UCAS-D / N-UCAS concept

The idea of UAVs with full stealth and combat capabilities has come a long way, quickly. Air forces around the world are pursuing R&D programs, but in the USA, progress is being led by the US Navy.

Their interest is well-founded. A May 2007 non-partisan report discussed the lengthening reach of ship-killers. Meanwhile, the US Navy’s carrier fleet sees its strike range shrinking to 1950s distances, and prepares for a future with fewer carrier air wings than operational carriers. Could UCAV/UCAS vehicles with longer ranges, and indefinite flight time limits via aerial refueling, solve these problems? Some people in the Navy seem to think that they might. Hence UCAS-D/ N-UCAS, which received a major push in the FY 2010 defense review. Now, Northrop Grumman is improving its X-47 UCAS-D under contract, even as emerging privately-developed options expand the Navy’s future choices as it works on its new RFP.
