Naval Air Command Sub Aqua Club

The Naval Air Command Sub Aqua Club (NACSAC) was an organization within the Royal Navy that oversaw sports and technical diving training activities for naval aviation and fleet units. Today, it has branches at RNAS Culdrose (HMS Seahawk) and RNAS Yeovilton (HMS Heron). Both bases provide training, and club members regularly dive into their local areas on weekends. Diving instruction, from beginner to advanced level, is offered under the auspices of the British Sub-Aqua Club. In 2005, NACSAC was closed down as an organization in favour of the Royal Navy Sub Aqua Club, which is what Lieutenant Graham and CPO Larn had wanted from the outset of NACSAC, which was only given that title since HMS Vernon, the RN Diving School at Portsmouth would not support the idea of sport diving within the service.^{[citation needed]}
