The project team did mention new fighter jets. Without considering electronics, the upper limit of monoplanes is higher than biplanes. However, the final entry into the one-year plan was still primarily modification schemes.

This decision was made by Wu Yuanzhang, the technical director.

Roland also learned a new concept from the meeting: time efficiency.

That is, any engineered product on an assembly line will increase its production efficiency as time goes on, even if it itself does not change. This phenomenon will occur spontaneously. The reason is that processing is a skill, and workers will gradually become familiar with the operation of the production line, including the interaction between people and machines, and the interaction between people. This has nothing to do with literacy, but more with the inherent nature of laziness. Everyone will actively look for the easiest way to complete the task, and even improve the irrationalities in the process.

Therefore, the production speed and qualification rate of an industrial product in the later stage are not only much higher than in the early stage, but also the cost will be much lower, which is the reason.

If the Sky Knight is to form a scale as soon as possible, then the production line that has been running with great difficulty should be temporarily maintained, which will help workers familiarize themselves with the processing and operation procedures of the machinery, so as not to let the equipment drag down the war.

The improvement direction of Tianhuo primarily focuses on airframe modification, more powerful engines, and new weapon systems.

The first point goes without saying. Tianhuo is completely a product of Roland's experience and exploration based on the antique machine drawings in his dreams. Although aerodynamic layout is not an important issue for biplanes with a top speed of no more than 150 kilometers per hour, it does not mean that it has no benefits. On the contrary, with the support of wind tunnels and simulation technology, modifying airfoils and the like is the least expensive and easiest part to improve.

The engine is obviously also a top priority - as the saying goes, as long as the power is sufficient, a brick can also be super-maneuverable. Once the power is up, other improvements will be easy. However, even the most basic piston engine must take into account the low technical level after the doomsday, as well as durability and performance, so designing it is not so easy. It is said that the relevant team came up with seven or eight trial schemes in one go, and it will take some time to determine which engine to choose as the optimal solution.

There are not so many concerns about the new weapon system.

To put it bluntly, it is not technically difficult. The military has a bunch of mature and eliminated plans, such as 20mm machine guns, detachable aerial bomb racks, and so on. What to install and how to install it depends on the first two improvements, which are contents that can be added at any time.

According to the technical indicators given by the project team, the Type II biplane will have a cruising speed of 250 kilometers per hour, can carry two 100 kg auxiliary fuel tanks, a range of more than 1,000 kilometers, and both climbing speed and ceiling will be much higher than Tianhuo.

This means that the improved biplane can rush from the rear to the front line within a day, or fly directly from the front line to the Great Rift Valley on the spine of the continent. Considering the rugged terrain at the source of the Endless Mountains, ordinary troops have difficulty passing through, this parameter undoubtedly has extremely important significance.

Finally, there is the bomber.

It is the most expensive and most controversial project in all plans.

It took half a day just to discuss whether such a dedicated aircraft was needed to deal with degenerate demons - the opponents' reason was very simple, biplanes can also do the work of bombing ground targets, it's just that they carry less fuel. However, large bombers require more professional airfields and more maintenance personnel, which will inevitably bring a lot of pressure to logistics.

In addition, although it scores higher in bombing, it needs fighter escort when dispatched, which reduces the utilization rate of the air force as a whole - flying beasts have limited means to deal with flexible and maneuverable fighters, but it is not the same thing with clumsy bombers. As long as there is a collision that ignores life, it can bring extremely serious damage to the aircraft.

What's more, there are special demons similar to martial artists among the enemies, which further aggravates the uncertainty of the risk.

After all, the cost of losing a bomber is much greater than that of a biplane.

And with the resources of the remaining human beings, it is a question mark how many large bombers can be built.

In the end, Roland insisted on keeping this project.

In the case of low technical level, it does have various shortcomings, and cannot achieve stealth and comprehensive attack and defense, but he has his own considerations.

That is, Neverwinter City needs a machine that can travel long distances to launch an attack on the Bottomless Land when necessary.

No one knows how far the dream world is from eroding the domain of the gods, and the gods may not remain silent all the time. According to Lan's statement, he needs to enter the divine realm from both worlds at the moment when it happens. If the dream suddenly opens the passage of erosion, but he has no way to quickly reach the Bottomless Land, then all previous efforts will be in vain.

Of course, it can only be regarded as a helpless choice to rashly go to the enemy-occupied area while facing the attacks of demons, but it is better to have a choice than no choice, and the bomber is the most feasible solution under the current technical conditions.

Another point is the Sun's Radiance plan.

With the load of Tianhuo, even if it is improved, it is absolutely impossible to shoulder this important task. Without throwing means, even if a feasible explosive device is developed, its effect is limited. It is true that Seagull can cooperate with Hummingbird's weight reduction to carry out high-altitude delivery, but in this way, the detonating bomb can no longer be equipped with God's Stone of Retribution. In the long process of falling, it will be easily destroyed by high-level demons.

For example, if it is discovered by Hezakod, the Lord of the Celestial Vault, it will be a big trouble once it is transferred to other places with a portal.

Therefore, the safest way is to directly turn it into a forbidden body and rely on the Sky Knight to deliver it.

And this cannot be separated from an aircraft with a larger bomb load.

The preliminary plan given by the project team is a four-engine monoplane bomber - the engine of this model needs to be specially developed, and four are to increase redundancy, even if one or two fail, it can also return safely. Judging from the renderings alone, the bomber is like a huge beast, with a wingspan of more than 30 meters, and the tail is forked into twin tails. The stable aerodynamic layout reduces maneuverability, but in exchange for a longer range and easier handling.

When taking off with full fuel, it can carry about four tons of ammunition and fly more than 2,000 kilometers. If you don't consider returning, this number can be doubled, which is enough to meet Roland's requirements to cross the spine of the continent. However, its complexity far exceeds that of Tianhuo, and even if the project team provides special guidance, it is unlikely to be put into production on the assembly line.

In other words, its output will definitely not be too high.

But at least it gives mankind the capital to light up the Sun's Radiance.
