US Missle Sheild Upgrade Posted on November 6, 2008 by Robin The missile shield will be upgraded by multiple kill vehicles being carried up by as a single payload in a rocket. There are two competing tenders: Lockheed Martin and Raytheon. Lockheed guides the mini rockets from a central command unit, Raytheon’s system has each of the warheads acting as a seeker / controller in theory, but one of them becomes a master after launch and transmits the targetting plan to the other vehicles.
