为什么美国国防工业的产品经常很贵?里面是ChatGPT的回答:

The high cost of U.S. defense industry products stems from a combination of factors related to their development, production, and regulatory environment. Here’s an overview of the main reasons:

 

1. Research and Development (R&D) Costs

        Cutting-edge technology: U.S. defense products often incorporate the latest advancements in fields like stealth, artificial intelligence, advanced sensors, and precision weaponry, which require extensive R&D.

        Long development timelines: Programs can take years or decades to design, test, and bring to operational status, with costs accumulating over time.

        High failure tolerance: Many technologies are experimental and may fail multiple times before succeeding, leading to sunk costs.

 

2. Small Production Runs

        Unlike consumer goods, defense systems are often produced in limited quantities due to the specialized nature of their missions. This reduces economies of scale, making each unit more expensive.

 

3. Stringent Testing and Certification

        Products must undergo rigorous testing to ensure reliability, safety, and performance in extreme environments. Meeting military standards often requires additional time, specialized materials, and processes.

 

4. Complex Supply Chains

        Defense products rely on highly specialized components, some of which are sourced from sole suppliers or require rare materials. Managing these complex supply chains adds to costs.

 

5. Labor and Expertise

        Highly skilled labor: Engineers, scientists, and technicians working on defense systems are among the most highly trained and compensated professionals.

        Specialized facilities: Manufacturing often requires unique facilities and tools that add to overhead costs.

 

6. Regulatory and Bureaucratic Requirements

        Compliance: Defense contractors must meet strict U.S. government regulations, including cybersecurity, export controls, and auditing standards, which increase administrative overhead.

        Oversight: Programs are subject to scrutiny from multiple agencies, leading to delays and additional costs.

 

7. Customization and Unique Requirements

        Defense systems are often custom-designed for specific missions or environments, requiring tailored solutions that increase costs compared to off-the-shelf products.

 

8. Geopolitical Considerations

        Strategic investment: The U.S. government sometimes funds expensive programs to maintain technological superiority over adversaries, even if costs are high.

        Export restrictions: Laws like the International Traffic in Arms Regulations (ITAR) limit sales to foreign nations, reducing potential revenue and increasing unit costs.

 

9. Cost-Plus Contracts

        Many defense contracts are structured as “cost-plus,” where contractors are reimbursed for expenses and receive an additional profit margin. This can lead to less incentive to control costs.

 

10. Maintenance and Lifecycle Costs

        U.S. defense products are designed for long service lives, often requiring significant investments in maintenance, upgrades, and sustainment over decades.

 

11. Political and Economic Factors

        Congressional influence: Legislators often advocate for projects that benefit their districts, leading to inefficiencies or inflated costs.

        Industrial base protection: The government supports the defense industry as a strategic sector, sometimes funding projects to maintain jobs or capabilities even if costs are high.

 

In summary, the U.S. defense industry’s focus on innovation, reliability, and national security comes at a premium. While expensive, these systems are designed to provide unparalleled performance and ensure strategic advantages in defense scenarios.

其中有可能存在垄断、暴利、滥用和腐败现象,在加上美国制造文化中的高利润现象。希望以后机器人能够解决这个问题。 -pichawxc- 给 pichawxc 发送悄悄话 pichawxc 的博客首页 (0 bytes) () 01/01/2025 postreply 15:17:42
