The M1E3: What has the Army actually said?

I dig into the press release and make some observations on what the release says, what it doesn't say, and more importantly, some food for thought as to the possibilities which exist with the new development type.

As a guy who works with that stuff, it might be better to go with copper. Yes, fiber is lighter and you get more throughput but copper is way more robust and we're talking about a tank, not an F-22 Raptor. But who knows.

The M1A1 AIMS was not the predecessor to the M1A2. I participated in the M1A2 IOTE Test in 1991 at Fort Hunter Liggett. The AIM tank came out around 2005 as much of the Army hadn't gotten the M1A2 let alone the SEP version yet. I believe the AIM version was just a stop gap measure. Like the M60A3 was before all units transitioned to the M1. I think Fort Hood was all SEP v1 by the time many units were getting the AIM tank or maybe we at Fort Riley were just that far behind 🤣.

[@TheChieftainsHatch]

You are correct in terms that AIMS was not a successor vehicle, (I received mine off the production line in about 2007) but I don't believe that the underlying A2 technology is any different. I focused on AIMS because I am certain about it

[@shannonkohl68]

As to electronics vs. hydraulics, I believe that SpaceX switched from hydraulics to electronics for engine gimbaling. Which presumably requires a lot of force and accuracy. So probably another indication that the M-1 would do just fine with the electric controlled turret.

[@trioptimum9027]

I very much suspect you're right and the electrics will be totally fine, but there are important differences as well. Failure is quite a different scenario, after all: -I think the engines gimbal independently? So if you lose gimbals on one engine, you can compensate with the others pretty easily. If you have the choice between nine engines with nine gimballing systems each of which is 99.2% reliable, versus a heavier system that is 99.5% reliable, and you can fly just fine with seven out of nine gimbals working... You'd probably pick the lighter one, y'know? (Play with the numbers until you get a number of nines acceptable for crewed flight, of course). But if it's a single point of failure instead of a "we can lose three, no problem, but four might cost us some missions and losing six could kill someone," the math changes, right? -The consequences of partial failure are different. A slow or off-calibration gimbal on some engines while others are working fine probably means you can't use those gimbals. A slow or off-calibration turret rotation system is still very much better than no power traverse. So if the electrics are more likely to die all at once, while the hydraulics are more likely to start to fail a little at a time, that might be worth a little more weight even though the top-line "reliability" statistic is similar.

[@uku4171]

And the electric actuators seem far better in terms of functionality. Don't know about reliability, but I doubt it's bad. Also, do you know if the flaps use electric or hydraulic actuators?

[@filmandfirearms]

@@alexisXcore93 Not really, it's a pretty standard concept. The problem is always in actually implementing it. By their nature, you rarely end up replacing your light and heavy vehicles at the same time, so the likelihood of the engine being relevant for both when needed is pretty low. Italy is a small enough country that they can do it, but major nations can't. For example, the BMP has been using the same engine since its introduction. It's good enough, and there hasn't been reason to significantly change the chassis, so why change it? In that time, Russia has also changed their MBT several times over, even trying a turbine in the T-80. A T-62 engine in a T-90 or T-80 simply wouldn't do

[@DefinitelyNotEmma]

I think the M1 (or any current MBT) has still a lot of potential for future development. The basic template offers a lot to work with, by installing new subsystems, engines, maintenence friendlier options. Point being, and I could be wrong, an empty hull stuffed with brand new, maintenence friendly systems and possibly a new turret is a promising prospect for the future. Not to mention that the tank isn't just meant to fight opposing armor. It's also meant to break through defenses and provide long range, heavy fire power where it's breakthrough capabilties are needed. And something like that doesn't require a totally new tank developed from scratch, especially given how most adversaries also spend more time and money improving existing stocks rather than developing or procuring brand new systems.

[@lostalone9320]

You're right - When there is no pressing need for big change, nothing even close to a paradigm shift, then you really just want to make what you have easier, cheaper and less of a pain. Nothing wrong with that.

