RESULTS:
(For all claims
made on ship targets of special interest, draw diagram, top or side view
or both, as appropriate, showing type and location of hits. For
all targets give location and effect of hits, and identify by number
above. Use additional sheets if necessary)
1. Three planes fired 9 75mm shells on glide into target the first
shell fired at a range of 6000 yds. Three shells were observed
to hit in or very near the gun emplacement. Bombs were released
after leveling out from glide at 1500'. Four were short and went
into the ocean, the other eight were long hitting near the west shore of
the island.
2. Three planes approaching target on a heading of 270°
and downwind fired 11 75mm shells starting at a range of 6000 yds.
Seven hits were observed on or very near target. Bombs were
dropped in level flight at 1500 feet, four hitting within 200 feet of
the target and the remainder being long.
3. Three planes fires 11 75mm shells in a glide opening fire at
6000 yds. Eight hits were observed in or near target. Eight
bombs from two planes were dropped in close groups immediately north and
west of target, the remaining four were long.

Nine planes of this
squadron and an F4U photo plane from VMF-111 took off at 0800 and joined
up over the field. They then flew a course for the south tip of
Likiep Atoll. The formation on the flight out was a V of V's and
the planes climbed to 7000 Feet altitude between the base and the target
at I.A.S. of 140 knots. From Likiep the flight turned due east and
the formation moved from a V of V's to a left echelon of V's. The
flight passed abeam of Wotje and proceeded east for 2½ minutes.
The first section then made a 90°
turn and flew south to a point directly opposite the center of the
target. At this point the first section made another
90°
turn, and began its run over the target, the three planes spreading out
so that one plane covered each of the three targets. The other two
sections followed in order using the same tactics. The planes
coming out of the sun and downwind, picked up speed in their glide until
I.A.S over the target at 1500' was 250 to 270 knots. 75mm were
fired from 6000 yards until bomb range was reached and than 4 500# bombs
per plane were released over the target. Upon completion of its
run the first section made a right turn and circled in order to cover
the photo plane on its run. The remaining two sections turned left
and proceeded to the rendezvous point which was at 1500' over Erikub
lagoon 20 miles south of the target. As soon as the third section
had cleared the target the photo plane made its run from north to south
at 2000 feet and about 400 knots. The first section and the photo
plane then joined the other sections at the rendezvous
point reforming into a V
of V's and returned to base at 1500' and 140 knots landing at 1040.

The sight unit of the
A.P.G.-13 on one plane came loose from its mounting and fell to the deck
of the pilots compartment. Later investigation revealed that the
shock of firing the 75mm cannon had loosened the connection between two
parts of the sight. No damage was done and the part has bee
reassembled. |
