HMS King Alfred

HMS King Alfred is a Royal Naval Reserve training facility located within the Semaphore Tower at HMNB Portsmouth. The site provides military education and training spaces for multiple units, with capacity to accommodate over 200 reservists.

The facility was established in 1994 and replaced two older naval units previously operating at this location. This change marked a shift in how the Royal Naval Reserve was organized in the area.

The Royal Naval Reserve unit here connects with regional educational institutions that matter to its members. These links shape how reservists engage with their local communities beyond their military duties.

The facility is located within Portsmouth Naval Base and functions as an active military training site. Access may be restricted as it remains an operational naval base facility used for regular reserve training activities.

The Semaphore Tower building that houses the facility was originally designed for visual signal communication between ships. This historic architectural element gives the modern training site a distinctive character that blends past and present operations.
