A Battle Of Stealth: F-22 vs F-35
On one hand, you’ve got the world’s premier aircraft in air dominance, and on the other hand, you’ve got the most expensive weapons procurement program in world history. Even though the two jets have many things in common, both are still very different. The sole reason for the F-35 was to fill the void left by the F-22. Both hold sheer dominance over other rivals and are among the elite. The F-22 and the F-35 are 5th generation fighters, meaning they include major technologies developed during the first part of the 21st century. Other 5th generation fighters include China’s Chengdu J-20 and Russia’s Sukhoi SU-57. What details separate the two? Let’s find out.
The F-35 is no match for speed with the F-22. The F-22 can reach Mach 2.25 and can climb at a rate of 62,000 feet per minute whereas the F-35 reaches a speed of Mach 1.6 while climbing at 45,000 feet per minute. The main reason for the F-35 lacking speed is its purpose. It was not designed for speed.
The Raptor is fitted with a specially-designed AN/APG-77 radar while the F-35 is with Northrop Grumman’s latest, AN/APG-81. The system on the F-22 gives it a nearly impossible advantage – it can locate and engage the enemy without that aircraft ever even seeing the F-22 on its radar. The AN/APG-77 uses an active and electronically scanned antenna array of 2,000 transmitter/receiver modules. It can also communicate data information over a secure link and jam enemy electronics systems. The 81 model contains all the same air-to-air modes as the AN/APG-71 but also includes high-resolution mapping of the ground, an Advanced Electro-Optical Targeting System (EOTS), and a custom-designed AN/ASQ-239 Barracuda electronic warfare system. These systems, along with others, provide the F-35 with never-before-seen 360 degrees of situational awareness. The F-35 also contains multispectral imaging countermeasures. The F-22 also contains countermeasures. If heat-seeking missile locks on to an F-22 Raptor, it releases flares to misdirect the heat-seekers. If radar-guided missile locks on to an F-22 Raptor, it releases chaff (small pieces of reflective material) to scurry the radar waves.
The weaponry bay is the biggest difference between the two jets. The Raptor is designed to be raw and a bully while the F-35, is a sensible approach to things. Designed for air-to-air combat, the F-22 has a weapons bay designed accordingly. The main bay, located on the bottom of the fuselage, can hold six LAU-142/A launchers for missiles designed for enemies that are out of visual range. The F-35, designed for a more versatile engagement approach, has a unique weapons bay. The bay on the F-35 is deeper and narrower than the F-22, to carry heavier bombs mean for air-to-ground combat. The F-35 can carry any of the following air-to-ground bombs: AIM-120 AMRAAM, AIM-132 ASRAAM Brimstone anti-tank missiles, cluster munitions, Joint Direct Attack Munitions, and Paveway series of bombs. Some of these weigh up to 2,000 pounds. The heaviest bomb an F-22 can handle is 1,000 pounds. The F-35 has won this round quite convincingly.
The most obvious difference between the Raptor and the F-35 is that the F-35 can land and take off vertically. It can hover like a helicopter while the F-22 simply cannot. To be precise, the B variant of the fighter (F-35B) is the one capable of short takeoff and vertical landing (STOVL). Similar in size to the A variant, the B sacrifices about a third of the A variant’s fuel volume to accommodate the SDLF.
The Raptor and F-35 are arguably the best fighter jets ever created by the US. Both were created with one purpose in mind, to excel. If your nation’s military has either of the two, consider yourself lucky.
The B-17 Flying Fortress: A Legendary Bomber Aircraft of World War II
Let’s first listen to how the machine sounds. Enjoy!
The B-17 Flying Fortress was a critical component of the Allied forces during World War II. With its powerful engines, advanced weaponry, and remarkable durability, this bomber aircraft became an icon of American air power. Its contributions to the war effort are still felt to this day, and its legacy continues to inspire people around the world.
The B-17 Flying Fortress was designed and built by Boeing. It was a four-engine heavy bomber aircraft that first entered service in 1938. The bomber was named the “Flying Fortress” due to its powerful armament, which included multiple machine guns and cannon turrets. The aircraft could carry a heavy payload and fly at high altitudes, which made it a valuable asset for strategic bombing missions over enemy territory.
Role of B17 fortress during the war
During World War II, aircraft played a critical role in the Allied victory. It was used extensively in bombing raids over Europe, targeting strategic military and industrial targets and occupied territories. Despite the dangers of flying over enemy territory and facing intense anti-aircraft fire and enemy fighter planes, B-17 crews were determined to complete their missions. The bravery and dedication of these crews, often comprised of young men in their late teens or early twenties, helped turn the tide of the war in favor of the Allies.
How it shaped modern Warfare
The B-17 Flying Fortress was also instrumental in the development of modern air warfare tactics and technology. The lessons learned from its use in World War II helped shape the future of strategic bombing and air power and paved the way for the development of modern bomber aircraft. The bomber’s success paved the way for further advancements in aviation, and it remains an important part of aviation history today.
The aircraft was a remarkable aircraft that helped turn the tide of World War II in favor of the Allies. Its advanced design and powerful armament made it an icon of American air power, and its contributions to the war effort were critical. The legacy of the B-17 Flying Fortress serves as a reminder of the bravery and sacrifice of the men who flew and maintained these remarkable aircraft, and of the critical role they played in the defeat of tyranny and the defense of freedom.

