SLIDE 4 ‐ Key Events in Manned Underwater Craft Alexander the Great Reportedly Descends in a Diving Bell Syllabus notes for lecture: HISTORICAL DEVELOPMENT OF SUBMARINE ATMOSPHERE CONTROLS Dr. Jeff McClellen, CAPT MC USN, Bureau of Medicine and Surgery SLIDE 4 ‐ Key events in manned underwater craft Alexander the Great reportedly descends in a diving bell. (332 BCE) Van Drebbel submerges oared craft to 15 ft in Thames; heats saltpeter to evolve O2 and absorb CO2. (1624) Von Treileben uses diving bell to salvage cannon from Vasa in Stockholm harbor. (1640‐45) Bushnell’s Turtle unsuccessfully attacks HMS Eagle in New York harbor. (1776) Fulton operates submarine Nautilus in Seine for one hour but fails to obtain support from Napoléon. (1801) CSS H. L. Hunley successfully attacks and sinks USS Housatonic with a spar torpedo, but is lost in the process. (1864) Intelligent Whale built (1863) but has unsuccessful trial for USN. (1872) Holland’s Plunger ordered by USN, but abandoned by Holland after he concludes that steam power is impracticable for submarines (1895). SLIDE 5 – U.S. Submarine Development: John Patrick Holland, immigrant/inventor/American John P. Holland born in County Clare, Ireland and emigrated to New Jersey. His first submarine design (Holland I) was submitted to USN and rejected in 1875. Holland’s subsequent were efforts funded by the Fenian Brotherhood after being turned away by U.S. Navy. Holland II launched in 1881, it boasted a 9” pneumatic gun and was propelled by a 2‐stroke Brayton engine submerged. As it consumed air from the compartment, range was extremely limited. Holland extended this range by installing a compressed air tank. Soon after, Holland and the Fenians parted company on bad terms over the issue of payment. They seized Holland II and towed it off to Connecticut. Later dubbed the “Fenian Ram”, the Fenians had no one who know how to operate the craft. Holland would not tell them, it sat in a barn for years until it was put on display in Madison Square Gardens to raise funds for survivors of the Easter Uprising. Holland VI was launched in 1897, purchased by the U.S. Navy and commissioned as USS Holland (SS‐1) in 1900. A contract for 5 additional units was signed with a yard in Elizabeth, NJ; this organization ultimately became the Electric Boat Company. Holland’s design incorporates many basics features of modern submarines: internal combustion engine for surface propulsion and charging a large storage battery, which in turn is used to power an electric motor for submerged operations, internally loaded torpedo tubes and hydroplane control surfaces. SLIDE 6 – Submarine technical research as it related to Atmosphere Control in the pre‐WW2 period Very short duration dives typically lasting about 6 hours. Submerge when enemy comes within visual range. Surface when compartment air becomes foul. Expectation is for submarine to defend harbors or coast, or nearby ‘choke points’, as they have neither speed nor endurance. Think of as a smart, somewhat mobile mine field. L‐class submarines deployed to Bantry Bay, Ireland during WW1 and served with the Royal Navy. Transited Atlantic by way of Azores with ‘mother ship’ escort. Conducted 8‐10 day patrols though the end of the war—this was well beyond their anticipated capabilities. The S‐class, built in the 1920’s, consisting of 51 vessels constructed by 3 different builders, incorporated much learned from US, British and German WW1 operations. Improved, but with limitations in speed, weapons load, endurance and habitability. No air conditioning. These were quickly relegated to 2nd line status as soon as sufficient ‘Fleet Boats’ became available after 1942, but remained in active service through war’s end. Italian researchers (Belli, Torcello ‐ 1908) identify principle components of submarine atmosphere: O2, CO2, H2, SO2 and volatile hydrocarbons. In 1911, their report chemical agents able to produce O2 (‘Oxylithe’)and absorb CO2 (NaO2), By 1911, Germans use caustic potash and soda to absorb CO2. In 1914, USN engages Harvard Medical School to work on CO2 absorbents. They achieve a 17 hour endurance run on a D‐class. Additional work with O2 tanks, caustic potash and soda lime allow for a 48 hour run in USS G‐3. H2 build up during one run led to development of a palladium wire ‘Hydrogen Eliminator’. Hopcalite, with the ability to catalyze the reaction of CO CO2 at room temperature, was discovered at the American University Experimental Station in 1917. The Naval Research Laboratory (NRL) was established in 1923, upon a suggestion by Thomas Edison to President Wilson in 1917. The loss of S‐51 and S‐4 resulted in the establishment of a special Submarine Board by SECNAV to address specific submarine habitability and survivability questions. SLIDE 7 – Submarine Mortality prior to WW2 Pre‐WW2 period notable for submarine losses with All Hands due to material failures, collision or mishap. USS F‐4 sinks in 300 ft off Honolulu Harbor after leaking battery acid corroded hull (1915). 21 souls lost. USS F‐1 sinks after collision in fog, during 48 hour endurance trials, with F‐3 off San Diego (1917). 19 souls lost. Built at Union Iron Works, San Francisco. ex‐USS G‐2 sinks in Two Tree Channel, Niantic, CT (1919). 3 souls lost. USS H‐1 grounded off Magdalena Bay, Mexico then sinks during salvage efforts (1920). Four souls lost. USS S‐5 floods forward torpedo room and settles on bottom off Delaware Capes. Crew is able to raise stern clear of surface, drill a 3” hole and signal with a flag. SS Alanthus and SS General G. W. Goethals render assistance, cutting hole in hull at stern to extract crew (1920). No lives lost. USS S‐48 floods and sinks in 80 feet prior to commissioning (1921). USS O‐5 rammed by SS Abangarez and sinks at outlet to Panama Canal. Raised by Panama Canal Co. crane Atlas, saving two trapped crew members (1923). Three souls lost. USS S‐51 rammed by SS City of Rome and sinks in 130 feet of water off Block Island (1925). Thirty‐three souls lost. USS S‐4 rammed and sunk by USCGC Paulding off Provincetown, MA (1927). Survivors suffocate on bottom. Forty souls lost. USS Squalus founders during sea trials off Isles of Shoals in 243 feet of water. Thirty‐three crew members survive in forward torpedo room and are rescued using the McCann rescue chamber (1939). Twenty‐six souls lost. USS O‐9 flounders during test dive off Isles of Shoals in 450 feet of water (1941). Thirty‐three souls lost. "When the waves of death compassed me / the floods of ungodly men made me afraid; / the bonds of She'ol encircled me; / the snares of death took me by surprise; / in my distress I called upon the Lord, / and cried to my G‐D: / and he heard my voice out of his temple, / and my cry entered into his ears. / Then the earth shook and trembled; /the foundations of heaven moved / and shook because of his anger /...the heavy mass of waters, and thick clouds of the skies /... And the channels of the sea appeared, / the foundations of the world were laid bare, / at the rebuking of the Lord, at the blast at the breath of his nostrils. / He sent from above, he took me; / he drew me out of many waters; / he delivered me from my strong enemy, and from those who hated me; for they were too strong for me. / They surprised me in the day of my calamity: / but the Lord was my stay..." ‐ Samuel 22:5‐19 SLIDE 8 – Analysis of WW2 Morbidity and Mortality Role of Fleet Submarine: “They were to scout out ahead of the fleet and report on the enemy fleet's composition, speed, and course, then they were to attack and whittle down the enemy in preparation for the main fleet action, a titanic gun battle between battleships and cruisers. This was an operational concept born from experience in World War I. In order to operate effectively in this role, a submarine had to have high surface speed, long range and endurance, and a heavy armament.” – Norman Friedman M&M is driven by combat, trauma and accidents.

