The struggle over Avdiivka is one of the best illustrations of the change in the conflict to a war of attrition, logistics, and determination, as well as tanks and guns. After several months of holding the positions, the Russian leaders decided to launch a big assault on the city, wrapping it up and changing the situation in the eastern part of Ukraine. Their concept was heavily reliant on numbers – they went several times beyond the quantity of minimally trained and equipped troops, and that which most of the witnesses termed “human wave” attacks. As U.S. officials at the time were saying, Russia was prepared to keep pushing large numbers of poorly trained troops into the frontline without giving a damn about the losses.

Those casualties were overwhelming. Ukrainian commanders put the number of Russian soldiers killed or wounded at almost 47,000, with up to 17,000 dead. Nevertheless, the city was eventually captured by Russia. The win came at such a price that a lot of people have doubted its worth. Britain’s defense ministry estimated Russian tank losses at over 400 in the fighting, well above the population of Avdiivka before the war. The analysts said that Moscow had to take units from other fronts just to keep the offensive going, an indicator of the Kremlin’s determination to hold ground no matter what the cost.

Ukraine’s version of events was no less complex. Avdiivka’s defense was impeded by ammunition shortages, diminishing Western aid, and—most unexpectedly—poor fortifications. Satellite imagery indicated that the trench lines to the west of the city were shallow and rudimentary, nothing at all like the multiple-layered defenses Russia had established in the south, complete with tank traps, dragon’s teeth, and interlocking trench systems. American officials in private admitted concern that Ukraine had not spent enough on defensive positions in the early going, a shortage painfully clear after the Russian attack broke through.

The difference with Russian engineering was stark. Close to villages such as Verbove, Russia’s defenses were virtually impregnable in Ukraine’s counteroffensive. Along Avdiivka, Ukrainian lines were exposed and underprepared by comparison. Kyiv officials acknowledged resources were thin and much of the attention had been given to offensive action and not digging in. Establishing solid defenses was regarded as costly and less immediate—until it came too late.

The equipment losses highlighted the war’s ugly math. The Ukrainian intelligence stated that Russia has lost more than 7,200 tanks and nearly 14,000 armored personnel carriers since the invasion began. In Avdiivka alone, Ukraine lost some 50 combat vehicles, but Russia lost nearly 700. That kind of ratio cannot be maintained indefinitely. Moscow turned to deploying lightly armored vehicles to transport troops, a last-ditch improvisation that says much about the strain on its inventory.

Western aid has been the key to Ukraine’s capacity to continue the combat. American and European deliveries of ammunition and air defenses have maintained their front lines, but setbacks in new appropriations took a heavy toll during fighting. Shells and interceptors dwindled, and American officials openly threatened that not keeping the support could have implications far outside of Ukraine. Most in Kyiv felt that the loss of Avdiivka was not because of low fighting spirit, but because important supplies were trapped in a political deadlock.

Manpower is also an issue. Russia has relied on minorities, convicts, and conscripts from poorer areas to make up its numbers. Ukraine’s troops, on the other hand, tend to be older, better educated, and more motivated, but the average age on the front lines has now risen over 40. Hundreds of days have passed since many of them have had a break from combat, and the toll is obvious.

There is discontent among Russian troops as well. Footage has been leaked of troops griping about suicidal missions, inadequate leadership, and substandard equipment. The Kremlin’s ability and willingness to accept enormous casualties in pursuit of incremental advances further undermined morale, even if threats of punishment keep most compliant.

Tactically, Avdiivka’s capture does create new avenues for Russian advances, but no one imagines that Moscow can drive much further. Its soldiers are weary, and reserves are thin. Ukraine, meanwhile, is digging fresh defensive lines outside the city, but short of a surge in Western aid, additional city strongholds might be in jeopardy. European factories are ramping up production of ammunition, but the pace of acceleration has been glacial. The U.S. has already prepared weapons to be shipped, but politics have held them back from reaching the front lines.

Fundamentally, the war has become less a matter of maneuver and more one of endurance. Russia has taken awful losses in men and equipment, yet it retains reserves and the ability to continue at this rate for years. Ukraine, by contrast, must depend on the stream of Western supplies and the will of its soldiers to remain in the contest.

The Battle of Avdiivka encapsulates the spirit of this war: high cost, modest returns, and results determined as much by political choice as by fighting. It was a Russian victory in name only—a battle which can be expected to end up costing more than the territory it gained.

