Title: This Week - The Hunt for Yamamoto

THE HUNT FOR YAMAMOTO

The Mission
(http://i906.photobucket.com/albums/ac270/puma44/Routes_to_engagement.jpg)

Major Mitchell, the CO of the 339th Fighter Squadron, based at Guadalcanal, headed over to the bunker with Tom Lanphier, one of his top pilots, where they met Admiral Marc Mitscher and "every brass hat on the island." It was April 17, 1943.


 The senior Navy and Marine Corps officers took over the discussion, and Mitchell and Lanphier were gradually pushed out to the edge of the group. When the planning bogged down, they were re-invited. All agreed that only U.S. Army Air Force P-38 Lightnings, equipped with drop tanks had the range for the job. Mitchell ruled out any attempt to get Yamamoto during a shipboard leg of his trip, "My men wouldn't know a sub-chaser from a sub. It'll have to be in the air." After more discussion, Admiral Mitscher cut it off, noting that Mitchell and Lanphier would have to work out the details. Extra-large drop tanks had already been ordered; Mitchell wanted a top-quality Navy compass. He explained the risks and uncertainties: missing Yamamoto altogether, new drop tanks being installed that night, running out of fuel, getting jumped by Zeros. They guessed that he would be flying at about 5,000 feet. After the wave top flight, the Lightnings of the killer group would climb to that altitude; the cover group to 20,000. Mitchell emphasized the importance of low level flying and radio silence; he didn't want the Japs to pick up on this mission.
 
At takeoff, on April 18th,  McLanahan blew a tire and shortly afterwards Moore's new tanks wouldn't feed. These two 'shooters' dropped out of the mission; Hine and Holmes replaced them.  Mitchell's remaining 16 planes thundered along at wave top level to avoid Japanese spotters. They sped northwest, sweeping widely away from Jap-occupied New Georgia. Mitchell tried to hold the planes at the dangerously low level of thirty feet; with only the smooth ocean below, depth perception was almost nonexistent. Horrified, Mitchell watched helplessly as one plane dipped low enough to kick up spray onto his windows. But the pilot kept control and eased the big fighter back up out of the waves. By 0800, the American raiders were 285 miles from the planned interception; at that minute, Admiral Yamamoto's Betty bomber took off from Rabaul, precisely on time for his scheduled 1000 arrival on Bougainville. His entourage included one other Betty bomber and six Zeros. Yamamoto's chief of staff, Admiral Ugaki, flew in the second bomber.

At 0900, Mitchell made their last change, heading northeast, directly toward the coast of Bougainville, only 40 miles away. He also began the slow climb for altitude at this point. The pilots test fired their guns. The minutes ticked away and the Lightnings droned on, climbing as the mountains of Bougainville came into view. 0934 when sharp-eyed Doug Canning called out "Bogeys, eleven o'clock. High." Mitchell couldn't believe it; there they were, right on schedule, exactly as planned. The Japanese planes appeared bright and new-looking to the pilots of the 339th. They jettisoned their drop tanks and bored in for the attack. Holmes and Hine had trouble with their tanks, only Barber and Lanphier of the killer group went after the Japanese bombers.


All the other P-38s followed their instructions to fly cover. The attack itself has been shrouded in uncertainty and, unfortunately, in controversy. Both Lanphier and Barber claimed one bomber shot down over the jungles of Bougainville. Frank Holmes claimed another shot down over the water a few minutes later. From Japanese records and survivors, among them Admiral Ugaki, the following facts are certain. Only two Betty bombers were involved; Yamamoto's was shot down over Bougainville with no survivors; the second went into the ocean and Ugaki lived to tell about it. Shortly after the attack, a Japanese search party located the wreckage, including the Admiral's body, which they ceremonially cremated.

The pilots uneventfully flew back to Guadalcanal, where upon landing; the ground personnel greeted them gleefully, like a winning football team.

