U.S. Looking at Israeli Iron Fist APS

From Wiki

It looks like the US military is far less sanguine over Raytheon's Active Protection System (APS), Quick Kill, because the military folks at the AUSA convention were all over the Israeli Iron Fist APS, made by Rafael.

It is similar to, but appears to be a somewhat more capable system than the other Israeli APS, IMI's Trophy system, in that it can engage KE rounds as well as ATGMs and RPGs.

The concept is somewhat different than both Raytheon's and IMI's, with the blast intended to take out incoming missiles and sabot darts, as opposed to shot, which means that the sabot is not actually destroyed, but made to yaw prior to impact, which would reduce penetration.

When one considers that the Israeli standard infantry fighting vehicle is the Namer, which is based on the Merkava chassis, and weighs in at 60T, as versus 40T for the Bradley, the 20T Stryker, and the 20-30T FCS replacement, it may be of somewhat more limited utility.

A sabot yawing 15° or so off the normal may not prevent penetration of the thinner armor, but on the plus side, using of a non-fragmenting charge means that the potential to injure troops operating closely to the vehicle is significantly reduced.
