of them as “towed transmitters” rather than decoys. When deployed pre-emptively, FOTDs can transmit sophisticated jamming
techniques in coordination with the jammer on the host aircraft
throughout a mission. It can also contribute to defeating a missile
if one is launched against the aircraft.
However, as an endgame solution, towed decoys have certain drawbacks. For one thing, the relatively short length (a
few hundred feet) of the towline means they cannot decoy
a missile very far away from the host aircraft to which it is
attached. This means that aircrews ideally want to position
the aircraft and decoy perpendicular to the incoming threat
in order to maximize the decoy-aircraft separation and avoid
aircraft damage from the missile blast. But, flying perpendicular (or abeam) of an incoming threat is often the worst aspect
for the aircraft in terms of its radar cross section. In addition,
a pilot is also limited in terms of maneuver. For example, depending on which direction the incoming missile is approaching the aircraft, the pilot does not want to position the aircraft
so that the missile flies past the decoy and detonates next to
the aircraft.
With an expendable decoy such as BriteCloud, maneuver is
still important, but it is much easier to achieve quick separation from a free-flying decoy. The drawback is the relatively
short transmit life of the decoy’s battery, and the speed at
which it can separate from the aircraft depending on how the
aircraft maneuvers. This can lead to situations in which the
decoy does not seduce the incoming missile away from the
aircraft. The point is that a combination of FOTDs and independent active RF decoys is probably the most effective countermeasures strategy against advanced RF-guided threats.
And, there is always the issue of cost. While Selex expects
BriteCloud to cost less than an ALE-50 (about $26,000-34,000
per unit depending on quantity), which itself is much less
than the cost of an ALE-55 at present production rates, budget
planners are not used to paying these prices when flares for
a fighter aircraft cost about $40-$200 per unit. However, with
no better alternative available, especially for the many nonstealthy fighter aircraft in service worldwide, RF decoys are
certainly value for their price. a
