The U.S. Department of the Interior has issued a request for information (RFI) seeking concepts for performing orbital launches from offshore sites. The move is part of a broader effort to alleviate growing congestion at existing spaceports, which have faced increasing demand from both government and commercial launches.
The RFI, issued by the Bureau of Ocean Energy Management (BOEM) within the Interior Department, aims to gather data on technical, environmental, and regulatory aspects of offshore launch operations. This includes potential launch platforms, sea-based ranges, and integration with existing maritime infrastructure. The initiative could complement ongoing work by the Federal Aviation Administration (FAA) and the Department of Transportation to expand U.S. launch capacity.
No specific timeline or budget has been outlined for the offshore launch program, but the RFI marks an early step in exploring alternatives to land-based spaceports. The Interior Department is seeking responses by March 2024. The effort follows years of study by the FAA on sea launch concepts, which have previously been pursued by companies like Sea Launch and SpaceX with its floating platform concepts.
The significance lies in reducing bottlenecks at key spaceports such as Cape Canaveral and Vandenberg, which have seen launch cadences rise sharply due to the growth of commercial spaceflight and national security missions. Offshore launches could also offer safety advantages by avoiding overflight of populated areas.
A key counter-argument is that offshore launches face significant technical, environmental, and logistical hurdles, including weather risks, maritime traffic, and the added costs of sea-based operations. Critics also note that land-based spaceports have room for expansion through pad upgrades and range modernization, potentially making offshore options unnecessary in the near term.
