Abrams Tanks May Have Some Problems in Ukraine - How Serious Are They? - Technology Org

The Armed Forces of Ukraine are using a bunch of different types of Western tanks. Those include German Leopard 1 and 2 tanks, British Challenger 2 and, of course, at least 31 M1A1 Abrams tanks. All of these tanks have certain peculiarities about them and crews have to be prepared for each of these types individually. However, the Abrams main battle tank may pose the most serious problems.

Ukraine absolutely needs main battle tanks. The more the better. And the more advanced the better. However, the West lived in peace for so long that the tank reserves are not that great. NATO countries don’t have that many tanks to spare actually.

On top of that, the choices of which tanks to supply need to be made in a smart way, because Ukraine does not have any experience with the Western-designed tanks, there is no servicing or ammo supply infrastructure there.

And now the Ukrainian Ground Forces have a mish-mash of tanks, which have their own peculiarities:

The Leopard 1A5 is not only the oldest in its architecture, but also has a rifled 105 mm gun. This means that it needs special ammunition, which is not common in NATO anymore.

The Leopard 2s are the most standard, but Ukraine is getting a bunch of different versions of this tank, including 2A4s, 2A5s, 2A5s (Stridsvagn 122) and 2A6s. There are differences between these versions that need to be learned in training.

The Challenger 2 is of the same era as the Leopard 2, but it uses a rifled 120 mm gun, which also required special ammunition.

Finally, the M1A1 Abrams can share ammo with the Leopard 2, but has a multi-fuel turbine engine, instead of a regular reciprocating engine with cylinders and pistons.

Abrams tanks can burn any fuel – diesel, petrol, vodka, doesn’t matter. They are powerful and resilient. However, these gas turbine engines do need a lot of care.

Forbes writes that despite the engines in the Abrams tanks costing an unbelievable amount of money, they can succumb to dust and debris if the crews don’t maintain the filters very well. This is something crews learn during long months of training, but the Ukrainian tankmen had to learn this very quickly.

If the tank filters are not cleaned every 12 hours or so, the damage can be so severe that the engine and possibly the transmission will need to be replaced. Obviously, in a battlefield that could bring the tank to a tragic ending.

How do you clean the filters? Ukrainian Abrams crews will have to rev the tank’s engine to redline twice a day to start the pulse-jet system and blow air through the filters clearing out the dust and debris.

Even with the filters being kept up to, the Arbams will cause some issues to the Ukrainian Ground Forces. These tanks use a lot of fuel and require deep maintenance, which will have to be performed in Poland. Getting them there will not be easy either, because the Abrams is rather heavy at over 62 tonnes.

However, the effectiveness of the main battle tank mostly depends on the tactics. And if the defenders of Ukraine manage to exploit the strong sides of the Abrams well, these tanks will do a lot of damage to the Russian invaders.

Hey question, what was the article/book that this post was on? https://www.tumblr.com/ghirahims-left-shoe/733355856922558464 I am fascinated with 90s/2000s scholarship of the future (at the time) internet and wanted to give it a read, but predictably, dropping the first line into a search engine didn’t do anything.

Thanks!

im so sorry but that screenshot was from an article i was only skim-reading at the tail end of my honours thesis and i didn't find useful for my argument so i never wrote down the citation (and didn't include it in the original post bc it was only ever meant to be a silly thesis-writing anecdote shared with my followers, not like. a broadly shared post for actual discussion. lol). i think someone might have found the source if u look further back in the notes?

EDIT: it's the social implications of the internet by dimaggio et al.! thank u @fredfinch for finding it 💖

#replies.txt #sega-dreamcats #sorry again i rly wish i had noted the citation bc it was a rly good article just. not what i needed at the time lmao #since we're talking abt that post: yes i know the internet has always been tied to capitalist & military ventures so this wasnt new #yes i know this was written after and therefore informed by the dot com bubble burst #yes i know that 1997 citation there is not the citation for the rest of the paragraph #yes i wish i hadnt deleted the post so i could make it non-rebloggable now that we have that feature 🫠

Academia is so left-wing until you actually have to read research papers and then it’s just 20 different papers on why colonization was okay

#I swear to god I read a paper that said the Koreans should’ve thanked the Japanese #and another on why settler colonization was actually beneficial for North Africans #several others I should say #and it’s always like ‘these Africans were so eager to help their new rulers so many of them joined the military and showed theirpatriotism!’#and then you figure out by painfully piecing things together that no. actually. it’s just that the colonizers controlled the economy & jobs.#none of those Africans really had any choice at all— the only way to make money & keep their families alive was through military service #serving for a country you hate to help them suppress other groups just like you. and then the world asks for your *gratefulness*#like no! colonization is fucking bad!!!!#to delete later #was gonna write a fic to vent my emotions but I have neither the time nor the skills required for what I want to do #might try anyways but unlikely #academic discussion: slavery is the last stage and end goal of capitalism and the very principles of American society perpetuate racism #academic research: :( black people have it so easy whites are soooo overhated :( :( :(#also featured here: me vs the character count limit on tags

the skrunklies. Damn the manga version of this story really brings out the fact that dororos entire life and world gets completely uprooted and turned around twice in the span of around a year. he gets taken care of by koyuki and sees earth in a way that’s the complete opposite of what hes been told its like and loves it and decides to abandon his old life to very passionately and singlemindedly become The Most Traditional Ninja Ever. and then the ninja village gets completely disbanded and he has to go to normal people world with koyuki

