The US Defense Security Cooperation Agency (DSCA) has notified Congress of a possible foreign military sale to the UK of Mk-15 Phalanx close-in weapon system (CIWS) Block IB Baseline 2 upgrade kits and SEAL Delivery Vehicles (SDV) Mk-11 shallow water combat submersibles (SWCS).
With a total estimated cost of $165m, the proposed sale was requested by the UK Government and has been approved by the US State Department.
Under the deal, the UK wants to purchase 50 Mk-15 Phalanx CIWS Block IB Baseline 2 upgrade kits and three units of SDV Mk-11 combat submersibles.
The sale includes delivery of associated support and test equipment, and initial spare parts for upgrade kits. It will also cover handling equipment, operator manuals and technical documentation for the SWCSs.
In addition, the possible deal will cover the provision of US Government contractor, engineering, training technical and logistical services, as well as other related elements of logistics and programme support.
After the acquisition of the SDV Mk-11 SWCSs, the UK will be able to continue its maritime partnership, interoperability and regional security capabilities.
In order to implement the proposed sale, the US Government and contractor representatives would require participation in programme and technical reviews, as well as related training and maintenance support.
The Phalanx Baseline 2 radar upgrade kits will be used by the British Royal Navy for close-in ship self-defence against air and surface threats on the country’s naval combatants and auxiliaries.
Teledyne Brown Engineering and Raytheon Missile Systems will serve as the principal contractors for the potential sale of the SDV Mk-11 submersibles and radar upgrade kits.
