In the early 20th Century - the art of modern sea-faring warfare was to change forever with the introduction of the purpose built attack submarine.
The power, stealth and muscle these iron beasts could not be denied. Their impact in times of war and of peace - is absolutely indelible in modern history.
Beneath the waves - the work and lives of the submariner has never been an easy one. Their dedication, resilience and courage in service of their country is legendary.
It is this, remarkable match of man and machine - a harmony of courage that Ballast celebrates.
"Of all the branches of men in the forces there is none which shows more devotion and faces grimmer perils than the submariners"
-Sir Winston Churchill
