Let me explain what the MSNBC article is saying. There are people in the Army who have the power to test, integrate, and field Trophy. To do that, it takes time, lots of time, and the Army is slow. The article also does not mention whether or not the Israeli Ministry of Defense will let us buy the systems. We test foreign systems all the time, but that is the easy part, fielding in quantity is much harder. Regardless, there are many, many systems that could help our troops, and they all take time to get into the hands of the soldier. Trophy is only one of them. 16 months isn't a long time in government procurement.
This MSNBC article has simply latched onto the fact that there happens to be an FCS program to develop a Trophy-like system, and has correlated that this is the sole reason that Trophy is not fielded. I don't agree with their opinion-passed-on-as-fact. Some people at the Pentagon agree, and there may be some truth in that politics play a part. But there is ALOT of this story left untold, and I know how programs can get distorted when someone (such as a reporter) makes a judgement about the program without knowing the whole story. You could make this same correlation with a hundred different systems that seem promising on the surface but haven't been fielded. And FCS is HUGE, there is a "system" to do everything. It wouldn't be hard to find an FCS program that is tasked to develop something that has already been developed.
