Beyond the F-35: Air Force and Navy already working on 6th generation fighter

Fighter jets in 20-years may likely contain the next-generation of stealth technology, electronic warfare, sophisticated computer processing and algorithms, increased autonomy, hypersonic weapons and so-called "smart-skins" where sensors are built into the side of the aircraft itself.


Some of these characteristics may have been on display earlier this year when Northrop Grumman's SuperBowl AD revealed a flashy first look at its rendering of a new 6th-generation fighter jet. Northrop is one of a number of major defense industry manufacturers who will bid for a contract to build the new plane - when the time is right.

The new aircraft, engineered to succeed the 5th-generation F-35 Joint Strike Fighter and explode onto the scene by the mid 2030s, is now in the earliest stages of conceptual development with the Air Force and Navy. The two services are now working together on early conceptual discussions about the types of technologies and capabilities the aircraft will contain. While the Air Force has not yet identified a platform for the new aircraft.

The Navy's new aircraft will, at least in part, replace the existing inventory of F/A-18 Super Hornets which will start to retire by 2035, Navy officials said.

The Navy vision for a future carrier air wing in 2040 and beyond is comprised of the carrier-launched variant of the Joint Strike Fighter, the F-35C, and legacy aircraft such as the EA-18G Growler electronic jamming aircraft.

Also, around this time is when Navy planners envision its 6th generation aircraft to be ready, an aircraft which will likely be engineered for both manned and unmanned missions.

Technologies are rapidly advancing in coatings, electromagnetic spectrum issues, maneuvering, superiority in sensing the battlespace, communications and data links, Navy leaders have said.

Navy officials also add that the Navy is likely to develop new carrier-launched unmanned air vehicles in coming years as well.

Analysts have speculated that as 6th generation developers seek to engineer a sixth-generation aircraft, they will likely explore a range of next-generation technologies such as maximum sensor connectivity, super cruise ability and an aircraft with electronically configured "smart skins."

Maximum connectivity would mean massively increased communications and sensor technology such as having an ability to achieve real-time connectivity with satellites, other aircraft and anything that could provide relevant battlefieldinformation.Thenew aircraft might also seek to develop the ability to fire hypersonic weapons, however such a development would hinge upon successful progress with yet-to-be-proven technologies such as scramjets traveling at hypersonic speeds. Some tests of early renderings of this technology have been tested successfully and yet other attempts have failed.

Super cruise technology would enable the new fighter jet to cruise at supersonic speeds without needing afterburner, analysts have explained.

Smart aircraft skins would involve dispersing certain technologies or sensors across the fuselage and further integrating them into the aircraft itself, using next-generation computer algorithms to organize and display information for the pilot.

Smart skins with distributed electronics means that instead of having systems mounted on the aircraft, you would have apertures integrated on the skin of the aircraft, analysts have said.

This could reduce drag, increase speed and maneuverability while increasing the technological ability of the sensors.

It is also possible that the new 6th-generation fighter could use advanced, futuristic stealth technology able to enable newer, more capable air defenses. The air defenses of potential adversaries are increasingly using faster computing processing power and are better networked together, more digital, able to detect a wider range of frequencies and able to detect stealthy aircraft at farther distances.

The new 6th-generation fighter will also likely fire lasers and have the ability to launch offensive electronic attacks.

The truth about cell phones in Basic Training

Thank god you got out when you did! The moment you received your DD-214, it was officially an end of an era. Hopefully, your branch won't fall victim like all those other, weaker branches did. It's Lord of the Flies in here.

New recruits are arriving in droves and they're pulling out their cell phones to record themselves talking back to their drill sergeants. If the drill sergeants have a problem with it, they whip out their stress cards, go back to eating their Tide Pods, and continue listening to their music (which, coincidentally, has gotten progressively worse since your generation, too).

5 reasons your troops are more important than promotion

If there's one complaint common across the military, it's that commanders too often care more about their careers than the well-being of their troops. It's problematic when higher-ups are willing to put lower enlisted through hell if it means they look good at the end of the day.

These high-tech glasses could change how sailors train

Training has evolved over the years but the core elements have always remained the same. There's an instructor and a bunch of students. They go over material, both in theory and in practice, mastering the skills required by the job. But no matter how good the teacher, students will always need a refresher from time to time. So, that means it's time to go back to school — or does it?

Now, mixed-reality technology — including smart glasses — could change the way sailors learn the skills they need to serve.

6 US conflicts that would (probably) make terrible video games

When developers set out to make video games, their focus should always primarily be on crafting a fun and engaging experience. Oftentimes, you'll see video games set far in the future so that developers can place an arsenal of advanced, sci-fi weaponry in the hands of the player — because it's fun. Other times, they'll take cues from real wars and toss the player directly into the heat of a historical battle — because that's fun, too.

How to start a fire with only one hand

Heading out into the wilderness for a camping trip is exhilarating and refreshing. Starting a campfire and roasting some marshmallows under the stars is a great way to get in touch with Mother Nature. Although the idea of spending a night in the great outdoors sounds incredible, campers should always remember to bring specific tools and learn important survival skills in the event they sustain an injury and help is far, far away.

It gets cold out there at night, so it's important to know the basics of starting a fire to keep warm — even in the dire circumstance that you've been injured. Do you know how to start a fire with just one hand? You never know — this skill might just save your life.
