Chapter 455: Chapter 221 New Function Chapter 455: Chapter 221 New Function After the drone upgrade, it had three types of powerful missiles at its disposal, but apart from these three types of missiles, another weapon for ground attack – a super bomb – appeared in the drone's weapon storage, the GBU-28 laser-guided bomb.

The GBU-28 laser-guided bomb is a smart subterranean super bomb used by the US Forces, weighing 2.3 tons. Its explosive power upon detonation is earth-shattering. Deployed from high altitude by the drone, it is guided by quantum radar and then strikes targets beneath the surface.

This massive bomb falls from high altitude, carrying significant kinetic energy. It can penetrate at least three layers of reinforced concrete or steel plates. After system enhancement, the GBU-28 laser-guided bomb not only has increased power but also new functions. Inside the bomb body are multi-stage fuzes; upon hitting the ground, it burrows to a certain depth where Fuze A detonates, creating a hole for the bomb to continue burrowing; encountering concrete structures, Fuze B detonates, breaking through and burrowing further; upon reaching steel-reinforced structures, Fuze C detonates; only after penetrating the steel does the bomb explode within the bunker, massively damaging the underground target.

The use of AGM-114 anti-tank missiles and AIM-120 air-to-air missiles allows the drone to maintain a formidable air-combat capability, characteristic of fighter jets. While the presence of AGM-129 stealth cruise missiles and GBU-28 laser-guided bombs endows the drone with a fearsome ground bombing and attack capability, truly displaying the B-2 strategic bomber's destructive prowess.

Aside from the three types of missiles and a subterranean bomb, the drone's weapon system also includes another kind of weapon – the 30mm Vulcan Gun, two in total. They are located on either side beneath the drone, retracted into the belly to ensure the drone's stealth capability and avoid detection by enemy radar. Only when an aerial cannon attack is needed do the Vulcan Guns extend from the belly to engage in combat.

Just like before, each Vulcan Gun has an ammunition supply of 1,800 rounds, with a combined total of 3,600 rounds for both guns. The ammunition types include armor-piercing rounds, high-explosive rounds, and incendiary rounds. During an attack, the type of ammunition can be switched according to the actual needs, but the total amount is controlled. Each Vulcan Gun can only fire a maximum of 1,800 cannon rounds, allowing for a combined firing capacity of 3,600 cannon rounds from both guns.

Equipped with these two powerful Vulcan Guns, combined with the fast scanning and locking ability of the quantum radar, and the precise control of the auxiliary brain, the drone still possesses a potent close-range air combat capability. It can still destroy various inbound missiles, serving as the drone's most crucial and cost-effective anti-missile method.

Among its special abilities, the drone retained its vertical take-off and landing capabilities as well as the ability to enter the water. In addition, the drone has acquired two new functions – one is radar stealth, and the other is underground traversal. Radar stealth renders the drone undetectable by enemy radars, achieving a stealth effect. As for underground traversal, as the name implies, it enables the drone to operate beneath the surface, an exceedingly powerful and practical ability.

Last year, when Yan Fei encountered a subterranean submarine capable of underground traversal beneath the Louvre Museum in France, he was highly interested in it. Unfortunately, that submarine was destroyed by Yan Fei and later washed away by the floodwaters of the Seine River. At that time, he was very keen on having the ability to traverse underground himself; it would have allowed him to complete many tasks unnoticed, eliminating the need for him to take risks in person. Yan Fei had thought this ability would forever be beyond his reach, but to his surprise, his drone had acquired an even more amazing underground traversal capability after this upgrade.

The so-called underground traversal ability means that when the drone lands on the surface and activates its underground burrowing mode, it undergoes a significant transformation, taking on a shape suitable for underground navigation. After the transformation, the appearance of the drone changes drastically, no longer resembling the B-2 Stealth Bomber. Its front is a huge, sharp, rapidly rotating drill bit capable of cutting through steel like mud, and can quickly excavate dirt and rock. Its fuselage is a streamlined cylindrical shape with minimal friction resistance, and beneath it are two massive tractor tracks.

During underground traversal, the drone relies on the two giant tractor tracks to provide powerful propulsion. As the tracks move, the drone advances, with the massive drill bit in front rotating rapidly to break through the earth and rocks ahead. The soil excavated by the drills is carried back by the tracks, creating enough space for the drone to move forward.

Another miraculous aspect of the drone during underground traversal is the cockpit's atmosphere; it doesn't suffer from oxygen deficiency. This means that as long as the drone has enough energy points and can withstand the immense pressure underground, it can continue to traverse indefinitely. If the energy points are depleted, the drone will be stuck underground, immobilized.