#itsjust ?????? something #double feature! you’re already a literal space alien #AND you got used to a part of this planet that does not represent everyone’s way of living at all!#Oh you thought the fireflies were beautiful?#Oh you wanted to stay in the village forever?#Fuck you. Take your daughter and buy her a cell phone #i just think its A Lot to expect things to go a certain way and then that gets abruptly uprooted and turned around #and seems even more fucked up to have that happen multiple times super rapid fire #‘ill be part of the invasion force for my home planet’ no you wont.#‘ok then ill be a ninja in this village with the new friends ive made’ no. not that either.#go climb through a minifridge.#basilposting #frog renaissance #i think it can joining the military for trauma

Army recruiters: free Travis Kelce haircut with each enlistment

KANSAS CITY, Mo. – Local Army recruiters are capitalizing on the Travis Kelce-Taylor Swift romance whirlwind by offering FREE haircuts similar to the football star’s signature fade when they enlist. Local barbers have been bombarded by new and returning clients looking for the “Kelce Fade” ever since the tight end and pop singer made their relationship public last summer. “My wife loves Taylor…

This year’s Super Bowl was a weapon of mass distraction. If there’s any justice, future generations will remember the game not for Patrick Mahomes, Travis Kelce, or Taylor Swift but for the US-funded attacks on Palestinian civilians that occurred while so many Americans were glued to their TVs. During the game, watched by well over 100 million people in the United States, Israel launched a bombing raid of Rafah in the Gaza Strip, the most densely populated area on earth. More than 1 million people had fled now-leveled Gaza City to the refugee camps in Rafah and surrounding areas. Palestinians who have survived previous Israeli strikes are now staving off disease, destitution, and fear.

Meanwhile, CBS granted the Israeli government space for an ad about the 130 hostages left in Gaza. This ad, meant to build public support and justify the slaughter of nearly 30,000 civilians in Gaza, spurred 10,000 people to register complaints with the FCC, because the commercial did not disclose that a foreign government had paid for it. Coupled with the Rafah raid, this looks more like military synergy than happenstance.

New England Patriots owner Robert Kraft also spent $7 million on an ad from his organization Foundation to Combat Anti-Semitism. It features Clarence Jones, a 93-year-old former speech writer for Dr. Martin Luther King Jr. Kraft and other pro-war billionaires use the memory of King so much, they should be paying his family indulgences for slandering his name. The ad failed to mention that Kraft has given $1 million to pro-war AIPAC and donated $1 million in 2016 to Donald Trump’s inauguration. Given that Kraft says that the Nazi march in Charlottesville was his motivation to start his foundation (Charlottesville was the one with “good people on both sides,” according to Trump), his hypocrisy is insidious.

Kraft and Israel want the same thing: a blank check to uproot Palestinians from Gaza and build settlements. One can also only imagine if a peace organization tried to buy an ad asking Israel and the United States the question: “How many dead children will be enough?” I suspect it would be denied faster than a public-service announcement about concussions.

The pentagon doesn't understand. They think they can fight fire with fire. They think they can counter a numerical superiority with drones. But the drones can't see past the veils of reality. They can't feel the tension in the air, and in madman's mind. Machines never understand the way politics and number games blend together. It's a complex existential battle of ideology and power - one that drones can never understand.

Huh. Good to know my dad is more outspoken on liberals than gay people I guess???

#we were watching the news on the newest trump drama #and he was talking about how the Biden administration uses more outrageous news on their opposition (trump) to cover up their own stuff #and then a little later something about how 35000 or so people got discharged from the military for being gay comes on #and the featured person had been 'discharged for reasons other than honorable' or somethin #and had been in service for 10 months #and the most my dad had to say about that was that the discharge statement was wrong and would say something like 'admin' instead #bc apparently they don't need a reason for discharge if it's under a year of service #but nothing about the gays so that's a win I guess #he just hates Biden lol

US Developing New Version of Scary Abrams Main Battle Tank - Technology Org

New Post has been published on https://thedigitalinsider.com/us-developing-new-version-of-scary-abrams-main-battle-tank-technology-org/

US Developing New Version of Scary Abrams Main Battle Tank - Technology Org

The M1 Abrams has been in service since 1980. It is still one of the most capable main battle tanks in the world, but even the most common versions the M1A1 and M1A2 are starting to show signs of their design ageing. So, this tank needs to be upgraded, but how?