The F-15EX Eagle II is not just a souped-up variant of an old fighter jet; it is actually a strategic move by the U.S. Air Force to sustain its flexibility and lethality in the face of evolving dangers and reduced funding. The Eagle II, through blending the classic DNA of the first F-15 with cutting-edge technology, offers a clean, revamped but not a brand-new one.

From Cold War Warrior to 21st-Century Workhorse

The F-15 Eagle, which was first designed during the Cold War era, was a revolutionary aircraft, designed for air superiority with unprecedented speed, agility, and power. Gradually, it evolved into a multi-role aircraft, and the F-15E Strike Eagle variant added precision strike capability to the picture. Its adaptability aided in making it one of the most sought-after aircraft, not only with the U.S. but also with allied air forces worldwide.

The F-15EX Eagle II harnesses that tried-and-tested airframe and reimagines it for today’s combat environments. It may look familiar on the outside, but with the upgrades behind the facade, it’s an entirely new creature.

Next-Gen Tech Under the Hood

What distinguishes the F-15EX as properly modern is its onboard technology. It features cutting-edge avionics, improved radar, and BAE’s EPAWSS (Eagle Passive/Active Warning and Survivability System)—a next-generation electronic warfare suite that provides the aircraft with real-time threat detection, jamming, and self-defense capabilities.

EPAWSS is not only a defense system; it’s based on a digital foundation that facilitates constant software updates and modular upgrades. That allows the F-15EX to adapt rapidly to future threats without an extensive overhaul.

Firepower and Range: The Ultimate Missile Truck

Where the F-15EX truly excels is in its ordnance capacity. It can handle as much as 30,000 pounds of ordnance, consisting of 16 air-to-air missiles-more than any other fighter in service today. It’s the ultimate “missile truck,” capable of remaining at a standoff distance while raining down a deluge of long-range missiles.

Its payload range is already massive, but can be stretched with conformal and external tanks. And while stealth jets count on hidden weapon bays to remain radar-invisible, the F-15EX doesn’t hide its weapons, embracing them. From the AIM-120D through the forthcoming AIM-260 to standoff strike weapons such as JASSM-ER, the aircraft can carry almost any U.S. munition.

Team Player: Teaming with Stealth Jets

The Eagle II wasn’t designed to fly solo—it’s supposed to fly in support of fifth-gen fighters like the F-22 and F-35. Here, the F-15EX stays in the rear while stealthier aircraft penetrate hostile airspace, collect targeting information, and feed it back. And then the F-15EX brings the hammer down, firing massive missile barrages without exposing itself.

This makes the jet particularly worthwhile in large theaters such as the Indo-Pacific, with its long distances and logistics involved. Its recent deployment to Kadena Air Base in Japan suggests the Air Force’s intentions to make use of the F-15EX’s range and payload in that area.

Closer to home, the F-15EX is also replacing older F-15C models in Air National Guard squadrons, where its reliability, ease of maintenance, and infrastructure compatibility make it a smooth transition.

Price Tag and Production Perspective

The F-15EX is not inexpensive. Its unit price has gone up from $80.5 million to as much as $97 million in later lots, barely higher than the F-35A’s $82.5 million flyaway cost. Raw cost comparisons can be deceptive, though. The Eagle II gains from being compatible with current infrastructure and parts it carries over from earlier F-15s, which reduces the cost of entry and upkeep in the long term.

It’s also a strategic commodity for the defense industrial base. Maintaining the F-15 line open prevents the U.S. from having to depend solely on a single fighter platform and provides procurement flexibility—a welcome commodity in an uncertain or production-delays environment.

Built to Last—and Adapt

Looking down the road, the F-15EX will have service into the 2050s. It’s not attempting to be a stealth plane, nor is it attempting to replace one. Rather, it closes a gap, providing unmatched firepower, range, and upgrade capacity that fifth-gen fighters simply cannot at scale.

Whether on homeland defense missions, patrolling disputed areas with allies, or augmenting strike packages in support of stealth fighters, the F-15EX demonstrates there’s still space in the air for intelligent, effective upgrades of tried platforms.

The F-15EX is a modern answer to a complex problem—how to stay ready for high-end warfare without betting everything on one expensive, stealthy solution. It’s fast, it’s flexible, and it’s here to bridge the gap between legacy systems and the future of air combat.

