The Lockheed concept (the one in the video) is on the left. The one in the test had 12 KKVs (not including the carrier vehicle which may or may not be an additional kill vehicle) but there appears to be spots for 16 small KKVs. GBI could carry this and likely KEI as well. SM-3 would appear to be out in the cold with this concept.

The Raytheon concept is on the right. The larger missile shown is GBI and the smaller KEI. As you can see KEI carries more than six (haven’t had luck yet in tracking down the article that had specific numbers).

The Lockheed carrier vehicle has a 512 x 512 sensor array. Don’t know what it’s smaller KKVs have but then they don’t need a big array because the carrier vehicle will get them close before their own arrays take over. The Raytheon KKV has a 256 x 256 array so it won’t be as capable as the one on the Lockheed carrier vehicle.

It is going to be very interesting to see who wins this!
