Biggest hovercraft yet prepares for sea trials

IT IS haze-grey, travels on a cushion of air and is Singapore's biggest hovercraft yet.

This is a sneak peek at ACV-1, being prepared for its first sea trials by shipbuilder Singapore Technologies Marine (ST Marine).
The hovercraft - 'Air Cushion Vehicle 1' - is being fitted out at ST Marine's yard at Benoi Basin in Jurong.
When ready, it will travel at high speed on land or water on a cushion of air forced under its hull by powerful fans.
ST Marine spokesman Laura Chua declined to comment on ACV-1 or its capabilities.
A check with Jane's Fighting Ships, which lists almost all naval hovercraft the world over, and makers of civilian hovercraft showed no hovercraft similar to ACV-1.
This could mean the hovercraft is of local design or a new design developed with a foreign partner.
A Straits Times photograph of ACV-1, taken in late January when the shipyard was open to the media for the launch of another vessel, gives a good indication of its size.
It is about 45m long and has a drive-through cargo deck, which vehicles can enter from either the bow or the stern using a hydraulically operated ramp.
Hovercraft can hit the beach regardless of tide and are not affected by underwater obstructions such as large rocks, which can damage conventional landing craft.
This gives hovercraft like ACV-1 the ability to land cargo on virtually any coast.
Such capabilities are likely to interest the Republic of Singapore Navy, especially after the tsunami relief operation in Meulaboh in Sumatra when army combat engineers had to toil for hours to remove debris before beaches could be used by its landing craft.
ST Marine's foray into the specialised field of hovercraft comes after an 18-year break.
In 1987, when the company was known as Singapore Shipbuilding & Engineering, it unveiled the Tiger 40, a prototype 16m-long hovercraft with an aluminium hull, jointly developed with a British company, Air Vehicles Ltd.
After a series of sea trials and a marketing drive that failed to find a launch customer, the project was dropped.
The prototype Tiger 40 was abandoned in a carpark at the Benoi Basin yard
Such weapons are good for morale for the crew (esp, with the GPMGs firing) but they are practically useless against attacks from aerial attacks or even small anti-ship missiles such as EXOCET-class missiles.
