흥미있는 내용이 많습니다만, DDG-1000의 원래 개발 목표는 아이오와급 퇴역 후에 상실된 미해군의 대구경 함포 화력지원능력을 좀 더 현대적인 기술로 대체하기 위함이었다고 하네요. 

"DDG-1000s were originally intended to replace, in a technologically more modern form, the large-caliber naval gun fire capability that the Navy lost when it retired its Iowa-class battleships in the early 1990s, 25 to improve the Navy’s general capabilities for operating in defended littoral waters, and to introduce several new technologies that would be available for use on future Navy ships. The DDG-1000 was also intended to serve as the basis for a planned cruiser called CG(X) that was subsequently canceled.2"

원래는 DDG-51을 2000년대 중반에 조달 종료하고 DDG-1000을 32척 조달하기를 원했지만 최종적으론 3척으로 종료되고, DDG-51이 미해군 역사상 가장 장기 조달 프로젝트가 돼 버렸습니다. 

"Navy plans for many years called for ending DDG-51 procurement in FY2005, to be followed by procurement of up to 32 DDG-1000s and some number of CG(X)s. In subsequent years, the planned total number of DDG-1000s was reduced to 16 to 24, then to 7, and finally to 3."

Report to Congress on U.S. Navy Destroyer Programs

March 29, 2023 8:35 AM

The following is the March 27, 2023, Congressional Research Service report, Navy DDG-51 and DDG-1000 Destroyer Programs: Background and Issues for Congress.

From the report

The Arleigh Burke (DDG-51) class destroyer program is one of the longest-running shipbuilding programs in Navy history. The Navy began procuring DDG-51s, also known as Aegis destroyers, in FY1985, and a total of 92 have been procured through FY2023, including three in FY2023. From FY1989 through FY2005, DDG-51s were procured in annual quantities of two to five ships per year. Since FY2010, they have been procured in annual quantities of one to three ships per year. (The Navy did not procure any DDG-51s in FY2006-FY2009. Instead, the Navy in FY2007-FY2009 procured three Zumwalt [DDG-1000] class destroyers. The Navy plans no further procurement of DDG-1000s.)

The Navy’s proposed FY2024 budget requests the procurement of two more DDG-51s in FY2024. The Navy’s FY2024 five-year (FY2024-FY2028) shipbuilding plan includes 10 DDG-51s, to be procured at a rate of two ships per year.

As part of its FY2023 budget submission, the Navy requested authority for using a multiyear procurement (MYP) contract for DDG-51s scheduled for procurement in FY2023-FY2027. Congress, as part of its action on the Navy’s proposed FY2023 budget, approved this request. Four previous MYP contracts for the DDG-51 program covered DDG-51s procured in FY1998-FY2001, FY2002-FY2005, FY2013-FY2017, and FY2018-FY2022.

The first DDG-51 entered service in 1991, and a total of 72 have been delivered as of March 2023. The DDG-51 design has been updated multiple times over the years; the version currently being procured, called the Flight III DDG-51 design, incorporates a new and more capable radar called the SPY-6 radar.

DDG-51s currently cost about $2.2 billion each to procure. The budget estimates the combined procurement cost of the two DDG-51s requested for procurement in FY2024 at $4,432.8 million (i.e., about $4.4 billion). The two ships have received $233.6 million in prior-year Economic Order Quantity (EOQ) funding, which is a kind of advance procurement (AP) funding that can occur under an MYP contract. The Navy’s proposed FY2024 budget requests the remaining $4,199.2 million needed to complete the two ships’ estimated combined procurement cost. The Navy’s proposed FY2024 budget also requests $284.0 million in EOQ funding for DDG-51s to be procured under the FY2023-FY2027 MYP contract, and $225.9 million in cost-to-complete funding to cover cost growth on DDG-51s procured in prior fiscal years.

함포는 아이오와의 16인치 포탄도 함재기가 달고 가서 던지는 2,000 파운드 폭탄과 비교하면 reach와 파괴력 모두 훨씬 떨어지는데 대신 포탄이 폭탄보다는 싸고, 날씨가 나빠도 쏠 수 있다는 것 때문에 원했던 것인지 궁금하네요.

8인치나 11인치도 아니고 155mm로는 위력의 한계를 뛰어넘을 수 없는데 아무리 냉전 끝나고 연안작전에 집중한다 쳐도 뭔 생각이었는지..

진짜 지속적인 함포지원이 필요했으면 155mm나 8인치 싣는 현대판 모니터함을 싸게 뽑는 게 나았을 텐데요.
