Super Chief

The twelve Kirov-class airships flew slowly from a distance in a seemingly slow posture. They had not yet reached the sky above Boston. All the American troops and the sailors of the joint fleet who saw this thing had their faces. All showed an expression of looking at God.

　　 The speed of the Kirov-class airship is not slow, even if it is flying against the wind, it can reach a speed of 15 kilometers per hour steadily. Although this speed is not comparable to the speed of a galloping horse, don’t forget that the airship can fly continuously in the air. As long as the small steam engine that provides the power does not cause problems and the fuel medium is sufficient, the rigid airship can theoretically cross the Atlantic directly. Even a trip around the world.

　　Of course, this Kirov-class airship of the Yanhuang tribe is still unable to sail across the ocean. However, if the airship is made bigger, the buoyancy is doubled, and the steam engine is replaced by an internal combustion engine, then it will be no problem to sail across the ocean.

The Kirov-class airship does not look big from a distance, but once it flies overhead, the shock is not a joke, even if the airship's flying height is always maintained at 800 meters or more, it can be used as a piece of twelve airships. When flying, it can only be described as covering the sky and the sun.

　　The Kirov-class airship has a plump spindle shape as a whole, with a diameter of more than 18 meters at the thickest part and a length of more than 90 meters. In other words, the size of a Kirov-class airship is about the same as a Carlos-class battleship.

　　 Compared with the Kirov-class airship, the previous hot air balloon was an absolute younger brother...

　　 Such a big lump flying in the air, even if it is more than 800 meters above the ground, it still looks very big on the ground.

　　Because the airbags of the airship are filled with flammable and explosive hydrogen, for the sake of safety, the altitude of the airship cannot be lower than 800 meters when it is flying steadily, and it cannot take off in a thunderstorm...

　　 The cost of such a Kirov-class airship is quite high, even if it is not comparable to a Carlos-class battleship, it is not much different.

　　 Therefore, in the past six or seven years, the Yanhuang tribe has almost built twelve Carlos-class airships with the help of the entire clan. This thing and the warship sailing in the sea are both Shi Xiong's heart, and there is no room for loss.

　　 When the Kirov-class airship flew over Boston, the total offensive was completely launched.

The first attack was the second division’s divisional artillery regiment. The 105mm cannon and 76mm cannon fired the first round of salvos. Well, it’s worth mentioning that there are four more divisional artillery regiments in the second division. 122mm cannon.

　　 After arduous research and development, especially the arduous efforts of scientists from the Yanhuang Institute of Science and Technology and smelter engineers, the Yanhuang tribe already possesses qualified steel that can build a 122mm cannon barrel.

　　At the beginning of the year, the Shangjing Military Factory had already built twenty 122mm cannons. Now the divisional artillery regiments of the five divisions attacking the American Federation have four guns each.

　　 This time the total attack on Boston was the first time the 122mm cannon fired in actual combat.

　　 Even if they are five or six kilometers away, Abbasnot and the others can feel the power of a group volley. The sound of the rumble of gunfire and the louder explosions are enough to prove how fierce the firepower of the team that is attacking Boston is.

　　 And the chubby gentleman standing on the deck of the Xiongxiang turned pale in fright.

　　 If he hadn't arrived at the dock at the last moment and boarded the Bear Roe, he would now be covered by this terrifying artillery just like his men.

If the shooting of the gun regiment of the second division of the Grim Bear Army can definitely be described as horror, then when the Kirov-class airships flying on the day began to "lay eggs", almost no one knew how to describe this "flying devil". "It's horrible.

　　 Boston at this time was actually not that big, far not as big as shown on the map of later generations.

　　Boston is built on a peninsula, connected to the mainland through a narrow isthmus, and surrounded by the mouth of Massachusetts Bay and Back Bay-Charles River. The early European immigrants in Boston originally named the City of Three Hills based on the three small hills here.

　　Before the nineteenth century, the residents of Boston could only expand the area of ​​Boston a little bit through small reclamation projects. But beginning in the nineteenth century, Boston carried out a huge renovation project of "cutting mountains and filling the sea" to accelerate the expansion of Boston's area. For example, in 1807, the top of Beacon Hill was used to fill a 50-acre pond, which is equivalent to about 20 hectares. Later, the filled-up pond formed the Haymarket Square today.

　　 But now, Boston is really small.

If the core area of ​​Boston, that is, the walls of the Boston Fortress, can withstand the firing of the 2nd Division’s artillery regiment, then when the Kirov-class airship flew overhead, the battle completely turned into a dimensionality reduction strike. .

The aerial bombs weighing more than 30 kilograms and the warhead with a charge of up to eight kilograms were like laying eggs. They were continuously dropped by the Grizzly Army Air Force soldiers in the cabin of the airship through sights and bombers, and then dropped. Air bombs do not produce sonic booms and screams like artillery shells, but once this kind of aerial bomb that does not make any sound in the air hits the ground, then you will understand what the scene of the ground shaking.

　　The total load capacity of the Kirov-class airship can reach four tons. After deducting the weight of the fuel medium and the weight of six soldiers, a Kirov-class airship can carry about 2.4 tons of aerial bombs, which is 80!

And once this kind of aerial bomb filled with eight kilograms of high-explosive explosives explodes, unless you hide in a solid underground fortification, within a radius of 20 meters from the explosion point, absolutely no one can survive, even if You can’t hide in a sturdy house~www.wuxiaspot.com~ The fragments of an aerial bomb may not kill you, but the shock wave can shatter all your internal organs alive!

　　 If there is no protection, soft targets within a forty-five-meter radius around the burst point will be killed. Of course, the fragmentation radius of aerial bombs can be more than 45 meters. If you are unlucky enough, even if you stand a hundred meters away without any protection, then you have a high probability of being killed by fragments!

　　 In contrast, let alone the 105 heavy artillery of the second division's artillery regiment, even the 122 heavy artillery that was just developed, is a younger brother in front of this kind of aerial bombardment!

　　 The most important thing is that this thing is hit in the air. In this era, this kind of aerial strike is an out-and-out dimensionality reduction strike, and you don’t even have a place to hide.

Whenever an aerial bomb falls and explodes, the ground will move with it, and then centered on the explosion point, a huge shock wave will destroy all houses within a radius of ten meters, and fragments exceeding three times the speed of sound will kill within the range. All the standing people are harvested, and finally a small black mushroom cloud will rise with the explosion point as the center...
