BEIJING — South Korea has announced the deployment of two types of surface-to-surface weapons, one a cruise missile and the other ballistic. The Tomahawk-like cruise missile, which must be the previously reported Hyunmu 3C, has world-class precision, good enough to fly through a window, says Maj. Gen. Shin Won-sik, director general of planning at the defense ministry, who did not name either weapon. Its range is 1,500 km (930 mi.), he says.

Now it is official. Amid mounting evidence that China is serious about curing its weakness in engine technology, Avic says its highest priority in the coming years will be propulsion. The group has set a budget of 10 billion yuan ($1.6 billion) for aero-engine work over five years, though that figure is probably only a fraction of actual spending.

The hangars are flooded with seawater. Under the water, hundreds of tons of muck washed in by the tsunami cover the floor. All the equipment kept at ground level—which, at aircraft maintenance, is just about all of it—is ruined, some of it swept away. The customers' aircraft are floating about in the hangars and, with one remarkable exception, all wrecked. The buildings have just been thrown about by one of the most powerful earthquakes in recent history. The runway is submerged and, for all anyone knows, may have been smashed up by the earthquake. There is no power.
