March 22, 2008: The U.S. Navy has become the latest victim of electronic fratricide. In Iraq, its Silver Hawk UAVs [PHOTO] are getting disabled by interference from other military electronics...Investigation of these incidents revealed something electronic warfare experts have been warning of for a long time. With so much exotic new gear, capable of putting out so many different signals, and in a huge number of combinations (which creates even more new electronic signals), there was no way to knowing what kind of impact this would have on existing military, and civilian, electronics...In Iraq, is was quickly discovered that Warlock (a jammer that shut down enemy use of wireless signals to set off roadside bombs) also interfered with some military equipment, including some radios. This was not good.
The latest victim is the U.S. Navy Silver Fox UAV...The navy uses Silver Fox in Iraq to support its Riverine units. But most of the Riverine missions involve some truck convoy action, and that's where the Silver Fox is used to provide extra eyes for the sailors in the trucks. The Silver Fox did not always have problems with jammers and other electronic warfare equipment. But this stuff constantly changes, in response to whatever the enemy is using. The navy is looking at several fixes. In the meantime, there are some limitations on how Silver Fox can be used.
