The new GHOST drone can fly days before it attacks.

New stealth drones are worse than the MQ-9 "Reaper" can ever be. The new GHOST drones have long-lasting capacity. They can fly even days before they start to attack. And those drones can be only the iceberg's top. The fact is that those drones can be more lethal than nobody believes. 

There is the possibility that the quite slow stealth drone can carry hypersonic missiles under or inside them. 

Those stealth systems that are connected with high-speed systems and nuclear weapons are more deadly than ever before. "GHOST will feature a hybrid-electric ducted fan propulsion system designed for stealth and long-endurance missions". (Interesting Engineering, US Air Force’s new stealth drone can fly for days before going for the kill). Hybrid electric fan systems can offer long-lasting capacity for that kind of drone. When a drone attacks, it can accelerate its speed by turning to use the regular turbojet engines. 

This kind of air combat is capable of cruise missiles. AI-controlled kamikaze drones can carry air-to-air and air-to-surface missiles. Those missiles allow the drone to reach the target more likely than if it travels without those sub-missiles. The new kamikaze drones are more versatile than traditional cruise missiles. They can also transmit data about enemy movements. There are rumors about nuclear-powered drones that can patrol in high even years.

When those drones get orders to attack they can use sub-drones. Which means they are drone carriers. Or they can use their internal warheads to destroy targets. 

An interesting possibility is to integrate the new supersonic artillery shell with the drone. Those Tiberius Sceptre shells use the ramjet engine to give them speed over Mach 3.5. There is a possibility. To install those shells into drones, helicopters or even aircraft. There is a possibility to engine a ramjet engine without an artillery socket. So. Aircraft can use the shell simply by dropping them. The helicopter can use the Sceptre grenade that is installed in the rocket. Or it can be shot from the electric launcher that allows the socket to move backward. 

That eliminates the recoil. The small size is 155 mm X 155 cm. makes that system hard to defend. And that system can act like "Super HiMARS" but it's more advanced. The system uses a hybrid GPS-inertial homing system. That is immune to the GPS jammer. Maybe, quite soon those grenades get the image-comparing homing system. Those systems allow them to aim at the target with very high accuracy. 

The artillery shell is possible to integrate with a rocket that uses RDX or some other very fast-burning propellant. That kind of thing can give that ammunition the flight speed that allows it to attack against targets that are over 140 kilometers from the drone. That range is calculated from the standing cannon. The real strike distance from the aircraft or drone is much longer. The shell will get more speed from the aircraft's speed. The new artillery shell can also be integrated into helicopters. The shell can be launched by using the plier-shaped launcher. That launcher integrates an electric arc in the grenade socket. When the propelling charge ignites the socket will go backward. And release the grenade to forward.
