"The purpose of this concept is to describe 'naval operations in the littoral environment in light of emerging threats' in order to provide a unified framework for Navy-Marine Corps innovation. It places a renewed emphasis on fighting for and gaining sea control, to include employing sea-based and land-based Marine Corps capabilities to support the sea control fight. [...] This concept introduces ideas on how naval forces could be organized, trained and equipped to enhance their ability to operate in contested littoral environments. Included among those ideas are: additional, versatile force options; a wider application of existing doctrine; and the more flexible employment of current, emerging, and some potential capabilities. To confirm their integral merit, the ideas put forth in this concept require further testing and refinement through detailed wargaming, experimentation, and exercises. It is expected that these activities will invigorate and advance naval operational art and stimulate creativity on how to exploit the inherent synergy of integrated Navy and Marine Corps capabilities. Of particular importance, practical application of the concept during live exercises will allow naval forces to identify the inevitable seams and capability limitations that must be resolved."
