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:
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:
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 ...
As per Jane's Naval Weapon Systems There are two launcher systems; the Mark 140 for fast attack craft and corvettes and the Mark 141 for larger warships. The Mark 141 features shock-resistant and thick-wall assemblies, which are usually used in larger vessels. Each has a support structure while the front ends of the launcher tubes are held by a clamp frame assembly. The central and rear ends are held by stacking frames with the thick wall assemblies providing armour protection for the missiles against fragments. The Mark 140 features aluminium launcher containers designed for 15 firing refurbishment cycles. These containers are held together and to the aluminium support structure by stacking frames. Both can launch missiles at the rate of one every 2 seconds but, with four launcher-containers, the Mark 140 weighs 4.02 tonnes while the Mark 141 weighs 5.9 tonnes. Usually ships carry a pair of launcher systems. The launcher-containers are inclined at an angle of 35º while the launcher systems either face forwards, but offset from the centreline, or are at 90º to the centreline facing starboard and port. The Mark 140 system is 4.65 m long, 1.38 m wide and 3.85 m high and requires 6.42 m2. However, with the development of indirect attack versions using `dog leg' flights (Block 1 C/D), the launchers can now face any direction. Normally launcher systems have four launcher-containers. The missiles were originally removed from the launcher-container annually for inspection but may now be left for four years with surface-launched weapons and five years for submarine-launched weapons.
Mark 140 Four launcher-containers weighs 4.02 tonnes with each harpoon weight is (with booster) 681.9 kg and C802A weights 715kgs so it is 1.05 times Heavier then Harpoon and if we use same percentage container should weight around 4.2 tonnes rest of the 0.8 tonnes is still there for any error in calculations
