RSN's Vastergotland SSK
-
Btw it had been old news that RSN bought 2 Vastergotland SSK...
Btw when will they be delivered or back to Singapore?
Btw these 2 are also second hand SSK from the Swedish?
Why did the RSN buy these old second hand SSK?
Why dun buy newly made ones or other more advanced submarines?
Since it is old second hand subs, it is bound to have lotsa problems when operating for a long period rather than a new one...
Wonder what is RSN's policy and plans when they bought these...
How will the Vastergotland and Sjoormen fare aganist the Msia Scorpene?
Btw heard RSN will decom 2 Sjoormen out of the 4 Sjoormen and send the 2 set of crews to man the 2 new Vastergotlands right? -
Haiz....sian.
Same old topic, bring up, talk talk talk, died down, someone will bring up, talk, talk, talk again, died down again, then it will return again..........
yawn.........zzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzz -
Much as I would like to see 4 or 5 new build Gotland (A19) class SSKs being ordered instead, the fact is that the RSN has already made its choice in the 2 Vastergotland (A17) SSKs.
However, be patient and expect future orders for brand new A26 next generation SSKs now being designed by Sweden, for which the RSN has already shown interest in.
I guess the RSN will place an order for 2 or 3 in the 2012-2014 timeframe, by which the 2 remaining Sjoormen (A12) SSKs will be around 45 years old. -
Navy has taken the conservative approach. Also, the upgraded subs though not top of the line, are big improvement over what we currently have. I believe they will also be fitted with Stirling AIPs. Who knows whether an older sub can prevail over a more modern one or not - sometimes superb tactics and strategy can overcome the older subs limitations.
Anyway, the subs are a bargain considering its capabilties. -
Thats true, new and pricey doesn't always equate to more capable.Originally posted by glock:

BTW any news on when these 2 newer submarines will be delievered? -
yah, during the Falkland conflict, the RN submarine HMS Conqueror employed a WW2 style torpedo attack in a fan shape to sink the Argentine light cruiser General Belgrano. Those were unguided torps.Originally posted by glock:Navy has taken the conservative approach. Also, the upgraded subs though not top of the line, are big improvement over what we currently have.

Wonder our subs use guided or unguided torps? -
I believe our subs ( and most other conventional subs ) use mainly acoustic guided ( active / passive or wake homers ) torps against other subs and heavy wireguided torps against large surface ships
-
oh I found out that our Sjoormen uses FFV Type 613 heavy weight torpedo which is wire guided.Originally posted by glock:I believe our subs ( and most other conventional subs ) use mainly acoustic guided ( active / passive or wake homers ) torps against other subs and heavy wireguided torps against large surface ships

so our navys has these AIP subbies ?
-
I believe that the upgrading of the 2 submarines have not been completed and they are not officially handed over to RSN. So strictly speaking we do not have them yet but its just a matter of time before it is delievered. The training course for the crew should already be running as of now.Originally posted by molgax:so our navys has these AIP subbies ? -
I am sorry but how does a Torpedo tracks it target?
How does a wire guided torpedo works? -
Just curious, with the wire-guided torp. won't the propellers or like buoy in the area snag the torp's guidance wire?
-
Torpedo works on active homing, something similar to an AMRAAM. Except that it receives commands from launcher through the wire. Only air dropped torpedoes are not wire guided.
Active homing is through a sonar build in the nose. It can go active manually or through build in algorithm. Once the torpedo is locked on, the high speed of it (40 knots) means the wire will be broken. -
hmm how about comparing it to TOW, just that a torp is Tube-launched and Wire-guided, only not Optically tracked (unless you do a WW2 style periscope attack)
I read that the americans sometimes use their Mk48 ADCAP torp as snapshots, ie use it to search and detect enemies instead of using the sub's own sonar. -
hmm. wouldn't that be rather dangerous if the wire snaps and the torp goes active?Originally posted by chillycraps:I read that the americans sometimes use their Mk48 ADCAP torp as snapshots, ie use it to search and detect enemies instead of using the sub's own sonar.
what recent conflicts have subs fired their torpedoes in anger anyway? -
I believe it was in 1982 Falklands War when HMS Conqueror sunk Argentina cruiser ARA General Belgrano.Originally posted by sgFish:hmm. wouldn't that be rather dangerous if the wire snaps and the torp goes active?

Subs firing Tomahawks would be more common though. -
We could get e newer TP 62 for our Vastergotland
-
wooo with nuclear jammer and can shoot laser guided torps and ICBMS and . .......Originally posted by spartan6:We could get e newer TP 62 for our Vastergotland

Any idea when the 2 new submarines will be delievered?

Thats a negative. Snapshot means u're shooting on bearing and ur torpedo is active the moment it leaves.Originally posted by chillycraps:hmm how about comparing it to TOW, just that a torp is Tube-launched and Wire-guided, only not Optically tracked (unless you do a WW2 style periscope attack)

The new ADCAPs has both passive and active homing IIRC. The wire guidance is primarily to guide the torpedo until it gets close enough to go active and ping on its own.
Wire guidance relies alot on the submarine's sonar. The Sub will track where the enemy is, and the operator will update the torpedo's course. And at a suitable distance, the operator can activate the torpedo without cutting the wires. (Cutting the wires would be default activate the torp's active homing.) Once active, the torpedo will ping the enemy sub or ship and guide itself.
Wire guidance gives torpedos an extra edge. You can set up elaborate traps with them. Swim them out at slow speed (quieter) at a loitering submarine, have them go different directions initially, and finally turn them towards the enemy submarine to close his escape and send the torpedos active. The enemy would probably take snapshots and whatever bearings they detect the torpedoes to be coming from but not at where you are! Its an art.
If you're interested in Submarine warfare or Anti Submarine warfare, I'd reccomend you give this game a try.

Note each torpedo (Mk42) costs US$1 million each

its target would cost more. Worth the bargain.Originally posted by touchstone_2000:Note each torpedo (Mk42) costs US$1 million each
