Aurigny is first European operator to use satellite approach system

Unmanned vessels are about to take a leap in capability, on the surface and beneath. The desire for persistent sensing is driving the need to develop fully autonomous, long-duration vehicles that can covertly patrol coastal waters or overtly follow submerged submarines. The U.S. Office of Naval Research plans to build prototypes of the Large-Displacement Unmanned Underwater Vehicle (LDUUV) to address the autonomy, sensing and energy challenges of a vessel able to operate independently for months.

To lower costs, Pentagon could turn milsat procurement on its head.

North Korea's successful launch of a satellite in December after 14 years of attempts put the hermit kingdom one step closer toward deploying an intercontinental ballistic missile. And Iran's nuclear weapons program—and the threat of an Israeli attack to cripple it—will keep tensions simmering in the Middle East.

When I began writing this column eight years ago, airlines were reeling as oil prices soared above $50 a barrel. Lockheed Martin was hoping to ramp up production of the Joint Strike Fighter in 2009, and Wall Street analysts were beginning to question whether a run-up in defense stocks had much steam left. Airbus was preparing to launch development of the A350 in response to Boeing's 7E7 (now 787), and the business jet market was embarking on a sales surge that would end in a spectacular crash.

The bifurcation of the business jet market is expected to continue in 2013, with strong demand for larger and pricier jets and sluggish sales of small and mid-sized aircraft. A Chinese company's failed bid in 2012 to acquire bankrupt Hawker Beechcraft is unlikely to slow Beijing's bid to become a significant player in the market.
