'''''Ro-41''''' was an [[Imperial Japanese Navy]] [[Kaichū type submarine]] of the K6 [[ship class|sub-class]]. Completed and commissioned in November 1943, she served in [[World War II]] and conducted six war patrols, sinking a [[destroyer escort]] {{USS|Shelton|DE-407}} on one of them, before she was sunk in March 1945.

==Design and description==
The submarines of the K6 sub-class were versions of the preceding K5 sub-class with greater range and diving depth.<ref name=cd3/> They [[Displacement (ship)|displaced]] {{Convert|1115|LT|t|0|disp=flip}} surfaced and {{Convert|1447|LT|t|0|disp=flip}} submerged. The submarines were {{convert|80.5|m|ftin|sp=us}} long, had a [[beam (nautical)|beam]] of {{convert|7|m|ftin|sp=us}} and a [[draft (hull)|draft]] of {{convert|4.07|m|ftin|sp=us}}. They had a diving depth of {{convert|80|m|ft|sp=us}}.<ref name=b4>Bagnasco, p. 187</ref>

For surface running, the boats were powered by two {{convert|2100|bhp|lk=in|0|adj=on}} [[diesel engine]]s, each driving one [[propeller shaft]]. When submerged each propeller was driven by a {{convert|600|hp|0|adj=on}} [[electric motor]].<ref name=c5>Chesneau, p. 203</ref> They could reach {{convert|19.75|kn|lk=in}} on the surface and {{convert|8|kn}} underwater. On the surface, the K6s had a range of {{convert|11000|nmi|lk=in}} at {{convert|12|kn}}; submerged, they had a range of {{convert|45|nmi|abbr=on}} at {{convert|5|kn}}.<ref name=cd3/>

The boats were armed with four internal bow {{convert|53.3|cm|in|1|abbr=on|sp=us}} [[torpedo tube]]s and carried a total of ten [[torpedo]]es. They were also armed with a single [[8 cm/40 3rd Year Type naval gun|{{convert|76.2|mm|in|abbr=on}}]] L/40 [[anti-aircraft gun]] and two single [[Type 96 25 mm AT/AA Gun|{{convert|25|mm|in|1|abbr=on}} AA guns]].<ref name=cd3>Carpenter & Dorr, p. 124</ref>

==Construction and commissioning==

''Ro-41'' was [[Keel-laying|laid down]] on 6 October 1942 by [[Mitsubishi Heavy Industries|Mitsubishi]] at [[Kobe]], [[Japan]], with the name '''''Submarine No. 207'''''.<ref name=combinedfleetRo41>{{cite web |url= http://www.combinedfleet.com/RO-41.htm |title=IJN Submarine RO-41: Tabular Record of Movement |first1=Bob |last1=Hackett |first2=Sander |last2=Kingsepp |work=combinedfleet.com |year=2017|access-date=21 September 2020}}</ref> She was [[Ceremonial ship launching|launched]] on 5 May 1943 and was renamed '''''Ro-41''''' that day.<ref name=combinedfleetRo41/> She was completed and [[Ship commissioning|commissioned]] on 26&nbsp;November&nbsp;1943.<ref name=combinedfleetRo41/>

==Service history==

Upon commissioning, ''Ro-41'' was attached to the [[Maizuru Naval District]] and assigned to Submarine [[Squadron (naval)|Squadron]] 11 for workups.<ref name=combinedfleetRo41/> On 5 March 1944, she was reassigned to Submarine Division 34 in the [[6th Fleet (Imperial Japanese Navy)|6th Fleet]].<ref name=combinedfleetRo41/> She departed [[Kure, Hiroshima|Kure]], Japan, that day bound for [[Chuuk Lagoon|Truk]], which she reached on 14 March 1944.<ref name=combinedfleetRo41/>

===First war patrol===

''Ro-41'' got underway from Truk on 17 March 1944 to begin her first war patrol, ordered to intercept the [[battleship]]s of [[United States Navy]] [[Task Group]] 50.10, which the submarine {{ship|Japanese submarine|Ro-42||2}} had sighted.<ref name=combinedfleetRo41/> ''Ro-41'' patrolled southeast of Truk, but did not find any enemy ships.<ref name=combinedfleetRo41/> On 23 March 1944, she received orders to move to a new patrol area east of [[Jaluit Atoll]].<ref name=combinedfleetRo41/> While returning to Truk on 18 April 1944, she and the submarines {{ship|Japanese submarine|Ro-106||2}} and {{ship|Japanese submarine|Ro-115||2}} were ordered to intercept an [[Allies of World War II|Allied]] [[task force]] Japanese forces had sighted south of Truk, but she was ordered back to Truk on 19 April 1944 before she found any Allied ships.<ref name=combinedfleetRo41/>

