Question to the Ministry of Defence:

To ask the Secretary of State for Defence, what steps he is taking to ensure that all naval vessels have upgraded computer operating systems which are compatible with onshore systems.

Current legacy Computer Information Systems will be replaced imminently to ensure optimum compatibility for naval vessels. On current plans, the first installation of the new upgraded system is expected to commence in late 2021.

In addition, there is a funded programme of work to upgrade and maintain legacy systems and to ensure accreditation and interoperability is maintained.
