The MOST POWERFUL AMERICAN Military Machines Ever Built!

There are moments in history when entire battles seem to pivot on the arrival of a single machine.

Not because it is the largest object on the battlefield or the fastest thing in the sky, but because it appears at exactly the moment when every other option has disappeared.

A radio operator makes one desperate call. A convoy commander peers across a horizon filled with duSt. An infantry squad hears the distant rhythm of rotor blades or the unmistakable growl of an approaching engine.

In those moments, steel becomes more than machinery. It becomes confidence, survival, and sometimes the difference between a mission remembered as a victory or one remembered for entirely different reasons.

Military history is often told through the decisions of generals or the courage of soldiers, yet another force quietly shapes every conflict.

Engineers working years before the first shot is fired make choices that ripple across decades.

A stronger transmission, a more reliable weapon, thicker armor, a redundant hydraulic system—details that seem ordinary on a blueprint can decide the outcome of events thousands of miles away.

Some designs fade almost as quickly as they appear, replaced by newer technology before proving themselves.

Others refuse to disappear. They survive changing governments, evolving battlefields, and generations of technological revolutions because they continue solving problems no replacement has managed to solve better.

The United States has built countless military vehicles, aircraft, and weapons throughout its history. Most served their purpose and quietly retired.

A select few reshaped military doctrine itself. Enemy planners studied them obsessively. Allies built strategies around them.

Soldiers trusted them under circumstances where trust could not be earned by advertising or reputation alone.

These machines accumulated something far more valuable than impressive specifications. They built records in real operations, where every success and every failure carried consequences impossible to simulate.

One of the clearest examples emerged during the closing years of the Cold War, when American planners confronted a difficult reality.

Soviet armored forces possessed enormous numerical strength across Europe. If conflict erupted, American crews would likely face hundreds of enemy tanks advancing simultaneously across open terrain.

The United States needed more than another armored vehicle. It needed one capable of surviving against advanced anti-tank weapons while striking accurately before an opponent could react.

That requirement eventually produced the M1 Abrams. Officially entering service in 1980, the tank represented years of experimentation, changing priorities, and difficult engineering compromises.

Earlier American tanks had demonstrated strengths, but military planners wanted something dramatically more capable. Protection had to increase without sacrificing mobility.

Firepower needed to remain effective against future threats rather than simply matching existing ones. Electronics would have to improve target acquisition under conditions where visibility might be measured in seconds.

The result looked imposing even before its combat record began. Weighing roughly 68 tons in many later configurations, the Abrams appeared almost too massive to move with agility.

Yet beneath its armor sat one of the most unusual powerplants ever installed in a frontline tank.

Instead of a conventional diesel engine, engineers selected the Honeywell AGT1500 gas turbine. The decision immediately divided opinions.

Gas turbines were famous in aviation, not armored warfare. They delivered remarkable power while producing comparatively smooth operation, but they also demanded enormous amounts of fuel.

Military logisticians quickly realized they faced a new challenge. Every gallon carried to frontline units would disappear faster than with previous tanks.

The turbine generated approximately 1,500 horsepower, allowing the Abrams to accelerate with surprising speed despite its immense weight.

On favorable terrain it could exceed 45 miles per hour, an extraordinary figure for a vehicle carrying such extensive armor.

Even more remarkably, the engine accepted multiple fuel types. Jet fuel remained standard, but diesel, kerosene, and gasoline could also keep the tank moving when circumstances required.

Flexibility came at a price. Fuel consumption became legendary. During extended operations, supply convoys devoted enormous effort simply keeping Abrams formations fueled.

At idle, the turbine continued consuming significant amounts. During sustained movement across combat zones, planners calculated logistics almost as carefully as tactics.

Critics questioned whether such appetite could ever justify itself. History answered during Operation Desert Storm.

In early 1991, coalition forces prepared for one of the largest armored offensives since the Second World War.

Iraqi formations fielded large numbers of Soviet-designed armored vehicles, including T-72 tanks regarded as serious opponents.

Many analysts expected difficult engagements between heavily equipped armies operating across open desert. Instead, events unfolded with astonishing speed.

Among the defining moments stood the Battle of 73 Easting in February 1991. American cavalry units equipped with M1A1 Abrams tanks and M3 Bradley Cavalry Fighting Vehicles advanced through blowing dust and limited visibility while searching for Iraqi Republican Guard positions.

