The second '''''I-22''''' was one of five [[Type C submarine|Type C]] [[cruiser submarine]]s of the C1 [[ship class|sub-class]] built of the [[Imperial Japanese Navy]]. During [[World War II]], she operated as the [[mother ship]] for a [[midget submarine]] during the [[attack on Pearl Harbor]] and the [[attack on Sydney Harbour]], supported Japanese forces during the [[Battle of the Coral Sea]], and served in the [[Guadalcanal campaign]]. She was sunk in October 1942.

==Design and description==
The Type C submarines were derived from the earlier KD6 sub-class of the {{sclass|Kaidai|submarine|4}} with a heavier torpedo armament for long-range attacks. They [[Displacement (ship)|displaced]] {{Convert|2554|LT|t|0|disp=flip}} surfaced and {{Convert|3561|LT|t|0|disp=flip}} submerged. The submarines were {{convert|109.3|m|ftin|sp=us}} long, had a [[beam (nautical)|beam]] of {{convert|9.1|m|ftin|sp=us}} and a [[draft (hull)|draft]] of {{convert|5.3|m|ftin|sp=us}}. They had a diving depth of {{convert|100|m|ft|sp=us}}.<ref name=b4>Bagnasco, p. 192</ref>

For surface running, the boats were powered by two {{convert|6200|bhp|lk=in|0|adj=on}} [[diesel engine]]s, each driving one [[propeller shaft]]. When submerged each propeller was driven by a {{convert|1000|hp|0|adj=on}} [[electric motor]]. They could reach {{convert|23.6|kn|lk=in}} on the surface and {{convert|8|kn}} underwater.<ref name=c5>Chesneau, p. 201</ref> On the surface, the ''C1''s had a range of {{convert|14000|nmi|lk=in}} at {{convert|16|kn}}; submerged, they had a range of {{convert|60|nmi|abbr=on}} at {{convert|3|kn}}.<ref name=cd3/>

The boats were armed with eight internal bow {{convert|53.3|cm|in|1|abbr=on|sp=us}} [[torpedo tube]]s and carried a total of 20 [[torpedo]]es. They were also armed with a single [[14 cm/40 11th Year Type naval gun|{{convert|140|mm|in|abbr=on}}/40]] [[deck gun]] and two single or twin mounts for [[Type 96 25 mm AT/AA Gun|{{convert|25|mm|in|0|abbr=on}} Type 96]] [[anti-aircraft gun]]s. They were equipped to carry one [[Type A Kō-hyōteki-class submarine|Type A midget submarine]] aft of the [[conning tower]].<ref name=cd3>Carpenter & Dorr, p. 104</ref>

==Construction and commissioning==
Ordered under the [[3rd Naval Armaments Supplement Programme]] and built by [[Kawasaki Shipbuilding Corporation|Kawasaki]] at [[Kobe]], [[Japan]], ''I-22'' was [[Keel-laying|laid down]] on 25 November 1937 with the name '''''Submarine No. 47'''''.<ref name=combinedfleetI22>{{cite web |url= http://www.combinedfleet.com/I-22.htm |title=IJN Submarine I-22: Tabular Record of Movement |first1=Bob |last1=Hackett |first2=Sander |last2=Kingsepp |work=combinedfleet.com |year=2015|access-date=17 August 2020}}</ref> While she was on the building ways, she was renamed '''''I-22''''',<ref name=combinedfleetI22/> the second submarine of that number, the first ''I-22'' being renumbered {{ship|Japanese submarine|I-122||2}} on 1 June 1938 to make the number ''I-22'' available for her.<ref>{{cite web |url= http://www.combinedfleet.com/I-122.htm |title=IJN Submarine I-122: Tabular Record of Movement |first1=Bob |last1=Hackett |first2=Sander |last2=Kingsepp |work=combinedfleet.com |year=2015|access-date=17 August 2020}}</ref> She was [[Ceremonial ship launching|launched]] on 23 December 1938<ref name=combinedfleetI22/> and was completed and [[Ship commissioning|commissioned]] on 10 March 1941.<ref name=combinedfleetI22/>

==Service history==
===Pre-World War II===
Upon commissioning, ''I-22'' was attached to the [[Yokosuka Naval District]] and assigned to the [[Yokosuka]] Guard Unit Training Squadron.<ref name=combinedfleetI22/> She was reassigned to Submarine Division 3 in Submarine Squadron 1 in the [[6th Fleet (Imperial Japanese Navy)|6th Fleet]] on 15 July 1941.<ref name=combinedfleetI22/>

