Modernised T-72B3 main battle tanks to debut in Victory Day parade in Russia
Russia is expected to unveil its new version of T-72B3 main battle tanks fitted with new armour package at the Victory Day parade in Moscow for the first time on 9 May.
The new version of T-72B3 is fitted with armour plates on each side at the front of the hull and wire cage armour at the rear part to increase protection of the engine compartment against RPG (Rocket-Propelled Grenade) threats. The developers took into account the experience of fighting in Ukraine, Georgia and Syria.
According to the armour of the turret is also upgraded with a new armour package including new generation of ERA (Explosive Reactive Armour) mounted on each side of the turret, while the rear part of the turret is fitted with wire cage armour similar to the system used to protect the rear part of the hull.
Early, the T-72B3 has been deployed on operations on the Russia/Ukraine border where it has demonstrated a high level of survivability because it is fitted with the latest generation Kontakt-5 explosive reactive armour (ERA), which provides protection not only against missiles and rockets fitted with a high-explosive anti-tank (HEAT) warhead, but also kinetic energy projectiles.

Special Report:New High-Tech Russian Torpedo

A new superfast Russian torpedo may tip the scales decisively in underwater warfare.
A may tip the scales decisively in underwater warfare.
It is a successor to the 1970’s (Russian for ‘Squall’), which has an impressive speed of over 200 knots, far faster than any NATO torpedo, making it difficult to stop. However, it has range of less than ten miles compared to more than 30 for the US Mk 48. Shkval is also limited by the fact that it cannot use sonar guidance when travelling at speed. Western analysts have tended to be scathing about the Shkval, calling it a suicide weapon because of its short range. One Russian commentator described it as ‘.
However, a new Russian torpedo is likely to see the Shkval’s defects remedied. The Khishchnik ("Predator") is a new supercavitating torpedo at an advanced stage of development. Unlike various supposed superweapons which they boast about publicly, the Russians are keeping very quiet about Predator.
High-speed underwater projectiles rely on a principle called supercavitation. Rather than being streamlined, Shkval’s nose is blunt, ending in a flat disc. This creates a low-pressure area in its wake – the pressure is so low that a bubble of water vapor forms. This cavitation effect is well known; propellers are because it reduces contact with the water and causes damage. In supercavitation, the bubble is large enough to enclose the entire torpedo except for its steering fins. By travelling inside the bubble, the torpedo experiences far less drag than a normal torpedo in contact with the water. The low drag means it can reach phenomenal speeds.
Russia has long been the leader in supercavitating weapons. These include the bullets fired by the , effective at a range of thirty meters underwater – several times greater than any other firearm.
Torpedoes like Shkval use a more advanced version of the effect in which the cavity is ‘ventilated,’ sustained by an injection of exhaust gases. Shkval is not rocket-propelled as many sources assume; there’s a good description (in Russian) here. A rocket boosts the torpedo up to cavitation speed, but after that a hydrojet takes over, burning magnesium-based fuel and using seawater as the oxidizer.
Western efforts to copy Russian supercavitating technology have not so far been successful. There have been , but these have not translated into deployed hardware. DARPA had an ambitious plan for a 100 mph+ supercavitating submarine called the . They had a three-year contact with sub makers Electric Boat from 2006-2009, but it came to nothing. The US Navy RAMICS project involved b, the project ran from before funding was terminated without the system being fielded. The US Navy’s supercavitating torpedo project has been on hold since 2012; a spokesman says that improved understanding of the basic physics of supercavitation is needed.
The Western work may give us some insight into how the Russians are improving on Shkval. The reason why it cannot carry sonar is because the cavitating disc is much too small for a sonar system, and the engine is too noisy. General Dynamics . Rather than being flat, this is a parabolic curve, giving gives enough surface area for the sonar receiver. In the GD design the sonar emitters are mounted separately on the fin tips, and filters block out engine noise.
This suggests that a guided supercavitating torpedo is now feasible; a suggested that one was under development.
The other issue with the Shkval is its short range. Georgiy Savchenko of the at Ukraine’s National Academy of Sciences works on supercavitating designs and says that improved fuel will make a dramatic difference – he estimates that the range could be improved by a factor of ten.
Khishchnik may also be significantly faster than the 1970s Shkval. Very high speeds underwater are certainly possible. A US Navy lab succeeded in firing an underwater projectile , and the Chinese have , though there is no evidence they have achieved this.
Very little information is being released on Khishchnik apart from the fact that it is being developed by , a design bureau which makes instruments for ships and subs as well as aviation components. Its existence was revealed in documents uncovered by Russian defense blog BMPD which revealed that the company had been working on Khishchnik since 2013 and that launch tests were expected in 2016 as part of a contract worth 3 billion roubles ($53m). There have been no official comments or announcements.
Other companies may also be working on the project. In 2016, Boris Obnosov, CEO of Russian company Tactical Missiles Corp, to Rambler News Service
“Take for instance the well-known unique Shkval underwater missile. We are working on upgrading it heavily.”
The ‘heavily upgraded’ Shkval seems likely to be the Khishchnik.
Shkval has been upgraded several times previously, with improvements in range and guidance. A new name suggests a more significant upgrade. An , the Shkval-E was produced in 1999. There would be a big market for an unstoppable, carrier-killing torpedo.
