oversize lizard there who said the following:

HAHA. MORE RUBBISH!
Who is talking about OTH blah blah........the sub-launched missile
capability is to allow stand-off range capability lah.
And as MMC as posted, once launched, its entirely FIRE AND FORGET.
(
forgetting the missile...
)

The EXOCET SM39 Block 2 missile is the submarine-launched version
of the EXOCET family, with all its characteristics : all-weather
operation, sea-skimming flight, solid propellant, high kill
warhead. (
sea
skimming...
)
The missile has a range of 50 km, which enables the submarine to go
into action while remaining out of range of the detection equipment
and, even more importantly, the weapons of its surface enemies. (
right.... i am sure all the makers of AMM and CIWS
must be laughing their tooth off)
When launched the EXOCET SM39 Block 2 imposes few constraints on
the submarine depth, course and speed (
how about
distance to target?
)
note the part about his claim that he is not talking about OTH
but then talk about the exocet having 50KM range....
from what i know...
http://radarproblems.com/calculators/horizon.htm
assuming a sub at sea level... and a US NIMITZ carrier(the biggest
military ship i can find
)
with a height of 40 meter... the radar horizon is a mere
26km...
versus closer to home... against the RSN formidable... the radar
horizon is a pitiful 15KM (assuming the formidable height is
15meter), in reality... the detection range if far lower... since
most of the ships RCS is near the water then at the top where
sufficient radar echos can be detected. 
comparatively... the latest Gould Mk 48 Mod 4 heavyweight torpedoes
has a range of 50KM at 40knots (islamic states.. need not apply
).... stupid lizard still think about Stand off range of exocet
missiles...

so... unless the world is flat to the lizard brain... whats the
point of noteing the exocet range of 50KM?? 
but overall... its a good read.. and lots of nice article from
singalion about RSN sub.....
