At 1106 launches a strike (second of the day) of 7 B5N2s escorted by 8 A6M2s.
At 1310 these attack the crippled U.S. carrier HORNET, frustrating a tow attempt by heavy cruiser NORTHAMPTON. This strike scores a devastating torpedo hit in the starboard after engine room of the carrier at 1323, knocking out all remaining power and thwarting further salvage attempts. (HORNET is subsequently sunk by destroyers of the Advance Force after failed scuttling attempts by USN destroyers). Two B5N2s and two A6M2s are lost.
At 2100, three radar-equipped Consolidated PBYs armed with bombs and torpedoes attack ZUIKAKU and JUNYO. A near-miss off the starboard beam damages DesDiv 61’s TERUZUKI, but the carriers are not hit.

5 November 1943:
At 0400, the zigzagging task group is picked up on radar in the Bungo Suido by LtCdr (later Admiral) Ignatius. J. "Pete" Galantin's (USNA ’33) USS HALIBUT (SS-232). Identified as 1 ACV, 2 BB, 1 CA and several DDs course 300, 19 knots.
At 0539, Galantin fires six bow torpedoes at JUNYO. At 0540, the first torpedo of the spread hits JUNYO in the starboard quarter. Four men are killed and steering gear is destroyed. The rudder is jammed five degrees right, and there is some damage to the propeller shafts. Stern settles, but flooding and list are minimal. The other five torpedoes miss astern. It appears one of the misses of the first salvo hits YAMASHIRO, which was then on JUNYO's port quarter, but it fails to explode.
At 0543, Galantin fires two stern torpedoes at the carrier but they miss. At 0558, Galantin tries to fire another torpedo at JUNYO but it malfunctions and "runs hot" in the tube. The screen drives away the submarine and emergency repairs continue. At 1541, the carrier signals that despite some vibrations in the shafts she can make turns for 15 knots. However, because of the damaged rudder, she cannot proceed on her own power and TONE has to take her in tow to bring her into Kure.

13 June 1944: Operation "A-GO" - The Battle of the Philippine Sea:
In Tokyo, the CINC, Combined Fleet, Admiral Toyoda Soemu, (33) (former CO of HYUGA), sends out a signal that activates the A-GO plan for the Defense of the Marianas.
At 0900, Ozawa's Mobile Fleet departs Tawi Tawi (less Operation "Kon's" BatDiv 1, CruDiv 5 and screen) for Guimaras near Panay Island, Philippines. JUNYO is in Rear Admiral Joshima Takatsugu's (40) Force "B" also consisting of CarDiv 2's HIYO and RYUHO, BatDiv 1's NAGATO, CruDiv 7's MOGAMI, DesRon 2's HAYASHIMO, DesDiv 4's MICHISHIO.
At 0900 (H-time, 1000 JST), LtCdr (later Cdr) Marshall H. Austin's (USNA '35) USS REDFIN (SS-272) on station outside the anchorage, sights and at 2100 (JST) reports the fleet departing.
14 June 1944:
Guimaras. Refuels from the 2nd Supply Force oilers GENYO and AZUSA MARUs.
15 June 1944:
At 0800, the Mobile Fleet departs Guimaras through the Visayan Sea. At 1622 (H-time/1722 JST), LtCdr (later Captain) Robert Risser's (USNA '34) USS FLYING FISH (SS-229) sights the Mobile Fleet exiting the San Bernardino Strait. At sunset, he surfaces and at 2025 (JST) reports the contact.
Ozawa's forces refuel from the 1st Supply Force oilers HAYUSUI and NICHIEI, KOKUYO and SEIYO MARUs.
Forces “A” and “B” deploy 100 miles behind Vice Admiral Kurita Takeo's (38) former CO of KONGO) Vanguard Force "C.”
17 June 1944:
In the morning CarDiv 2's screen is reinforced by destroyers NOWAKI and YAMAGUMO.
At 1800 CarDiv 2' s screen is reinforced by destroyers SHIGURE, SAMIDARE, AKISHIMO and HAMAKAZE detached from 1st Replenishment tanker group.
At 2000 JST, LtCdr (later Rear Admiral) Herman J. Kossler's (USNA '34) USS CAVALLA (SS-244) sights the Mobile Fleet in the Philippine Sea and at 2245 reports its movement after surfacing later that evening.
18 June 1944:
At 2100, Ozawa splits the Mobile Fleet. Forces “A” and “B” proceed southward. The Vanguard Force “C” proceeds due east.