On 22 October 1941, ''I-22'' moved from [[Saeki District, Hiroshima|Saeki]] to the [[Kure Naval Arsenal]] in [[Kure, Hiroshima|Kure]].<ref name=combinedfleetI22/> At Kure, she became the first submarine to undergo conversion into a [[mother ship]] for a [[Type A Kō-hyōteki-class submarine|Type A]] [[midget submarine]].<ref name=combinedfleetI22/> The submarines {{ship|Japanese submarine|I-16||2}}, {{ship|Japanese submarine|I-18||2}}, {{ship|Japanese submarine|I-20||2}}, and {{ship|Japanese submarine|I-24||2}} also underwent the conversion.<ref name=combinedfleetI22/> On 30 October 1941, ''I-22'' replaced the submarine {{ship|Japanese submarine|I-21||2}} as [[flagship]] of Submarine Division 3.<ref name=combinedfleetI22/>

At the Kure Navy Club in Kure on 17 November 1941, the commander of Submarine Division 3 briefed the [[commanding officer]]s of the five converted submarines on the upcoming [[attack on Pearl Harbor]] and on the role of their submarines in it.<ref name=combinedfleetI22/> He had been designated the commander of the Special Attack Unit, made up of all five submarines, each of which was to launch a Type A midget submarine off [[Pearl Harbor]] so that the midget submarines could participate in the attack.<ref name=combinedfleetI22/> ''I-22'' was to serve as flagship of the Special Attack unit.<ref name=combinedfleetI22/>

On 18 November 1941, the five submarines moved from Kure to the [[Kamegakubi Naval Proving Ground]], where each embarked a Type A midget submarine.<ref name=combinedfleetI22/> At 02:15 on 19 November 1941, the five submarines got underway from Kamegakubi bound for the [[Hawaiian Islands]],<ref name=combinedfleetI22/> taking a direct route that took them south of [[Midway Atoll]].<ref name=combinedfleetI22/> While at sea, they received the message "Climb [[Yu Shan|Mount Niitaka]] 1208" ({{langx|ja|Niitakayama nobore 1208}}) from the [[Combined Fleet]] on 2 December 1941, indicating that war with the [[Allies of World War II|Allies]] would commence on 8 December 1941 [[Japan Standard Time|Japan time]], which was on 7 December 1941 on the other side of the [[International Date Line]] in [[Hawaii]].<ref name=combinedfleetI22/>

===World War II===
====Pearl Harbor====
At 01:10 on 7 December 1941, ''I-22'' reached the launch position for her midget submarine, ''No. 15'', {{convert|9|nmi}} south of the entrance to Pearl Harbor.<ref name=combinedfleetI22/> She launched ''No. 15'' at 01:16.<ref name=combinedfleetI22/> She sighted the silhouettes of two ships resembling [[heavy cruiser]]s at 02:00 and submerged.<ref name=combinedfleetI22/> She heard a heavy explosion at 07:12, followed by a second at 07:13 and a third at 08:18.<ref name=combinedfleetI22/>

''No. 15'' apparently succeeded in penetrating the defenses of Pearl Harbor. At 08:30, while the air attack on the harbor was underway, the [[destroyer minesweeper]] {{USS|Zane|DMS-14}} reported sighting a midget submarine — likely ''No. 15'' — {{convert|200|yd|m|sigfig=2}} astern of the [[repair ship]] {{USS|Medusa|AR-1}}.<ref name=combinedfleetI22/> The [[destroyer minelayer]] {{USS|Breese|DM-18}} next sighted the submarine, followed by the [[seaplane tender]] {{USS|Curtiss|AV-4}}, which opened fire on it, as did ''Medusa'' and the seaplane tender {{USS|Tangier|AV-8}}.<ref name=combinedfleetI22/> The submarine fired a [[torpedo]] at ''Curtiss'', then [[broach (nautical)|broach]]ed.<ref name=combinedfleetI22/> Before it could submerge again, [[M2 Browning|.50-caliber]] [[Machine gun|machine-gun]] fire raked it and a {{convert|5|in|mm|adj=on|sigfig=3}} [[Shell (projectile)|shell]] hit its [[conning tower]], decapitating its commanding officer.<ref name=combinedfleetI22/> Meanwhile, the [[destroyer]] {{USS|Monaghan|DD-354}} had sighted the submarine {{convert|1,200|yd|m|sigfig=2}} off her [[Port and starboard|starboard]] [[Bow (ship)|bow]] and steered toward it, intending to ram it.<ref name=combinedfleetI22/> The submarine turned toward ''Monaghan'' and fired its second and last torpedo, which missed close aboard off ''Monaghan''′s starboard side and exploded on the shore of [[Ford Island]].<ref name=combinedfleetI22/> ''Monaghan'' rammed the submarine, driving it to the bottom of the {{convert|30|ft|m|adj=on|1}} deep harbor, and dropped two [[depth charge]]s which blew the submarine back to the surface.<ref name=combinedfleetI22/> It then sank northwest of Ford Island with the loss of both members of its crew.<ref name=combinedfleetI22/>

