WATCH THE NEW AND IMPROVED VERSION :    • "COORDINATED ASW PART I"  1970s U.S. NAVY ...   Support Our Channel :   / periscopefilm   "Co-ordinated Anti-Submarine Warfare" (1970s) discusses how surface ships, aircraft and submarines work together to unravel the submarine threat. The film explains both passive and active sonar, and shows how sonobuoys and other technology are deployed to locate enemy submarines. Features footage of a carrier battle group, Soviet submarines, and USN warships as well as Tracker aircraft and rotary wing ASW helicopters. Visible in the film is USS Stein (DE-1065) and USS Badger (FF-1071). The film shows strategies used to counter Soviet submarines. ASW operations rely on a combination of aircraft, surface ships, and submarines. The key to success lies in integrating the strengths of each platform to compensate for their individual limitations, ensuring early detection and swift elimination of the threat. 0:00 – The Soviet submarine force poses a significant threat to U.S. naval and coastal targets with torpedoes and missiles launched from great distances. 0:31 – The U.S. Navy's ability to maintain open sea lanes and protect ships is essential to national security. 0:44 – Anti-submarine warfare (ASW) requires coordinated efforts between aircraft, ships, and submarines. 1:45 – Defense strategy focuses on detecting and attacking enemy submarines before they can strike. 2:36 – Aircraft offer speed and flexibility in ASW, placing sensors and delivering weapons at range. 3:06 – Surface ships provide endurance, multiple sensors, and command/control capabilities. 3:26 – Nuclear submarines are covert and resilient, able to detect threats far from the force. 4:06 – ASW units use coordinated sensors and platforms to protect high-value assets. 4:30 – Sensors are categorized by range, detectability, acoustic method, and platform type. 5:12 – Submarines primarily use passive sonar, but also have radar, ESM, and visual sensors. 5:30 – Passive sonar uses hull and towed arrays to detect submarines at long range. 6:02 – Detection is influenced by factors like noise levels, operator skill, and ocean conditions. 6:42 – Passive sonar is covert and can classify submarine types by unique acoustic signatures. 7:12 – Passive sonar struggles with quiet or battery-powered subs unless they snorkel. 7:23 – Active sonar, present on subs, ships, and aircraft, is better at detecting quiet subs. 8:22 – Active sonar has limited range, but provides range and bearing data quickly. 8:45 – However, it is easily detected by enemies, sometimes from 2–5× its detection range. 9:05 – Ships also use radar, ESM, and visual sensors to detect submarines near the surface. 9:39 – Aircraft radar, with its altitude advantage, can detect subs from longer distances. 10:01 – ESM detects enemy radar signals but subs minimize emissions to avoid detection. 10:20 – Visual detection is useful for identifying periscopes at short range. 10:42 – Aircraft can deploy active dipping sonar to detect subs a few miles away. 11:02 – Sonobuoys (passive/active) provide critical acoustic data to aircraft and ships. 11:20 – Passive sonobuoys classify subs by noise; directional ones provide bearing too. 11:52 – Aircraft can monitor multiple sonobuoys and relay data to surface ships. 12:11 – Aircraft also use radar, ESM, visual sensors, and magnetic anomaly detection (MAD). 12:33 – MAD detects metal submarines at short range, often used for final localization. 13:14 – FLIR detects heat sources like periscopes, even if visual or radar misses them. 13:50 – Platforms and sensors must be coordinated for effective ASW protection. 14:01 – Example: a task force uses submarines, frigates, and aircraft to guard high-value units. 14:53 – Submarines and frigates use passive sonar in overlapping sectors. 15:01 – Frigates as communication links and helicopter launch platforms. 15:08 – Fixed-wing aircraft monitor sonar barriers to detect approaching enemy subs. 15:29 – Sonar barriers are maintained as the force moves forward. 15:55 – Surface ships conduct passive searches. 16:21 – Aircraft may shift from barrier monitoring to responding to contacts. 16:45 – Helicopters assist with localization and attack. 17:02 – Passive sensors are positioned to detect threats in time for aircraft to respond. 17:20 – Aircraft also perform independent searches for added depth. 17:29 – Submarines are placed in key sectors to maximize their detection strength. 17:38 – Surface ships coordinate and integrate ASW with other warfare functions. 18:01 – Coordinated ASW overcomes individual platform limitations using teamwork. 18:05 – Success depends on early detection followed by rapid and decisive attack.