The rollout of the B-21 Raider was not just a symbolic unveiling—it marked a new chapter in American airpower. As the first new U.S. bomber in three decades, its formal unveiling at Northrop Grumman’s Palmdale plant was an unambiguous message from the Pentagon: modernize the nuclear triad and enhance conventional strike capacity to remain ahead of fast-changing global threats, notably from Russia and other advanced competitors.

From its initial design phase, the B-21 was constructed on three fundamental principles: survivability, adaptability, and technological flexibility. In contrast to the B-2 Spirit that preceded it, the Raider was designed from scratch to excel in heavily defended airspace.

Its flying-wing shape might appear familiar, yet the advances are considerable: high-aspect-ratio outer wings to provide improved high-altitude lift, a streamlined W-shaped trailing edge, and engine inlets blended far back into the airframe to reduce its radar and heat signature. Even the windscreen is optimized, providing pilots with enhanced vision during aerial refueling and streamlining maintenance for ground crews.

Internally, the B-21 mission systems reflect a bias toward mature but advanced technology. Designed alongside major industry partners such as Pratt & Whitney, BAE Systems, and Collins Aerospace, the bomber combines mature radar and electronic warfare suites to minimize risk and stay on course with development.

It can deliver nuclear weapons and conventional munitions and will be the backbone of the Air Force bomber fleet, complemented by modernized B-52s. An open-systems design provides the ability to quickly modify it with new functionality to address emerging threats.

Tactically, the B-21 is built for deep penetration missions, capable of spending time in contested airspace and striking high-priority targets with accuracy. Its longer range allows it to strike directly from U.S. bases, rather than forward-deployed positions that are at risk of being struck by a missile attack.

Still, this operating model places significant stress on the Air Force’s tanker fleet—a challenge that is exacerbated by the aged KC-135 tankers and the ongoing struggles with the KC-46 program. Supporting 100 B-21s will demand additional tankers and higher-speed refueling capabilities, especially for the long-range Pacific missions, as Gen. Randall Reed of U.S. Transportation Command pointed out.

Astoundingly, the program has progressed with a discipline rarely observed in major defense programs. At least six bombers are on the assembly line, and flight testing is already underway at Edwards Air Force Base.

Through performing thorough ground testing and using an experimental aircraft to resolve software and integration issues at an early stage, which are both part of Northrop Grumman’s strategy, the number of changes made to the flight test has been kept very low. In the first year of flight testing, as stated by Northrop Grumman Aeronautics Systems President Tom Jones, Raider has only needed one software update, a deviation from the norm in the development of new weapons.

Keeping the fleet serviceable over decades of flight has also been a matter of priority since day one. The Air Force is testing Environmental Protection Shelters at Ellsworth Air Force Base to protect bombers against harsh weather, increase their lifespan, and allow flightline maintenance for more rapid turnaround times.

And yet, the B-21 is not completely immune to the familiar pitfalls of U.S. defense procurement. Official cost estimates are kept under wraps, but estimates project the program’s overall price tag at more than $203 billion over three decades.

Unit costs have risen from $550 million in 2010 dollars to almost $700 million in 2022 dollars, and historical precedent indicates that long-term ownership expenses would readily double that amount. Critics, such as the Stimson Center, caution that excessively rosy cost projections, unrealistic promises, and political momentum frequently sustain defective or over-budget projects for far longer than they should exist.

This bomber’s development is also only one aspect of a much larger modernization drive. The Air Force is also developing the Next Generation Air Dominance fighter, Sentinel ICBM, and a stealthy next-generation tanker, while the Navy is working on new frigates and submarines.

A number of these projects are already behind schedule or over budget, contributing to fears that Pentagon spending could be as much as $1.5 trillion per year in the next decade. Unless there is strict fiscal responsibility, the U.S. runs the risk of creating a force that is technologically superior but economically unsustainable.

The B-21 Raider is the epitome of American aerospace engineering—stealthy, flexible, and designed to counter the most daunting strategic challenges of the 21st century. But whether it lives up to its potential will rest not solely on its technology, but on prudent budgeting, intelligent procurement, and an honest vision for the future of U.S. airpower.

Contemporary naval warfare is progressively influenced by the competition to create weapons that improve their effectiveness, adaptability, and cost. One example of such a weapon is the QUICKSINK program U.S. Air Force, which acts exactly in this context by providing a simple but extremely powerful method of sinking enemy ships. The U.S. is currently facing the problem of how to maintain its naval supremacy in the Indo-Pacific region without directly competing with ships of equal capabilities. The answer would probably not be to raise the number of vessels but rather to create better, more efficient bombs.

