How would history have changed if HMSIndomitable had successfully joined Force Z?

I agree to a certain extent. From what I've heard, the Royal Air Force had some room to send some fighters to the British Malaya at the time, but if you don't, you can't say that you're not responsible for it.
There is another thread going on by Fatboy Coxy called Malaya What If. It goes into many of the issues leading to the fall of Singapore. I don't agree with him that these fundamental problems could be fixed before the war, but his story is well written, and logical. He hasn't gotten up to the sending of Force Z in his timeline yet, so I don't know how he'll deal with that. Take a look at it, you might enjoy it. Take care.

I'll take a look when I have time. Thank you.

By the way, is there a British Pacific Fleet thread?

Grenfell's "Main Fleet to Singapore" brings up the point that the Japanese air force was rated equal in quality to that of Italy by the RAF, the RAF rated themselves 60% better than the Japanese and Italians. It was pointed out to me a while back than a purely neutral, objective observer could look at the record of the Japanese over the previous couple of years and come to the logical conclusion that they couldn't be all that hot in general military terms because they had been hacked about badly at Khalkin Gol by the same Russian forces that had been slaughtered in far bigger numbers by the Germans. While the Japanese fighters did well at Khalkin Gol, Christopher Shores notes that their bombers lost quite badly against Chinese fighters.
Except it was the Army that got their noses bloodied at Khalkin Gol and not the Navy.

As late as 1943, many Allied personnel were still of the mistaken opinion that the JAAF and JNAF used the same types of aircraft, including the A6M - there were even some who did not realise that Japan had no independent air force.

However, the RN had a reasonably high opinion of the Italian pilots in many ways, and officially operated on the basis that the Japanese were as good as they were in surface ships, although the Brits also thought they themselves would actually be better. Perhaps where the RN was misled was that the Italian level bombers dropped bombs in very impressively tight groups - but almost always missed just like every other air force that tried to hit ships from up on high. That would appear to have given Phillips a fair indication that the long range bombers he may face wouldn't be an impossible foe.
I bet you even the Germans and Italians would have laughed if they had been told in 1941 that Japan possessed bombers with combat radiuses of 1500 km.

First of all on Tom Phillips suitability as a Force Z Commander. He was a s good of a choice as any given his assigned mission. He was not an ignorant battleship admiral. His step-son Gerald served in HMS Jackal off Crete and gave his father first-hand accounts of the sinking of British ships by air attack. Phillips asked for air cover and was denied it. In April 1941 Phillips in his position at the Admiralty advocated for Hurricanes to be sent to Malaya instead of Buffalos. '

As far as the blame game goes, I don't blame Phillips as much as Palliser and Pulford; or the three of them plus Percival as much as Churchill and Whitehall in general, nor the Government of the day as much as two decades of poor defence policy from 1919-1939.

Having said that, I do not blame the British anywhere near as much as I do CREDIT the Japanese for having run a brilliant, imaginative campaign that was as reckless as say the German invasion of Norway. Japanese planning was incredibly risky, and subject to quite capricious weather and sea conditions. Any clear reading of the campaign, and especially Force Z cannot help but emphasize the extreme streaks of luck the Japanese enjoyed at key times.

The question is - and I believe this to be the rationale for a Re-Do - what impact would the addition of HMS Indomitable and escorts have on the OTL examples of luck the IJN had in the destruction of Force Z?

While the Japanese fighters did well at Khalkin Gol, Christopher Shores notes that their bombers lost quite badly against Chinese fighters.

Oddly enough, Grenfell says that the Chief of Air Staff said the Japanese could attack Malaya with 700+ plans and the RAF needed 336 modern aircraft to defend against them. That not only shows a pretty dismissive attitude, but it seems to be well below the 60% ratio.

However, the RN had a reasonably high opinion of the Italian pilots in many ways, and officially operated on the basis that the Japanese were as good as they were in surface ships, although the Brits also thought they themselves would actually be better. Perhaps where the RN was misled was that the Italian level bombers dropped bombs in very impressively tight groups - but almost always missed just like every other air force that tried to hit ships from up on high.

