How to Counter Cruise missile threat

[ajay_ijn]

Every one knows that cruise missiles are a Big threat to surface warships of every kind.

What measures are navies taking to protect their warships from cruise missiles Especially the navy eqiupped with an Aircraft carrier becoz it will be the prime target.

Considering the facts of Sinking of an isreali destroyer and Damage of an US frigate even a high subsonic speed,low flying cruise missile like Switch blade or harpoon is a threat,leave alone the supersonics.

More than 90 countries of the world are having cruise missiles.

CIWS and AEW/AWACS are going to play much role in cruise missile defences.

This topic is not discussed much in the forums so i created the thread.

At an individual platform level, most modern navies operate a layered system to defend against ASM's. Modern warships operate a variety of radar systems to scan for, identify, target and provide fire control against potential threats.

The first (or last depending on your point of view) is the Electronic warfare systems and decoy systems a ship carries, these include ESM and "Electronic Attack" chaff and flare dispenser systems and "active RF decoy's" such as Nulka systems.

The second layer is the close in missile defence systems. These currently comprise gun and/or missile systems. Common examples of these include the US Mk 15 Phalanx 20mm gun, the Dutch/British Goalkeeper 30mm gun, Russian AK 230, 30mm Gun and the Spanish Meroka 20mm gun.

Missile systems are also increasingly being used to provide close in defence. Popular systems include the US Mk 43 Rolling airframe missile (RAM, 20 missiles) system or it's newer version SEA RAM, (11 missiles), the French Mistral SAM using the SADRAL launcher (6 missiles) or the Israeli Barak SAM system.

Other systems are now becoming popular which are being specifically designed for the ASM role with anti-air as a secondary role. Such systems include the Evolved Sea Sparrow missile system (ESSM) and the Aster 15. These are typically longer ranging missiles (up to 25klm's or so) that are becoming the primary response to an ASM attack (at least in "Western" ships).

Longer ranging systems include the SM-2 (soon to include the anti-ballistic missile Sm-3 version and a new ultra long range SM-6) and other systems such as the Aster 30, though these generally undertake the anti-air role as opposed to the Anti-ASM role.

Anyone else have anything to add?.

- The USN CSF's also used to operate with a "goat". That vessel is designed to act as a seducer and can emulate the signals and electronic profile of the Carrier.

- USN and a few other allied navies train against supersonic cruise missile attacks by using other missile systems. eg, the USN uses a missile system that can be tuned to emulate a Yakhont or a Sunburn. In the past they have used modified kh-31's, but these were eventually abandoned due to under performance issues.

- a USN CSF (for example) also uses active electronic masking. This has been around in conceptual iterations since the early 1960's. Onviously there is a contemporary version in use now.

- A typical CSF also has a layered screen. At a warfooting that screen starts to give intercept layers at the 1000km mark and progressively peeled back for depth and intercept responses.

the Dutch/British Goalkeeper 30mm gun

:mad Raaah! It's Dutch! :mad

GOALKEEPER has been tested by a joint team of the United States Navy, the UK Royal Navy and the Royal Netherlands Navy but is otherwise a product of Thales-Netherlands (formerly Hollandse Signaal Apparaten, or Signaal for short) employing a US-developed gun and gun mount.

Most of the cruise missiles are having less than the range of 300km
so the enemy ships must come atleast 300km near to Carrier and can be sunk before it launches the cruise missile.
If the destroyers and cruisers are upgraded with Rolling airframe missile and ESSM will surely enhance the defence.
The most important part would early detection by E-2C hawkeye as it will give more time for the defensive systems to calculate and intercept the cruise missile
But i don't think E-2C hawkeye is having the capability of low flying cruise missile detection

Without going into detail:

A GAO report on cruise missile defence is about as useful as the Enyclopaedia Britannica is on how to do a moonshot. It's far from complete (naturally) and gives only a very superficial "technical" comment. In short - it's for politicians so it's dumbed down.

E-2C Hawkeyes can certainly detect cruise missiles - what makes you think that they can't?

 

[Aussie Digger]

most AWACS can detect low flying missiles, be they cruise or otherwise, but they are such a scarce resource for most countries that they could only rarely be employed to specifically protect a naval group (other than the US). Modern X band radars can detect cruise missiles at extended ranges as well, thus reducing the need for the AWACS for naval elements anyhoo.

Sorry Tatra, I wasn't trying to upset you...

That's ok, the cheeseheads just got a bit touchy ever since Thales took over ...

Hi

A good way to defeat sea skimer anti-ship missile will be the eletronis Scaning radar systems. THey are able to track a lot off targets at some time.

The convencional syestems uses two radars equipament, one for long rage detection wich operate in long waves, and a ilumination radar wich operate in shot waves. So The nunber of targets that can be engaged at some time depends of the number of iluminmations radar, frigates and destroyers uses normaly 2.

Ships with a eletronic sccan radar can engage much more tha 2 targerts. Is is used by US AEGIS system snd now they will be used by europeans navyes, like ASTER system wich will use the french made ARABEL eletronic scaner radar

The ASTER was tested and it have hit a sea skimer target at hard eletronic everyoment
