HMS Tireless
HMS Tireless is over 25 years old but still playing a vital role in the front-line Fleet. HMS Tireless is the third of the seven Trafalgar-class submarines built at Barrow by Vickers. She was launched on 17 March 1984, so she has been plying her trade in the Royal Navy for more than a quarter of a century, but a lengthy overhaul of her propulsion, weapons systems and sensors put her in good shape for the gruelling programme of training and trials which followed.
In 2011, she spent ten months on deployment to the Middle East; the trip to support British interests in the region demonstrates how far the T-boats have evolved from their original primary role as Cold War attack submarines.

Military experience
Hywel Griffiths was born in Bradford into a nomadic military family and grew up living in the USA, England, Germany and Belgium, but never far from the family home in West Wales.
Educated initially by Monks at Belmont Abbey in Hereford and then at Sixth Form College in Winchester, he joined the Royal Navy in 1992 and completed initial training appointments in HMS Brilliant, Walney and Avenger.
Volunteering for Service in submarines in 1994, he has conducted operational appointments in HMS Resolution, Peacock & Talent, and was Operations Officer in HMS Tireless prior to the Submarine Command Course (Perisher) in 2004. After Perisher, he spent 30 months as an Executive Officer, initially in HMS Vengeance (Port) immediately followed by HMS Talent.
Hywel joined Flag Officer Sea Training as Head of Training in the Devonport Submarine Training Facility in 2007, delivering both sea and shore training.
In 2009 he joined the Directorate of Navy Resources and Plans in the Ministry of Defence and for two years, which included the Strategic Defence and Security Review, was responsible for articulating the size, shape and cost of the Royal Navy’s underwater force structure. Selected for promotion in April 2011, he undertook a study in Fleet Headquarters prior to taking Command of HMS Tireless in January 2012.
Hywel enjoys cycling, surfing, occasional sailing and time and travel permitting, skiing and scuba diving. He is an avid if sometimes disappointed follower of Welsh Rugby.
