    Photos of Caesar in Ukraine : Tweet trad : What is surprising in this tweet is that they say that they used the gun at a range of only 22 km (and a previous tweet talked about a range of 20+ km). Either the Ukrainians know exactly what they are shooting at and put themselves just out of range, or they are not using the full range of the gun on purpose (either for greater accuracy or to prolong the live of the barrel by reducing the charge needed). DGA also gave more informations on the Caesar sent to Ukraine. Apparently only 6 were sent (for now?) when the initial rumours talked about 10 or 12. Contrary to what was initially suspected, those guns were not taken from the Moroccan order but directly from French army stock (leaving us with only 70 of them for now). It has been however confirmed that the software of the guns has been adapted in order to make it compatible with the Ukrainian artillery management system (meaning that they were being prepared for shipment long before it was announced by Macron). http://www.opex360.com/2022/05/28/le-delegue-general-pour-larmement-donne-des-precisions-sur-les-caesar-cedes-a-lukraine/

    Yes that was based on the price unitary price for the American M142, so the export price will indeed be higher. What I mean is that Poland have been buying or asking for a lot of hardware recently. Between the M1A2, 32 F-35, asking Germany if theoretically Polish T-72s sent to Ukraine could be replaced by Leo 2 at A6 or A7 standard, the K2PL being unlikely but still possibility, and as you said even more locally made MLRS and SPG. 500 MLRS (not even counting the locally made ones) for a country of roughly 40 millions inhabitant is gross overkill and it's hard to take that kind of announcement seriously. As I said, I understand that Poland find itself potentially at the frontline and that the invasion of Ukraine proved to a lot of Eastern European country that they were right to fear a Russian aggression. I also understand that most European army find themselves in the need to urgently plug some gaps in their armed forces. But the numbers and the variety of weapon systems that Poland is asking for or is trying to acquire is simply ludicrous. Logistics and maintenance cost will be ridiculously high, buying a system is all well and good and can be done by increasing the debt, but maintaining it in the long run will cost money as well. I'm not saying this to be rude but Poland, while far from being poor (8th biggest economy in Europe if you go by GDP), isn't the richest country around either. I genuinely don't see how Poland will fund so many different programs and purchases at the same time and more importantly how it will keep all of this equipment operational in the long run. Instead of buying a massive amount of weapons from abroad like a gulf Petro-monarchie, wouldn't Poland be better served by rationalizing it's armed forces (one type of MBT, one type of MLRS, etc) and strengthening it's local defence industry?

    Well MLRS (and artillery in general) have once again proved that they are key in modern warfare, so I expect everybody to strengthen their artillery forces. 500 of them though... that's at least €2.6 billions (just a rough estimate based on the unitary cost for the US). Where the hell will Poland find that money? The EU emergency fund will help but it's only €500 millions for 2023-2024 (to be divided amongst the 27). Then there is the EDF which is €8 billions for 2021-2027 but unlike emergency funds, it is only aimed toward collaborative long term European projects, not for off the shelf purchases. I'm probably forgetting other available funds (more will likely be made available anyway) and Poland can reasonably argue that they are now the first line of defense. But still, that would be a lot of money to dump in only one country (one that already receive a large share of EU funds in normal time).

    Story on how Russia needed to dig T-62 out of storage seems to be confirmed. T-62M spotted at Melitopol train station : Will probably either be used by occupation units or handed-over to separatists. Either way, it probably mean that there aren't many better machines left in storage and that they must keep them for the main forces. Which raise the question on how many tanks among the many thousands in storage are still in reasonable working order or can be refurbished. Regardless on the way this war will end, it seem that reconstituting Russian forces will be a tall order (especially without access to modern semi-conductors and other parts).
  6. Alzoc
    As far as I see it they are aiming for a moderate to no increase in penetration (keeping in mind the effective range of heavier vs faster rod discussion) while having an overall lighter and more compact turret+gun combo compared to the current generation. Thus the question of why do it for a 140 mm gun instead of keeping a 120 mm (same principles should apply)? That or I'm missing something or we are missing a piece of the info.

    MAMBA system (SAMP/T) at Capul Midia Romania : The system fire the Aster 30 missile with a range of up to 50 km (100 km against non manoeuvring targets). Guidance is provided by the Thales X-band Arabel radar up to 60-80km depending on the sources (and up to 120 km when focusing beams). One radar can control up to 4 launchers (8 missiles each). The primary role of the system is to serve as a semi-static defense for airbases against aircraft and missiles (including short range ballistic missiles).
  8. Alzoc
    Agreed, that is the core of the issue. As we both said we don't have the infos on the mass/velocity of both projectiles yet (though we can indeed speculate based on existing ammunitions). So we don't know if the distance where the energy of both round are equal will represent an interesting trade-off (around 2km) or if it will be completely irrelevant as you said (>4km). Yes I think that it surprised everyone when they announced an energy of "only" 10MJ at the beginning since it isn't much more (or even less in some cases) than modern 120 mm. The question whether the rod will be heavy enough to have a comparative advantage at some range against those fired from 120 and 130 mm guns is up in the air. Though lower chamber pressure will tend to increase the barrel life and/or lighten the gun (less thickness necessary) which is a nice plus.
  9. Alzoc
    No, both kinetic energy and friction forces are calculated using the squared velocity. So while it is much easier to increase the kinetic energy by increasing velocity, it also mean that for the same initial energy a faster projectile will bleed energy much much faster than a massive one : True the drag coefficient and the surface of the projectile play a part when calculating friction forces. While both will tend to be bigger for a bigger projectile they aren't the most important parameter. The main parameter for energy loss due to friction will always be the relative speed between the projectile and the fluid (air) : Note the section in bold, at high Reynolds (high velocity) the energy loss due to drag will even depends on the cube of the velocity. For a given initial energy there is always a distance where a heavier projectile will retain more energy than a faster one (unless you are in a vacuum and drag doesn't exist). The higher the velocity of the projectiles, the faster it is to reach that point. But we don't have enough info on the projectiles as of yet to tell at which distance the 140 mm will outperform the 130 mm (and whether or not the projectiles will ever reach said distance). As you said :
  10. Alzoc
    No but a higher velocity will mean a lot more energy loss by friction (be it in the tube or in the air during travel). Mass will stay the same during the whole flight while velocity will decrease quickly. Depending on the distance to the target, a slower heavier round can actually deliver more energy than a smaller faster one. There must be a set distance beyond which the 140 mm will outperform the 130 mm. Depending on the mass and velocity of both rounds it could be completely/mostly useless (like the 140 mm only becoming more interesting past 4 km) or a fair trade-off (cut-off range around 1 to 2 km). It is somewhat the same idea than 5,56 vs 7,62 mm for rifles past a certain range (assuming you can see the target). Beyond kinetics penetrators, there is also the payload to consider. A programmable 140 mm HE will pack more punch than a 130 mm one, especially if the 140 is fired at lower velocities.

