermes is more for SIGINT, ISTAR, and comm relays than
it is for a tactical situation.
