Agreed that presently it is not possible for THAAD or Arrow to stop short range cruise missiles but you know missile defence technology is advancing very fast US THAAD system be able to defend their navel ships and coast through modification in THAAD system uptill 2010
Center for Arms Control and Non-Proliferation: Missile Defense Fails to Provide a Reliable Defense Against Short, Medium or Long-Range Missiles
This is from your own article:
Conclusions
Effective systems to defend against ballistic and cruise missiles, as well as rockets, artillery, and mortars, would benefit the security of the United States and its allies. However, there are exceptionally difficult technological problems involved; and despite the huge sums of money spent to date in attempts to develop defensive systems, none has yet proven effective and reliable.
Patriot, the most mature of the systems, has been under development since the 1960's, but it still has difficulty distinguishing between incoming missiles and friendly aircraft. Other systems, still in the developmental stage, have yet to demonstrate effectiveness under realistic situations.
Bottom line: there is no consistently reliable defense against long-range, medium and short-range missiles, cruise missiles or rockets, artillery and mortars.
Research should continue to try to develop effective missile and rocket defense systems. However, spending large sums of money to deploy such systems prematurely, before operational testing has verified that they will function as intended, should not be undertaken when programs to counter more likely threats to U.S. security continue to be under-funded. Moreover, national priorities for developing missile defense systems are inconsistent with the more likely threats as reflected in National Intelligence Estimates.
Your comment about 2010 cannot be verified by this article, they are planning but that doesnt guarantee that it will be fully effective. Also like i said its the PAC and arrow system thats been on table for India and not THAAD. If yes then what am i missing here. Also remember this that where on one hand the anti ballistic technology is growing, so are the missiles and their warheads getting advanced. Pakistan being a small nation with a very less defence budget as compared to its rival India cannot afford a anti ballistic programe at this stage, what we can however and hopefully do is to enhance our ballistic and cruise missile system so that if GOD for bid time comes, we are not taken by a surprise.
