Kalibr missile system

The other day, literally, information passed that the development of a new version of a cruise missile with a range of more than 4500 km Caliber-M was begun. A source in the defense industry told TASS about it. "For the Navy, the newest high-precision ship-based Kalibr-M cruise missile with a maximum firing range of more than 4.5 thousand km is being developed. The creation of the rocket is at the stage of research and is financed by the Ministry of Defense." The rocket is included in the state program of armaments for 2018–2027, and therefore, until 2027, it should be entered into service with the Russian Navy. It is also reported that the rocket will be larger and the mass of the warhead close to 1000 kg. New rocket is planned to equip large surface ships, starting with frigates, as well as nuclear submarines. As well as the progenitor of the new rocket will be able to carry both nuclear and conventional combat units, and will be designed to defeat ground objects.

I propose to start with dimensions: the Caliber 3M-14 rocket in its maximum configuration (let's say) has a caliber of 533 mm and a length of up to 8220 mm, and a mass of 2300 kg. In this case, it is considered that its range is 2000-2500 km. With a warhead weight of about 500 kg. Immediately make a reservation - the mass of a nuclear warhead can be significantly less - for example, 150 kg. The use of such missiles on shipboard ships is provided with a launcher of a vertical launch of the 3C-14 type. The same launchers 3C-14 are also used as the Onyx 3M-55 anti-ship missiles. TPK which has a length of up to 8900 mm and a diameter of up to 720 mm, the mass of the rocket is not less than 3000 kg.

It is not difficult to assume that the available reserves allow to carry out a rocket "type 3M-14" with a diameter of 700 mm instead of 533 mm and a length of 8900 mm instead of 8220 mm, which gives just at least 200 kg of additional fuel, but taking into account the optimization of the layout (I think that there are reserves, taking into account the age of the current missiles, will actually give more than 300 kg of additional fuel. And taking into account a more optimal aerodynamic shape, as well as more high-energy fuel, as well as updating the engine, it will fully provide a corresponding increase in flight range.

Yes, it is likely that the shape of the new missiles will be less round and more flat-square-diamond. The marching engine most likely will not move out of the hull. The start will be smaller in size. Perhaps in the new UBCS there is a reserve for larger-diameter missiles — then the task will be a bit simpler. By the way, with a modular design (and why not?) With such a nuclear missile, the range can be even more. Or maybe 4500 km - this is exactly the range with a nuclear charge? Then, in general, you can do almost nothing - learn how to put a rubber tank instead of half the combat compartment and fly. Just kidding, of course.
