Hell Holes 3 – Background


Demon Plague UAV

Hero 30 UAVFor the purposes of the book, I needed a small, man-portable Unmanned Aerial Vehicle (UAV) to spread the demon plague on the demon homeworld. To avoid attack by gargoyles, it needed to be fast and relatively quiet (electric motor). It also needed to be fast enough and have sufficient range to rapidly avoid the nuclear blast zone, with a military on-board control system to survive the bomb’s electromagnetic pulse (EMP).

For these reasons, I selected the Israeli Uvision Hero-30. The wings and tail fins fold lengthwise so that it fits into a rectangular canister launcher. The UAV weighs 3 kg (6.2 pounds) and can carry a payload of .5 kg (1.1 pounds). It is 80 cm (2.5 feet long) and has a wingspan of 70 cm (2.25 feet) when its four wings are unfolded. It has a cruising speed of 100 knots (115 mph) and a maximum speed of 160 knots (184 mph). It has an endurance of 45 minutes. It is typically controlled via a communication link with a range of 40 km (25 miles). It is man-portable in a tall bulky backpack that carries 3 launch canisters. The actual UAV is a loitering munition (flying bomb), but was modified in the book to carry and distribute the plague virus while flying a pre-programmed flight plan.


B-61 Variable-Yield Thermonuclear Bomb

To totally destroy the portal complex used by the demons to invade Earth, I needed a nuclear bomb that was reasonably available, flexible (large enough yield to guarantee destruction, small enough so that the six plague UAVs could exit the blast zone before the bomb explodes), and sufficiently portable to be taken down into a hell hole and through the associated portal to Hell. The B-61 model 10 variable-yield thermonuclear bomb set to 10 kiloton yield fit the bill, assuming that you remove all of the unnecessary parts.

Four Major Components of B-61 Variable-Yield Thermonuclear Bomb As you can see, the bomb is made of four major subsystems. From left to right, they are the tail assembly, the section holding the preflight controller, the section containing the warhead, and the nose cone containing the radar and associated electronics.

In the book, only the middle two components were taken through the portal in order to make the bomb as small as possible (approximately 5 feet long, 13 inches in diameter, and TBD pounds). Steel disks are welded to the two ends of the resulting bomb to prevent demon access before the bomb explodes.

B-61 Preflight ControllerGround-based personnel set various control parameters by using the preflight controller, which they access via an access panel on the side of the bomb. As shown in the figure, the preflight controller has 9 dials, 2 sockets, and a T-handle. The top socket is a Permissive Action Link (PAL) connector that prevents unauthorized use, while the bottom socket holds a “strike enable” plug which must be inserted in order to complete critical safety, arming, and firing circuits. Three dials are used to enter numerical codes, whereas the remaining six dials are used to set such parameters as explosive yield (option dial), time delay, blast altitude, and mode (such as “command disable”). The T-handle is used to permanently disable the bomb by frying critical circuits.

In the book, parts of the preflight controller are reprogrammed to enable the air-dropped bomb to operate as a Earth-saving time bomb.