[@DefinitelyNotEmma]

@@lostalone9320 I think cheaper and more logistically sound are the keywords. If we're looking towards Ukraine, tank losses are immense. And that wouldn't be different with large numbers of M1s. And while the US themselves would lose less, due to different doctrine, training and logistics. It still means an emphasis should be put on the ability to easier replace components and entire tanks. Improved logistics mean that a damaged tank can be put faster back on the frontline. And I think that's much more important than a 140/130mm, heavy armor packages and even more weight which hampers logistical support. That's actually why I like the T-90 a lot. You can load lots of them onto a train, maybe two without additional armor on an An-124 and they can be produced comparatively quickly. Ideally something like a T-90M with a bustle autoloader (and blowout panels), a fuel efficient engine and shared component with other systems would be made. Something easy to produce, low profile, mobile, with a lot of parts commonality.

[@capt5656]

@@lostalone9320 The problem is, as i think the chieftain himself mentioned (or maybe someone else, don't quote me), New systems are starting to put a huge burden on these cold war designs. The thing is, you are never working with an empty hull when upgrading these designs, so adding all of these new electronic equipment and sensors, and things like active protection systems become far harder to do. And while i know the reformers are out there waiting to rag on fancy new tech, the modern battlefield has shown that lethality is increasing and MBTs need to keep pace, at least until something that can perform its role comes to replace it.

[@MyWaifuNow]

Its a 30+ year old design that's been added onto with SEPv1-4 and now weighs too much. Germany has the Panther KF51 which is a 60 ton tank with a 130mm cannon and seemingly more turret protection than the Abrams. The turret is probably the biggest problem as it's not very sloped by modern standards meaning it needs thicker armor and more weight to achieve the same protection as other tanks and the armament is likely falling behind. If they upgrade to a 130mm cannon the loader has less space and it can carry less ammo total and if they upgrade the turret face at the same time how heavy does it become? Does this 80 ton tank become 100 tons to match the firepower and armor of a 60 ton KF51? Sure they could rip out the internals like you said but that probably cant save them enough weight to allow armor and weapon upgrades matching other modern vehicles especially with the slightly dated turret face.

[@Azylath]

Germany isn’t going for the KF-51, they have their own design they’re working on with the French. The KF-51 is entirely a private venture by Rheinmetall. Also, that turret isn’t sloped “by modern standards”. That’s just an evolution of the arrowhead add-on armor of the Leopard 2A5+. The base armor is what’s composite snd on the Leopard 2s isn’t even sloped.

For decades, the Army just couldn't find a "new" tank that really was more cost-effective than sticking upgraded modules in the M60. We went through several promising vehicles that came close to replacing M60 before M1 finally was adopted, but every one was too complicated, unreliable, expensive, or otherwise unsuitable compared to M60. Seems like we are in the same situation now with M1. Every time someone says "we really need a new tank entirely that efficiently integrates all the technologies we have and want," someone points out that it is just cheaper and easier to put a better computer or whatever on/in M1.

You took the lebel, throw it away except the front band and a couple of bits, add the bits to the RCS and, presto, here is a cheap, upgraded rifle way more economical than a brand new rifle. This M1E1 sounds more or less the same: it keep maybe the hull-thub and the return rollers (or the greasepump track tensioning, much to Chieftain disdain), everything else is something new. But is just a budget-reasonable upgrade, not a totally new tank program, in the PR leaflet.

[@ARCNA442]

"E" is used for experimental modifications, not fielded equipment. If the M1E3 is accepted, it will become the M1A3. The SEP variants are considered upgrade packages for the M1A2 rather than modifications to the base tank.

[@hegoyyoutubination]

because this denotes the vehicle itself and upgrades it has been though. The same way as: M60 (vehicle) A3 (modification) TTS (upgrade package) M2 (vehicle) A2 (modification) ODS SA (upgrade package) M60 (vehicle) A1 (modification) RISE (upgrade package) M109 (vehicle) A6 (modification) PIM (upgrade package) etc.