Navigation relied heavily on advanced equipment and disciplined crews maintaining formation under conditions where visibility frequently disappeared altogether.

Rather than stumbling blindly into prepared defenses, American forces located Iraqi units firSt. The Abrams possessed sophisticated thermal imaging systems capable of identifying targets invisible to the naked eye.

Crews detected enemy vehicles through darkness, dust, and smoke before opposing tank commanders even realized they had been found.

Once contact began, events accelerated dramatically. American fire-control computers calculated firing solutions rapidly while stabilized main guns remained accurate during movement.

Iraqi crews often struggled to identify incoming threats before their own vehicles came under fire.

Combined with superior training and coordinated tactics, technological advantages produced overwhelming results. The engagement lasted only minutes.

Nearly two hundred Iraqi armored vehicles were destroyed or abandoned during the battle, while American armored losses remained astonishingly low.

Military historians continue studying the engagement not because technology alone determined the outcome, but because training, leadership, reconnaissance, communications, and engineering combined into a level of battlefield effectiveness rarely witnessed on such a scale.

For the Abrams, the battle permanently transformed its reputation. No longer was it merely an expensive experimental design with an unusually thirsty engine.

It had demonstrated precisely why engineers accepted those logistical burdens. Success did not freeze development.

Military technology evolves continuously, and every deployment revealed opportunities for refinement. Improved armor packages strengthened protection against emerging anti-tank weapons.

Electronics advanced with each generation. Thermal sights became clearer. Digital communication networks allowed tanks to exchange information far more efficiently than crews during the Cold War could have imagined.

Later variants such as the M1A2 incorporated increasingly sophisticated battlefield management systems, allowing commanders to share target information almost instantly across formations.

Subsequent upgrades eventually produced the M1A2 SEPv3 configuration, integrating improved power systems, enhanced sensors, modernized communications, and compatibility with active protection technologies intended to defeat incoming threats before impact.

Remarkably, the essential platform remained recognizable decades after entering service. Many weapons enjoy brief periods of dominance before advancing technology leaves them behind.

The Abrams instead adapted repeatedly, extending its operational relevance into entirely different conflicts than those envisioned by its original designers.

Its story stretched from the deserts of Kuwait and Iraq into urban environments where armored warfare looked nothing like the massive tank battles anticipated during the Cold War.

Crews learned that survivability depended not only upon armor thickness but upon coordination with infantry, reconnaissance assets, aviation, and logistics.

The tank remained extraordinarily capable, yet modern warfare increasingly emphasized combined arms rather than isolated platforms.

Still, there existed one limitation no amount of armor could eliminate. Even the fastest tank could not instantly appear wherever soldiers needed immediate assistance.

Sometimes frontline units became engaged across terrain inaccessible to heavy vehicles. Sometimes enemy positions threatened friendly troops from locations impossible for armored formations to reach quickly enough.

In those moments, commanders looked upward rather than forward. Long before a tank could arrive, another machine often announced itself with an unmistakable sound echoing across the battlefield.

It was not elegant by fighter standards. It was not especially faSt. Many aviation experts once considered it outdated before it had fully proven itself.

Yet whenever soldiers found themselves pinned under hostile fire, few aircraft inspired greater confidence than the one designed around a weapon so enormous that engineers built almost everything else to fit around it.

The story of the A-10 Thunderbolt II would become one of the most unusual chapters in modern military aviation.

The A-10 Thunderbolt II was born from a question that seemed almost old-fashioned during the early 1970s.

Military aviation was moving toward aircraft that flew faster, climbed higher, and carried increasingly sophisticated electronics.

Yet combat experience suggested that speed alone could not solve every problem. Soldiers on the ground often needed something very different.

They needed an aircraft willing to descend into dangerous airspace, identify friendly forces with precision, and remain overhead long enough to influence a battle unfolding minute by minute.

Designers approached the project from the battlefield upward rather than from the sky downward. Instead of beginning with aerodynamic elegance, they began by asking what an infantry platoon or armored column would expect from an aircraft arriving in the middle of a desperate engagement.

Endurance mattered. Survivability mattered. Accuracy mattered. Everything else became secondary. At the heart of that philosophy sat the GAU-8/A Avenger cannon.

