With Klub K you can put how easily 50 missiles on one cargo ship.
Yes, you can, but the first time you use such a surprise technique then any and all potential enemy forces have a clear reason to sink any Russian or neutrally flagged shipping in their vicinity... that would be expensive.
Experience in the falklands war showed civilian ships used as warship auxiliaries (ie cruise ships turned into troop ships, and transports in conflict areas) are at extreme risk because there is no design for battle damage and no self defence systems.
It makes them a liability in a war zone.
They are not meant to be use like tomahawks but they can be. I've red in the description of new exocet that they can be fired against coastal target with the gps (2nd possible role even if its primary role is antiship).
Not likely to be used against ships in port however... more likely to be used against port infrastructure or coastal and slightly inland targets.
Any ship can go 30 km from a military port if it's in the international waters. You can check on Google earth and see that in any big miitary port (in any country) there ar many ships. With electronic warfare instrument you can know what type of radars are there. If there just civillian radars you can attack.
Yes, they can of course go to a position at that distance, but what happens if the enemy has radars turned on scanning for threats?
Russian OTH radars operate all the time covering 6,000km ranges, and there will be plenty of other radars of all sorts of types looking for targets or just civilian air traffic or shipping.
Any attempt to jam radar will raise suspicion and attract attention.
A one off surprise attack might succeed but you can't base a missile design off such a strategy as a standard weapon. Cruise missiles in shipping crates allow a surprise attack via a large ship at sea or the potential to have an enormous attack potential at a train yard pretty much anywhere in your country... but when you sit them on the backs of your corvettes they are no longer "surprise" weapons.
A Russian Corvette with blue shipping crates on the rear deck will be clearly perceived as the threat it is... whether it is 30km from a port or 1,000km from a port.
Like it happened to Israel with the chinese missile. No radars ready, the attack succed.
And do you think the Israelis will let that happen again?
Do you think the other navies of the world will ignore what happened then and do nothing?
The US attack was on Lybia not lybian port. So ...
They struggled to manage 200 missiles for the air defence structure of Libya... do you think they will spare even a single missile for each rust bucket in port?
IF there are 10 ships (5 billion$) in the port, 50 kh-35 (around 35 million$) are worth it. Can be less if you want.
If they are worth half a billion US dollars each they probably have air defence systems that can defend themselves. Western navies are not that good at surprise attacks.
Most of the countries the west attacks don't have a worthy enough fleet to even bother with.
If argentinian navy had gps guided missile and did what I said before taking the falklands they would have them now.
First of all GPS is a US system and they can turn it off in any location any time they want.
During the Georgian invasion of South Ossetia the GPS system in the area was turned off so GPS systems would be of no use... and the chances of the Argentine navy sailing up to the UK and sinking the British fleet in port would be rather unlikely.
No it didn't happened because their is no more conventional war these days and these missiles are new. But you can be sure Israel would use a strategy like that if it has to face a bigger navy. A succesfull attack like this can end a war before it start if the opponents are separated by sea however.
I think you are misunderstanding the use of such weapons.
An Exocet is an anti ship missile. Adding GPS guidance allows it to hit fixed land targets, but it is not likely to be used to allow the missile to hit ships in port.
If you are going to use a missile to hit a ship in port in a fixed location surely it is easier to launch a Kalibr from 2,500km than to launch a Klub from 50km... both can be deployed from the same vessel but a vessel firing a Klub from 50km covers the first 2,450km at about 20knts and the last 50km at high subsonic speed, while a Kalibr covers the 2,500km range at high subsonic speed well out of air defence range of any country.
While I'm here, is it possible to make a navalized sub lunched R-77 with a bigger warhead (65kg) and a range of 40-50 km to use in mass attack against battlegroup by a new diesel clas sub ( a little oscar II). Like 40 missiles per subarine. Mach 3-4 sea skeaming. 65*40= 2600kg of explosives. I knwo it can't destroy them (If it's one or two ship it can) but it would dammage them badly and they could be finished by torpedo.
To be honest a sub would be better off attacking that battle group with heavy torpedoes.
The idea of subsurface launched anti aircraft missiles is interesting.
The Morfei, or 9M100 is a short range IIR guided missile designed to be carried internally in aircraft and launched via data link at targets it cannot see when launched.
By definition such a missile must acquire its target after it has been launched so it is fired and then it looks for its target itself.
Such a seeker would be very very interesting.
Such a seeker could be used for a sub launched anti aircraft missile... so sonobouys start splashing in the water... which tells you there is an aircraft looking for you... release a pod that floats to the surface with a pack of 5 missiles... one missile with its nose exposed looking for targets... if it spots a helo or MPA or UAV it can launch the other four missiles on the platform and itself at any or all targets detected... if there is nothing it can be recovered later by the sub.
For very long range missiles like the 300km range R-37M such a seeker would be very valuable as it is totally passive so you can launch the missile in the general direction of an enemy air field.
As it flys at mach 5-6 it can be looking for targets all the way without emitting radar like an ARH missile would... targets spotted could be identified and information sent back to the launch platform.. priority targets can be engaged automatically... like a recon suicide drone...
