The world's top stealth cruise missile

The world's top stealth cruise missile, AGM- 129 stealth cruise missile.

AGM- 129 stealth cruise missile is a stealth cruise missile developed by the United States using Inertial Guidance System/Terrain Matching System (TERCOM). 1982, the 16 B-52 bomber of the first air squadron of the United States completed the modification of the AGM-86B air-launched cruise missile. With the breakthrough of stealth technology, it began to develop stealth cruise missiles with stronger penetration ability.

The main features of AGM- 129 missile are: first, the unique stealth aerodynamic shape design and ingenious structural layout make the missile have better stealth radar, stealth infrared and stealth acoustic performance; Second, the missile body and wing surface are made of composite materials and absorbing coatings, which greatly reduces the reflection of the missile on radar electromagnetic waves and is not easy to be detected by enemy radar;

Thirdly, using low fuel consumption turbofan engine and air-cooled high-pressure turbine blades can improve thrust, increase range and obviously reduce infrared signal characteristics;

Fourthly, lidar is used in inertial navigation+terrain matching composite guidance system, which improves the accuracy and terrain resolution of its altimeter, enables the missile to track terrain and maneuver at ultra-low altitude and high subsonic speed, and the hit accuracy of the missile is about 16 meters; Fifth, due to the adoption of more new technologies, production has been reduced, and the cost of missiles has greatly increased.

The purchase unit price of AGM-86B is 1.574 million USD, while the purchase unit price of AGM- 129 stealth cruise missile is as high as 6.734 million USD. AGM- 129 is a stealth air-launched strategic missile, which greatly improves the range, hit rate and survivability of AGM-86. The missile can effectively avoid radar and ground air defense systems under any terrain conditions and destroy the enemy's solid ground fortifications.

It was originally planned to produce 2,500 pieces, but it was reduced to 1, 460 pieces and 1, 000 pieces. Finally, due to the end of the cold war, the US Air Force announced the suspension of production in 1992. By the end of 1993, the last AGM 65,438+0,29 had been delivered and 460 pieces were produced.

The AGM- 129A missile is 6.35m long, with a wingspan of 3. 1m, a diameter of 705mm and a total weight of1.68t. The power system is a Williams F112-WR100 turbofan engine. ..

The design concept of "stealth to the end" is adhered to from the shape and structural design to the materials and engines, such as unique stealth aerodynamic shape design, ingenious wing-body fusion structure layout, large swept polyhedron nose cone design, electromagnetic wave absorbing composite materials and absorbing coatings.

The AGM- 129A missile is equipped with the same W-80- 1 thermonuclear warhead as the AGM-86B, and its explosive power varies from 5,000 tons to150,000 tons of TNT equivalent. Its guidance system is the middle inertial navigation system and the last terrain matching guidance system, and the hit accuracy is between 30-90 meters. AGM- 129A is also equipped with a GPS receiver during the upgrade process to further improve the hit accuracy.

AGM- 129A has stealth function and can avoid radar detection during flight. It is the nuclear cruise missile with the best performance and the strongest penetration ability in the US arsenal. The US Air Force originally planned to install AGM- 129A on the B- 1B bomber, but it was not completed.

It is only deployed on the B-52H bomber. An improved B-52H can carry as many as 20 AGM- 129A missiles, of which 8 missiles are installed on the rotating launcher in the internal bomb bay, and the other 12 missiles are hung under the two wings respectively.
