Reduces the chance of a large-scale war broke out after the end of the Cold War, the countries are to slash the defense budget, thus slowing down the development of military technology footsteps. In recent years, the development of ground-based weapons mainly focus on R & D focus, in particular, is based on the operational requirements of the U.S. military and its allies in Iraq, Afghanistan, the strengthening of the local performance of existing ground-based weapons and equipment in response to regional conflicts and the war on terror. In this case, most of the major ground weapons continuation of the development of the end of the Cold War, has also introduced a few brand-new concept of a new generation of ground-based weapons R & D projects, but these programs have been reduced, delayed, or even end up with the fate of dystocia . In addition, the advanced countries of Europe and the United States also substantially reduced the scale of development of the Navy, U.S. Navy, for example, a new generation DD (X) destroyer, CG (X) cruiser, are downsizing, or changed the construction cost and technical risk than low warships. Naval equipment development has entered a period of low swing, this is a global phenomenon, the European and American shipyard and naval weapons and equipment manufacturers therefore restructuring to adapt to the new business environment. Countries lack adequate funding situation, the Future Combat Systems Program and more forced to cancel today to replace a smaller, lower cost and technical difficulty weapons development program, and the degree of innovation of science and technology has been significantly compressed.
