There is a rather large piece of the puzzle missing. Iran’s confidence does not seem to match its capabilities. They must have 'something'. In search of that something, could be the 'Onyx'.
I would venture that the Chinese have the ‘Onyx’, Iran has the ‘Sunburn’ maybe the super ‘Sunburn’ or Onyx.
IRAN: Possessing excellent defense capability Army Marine Force Navy commander Abbas Mohtaj said here Friday, the marine force is ready to protect the sea borders of the Islamic Republic of Iran. #msg-3379634
CHINA: China is focusing on building up a more advanced submarine fleet with quieter vessels and harder-to-detect torpedoes, a key component in holding back any US naval task force were the US to intervene in a cross-straits war.
The above sentence gives us a glimpse at one of the weapons of the ‘assassin’s mace’, the new advanced submarines. The ‘mace’ includes a prevention of intervention by superior US forces that are ferried throughout the world on carriers. What China is saying is that should a conflict arise we will see one or more of our aircraft carriers and accompanying ships disappear.
The U.S. Navy is confronting a new danger – the growing fleets of quiet, diesel-electric subs among potential enemy nations and China has indicated they will use them. #msg-3333316
Both China and Iran have the new difficult to detect subs. The ‘Sunburn’ has been adapted by Russia for submerged launch from submarines. #msg-3379438
The ‘Onyx’ it seems has also been adapted for submerged launch from submarines.
Having already stalled Israeli and American pre-emptive nuclear strikes by deploying the much-feared SS-N-22 Sunburn missiles to Syria. Iran and China, the Kremlin decided to turn the military wick up the same week as the Yukos debacle, by discreetly leaking a report showing the devastating Sunburns would be progressively replaced in 2004 by the even more devastating SS-N-25 “Onyx”. Though at first glance it might seem impossible for the Russians to improve on the unstoppable Sunburn, they have managed to do so, thus ensuring absolute Russian and Chinese supremacy in the Eastern Hemisphere for at least the next two decades.
Though Sunburn can fly 150 kilometers at Mach 2.1 [1,520 mph] at an average altitude of 60 feet, Onyx leaves this performance for dead. Using the same launch tubes as Sunburn, Onyx streaks along its extended 200+ kilometer flight path at a blistering Mach 2.9 [2,100 mph], while hugging the ground even closer at an average altitude of only 45 feet. Onyx is 100% “Fire and Forget”, meaning that once out of the launch tube, flight management is entirely automatic, and you can forget the doomed 93,000-ton aircraft carrier sitting meekly down range, only minutes away from being converted into environmentally-friendly heat and light.
Though SS-N-25 deployment might seem like giant overkill, this is far from being the case, because Onyx differs from Sunburn in one utterly crucial way. So great is the kinetic energy at the point of impact on the target, that Onyx can sink an American aircraft carrier using only a conventional penetrating warhead. Those boffins who might doubt this should calculate the impact energy of 5,500 pounds of missile striking a carrier at a terminal velocity of 2,460 feet per second. Onyx means that Russia or China can sink American aircraft carriers at will without ever having to escalate to nuclear warfare, which gives both countries a massive strategic advantage.