  • Navy Ship Names: Background for Congress
    Navy Ship Names: Background for Congress (name redacted) Specialist in Naval Affairs December 13, 2017 Congressional Research Service 7-.... www.crs.gov RS22478 Navy Ship Names: Background for Congress Summary Names for Navy ships traditionally have been chosen and announced by the Secretary of the Navy, under the direction of the President and in accordance with rules prescribed by Congress. Rules for giving certain types of names to certain types of Navy ships have evolved over time. There have been exceptions to the Navy’s ship-naming rules, particularly for the purpose of naming a ship for a person when the rule for that type of ship would have called for it to be named for something else. Some observers have perceived a breakdown in, or corruption of, the rules for naming Navy ships. On July 13, 2012, the Navy submitted to Congress a 73-page report on the Navy’s policies and practices for naming ships. For ship types now being procured for the Navy, or recently procured for the Navy, naming rules can be summarized as follows: The first Ohio replacement ballistic missile submarine (SBNX) has been named Columbia in honor of the District of Columbia, but the Navy has not stated what the naming rule for these ships will be. Virginia (SSN-774) class attack submarines are being named for states. Aircraft carriers are generally named for past U.S. Presidents. Of the past 14, 10 were named for past U.S. Presidents, and 2 for Members of Congress. Destroyers are being named for deceased members of the Navy, Marine Corps, and Coast Guard, including Secretaries of the Navy.

    Submarines in the United States Navy - Wikipedia Page 1 of 13 Submarines in the United States Navy There are three major types of submarines in the United States Navy: ballistic missile submarines, attack submarines, and cruise missile submarines. All submarines in the U.S. Navy are nuclear-powered. Ballistic subs have a single strategic mission of carrying nuclear submarine-launched ballistic missiles. Attack submarines have several tactical missions, including sinking ships and subs, launching cruise missiles, and gathering intelligence. The submarine has a long history in the United States, beginning with the Turtle, the world's first submersible with a documented record of use in combat.[1] Contents Early History (1775–1914) World War I and the inter-war years (1914–1941) World War II (1941–1945) Offensive against Japanese merchant shipping and Japanese war ships Lifeguard League Cold War (1945–1991) Towards the "Nuclear Navy" Strategic deterrence Post–Cold War (1991–present) Composition of the current force Fast attack submarines Ballistic and guided missile submarines Personnel Training Pressure training Escape training Traditions Insignia Submarines Insignia Other insignia Unofficial insignia Submarine verse of the Navy Hymn See also External links References https://en.wikipedia.org/wiki/Submarines_in_the_United_States_Navy 3/24/2018 Submarines in the United States Navy - Wikipedia Page 2 of 13 Early History (1775–1914) There were various submersible projects in the 1800s.

We also examined the revised histories issued by the US Coast Guard Historical Center and the US Naval Historical Center, both of which claimed The U-869 the sinking was a result of a depth charge attack by two US Navy vessels in 1945. The conclusion we reached was that the attack by the destroyers was most likely Reexamined, Part on the already-wrecked U-869.

The Loss of the German Submarine Early Theories The most effective and successful branch of the German By John Chatterton, Richie Kohler, and John Yurga Navy in World War II was the U-boat arm. Hitler feared he would lose in a direct confrontation with the Royal Navy, so the German surface fleet largely sat idle at anchor. Meanwhile, the U-boats and their all- volunteer crews were out at sea, hunting down enemy vessels. They sank the merchant vessels delivering the Allies’ much-needed materials of war, and even were able to achieve some success against much larger enemy warships.
