Ro-60, originally namedSubmarine No. 59, was anImperial Japanese NavyType Lsubmarine of the L4 subclass. She was in commission from 1923 to 1934 and from 1940 to 1941. BeforeWorld War II, she served in the waters ofJapan. During World War II, she took part in theBattle of Wake Island in December 1941, and was damaged by an F4F-3 Wildcat during that battle. The submarine wrecked three weeks later trying to make it back to base, running aground on a reef and was abandoned. All the crew were rescued by a Japanese vessel. Later in the war the vessel exploded after being strafed, scattering fragments of the vessel on that reef.
The submarines of the Type L4 subclass were copies of the Group 3 subclass of the BritishL-class submarine built under license in Japan.[1] They were slightly larger and had two moretorpedo tubes than the preceding submarines of the L3 subclass.[1] Theydisplaced 1,004 tonnes (988 long tons) surfaced and 1,322 tonnes (1,301 long tons) submerged. The submarines were 78.39 meters (257 ft 2 in) long and had abeam of 7.41 meters (24 ft 4 in) and adraft of 3.96 meters (13 ft 0 in). They had a diving depth of 60 meters (197 ft).
For surface running, the submarines were powered by two 1,200-brake-horsepower (895 kW)Vickersdiesel engines, each driving onepropeller shaft. When submerged, each propeller was driven by an 800-shaft-horsepower (597 kW)electric motor. They could reach 15.7knots (29.1 km/h; 18.1 mph) on the surface and 8.6 knots (15.9 km/h; 9.9 mph) underwater. On the surface, they had a range of 5,500nautical miles (10,200 km; 6,300 mi) at 10 knots (19 km/h; 12 mph); submerged, they had a range of 80 nmi (150 km; 92 mi) at 4 knots (7.4 km/h; 4.6 mph).
The submarines were armed with six internal 533 mm (21 in)torpedo tubes, all in thebow, and carried a total of twelve6th Year Type torpedoes. They were also armed with a single76.2 mm (3 in)deck gun and a 6.5 mmmachine gun.
Ro-60 waslaid down asSubmarine No. 59 on 5 December 1921 byMitsubishi atKobe,Japan.[2][3]Launched on 22 December 1922,[2][3] she was completed andcommissioned on 17 September 1923.[2][3]
Upon commissioning,Submarine No. 59 was assigned to theSasebo Naval District.[2][3] On 9 February 1924, she was reassigned to Submarine Division 26 — in which she spent the remainder of her career — and to theSasebo Defense Division.[2][3] On 1 April 1924, Submarine Division 26 was reassigned to SubmarineSquadron 1 in the1st Fleet.Submarine No. 59 was renamedRo-60 on 1 November 1924.[2][3]
On 1 December 1925, Submarine Division 26 was reassigned to Submarine Squadron 2 in the2nd Fleet in theCombined Fleet.[2] On 1 March 1926,Ro-60 and the submarinesRo-57,Ro-58,Ro-59,Ro-61,Ro-62,Ro-63,Ro-64, andRo-68 departedSasebo, Japan, bound forOkinawa, which they reached the same day.[2][4][5][6][7][8][9][10][11] The nine submarines got underway from Okinawa on 30 March 1926 for a training cruise inChinese waters offShanghai andAmoy which concluded with their arrival atMako in thePescadores Islands on 5 April 1926.[2][4][5][6][7][8][9][10][11] They departed Mako on 20 April 1926 for the return leg of their training cruise, operating off China nearChusan Island, then returned to Sasebo on 26 April 1926.[2][4][5][6][7][8][9][10][11]
On 15 December 1926, the Submarine Division 26 returned to the Sasebo Naval District and the Sasebo Defense Division.[2] On 27 March 1927,Ro-60,Ro-61,Ro-62,Ro-63,Ro-64, andRo-68 departedSaeki Bay, Japan, for a training cruise offQingdao, China, which they concluded with her arrival atSasebo, Japan, on 16 May 1927.[2][7][8][9][10][11]Ro-60 was decommissioned on 10 February 1928 and placed in Third Reserve at Sasebo.[2][3]
