78-485: A Ridgway 300 kW (400 hp) electric generator , was provided for charging batteries or for additional diesel-electric propulsion power. A more successful propulsion improvement in V-4 was the replacement of earlier submarines' pairs of 60- cell batteries with a pair of 120-cell batteries, thus doubling the available voltage to the electric motors when submerged. This battery configuration would be standard until

117-404: A 150 kW (200 hp) GM Winton 4-268A. She was also fitted with a Torpedo Data Computer (lack of which likely inhibited her ability to score with torpedoes), new electronics, and two external stern torpedo tubes on the after casing, along with two stern deck stowage tubes. It appears she was not fitted with bow external torpedo tubes, as were Narwhal and Nautilus , as photos taken after

156-406: A United States plane from Midway. Argonaut ' s dehumidifiers were ineffective at preventing condensation, which caused electrical fires, making various pieces of electrical machinery inoperative. Three crewmen were sick with high fevers, but President Roosevelt's mention of Argonaut ' s contribution to the war effort in a radio speech encouraged Barchet to resist the temptation to abort

195-432: A beautiful Coney Island concessionaire. In this film she appeared as the 'U-200.' Suicide Fleet starred William Boyd, who later found fame as Hopalong Cassidy, and featured a very young Ginger Rogers as the love interest in one of her first featured roles. V-4 was renamed Argonaut on 19 February 1931, and redesignated SM-1 (submarine, minelayer) on 1 July. On 30 June 1932, she arrived at Pearl Harbor , where she

234-432: A brief stop, proceeded to Mare Island Naval Shipyard for major overhaul. While there, her diesels were replaced with General Motors Winton 12-258Ss totaling 4,800 hp (3,600 kW) with hydraulic drive through reduction gears, and her minelaying gear was removed to prepare for conversion to a troop transport submarine. The auxiliary diesel generator was replaced by a 300 kW (400 hp) GM Winton 8-268A and

312-543: A minelayer, and built at a cost of US$ 6,150,000, V-4 was the first and only such specialized type ever built by the United States. She had four torpedo tubes forward and two minelaying tubes aft. At the time of construction, V-4 was the largest submarine ever built in the U.S., and was the largest in U.S. Navy service for 30 years. Her minelaying arrangements were "highly ingenious, but extremely complicated", filling two aft compartments. A compensating tube ran down

351-452: A separate United States Naval Academy curriculum for naval constructors and steam engineers; and the academy offered parallel tracks for cadet-midshipmen and cadet-engineers. Shipboard commanding officers became uncomfortable with their increasing dependency on the skills and advice of subordinates trained in matters unfamiliar to them; so a common naval academy curriculum was re-instituted in 1882, and Engineer Corps officers were merged into

390-575: The Alabama , as well as the gunboats which supported Grant before Fort Donelson and Vicksburg. In 1862, Congress recognized the importance of engineering by creating the Bureau of Steam Engineering. "When Lee surrendered, the United States Navy was the most effective sea power in the world. That position depended upon engineering which, in turn, was based on the skill of Benjamin F. Isherwood, first Chief of

429-756: The Busch-Sulzer engines that propelled earlier V-boats, which were failures. The specially built engines failed to produce their design power, and some developed dangerous crankcase explosions. V-4 was ultimately completed with smaller MAN diesels of 1,400 hp (1,000 kW), compared with 2,350 hp (1,750 kW) for V-5 and V-6 . The smaller diesels were required to allow sufficient space for mine storage. The engine specifications as built were two BuEng -manufactured, MAN -designed direct-drive 6- cylinder 4-cycle main diesel engines , 1,400 hp (1,000 kW) each. A BuEng MAN 6-cylinder 4-cycle auxiliary diesel engine of 450 hp (340 kW), driving

468-528: The GUPPY program following World War II. V-4 and her sisters were slow in diving and, when submerged, were unwieldy and slower than designed. They also presented an excellent target for surface ship sonar and had a large turning radius. For the first time in U.S. submarine construction, the Portsmouth Navy Yard utilized welding during the assembly process. Led by Navy welding expert James W. Owens, welding

507-537: The Monitor ." The Navy's first marine engineer was a civilian appointment in 1836. Congress authorized the establishment of an Engineer Corps in 1842. The 1862 reorganization gave officers of the Engineer Corps their own bureau with dedicated billets to avoid competition from Construction Corps officers (naval architects) in the separated Bureau of Construction and Repair. In 1864 Congress authorized establishment of

546-473: The unrestricted line in 1899. Junior Engineer Corps officers qualified for general line duties at sea, and senior Engineer Corps officers were restricted to shore assignments in their specialties. The restricted line officer concept of "engineering duty only" (EDO) was revived in 1916 when the Engineer Corps officers proved inadequately prepared for the expanded shipbuilding programs of World War I . The EDO designation expanded to include naval architects of