The weapon was unlike anything previously mounted on an operational American aircraft. Its seven rotating barrels fired 30-millimeter ammunition at an extraordinary rate, reaching roughly 3,900 rounds per minute.

The cannon’s sheer size dictated almost every major design decision surrounding it. Engineers positioned it along the aircraft’s centerline as closely as possible, shifting it slightly to accommodate the nose landing gear.

The ammunition drum occupied much of the forward fuselage, while the aircraft itself effectively became a platform built to carry one enormous gun.

Yet reducing the A-10 to its cannon alone overlooks what truly made it remarkable. Combat aircraft are expected to avoid hostile fire whenever possible.

The A-10 accepted that avoiding every threat would be impossible. Engineers instead assumed the aircraft would occasionally be hit and designed it to keep flying afterward.

Its cockpit rested inside a titanium protective enclosure commonly described as a “bathtub,” shielding the pilot from significant ground fire.

Redundant hydraulic systems controlled the flight surfaces, while a manual backup system allowed pilots to retain control even if both hydraulic circuits failed entirely.

Fuel tanks sealed themselves after sustaining damage, reducing the likelihood of catastrophic fuel loss. The two engines sat high on the rear fuselage, separated by enough distance that damage to one would be less likely to disable the other.

The result resembled an aircraft built with stubborn determination rather than graceful lines. Pilots soon demonstrated exactly why those engineering decisions mattered.

Operational reports from conflicts in Iraq and Afghanistan documented aircraft returning safely despite sustaining damage that would likely have ended the mission of many other designs.

Missing sections of control surfaces, heavily damaged wings, disabled hydraulic systems, and engine failures appeared in maintenance photographs that later circulated throughout military aviation communities as examples of extraordinary survivability.

Those stories reinforced a reputation already growing among the troops below. Ground forces valued more than firepower.

They valued communication. Unlike aircraft racing through an engagement at extremely high speed, the A-10 could remain in the area, orbiting while pilots maintained direct communication with forward air controllers.

Soldiers describing enemy positions often spoke directly with the pilot supporting them. That dialogue allowed attacks to be adjusted almost immediately as battlefield conditions evolved.

The psychological effect proved nearly as important as the weapons themselves. When troops heard the distinctive sound associated with an A-10 arriving overhead, they knew assistance had reached them.

That confidence cannot easily be measured on engineering diagrams, yet countless veterans have described it as one of the aircraft’s greatest strengths.

Ironically, the airplane spent much of its career defending its own existence. As technology advanced, proposals repeatedly emerged suggesting that faster multirole fighters could assume close air support responsibilities while performing many additional missions.

On paper, replacing a highly specialized aircraft with a more versatile platform appeared logical. Operational experience repeatedly complicated that argument.

Supporters of the A-10 acknowledged that modern fighters excelled in numerous roles, but they emphasized that close air support demanded unique qualities not easily duplicated.

Flying low enough to identify friendly troops, remaining over the battlefield for extended periods, absorbing occasional damage, and delivering highly accurate fire under difficult conditions required an unusual combination of endurance, visibility, and resilience.

Each attempt to retire the aircraft encountered resistance from soldiers and Marines who had depended upon it during combat operations.

Even decades after entering service in 1977, discussions regarding its future continued. Combat observations from more recent conflicts reminded military planners that certain battlefield requirements had not disappeared simply because technology evolved elsewhere.

The A-10 became a lesson in specialization. Sometimes excellence in one mission outweighs competence across many.

The same principle influenced another vehicle whose early history proved far more controversial. When the Bradley Fighting Vehicle entered service in 1981, it immediately found itself caught between competing expectations.

Some observers viewed it as insufficiently protected to accompany tanks into major engagements. Others believed it had grown too large and expensive for the simple role of transporting infantry.

It seemed to occupy an uncomfortable middle ground that satisfied neither traditional definition. Criticism arrived quickly.

Defense analysts questioned whether combining troop transport with significant firepower represented practical military planning or unnecessary compromise.

Congressional discussions reflected those concerns, while public debates occasionally portrayed the Bradley as an example of excessive complexity within defense procurement.

Reality would eventually test those assumptions. Unlike the Abrams, whose purpose centered primarily upon armored combat, the Bradley carried infantry while simultaneously providing supporting fire through its 25-millimeter M242 Bushmaster chain gun and TOW anti-tank missile system.