19 June 1944:
CarDiv 2's 652nd Air Group consists of 53 A6M5 fighters, 27 A6M2 fighter-bombers, 15 Nakajima 'Tenzan' B6N2 “Jill” attack planes, 11 Yokosuka Type 2 'Suisei' D4Y1 “Comet” and 29 D3A2 dive-bombers. CarDiv 2 doesn't take part in the first two airstrikes (So-called Raid I and Raid II.)
At 0950, CarDiv 2's first airstrike (the third of the day) is launched, consisting of 25 A6M2 fighter-bombers, 7 B6N2 torpedo-equipped escorted by 15 A6M5 fighters. During their outbound leg, they are redirected towards a new position but only about 20 aircraft receive the radio-message and duly change their course, the other aircraft, after failing to spot Task Force 58, return to their respective carriers. The airstrike, hence reduced to a mere 20 aircraft, fails to score any hit for the loss of 7 A6Ms.
Ozawa orders a fourth strike to be launched totaling 70 aircraft to which JUNYO contributes 9 D3A2s escorted by 6 A6M5s, the first aircraft taking off at 1015. However, that airstrike is, once again, a complete failure as the planes are instructed to fly to position “15 Ri”, a wrong spot where TF 58 is absent. After circling for 30 minutes in vain, JUNYO's aircraft head to Guam and arrive there at the same time as a USN aircraft raid. In the ensuing air battle, 3 A6M5 and 7 D3A2 are shot down by the F6Fs “Hellcat” for the loss of 6 “Hellcats”.
Meantime, at 1030, JUNYO launches a second wave consisting of 9 D4Y1s escorted by 6 A6M5s. Shortly after taking off, 2 D4Y1 abort mission, due to a faulty landing gear and head to Yap, and one A6M5 experiencing mechanical trouble returns to the carrier. At 1340, the remaining aircraft attack Task Force 58, targeting USS WASP (CV-18) but score no hits. 4 A6M5s and 5 D4Y1s are shot down, the surviving aircraft landing at Guam and at Rota.
To summarize, the Mobile Fleet has launched that day 374 aircraft, including floatplanes, in four raids against Admiral Raymond A. Spruance's (USNA '06) Task Force 58. In the "Great Marianas Turkey Shoot", Ozawa has lost 244 planes in the raids. Spruance has lost 22 aircraft in the fighting including some to flak on Guam. The 652th Air Group is reduced to 46 aircraft – 19 A6M5, 19 A6M2 and 8 B6N2 – to be compared to an initial strength totaling 135 aircraft.
20 June 1944:
On the second day of Battle of the Marianas, TF-58 aircraft attack Ozawa’s Mobile Fleet. JUNYO is attacked around 1750. She is hit on the island against the stack by one or two 250 kg bombs. The smokestack is utterly crushed and goes overboard and the mast shattered. Flying fragments and blast kill many lookouts and signal men, but fortunately do little harm to the bridge. Fires are started in the island superstructure. At the same time numerous near-misses buckles the flight deck and perforates the fantail causing minor flooding in the steering room. Though air operations are stopped, damage is moderate. However, JUNYO lost 53 men killed, almost all of them lookouts and signal men. Three A6Ms are lost for one SBD “Dauntless” shot down by JUNYO’s combat air patrol (CAP). Attempts to standby torpedoed sister-carrier HIYO, but withdraws soon after. At the day’s end, the 652nd Air Group is reduced to about 20~25 aircraft – 11 A6M5s, 5 A6M2, 1 B6N2 and the few aircraft that have landed at Yap, Rota and Guam. Admiral Toyoda orders the Mobile Fleet to retire to Nakagusuku Wan (Bay), Okinawa.

The rockets are armed with multiple incendiary shrapnel charges and a time fuze. The launching crews must wear special protective suits and withdraw prior to each launch. The carrier’s light AA armament consists now of a total of 91 25mm tubes: 57 in 19 triple mounts, four in two twin mounts and 30 single mounts. The carrier is also fitted with one Type 13 air search radar placed on the mast aft of the island.(Note 1)
Departs Kure and arrives at Iwakuni later in the day. There she commences training with her new air group, the 634th Air Group.
