The C-705 air-launched anti-ship missile is the latest variant of the C-701 series, featuring a maximum range of 75km without the rocket-booster, or 170km when fitted with a rocket –booster. Using a GPS/inertial seeker, the missile carries a 110kg warhead and flies at an attitude of 12.15m above the sea level. The missile is designed to sink a small surface combatant of 1,000~1,500t displacement.

FAR - Forum Aviasi & militeR - C705 Anti Ship Missile

Original rocket engine of C-704 is replaced with a larger one, increasing the range to 75 km. Developers claimed that the modular design of the new engine had the option to provide a second stage to further increase the range to 170 km, but the second stage was not shown at the airshow.

Great news for the Pakistani navy, C-705 missiles are a superb choice and MRTP33 fast and stealth. It will add to firepower.

 

[MJaa]

This month, Yonca Onuk will begin integration of Chinese C-705 anti-ship Missile onboard Pakistani MRTP-33.

can anyone confirm this news that Pakistani MRTP-33 will be armed with Chinese C-705 anti-ship Missile and not the Harpoon-II anti-ship Missile

on an other note if PN wants to go for the Chinese option C-802A anti-ship Missile with 180 km range and more powerful warhead would make a lot more sense as it is already chosen for the F-22P and JF-17s

these are light patrol boats and might not be able to carry C-802/803..

Range of c-705 seems good .but it can only sink warship of 1000~1200 ton thats mean only effective against indian fast attack craft like vessel, if those comes close to pakistani coast . There destroyer and frigate will need special treatment .

for those we have other alternatives..
these boats are to sdafeguard the caost lines against terrosrist intrusions, smugglers and defence/offense against light weight boats..

C802
Weight 715 kg , Warhead 165kg
Length 6.392 m
Body Diameter 36 cm
Wingspan 1.22 m (unfolded); 0.72 m (folded)

RGM-84 Harpoon
Weight 1,523 lb (691 kg) with booster, Warhead 221 kg
Length Surface launched: 15 ft (4.6 m)
Body Diameter 1.1 ft (0.34 m)
Wingspan 3 ft (0.91 m) (unfolded)

I doubt very much that if these boats were capable of carrying 4 RGM-84 that they wouldn't be capable of carrying 4 C802.

Designated as C-705, the missile is a direct development of C-704, which is in turn an enlarged C-701

C701
Weight 100 kg, Warhead 29 kg
Length 2.507 m
Body Diameter 0.18 m
Wingspan 0.587 m (unfolded); 0.450 m (folded)

C704 has a 130 kg warhead, C705 has a a warhead of 110 kg. It is therefor likely smaller than or at best of equal size as C802

You don't have to sink a warship.
As long it is damaged enough, it will stay out of war. Depending on where the missile hits, like the bridge, rear, etc ship might lose vital functions.

What's this based on?

Exocet = 165 kg warhead
C705 = 110 kg warhead

Can Exocet sink only 1500-1800 tons and Harpoon only 2000-2400 tons?

See the differences between Exocet hits on 4800 tons HMS Sheffield (didn't explode but sunk her) and 6200 tons HMS Glamorgan (did explode but didn't sink her)

i think 1500-1800 tons figure for C705come from the manufacture

The ship caught fire when a French-made Exocet missile penetrated deep into HMS Sheffield's control room. The blaze caused a poisonous smoke and most of the crew abandoned ship.

The Exocet that struck HMS Sheffield impacted on the second deck, 2.4 metres (7 ft 10 in) above the waterline and penetrated deeply into Sheffield's control room,near to the forward engine room, cracking the hull open roughly 1.2 by 3 metres (3.9 by 9.8 ft). It appears that the warhead did not explode. Accounts suggest that the initial impact of the missile destroyed the ship's on-board electricity generating systems and fractured the water main, preventing the anti-fire mechanisms from operating and dooming the ship to be consumed by the fire. The loss of Sheffield was a shock to the British. wikipedia

This is from the Manufacture

MISSION MODULES

ONUK MRTP®33 can be equipped with various mission modules depending on the customer requirements. Despite the size of the platform, these modules have been integrated with the modularity and reconfigurability objectives in mind. Thus, the platform can be reconfigured with different mission modules, increasing dramatically the operational flexibility and reducing the costs. The mission modules would be:
Multi weapon mounts.
- Stabilized naval turret with up to 30 mm. gun
(+ short range SSM).
- Medium range SSM (Total weights up to 5 tons).
- Short range SAM.
- 2 x 12.7 mm. heavy MG.
Multi sensor surveillance unit
(EOD with capabilty of controlling the main gun).
Search and rescue equipment
Decoys
SOF (Special Operation Forces) support/SDV (Seal Delivery Vehicle)
Pollution control

as it is pointed out by other members combined weight of C-802 or Harpoon-II wont be lot different and in no way exceed 5 tonn

4x the missile weight + the weight of containers + the weight of the elevating module.

 

[MJaa]

4x the missile weight + the weight of containers + the weight of the elevating module.

4 C-802A (@715kg each )will make a total weight of missiles 2860kg and rest can be for weight of containers and elevating modules which i am sure will certainly weight lot less then that of missiles.

Chill, you don't have to convince me, given what I already said in post #53. Just pointing out what needs to be counted.

Nonetheless:

The standard stand-alone shipboard launcher for RGM-84 Harpoon is a quartet of Mk 140 lightweight (17,472 lb loaded ) or Mk 141 shock-hardened (27126 lb ) canisters. Ship typically carrying 2 sets.

That's 7,925 kg or 12,304kg, respectively according to the Naval Institute Guide to World Naval Weapon Systems (by Norman Friedman).

However, according to here:

A Mk 141 launcher assembly holds four missiles in shock hardened canisters at an angle of 35° and weighs 5,900 kg. In addition there is a smaller Mk 140 light weight launcher, either in four or two canister configurations.

Considering the different numbers, it could be that both are correct and that the difference (12304-5900=6404) is the weight of the metal structure on which one set of 4 missiles in canisters rests.

But this seems unlikely, also given the individual missile weights (4x 690kg = 2760 kg).

More likely is that the weight quoted by Norman Friendman is for a set of 2x4 rather than 1x4. If so, the Naval Institute Guide puts a 4-round Mk141 launcher assembly at 6152kg, which quite is close to the other quote for this assembly, namely 5900kg. That would mean the Mk140 assembly equals 50% of 7925 kg i.e. 3963kg, of which 2760kg (4x690kg) is actual missiles. (100*2760)/3963=70%

Applied to 4 C802 > 4x 715 = 2860 = 70% > 100%= 4107 kg at least for a lightweight assembly.

However, as we know, c802 canister assemblies on ships appears bulkier than those of RGM-84: there may not be a lightweight version.

Sticking then with the Mk141 assembly: 6152kg of which 2760kg is missiles (45%), when applied to c802 gives 2860=45% > 100%=6383kg, which would be too heavy for MRTP-33 (just like 6152 of Mk141 would be, incidentally).

But these numbers includes the metal frame on which the 4 canisters rest! Which may not be needed with MRTP-33. Question is whether the metal frames weigh more than 1152-1383kg ...