This combination fundamentally changed how mechanized infantry operated. Rather than simply delivering soldiers before withdrawing, the Bradley remained integrated into the fight.

Infantry units could dismount under armored protection while the vehicle continued providing suppressive fire against enemy positions.

Commanders gained flexibility impossible with simpler armored personnel carriers. Operation Desert Storm again supplied the decisive examination.

During coalition advances across Kuwait and Iraq, Bradley crews repeatedly encountered enemy armored vehicles. Equipped with anti-tank missiles and supported by highly trained crews, they proved unexpectedly effective against Iraqi armor.

By the campaign’s conclusion, Bradley Fighting Vehicles had destroyed more Iraqi armored vehicles than the Abrams itself.

That statistic often surprises people unfamiliar with the campaign. It does not imply that the Bradley surpassed the Abrams as a tank.

Rather, the vehicle’s numbers, mobility, and frequent contact with advancing formations created numerous opportunities where Bradley crews engaged hostile armor before tanks reached the same positions.

Its reputation continued evolving during later operations in Iraq. Urban combat demanded equipment capable of moving infantry safely through streets where threats could emerge from multiple directions.

The Bradley’s ability to transport soldiers directly into contested neighborhoods while providing immediate supporting fire became invaluable.

Infantry could rapidly dismount, secure buildings, conduct searches, and return to protected transport without losing armored support.

Successive upgrades improved survivability, electronics, and mobility while preserving the original concept. Later configurations incorporated stronger armor, enhanced situational awareness systems, and improved communications suited for increasingly networked battlefields.

Even its eventual replacement, the XM30 program, retained the underlying philosophy that had once attracted so much criticism.

Sometimes history vindicates ideas that initially appear uncertain. Yet neither tanks nor infantry fighting vehicles can cross mountain ranges, rivers, or vast distances with the speed demanded by rapidly changing operations.

For that, military planners have long relied upon helicopters. By the late 1970s, one aircraft had become almost inseparable from American military operations.

The UH-1 Huey had defined an entire era during the Vietnam War, transporting troops, evacuating casualties, delivering supplies, and supporting countless missions under extraordinary conditions.

Replacing such an aircraft represented an enormous challenge. The successor needed greater lifting capability, improved reliability, increased survivability, and the flexibility to operate across climates ranging from frozen mountains to scorching deserts.

That successor arrived in 1979. The UH-60 Black Hawk immediately demonstrated that it represented more than a simple replacement.

Its twin-engine configuration increased reliability, while more powerful systems allowed it to transport approximately eleven fully equipped soldiers or heavy external cargo loads approaching 2,600 pounds.

Cruising speeds around 183 miles per hour expanded operational reach, enabling commanders to reposition forces more rapidly than before.

Over time, the Black Hawk became one of the most recognizable helicopters in modern military history.

Its missions extended far beyond troop transport. Medical evacuation crews relied upon specially equipped variants to retrieve wounded personnel from isolated locations where roads either did not exist or remained too dangerous for ground vehicles.

Search and rescue operations depended upon the helicopter’s range and lifting capability. Special operations units incorporated modified versions into missions requiring precision flying under extremely demanding conditions.

From Grenada to Panama, from the deserts of Kuwait and Iraq to the rugged terrain of Afghanistan, the Black Hawk established a reputation built upon consistency.

Soldiers often described it with remarkable simplicity. It was the helicopter that arrived when called.

That reputation faced one of its greatest tests during the Battle of Mogadishu on October 3 and 4, 1993.

The events unfolding above the Somali capital became known worldwide after two UH-60 Black Hawks were struck by rocket-propelled grenades during an operation targeting senior militia leaders.

The downed helicopters transformed the mission immediately, shifting priorities toward protecting surviving crew members and conducting rescue operations under exceptionally difficult circumstances.

The battle demonstrated not only the risks associated with helicopter operations in dense urban environments but also the extraordinary commitment required to recover crews once aircraft went down.

The Black Hawk itself remained central to military operations long afterward. Improved variants, including the UH-60M, introduced stronger engines, advanced rotor systems, digital cockpits, and enhanced avionics, ensuring that an aircraft first fielded during the late 1970s continued meeting twenty-first century operational requirements.

Its story, however, also illustrated a broader truth. Some machines become famous because of spectacular victories.

Others earn lasting respect because generation after generation simply refuses to imagine military operations without them.