Ro-60 was recommissioned on 20 September 1928 and resumed active service in Submarine Division 26 in the Sasebo Defense Division in the Sasebo Naval District.[3] On 10 December 1928, the division again was assigned to Submarine Squadron 1 in the 1st Fleet.[2] On 1 December 1930, it returned to the Sasebo Naval District, and served in the Sasebo Defense Division again from that date until 15 November 1933.[2] On 1 June 1934,Ro-60 was decommissioned and placed in Second Reserve at Sasebo,[3] and while in Second Reserve was assigned to the Sasebo Guard Squadron from 15 November 1934 to 15 November 1935.[2] She moved to Third Reserve on 15 December 1938[2] and to Fourth Reserve on 15 November 1939.[2]
Ro-60 again was recommissioned on 15 October 1940,[3] and on 15 November 1940 Submarine Division 26 was reassigned to Submarine Squadron 7 in the4th Fleet in the Combined Fleet.[2] When the Imperial Japanese Navy deployed for the upcomingconflict in the Pacific,Ro-60 was atKwajalein in theMarshall Islands.[3] She received the message "ClimbMount Niitaka 1208" (Japanese:Niitakayama nobore 1208) from the Combined Fleet on 2 December 1941, indicating that war with theAllies would commence on 8 December 1941Japan time,[3] which was on 7 December 1941 on the other side of theInternational Date Line inHawaii, where Japanese plans called for the war to open with theirattack on Pearl Harbor.
Ro-60 was with the other submarines of Submarine Division 26 —Ro-61 andRo-62 — at Kwajalein when Japan enteredWorld War II on 8 December 1941,Kwajalein time.[3] The three submarines were placed on "standby alert" that day asUnited States Marine Corps forces onWake Island threw back the first Japanese attempt to invade theatoll.[3] On 12 December 1941,Ro-60 andRo-61 got underway from Kwajalein to support a second, heavily reinforced Japanese attempt to invade Wake Island;[3][12]Ro-62 followed on 14 December 1941.[13]
Ro-60 was on the surface 25 nautical miles (46 km; 29 mi) southwest of Wake at around 16:00 local time on 21 December 1941 when a U.S. Marine CorpsF4F Wildcatfighter ofMarine Fighter Squadron 211 (VMF-211) attacked her,strafing her and dropping two 100-pound (45.4 kg) bombs.[3]Ro-60 crash-dived, but the attack damaged herperiscopes and several of her diving tanks.[3] After she resurfaced that night and her crew inspected her damage, hercommanding officer decided that she no longer could dive safely.[3] TheBattle of Wake Island ended as Wake Island fell to the Japanese on 23 December 1941, and that dayRo-60 andRo-62 received orders to return to Kwajalein.[3]
As she was approachingKwajalein Atoll in bad weather in the predawn darkness of 29 December 1941,Ro-60 went off course and ran hard aground on areef north of the atoll at 02:00 at09°00′N167°30′E / 9.000°N 167.500°E /9.000; 167.500 (Ro-60), damaging herpressure hull and splitting herstarboard diving tanks open.[3] At about 13:00, the commander of Submarine Squadron 7 arrived on the scene from Kwajalein aboard hisflagship, thesubmarine tenderJingei, to supervise rescue andsalvage operations personally.[3] Pounded by high surf,Ro-60 incurred additional damage and took on such a heavy list that her crew destroyed her secret documents and abandoned ship.[3]Jingei rescued all 66 members of her crew.[2][3]
The Japanese struckRo-60 from the Navy list on 15 February 1942.[3] At some point later in World War II, an unidentified aircraft strafed her wreck, detonatingRo-60′storpedoes and blowing the wreck apart.[3]Divers who later visited the site found her wreckage strewn all over the reef, with her aft section lying against the reef, her forward section lying 200 yards (180 m) ahead of her stern, herconning tower 150 yards (140 m) from the forward section, and her deck gun 560 yards (510 m) beyond that.[3]