Allied (Knights)
Objective: Determine Yamamoto’s intended route to A26, intercept, and eliminate all intercepted aircraft. 
P-38G
F4F
F4U
C-47 (Supplies only)
M4A3
Jeep

Axis (Bishops)
Objective:  Safely transport Admiral Yamamoto from A19 to A26 safely for inspection tour.  Return to the Admiral to A19 at his discretion.  Theatre fighter units provide air escort and combat air patrol for the Admiral’s departure, transit and return to his field headquarters.
G4M1 Betty
A6M5
A6M2
C-47 (Supplies only)
M4A3
Jeep

Burn rate 1.0
Enemy icons off
Radar altitude 100’
Ack hardness .25
Kill shooter off

For more efficient game play, Yamamoto’s route on the map will be from A19 to A26 vs. the historical route actually flown.
Fuels supplies are short for both sides in the theatre and thus drop tanks are not available for all aircraft at all bases.  Weather is forecast to be mostly clear and unlimited visibility with reduced visibility in the late afternoon hours due to monsoon rain showers.
For achievement of Allied and Axis objectives, announce on “ALL” text buffer when accomplished.  Good hunting!

Many AH people will claim that such a DAR setting would be the end of AH.

Most excellent write-up, Puma, should be exciting.  But...Corsairs...?

Thanks Oldman!   In my research, there was some discussion about how the Corsairs didn't have the range for the expected trip.  So, the P-38s were tasked.  Since they appear to have been in theatre at the time, they are included in the setup.

Hi guys <S>
  Puma, nice job on the OPORDS, looks sweet and should play out
nicely.
   This is the setup which will be put into place on Friday, the 25th correct?
I've started up a poll in The 47 Ronin squadron forum area gauging
interest in having a second "Squad Night" during the week during
which we will fly in the "Axis vs Allies Arena".
  Thus far, 7 guys have responded, and all were "yes" votes.
While that seems a low number given we've got 25 guys in
the squad, that's actually a good number of responses as
only half of the Ronin know how to read or write.  :D
    As you folks have "Staff Night" on Tuesday evenings, which
guarantees at least a few guys will be in there on that night,
I'm going to present that to my Command Staff for their approval.
   
Best regards,
Oddball

Isn't this time frame too early for the A6M5 and late for 6M2? Wouldn't the A6M3 have been the primary zeke in service at this time?

Kill shooter is off?

Thanks for the input, Trap.  I used the in service list to pick the Zeroes.  If you've got a more accurate source, I'd be glad to reconsider.  :salute

Hi guys,
   The 47 Ronin will be holding an unofficial "Squad Night" in there each
Tuesday at 9PM. This date and time was chosen as that is the night
the arena staff fly in there, so guarantees there'll be a few guys in
there besides us. ;)
  I can't guarantee numbers, but would guess that we'd be fielding
7-12 guys in there each Tuesday night for an hour or two depending
on the dynamics of the arena itself.
  This week we'll be escorting Yamamoto from Rabaul to Bougainville
per the excellent write-up by Puma.
  I'll be lifting a formation of G4Ms, only one of which will be "carrying"
Yamamoto. Prior to take-off, I'll advise my guys which of the three
he is aboard. If the Americans shoot down -that- G4M, they win.
I'll announce on "All" or "200" channel if/when Yamamoto is "killed".
  One thing I do suggest is that the killshooter be turned "ON" as
having it off puts us at the mercy of "gamekillers".
  Anwyay, I've posted up our intent in both the "General Discussion"
and "Squadrons" area of the BBS in order to try and generate some
interest in it.
  See you guys Tuesday night. <S>

Best regards, Odd

Hey Puma, this is what I've got:

A6M2 in service 09/40
A6M3 in service 06/42
A6M5 in service 10/43 for the "a" model and 12/44 for the "c". Our "b" is somewhere in between these dates.

Thanks, Trap!  The Yamamoto shoot down occurred April 18, 1943.  So, looks like the "5" wasn't quite around yet.  I'm out of town for the week and Jaeger is loading on Thursday night for me.  I'll ask him to change it to the "2" and "3".  Consider the "2"  a hangar queen.  If you can get it running, fly it.   :salute

 they were there. if i recall from reading, even they were stretched to near their limits on the range. i think one of the accounts i read mentioned that it was pure luck that they spotted his flight......and of course the rest is history.


 very nice.

Cap, here's some interesting stuff I found researching the P-38's long range cruise:

Until Lindbergh convinced the guys in the 5th AF to do otherwise, the P-38 was flown at low (about 16-18") MAP/autorich/2600RPM. This not only caused excessive fuel consumption, but also fouled plugs. Another problem it created was that it dropped cylinder head and oil temperatures well below proper operating levels. This caused the engines to run rough and hesitate when the throttles were advanced upon entering combat. It also caused the turbos to overspeed because the oil was congealed in the turbo regulators. This was yet another area where the USAAC and Lockheed dropped the ball.