Long before satellites linked commanders across continents and before digital battle maps appeared inside armored vehicles or helicopter cockpits, American military engineers learned a lesson that has never gone out of date.

Sophisticated technology can transform warfare, but only if it continues working after the dust settles, after the weather turns hostile, and after countless hours of relentless use.

Reliability is rarely the most exciting quality in a weapon, yet history repeatedly shows that dependable equipment often shapes campaigns more profoundly than revolutionary ideas that never mature beyond prototypes.

That lesson is embodied by one of the oldest weapons still serving on modern battlefields.

The M2 Browning heavy machine gun entered American service in 1933, but its origins reach back even further.

During the closing stages of the First World War, legendary firearms designer John Browning responded to military requests for a weapon capable of engaging tougher targets than earlier machine guns could reliably defeat.

The result evolved into a design chambered for the powerful .50 BMG cartridge, combining long-range accuracy, remarkable durability, and tremendous versatility.

Few military engineers could have imagined how long that design would remain relevant. Entire generations of combat aircraft have appeared and disappeared while the M2 continued serving.

Armored vehicles carrying it have retired to museums. Naval vessels mounting it have been decommissioned.

Yet the weapon itself remains firmly in frontline service, accompanying soldiers into environments completely unimaginable when its blueprints first took shape.

Its specifications explain only part of that extraordinary longevity. Depending on configuration, the M2 maintains a sustained rate of fire generally between 450 and 600 rounds per minute.

Its effective range against aerial targets extends well beyond 1,800 meters, while its powerful ammunition allows it to penetrate light armor, disable vehicles, engage fortified positions, and provide suppressive fire across enormous distances.

More important than any individual statistic is the weapon’s remarkable simplicity. Armorers can repair and maintain it under field conditions using comparatively basic tools.

Its operating system has been refined over decades rather than fundamentally reinvented. Soldiers assigned to vehicles, defensive positions, helicopters, patrol boats, and countless other platforms have learned to trust that if the trigger is pressed under proper conditions, the weapon will almost certainly perform exactly as expected.

That trust has been earned across nearly a century. The M2 has served during the Second World War, the Korean War, the Vietnam War, Operation Desert Storm, Iraq, Afghanistan, and numerous smaller operations spanning almost every climate on Earth.

It has functioned in desert heat exceeding 130 degrees Fahrenheit, endured freezing temperatures below minus 40 degrees, resisted blowing sand, tropical humidity, torrential rain, and saltwater environments that challenge even modern equipment.

Engineers often speak about lifecycle planning measured in decades. The Browning exceeded nearly every prediction.

Its endurance reflects a philosophy sometimes overlooked during discussions about advanced military technology. Innovation does not always require replacing successful designs.

Sometimes genuine innovation involves recognizing when a proven solution continues outperforming newer alternatives. By the early twenty-first century, American military forces possessed an extraordinary collection of machines representing different generations of engineering philosophy.

The Abrams demonstrated overwhelming armored strength combined with continuously evolving electronics. The Bradley blended mobility, infantry support, and armored protection into a versatile combat vehicle.

The A-10 embodied uncompromising specialization, sacrificing elegance for effectiveness in close air support. The Black Hawk became the dependable bridge connecting soldiers across impossible distances.

The M2 Browning represented timeless mechanical reliability refined through decades rather than reinvented overnight. Individually, each machine solved a specific military problem.

Together, they revealed something larger about American defense planning. Despite dramatic advances in electronics, precision weapons, and digital communications, the military repeatedly invested in equipment designed around survivability.

Engineers assumed machines would encounter damage rather than avoid it entirely. They expected crews to operate under harsh conditions where maintenance opportunities remained limited.

They recognized that battlefields rarely unfold according to ideal circumstances. This philosophy became especially visible during operations conducted after the Cold War.

Urban combat across Iraq demanded vehicles capable of protecting troops while navigating confined streets filled with constantly changing threats.

Mountain operations in Afghanistan required helicopters capable of reaching isolated outposts where conventional transport proved impossible.

Air support often depended less upon maximum speed than upon pilots willing to remain overhead, carefully coordinating with soldiers below.

Heavy machine guns protected convoys, observation posts, and patrol bases using technology whose basic operating principles dated back generations.

Modern conflicts continually challenged assumptions about future warfare. Military planners had once expected enormous armored battles across Central Europe.