585-611: The Americans' arrival. Snipers were hidden in the trees, and the landing beaches were in front of the Japanese forces instead of behind them as planned. However, by midnight of 18 August, the Japanese garrison of about 85 men was wiped out; radio stations, fuel, and other supplies and installations were destroyed, and all but 30 of the troops had been recovered. Argonaut arrived back in Pearl Harbor on 26 August. Her hull classification symbol

624-402: The Bureau of Steam Engineering. He designed and built engines rugged enough to withstand the shock of combat, as well as ill-treatment by poorly trained operating engineers. He also designed and constructed a well-armed cruiser which was faster than any abroad. In addition, American naval leadership rested upon ingenious civilian engineers and inventors such as John Ericsson, who designed and built

663-514: The Japanese gunboat Ebon Maru in the Bismarck Sea. On 10 January, Argonaut spotted a convoy of five freighters and their escorting destroyers  – Maikaze , Isokaze , and Hamakaze  – returning to Rabaul from Lae. By chance, a United States Army Air Forces (USAAF) aircraft – which was out of bombs – was flying overhead and witnessed Argonaut 's attack. A crewman on board

702-531: The West Coast. In 1931, the V-4 was heavily featured in Seas Beneath , an American action film directed by John Ford. The V-4 was repainted to appear as a World War I German submarine, the fictional 'U-172'. Argonaut also appeared as a German World War I U-boat in the post-Code 1931 film Suicide Fleet , about three US Navy sailors on a schooner submarine decoy Q-ship and their liberty adventures pursuing

741-441: The center of the two spaces, to make up for the lost weight as mines were laid, as well as to store eight additional mines. The other mines were racked in three groups around this tube, two in the fore compartment, one aft, with a hydraulically driven rotating cage between them. Mines were moved by hydraulic worm shafts, the aft racks connecting directly to the launch tubes, which had vertically sliding hydraulic doors (rather than

780-454: The former Construction Corps when the two Corps were merged into the Bureau of Ships in 1940. The consolidation with BuEng into BuShips had its origins when USS  Anderson , first of the Sims -class destroyers to be delivered, was found to be heavier than designed and dangerously top-heavy in early 1939. It was determined that an underestimate by BuEng of the weight of a new machinery design

819-708: The outbreak of the Civil War. The Navy had to blockade a ‘coastline stretching over 3,000 miles from the Potomac to the Mexican border. It had to support the Army on the rivers; it had to search out and destroy Confederate raiders. For all these purposes, the steam engine and the engineer were indispensable. On the day of battle, steam engines drove the Monitor and the Merrimack , the Kearsarge and

858-460: The patrol. By trimming the submarine 17 tons heavy, the crew was able to reduce diving time to 52 seconds by skillfully coordinated pumping between fore and aft ballast tanks; but that time was still considered too slow to avoid hostile aircraft. Argonaut successfully rendezvoused with USS  Litchfield at 06:00 20 January 1942, so the destroyer could escort her back to Pearl Harbor. On 22 January 1942, she returned to Pearl Harbor and, after

897-425: The plane saw one destroyer hit by a torpedo , and the destroyers promptly counterattacking. Argonaut 's bow suddenly broke the water at an unusual angle. It was apparent that a depth charge had severely damaged the submarine. The destroyers continued circling Argonaut , pumping shells into her; she slipped below the waves and was never heard from again. One hundred and two officers and men went down with her,

936-757: The possibility of a naval war with Japan in the far western Pacific. This factor, and the implications of the 1922 Washington Naval Treaty, suggested the need for long-range submarine "cruisers", or "strategic scouts", as well as long-range minelayers, for which long endurance, not high speed, was most important. The design was possibly influenced by the German "U-cruisers" of the Type U-139 and Type U-151 U-boat classes, although V-4 , V-5 , and V-6 were all larger than these. V-4 and her near-sisters V-5 ( Narwhal ) and V-6 ( Nautilus ) were initially designed with larger and more powerful MAN-designed diesel engines than

975-738: The refit do not show them. On return to Pearl Harbor, the conversion to a troop transport submarine was "hastily" finished. Argonaut returned to action in the South Pacific in August. Admiral Chester W. Nimitz assigned Argonaut and Nautilus to transport and land Marine Raiders on Makin Island in the Gilbert Islands for the Makin Raid . This move was designed to relieve pressure on American forces that had just landed on Guadalcanal . On 8 August,

1014-418: The two Japanese destroyers shelling Midway. One of the destroyers saw Argonaut as she dived to make a submerged second approach in the bright moonlight; but the destroyer was unable to locate the submerged submarine, and Argonaut was again unable to maneuver into position to launch torpedoes. After being held down all night, Argonaut surfaced at dawn to recharge batteries and was unsuccessfully bombed by

1053-501: The two submarines embarked 120 troops of Companies A and B, 2nd Raider Battalion , and got underway for Makin. Conditions during the transit were unpleasant, and most of the marines became seasick. The convoy arrived off Makin on 16 August, and at 03:30 the next day the Marines began landing. Their rubber rafts were swamped by the sea and most of the outboard motors drowned. The Japanese—either forewarned or extraordinarily alert—were ready for