    Nexter's Ascalon concept undergoing live fire trials at Alcochete (Portugal) : Sadly, no public images available yet. Ascalon is a 140 mm gun using telescoped ammunition (meaning potentially longer APFSDS rods and more ammunitions onboard) and is the main competitor of Rheinmetal's 130 mm for the MGCS. The energy at the muzzle, is not overly impressive at 10MJ (with a goal of 13MJ by 2025) compared to the 9-12MJ of current 120mm but Nexter claim to reach those energy at a lower chamber pressure than current guns. So we have two concepts going in opposite directions. Rheinmetal's 130mm will have a much higher muzzle energy than the current generation of guns (50% more according to Rheinmetal) which mean that the platform using it will have to be sturdy enough to withstand the recoil, while Nexter is going toward a lower energy gun (compensated by longer kinetic penetrators) which could theoretically be mounted on lighter platforms. That might show opposite visions for the MGCS which lines up somewhat with the operational culture of both country. A heavier tank geared more toward territorial defense for Germany, and a lighter more deployable platform for France. The 130 mm is also using mature and proven technological solutions, while a 140 mm CTA is (as far as I know) something new which may lead to hurdles during the development process. So the maturity of the technology (which will be somewhat linked to the cost) will also be a factor.

    French army is apparently also changing it's infantry camo (delivery in 2024) with an (almost) omni-environment pattern. Base camo will be used for woodland/grass/urban/desert/mountain and a variant of the same pattern will be used for an all snow environment. Apparently they focused a lot on how a change in lightning will modify how the eye perceive the pattern : Same base color as the new Scorpion camo for the vehicles with the possibility to add active camo on top of it in the future (for infantry that may be a bit optimistic) : Seems everybody is going toward an unique camouflage pattern.

    General Atomics is proposing a kit for transform it's MQ-9B into STOL aircraft capable of operating from a LHD. https://www.ga-asi.com/ga-asi-grows-mojave-line-with-new-mq-9b-stol-package Remain to see the minimum length of the flight deck necessary for the drone to take off and land as well as it's width (the MQ-9 has a wingspan of 20m).

    Cutaway of the future MAST-F (future air to ground tactical missile) which should equip the (French) Tiger MkIII (and maybe the Eurodrone) : The MAST-F will be a derivative from the MMP with a range of 8km and will replace the Hellfire II while being 20% lighter (extending the operational time/range of the Tiger). The helicopter will be able to carry up to 8 missiles. For now only France is slated to use this missile (since Germany didn't joined the Tiger MkIII program for now and Spain is using the Spike as it's main ATGM). https://www.forcesoperations.com/du-neuf-sur-le-programme-mast-f/

    I think it's more down to the economical zone that come with it once the war end. If I remember correctly there is some gas reserve exploitable in the sea around. For military interest it can only serve as a radar station for the Russian to monitor Ukrainian air traffic, and the same (plus serve as a potential platform to launch anti-ship missiles) for the Ukrainian. For both side, staying there require a beefy anti-air cover which make it probably not worth it. My guess is that both side will make sure that the other doesn't settle there and try to occupy the area just before the end of the war. in order to claim the resources that goes with it.

    Well I understand that they didn't popped up earlier since the Ukrainian didn't want to engage in an open fight with the Russian army, so they kept their armoured forces mostly hidden. But as you said, it is weird that they appear isolated . If the Ukrainian engaged in counter attack they would want their armor to be concentrated... Unless they use them as armored recon before entering a village that used to be occupied by the Russian. The tank has more chance to survive an ambush than anything else and that would explain why they only send them one at a time (with infantry backup if they aren't stupid).

    They will already be running two different types of MBT (plus the T-72s in reseve) soon enough anyway. That is already madness enough. At least with the Leopard 2 they have the German industry right at the border for logistical support if needed. With the M1 they'll have to create all the logistical support that goes with it (plus maybe have to deal with some shenanigans with imperials units...). They may be able to rely on existing US army infrastructure in Europe for a while but they'll have to create their own at some point, and that will probably cost them an arm. The biggest problem will probably be the M1's weight (especially if they are taking the latest version), a lot of their infrastructures probably can't handle it and there is also the question of whether they'll have to replace their bridging equipment (there are a lot of rivers in Poland). It's definitively a capable MBT but switching the logistics will be a nightmare and will be insanely expensive. I understand that it is mainly a political purchase to have a guarantee against Russia, but IMO they should have stuck with their Leopard 2 (maybe keep modernizing them) and replace all of their MBTs at once in the future (K2 PL or any indigenous design) to keep only one type of MBT in service.
