US Navy 30 year ship plans include an aircraft carrier every five years

The US Navy has a 30 year shipbuilding plan and there are Department of Defense (DoD) and Navy guidance documents.

In the near-term planning period, available platforms are limited to existing ships, flight upgrades, a new amphibious platform (LX(R)), and the SSBN(X). Advanced weapons and sensors are expected to continue to drive electrical system requirements as are energy security considerations.

The mid-term planning period introduces several new platforms: DDG(X) in FY 2031, LCS(X) in FY2030, a large deck amphibious ship in FY 2024, and potentially an additional variant of DDG 51 in the FY2022-2024 timeframe. Advanced weapons and sensors with higher power demands as well as energy security will continue to be the primary electrical requirement drivers during this period. Capabilities such as arctic operations, platforms with mission modules, and low observability may play key roles.

The far-term involves additional uncertainty, but it is expected that additional directed energy weapons requiring even more power will become available as well as higherpowered sensors and rail guns of increasing size and capability. It is likely that Navy platforms will operate these systems simultaneously. The Navy will also introduce additional modular ships with modular mission payloads and electric power systems will be required to provide improved power system flexibility. Far-term power systems are anticipated to become more autonomous and simple to operate, smaller, lighter and less costly.

Three of the new Ford Aircraft carriers have been announced but the plan has been for ten Ford class carriers One every five years from 2013 would mean carriers out to 2058.