At sea, ''I-22'' underwent repeated depth-charge attacks between 09:50 and 12:43, but suffered no damage.<ref name=combinedfleetI22/> She surfaced at 18:06 and made for an area west of [[Lanai]] where plans called for the recovery of the midget submarines.<ref name=combinedfleetI22/> She reached the area at 23:14.<ref name=combinedfleetI22/> When none of the midget submarines arrived, she left at 06:00 on 8 December for an alternative recovery area, where she began a search on the surface for the midget submarines at 18:00, again finding none.<ref name=combinedfleetI22/> The commander of the Special Attack Unit ordered her back to the primary recovery area off Lanai again on 9 December, but there still was no trace of the midget submarines or their crews.<ref name=combinedfleetI22/> At 01:22 on 10 December, she received orders claiming that one of the midget submarines had achieved an unspecified "important victory" during the 7 December attack and instructing both ''I-22'' and ''I-16'' to continue to search for the midget submarines and their crews until dawn on 11 December.<ref name=combinedfleetI22/> ''I-22'' attempted to contact ''No. 15'' by radio on 10 December, and at 18:02 began a search on the surface south of [[Molokai]].<ref name=combinedfleetI22/> Ultimately, none of the five midget submarines returned, and at dawn on 11 December, ''I-22'' was off Lanai when she received orders to suspend the search and join ''I-18'' in bombarding [[Johnston Island]].<ref name=combinedfleetI22/> She departed the Hawaiian Islands.<ref name=combinedfleetI22/>

On 15 December 1941, ''I-22'' approached Johnston Island in a rain [[squall]].<ref name=combinedfleetI22/> She opened fire with her {{convert|140|mm|in|adj=on|sp=us|1}} deck gun from {{convert|5,500|yd|m}} offshore.<ref name=combinedfleetI22/> Her first two rounds bracketed the island.<ref name=combinedfleetI22/> Her third shot set fire to an oil [[storage tank]] that fueled a nearby [[power station]].<ref name=combinedfleetI22/> She fired at the burning tank for ten minutes, hitting several other buildings.<ref name=combinedfleetI22/> One {{convert|140|mm|in|adj=on|sp=us|1}} shell landed astern of the U.S. Navy [[Transport (ship)|transport]] {{USS|William Ward Burrows|AP-6}}, which was [[anchor]]ed inside the [[reef]].<ref name=combinedfleetI22/> Another shell passed over  ''William Ward Burrows''′s [[forecastle]], but the ship suffered no hits.<ref name=combinedfleetI22/> The [[United States Marine Corps]] forces on the island returned fire with {{convert|5|in|mm|adj=on|sigfig=3}} guns, but the Marine gunfire was inaccurate, and ''I-22'' remained on the surface as she departed the area unscathed at {{convert|18|kn}}.<ref name=combinedfleetI22/> She arrived at [[Kwajalein]] on 21 December 1941.<ref name=combinedfleetI22/>

====First war patrol====
On 4 January 1942, ''I-22'' departed Kwajalein in company with ''I-18'' and ''I-24'' on their first war patrols, assigned patrol areas off the Hawaiian Islands.<ref name=combinedfleetI22/> She reached her assigned patrol area southeast of [[Oahu]] on 10 January and operated there uneventfully until either 18 or 20 January 1942, when she set course for the [[Northwestern Hawaiian Islands]] to reconnoiter the [[French Frigate Shoals]] to determine whether U.S. forces were present there.<ref name=combinedfleetI22/> She conducted a brief reconnaissance of the French Frigate Shoals on 24 January 1942, then proceeded to [[Yokosuka]], which she reached on 2 February 1942 in company with ''I-24''.<ref name=combinedfleetI22/>

