Doomsday: I Build a Space Fleet

Chapter 197 Air Support Unit Update

On the 8th day after landing on the shallows, the clearing work at the airport located north of the forward base was successfully completed, and three sets of small floating wind power generation devices were also transported to the military factory in the south.

After their research, Lorraine, Platinum, Ouyang, and Nian identified two types of artillery firepower for long-range support.

The prototype of the first twin-mounted 60mm self-propelled rapid-fire mortar was the export version of the twin-mounted 80mm self-propelled mortar.

欧阳年和洛林对其结构进行了优化，将其原先长8米、宽3.2米、高三米的车体缩小至6.2米长、2.8米宽、2.7米高，与12吨级的6轮步战车体积相仿。

The original muzzle loading structure was changed to breech loading, and the firing technology was changed from gunpowder firing to electromagnetic coil firing. The maximum range is 6 kilometers, and the shell's destructive effect is the same as that of a conventional 80mm mortar.

The two cannons are spaced 70 centimeters apart and fire alternately, with a burst rate of fire of 240 rounds per minute and a maximum rate of fire of 160 rounds per minute.

The vehicle's turret can rotate 360 ​​degrees, and the gun's elevation angle ranges from -3 degrees to 85 degrees. When using direct fire, the maximum range is reduced to 1200 meters, which can effectively kill soft targets or lightly armored targets.

As a fire support unit for platoon-level combat units, this vehicle can move and deploy quickly. Each vehicle can carry 180 rounds of ammunition and has a maximum endurance of 12 hours.

The other is the PCLD-12 130mm vehicle-mounted electromagnetic railgun, which is based on a 155mm vehicle-mounted howitzer.

However, the vehicle does not use a fully electric propulsion system, but instead adopts range-extending technology, with its range-extending power being a small gas turbine equipped with a waste heat recovery device.

In order not to affect the ammunition carrying capacity, part of the prototype gun's cockpit space was replaced with electronic systems and engine equipment. Thanks to the adoption of electromagnetic gun technology, the gun's ammunition carrying capacity reached a terrifying 80 rounds.

At maximum firing rate, the maximum range for firing conventional shells reaches 120 kilometers.

If this type of artillery is equipped with specially modified terminally guided munitions and guided by a combination of infrared and laser detection, it can accurately strike targets from 200 kilometers away.

Since the vehicle will be used in conjunction with airborne and rapid reaction forces, Lorraine and Ouyang Nian minimized the size and weight of the vehicle-mounted howitzer while maximizing its range.

Finally, they obtained a truck-mounted gun with a combat weight of 24.3 tons (28.3 tons when fully loaded), a length of 6.2 meters, a width of 3 meters, and a 6×6 chassis, which was manually loaded.

Bai Jin was somewhat shocked to see the vehicle-mounted 130mm cannon that Ouyang Nian and Luo Lin had put together. With only two engineering robots, the cannon's rate of fire was actually eight rounds per minute.

Moreover, the vehicle can reach a maximum speed of 110 kilometers per hour when driving on paved roads, and can maintain a maximum speed of 80 kilometers per hour even when driving on unpaved roads.

Bai Jin stood there stunned for a moment, holding the data sheet. She now deeply understood what it meant for some people to be born to do this kind of work.

Lorraine grinned mischievously, patted Platinum on the shoulder, and continued to add some shocking information.

"Since we currently lack an aerial vehicle capable of transporting this truck-mounted artillery, the production of super-heavy transport helicopters and medium-sized unmanned transport aircraft is proceeding simultaneously."

Bai Jin stared blankly at Ouyang Nian, who had faint dark circles under his eyes.

"You're not going to tell me we have a transport helicopter capable of lifting up to 30 tons?"

At this point, Platinum's language system was already somewhat chaotic.

Ouyang Nian shook her head, then glared fiercely at Luo Lin before calming Bai Jin, whose emotions were in great turmoil.

"We only found a medium-sized tactical transport aircraft that meets the requirements in the database. The unmanned modification has also been completed, and it should be conducting test flights over Hongfeng Island now."

Lorraine smiled after being glared at by Ouyang Nian, left the driver's seat, put on her power armor, and arrived at Ethan's camp in the light transport vehicle that came with it.

On the flagship, after Ouyang Nian and the others calmed down, they retrieved from the data panel a vertical takeoff and landing aircraft that clearly belonged to the same series as the one they found in the database.

After taking the data panel, Platinum carefully examined the data of these vertical takeoff and landing aircraft.

The layout of these vertical takeoff and landing aircraft is different from the single-engine, single-rotor helicopters with tail rotors that Platinum had previously been familiar with. She could see some traces of previous foreign military high-speed transport helicopter development programs in them.

The first project is a multi-purpose tactical utility helicopter. This aircraft has a ducted fan with a diameter of 1.5 meters installed on each side of the cabin, and a pair of small V-shaped tail fins at the rear of the fuselage.

A comprehensive electro-optical turret is mounted under the nose of the aircraft. There are small racks on the left and right sides of the cockpit facing rear, which can be used to install small detection devices or weapons. Both the left and right hatches behind the cockpit are equipped with chassis racks.

Because the entire machine uses a large amount of composite materials, it can still withstand direct fire from 7.62mm full-power rounds.

The airframe has an empty weight of 4325 kg, a maximum takeoff weight of 11560 kg, a maximum range of 3480 km, and a combat radius of 1054 km.

Relying on two ducted fans that can rotate flexibly, this helicopter can reach a maximum speed of 413 kilometers per hour and can perform more complex maneuvers when facing danger.

The second project is similar, but it is a heavy attack helicopter. The aircraft's shape and layout have been adjusted, and its maximum takeoff weight has reached 13.2 tons.

The power system was moved slightly upwards, and the jet nozzles and air intakes of the two turboprop engines were adjusted. The fuselage was enclosed, the front window area was reduced, and the tail section of the fuselage featured a pair of H-shaped tail fins.

The position of the photoelectric turret was moved back 40 centimeters, and a millimeter-wave radar was installed in its original location.

机身中部上加装了两个巨大的短挂架，单侧短挂架可以悬挂4个大型火箭巢和一个4联装飞弹挂架，一共可以携带152枚70毫米无制导火箭弹或是56枚140毫米智能火箭弹。

There are two small pylons on both sides of the cockpit, with a twin-mounted air-to-air missile launcher on each end, and a 20mm cannon that can rotate freely mounted on the bottom of each pylon.

Both aircraft have upgraded versions, but their respective improvement directions are different.

The improved version of the first project was equipped with two more powerful and economical turboprop engines, and the size of the two ducted fans was also increased.

The overall layout of the aircraft was also slightly adjusted, replacing the original V-tail with a pair of horizontal tails and two slightly inward-sloping vertical tails.