Initiated by the Air Force Research Laboratory as a Joint Capability Technology Demonstration, QUICKSINK was intended to convert conventional unguided bombs into precision ship-killer munitions.

The idea is simple but ingenious: add a Joint Direct Attack Munition (JDAM) guidance kit to excess 2,000-pound or 500-pound bombs, and then add an advanced seeker system. Developed on a Weapon Open Systems Architecture (WOSA), this seeker integrates millimeter-wave radar with imaging infrared sensors. The radar will be able to spot ships regardless of weather, and the infrared system will lock onto warm objects, assisting the weapon in distinguishing between legitimate military targets and civilian vessels.

It enables the U.S. to quickly disable large numbers of enemy vessels—possibly including carriers—without depleting its naval resources. Stealth jets like the B-2, and eventually the B-21 Raider, can drop these from standoff distances, presenting reduced risk to aircrews and making enemy defenses harder. The modularity in seeker design also easy to adapt the system for future weapons and planes, keeping it relevant as threats and technology evolve.

What most attracts me about QUICKSINK is its price. Pricier anti-ship missiles like the AGM-158C Long Range Anti-Ship Missile (LRASM) cost around $3 million per copy, and even the aging Harpoon is $1.4 million.

In comparison, a JDAM kit is $20,000 to $30,000, and the QUICKSINK seeker now costs around $200,000—and might fall to $50,000 with mass production. That would put an entire weapon in the range of $70,000 to $250,000. At that cost, the U.S. can have deep reserves and support long, high-density operations in a manner that’s simply not possible with higher-priced missile systems.

Tactically, QUICKSINK is a significant force multiplier. It enables the U.S. to quickly disable large numbers of enemy vessels—possibly including carriers—without depleting its naval resources.

Stealth jets like the B-2, and eventually the B-21 Raider, can drop these from standoff distances, presenting reduced risk to aircrews and making enemy defenses harder. The modularity in seeker design also easy to adapt the system for future weapons and planes, keeping it relevant as threats and technology evolve.

As the Navy and Air Force develop and expand the program further, QUICKSINK is proving itself an exemplar of the way innovative engineering and frugal design can tip the balance of power at sea—without shattering the defense budget.

F-15 Eagle – The Classic Standard-Bearer

Throughout the years, having the power over the sky used to be the main thing that the army was after, a very important point which they had learned well since the Second World War. But that control is not certain anymore.

The era of the Cold War F-15 Eagle represented the classic idea of air superiority that was developed as a result of the rearming of the Soviet Union and was based on the energy-manoeuvrability theories of strategist John Boyd. Its performance in the wars, particularly with the Israeli Air Force, was impeccable, and it became a legend.

The F-15EX Eagle II that exists today continues that tradition, with searing Mach 2.5 speeds, a 60,000-foot ceiling, and the capacity to carry an astonishing 22 air-to-air missiles. Its advanced avionics and fly-by-wire systems make it deadly, but its absence of stealth has raised questions as to just how effectively it would defend itself against contemporary air defenses.

Eurofighter Typhoon – The Nimble Performer

The transformation from single-task to multi-task fighters revolutionized the landscape of air combat. Fourth-generation fighter jets such as the Eurofighter Typhoon excel in the tight battles using canard-delta wings and surgical precision of agility.

In comparison, fifth-generation fighters such as the F-35 Lightning II employ stealth, distant sensors, and effortless data-leakage to win battles before they are even fought.

German and American pilots who have flown both variants all agree—dogfighting favors the Typhoon, but for remaining unseen and providing live feed of information to the entire battlespace, the F-35 wins. What is “better” very much depends wholly upon the mission and the threats being confronted. 

S-400 Triumf – The Airspace Equalizer

State-of-the-art aircraft won’t be able to secure air dominance on their own anymore—integrated air defense systems (IADS) have altered the calculus. The S-400 and its comparably advanced counterparts can detect and attack targets at distant ranges, even penetrating stealth designs.

Stealth was created to counter enhanced ground-based threats, but not without compromises, ranging from limited weapon carriage to wear-and-tear on coatings in supersonic flight.

In parallel, innovative sensor technology can pinpoint minor engine turbulence, which could betray even stealth aircraft. No concept as yet that a single “do-everything” aircraft can do for dedicated fighters is proven, especially in close-range combat.

