American side of Rabaul Mission January
Research by Justin Taylan
5, 1943 Mission 4L: six B-17s and six B-24s took off from 7-Mile
Drome near Port Moresby to bomb Rabaul, shipping Simpson Harbor and the airfield at Rabaul. The American formations arrived over Rabaul in
three groups, at different local times:
2 B-17s bomb Vunakanau dispersal area, and are intercepted
by by 12-15 ZEKES.
They claim 7.
6 B-24s attach ships in Rabaul's Harbor, they are intercepted by
12-15 fighters mostly ZEKES but possible "Me 109s" (Mis-identified
Ki-43 Oscars). They claim 2.
6 B-17s. Rabaul ships. Intercepted by 8-10 ZEKES and possible HAPS.
[ General Walker's B-17F "San Antonio Rose" 41-24458 was part of this last group. ]
Two B-17s were lost, B-17F
41-24538 and B-17F "San
Antonio Rose" 41-24458 with Brigadier General Kenneth Walker,
Commanding General V Bomber Command aboard.
Misidentifcation of Me-109
Both old and new type Zero
noted as well as E/A resembling ME109. Enemy aircraft made determined
attacks mostly from the front quarter". The 'ME-109s' were likely
Ki-43 of the 11th Sentai which had just arrived from Truk to Rabaul.
In the South Pacific, there were many reports of 'Me-109s', often when pilots
confused the Ki-61 Tony for that aircraft. In this case, the aircraft
were not Ki-61s as the first unit with this type (68th Sentai) did not arrive
at Rabaul until April 1943, three months later.
Japanese side of Rabaul Mission January
Research by Richard Dunn
Both the Japanese Navy
(Zeros) and Army (Oscars) intercepted this raid. The army and navy shared
Rabaul air defence. The navy took the early shift and intercepted the
first raid. The army apparently took the later shift and took on the
B-17/B-24 formation. The evidence points to the fact that Walker's
B-17 was shot down by a Ki-43-I Oscar. The fact that there was some recognition
descrepencies in the raid may be additional evidence that Ki-43 Oscars
(less familiar aircraft) were involved, and mistaken as HAPS or Me-109s.
Japanese Navy Interception
Japanese Mono. # 121 (Navy)
says 3 B-17s raided Rabaul. 12 fighters intercepted (A6M Zeros of the 582nd Kōkūtai). They claim 1 B-17 shot down. [ the 0925 raid]
Japanese Army Air Force Interception
Japanese Mono. # 37 (Army) says two air attacks by about 5 B-17s and B-24s
(5 each?). Part of the 11th Sentai (Ki-43-I Oscars) intercepted and claimed
4 (including 3 doubtful). A
translated Japanese Army Intelligence is more specific
about claims saying 2 B-17s (1 probable) and 2 Consolidated (probables) were
shot down. Three Japanese aircraft were lost but all pilots were saved. The
second B-17 limped close to Goodenough before ditching (403 BS). [this
suggests that B-17F
41-24538 was claimed as the probable and Walker's B-17F "San
Antonio Rose" 41-24458 was the certain
victory which might mean it was seen to crash]
Significant, is that there is no report of damage to US a/c
by AA guns. However, heavy anti-aircraft guns were in action.
50th AA Battalion
Located at East Airdrome [Lakunai Airfield]. 0730 air-raid alarm,
2 B-17s, coming from south, alt. 5000m, out of range, couldn't fire.
Notice Japanese times are all 2 hours earlier than Allied "L" time
1030 - OP sighted 12 a/c, 5 B-17, 7 B-24, from 2700 direction, No.
1 & 2 secs opened fire, alt 3000m, enemy a/c broke formation while
dropping bombs. No. 3 sec opened fire on rear section of bombers, alt.
3500m. Nothing hit, enemy pursued by our fighters and disappeared to
the south. There is a sketch that shows no approach route but two withdrawal
routes both starting from NE Simpson Harbor (my estimate, no location
names included) one on about a 170 deg. track and the other about 135
deg. [their guns appear to be in range of this track]. Report continues. "No
crash." They suffered three wounded from straffing and bomb fragments.
They only expended 8 rounds.
15th Machine Cannon Battery
[Rabaul Harbor] Air raid warning 0730.
At 0735 2 B-17Es came in toward rabaul from the north (alt. approx.
5000m) "but because of our A/A fire they fled to SW. Note "our
A/A fire" probably relates not to the battery's machine cannon
(captured US .50's) but to heavy AA guns. Since the 50th apparently
only fired 8 rounds, this was probably mostly from the 39th.
1010 formation of 8 B-17s approached rabaul from NE (alt. approx 3500m)
and dropped several bombs in the harbor. No damage was sustained and
because of our A/A fire, they suddenly changed course and fled to SW.
Battery did not open fire as the airplanes were out of range.
39th AA Battalion
(Don't have ops orders or a war diary for them).
Had a false alarm but no raid on 6th. I didn't copy that
page for the 15th so I suspect there was nothing of interest on that
