American scientists have developed a quantum inertial unit allowing navigation without GPS

In the early 90s, the arrival of satellite geolocation, and in particular the American GPS system, profoundly changed the design of defense equipment and the conduct of operations. Rapidly, the GPS became a major element both for navigating and for designing precision weapons, the system becoming one of the pillars of American and then Western technological superiority, particularly in the context of medium and low intensity conflicts in which Western armies were engaged. Over the following years, other systems, such as the Russian GLONASS, Chinese Beidu or European Galileo appeared, increasing the dependence of the armies of the world on…

US Air Force tests new 5000-pound GBU-72 bunker bomb

Most often, when talking about bunker busters, reference is made to the famous GBU-43/B Massive Ordnance Air Blast Bomb of 22.000 pounds, sometimes called MOAB for Mother of All Bomb, and made famous for their use against cave networks in Afghanistan, as well as the 57-pound GBU-30.000A/B Massive Ordnance Penetrator designed to equip the B-2 bombers. But these munitions are both very expensive to build and complex to implement, the MOAB being able, for example, to be dropped only from a C-130 transport plane. While the risks of having to intervene against strongly defended targets continue...

Are aircraft carriers now too vulnerable to be useful?

Since the announcement of the launch of the French New Generation Aircraft Carrier program by the President of the Republic, many voices have been raised to question the relevance of such an investment, particularly in the face of the threat represented by, now, long-range hypersonic anti-ship missiles, such as the Russian 3M22 Tzirkon, or the Chinese DF26. According to them, and according to others, particularly in the United States, such behemoths of the seas are easily located, and therefore constitute prime targets for new enemy anti-ship missiles. However, a factual and objective analysis of the capabilities offered by aircraft carriers, as well as the reality of…

Rafale: flight tests of the new 1000 kg AASM ammunition have started

A few months ago, we presented to you in detail the new F4 standard of the French Rafale fighter, produced by Dassault Aviation. In addition to notable improvements in sensors, connectivity and logistics, the Rafale F4 was also to incorporate new air-to-air and air-to-ground armaments. If the MICA-NG and the renovated SCALP are based on known armaments, the 1000 kg AASM developed by Safran is indeed a completely new ammunition. For some years now, models of the AASM-1000 have been exhibited at various air shows and exhibitions. Since the launch of the F4 program in January 2019, however, we were…

The "British GPS" will probably never see the light of day

In 2018, when the announcement of the United Kingdom's eviction from the Galileo program because of Brexit, the strong reactions emanating from the political class and the British government had finally convinced Theresa May to brandish the threat of erecting a system of national and independent geo-positioning of the European initiative. A feasibility study and £130m later, the symbol of post-Brexit independence is unmistakably suffering from ignition delay. Disagreements between British ministers and senior civil servants are now emerging as to the viability of an expensive but no less strategic project in a particularly degraded international context. In fact, according to an article…

Iranian missile accuracy would rely on Russian GLONASS system

The precision of the Iranian strikes on the Iraqi bases on January 8 surprised many specialists in the military question. According to the Israeli site DebkaFile.com, which specializes in intelligence and geopolitical issues, this precision was obtained thanks to the Russian geolocation system GLONASS, equivalent to the American GPS system. Indeed, according to several Russian sites quoting military sources, Tehran would have integrated this geolocation system into its ballistic missiles, giving them an accuracy of around 10 meters, which corresponds to the observations made on the satellite photos following the attack. . For now, both American and Israeli intelligence services cannot…

The cyber security of Western satellites could be compromised

According to a report by the highly reputable British Think Tank Chatham House, satellites used for defense purposes by Western nations should all be considered as potentially compromised in the planning of weapons systems and technologies employing these systems. A complementary report also points out the vulnerabilities of Western missile systems, whether strategic, anti-aircraft defense or tactical. In these reports, the Think tank draws up an uncompromising assessment of the weaknesses in cyber warfare that characterize the use of satellite communication and location systems which, very often, have mixed civilian and military vocations, so...

The Multiple Tornado-S rocket launcher equips a first Russian brigade

Heir to the Red Army, the Russian army has retained a certain appetite for artillery systems. Not only does it have many more than its Western counterparts, with a mobile artillery system for 120 men, one for 500 on average in NATO, but also does it develop many systems so as to maintain a permanent advantage over potential opponents. And today, it has advantages. Not only does its self-propelled guns fire farther and more accurately than the majority of Western systems, but it also employs a large number of multiple rocket launchers, with remarkable performance. The 9M542 Tornado-S system fits perfectly into this…

The hypersonic missile Zirkon tested this year from a frigate

According to the official Russian Tass news agency, the new frigate Admiral Gorshkov of project 22350, will carry out the first naval launch of the new hypersonic missile Zirkon this year, thus confirming that the new missile can be implemented from the vertical silos intended for the Kalibr naval cruise missile or the P800 Onyx anti-ship missile. The new missile, capable of reaching Mach 9 for a range of over 1000 km, should enter service in the early years of the 2020s, and will equip offshore surface vessels such as the Gorchkov and Grigorovich frigate, or the Lider destroyers. , that the corvettes equipped to carry…

The return to favor of the naval artillery

Since the beginning of the 90s, and the advent of precision-guided missiles, naval artillery had gradually lost its predominance in the design of combat ships. The number of rooms had already been reduced in previous years to their minimum portions, it was then the turn of the power of the rooms to decrease. While 5-inch (127 mm) pieces were the reference standard of the 80s, we saw the appearance of smaller calibers, such as 3-inch (76mm), and even 2-inch (57mm), on major surface combat units. In France, the…