===Second war patrol===

''Ro-41'' began her second war patrol on 23 April 1944, departing Truk to head for a patrol area north of [[Jayapura|Hollandia]], [[New Guinea]].<ref name=combinedfleetRo41/> On 26 April 1944, she was reassigned to Submarine Group B and ordered to move to the vicinity of [[Mereyon Island]] at [[Woleai]] in the [[Caroline Islands]] to intercept an Allied task force.<ref name=combinedfleetRo41/> She found no Allied ships, and departed her patrol area on 2 May 1944.<ref name=combinedfleetRo41/> After calling at [[Saipan]] from 7 to 10 May 1944, she headed for Truk, which she reached on 13 May 1944.<ref name=combinedfleetRo41/>

===Kusaie supply run===

U.S. Navy forces received [[Ultra (cryptography)|Ultra]] intelligence information that ''Ro-41'' would depart Truk at 13:00 on 24 May 1944 to make a supply run to [[Kosrae|Kusaie]], where she was scheduled to arrive on 28 May 1944 at 16:30. The [[destroyer]] {{USS|Eaton|DD-510}} got underway from the anchorage at Jaluit Atoll to intercept ''Ro-41''.<ref name=combinedfleetRo41/> The [[destroyer escort]]s {{USS|Greiner|DE-37}} and {{USS|Sanders|DE-40}} later joined ''Eaton''.<ref name=combinedfleetRo41/>

''Ro-41'' left Truk on 24 May 1944 as scheduled and set course for Kusaie with a cargo of 12 [[metric ton]]s of [[rice]].<ref name=combinedfleetRo41/> She arrived south of Kusaie on the morning of 30 May 1944 and approached the harbor at [[Utwe|Utwa]].<ref name=combinedfleetRo41/> After dark, she surfaced and contacted the Japanese garrison of Kusaie, but her lookouts soon reported the arrival of three American ships — presumably ''Eaton'', ''Greiner'', and ''Sanders'' — which they identified as a destroyer and two [[patrol boat]]s.<ref name=combinedfleetRo41/> The U.S. ships appeared not to notice ''Ro-41'', but when an Allied [[Maritime patrol aircraft|patrol plane]] also arrived on the scene, ''Ro-41'' withdrew.<ref name=combinedfleetRo41/> The three American ships had left the area by around 17:00 [[Japan Standard Time]], and ''Ro-41'' entered the harbor at Utwa and began to unload her cargo, but after about 15 minutes the three ships appeared again.<ref name=combinedfleetRo41/> ''Ro-41''′s crew also noted flights by Allied patrol aircraft, but the submarine went unnoticed and the Japanese managed to unload her cargo on 31 May 1944 during a lull in the flights.<ref name=combinedfleetRo41/> ''Ro-41''′s [[commanding officer]] sent a message to Truk offering his opinion that the Allied activity surrounding ''Ro-41''′s visit to Kusaie indicated that the Allies were decrypting and reading coded Japanese signals. In response the Japanese drastically reduced communications with the garrison on Kusaie, pending the issuance of new codes, and ordered the submarine {{ship|Japanese submarine|I-5||2}}, which was headed to Kusaie, to divert to [[Pohnpei|Ponape]].<ref name=combinedfleetRo41/>

Meanwhile, ''Ro-41'' departed Kusaie on 1 June 1944 and moved to a patrol area {{convert|10|nmi}} west of Jaluit Atoll, and on 6 June 1944, the U.S. Navy destroyer escort {{USS|Steele|DE-8}} arrived off Kusaie in a belated attempt to intercept her there.<ref name=combinedfleetRo41/> ''Ro-41''′s sound operator reported hearing the propeller noises of an Allied [[convoy]] west of Jaluit on 12 June 1944, but ''Ro-41'' did not intercept the convoy.<ref name=combinedfleetRo41/>

===Marianas campaign===

On 13 June 1944 the [[Combined Fleet]] activated Operation A-Go for the defense of the [[Mariana Islands]], and that day the commander of the 6th Fleet, [[Vice Admiral]] [[Takeo Takagi]], ordered all available Japanese submarines, including ''Ro-41'', to deploy east of the Marianas.<ref name=combinedfleetRo41/> The [[Marianas campaign]] began with the [[Battle of Saipan|U.S. invasion]] of [[Saipan]] on 15 June 1944,<ref name=combinedfleetRo41/> and on 16 June the 6th Fleet ordered most of the submarines, again including ''Ro-41'', to withdraw from the Marianas.<ref name=combinedfleetRo41/>