Buk-M1 – The Ukraine Frontline Threat

The war in Ukraine has highlighted the fact that neither side can rely on straightforward air superiority. Mobile air defense systems such as the Buk-M1 and contemporary electronic warfare systems create a “mutually denied” air zone, in which each side has to fly under perpetual threat.

The harsher truth is the complete opposite of the air dominance that is usually recalled as being performed during the 1991 Gulf War. Finnish officers Vilho Rantanen and Peter Porkka propose that this disputed territory is becoming the new norm, with mobile, networked defenses being much more difficult to annihilate than traditional fixed systems.

AGM-88 HARM – The Suppressor’s Tool

In light of these shifts, air forces are adapting their objectives. U.S. Air Force Gen. David W. Allvin has emphasized that air supremacy can no longer equate to unbroken dominance for weeks at a time.

Rather, superiority needs to be used surgically—at targeted locations and moments—to enable joint operations. Blunting enemy air defenses using systems such as the AGM-88 HARM is still essential, but newer solutions such as long-range precision strikes, unmanned systems, and space-based surveillance are increasingly appealing options.

NGAD Fighter – The Sixth-Generation Edge

In the future, the U.S. Air Force’s Next Generation Air Dominance program is a transition to flexibility and cooperation. The NGAD idea couples a manned sixth-generation fighter with a series of unmanned Collaborative Combat Aircraft (CCAs) and next-generation networking systems. These aircraft will have adaptive engines, open architecture for future upgrades, and the capability to command or direct swarms of unmanned drones. The aspiration is to prevail not by sheer brute power, but by survivability, flexibility, and transparent integration with the remainder of the force.

MQ-28 Ghost Bat – The Future Wingman

In today’s world, air superiority is not about unbroken, absolute dominance—it’s about fighting and winning in contested airspace.

Unmanned wingmen such as the MQ-28 Ghost Bat herald a future where air dominance is more of a spectrum than an on/off switch.

Technological advancements, shifts in tactics, and hard-won lessons from recent combat demonstrate that the most important thing is flexibility—shaping air power for the fight, not hoping the fight will conform to old dogma. The air domain will still be critical, but it will require new thinking and a willingness to shed old assumptions.

The Montana-class battleships embodied the last concept of the era when huge armor belts and the roar of massive naval guns gauged might-matter-of-fact. These were designed as the final evolution of American battleship construction that would go beyond the famous Iowa class to offer higher safety and more firepower. However, their ambitious project, in fact, did not progress further than designs, for a different conception of conflict had come to the fore.

A Break from the Shackles of Treaty Constraints

International naval treaties during most of the early 20th century controlled what battleships could and could not be—how much displacement, gun caliber, and armor they could have. The Montana class broke those restraints overboard. At 121 feet in beam, they were so broad they could not fit through the original Panama Canal locks, leading to plans for a new, wider set of locks to service them.

Planning commenced even prior to the entry of America into World War II, with Congress approving the first two ships in 1939. The design of Montana adopted the Navy’s traditional philosophy—maximum protection and maximum firepower—even if it cost it the speed characteristic of the Iowa class.

Armor: The Heaviest Ever on a U.S. Battleship

If they were constructed, the Montanas would have been the most armoured ships ever in the history of the U.S. Navy. Their armour was designed to brush aside the enormous 2,700-pound Mark 8 “superheavy” shells—ordnance more formidable than anything the Iowa or South Dakota class had been designed to meet.

They featured their principal armor belt, a whopping 16.1 inches in thickness, externally mounted and inclined at 19 degrees for added effective resistance. Below that, another armored belt protected against “diving shells”—armor-piercing shells with the ability to go underwater and hit beneath the waterline.

Above, the layered deck armor gave excellent protection against aerial attack. A 2.25-inch weather deck, a 7.05-inch main armor deck, and a splinter deck up to 1 inch thick together protected against plunging fire and armor-piercing bombs.

The turrets were just as effective—faces as much as 22.5 inches thick, three inches greater than the Iowas, with barbettes from 18 to 21.3 inches thick. No other American battleship design was comparable in terms of turret protection.

Built to Survive Underwater Assaults

Below the waterline, the Montana class had a four-layered torpedo defense system, with liquid-filled and air-filled compartments alternating in order to absorb and distribute explosive force from torpedoes or mines. The depth of this system was among the most well-thought-out for any battleship of the period—another testament to the philosophy of the class: to endure punishment and fight on.

The Montana class would have been a steel and firepower behemoth. But before war production priorities began turning towards aircraft carriers and fast battleships, their day had passed, leaving them as legends that never sailed.