The 336 estimate probably assumes neutral Thailand and a long round trip for the Japanese and a defensive fighter heavy force.

If 700 planes were attacking they are probably assuming 300 fighters and 400 bombers which gives 300 British fighters a heavy advantage (if you assume the 60% rule).

Also the Japanese attack might be broken into multiple waves giving the British the ability to concentrate.

My point is that they can assume that they are 60% better and that defense gives them a big advantage. They can be wrong though. Even if they believe they are better it relies on quality of plane. The RAF can be 60% better but if Malaya comes last and gets Hurricane Is its a lot differenct than mkv spitfires.

We also have to remember that French Indo China was not fully occupied until the 28 July 1941 - suddenly putting Japanese airpower within striking distance of Singapore, and the IJN with basing much closer to the Malay Peninsular and giving the British about 4 months to scramble to position more forces there at a time when they were rather busy elsewhere!
 
The point is that it's not a "blunder" if it's caused by the first use of a weapon no one knows about, or by being placed in an impossible situation. Only alien space bats know about every possible weapon or can win all the time.

The fact "isn't" that people, even high commanders, are ultimately responsible for things they cannot alter or avoid. They're not.

There are many British commanders I don't defend; I haven't defended Perceval and I don't think I'd defend Blamey or others. There's also commanders from other nations I do defend. I have actually, in my work in government enquiries, investigated a real life current admiral and an AVM (I tried to get higher-ups to take action but was overruled, sadly) so the reality is that I take real-life steps against people in high places in the military, rather than just criticising dead admirals with hindsight. But that doesn't mean we just ignore the reality of the situation that Phillips was placed in.

But if we just say "Oh, Phillips was an idiot" we lose a great chance to understand why he did what he did, and that's where we learn a lot. We learn very little from saying "X was a moron"; all we get is the ego boost of "proving" we know more than someone else, while conveniently ignoring the fact that we don't have to deal the cards they were dealt with.

It's all too easy for people to criticise people for taking a particular action in a particular situation, and then to ignore what would happen if that approach was followed elsewhere in similar situations. I notice you don't seem to have said what approach you think Phillips should have taken, and why - and you haven't applied a similar approach to similar facts elsewhere.

It seems that you are critical of Phillips' decision to take Force Z into an area where he could have been attacked by about 40 twin engined bombers. Okay, let's then apply that approach to Crete, Greece, Malta Convoys, and other situations....... the result is probably disaster of the highest order.
Did I say Philips was an idiot?
 
With that said, my comment was not needed, snarky, pointless, and did nothing to add to the overall discussion. So I am sorry for that.
I had yet to see a sympathetic contextual description of the situations other commanders.

The Japanese did a lot to make their own luck.
 
Less than a week after arriving, Force Z had failed in its mission of deterring a Japanese attack on Malaya. The decision to sortie was largely a result of a bombing raid on Singapore that would not go spectacularly well for the IJNAF 22nd Air Flotilla. The IJNAF actually hoped to catch Force Z in port with an air raid scheduled to coincide with the bombing of Pearl Harbor. The raid was risky, nearly 1400 miles round trip, with attendant navigational difficulties. The northeast monsoon conspired against the 22nd Air Flotilla, just over half the planned number, 54 Mitsubishi G3M Nell bombers got airborne, and only 17 from the Mihoro Air Corps reached Singapore due to miserable flying weather. One plane from Genzan Air Corps was lost due to mechanical failure.

The bombs dropped were ineffective, although in the city center not yet blacked out by wartime restrictions, and 200 (mostly Chinese) civilians were killed. The only military targets hit were Tengah and Kallang Airfields, but no aircraft were destroyed and there were few casualties. Anti-aircraft (AA) gunners failed to hit any planes. The raid was a significant factor in Phillip’s decision to sortie, he considered his force safer at sea than in port. That assumption then fed the decision to use Force Z in an attempt to destroy Japanese landing forces.

