Chapter 074 Christine

The Navy developed the AIM-7 Sparrow medium-range missile in the 1950s.

The AIM-7 has an effective range of about 36 kilometers, uses semi-active radar guidance, and can attack air targets within and beyond line-of-sight.

The AIM-7, along with the infrared-guided AIM-9 Sidewinder, took the place of the radar and infrared-guided AIM-4 missiles in service at the time.

But its disadvantage is that it can only attack one target at the same time, and the fighter plane must continue to point in the direction of the enemy plane after launching it, which brings great trouble and danger to the fighter plane that provides the fire control information.

Shortly after the Vietnam War ended in 1975, the Department of Defense established a research group of air and naval pilots and maintenance logistics personnel with combat experience.

The research team spent more than a year, focusing on the actual combat problems encountered by the two sides in the Vietnam battlefield, mainly the defects exposed by the AIM-7 "Sparrow" missile in actual combat, as well as various possible occurrences in the next 30 years. Air threats are extensively and deeply discussed and studied.

The findings suggest that the threat to fighter jets comes from a variety of targets flying at subsonic to Mach 3 speeds in the range from sea level to tropospheric altitude, and recommends an attack at medium range.

Because most targets are located in the 5-74km area, outside these areas, closer and farther targets can be left to other missiles and cannons to deal with, so the concept of advanced medium-range air-to-air missiles - AMRAAM is accepted. .

In September 1976, the group published the "Multi-Service Joint Operational Requirements" for advanced air-to-air missiles.

This Joint Operational Requirements clearly articulates the actual needs of the operational component.

The military's operational requirements for advanced air-to-air missiles can be summarized as:

1. When a missile engages with a target, it can destroy the target under any weather conditions and any electronic interference environment during the life cycle of the missile system, that is, it has a high probability of killing.

2, the use of missiles should be simple and convenient, and can adapt to a variety of fighters.

3. After the missile leaves the carrier aircraft, it can search for the target independently, without the need for long-term irradiation of the carrier aircraft, that is, it has the ability to "don't care after launch".

4. The missile and its auxiliary systems must be reliable and easy to maintain, and the inventory should remain intact for many years, and can withstand the test of harsh mounting environments, including salt erosion at sea and the environment of engine combustion products. Perfect performance.

5. The missile should be small in size and light in weight, which can increase the bomb-carrying capacity of the carrier aircraft for one combat flight.

6. The missile is fast and can hit the target quickly.

7. The cost of the missile system should be quite low.

From 1976 to 1978, five groups/companies including Ford Aerospace/Marconi Defense, General Dynamics, Hughes, Northrop/Motorola, and Raytheon/McDonnell Douglas participated in the bidding. Comparative studies on lethality, performance, firepower, reliability/maintainability, etc. were conducted extensively.

In the end, Hughes and Raytheon won.

From 1979 to 1981, Hughes and Raytheon were awarded 33-month contracts to develop AMRAAM.

At this stage, the flight prototypes of the two companies will be tested and certified against the "multi-service joint operation requirements".

From 1981 to 1989, Hughes was awarded a 54-month development contract in December 1981.

In addition to the need to develop new transmitters, the early stage of this phase is basically a period of refinement and refinement of engineering design, and 99 test missiles are planned to be built.

In January 1985, the Air Force, Navy, and Hughes Corporation embarked on a reprogramming plan to extend the full-scale development phase to 79 months, but it took 85 months, and the number of test missiles increased to 122, and eventually 128 were made.

From December 1984 to January 1989, 94 guided test bombs and 6 separate control test bombs were used.

A total of 79 development tests and qualifications and 21 initial operational tests and qualifications were carried out.

Of the 75 recorded missile launches, 58 were successful, of which 19 directly hit the target, with a launch success rate of 77%.

From February 1990 to May 1993, the Air Force Combat Test and Qualification Center conducted the first phase of follow-up operational tests and qualifications.

From January to July 1991, the Navy fired six production batch 2 AIM-120A missiles from F/A-18C/D aircraft.

From June 1993 to March 1996, the Air Warfare Center conducted the second phase of follow-up operational trials and qualifications to further test the operational capabilities of the AMRAAM.

These tests are used to characterize the operational effectiveness and suitability of the missile in a real tactical environment.

After reaching the final state, if the piston is slowly reversed to complete the quasi-static isothermal compression process, the process will proceed step by step along the state experienced by the original process.

It's just the opposite direction, and at each step the outside world does work on the system and the system releases heat to the constant temperature heat source.

It is exactly equal to the work done by the system in the positive process and the heat absorbed from the heat source, and all the influences of the original process in the outside world are eliminated.

Thus, the quasi-static process without friction and other losses is a reversible process.

However, the shooting down scene that everyone imagined did not happen.

Through his metal dragon's third talent, Metal Transformation, Tal transformed himself into a spherical umbrella-shaped Tal, and took the 22kg high-explosive impact of ten consecutive AIM-120B air-to-air missiles. www.wuxiamtl.com~ The missile hit, but the enemy was all right. This reality immediately drove the pilot crazy and began to pursue Tan.

Knowing that he couldn't catch up with the iron birds, he carried the machine guns and killed the two bases. At this time, the surface-to-air missile Patriots in the bases finally came online.

......

"Fuck, I think my reaction should be panic."

Christine was taken aback and said, "I mean your company, which has recently been associated with a tragic incident."

Tony didn't listen, and continued to play stupid, trying to change the subject and let Christine go.

"Yeah, they sent me an invitation. I don't know what I can say."

In response, Christine, who saw Tony's thoughts, naturally said with a sneer, "I really almost believed it."

Seeing that he couldn't continue, Tony had to take his absence, "I haven't heard of it since I went out for a few months?"

Christine pouted, she was speechless to Tony. She said, "Is this what you call being responsible?"

"It's called Comilla, have you heard of it?"

Saying that, Christine took the photo from her arms and handed it to Tony.

Tony, who took the photo, was stunned when he saw the tragic situation above, and then saw the Stark Arms logo on the back photo, Tony suppressed his anger and said.

"When was this taken?"

Christine: "Yesterday!"

yesterday?

Tony heaved a sigh of relief and shook his head. "I didn't allow transportation."

Christine: "Your company allows it."

Tony suddenly understood something and gritted his teeth, "I'm not my company."