====February–April 1942====
''I-22'' moved to Kure later in February 1942,<ref name=combinedfleetI22/> and on 10 March 1942 she was reassigned to Submarine Squadron 8.<ref name=combinedfleetI22/> By 15 April 1942, she was assigned to Submarine Division 3 with ''I-21'' and ''I-24'', which together with Submarine Division 14 — consisting of {{ship|Japanese submarine|I-27||2}}, {{ship|Japanese submarine|I-28||2}}, and {{ship|Japanese submarine|I-29||2}} — made up the Eastern Advanced Detachment, which was under the overall command of Submarine Division 3′s commander.<ref name=combinedfleetI22/>

On 15 April 1942, ''I-22'' got underway from Kure bound for [[Chuuk Lagoon|Truk]] along with the other submarines of the detachment.<ref name=combinedfleetI22/> During their voyage, 16 [[United States Army Air Forces]] [[North American B-25 Mitchell|B-25 Mitchell]] [[bomber]]s launched by the aircraft carrier {{USS|Hornet|CV-8}} struck targets on [[Honshu]] in the [[Doolittle Raid]] on 18 April 1942.<ref name=combinedfleetI22/> The detachment received orders that day to divert from its voyage and head east-northeast at flank speed to intercept the U.S. Navy [[task force]] that had launched the strike, but the orders were canceled on 19 April and the submarines resumed their voyage to Truk, which they reached on 24 April 1942.<ref name=combinedfleetI22/>

====Second war patrol====

On 30 April 1942, ''I-22'', ''I-24'', ''I-28'', and ''I-29'' got underway from Truk to form a patrol line southwest of [[Guadalcanal]] in support of [[Operation MO]], a planned Japanese invasion of [[Tulagi]] in the [[Solomon Islands (archipelago)|Solomon Islands]] and [[Port Moresby]] on [[New Guinea]].<ref name=combinedfleetI22/> While they were en route, the [[Battle of the Coral Sea]] began on 4 May 1942 as Allied forces moved to block the  Japanese offensive.<ref name=combinedfleetI22/> As the battle continued, the four submarines arrived in their assigned areas and formed their patrol line on 5 May 1942.<ref name=combinedfleetI22/> While the Japanese seized Tulagi and were turned back from Port Moresby, ''I-22''′s patrol passed quietly.<ref name=combinedfleetI22/> She received orders on 11 May 1942 to return to Truk.<ref name=combinedfleetI22/> While she was en route, the submarine {{USS|Tautog|SS-199}} sighted two Japanese submarines — probably ''I-22'' and ''I-24'' — proceeding separately on the surface and unsuccessfully attacked one of them early on the morning of 17 May 1942, but a few hours later sank ''I-28'', which was trailing ''I-22'' and ''I-24'' on the same course.<ref name=combinedfleetI22/><ref>{{cite web |url= http://www.combinedfleet.com/I-28.htm |title=IJN Submarine I-28: Tabular Record of Movement |first1=Bob |last1=Hackett |first2=Sander |last2=Kingsepp |work=combinedfleet.com |year=2009|access-date=17 August 2020}}</ref> ''I-22'' arrived safely at Truk later that day.<ref name=combinedfleetI22/>

====Attack on Sydney Harbour and fourth war patrol====

On the day she arrived at Truk, ''I-22'' embarked a Type A midget submarine.<ref name=combinedfleetI22/> She got underway in company with ''I-24'' and ''I-27'' on 18 May 1942 bound for [[Sydney]], [[Australia]], to launch a midget submarine attack against ships in [[Sydney Harbour]].<ref name=combinedfleetI22/> During their voyage, the three submarines received reconnaissance reports from ''I-29'', which launched a [[floatplane]] to reconnoiter Sydney Harbour on 23 May 1942, and ''I-21'', whose [[Yokosuka E14Y]]1 ([[World War II Allied names for Japanese aircraft|Allied reporting name]] "Glen") floatplane conducted a reconnaissance flight early on the morning of 29 May 1942 and sighted the heavy cruiser {{USS|Chicago|CA-29}} at Sydney, mistakenly reporting her as a [[battleship]].<ref name=combinedfleetI22/> That day, the commander of the Eastern Advanced Detachment ordered the three submarines to launch the midget submarine attack.<ref name=combinedfleetI22/>

