Taiwan yesterday staged a major missile drill before President Hu Jintao boarded his flight for a high-profile visit to the United States.
Almost a third of the 19 missiles fired missed their targets, raising concerns that the island needs to further strengthen its defensive capabilities.
The misses, during unusually public live-fire tests in the presence of Taiwanese President Ma Ying-jeou, came days after Beijing unveiled its first stealth jet fighter.
Analysts said the first tests since Ma took office in 2008 - held at the Jiupeng air base in the south of the island - were aimed at sending a message to the US that Taiwan needs stronger defences in the face of the mainland's military expansion.
The drill involved 12 units from the army, navy and air force.
The 11 kinds of missile fired included Taiwan-developed Sky Bow IIs, which have a range of 200 kilometres, as well as US MIM-23 Hawks, RIM-7M Sparrows and FIM-92 Stingers. The island's Patriot anti-missile weapons and medium-range air-to-air AIM-120 missiles did not feature.
