That's why Mas Selamat couldn't have swam to Malaysia. Canoe,
maybe.
Some of the material in the first article is similar to the
document entitled - ‘Underwater Intruder Detection Sonar for Harbour
Protection : State of the Art Review and Implications – NATO
Undersea Research Centre - October 2006’
In 1984, there were reports of numerous unknown
intrusions into Swedish water that resulted in an accumulation
of ‘Swedish experience in hunting alien submarines near
top-secret naval base’.
Any explosive devices dropped into the sea - from hand grenades
to depth charges - can create cause different levels of damage to
the human body even when protected behind steel hulls.
The main assets of the Port of Singapore Authority are
all located in the south, and if your ‘Swimmer Detection System’ is
used - it will be unlikely to be installed as a protective screen
around the entire Singapore Island.
More likely, it will be used to protect selective high value
assets such as the RSN Bases at Changi and Jurong.
It is unlikely that Mas Selamat Kastari could have crossed into
Malaysia by canoe - not when there are the string
of Singapore Coast Guard patrol boats with night vision
equipment patrolling the coastline for any floating object larger
or about the size of a human body.
A small head bobbing in the water may escape detection, and even
more difficult to spot when quietly breaking water
surface every now and then to take a breath.
‘Mas Selamat Kastari escaped from Singapore northern
shoreline - either swimming or walking in the shallow waters
alongside the Causeway sloping embankment - to land on the
quiet Johor coast known as Stulang Beach in
Johor Bahru - next to the Johor Customs Lorry Inspection Terminal
and close to the Blue Wave Hotel ’
From the ‘History of Naval Manned Torpedoes’ - it
was developed as early as in November 1918, when two Italian
divers sank the Austrian cruiser 'Viribus Unitas' in Pola
Harbour.
In 1941 and 1942, during WW2 the Italians demonstrated
again the successful use of "Human Torpedos" to
attack British Naval Bases in Malta, Gibralta and
Alexandria.
These were naval divers - or "frogmen"
- riding on the torpedoes and releasing the torpedos at a
distance before swimming to safety.
Some of these Italian naval team were
captured alive with their equipment, and which allowed the
British to form their own Naval Diving Team after a year
of intensive training and development - which resulted in an
underwater ‘Chariots’ .
As WW-2 progressed, the British launched successful raids
to sink the Italian capital ships taking refuge in their naval
bases and prevented these potent capital naval ships from falling
into Nazi hands.
For the future protection of harbours and naval bases - we can
draw from the foreign R&D investments and solutions being
developed or available by the security industry -
‘New Generation Advanced Deployable System
(ADS) Undersea Protection Sensor Nets’
‘Maritime Homeland Defense & Force Protection Port
Security Solutions’

intruders – NATO Research Centre – October 2007’