Unveiling of the B-21 Raider: A Look at the Next-Generation Stealth Bomber
On December 2, 2022, the U.S. Air Force unveiled the B-21 Raider, its next-generation stealth bomber, during a roll-out ceremony at Northrop Grumman’s facility in Palmdale, California. While certain angles of the aircraft were off-limits, the front view provided some interesting details about the highly secretive aircraft set to replace the B-1 and B-2 fleets.
The overall shape of the B-21 Raider:
The overall shape is similar to that of the B-2, though it is likely smaller in size than previously anticipated. The leading edge of the aircraft shows a different design concept from that of the B-2. The “hawk’s-beak” profile appears to be similar to the one shown in the latest renderings and less pronounced than that of the B-2. The Raider also features a different inlet configuration, and blended conformal engine nacelles cannot be seen from the front angle. A splitter plate is visible in the inlet of the Raider.
Landing Gear and Nose Doors:
The B-21 Raider has a two-wheel main landing gear (MLG), and its MLG doors have serrated edges. The nose gear door is serrated and is not attached to the gear leg but on the right side of the bay.
The Raider’s new four-piece windscreen, similar to that of the B-2 Spirit, has a different shape for the two lateral windows. The side windows appear to be arched and narrower than the ones in the front, which are about half their height.
Color and Logo:
The color of the B-21 Raider appears to be a light gray, similar to that of the RQ-180. A small Northrop Grumman Flight test badge appears in front of the nose gear wheel bay and on the upper surface of the right-hand side wing, close to the tip. The U.S. Air Force roundel appears on the left wing.
Two new photos, taken on November 28, 2022, were released shortly after the official roll-out. One provides an elevated view of the aircraft, showing that the planform is probably not a cranked arrow wing, as some shadows in the first official images seemed to suggest. The other photo is a close-up of the B-21’s nose, showing the “hawk’s-beak” profile of the new bomber from a 3/4 point of view, which appears quite similar to that of the B-2.
The B-21 Raider’s unveiling has provided some valuable insights into the aircraft’s design, though much of it remains shrouded in secrecy. The new bomber is set to be a game-changer in the U.S. Air Force’s arsenal, with advanced stealth capabilities and a range of state-of-the-art features.

Life-Saving Technology: The F-35B’s Automatic Ejection System
The Lockheed Martin F-35 Lightning II is arguably the most advanced jet ever. With countless systems to sensors onboard, the F-35 is alone at the top and usually gets lonely at the top. The F-35B variant is the most advanced of the F-35 lineup. The F-35B type, explicitly built for the Marine Corps, could break the speed of sound while in flight and perform vertical landings on the tiniest of landing pads, much like a helicopter. As advanced as the jet is, a chance for error resulting in a crash still looms.

The jet contains an auto-eject capability system, where the jet senses the situation automatically and decides to eject the pilot itself without the pilot having to think about whether or not it is safe to do so. The seat installed is a Martin-Baker US16E type seat which delivers a previously unseen level of well-balanced optimization across critical performance factors such as safe terrain clearance limits, physiological loading limits, pilot boarding mass, and anthropometric accommodation ranges to completely satisfy the F-35 Escape System criteria.
All versions of the F-35 aircraft will share the US16E. The sole Joint Strike Fighter model with this technology is the F-35B, which is also the first American aircraft of any sort to have this capacity.
It is unclear exactly how or by what criteria the auto-eject system judges that the aircraft is not within the pilot’s control and initiates the ejection procedure. Its precise condition on the F-35B fleet is also unknown. It is well known that the US16E seats on every F-35 type are connected to the flying systems in some other way to prevent the pilot from ejecting in dangerous circumstances. It’s interesting to note that the Cold War-era Soviet Yak-38 and Yak-141 jump planes had engine configurations more akin to the F-35B.
However, both featured vertically mounted jet engines rather than lift fans and auto-eject systems. The F-35B’s inclusion of auto-eject is directly related to how challenging the aircraft’s vertical takeoff and landing is. In the hover mode, the jet’s Pratt & Whitney F135 engine’s power is directed downward through an articulating exhaust nozzle, and a large fan is mounted vertically in the center of the fuselage to create lift. The engine directly powers the lift fan through a big drive shaft connected to a carbon clutch.
The B version of the F-35 is significantly distinct from the other two primary variants. It differs from them all in so many ways that it has affected every aspect of its essential construction.
