Besides the simple power of a new missile, there's an element of national pride at play in the long-range weapon system. Last March a Turkish government defense official told an industry gathering that "If Turkey opts for direct purchase of the system then it will be obliged to make new off-the-shelf purchases 15 or 20 years later. We will not settle for this. Our target is to gain national technological capability in the missile project." Any new Turkish missile is likely at least a decade or two away from deployment, so Turkey researching long range weapons won't change the situation in Syria. It does, though, along with the Russian weapon deployment, signal a future with lots of missiles waiting on the ground, and fewer planes flying.
