New stealth systems are required for a new type of warfare.

“The J-31 differs from the F-35 in that it has two engines, which in turn reduces its area ruling, making for more efficient supersonic flight, including future supercruise once the J-31 obtains more powerful engines. Hunter Chen” (Popular mechanics)

Invisibility cloaks. Or. Invisibility fabrics are tools. Whose purpose is to improve servicemen's survivability. Those systems are used in Libya and some other modern conflicts. This system also helped the F-15 crew members hide when their plane was shot down in Iran.  Snipers. And other operators who want to hide from their enemies are almost certainly using those things. The invisibility cloak. Can be connected. 

With new types of recon boats, cars,  satellites, and some helicopters. The big problem with those systems is that they cannot hide objects from radar or infrared. The important thing today is invisibility. And. The invisibility cloak can offer visual invisibility for users. This system can make vehicles invisible, but the big problem is: how to install it on high-speed jets. 

In normal scenarios. The stealth material absorbs radar signals. This means that the stealth material conducts energy to the battery. Or it transforms it into heat. Then that material must conduct that heat somewhere. No material can absorb energy forever. There is a limit. After. The material reaches that energy limit.  The radar-absorbing material (RAM) will be broken. 

It is always possible that some stealth fighter gets hit in enemy airspace. This can cause a situation. That allows the enemy to hack the material. And this means that. No part of the stealth airplane must fall into hostile hands. 

If. The material turns hot. That heat makes the aircraft visible. In. infrared (IIR) imaging sensors.  That technology uses machine vision and AI components to detect targets. 

if. The EMP weapon is targeted. At. The area. It can destroy the electronics that those systems use. This is the problem with high-tech systems. The EMP is a high-power radio signal. That. The radio transmitter can create it. It uses high-power impulse capacitors. The EMP can terminate all electronics. And make those kinds of invisibility cloaks malfunction. The EMP can also destroy electronics in drone swarms. The high-power EMP weapon can also destroy electronics in aircraft, cars, boats, and everywhere else. After the EMP strikes, the target seems unharmed. But all computers are destroyed. Because. Of a high-voltage spike. The EMP impulse. Can be sent from high-power radars. So. The EMP weapon can be a radar with extremely high transmission power. 

The new quantum stealth systems. They can make all electromagnetic waves slide over the surface. If. That surface cannot be impacted by electromagnetic radiation. That radiation cannot transport energy into the aircraft’s structure. So. That means. Quantum stealth should protect against lasers. And.  Other directed energy weapons. The ability. To turn light away from the target. It makes it invisible. But. This ability. Like counter-radiation. It makes it possible. To. Turn the laser beams away. This requires a counter laser beam. That has the same wavelength. With. Attacking lasers. The loyal wingman drone can block the laser beam. That destroys the loyal wingman drone. But it leaves the aircraft time to point its own weapon at the laser. This means that. The last ultimate solution. It is replaced. By. Another ultimate solution. And. In the world of military. There is an endless race between the ultimate attacker and the ultimate defender. 

“By bending light around an object, the science of transformation optics could enable the first working 3D cloaking device. A new advance in metalenses, if successfully applied, could extend a cloak to the visible light portion of the spectrum, enabling the first true "invisibility cloak.

The cloak can be covered. Using carbonite class. That class can offer a hard shell for those vehicles. Carbonite class is the hardest material for spacecraft. This kind of material can form a new type of armour. The carbonite class can protect the invisibility cloak. The big problem is that. The material can be seen on radar. The fact is that. Most of the cheap drones use regular CCD cameras. And that kind of invisibility cloak can protect against regular CCD cameras. But the problem is that. The drone swarm can involve different types of drones. Each drone can have different types of cameras. This makes them hard to feint. 

New quantum technologies are making traditional stealth materials useless. Modern missiles use artificial intelligence and multi-sensor homing systems. This means. They are immune to traditional infrared jamming systems, including torches. The jammer systems and other active tools are effective. But the problem is the active radio transmission. Anti-radiation missiles can turn those jammers against their users. An infrared jammer also sends IR radiation. That radiation can jam traditional IR-homing missiles. Optical fire control with laser and microwave systems can use those jammers as targets. 

Things like plasma-stealths are under development. Plasma stealth is a tool that can protect aircraft against radar. The big problem is that. Plasma denies radio waves from traveling through it in both directions. This effect causes radio silence. When. Spacecraft arrive in the atmosphere. Friction raises its temperature. And it turns the air around it into plasma. This plasma layer denies radio communication. Through. It. This plasma layer makes it hard to develop hypersonic aircraft. And it makes it hard to develop plasma stealth. 

The answer can be lidar. Laser radars can see through this layer. Hypersonic cruise systems can use AI-boosted lidar. And. Optical sensor systems can see targets. Another possibility is this. The aircraft uses loyal wingman-type drones to drop. Other drones to operational areas. Those drones can mark targets. That is one version os the new types of systems. The hypersonic drone travels over the target area. It drops those marker drones. And then the next wave sends weapons to targets.
