[Global Times correspondent Shi Liufeng] on the 18th, the website of the US Naval Research Society disclosed the report submitted to the US Congress last week, revealing the construction cost and plan of the “Ford” class aircraft carrier. It shows that the technical failure of the “Ford” aircraft carrier has not been completely eliminated, and the US Navy has to continue to increase the budget, which has also aroused doubts from the US Congress. < / P > < p > according to the report, the U.S. Navy has added about $2.715 billion to the first four “Ford” class aircraft carriers in its budget for fiscal year 2021. Among them, the first ship “Ford” needs an additional budget of $71 million, the carrier of ship 3 “enterprise” (cvn-80) needs an additional budget of $997.5 million, and the ship No.4 “Miller” needs an additional budget of $1646.5 million. < p > < p > < p > < p > “Ford” aircraft carrier was ordered in fiscal year 2008, which was originally planned to be delivered for use in 2014. Due to many technical problems, the aircraft carrier was put into service on July 22, 2017. The initial total construction budget of the ship is 10.5 billion US dollars, which has been as high as 133165 million US dollars. The U.S. Navy is currently working to complete the testing and certification of the ship’s 11 weapon elevators, which are expected to be completed by may 2021. In addition, it is necessary to solve the technical problems such as the high failure rate of electromagnetic catapult and the isolation and maintenance of electric drive system. Therefore, the sea trial time for the “impact test” of the ship can not be determined, and the deployment time of the carrier is expected to be extended to 2022. < p > < p > the “Kennedy” (cvn-79) was ordered in fiscal year 2013, and the construction cost is currently estimated to be about 11.4 billion US dollars. The manufacturing process of the ship has learned from the experience and lessons of the “Ford” and adopted a series of improvement measures. Currently, 70% of the construction progress has been completed, and it is planned to be delivered to the US Navy in September 2024. < / P > < p > the “enterprise” ship 3 was ordered in fiscal year 2018. The construction cost is currently estimated to be about $12.3 billion and is scheduled to be delivered in March 2028. The No.4 “Miller” was originally ordered in the 2019 fiscal year, and the construction cost is currently estimated to be about 12.4 billion US dollars, which is scheduled to be delivered in February 2032. The U.S. Navy estimates that the cost of building the enterprise and Miller aircraft carriers can be shared equally, saving about $4 billion. According to the 30-year shipbuilding plan of the U.S. Navy in fiscal year 2020, starting from fiscal year 2028, the United States will build an aircraft carrier every four years, and strive to reproduce the development goal of 12 aircraft carriers after 2060. But the plan faces a series of tests. < / P > < p > numerous technical problems and construction cost overruns seriously, coupled with the rapid development of adversary anti-ship ballistic missiles and advanced anti-ship cruise missiles, the construction of “Ford” class aircraft carrier has been cast a shadow. The U.S. Congress has begun to discuss what kind of aircraft carrier should be ordered in fiscal year 2024 after the “Miller” – a large deck nuclear powered aircraft carrier such as the Ford class, a smaller light aircraft carrier or a conventional power carrier? Light carrier can take off and land F-35B or all UAVs, which is a cost-effective carrier construction option being studied by the US Navy in recent years.