11 October 1944:

3 November 1944:
160 miles W of Cape Bolinao, Luzon, Philippines. Lt Cdr (later Admiral/CINCPACFLT) Bernard A. Clarey’s (USNA ’34) USS PINTADO (SS-387) at 1645 (H-time) receives an "Ultra" signal from ComSubPac's codebreakers alerting him that a Japanese carrier, "a battleship or cruiser" and three destroyers are heading S through the Formosa Strait. Clarey's wolfpack of PINTADO, JALLAO (SS-368) and ATULE (SS-403) with LtCdr John P. Roach's (USNA ’32) pack of HADDOCK (SS-231), HALIBUT (SS-232) and TUNA (SS-203) form a picket line to intercept the carrier group.
At 2020 (H-time, 2120 JST), Clarey picks up the carrier flanked by two destroyers with another destroyer ahead and a light cruiser astern. Clarey notes the carrier has a small island forward of amidships. He sets up and fires all six of his bow torpedoes at the carrier's port side; but torpedoes are deliberately intercepted at 2250 by LtCdr Yamazaki Nitaro's escorting destroyer AKIKAZE, which breaks up, upends, and sinks in eight minutes with all hands, 205 officers and men. The other ships are not hit and escape to the West.[Note 2]
6 November 1944:
Evening: arrives at Brunei with shells and supplies for Kurita’s fleet.
8 November 1944:
At 0400, departs Brunei towards Pratas Islands (near the Formosa Strait) with 1st Diversion Attack Force consisting of BatDiv 1's YAMATO and NAGATO, BatDiv 3 KONGO and HARUNA, heavy cruisers HAGURO and ASHIGARA, light cruiser YAHAGI and DesDiv 17's HAMAKAZE, URAKAZE, ISOKAZE, and YUKIKAZE; ASHIGARA, delayed by refueling, is detached and returns to Brunei. Subsequently splits off and heads for Manila with the damaged TONE, KISO, YUZUKI, UZUKI, and SHIGURE. The remainder of the task group makes a feint through the Balabac Strait, then returns to Brunei.
9 November 1944:
At 1900, arrives at Manila. Unloads troops and supplies.
11 November 1944:
At 1100, departs Manila for Kure, with the damaged TONE in company; both ships are escorted by DesRon 2’s SHIGURE, DesDiv 30’s YUZUKI and UZUKI. KISO remains behind.
13 November 1944:
Attacked south of Mako at 0640 (I-time/JST) by LtCdr (later Rear Admiral-Ret) Joseph B. Icenhower’s (USNA ’36) USS JALLAO (SS-368). JALLAO narrowly avoids being rammed by JUNYO when carrier makes a sudden turn and passes within 200 yards. Icenhower fires six stern tubes at carrier's starboard at 1,400 yards as shears away, but no damage is sustained. (JUNYO had apparently been sighted and with TONE misidentified on 12 Nov and excitedly reported as battleship YAMATO headed north!) Arrives safely at Mako that afternoon.
14 November 1944:
Departs Mako for Kure.
15 November 1944:
En-route to Kure; at 2249 ( Item/JST -time) detected by Cdr (later Rear Admiral-Ret) Eugene B. Fluckey’s (USNA ’35) USS BARB (SS-220). Fluckey mis-identifies carrier as Shokaku-class, believed to be new carrier KATSURAGI. Fires five bow tubes at target’s starboard side, and claims one hit on stern at 2327, but in fact, no damage is sustained.
Assigned this day to Combined Fleet, CarDiv 1 also consisting of light carrier RYUHO.
23 November 1944:
Departs Kure for Sasebo with DesDiv 41’s FUYUZUKI and SUZUTSUKI.

30 November 1944:
At 0725 (H-time, 0825 JST), sighted by LtCdr Frank E. Haylor’s (USNA ’36) USS HAKE (SS-256) outside Manila Bay, but the submarine is too far away to intercept. At 1520, arrives at Manila.
1 December 1944:
At 0500, departs Manila for Mako with DesDiv 41’s FUYUZUKI and SUZUTSUKI and MAKI.
3 December 1944:

5 December 1944:
At 1040, joined at Mako by battleship HARUNA, DesDiv 18’s KASUMI and DesDiv 21’s HATSUSHIMO.
6 December 1944:
At 0040, carrying 200 survivors of the super-battleship MUSASHI, departs Mako with HARUNA, escorted by DesDiv 41’s SUZUTSUKI, FUYUTSUKI, and DesDiv 43’s MAKI. (KASUMI and HATSUSHIMO do not continue with them, but at 1000, head back south).