[@barrag3463]

'E' used in that way means some kind of modification to the hull that is a change to the hull that is big enough to make it different but not big enough to justify being a different production model (the 'A'). The SEPs are upgrade packages that are addons- they can (and probably are) put on or taken off as needed, but either way the M1A2 under is the same as an M1A2 without it. We're probably not going to see another M#A#E# something because doing modifications like that is at best a bit confusing for logistics. As far as I know the only times we did that was during WWII and the Korean Tank Scare because we were willing to put up with logistics hiccups if it meant we could have more factory lines producing more tanks, even if they had differences (and even then not every difference justified a different designation).

[@CobraDBlade]

While I'm sure they've thought about it already, I'm wondering why if they are looking at service past 2040 and are already looking at the cost of retooling production for significantly redesigned components, are they not looking into a clean-sheet design that puts forth everything we have learned about MBT design and expected capability? Surely a design from the 2020s would be more relevant on the 2050 battlefield than a remake of a design from the 1970s?

[@andrewreynolds4949]

My guess is this prospective M1A3 is a middle ground between a short term, less expensive SEP v4 package and a long term, much more expensive totally new platform. The Abrams hull is still solid, so as long as everything can still fit inside (and there aren’t any signs yet that it can’t, as long as the internal systems are replaced as he describes) there’s not much advantage in designing a new hull, with the time and cost that would require. Even if they replace the turret with something completely new most of the hull will still be pretty much the same

[@nemisous83]

AbramsX honestly seems like the most logical choice however the Army needs to decide if they want to go to a fully unmanned turret or a manned turret. The former seems more sensible since it would reduce the most weight. Also more weight could be shaved off if they replace the interior of the turret which is optionally manned with more systems or delete it entirely and save more weight.

[@anonymous-ml8sl]

Keep in mind AbramsX was a technology demonstrator so whatever the army gets would likely look drastically different. AbramsX was essentially “hey look what we can do if you anted us to”. As for unmanned turrets, from someone who has talked to German soldiers, and 2CR guys with dragoons I’ve heard nothing but hate for them, the ability to have direct access to the gun and the tc to be able to pop his head out and look around from what I’ve heard outweighs the advantages. This is all conjecture but I personally believe we will see something with an auto loader, as robotics have sky rocketed in the past 5 years in capability.

[@grgr105]

@@anonymous-ml8sl The thing with unmannned turrets and the crew comforts was already known before they were adopted in the various militaries. The goal of unmanned turrets is to make the vehicle safer, something which soldiers in general service generally don't notice, as they aren't shot at with HEAT shells that impact their turret. The fact that with unmanned turrets you can completely isolate the crew from anything explosive is incredible, if you care about the lives of your soldiers. And I as a German generally have heard nice things about the Puma. The soldiers may often complain about it, but the complaints I hear are less about the unmanned turret and more general vehicle design. Complaints I hear are mostly about the small turret magazine (you need to reload after 200 30mm rounds), overengineering and over-complication, plus bad training about how to repair the vehicles.

[@nemisous83]

@@anonymous-ml8sl well autoloaders have never really been complex it's just a simple ramming arm however the MGS made it needlessly complex. Having access to the gun is largely unnecessary because if there was an issue that required the crew to open up the autoloader in combat it's more likely they would simply break contact and RTB for repairs than waste time trying to manually load the gun. However the main reason the commander would want to stick his head out of his hatch is to guide the driver but AbramsX has a back up camera so the crew has full situational awareness. Both M1 TTB and T-14 were well received by their test crews and there isn't any mention of the commander feeling he was blind or didn't have good vision. But people have been debating this for decades with things like gunners auxiliary sights which most modern designs of the 21st century have since deleted.

[@centurion1945]

​@@nemisous83there's a lot more in terms of situational awareness you get from having the TC with their head out the turrent, than just easier reversing. Having full use of your peripheral vision, as well you're other senses (sound, smell, feel do in fact subtly inform a TC's awareness of the surroundings) there's a reason why a TC today is very rarely fully "buttoned up" in the turret, they'll have their head out the hatch more often than not. I would he very surprised if the Army goes for an unmanned turret. Going to an autoloader and 3 man crew seems more likely, although that would also necessitate larger changes in a tank units MTOE, as the Army also currently seems to regard 4 crewmen to be the minimum for reliable field maintenance and watch, plus many tanks will at times be a crew man down due to illness, injury, leave, training needs, etc. Chieftain has been a big advocate for mirroring French armor formations which attach full time dismounts riding in trucks to the formation, who aid in repair, keeping watch, and other field duties.

