Nuclear Submarines & Clancy's The Hunt for Red October

From yesterday's Telegraph editorial by PM David Cameron, "We need a nuclear deterrent more than ever:"

This week marks the completion of the 100th patrol by the Royal Navy’s Vanguard-class submarines, which carry our Trident nuclear missiles.

Here is the runaway bestseller that launched Tom Clancy's phenomenal career.

The Hunt for Red October remains a masterpiece of military fiction by one of the world's most popular authors, a man whose shockingly realistic scenarios continue to hold us in thrall.Somewhere under the Atlantic, a Soviet sub commander has just made a fateful decision. The Red October is heading west. The Americans want her. The Russians want her back. And the most incredible chase in history is on...
