some questions..regarding f22p defence system , comparison & possible upgradation needs
A single optronic and radar above hangar for both CIWS.

the only medium airdefence the F22P has is 8 non reloadable FM-90 SAMs-China has developed a second to none CIWS for F22Ps, two seven-barrel gatling guns of 30 mm calibre mounted side-by-side on the aircraft hangar with the off-mount sensors in between, it is called the Type 730B, the gun is controlled by off-mount sensors Type 347G radar and the OFC-3 electro-optic director
Type 730B in either side of the hanger, with the SUR-17 in the background, search and fire control radars and backed up by an electro-optical sensor ‘ball' are visable in the centre line

The CIWS (Type 730) on the Pakistani vessel are without optronics in contrast with the Chinese vessel for example. Do they belong to a new type or they will be fitted with them later?

EDIT: The CIWS is Type730B with off-mount sensors


I believe that the class has inferior armament with Chinese analogues. Old anti-aircraft misisle system and CIWS that they share optronics.

need some insight into this

There is optronics. Without that how would the gun shoot?, this CIWS is not a machine gun that it is operated manually by like DMS sight .... This type 730b antenna and all are at the centre of both sides u can see it in first picture. This is off mount sensor system which means no sensors but This CIWS uses Electro-optics which is a branch of technology involving components, devices and systems which operate by modification of the optical properties of a material by an electric field. Thus it concerns the interaction between the electromagnetic (optical) and the electrical (electronic) states of materials. and it also has radar and F22p is first to incorporate this. Other type730 CIWS in PLAN currently uses optical sensor which in china is old tech the. This off mount system is their lates development and their new ships will have it.
F22p is excellent saying that it does not have VLS system instead has rolling sam i think that is far better the reload in war like situation i dont think VLS will also have any fast reloading system that is my personal opinion the better way to solve issue is use MAN PAD or I think is use BVR as sam's will give a reasonable range like 20km

A normal type 730 has an electro-optical director and a radar director mounted directly onto the gunmount. A pair of Type 730 gunmounts is typically support by a dedicated fast rotating high-data rate SR-64 search/track radar.

On the F22p we find 2 gunmounts, which are essentially Type 730 without both on-mount directors. These are aimed with 1 elop-director and/or 1 radar director, which are identical to the ones on Type 730. They are supported by a fast-rotating SR-60 search/track radar.

While the F22P CIWS fit provides some economy over that of e.g. the Type 054A, it has a less advanced supporting search track/radar. While the F22P still allows the ship to use both guns simulaneously (one using the eloppdirector, the other the radar director) there is some loss of flexibility. E.g. when operating under EMCON conditions, there is only 1 fire control channel for 2 guns than 2 if these where Type 730. Also, when dedecting sea skimmers, a radar director sometimes experiences the problem of multipathing: it sees the target just above water but also a reflection of the target via the water surface and can't decided which of the two to lock on to. One solution is the use of a secondary elop-director, which has no such problem and can help improve the system performance either by taking over, or by working together with the radar director.

OK does the both CIWS shoot same target at a time or it has ability to divide the targets like for example 2 core processors working together in multi-application environment?

It can work both ways i.e. direct both guns to engage the same target or a single gun to do the job and the other remain silent.

I suppose each director could lay a gun on a target, allowing the system to engage 2 different targets simultaneously. However, this capability is limited in that there may be some conditions under which the radar director will perform better than the elop director (or vice versa), in which case 1 director will be able to direct 1 or both guns onto only a single target. If you are going to put 2 guns on 1 target anyway, you would use both directors to track that target, but suffer some limitation in firing arc of the the 2 guns combined.

What is the update on the next Block of F-22P Block-II production that will have Stealth, Better weapons and improved performance in every way!!!

I am expecting that we will going to build 7 of these in coming years... Ameen.
PN should seriously think over making a Third Shypyard at KE&SWs along with the upgradation of the whole facility ASAP!!! Also GoP should take the whole charge of Gawadr port and make a GPA(Gawadr Port Authority) and utilize the experienced people of KPT and Port Qasim there to make it operational. PN along side many activities should look towards making a Proper n Advance Naval base along with the Three Proposed Mega Shypyard there.

Nice large pictures. Good-looking ship, in mint condition as well, kept by a professional crew. Great!

None ! Our largest ship is a 4000 tonne OHP frigate.

I assume this is a rhetorical question? Otherwise Google: Pakistan + Navy
