Russia’s Defense Ministry is currently in talks with aircraft makers to discuss the development of a promising vertical take-off and landing (VTOL) plane for a future aircraft carrier, Russian Deputy Defense Minister Yuri Borisov said.

The fighter jet will derive from a group of vertical take-off and landing planes manufactured by the Yakovlev Company, he added.

JSC Region State Research and Production Enterprise, part of the Tactical Missiles Corporation (TMC), has developed a new APR-3ME Grif airborne anti-submarine missile, which is a modernized version of the APR-3E missile. The new system was unveiled at the MAKS 2017 airshow currently held in Russia.

Japan to Produce and Procure XASM-3 Supersonic Anti-Ship Missile in 2018

quote:

According to Japanese news site Yomiuri Online, Japan's next geenration XASM-3 supersonic anti-ship missile will enter mass production in 2018. The missile will also be officially introduced with the Japan Air Self-Defense Force (JASDF), it will then be called ASM-3. The Japanese MoD likely conducted a test earlier this year as we previously reported.

Strategists contemplating Asia-Pacific strategy quickly come to the conclusion that the undersea campaign is decisive. Fixed targets are vulnerable in the age of precision strike, meaning that air bases do not have a chance against a barrage of missiles. And with advances in ISR (Intelligence, surveillance and reconnaissance) sensors and ever expanding missile ranges and power projection platforms, surface warships may not fare much better. Thus, it is no laughing matter to consider rumors that China has pulled off some breakthroughs in submarine quieting or that the PLA Navy submarine force has ambitions to enter both the Arctic and also the Atlantic as part of a much enhanced pattern of operational deployments.

But undersea warfare is not static and some have speculated that higher computer processing speeds combined with myriad new underwater sensors could render even remote parts of the ocean more and more transparent, undermining submarine stealth and survivability. Some of China’s recent achievements in these developments have been noted in this space. Another question hovering over the undersea warfare planner is the question of how important undersea robots, both unmanned undersea vehicles (UUVs) and remotely operated vehicles (ROVs) could be. Will they come to assume the same vital role that unmanned aerial vehicles (UAVs) have assumed? A Dragon Eye column has dipped a toe into this discussion before by examining the role that the new U.S. Navy anti-submarine unmanned surface ship (USV) Sea Hunter (with an extraordinary range of 10,000 miles) could play in the evolving U.S.-China maritime rivalry. This column will dip another toe into this pond and explore several Chinese platforms in development of this nascent unmanned contest unfolding on and under the waves.

Depending on Erdogan's mood, that could be the worst mistake Russia made in a while. Of course, it's more likely that a "crippled" system will be going to Turkey.

Unlike its older DF-31A , which is placed on a semi-trailer 1S1-31A , which is pulled by a road tractor, this new DF-31AG uses a 16 × 16 Tractor-Erector-Launcher (TEL) Thus its off-road capability.

The launch tube has several circular reinforcements, suggesting more pressure during missile take-off. Changes in the propulsion system, at least for the 1st stage, could have been implemented. It is therefore not excluded that a new type of propellant of the N-15 family, which develops a specific pulse (ISP) higher than that of HPTB and NEPE used in the other ICBMs of the world.

It is probably for this reason that this new variant of Chinese mobile ICBM is called DF-31AG, which should read DF-31A (改), where 改 (Gaï) means "Modified" in Chinese.

While the propulsion system of the missile seems to have evolved, there is no indication that its size has changed. The DF-31 and its extended range version DF-31A are mono-ogive ICBMs, the first and second stage of which measure 2 meters in diameter and 1.4 meters for the third stage. The maximum effective range of DF-31A is 12,500 km.

[...]

Based on the first available elements today, it is believed that the DF-31AG would bring the following gains over previous versions:

-Improve the off-road capability of the carrier, therefore its mobility and survivability
-Increase the range of the missile at a lower cost, by changing its engines and reducing the structural mass

Therefore, the DF-31AG would be a project to upgrade the existing DF-31 and DF-31A to a more advanced standard without fundamentally changing the design. It is unclear, however, whether it is the DF-31B whose existence was revealed by the Americans after its shooting of September 25, 2014 .

To be continued.