OTL events of 9 December (some times which are marked @ are good faith estimates as the historical record is unclear):

@0930 – IJNAF G3M2 (Nell) recce plane reports via radio Force Z is still in port. The observer mistook the floating drydock for a capital ship. RA Matsunaga Sadaichi, commander of 22nd IJNAF Air Flotilla orders his aircraft armed with bombs for an attack, but weather does not clear in time for a launch.
@1300 – VA Ozawa Jisaburo is informed landings are complete, and directs transports and escorts to sail to various ports to commence next scheduled operation, primarily invasions of both east and west coasts of Borneo. The dispersal of warships will make reconsolidation into battle formation difficult.
1343 – HMIJS I-65 spots Force Z. She is travelling on the surface, and has elevated her periscope for additional visibility. Force Z is zigzagging at 18 Kts. Her sighting report is garbled and difficult to decode. She continues to track Force Z.
1540 – Sighting report from HMIJS I-65 is finally forwarded to both RA Matsunaga and VA Ozawa by HMIJS Kinu flagship of SubRon 4. The report is initially disbelieved. A photo recce G3M2 still in flight is ordered to land at Saigon rather than Te Duam Airfield to allow more rapid analysis of the photos of Singapore Naval Base. CruRon 7 (HMIJS Kumano, Suzuya, Mikuma, Mogami) are ordered to launch E13A (Jake) long-range scout seaplanes.
@1545-1615 – HMIJS Kinu launches E7K (Alf) seaplane to follow up sighting by HMIJS I-65.
1550 – HMIJS I-65 loses contact.
1652 – HMIJS I-65 regains contact.
@1700 – Photos reveal Force Z has left Singapore. RA Matsunaga orders a partial rearming of planned strike rearmed with torpedoes. Launch authorized as squadrons are ready.
1700 – E7K from HMIJS Kinu locates HMIJS I-65; then Force Z.
1705 – HMIJS I-65 crash-dives after spotting E7K.
@1710 – E7K vectors in E-13A (one each) from HMIJS Kumano, Suzuya. Phillips knows Force Z has been found.
1809 – Sunset.
@2000 – G3M2 recce plane begins dropping flares over VA Ozawa’s flagship HMIJS Chokai and destroyer HMIJS Sagiri. Attack is averted at last minute, and air operations are cancelled until dawn 10 December 1941.
Flares are reported by HMS Electra. Phillips continues with a preplanned course change.
2258 – Monsoon conditions clear enough for normal visibility of moonrise.
2352 – HMIJS I-58 unsuccessfully launches five torpedoes at HMS Repulse. The attack is not noted by Force Z.

Any questions/comments regarding the OTL sequence of events for 9 December 1941?
 
Concur completely, hence why I credit more than I blame. But the question remains, can HMS Indomitable undo some of that luck?
From what was posted, a submarine was the one that spotted Force Z. With a carrier, especially one with ASW aircraft onboard, the sub is either sunk or submerged. Force Z might get away. The IJN does not know where Force Z is. How many planes can they spare to search? They CAP should be able to take care of any search aircraft. It could disrupt some of the IJN plans.

Quite agree. See more.

The small air group on Indomitable will hardly form an impenetrable ASW zone. You're only talking about sighting a periscope. When I 58 fired torpedoes it was dark giving no chance to see the periscope. The Japanese have lots of aircraft for scouting out Force Z. You can't assume all the scout planes would be shootdown. The Sea Hurrican wasn't much faster than some of the Japanese scout planes.
 
It's also worth considering that the Fall of Singapore was a much more contested affair than people realise, if Perceval had actually seized the initiative and counter-attacked while the Japanese had begun to outstrip their supply lines. I'm not sure it would have bought them much more time, but it might have given Yamashita a nasty surprise.

In that sense, a modestly successful Force Z might cause a butterfly to take flight .... also gives ABDACOM much sharper teeth than OTL - even if it's performance was hindered by communication and coordination issues.

It's worth remembering that OTL some land based British aircraft arrived in time to witness the sinkings. If Indomitable's air wing can delay the attackers, the buffaloes have a chance to arrive while the Japanese aircraft are still around. They won't know how many more are on their way, nor be sure if they are land or carruer based. That mucks up attack runs even more and likely tells them it's time to go home happy they've badly damaged three big British ships.
So the chances of saving any unsunk ships and especially of rescuing crew goes up substantially, so it's quite likely to be better than OTL.
 