8 - 9 December 1944:
Between midnight and 0330 the task force is attacked by submarine wolf-pack consisting of Cdr (later Captain-Ret) Ralph E. Styles’ (USNA ’33) USS SEA DEVIL (SS-400), Cdr Clyde B. Stevens’ (USNA ’30) PLAICE (SS-390), and Cdr (later Rear Admiral-Ret) Louis D. McGregor’s (USNA ’30) REDFISH (SS-395). Exactly who hit what and when is not entirely clear, but JUNYO receives two torpedo hits, and destroyer MAKI one. One hit the carrier's starboard engine room, while a second torpedo nips the stem, the explosion breaching the bow plates. About 5,000 tons of water enter the carrier, increasing draught to 10 meters and for a time give her a 18 degree list to starboard, while four petty officers and fifteen men are killed. However, the avgas tanks were empty at the time and there is no fire. Fortunately for the carrier the centerline bulkhead dividing the engine rooms holds despite the starboard engine room being filled. By going ahead on the port engine while applying the rudder somewhat to the left, JUNYO manages to make 13 knots and holds a straight course. At half-speed the carrier manages to escape further attack by entering shoal waters where submarines could not follow. Escorting destroyer MAKI intercepts one of the "fish" and has a smashed bow with four sailors killed, but limps to Nagasaki. [Note 3]
10 December 1944:
At 1100, arrives at Sasebo with HARUNA, still listing considerably to starboard. Captain Shibuya moors her without assistance.
18 December 1944:
19 December 1944:
Captain Shibuya is relieved; Sasebo Naval Yard takes over.
1 January 1945:
Reassigned to Cardiv 1, 2nd Fleet.
20 January 1945:
Attacked by land-based bombers while in drydock; claims to have shot down one enemy plane.
28 January 1945:
Further repair and upgrades are abandoned due to lack of materials. Though temporary repairs were completed, these did not include the starboard engine room.
1 April 1945:
Moved from Sasebo docks and anchored in nearby Ebisu Wan (Bay).
20 April 1945:
Cardiv 1 is dissolved.
23 April 1945:
Still at Ebisu Wan (Bay), near Sasebo. Camouflaging begins.
24 April 1945:
Classified as ship of 4th Reserve Fleet.
In Ebisu Wan (Bay), Sasebo. Moored with incomplete carriers KASAGI and IBUKI. Crew is under training, and engaged in camouflage and upkeep.
12 May 1945:
Captain Maehara Tomiyoshi (44) is assigned as commanding officer.
1 June 1945:
Relocated again from Sasebo Navy Yard and anchored in Ebisu Wan (Bay) nearby. Heavy camouflaging continues. Also anchored there are the incomplete carriers KASAGI and IBUKI.
20 June 1945:
Classified as guard ship.
5 August 1945:
Captain Maehara is ordered to strip carrier of all armament and other equipment for defense use elsewhere.
2 September 1945:
Japan surrenders, and the three carriers at Ebisu Wan (Bay), Sasebo area are turned over to the Allies.
8 October 1945:
Boarded by American Naval Technical officers. After inspecting the ship, they declare that repairs to restore the vessel to service even temporarily for repatriation duty would be a waste of resources. Delegated for scrapping.
30 November 1945:
Removed from Navy List.
1 June 1946:
Dismantling begins at Sasebo, completed by 1 August 1947.
Note 1: Recently, there has been some question whether some of the carriers, JUNYO included, received the rocket mount upgrade before the Battle of Marianas. The main clue seems to hinge on what changes prompted the inclination testing on 3 May, 1944, among other hints. However, this remains unresolved at this date and the conventional time of installation has been retained.
Note 2: The Japanese held Lt.Cdr. Yamazaki and his crew’s deed in high regard. The crew of the Junyo erected a monument to pay tribute to Akikaze’s sacrifice in the Kure Naval Cemetery.
Note 3: There is some question about which submarines scored in the 9 December attacks. No less than three U.S. submarines, the USS Sea Devil (SS-400), USS Plaice (SS-390), and USS Redfish (SS-395) attacked the task force. In an attempt to resolve the matter, the patrol reports were examined and compared to IJN records. There is reason to believe the usual credits are in need of adjustment. At the moment, the only attack that can clearly be matched is USS Redfish's final attack with ten torpedoes at extreme range at 0324. Captain Shibuya reported a brace of these passed down both sides of the carrier, but none hit.
Though mostly repaired (except for starboard engine) and manned after the torpedo attacks of December 1944, vessel could never be operated due to lack of aircraft and fuel.