1092-418: The usual hinged ones of torpedo tubes). Each launch tube was normally loaded with four mines, and a water 'round mines (WRM) tube flooded to compensate as they were laid, then pumped into the compensating tube. Eight mines could be laid in 10 minutes. Following commissioning, V-4 served with Submarine Division 12 based at Newport, Rhode Island . She proved perennially underpowered, but engine replacement

1131-511: The worst loss of life for an American submarine in wartime. Her name was stricken from the Naval Vessel Register on 26 February. Japanese reports made available at the end of the war recorded a depth charge attack followed by gunfire, at which time they "destroyed the top of the sub". On the basis of the report given by the USAAF flier who witnessed the attack in which Argonaut sank, she

1170-507: Was a submarine of the United States Navy , the first boat to carry the name. Argonaut was laid down as V-4 on 1 May 1925 at Portsmouth Navy Yard . She was launched on 10 November 1927, sponsored by Mrs. Philip Mason Sears, the daughter of Rear Admiral William D. MacDougall, and commissioned on 2 April 1928. Although never officially designated as "SS-166", at some point she displayed this number on her conning tower. V-4

1209-727: Was assigned to SubDiv 7. She carried out minelaying operations, patrol duty, and other routine work. In October 1934 and again in May 1939, Argonaut took part in joint Army-Navy exercises in the Hawaiian operating area. Argonaut became the flagship of Submarine Squadron 4 (SubRon 4). The submarine returned to the West Coast in April 1941 to participate in fleet tactical exercises. On 28 November 1941 Argonaut , commanded by Stephen G. Barchet left Pearl Harbor to patrol around Midway Island with USS  Trout as Midway Defense Group 7.2. She

The bell hanging in her steeple comes from Argonaut , and still rings today for services. 5°40′14″S 153°54′56″E  /  5.67056°S 153.91556°E  / -5.67056; 153.91556 Bureau of Steam Engineering "Engineering, both in operating the shipboard machinery and in the design and construction of ships, became critically important with

1287-516: Was changed from SM-1 to APS-1 (transport submarine) on 22 September. She was never formally designated SS-166 , but that hull number was reserved for her and a photo shows she occasionally displayed it. Her base of operations was transferred to Brisbane, Queensland , later in the year. In December, she departed Brisbane under Lieutenant Commander John R. Pierce to patrol the hazardous area between New Britain and Bougainville Island , south of Bismarck Archipelago . On 2 January 1943, Argonaut sank

1326-542: Was credited with damaging a Japanese destroyer on her last patrol. (Postwar, the JANAC accounting gave her none.) Since none of the histories of the three escorting destroyers reports damage on 10 January 1943, the destroyer "hit" may have been a premature explosion . Before her crew left for their third war patrol, they donated Argonaut 's bell. Nearly 20 months after her loss, the Submarine Memorial Chapel

1365-493: Was notified by radio of the Japanese attack on Pearl Harbor when she surfaced a few minutes after sunset on 7 December. Argonaut set general quarters two hours later to investigate naval gunfire around Midway. While designed as a minelayer and not an attack submarine, Argonaut made the first wartime approach on enemy naval forces; but poor maneuverability prevented reaching a suitable position for surfaced torpedo launch against

1404-560: Was postponed by war, and her MAN diesels were a constant source of trouble. In January–February 1929, V-4 underwent a series of trials off Provincetown, Massachusetts . On a trial dive during this period, she submerged to a depth of 318 ft (97 m). This mark was the greatest depth an American submarine had reached up to that time. On 26 February 1929, V-4 was assigned to Submarine Division 20 ( SubDiv  20), and arrived at San Diego, California on 23 March. From there, she participated in battle exercises and made cruises along

1443-589: Was responsible, and that BuC&R did not have sufficient authority to detect or correct the error during the design process. Initially, Acting Secretary of the Navy Charles Edison proposed consolidation of the design divisions of the two bureaus. When the bureau chiefs could not agree on how to do this, he replaced both chiefs in September 1939. The consolidation was finally effected by a law passed by Congress on 20 June 1940. Commanding and senior officers of

1482-467: Was the first of the second generation of V-boats commissioned in the late 1920s, which remain the largest non-nuclear submarines ever built by the United States. V-4 was the behemoth of its class. These submarines were exempt by special agreement from the armament and tonnage limitations of the 1922 Washington Naval Treaty . Her configuration, and that of the following V-5 and V-6 , resulted from an evolving strategic concept that increasingly emphasized

1521-505: Was used in non-critical areas such as the superstructure, piping brackets, and support framing. V-4 ended up being built to a mixed method construction, with both the inner and outer hulls still riveted. Owens was eager to expand the use of welding in ship construction, and its use on V-4 was entirely successful. All subsequent submarines built for the USN used welding to some extent, with the method adopted in whole in 1936. Designed primarily as