===July–September 1944===
On 22 June 1944, ''Ro-41'' received orders to return to Japan and rendezvous with the [[submarine tender]] {{ship|Japanese submarine tender|Tsukushi Maru||2}} in the western [[Seto Inland Sea]] for repairs and provisions.<ref name=combinedfleetRo41/> After stopping in the western Seto Inland Sea on 4 July 1944, she continued on to [[Sasebo]], which she reached on 5 July 1944.<ref name=combinedfleetRo41/> At Sasebo, she began repairs and an overhaul which probably included the installation of a Type 13 air-search [[radar]] and a Type 22 surface-search radar.<ref name=combinedfleetRo41/>

===Third war patrol===
On 15 September 1944, U.S. forces landed [[Battle of Peleliu|on Peleliu]] and [[Battle of Angaur|on Angaur]] in the [[Palau Islands]], and on 18 September, with her repairs and overhaul complete, ''Ro-41'' got underway from Kure to begin her third war patrol, assigned a patrol area in the Palaus east of the [[Philippine Islands]].<ref name=combinedfleetRo41/> On 24 September 1944, she received orders to move to the [[Morotai]] area.<ref name=combinedfleetRo41/> She was {{convert|35|nmi}} east of Morotai on 3 October 1944 when at 08:07 she fired all four of her remaining torpedoes at the U.S. Navy [[escort aircraft carrier]]s {{USS|Midway|CVE-63}} and {{USS|Fanshaw Bay|CVE-70}}.<ref name=combinedfleetRo41/> ''Ro-41''′s crew heard two explosions, and her commanding officer believed that she had sunk one of the carriers and damaged the other.<ref name=combinedfleetRo41/> In fact, her torpedoes missed both carriers, although one hit the [[destroyer escort]] {{USS|Shelton|DE-407}} in the [[stern]].<ref name=combinedfleetRo41/>

Another destroyer escort, {{USS|Richard M. Rowell|DE-403}}, [[Depth charge|depth-charged]] ''Ro-41'', but ''Ro-41'' escaped.<ref name=combinedfleetRo41/> ''Richard M. Rowell'' then took off ''Shelton''′s crew.<ref name=combinedfleetRo41/> After an aircraft from ''Midway'' detected a submarine and dropped a bomb and a dye marker at its location,<ref name=combinedfleetRo41/> ''Richard M. Rowell'' attacked and sank the submarine with [[Hedgehog (weapon)|Hedgehog]] projectiles.<ref name=combinedfleetRo41/> It later became apparent that the submarine she mistakenly sank was {{USS|Seawolf|SS-197}}.<ref name=combinedfleetRo41/> ''Shelton'', meanwhile, was taken under [[Towing|tow]], but [[capsize]]d and sank at {{coord|02|32|N|129|13|E|name=USS ''Shelton''}}.<ref name=combinedfleetRo41/>

On 10 October 1944, two [[Kanoya]]-based [[Yokosuka D4Y|Yokosuka D4Y ''Suisei'']] ("Comet"; [[World War II Allied names for Japanese aircraft|Allied reporting name]] "Judy") [[Reconnaissance aircraft|reconnaissance planes]] reported a U.S. force of three [[aircraft carrier]]s and two [[destroyer]]s southeast of [[Okinawa Island|Okinawa]] steaming northeast, which the Japanese believed to be part of U.S. Navy [[Task Force 38]].<ref name=combinedfleetRo41/> ''Ro-41'' and the submarines {{ship|Japanese submarine|Ro-43||2}} and {{ship|Japanese submarine|Ro-46||2}} were ordered to intercept the ships.<ref name=combinedfleetRo41/> ''Ro-41'' did not find the carriers, and she returned to Kure on 14 October 1944.<ref name=combinedfleetRo41/> She erroneously received credit for sinking one aircraft carrier during her patrol.<ref name=combinedfleetRo41/>

===Fourth war patrol===
''Ro-41'' was reassigned to Submarine Group B on 18 October 1944.<ref name=combinedfleetRo41/> On 20 October, the [[Philippines campaign (1944–1945)|Philippines campaign]] and the [[Battle of Leyte]] began when U.S. forces landed on [[Leyte]] in the Philippine Islands, and that day ''Ro-41'' got underway from Kure to begin her fourth war patrol, bound for a patrol area in the [[Philippine Sea]] east of [[Samar]].<ref name=combinedfleetRo41/> The Japanese naval reaction to the invasion resulted in the [[Battle of Leyte Gulf]], which lasted from 23 to 26 October 1944, but she saw no action in the battle. She sighted a U.S. aircraft carrier escorted by several destroyers east of Samar on 27 October 1944.<ref name=combinedfleetRo41/> On 31 October 1944 she and the submarine {{ship|Japanese submarine|Ro-43||2}} received orders to patrol in the [[San Bernardino Strait]] between [[Luzon]] and [[Samar]] and report and attack any Allied forces attempting to interfere with Japanese [[convoy]]s bringing supplies and reinforcements from [[Manila]] to Leyte,<ref>{{cite web |url= http://www.combinedfleet.com/RO-43.htm |title=IJN Submarine RO-43: Tabular Record of Movement |first1=Bob |last1=Hackett |first2=Sander |last2=Kingsepp |work=combinedfleet.com |year=2017|access-date=23 September 2020}}</ref> and she was east of [[Legaspi, Cagdianao|Legaspi]] on 7 November 1944 when she made sound contact on a westbound Allied task force.<ref name=combinedfleetRo41/> Ordered back to Japan on 8 November 1944, she made sound contact on a westbound Allied [[convoy]] at 02:40 on 12 November before arriving at Maizuru on 18 November 1944.<ref name=combinedfleetRo41/>