If they want something simple and easy to work on, thats actually not too hard. its usually when they also want cutting edge technology and have a complicated decision making apparatus or regulations to comply with that things can go sideways. But you also see successes by various companies as well, and usually these have engineering teams with their eye on the ball and their management is in vision lockstep with them on the main design principals. defense (vs civilian firms) usually has an issue with this since most civilian products are internally developed from needs to market whereas you often have multiple different bodies that have design input on military hardware (design firm, pentagon, politicians, at a minimum).

I don't know about that. Is a lancet or any other conventional loitering munition (which is to say, not using an exotic mode of attack) substantially different than, say, an atgm with a top-attack profile? At least from the perspective of the designer, who isn't necessarily having to account for the secondary factors of drone delivered weapons (such as the moral impact of pervasive, airborne individually directed explosive devices). It seems they have much the same requirements as they had before - how to keep the explosions going out of the tank rather than into it. If anything, they could improve in Ukraine by doubling down - being more armoured/protected and having more powerful guns/munitions, since they have proved most viable at stand-off ranges acting like massive sniper rifles. Now if you were talking about strategists and planners, or even designers working on other categories of systems, your point stands more confidently.

[@p_serdiuk]

To get the optimal amount of operational reliance AND maintainability for any military combat platform requires that the platform places a significant amount of emphasis on maintenance access to components. That is one reason the M1A2 power packs, for instance, are modular, to enable rapid changeout of the engine pack with a reconditioned spare and then send the old one to depot for overhaul and upgrade. This needs to be a uniform design feature throughout the vehicle. Tracks and suspension are one area where developing new designs would be vast improvements over the existing system of road wheels, suspension arms and linked tracks that is essentially 100 years old. It doesn't just apply to tanks. Warships, including nuclear aircraft carriers and submarines are platforms that haven't always been designed with maintenance in mind, and that becomes very important when you are trying to repair battle damage or failed critical components without gutting the entire hull.

My speculations would be: A new armor composite, Cobham was developed in the 1970s. Depleted uranium skins, stand-off spaced-armor, these can be integrated in a new hull and turret. The integration of communication and power lines through this newly-constructed composite, rather than boring holes straight-through, to accommodate cameras and sensor packs and future upgrades for battlefield communications. The Japanese Type 10 claims sufficient protection at a base fourty tons, versus seventy-three tons, along with the integration of cameras, sensors, active protection hard-kill system, and bolt-on advanced reactive armor kit _if desirable._ I expect significant increase in _upper hull_ and _turret_ top-armor, especially! Mobility and repair: I half-way expect adoption of the style of suspension used by Challenger, because [to an extent] it can be built to take a certain maximum weight, be _upgraded _*_to_*_ that weight,_ and accommodate upgrade to a _new_ weight limit. It is vastly easier to repair more completely than torsion-bar suspension, _and_ handles going off-road _much_ better; what it does _not_ do is speeds much over 37 miles per hour. -- BUT -- The U.S. is going to require a hybrid power train that supports all-electric operation, and the weight for batteries has to come from somewhere. Gun: Two guesses: The Rheinmettal 120mm L55, or the Japanese 120mm that is backwards-compatible with the N.A.T.O. ammunition, or can use its own high-pressure load to match performance of the L45 gun _with a shorter barrel._ My money is on a U.S. version of the Japanese gun, probably also using the Japanese robotic autoloader. In many ways, I would expect a new turret to be a mix of developments and capabilities exhibited by the Merkava Mark 4, with the Type 10, and a couple of entirely new communications capability those don't have plus electronic intelligence gathering and electronic countermeasures, and a spectrum of defensive capabilities no one else in the world is fielding yet.