Instead, they confronted insurgencies, counterterrorism operations, urban fighting, and complex multinational campaigns stretching across diverse environments.

Remarkably, machines originally developed for entirely different strategic scenarios adapted successfully because their core engineering remained fundamentally sound.

Even discussions regarding replacements often reinforced that reality. Programs intended to succeed existing platforms faced enormous expectations.

Any replacement for the Abrams would need to match decades of proven combat performance while introducing meaningful improvements.

Future aircraft competing with the A-10 confronted not only technical comparisons but also the confidence ground forces had developed through years of operational experience.

New infantry fighting vehicles inherited lessons learned from the Bradley rather than abandoning them. Helicopter development programs acknowledged the Black Hawk’s enduring strengths even while pursuing greater speed and range.

Replacing successful equipment proved far more complicated than introducing new technology. Experience accumulated value impossible to manufacture quickly.

Battlefield reputation develops slowly through countless individual moments rarely appearing in official histories. A tank crew survives an ambush because armor performs exactly as intended.

A wounded service member reaches advanced medical care because a helicopter lands despite challenging weather.

Infantry pinned behind cover hears an approaching aircraft and knows relief has arrived. A convoy continues moving because a heavy machine gun remains operational after hours of sustained firing.

Those moments become institutional memory. They influence procurement decisions, tactical doctrine, and military culture far beyond technical evaluations or laboratory testing.

Historians often describe wars through decisive campaigns or famous commanders, yet equipment quietly shapes possibilities available to those commanders from the very beginning.

Strategies emerge around capabilities already present. Operational plans assume certain machines can accomplish specific tasks because decades of evidence demonstrate they usually do.

The machines themselves never determine victory alone. Training, leadership, logistics, intelligence, discipline, and countless human decisions remain decisive.

The Battle of 73 Easting highlighted superior preparation alongside technological advantages. The A-10 succeeded because highly trained pilots coordinated precisely with ground controllers.

Bradley crews maximized their vehicles through disciplined tactics rather than relying upon firepower alone. Black Hawk pilots operated under extraordinary pressure because skilled crews continually refined demanding procedures.

The M2 Browning proved effective because generations of soldiers mastered its operation and maintenance. Technology amplified human ability.

It never replaced it. That distinction explains why many of these machines remain relevant decades after their introduction.

The Abrams continues receiving upgrades because its underlying design possesses exceptional growth potential. Modern thermal imaging, networking capabilities, and improved protection systems allow it to confront threats unimaginable during its original development.

The Black Hawk has evolved through progressively more capable variants incorporating digital cockpits, improved engines, and advanced navigation systems while preserving the rugged airframe trusted across multiple generations.

The Bradley likewise absorbed new armor packages, improved optics, enhanced electronics, and greater survivability without abandoning the combined-arms concept that originally defined it.

Even the A-10, despite repeated retirement discussions, demonstrated qualities difficult to replicate completely within broader multirole aircraft designs.

The Browning required perhaps the fewest fundamental changes of all. Sometimes the most enduring engineering achievement lies in creating something that requires surprisingly little correction.

Looking across more than half a century of American military operations reveals an unexpected pattern.

These machines appeared in dramatically different conflicts fought against very different opponents under changing political circumstances.

Yet commanders repeatedly turned toward the same trusted equipment because reliability transcended strategic fashion. The geography changed.

The climate changed. The mission changed. The machines adapted. Perhaps that is the true measure of consequential military engineering.

Not whether a design introduces revolutionary technology for a brief moment, but whether it continues solving critical problems long after the circumstances of its creation have disappeared.

The M1 Abrams emerged from Cold War fears yet proved itself in Middle Eastern deserts.

The A-10 survived arguments about obsolescence because soldiers repeatedly demonstrated its continuing value. The Bradley transformed skepticism into confidence through operational performance.

The UH-60 Black Hawk became synonymous with mobility across continents and generations. The M2 Browning quietly approached a century of service while remaining one of the most trusted weapons ever fielded by the United States military.

Each machine tells a different story. Together, they reveal a single principle that has guided some of America’s most enduring military engineering successes.

When the pressure becomes overwhelming, when conditions are at their worst, and when lives depend upon equipment functioning exactly as intended, history rarely remembers the newest machine.

It remembers the one that worked.
