HY-2 Silkworm

[Chizh]

There is a question on HY-2 Silkworm.

Maybe someone knows what radar is used in the coastal ASM HY-2 Silkworm missile site?

[Silver_Dragon]

I suppose can be a copy of the old S-2 antiship missile complex radars

 

http://weaponsystems.net/weaponsystem/DD06%20-%20S-2%20Sopka%20(SS-C-2%20Samlet).html

A typical S-2 Sopka battery consists of the following components:

4x B-163 trailer mounted launch rails. The trailer has two axles with double wheels, two jacks and two outriggers. The launch rail holds a single S-2 missile and can be rotated -85 to +85 degrees.

8x PR-15 single axle trailers used to transport and reload S-2 missiles.

1x Mys, Russian for Cape trailer mounted target detection radar.

1 or 2x Burun trailer mounted target ranging radar.

1 or 2x S-1M trailer mounted fire control radar.

1x Mius Search radar with 100 Nm Range

1x Burun target ranging radar with 50 Nm Range

1x S-1 fire control radar with 50 Nm Range

 

Some pics with 4K40 launchers and associate radars.

The Chinese system has unknown.

I think it might be the SQUARE TIE.

Very interesting! Thanks Dragon!

But I suspect that the Chinese have developed some kind of their own mobile radar.

S-2 Sopka battery is correct approach here.

Also, I think Iran would develop their own coastal search and target acquisition system.

[Cik]

hey, it is SQUARE TIE.

 

 

quoting international electronic countermeasures handbook p. 140

 

 

 

Initial detection is carried out by a type 254 radar, a version of the russian MR-331 Rangout (SQUARE TIE) the latter is a small, lightweight search radar operating in the I-band with a range of 130 km. it also acts as a fire control radar in larger vessels...

this source at least says it doesn't have any sort of midflight update capability and just flies into a terminal active using midcourse INS/GPS. so the radar serves only as target ID/orientation and not as any sort of guidance system apparently.

Could be something known or domestic...

I am sure this is applicable to ship-borne missiles as Square Tie is ship-borne itself. However, if we take 4K51 Rubezh system as an example you could be right as well.

 

Land-based missile batteries used to operate three radars as per S-2 Sopka (that's in the '60s though).

 

Modern Mys-M1E (trailer based) and MR-10M1E (stationary mast) combine the roles -- http://roe.ru/eng/catalog/naval-systems/stationary-electronic-systems/mr-10m1e/

 

Also, as Iran is apparently capable of manufacturing HY-2 missiles, it could be also true they can use something they built themselves, like Afagh coastal radar mounted on the truck.

 

"The truck-mounted radar associated with the HY-2 system provides surveillance and target detection facilities and is also stated to perform target tracking. The design apparently originates from a Soviet naval search radar and probably operates in the C-band of the spectrum"

 

This could also mean a truck with MR-331 Rangout (Square Tie) (as per Cik) or 3Ts-25 Garpun surface search radar.

additional info

[Baz000]

I found this info

 

http://articles.latimes.com/1987-10-17/news/mn-3719_1_surface-to-surface

 

says the missile is towed on trailer behind a radar guidance truck.

[Cik]

OK, so after some fairly concentrated digging i haven't been able to find conclusive proof that SQUARE TIE radars exist in iranian service, but i have turned up some evidence that

 

 

 

1. square tie radars (standalone land based) exist and

 

 

 

2. they were exported by china in the past

 

 

(see: SQUARE TIE export to bangladesh near the top)

i'm fairly convinced at this point that it's the square tie. nothing else i can find else fits the pattern of "surface-surface FCR" of that particular age. there are a bunch of other ship-based FCRs in the modern PLAN service but nothing it would make sense (imo) to integrate with an ancient ASHM.

That radar looks like Afagh to me.

The Silkworm's radar shows as a "U" on the RWR but is not visible from the HARM's  page? Any way to lock it up for a HARM launch?

The Mys-M1 is surface-search only, so not sure whether it would be classified as a threat emitter for aircraft, and as such I wouldn't necessarily expect it to be classified on the RWR and HARM.

Understood but it would still be cool to be able to take them out with a HARM!

Seeing as there is a post on the termite (a variant, I suppose), I will post this here.

This is the closest video, image, manual I have personally found to seeing what is done to fire silkworm. This is on an ex East German Tarantul missile boat. Note the gentleman talks about sending info from the 3TS 25E radar to the fire control unit (A3K?). The antenna of this radar looks markedly similar to the land based systems, in some cases inverted, on some upright. The fire control unit has many circular dials beneath indicator windows, which are beneath the auto populate button for guidance parameters. It is mentioned Regime 1 is a visual launch regime. It seems to me the radar is not a necessary component in engaging with the missiles, at least on the naval versions. Of course, it's much, much better than the eyes but it does seem an emission free attack with IR missiles is possible with external spotting support or with visual contact.
