situational awareness," he said.
The upgraded radar can also detect a target up to 80 nautical miles away -
twice the distance than before, and track up to eight targets.
"There's no need to see the target. We can just drop the bomb from far away without being getting shot at," he added.
Major Jaspal Singh, RSAF's operations manager for the F-5S, added: "Its major selling point is that the avionics are similar to the F-16s and F-18s. It's
not just an F-5, it's a whole new plane."
Well, sort of. Acquired by the air force in 1979, the F-5Es as they were
known then, were Singapore's first supersonic fighters.
.........................................
Now, the upgrading of the RSAF's entire Tiger fleet of about 40 planes has
been completed, at about $6 million a plane. This is a bargain considering
that a brand new F-16 costs about US$25 (S$43) million.
The upgrading has given the F-5S an additional lifespan of 10 to 15 years
each.
As for sceptics who think that the upgrade results in only superficial
changes, Mr Lim Tau Fuie, vice-president of avionics in STA, had this to say:
"It's now a much more effective plane than what it used to be.
"If there were no benefits, then other air forces like the Turkish Air Force
wouldn't have gone for it."

DEFENCE engineers here made an explosive breakthrough recently that could radically change the design of military bunkers and civilian bomb shelters.2. More than 6 years of effort to confirm water as buffer
After experiments showed that water-filled containers could help absorb the
destructive power of a bomb blast, engineers from the Defence Science and
Technology Agency (DSTA) held a full-scale trial with their counterparts in
Sweden, blowing up 10 tonnes of explosives.
Packed around the 10 one-tonne lots of explosives - each capable of punching a 3m-wide crater in the ground - were containers filled with two tonnes of water each.
On detonation, the containers were wrecked. But the energy from the
explosion vapourised the water, reducing the effect of the blast by 60 per
cent.
Hailing the results as a major breakthrough, DSTA chief executive Richard
Lim said yesterday that defence engineers worldwide had considered using water barriers to reduce the effect of an explosion.
But none had tested the idea on the scale of the experiment conducted in
Sweden last month. He added that the experiments are important as water
barriers can potentially reduce the amount of land needed as a safety buffer
around ammunition bunkers.
Mr Lim updated the media on research developments at DSTA when he unveiled a 60-page book to mark five years of DSTA's achievements.
The book will be distributed to organisations such as government bodies,
tertiary institutions and public libraries.
DSTA was formed five years ago from several Ministry of Defence departments to serve as the national authority on weapons procurements and military technology.
Mr Lim added that another area his engineers are working on is to help
national security planners assess the impact of a bomb blast, similar to the
car bomb detonated outside the JW Marriott Hotel in Jakarta. The August 2003
terror attack killed 12 people.
'One of the scenarios that we are looking into is the extent of building
damage and casualties in the event of a car bomb exploding near or at the
entrance of a hotel, similar to the attack at the Marriott,' he said.
From its analysis, using computer modelling and other tools, DSTA will
recommend measures to minimise casualties and damages, if not prevent an attack.
In undertaking this project, MINDEF achieved a number of ground-breaking results in R&D. Significant achievements have been made in water mitigation and ground shock studies. Water mitigation makes use of water to absorb the energy of an accidental explosion. This greatly reduces the safety buffer zone, freeing up land for productive use. Ground shock studies enables our engineers to formulate structural engineering codes for the safe construction of buildings in areas affected by ground shock effects. This also reduces land wastage.fr Speech by Mr David Lim, Minister of State for Defence and Information & the Arts, at the Ground-Breaking Ceremony for the Underground Ammunition Facilty Email Article Dd: 12 Aug 1999,
The Crisp facility can now remotely control the Ikonos satellite's cameras for 20 minutes daily and sell images.fr STimes 31/08/2001 Page: H13
FOR about 20 minutes each day, a research centre here has the opportunity to operate the most powerful commercial space satellite in the world.
Orbiting 680 km above the earth, while travelling at 25,200 kmh -
10 times the speed of a bullet - the satellite is capable of delivering
images that show buildings, roads, bridges and cars.
In forested areas and plantations, even individual trees can be
distinguished.
From a ground control station at the National University of
Singapore, the Centre for Remote Imaging, Sensing and Processing (Crisp) now remotely controls the cameras of the Ikonos satellite
when it is within a 2,300-km radius of Singapore.
This allows it to see everything up to Hainan Island to the north,
Sumatra to
the west, Kalimantan to the east, and the area around the waters
off Java, including Christmas Island, to the south.
Since April this year, Crisp has been processing images from
the satellite, which can deliver full-colour images at 1m resolution,
which makes cars and individual trees clearly visible.
Crisp officially opened its Ikonos data reception and processing facility
yesterday.
Under the commercial agreement with Space Imaging, the US-based owner of Ikonos, raw images are beamed from the satellite to Crisp's receiving station at NUS, which then processes the images before selling them. Crisp and Space Imaging share the profits from the sales.
An image covering 100 sq km can be priced between US$4,000 (S$7,000) and US$4,500.
Mr Conrad Mueller, vice-president of global alliance for Space Imaging, said:
"This new capability provides Singapore with the ability to have timely,
high-resolution imagery in detail never before available."
Mr Kwoh Leong Keong, director of Crisp, said it was already selling images of
oil-palm plantations in Malaysia - complete with a pinpoint calculation of the
number of trees there - to companies interested in buying or selling these
plantations.
Other uses of the images include monitoring land reclamation, he added.
Crisp was set up in 1992 to collate information and conduct research for the
business and scientific communities by receiving and tracking data from
satellites.
Several satellites, circling the earth twice every three hours, send a
continuous supply of pictures.
Now it also has access to the US$700-million Ikonos, which orbits the earth
about 14 times a day. But it zips over the area covered by Crisp in only two
of the 14 orbits.

RSS CHALLENGER is an ex-Royal Swedish Navy, Sjoormen Class submarine that was acquired in 1995 as part of the RSN's submarine training package.

The submarine is to be used by RSN crew for training in Sweden.fr http://www.mindef.gov.sg/imindef/news_and_events/nr/1997/sep/27sep97_nr3.html
Fortunately, these failures and shortcomings are finally and slowly becoming public knowledge in the United States, for as the Congressional Budget Office revealed in 2001: “Some analysts argue that the Navy is not very good at locating diesel-electric submarines, especially in noisy, shallower waters near coastal areas. Exercises with allied navies that use diesel-electric submarines confirm that problem. U.S. antisubmarine units reportedly have had trouble detecting and countering diesel-electric submarines of South American countriesfr http://www.cuttingedge.org/news_updates/nz1839.htm
Finally, during RIMPAC 2000 it was reported that H.M.A.S. Waller had sunk two American nuclear submarines and gotten dangerously close to the carrier U.S.S. Abraham Lincoln. Even more ominous, asserted researcher Maryanne Kelton, is that: “Even though the exercises were planned and the US group knew that Waller was in the designated target area, they were still unable to locate it.
In 2001, the unusually candid skipper of the nuclear submarine U.S.S. Montpelier (Commander Ron LaSilva, U.S.N.) recounted that a Chilean diesel submarine "Shot him twice during successive exercise runs.” As a result, LaSilva learned that “bigger and nuclear is not always better.” Commander LaSilva should be commended for his courage, for as we shall later in this paper, this kind of honesty is usually not the best policy for U.S.N. officers.
