Li Yunxiang stayed in Colombo for three months, and he didn't even go back to attend the combat meeting, which had something to do with this kind of bomber that was about to join the combat sequence.

At present, 60 "Condor" aircraft have been delivered to the army aviation.

In addition to the 20 in Sri Lanka, 20 aircraft are being tested in the Extreme Plateau, while another 20 are in the far north of the empire, ready to begin testing their performance in freezing conditions in October. In Sri Lanka, performance tests are being conducted in high temperature and humidity environments.

If anything, the effect of high temperatures on bomber performance is similar to that of a plateau.

The higher the temperature, the lower the air pressure, the lower the power output of the engine at sea level, and the take-off weight of the bomber will be significantly reduced.

In addition, the high humidity environment can have an impact on the main equipment, as well as the service life of the bomber.

Even if you don't have to consider the life of the airframe, you should also consider the reliability of the engine, radio and other equipment.

Of course, the maximum range of the bomber in various states was determined by test flights, as well as trouble-free working time in extreme conditions.

All this will affect the combat capability of the bomber.

Three months is enough time to complete most of the testing work.

According to Li Yunxiang's introduction, the "Condor" has not yet reached a perfect state.

In the hot and humid tropics, the engine output during the take-off phase is reduced by at least 15%, so the actual maximum usable take-off weight is only 56 tons, which is 8 tons lower than the designed 64 tons, and the take-off taxiing distance is up to 2,100 meters, which is more than the runway length of almost all field airfields.

Crucially, you have to use hard runways.

If the bomb load of 6 tons is guaranteed, the maximum combat radius that can be achieved is only 2,500 kilometers in the case of a half-distance downwind flight.

In order to reach a combat radius of 3,000 kilometers, the bomb load can only be reduced to 3 tons, that is, 3 tons more aviation gasoline.

According to tests, without self-defense weapons and with a reduction in the number of weapon operators, it is possible to carry bombs up to 4 tons at a combat radius of 3000 km.

If anything, the biggest problem is actually the ceiling.

Even if the bomb is loaded with 3 tons and the remaining 40% of the fuel, that is, only the return fuel, the usable ceiling of the "Condor" is only 7,000 meters.

This height can be said to be high or low.

At the time of design, the army aviation regarded the 10,000-meter ceiling as the most ideal means of defense, and also invested heavily in the development of high-altitude bombing sighting equipment.

According to the pre-war point of view, because the effective fire altitude of most anti-aircraft guns was less than 10,000 meters, as long as the bomber flew at an altitude of more than 10,000 meters, it could avoid anti-aircraft fire on the ground.

In addition, even if there are a few large-caliber anti-aircraft guns that can hit more than 10,000 meters, they will not be accurate.

In addition, many fighter jets designed and produced before the outbreak of the Great War had a practical combat ceiling of less than 10,000 meters.

That is, even a fighter can't fly that high.

If you fly higher than a fighter, then what else is there to be afraid of?

Flying high enough not only reduces combat losses, but also allows bombers to drop bombs without interference, thereby increasing the efficiency of bombing.

At least until the outbreak of the Great War, no one felt that the hit rate of high-altitude bombs was a big problem.

The altitude of 7,000 meters can be said to be very embarrassing, not only within the interception range of fighters, but also within the effective shooting height of all large-caliber anti-aircraft guns.

In fact, this is also the inevitable result of the use of simple engines.

Fortunately, the problem of insufficient ceilings is still within the tolerable range.

The key point is that through the test of war, or the test of actual combat, many theories summed up before the war have been proved to be wrong.

High-altitude bombing is one of them.

As early as when the strategic bombing of the Imperial Kingdom was carried out, the Imperial Army Aviation found that under the premise of adopting correct bombing tactics, the loss rate of low-altitude entry and high-altitude entry was not much different, and the hit rate of low-altitude bombs was significantly higher, which meant that fewer bombers and fewer bombs could be used to complete the bombing mission, so as to control the overall combat loss rate within a lower range.

In addition, heavy bombers can use ferocious self-defense firepower against enemy fighters.

Provided, of course, that there is no significant generational gap.

For example, during the offensive and defensive battles on the island, the heavy bombers of the Imperial Army Aviation suffered a big loss in front of the F4F and P-41, and the losses were very heavy.

If anything, the key is one point.

Fleet size.

As long as the number of bombers is large enough, the combat loss rate can be effectively reduced, and the combat efficiency of a single sortie can also be improved by intensive bombing.

Of course, Li Yunxiang brought Bai Zhizhan over to let Bai Zhizhan know that the kind of bomber he had instigated He Pengfei to invest in and develop at his own expense was about to reach service and would soon carry out its first combat mission. If there is no accident, it is to carry leaflets to the Van Roe area to engage in psychological warfare.

This kind of low-intensity operation can also be regarded as a combat test before service.

Because the route was cut off, the Bran army deployed in the Van Luo area had long been an empty shelf, not to mention the advanced fighters, not even anti-aircraft guns.

Of course, the occupation forces of the colonies did not need many advanced weapons.

Even now, in many colonial strongholds in the Van Roe region, a Vickers or Maxim heavy machine gun can make a disobedient princely state become honest and obedient. If it doesn't work anymore, deploying a few small-caliber mountain guns and sending a few biplane reconnaissance planes to fly a few times will be enough to keep the peace of the side.

Previously, reconnaissance aircraft sent to the Van Rowe area were rarely intercepted by fighters.

Judging from the current situation, the kingdom of Bran may be mentally ready to abandon the Van Luo region.

If they can't defend the Kibu Fortress and the Syvan Canal, and if they can't regain the sea control of Muahai, the Van Luo region will have no value to the Bran Kingdom.

What's the use of holding on without access to the resources produced by this colony?

It is not cheap to maintain a sufficiently strong garrison in the Van Roe area.

In Li Yunxiang's words, it is actually to test in actual combat, feedback the problems found to the manufacturer, and then modify them in the next batch.

However, Li Yunxiang also clearly told Bai Zhizhan.

In the fourth quarter, next month, 140 of the first 500 will be delivered, while another 300 will be delivered in November and December.

Obviously, this is also what interests the White Stop War the most.

Although the bombing of Austria has not yet been discussed, according to Li Yunxiang's meaning, by the end of the year, even if the above proposes to bomb Austria, it will be possible to dispatch enough bombers to carry out the mission without affecting other directions, so as to ensure that the overall strategy will not change too much.

If you want to say anything, just bomb a few airfields in the northwest of Austria, and a few hundred "Condor" are enough.

The key is that if they do not bomb the northwest of Austria, then all these "Condors" can use Male Island to bomb Socotra Island, or take off from the airfield near Gwadar to bomb the Kibu Fortress, so as to greatly reduce the combat pressure of the navy.

Obviously, this is also the issue that was raised at the joint meeting.

Of course, with hundreds of bombers in hand, it is actually easy to say how to use them.

Li Yunxiang introduced this super bomber to Bai Zhizhan, and mentioned the matter of mass production, in fact, he wanted Bai Zhizhan to rest assured, and in the end, he would have the back.
