F-22 vs. F-23: Why the Ultimate Stealth Air Duel Won't Happen

“Interestingly the YF-22 and YF-23 had exactly the same trimmed AoA of 60°. The YF-23 could do it without thrust vectoring. Those V-tails were very powerful especially when coupled to an unstable airframe,” said one source who is intimately familiar with both the YF-23 and the Raptor. “The YF-22 probably had an advantage at very, very low airspeeds but neither company had enough time to investigate dynamic low speed, high AOA maneuvering. This was a good example of how a competition needs to consider the PR value of flight test events.

China Claims to Have Developed a Radical New Stealth Technology for Its Submarines

Thus, if the Chinese have managed to successfully develop a rim-driven pumpjet propulsor that works in a real world operational setting, it would be a significant development. It would mean that the PLAN is making genuine progress in developing novel submarine technologies and that it is starting to catch up. But there is more to a submarine’s acoustical stealth than just the propulsion system, and it will take time and a lot of trial and error before the PLAN can match or exceed American capabilities in the undersea domain.

Bloodbaths: These Are the 5 Most Horrific Wars in All of History

Unlike World War I, World War II was a truly global war with much of the fighting taking place in Asia and the Pacific. The Soviet Union lost an estimated 27 million military personnel and civilians, making it by far the country with the highest death toll. China is thought to have suffered 20 million deaths, Germany 6-7 million, and Japan roughly 2.5 to 3.2 million. The United States was fortunate, losing approximately 420,000, all but 10,000 military deaths.

All wars are awful. Some wars are much, much more awful than others.

YF-23: The Stealth Super Plane the U.S. Air Force Almost Built Instead of the F-22

As is the case with the X-32, the YF-23 never faced the most dramatic problems to afflict the F-22 Raptor. It never experienced cost overruns, technology failures, software snafus, or pilot-killing respiratory issues. Those problems, which regularly afflict new defense projects (in fairness, the pilot suffocation is largely idiosyncratic to the Raptor) were consequential. In context of the broader demands of the War on Terror, Secretary of Defense Robert Gates curtailed the F-22 production run at 187 operational aircraft, just as the fighter was working through its teething troubles.

Revealed: Japan's Military Wish List to Wage a War Against North Korea

Once Japanese ISR assets detect North Korean mobile launchers in the wild, they will have to be quickly destroyed. The urgency of the antimissile campaign means that North Korean air defenses may not be adequately suppressed, making missions over the country risky. MQ-9 Reaper medium-altitude long-endurance drones could fly such missions instead, taking off from Japan loaded with fuel and munitions and flying long patrols over North Korea.

Get Ready, North Korea: F-35s Can Track Ballistic Missiles

Described as multi-function array technology, the DAS system uses automated computer algorithms to organize and integrate target-relevant data from missile warning systems, radar, night vision and other long-range sensors; the array is able to track a BMD target from the air at distances up to 800 nautical miles. Such a technology, quite naturally, enables a wider sensor field with which to identify and track attacking missiles.