While the standard M1 Abrams has been in service since 1980, the most common versions are slightly younger. The M1A1 was produced from 1985 to 1992, and the M1A2 – from 1992. In general, the Abrams platform has proven its advantages in battles and so far surpasses the technology of potential enemies. However, it is clear that the Abrams must be developed further, but there are limitations to this.

It’s hard to believe, but the first Abrams weighed 55.7 tonnes. They were equipped with a 105 mm rifled gun and had slightly weaker armour. The M1A1 initially retained this weight, but the M1A1SA grew to 61.3 tonnes and the M1A2 – to 62 tonnes. And that weight gain continued little by little.

The M1A2 SEPv3 Abrams weighs about 67 tonnes. One can look at the tank’s mobility, maintained maximum speed and other dynamic characteristics, but one cannot ignore the fact that, being so heavy, the Abrams is a huge weight on the specialists of military logistics. The US wants to be able to operate globally, but moving such heavy tanks quickly is very difficult.

What is the path of modernization then? Well, upgraded tanks usually get heavier. Additional armour is attached to them because anti-tank weapons, including drones, are being developed faster than tanks. In the past, kilograms were saved by keeping relatively thinner armour on top, but now you can’t even do that – anti-tank drones are cheap and everywhere.

On 2023 September 6 The US Army announced that it had cancelled the planned M1A2 SEPv4 variant and would instead focus resources on the new M1E3 Abrams. The new model will have a modular architecture and will be lighter but with even better protection.

“The Abrams Tank can no longer grow its capabilities without adding weight, and we need to reduce its logistical footprint,” said Maj. Gen. Glenn Dean, Program Executive Officer for Ground Combat Systems. He said that the war in Ukraine showed that crews need to be protected better, but not with added armour.

The M1E3 Abrams is likely to rely heavily on active protection, which is lighter than conventional armour. The US Army promises that the Abrams will remain the most capable main battle tank in the world. The M1E3 version is planned to start service around 2030 and it will continue working well into the next decade.

With the sudden collapse of the Soviet Union in the early 1990s, many of the former empire's resources were sold off to the highest bidder, and their $14 billion space shuttle program was no exception.

Seeking to recoup some of that eyewatering spend, in 1998, the "Buran" (Russia's answer to the American Space Shuttle) was offered up for sale on eBay for $10 million.

No serious offers were received - with most people assuming the listing to be a joke, until the New York Post confirmed the sale, with Russian authorities stating they "actually have two" if anyone is interested.

(Pictured: A later auction of a smaller scale Buran in 2005)

Sensing an opportunity, a group of Aussie entrepreneurs including Australia's first astronaut and the lawyer for Prime Minister Paul Keating offer to lease the shuttle from Russia, to put it on display in Australia during the Sydney Olympics.

After gaining permission from the Kremlin for the lease, in 1999 the Russian military briefly stops bombing Chechnya in order to dismantle the Buran, and it is placed on a barge to be shipped to Sydney on the (soon to be infamous for other reasons) Tampa shipping vessel at a cost of $5 million.

Once in Sydney, after a disastrous few months on display where crowds failed to flock to the shuttle exhibition featuring such compelling educational offerings as "activities is to assist in the development of issues of nutrition and hygiene at home" (an actual quote from their website) - the leasing company declared bankruptcy and washed their hands of the space shuttle completely.

The Buran Gift shop where you could buy soviet space ship themed football jerseys, in case you needed one of those

One of four people listed on the lease, described as a business partner of the Prime Minister, also claims he never knew he was a director of the company, which went on to cause a lot more problems.

This whole debacle presented a slight issue for the cash strapped Russian authorities, who had now only been paid $100,000 for the 9 year lease of the shuttle instead of the $600,000 they were owed. Eventually the decision was made to abandon the once $1 billion Soviet pride and joy in a Sydney carpark, where it resided for a year under a small tarpaulin.

Failed attempts to be rid of the shuttle included a 12 day auction hosted by an LA radio station, where listeners were offered the chance to buy the shuttle for $6 million, however all bids turned out to be pranks and the shuttle remained.

Multiple attempts were also made to sell the shuttle to Tom Cruise, with the exacerbated movie star's representatives repeatedly telling the insistent traders that he was not interested in owning a Russian spaceship.

Eventually a Singaporean group dismantled the shuttle and shipped it overseas, however Russian authorities soon reported they once again had been failed to be paid for the lease. Singaporean representatives responded that they definitely had paid for the shuttle, and that they simply couldn't remember when or how much was paid.

Representing the Russian government, Lawyer Suhaila Turani told the Wall Street Journal “I feel sorry for the Russians. They’re good in space, but they’re very naive in business.”

For a time the shuttle was abandoned in the storage yard of event company Pico, with the company owner telling the Wall Street Journal "I just want this thing out of my life" after three years of being stuck with it.

A few years later the shuttle was found by German journalists dismantled in a junkyard, and it was then bought and shipped to Germany to be put on display a museum, so all's well that ends well (except they dropped it from a crane while trying to set it up, but it polished up okay).