On 30 May 1942, ''I-22'', ''I-24'', and ''I-27'' arrived off Sydney.<ref name=combinedfleetI22/> Between 17:21 and 17:40 on 31 May, each launched her midget submarine to begin what became known as the [[attack on Sydney Harbour]].<ref name=combinedfleetI22/> ''I-22''′s midget, ''M21'', reached the harbor, where the [[patrol boat]] {{HMAS|Yandra}} tried to ram her, then dropped depth charges.<ref name=combinedfleetI22/> ''M21'' survived ''Yandra''′s attack, but when the patrol vessel {{HMAS|Sea Mist}} attacked her off Taylors Bay and disabled her, ''M21''′s two-man crew shot themselves to death.<ref name=combinedfleetI22/> Allied forces later found ''M21'' on the harbor bottom with her motor still running.<ref name=combinedfleetI22/> ''I-24''′s and ''I-27''′s midget submarines also were lost.<ref name=combinedfleetI22/>

''I-22'', ''I-24'', and ''I-27'' loitered off Sydney until 3 June 1942 in the hope of recovering their midget submarines, then gave up hope and departed the area, splitting up to begin anti-shipping patrols.<ref name=combinedfleetI22/> ''I-22'' was tasked to conduct a reconnaissance of [[Wellington]] and [[Auckland]], [[New Zealand]], and [[Suva]] in the [[Fiji Islands]].<ref name=combinedfleetI22/> She carried out a [[periscope]] reconnaissance of Wellington on 8 and 9 June 1942,<ref name=combinedfleetI22/> and on 9 June a New Zealand military post sighted her on the surface in [[Mahinepua Bay]] off the [[Cavalli Islands]], reporting her 337 degrees northeast and {{convert|2.2|nmi}} from the islands at 10:30 and 302 degrees northeast and {{convert|4.5|nmi}} from them at 11:00.<ref name=combinedfleetI22/>  She attacked a small [[Steamship|steamer]] off [[Portland Island (New Zealand)|Portland Island]] at 14:18 on 10 June, but her torpedo passed under the steamer′s hull without exploding and the ship escaped.<ref name=combinedfleetI22/> She reconnoitered [[Hauraki Gulf]] and Auckland after dark that evening,<ref name=combinedfleetI22/> Suva on 17 and 18 June,<ref name=combinedfleetI22/> and Auckland again on 19 June.<ref name=combinedfleetI22/> and arrived at Kwajalein with ''I-21'', ''I-24'', ''I-27'', and ''I-29'' on 25 June 1942.<ref name=combinedfleetI22/> She left Kwajalein on 5 July bound for Yokosuka, which she reached on 11 July 1942.<ref name=combinedfleetI22/>

====Fourth war patrol====
During ''I-22''′s stay at Yokosuka, the [[Guadalcanal campaign]] began on 7 August 1942 with U.S. amphibious landings on [[Guadalcanal]], [[Tulagi]], [[Florida Island]], [[Gavutu]], and [[Tanambogo]] in the southeastern [[Solomon Islands (archipelago)|Solomon Islands]].<ref name=combinedfleetI22/> On 11 September 1942, ''I-22'' departed Yokosuka bound for the Solomon Islands to conduct her fifth war patrol,<ref name=combinedfleetI22/> and while at sea received orders on 15 September 1942 to join a patrol line southwest of [[Rennell Island]].<ref name=combinedfleetI22/> She reported sighting a northbound Allied [[convoy]] {{convert|40|nmi}} southeast of [[Malaita]] on 1 October and reported her position southeast of Malaita on 4 October 1942.<ref name=combinedfleetI22/> She was never heard from again.<ref name=combinedfleetI22/>

====Loss====

At 21:50 [[Greenwich Mean Time]] on 6 October 1942, a U.S. Navy [[Consolidated PBY Catalina|PBY-5A Catalina]] [[flying boat]] flying southwest from [[Henderson Field (Guadalcanal)|Henderson Field]] on Guadalcanal sighted ''I-22'' submerging in the [[Coral Sea]] at {{coord|11|22|S|162|20|E|name=''I-22''}}.<ref name=combinedfleetI22/> The plane dropped four depth charges.<ref name=combinedfleetI22/> Oil and bubbles appeared on the surface, marking the end of ''I-22'' with the loss of all 100 men on board.<ref name=combinedfleetI22/>

On 12 November 1942, the Imperial Japanese Navy declared ''I-22'' to be presumed lost with all hands.<ref name=combinedfleetI22/> She was stricken from the Navy list on 15 December 1942.<ref name=combinedfleetI22/>

After World War II, the U.S. [[Joint Army-Navy Assessment Committee]] officially credited the U.S. Navy [[PT boat]] [[Patrol torpedo bat PT-122|PT-122]] with sinking ''I-22'' off the [[Kumusi River]] on the coast of [[New Guinea]] during the night of 23–24 December 1942.<ref name=combinedfleetI22/> This subsequently was disproved.<ref name=combinedfleetI22/>
