As the U.S. military pulls out of Afghanistan and “resets” for the Pacific theater, will there be an accompanying shift in the Defense Department's intelligence, surveillance and reconnaissance forces? The year should see the beginning of a shift away from lower-tech systems geared to detect improvised explosive devices and toward future high-tech sensors.

Dozens of women are filling senior management positions across aerospace and defense, changing the face of an industry not known for diversity. Another glass ceiling will shatter on Jan. 1, when Marillyn Hewson (right) becomes CEO of Lockheed Martin and Phebe Novakovic fills the top spot at General Dynamics.

The U.S. Ground-Based Midcourse Defense system, which has not had a successful intercept since 2008, is expected to return to flight in early 2013 after a two-year hiatus. And the U.S. will continue to roll out its Phased Adaptive Approach to protecting Europe, including construction of the first Aegis shore-launch site in Romania and further flights of the improved SM-3 Block 1B interceptor.

Decisions in 2013 could reverberate for a decade

Commercial, defense aerospace set to follow divergent trajectories.

Weeks after North Korea's successful rocket launch, South Korea may take steps to beef up its surveillance capabilities. On Dec. 21, the Defense Security Cooperation Agency formally notified Congress that South Korea has proposed buying four RQ-4 Block-30 Global Hawks for up to $1.2 billion. The sale of Northrop Grumman's high-altitude, long-endurance UAV would help South Korea assume the lead in intelligence gathering as the U.S. plans to dissolve the Combined Forces Command in 2015, notes the agency.

The Pentagon continues to set the standard for research and development spending on missile defense, though purchases from allies are increasingly setting the production pace for regional defense systems. This trend is likely to continue in 2013, as Iran threatens Israel and other U.S. allies in the region.

Could optionally piloted vehicles (OPV) be the next wave in cost-effective special-mission aircraft, able to fly in civil airspace with pilot and sensor operator on board but also capable of flying unmanned for far longer duration at lower cost than the Beechcraft King Airs so favored today? Aurora Flight Sciences and Northrop Grumman would answer yes. Aurora is developing the $4.5 million Centaur OPV, and its first buyer is Switzerland's Arma-suisse, which will use it as a flying testbed for unmanned-aircraft airspace integration.
