Subsurface Threat

June 30, 2007 (LBO) – Sri Lankan security authorities plan to install underwater surveillance systems in Colombo harbour to enhance the defences of the port which handles most of the island’s trade. London’s Metropolitan Police said Chrishanthakumar is accused of receiving literature and manuals allegedly included information about underwater warfare and naval weapons systems and bomb disposal.

This year Tiger guerillas have been stepping up their campaign against economic infrastructure by bombing two petroleum installations with light aircraft.

An attempt to bring down a vital high tension powerline that fed the national grid from a key generating complex failed last month when a tower failed to topple when an explosive device went off at its base. The new measures are being taken to protect the port against Tamil Tiger attacks, senior defence and port officials said.

The surveillance systems are designed to detect intrusions by both submersibles as well as Tiger scuba divers.

Such systems were rarely available commercially and were found only with the world’s most advanced navies until recent years when the global Al Qaeda threat made maritime security a big business.
