{ "item_title" : "Sub Hunters", "item_author" : [" Tim Ripley "], "item_description" : "Sub Hunters tells the story of anti-submarine warfare from the early part of the 20th century through to the modern day. It looks at the early efforts at countering submarines in World Wars One and Two as the German U-boat threat escalated, and the allies countered with new sonar technology to detect submarines under water and launched fleets of maritime patrol aircraft. In the Cold War era, the development of nuclear-powered submarines completely changed how navies and air forces hunted underwater prey. SOSUS underwater listening systems, helicopters with dipping sonar, guided torpedoes and long-range maritime patrol aircraft all played their part. The latest Russian and Chinese submarine threats are prompting the development of new technology to defeat the latest generations of submarines.", "item_img_path" : "https://covers2.booksamillion.com/covers/bam/1/80/282/954/1802829547_b.jpg", "price_data" : { "retail_price" : "17.99", "online_price" : "17.99", "our_price" : "17.99", "club_price" : "17.99", "savings_pct" : "0", "savings_amt" : "0.00", "club_savings_pct" : "0", "club_savings_amt" : "0.00", "discount_pct" : "10", "store_price" : "" } }
