UK looks to buy new combat submersibles

21 September 2018

The United Kingdom is planning to acquire new US-built manned combat submersibles to replace the current Mk 8 Mod 1 SEAL Delivery Vehicles (SDVs) used by its Special Boat Service (SBS).

Disclosing the Foreign Military Sales (FMS) case on 20 September, the US Defense Security Cooperation Agency (DSCA) said the UK had asked to buy three SDVs Mk 11 shallow water combat submersibles (SWCS) for an estimated USD90 million. The FMS request, notified to Congress by the DSCA on 19 September, also includes spares, handling equipment, test equipment, operator manuals, and technical documentation.

Developed by Teledyne Brown Engineering for the US Special Forces Command (USSOCOM) as a replacement for the SDV Mk 8 Mod 1 vehicle, the SDV Mk 11 SWCS is a free-flooded combat submersible vehicle specifically designed to insert and extract special forces in high-threat areas.