HMS Indomitable is limited by the number of aircraft she can accommodate. As of 8 December 1941, she was assigned nine Sea Hurricane of No 808 Sqn; ten Fulmar (11 crews) of No 800 Sqn (two were lost en-route to the West Indies, one crew rescued – I assume the same en-route to South Africa); 12 Albacore each from No 827 and 831 Sqn. This is a total 43 aircraft, her capacity was rated at 48. ASW patrols are conducted by Walrus aircraft, six total of which are embarked in HMS Prince of Wales, Repulse and Kenya. Two are launched by catapult, and land aboard HMS Indomitable. They cannot be launched by catapult. (Note: Among the carriers that operated the Walrus were HMS Ark Royal and Victorious.) Recce duties are done in three shifts, the first and second with five Fulmar, third with six Albacore.

ATL events of 9 December:
@0930 – Same.
@1300 – Same.
@1330 – Walrus spots HMIJS I-65 and likely sinks her. RN ASW crews are trained against U-boats with a dive time of 17-25 seconds. HMIJS I-65 takes 56-59 seconds. In addition, the E7K (Alf) seaplane from HMIJS Kinu is not noticed by the submarine’s lookouts for about five minutes. I doubt they would notice a Walrus. Even if not sunk she is probably damaged. Even if undamaged, she will not see or report Force Z.
@1530 – Recce spots HMIJS Kinu. Unless someone on the flag bridge remembers that up until the 1937 edition, “Jane’s Fighting Ships” published the disposition of the IJN, and that light cruisers were flagships of submarine squadrons, Phillips will wait until @1610 to allow a torpedo strike by Albacores. This will allow the strike to land before sunset, and he would be sure no possibility of hitting another target would exist.
@1700-1715 – HMIJS Kinu sunk by torpedo attack. Her report of attack by carrier-borne aircraft comes as a surprise by RA Matsunaga and VA Ozawa. RA Matsunaga orders aircraft rearmed. IJN submarine picket line is moved further east.
1809 – Sunset.
@2000 – G3M2 recce plane begins dropping flares over VA Ozawa’s flagship HMIJS Chokai and destroyer HMIJS Sagiri. Attack is averted at last minute, and air operations are cancelled until dawn 10 December 1941.
Flares are reported by HMS Electra and radar aboard HMS Kenya, HMNLS Jacob van Heemskerk, and once the destroyer has maneuvered to bring her Type 286M to bear, HMS Bedouin.
@2025-2100 – Using tactics exercised prewar, and used very effectively at Cape Matapan; destroyers HMS Intrepid and Electra to lose within searchlight range, while HMS Prince of Wales, Repulse and Kenya close to @6,000 yards before HMIJS Chokai and Sagiri are lit up and firing commences. Neither ship is able to either escape or launch torpedoes. HMS Prince of Wales suffers breakdowns in both her quadruple turrets. As with HMIJS Kinu, full contact report is made but IJN confusion over whether to countermand VA Ozawa’s orders postponing air operations until the next day results in no actions being taken. HMS Indomitable, Tenedos and HMAS Vampire are ordered 20 miles to the south for the duration of the battle
2258 – Same.
2352 – Same.
2359 - Force Z has set curse and speed to a point100 miles east of Kota Bharu at sunrise - @0400.

Note: Slight edit on last line
Second edit after comments - 100, not 10 miles east of Kota Bharu. Egregious error on my part. Thought I fixed it. Ooops !!

Nice to see some positivity
 
I am certain that Phillips knew he was not coming back but expected to give it his best effort. The day and time to actually be near Thailand is actually the night of the 8th. That way they can stop the initital landings etc. A carrier even one with honestly poor aircraft increases your defensive and offensive capabilities in ways that are hard to imagine.

The Japanese torpedo's are highly effective but not without problems. In the right circumstances they are devastating but at the time of this happening the torpedo crews used some very bad procedures some of which caused premature detonations and other issues.

I can't see Force Z getting out of this without losses, I can see crippled Capital ships needing yard time but with a few scalps.