===Fifth war patrol===
''Ro-41'' departed Tokuyama on 24 December 1944 for her fifth war patrol, assigned a patrol area northeast of the Philippine Islands.<ref name=combinedfleetRo41/> By 4 January 1945 she was operating west of [[Luzon]].<ref name=combinedfleetRo41/> U.S. forces entered [[Lingayen Gulf]] and U.S. forces [[Invasion of Lingayen Gulf|landed on Luzon]] on 9 January 1945, but ''Ro-41'' did not engage any Allied forces during her patrol. She arrived at Kure on 31 January 1945.<ref name=combinedfleetRo41/>

===Sixth war patrol===

On 7 March 1945, ''Ro-41'' arrived Maizuru, then departed the same day bound for Kure.<ref name=combinedfleetRo41/> She got underway from Kure on 10 March 1945 to carry supplies to Truk, but on 13 March received orders to abort her supply run and return to Japan so that she could take part in an interception of U.S. Navy [[Task Force 58]].<ref name=combinedfleetRo41/> After an overnight stay at Kure from 15 to 16 March 1945, she moved on to [[Saeki District, Hiroshima|Saeki]].<ref name=combinedfleetRo41/> On 18 March 1945, she departed Saeki as the first of a force of submarines that also included {{ship|Japanese submarine|I-8||2}}, {{ship|Japanese submarine|Ro-49||2}}, and {{ship|Japanese submarine|Ro-56|1944|2}} with orders to attempt to intercept the damaged U.S. aircraft carrier {{USS|Franklin|CV-13}}.<ref name=combinedfleetRo41/>

The U.S. Navy submarine {{USS|Kete|SS-369}} disappeared after transmitting a routine weather report south of [[Kyushu]] while proceeding east on 20 March 1945 while ''Ro-41'' was in the area heading south, and some historians have credited ''Ro-41'' with sinking ''Kete''.<ref name=combinedfleetRo41/> ''Ro-41'' never reported sinking, or even sighting, an enemy submarine, so it seems unlikely that she sank ''Kete''.<ref name=combinedfleetRo41/>

On 22 March 1945, ''Ro-41'' was {{convert|320|nmi}} east of Okinawa when she transmitted a message reporting that she had sighted an enemy destroyer.<ref name=combinedfleetRo41/> The Japanese never heard from her again.<ref name=combinedfleetRo41/>

===Loss===

Later on 22 March 1945, the destroyer {{USS|Haggard|DD-555}} was operating as a picket {{convert|12|nmi}} ahead of Task Force 58 when her radar detected a vessel on the surface at a range of {{convert|25,000|yd|m|sigfig=3}} at 23:42.<ref name=combinedfleetRo41/> She and the destroyer {{USS|Uhlmann|DD-687}} closed the range.<ref name=combinedfleetRo41/> The contact disappeared from radar, indicating a diving submarine, but ''Haggard'' detected it on [[sonar]] and attacked it with depth charges.<ref name=combinedfleetRo41/> Shortly before midnight, the submarine [[broach (nautical)|broach]]ed off ''Haggard''′s [[Port and starboard|port]] beam, and ''Haggard''′s [[Bofors 40 mm Automatic Gun L/60|Bofors 40 mm gun]]s opened fire on its [[conning tower]].<ref name=combinedfleetRo41/> ''Haggard'' turned hard to port and rammed the submarine on its starboard side abaft its conning tower.<ref name=combinedfleetRo41/> On 23 March 1945, the submarine sank by the stern at {{coord|22|57|N|132|19|E|name=''Ro-41''}} shortly after midnight, leaving no survivors.<ref name=combinedfleetRo41/> Having suffered heavy [[Bow (ship)|bow]] damage while ramming the submarine, ''Haggard'' proceeded to the fleet anchorage at [[Ulithi Atoll]] for repairs, accompanied by ''Uhlmann''.

The submarine ''Haggard'' sank probably was ''Ro-41''.<ref name=combinedfleetRo41/> On 15 April 1945, the Imperial Japanese Navy declared her to be presumed lost in the Okinawa area with all 82 hands.<ref name=combinedfleetRo41/> She was stricken from the Navy list on 25 May 1945.<ref name=combinedfleetRo41/>
