Question to the Ministry of Defence:

To ask the Secretary of State for Defence, what are the requirements of the Royal Navy's a) Stratus LO (Low Observable) and b) Stratus RS (Rapid Strike) programmes.

The Royal Navy has a requirement called the Future Offensive Surface Weapon (FOSuW) which will provide a long range anti-ship strike weapon with land attack capabilities, compatible with the Mk41 Vertical Launch System (VLS). The FOSuW requirement will be met through the Future Cruise Anti-Ship Weapon (FCASW) programme, which comprises two concept solutions, STRATUS LO and STRATUS RS. The STRATUS LO concept is planned to be integrated onto the Type 26 frigate to meet the Royal Navy FoSUW requirement.