Lindbergh told the guys in the squad he was flying with to try flying at 36"MAP/autolean/1600RPM. The mechanics went nuts, swearing the Allisons would be junk in one flight. However, Mac MacDonald, the CO, set about testing the idea out. After a few flights, they found fuel consumption was dramatically reduced, and that the engines actually ran smoother and responded much better to the throttles. The mechanics removed the engines from the plane and found they were in excellent shape, better than the engines in any other plane.

Here's narrative found in another article:

The second and critical passage made by the group concerned fuel consumption. With additional fuel cells in the J model P-38, Satan's Angels had been making six and one-half and seven-hour flights. On I July Lindbergh flew a third mission with the group, an armed reconnaissance to enemy strips at Nabire, Sagan One and Two, Otawiri, and Ransiki, all on the western shore of Geelvink Bay. Already Lindbergh's technical eye noticed something. After six and one-half hours flying time, he landed with 210 gallons of fuel remaining in his Lightning's tanks.

Two missions later, on 3 July, the group covered sixteen heavies on a strike against Jefman Island. Lindbergh led Hades Squadron's White Flight as they wove back and forth above the lumbering B-25s. After the attack the Lightnings went barge hunting.

First one, then two pilots reported dwindling fuel and broke off for home. MacDonald ordered the squadron back but because Lindbergh had nursed his fuel, he asked for and received permission to continue the hunt with his wingman. After a few more strafing runs, Lindbergh noticed the other Lightning circling overhead. Nervously the pilot told Lindbergh that he had only 175 gallons of fuel left. The civilian told him to reduce engine rpms, lean out his fuel mixture, and throttle back. When they landed, the 431st driver had seventy gallons left, Lindbergh had 260. They had started the mission with equal amounts of gas.

Lindbergh talked with MacDonald. The colonel then asked the group's pilots to assemble at the recreation hall that evening. The hall was that in name only, packed dirt floors staring up at a palm thatched roof, one ping pong table and some decks of cards completing the decor. Under the glare of unshaded bulbs, MacDonald got down to business. "Mr. Lindbergh" wanted to explain how to gain more range from the P-38s. In a pleasant manner Lindbergh explained cruise control techniques he had worked out for the Lightnings: reduce the standard 2,200 rpm to 1,600, set fuel mixtures to "auto-lean," and slightly increase manifold pressures. This, Lindbergh predicted, would stretch the Lightning's radius by 400 hundred miles, a nine-hour flight. When he concluded his talk half an hour later, the room was silent.

The men mulled over several thoughts in the wake of their guest's presentation. The notion of a nine-hour flight literally did not sit well with them, "bum-busters" thought some. Seven hours in a cramped Lightning cockpit, sitting on a parachute, an emergency raft, and an oar was bad, nine hours was inconceivable. They were right. Later, on 14 October 1944, a 432nd pilot celebrated his twenty-fourth birthday with an eight-hour escort to Balikpapan, Borneo. On touching down, he was so cramped his crew chief had to climb up and help him get out of the cockpit.

Not sure.  The scenario takes place in April 43.

The first 1A's started operations and the end of October 1943. It would be January of '44 before they saw combat in large numbers.

Had a most excellent fight with a 38G against Knife's M3 tonite.  I lost, of course, but it really was a most excellent fight.  Rayace ran Yamamoto's route - there's an issue with A14 belonging to the wrong side, I believe he said.  Perhaps it can be checked out?

OK guys, here's the deal. puma's writeup is based on the old slot terrain. its a huge terrain that's 512X512. this week we released the AVA slot. its 128X128. in order to make it smaller, we had to change some of the bases and eliminate a lot of the land terrain. basically, we took only the lower portion of bougainville to Guadalcanal.

therefore the base numbers have changed. since we don't have a northern base to run from yamamoto is taking off from base 17 and landing at base 23. the allies are taking off from base 14 and trying to intercept him. sorry for the confusion. i hope this straightens it out for everyone. sorry for the confusion.

Clarification relayed to Yamamoto, flight will resume flight at around 9:00 PM EST
