The DDS will rely on a version of the Trans-Phasic Missile (TPM) to protect against a future attack by the Clone Space Missile (CSM) which could be deployed by as early as the end of next year. The interstellar missile will be cloaked for most of it's journey but when it begins to enter the atmosphere of the target world like Proxima 7 then the cloaking device will be rendered pointless as friction and air resistance show up the missile.
TPM-A and TPM-G already offer a defensive capability against objects in high atmosphere or LEO but to combat a much smaller and faster target like a CSM warhead will require extensive improvements to the TPM guidance system. A new kind of TPM will be deployed (currently called TPM-AGX) which will detonate a proximity transphasic field explosion in front of the CSM warhead. This allows for a much greater chance of catching the warhead in the blast. A new motor with vector-thrust and improved control software will also mean the AGX is more agile.
However AGX is not likely to be deployed until some years after CSM, also the Clones will be continuing to improve their weapon. It is thought they will add decoys and other penaids to CSM 2.0 which will be the definitive production model expected in around 2114.
