Contemporary strategic bombers are actually large aerodynamic objects at the bottom of the atmosphere, and there is not much essential difference between flight altitude and flight speed from ordinary passenger aircraft. Even its maximum speed is only around Mach 2, which is much lower than the Concorde airliner with a full cruise speed of Mach 2.4. Therefore, while Union Jack was still in service, many people hoped to directly convert the Union Jack into a certain strategic bomber. Mach 2's maximum flight speed can be achieved and surpassed by many large fighters with relatively strong performance and long-range interception performance when driving after-force. This risk that traditional strategic bombers will be intercepted or even shot down by the opponent's fighter in mid-air. So there are strategic bombers with full stealth like B2. However, with the advancement of anti-stealth technology, B2 cannot ensure the risk of being completely intercepted by fighters with active phased arrays with huge anti-stealth system. Therefore, the combat effectiveness of traditional strategic bombers in the future will actually gradually decline. The bigger problem is that as long as the traditional strategic bomber flies to the supersonic state, its time of stagnation will plummet. The decline in effective space stagnation time means a significant reduction in the bombing radius. For example, the Tu160 strategic bomber with the largest take-off weight in the world and can reach 260 tons. If it is lightly loaded with 15 tons of bombs and the entire range is subsonic, it can fly directly 16,000 kilometers; if it is carrying a cruise missile with a range of 2,500 kilometers, it will have the ability to take off from the base at the high latitude of Eurasian , directly attack important targets of the superpower, and then return safely. That is, the actual round-trip combat radius can be as high as more than 8,000 kilometers. However, if the entire supersonic penetration is carried out, the bombing radius will drop straight to within 2,500 kilometers. Needless to say, it is a bit difficult to bomb North American targets from the territory, it is not necessary to say, to bomb Gibraltar from the transatlantic Ocean or Arctic Ocean . These factors have also led to the fact that in addition to the bomber groups of superpowers, the strategic bombers of other major powers are increasingly deployed in actual combat, and they have even become directly a role in making soybeans. But even the three active strategic bombers of superpowers have been declining in recent years. If B1B and B2 are really useful, then the superpower Air Force will not have to develop and mass-equipped new models such as B21. But in essence, even B21 still does not solve the contradiction between high-speed flight, maximum air time and actual combat radius; even compared with B2, its actual combat radius and ammunition load capacity do not increase but decrease. At present, to completely resolve this kind of contradiction, only secondary orbit bombers can be developed, or suborbital bombers. Most people focus on the greater strategic advantage of sub-orbit bombers that can bomb any target on the Earth's surface within 1 hour, but they often ignore the greater strategic advantage of the sub-orbit that can be left empty for a long time to wait for the bombing opportunity. After all, the sword of Damocles, which has been hanging over the opponent for a long time, is even more strategic than the sword's final fall. In the past, the only ones that had not flown in orbited satellite . However, once it enters orbit and flies, its ballistics will be very rigid and can easily be intercepted by the anti-missile system . Moreover, every time the orbital flying objects circle the earth, their orbits projected on the ground are completely different. Go to target fixed targets on the same ground or on the sea again. It takes at least 24 hours later. This is also the fundamental reason why major countries are unwilling to send all nuclear warheads and into space to deploy. The secondary orbit bomber bounces over the atmosphere, and its orbit is unpredictable and difficult to intercept; in addition, the secondary orbit bomber can also drift horizontally on a large scale, so that it theoretically has the ability to continue aiming and hit the same target below the flight trajectory after one or even a few laps around the earth. It also has the ability to strike moving targets on land or ocean surfaces. The first generation of secondary orbit bombers should be in two-stage horizontal skiing takeoff mode.
takes off horizontally from a first-stage carrier of 500 ton or even 700 ton, and takes off at a height of 15,000 meters. The two are separated. The rocket engine of the secondary orbit bomber is turned on and climbs to a height of 200 kilometers, and then dives down and enters the atmosphere to perform water-wave ballistic flight. The lowest trajectory is about 60 kilometers; and then accelerates the climb by relying on powerful bow elastic waves, with an average flight speed of Mach 15. You can carry 20-ton special bombs, standby at high altitude for 7 to 30 days, ready to drop bombs at any time! How many people in the world are not afraid of this?
