Austin wrote:What we know from missile designer interview is they dont use post Boost vehical and that its warhead is independently propelled and guided ......we do not know what kind of propulsion if its uses normal fuel or something exotic.

Its still a mystery what RS-26 is although all indicating are its a lighter missile that needs 80 T vehical compared to RS-24 120 Ton

Unless a very high specific impulse (Isp) and structurally mass-efficient propulsion system was being used for each reentry vehicle (RV), replacing the third stage, the PBV, and the RVs with independently propelled RVs would technically have very little (i.e. almost no) advantage and a lot of disadvantages. That is the Isp and mass-efficiency requirements have to be so high as to offset the “penalty” of the configuration just described. The easiest way for the Russians to achieve the required level of Isp and mass-efficiency is through the use of a scramjet or a ramjet. The option of using a subsonic combustion ramjet is not viable due to the Russian speed requirements and one other technical consideration; so the “easiest” option available for them would be to use scramjets.

Of course, this hypothetical system would really be an air-augmented ICBM, like for example the ancient Russian Gnom system. As such this system would even be more efficient than a rocket-only system, and would allow a substantial reduction of the system mass for a given level of performance.

Coming back to Scramjet , If Scramjet propulsion is used it would need air to burn in and in space you cant get scramjet to burn as there will be no fuel for it to burn , technicall you can burn a scramjet at 90 -100 km.

i have a question. Whats the purpose of the development of a nuclear missile of that range since the target can be reached with the greater range ICBMs that Russia has??

1. Re-launch of a "SS-20 standard missile " as a part of a bid for global power on the part of Russia and send a message to the West that goes us back to where Cold War ended when INF Treaty was signed (1987) ?

2. Part of an attempt of Russian military to develop a more sophisticated nuclear strategy that do not call for an all out nuclear first strike in case of nuclear war, by giving them a second strike capability?

3. Or just Russian government want to promote the interests of the military-industrial complex by ordering various types of missiles?

The new missile system RS-26 will go on combat duty in 2016

Garry, quick question. On what basis will they determine the "test range" of the RS-26? Obviously it is not going to fly for 10,000 miles during the tests.

Moscow. March 26th. Interfax-AVN - intercontinental ballistic missile RS-26 "Frontier", developed in Russia, does not violate the requirements of the START-3 and Intermediate-Range Nuclear Forces Treaty (INF), said, "Interfax-AVN" on Thursday in the Russian Defense Ministry .

"Americans have no official claims to the missile RS-26 will be charged. Because of these claims have no grounds. The American side was presented telemetry test launches RS-26, which clearly proves that the new missile belongs to the class of intercontinental ballistic and does not violate the agreement START -3 and INF - a spokesman said.

He was commenting on the publication in the newspaper "Kommersant" that in Russia successfully completed state tests MS-26, which may soon enter the Strategic Missile Forces, and that the US considers this a violation of START and INF.

According to him, work on the PC-26, which differs from the missile RS-24 fewer steps and a reduced range of start-up, is one of reciprocal steps Russia to deploy US global missile defense system.

"We have repeatedly warned the US" counter-partners "that new US missile defense bases in Poland, Romania and other European countries will not go unanswered," - a spokesman said.

He explained that at the start of missile RS-26 "Frontier", for example, from the interior of Russia, it becomes virtually invulnerable to any prospective US missile defense due to the small time steps of the active site of work.

Earlier, former Chief of General Staff Strategic Missile Forces, Colonel-General Viktor Esin said "IF-AVN" that Russia promptly notify American partners under the START-3 to work on the modernization of intercontinental missile RS-24 variant, called the RS-26.

"Moreover, it was demonstrated launch MS-26 from the Plesetsk cosmodrome at the Kura test site in Kamchatka at a distance of more than 6 thousand. 300 kilometers," - said V.Esin who participated in the preparation of the START-3.

Thus, he said, the start-up performance confirms that the PC-26 is not subject to the restrictions on the range set by INF Treaty, prohibiting the United States and the Russian Federation to produce, test and deploy ballistic and cruise missiles, ground-based medium (from 1000 to 5500 km) is lower (from 500 to 1000 km) range.
V.Esin recalled that the START-3 will allow the United States and Russia to modernize its intercontinental ballistic carriers. "And the Americans use it fully upgrading its" Minutemen "- V.Esin.

He noted that the exercise with Plesetsk launch of the RS-26 shows that "no doubt about intercontinental missiles this class can not be."

The expert also pointed out that Russia, as required by the START-3, notifies its American partners on activities in the field of modernization of strategic weapons and conducted launches of intercontinental ballistic missiles.
