Type C1 submarine
1 x 140mm deck gun
On May 20, 1942 arrives at Truk and the damaged midget submarine is removed and exchanged for HA-24 midget submarine (M24) plus her crew: captain Lt(jg) Katsuhisa Ban and crew PO1c Mamoru Ashibe and departs the same day proceeding southward to Sydney as the flagship of the mission to reconnoiter and launch her midget submarine to attack Allied warships in Sydney Harbor.
Sydney Harbor Attack
On May 31, 1942 at 5:40pm roughly 7.5 miles east of Sydney I-24 launches HA-24 midget submarine (M24). At 2207, all vessels in the harbor are alerted of the presence of an enemy submarine. At 10:50pm USS Chicago spots the HA-17 midget submarine (M24) and fires on it with her AA guns at the same time HA-21 midget submarine (M22) is entering Sydney Harbor.
On June 1, 1942 at 0029, HA-17 fires one torpedo at USS Chicago but it misses and explodes under HMAS Kuttabul killing 21 sailors and damaging the moored Dutch submarine K-IX. Another torpedo runs aground on the east side of Garden Island. The midget sub fails to return from the mission.
On June 3, 1943 I-24 takes up position roughly 35 miles southeast of Norah Head to recover her midget submarine, but it fails to return and is presumed lost. While recharging her batteries on the surface when it spots Australian coastal steamer Age and fires a torpedo that misses and fires four rounds from her 140mm deck gun that also miss. I-24 sees the vessel disappear and claims it as sunk but in fact it was undamaged. Ninty mintes later roughly 27 miles off Sydney I-24 fires two torpedoes Australian merchant Iron Chieftain en route from Newcastle to Whyalla with a cargo of coke and shipyard materials. One torpedo hits her portside amidships. Her heavy load drags her to the bottom in about five minutes.
On June 5, 1942: 17 miles off Wollongong. The I-24 chases the 3, 362-ton Australian merchant ECHUNGA that is enroute from Whyalla to Port Kembla but fails to damage to her.
On June 8, 1942 four miles off Sydney. After midnight, the I-24 surfaces then opens fire with its deck gun at the Sydney Harbour Bridge. Within four minutes, the I-24 fires ten shells at 30-second intervals. None hit the bridge. Only one of the shells explodes and demolishes part of house in the eastern suburbs. The other are duds and cause only minor damage. The Australians turn on their searchlights, but the I-24 crash dives before shore batteries can return fire. The shelling causes no casualties, but some of Sydney's residents panic and flee the city in fear of a Japanese invasion. P-400 Airacobra piloted by Cantello takes off at night to intercept the submarine, but crashes after takeoff.
On June 9, 1942 southeast of Jervis Bay before dawn, I-24 sights the 7,748-ton British merchant ORESTES. Cdr Hanabusa attacks her twice with torpedoes, but they explode prematurely. The I-24 surfaces and shells the merchant with her 140mm deck gun. She scores a single hit, but does not sink ORESTES. Since no fire is visible, Cdr Hanabusa decides to abandon the attack.
