Using this method, he added, the service can get the most out of the weapons packed on the attack boat.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u201cIf you have 30 torpedoes onboard, you may only have one or two targets within range of your sensors and weapons,\u201d Clark said, arguing that with third-party targeting, one could conceivably use the submarine as a submerged arsenal.<br><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The concept is similar to the cooperative engagement technology that the surface navy is developing, where an aircraft such as an F-35 or E-2D detects an incoming hostile track and relays kill-quality target data to the ship for engagement with a long-range missile, such as an SM-6.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The technology allows ships to remain stealthy by keeping off its big air-warfare radars, and instead relying on airborne sensors for targeting data.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Applying the same concept to the submarine world still has some issues, however, because torpedoes fired at long ranges take a good long while to reach their targets, Clark said. That means the Navy will have to puzzle out how to relay targeting updates to the Mark 48 as it travels toward the enemy ship from so far away.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>The award is part of ONR\u2019s Torpedo Advanced Propulsion System project that has some lofty ambitions attached to it.<\/p>\n","protected":false},"author":7,"featured_media":29154,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"_yoast_wpseo_meta-robots-noindex":"","_yoast_wpseo_meta-robots-nofollow":"","_yoast_wpseo_canonical":"","_acf":"","_yoast_wpseo_primary_category":16,"_jetpack_feature_clip_id":0,"_jetpack_memberships_contains_paid_content":false,"footnotes":"","_smg_distribution_targets":{"7":{"categories":["your-navy","news","middle-column","home","daily-news-roundup","newsletters"],"primary_category":"your-navy"}}},"categories":[160,12,16,36],"tags":[],"coauthors":[3361],"class_list":["post-54921","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-daily-news-roundup","category-industry","category-naval","category-newsletters"],"acf":{"subheadline":"","legacy_arc_id":"FVC5BFPE5FFHFIBBSSXSRUP24E","arc_canonical_url":"\/naval\/2018\/06\/13\/us-navy-pushing-ahead-with-bid-to-extend-the-range-of-its-sub-killer-torpedo\/","remove_feature_photo":false,"is_sponsored":false,"subtype":"","redirect_url":"","disable_inline_ads":false,"native_logo_pretext":"Presented By:"},"yoast_head":"<!-- This site is optimized with the Yoast SEO Premium plugin v26.0 (Yoast SEO v28.1) - https:\/\/yoast.com\/product\/yoast-seo-premium-wordpress\/ -->\n<title>US Navy pushes ahead with bid to extend the range of its sub-killer torpedo - Defense News<\/title>\n<meta name=\"description\" content=\"The award is part of ONR\u2019s Torpedo Advanced Propulsion System project that has some lofty ambitions attached to it.\" \/>\n<meta name=\"robots\" content=\"noindex, follow, max-snippet:-1, max-image-preview:large, max-video-preview:-1\" \/>\n<meta property=\"og:locale\" content=\"en_US\" \/>\n<meta property=\"og:type\" content=\"article\" \/>\n<meta property=\"og:title\" content=\"US Navy pushes ahead with bid to extend the range of its sub-killer torpedo\" \/>\n<meta property=\"og:description\" content=\"The award is part of ONR\u2019s Torpedo Advanced Propulsion System project that has some lofty ambitions attached to it.\" \/>\n<meta property=\"og:url\" content=\"https:\/\/one.sightlinemg.com\/defensenews\/naval\/2018\/06\/13\/us-navy-pushing-ahead-with-bid-to-extend-the-range-of-its-sub-killer-torpedo\/\" \/>\n<meta property=\"og:site_name\" content=\"Defense News\" \/>\n<meta property=\"article:published_time\" content=\"2018-06-13T15:32:16+00:00\" \/>\n<meta property=\"article:modified_time\" content=\"2026-08-08T00:05:48+00:00\" \/>\n<meta name=\"author\" content=\"David B.
