TO: Submarine Commanders, SubRon 4A FROM: ComSubPac / ComSubRon 4A DATE: September 1942 SUBJECT: Mission Orders ( Cycle 4, June
2002 ) RMKS: 1 A blockade of Truk is in effect,
all boats in the vicinity are to intercept and inflict maximum damage on all
IJN capitol ships and merchants headed for the Solomon Islands. These are
moving south from empire waters to the Solomons via the Mariana Islands, Palau
and the Caroline Islands. RMKS: 2 ONI believes that Admiral
Yamamoto, CinC IJN, is using Truk as his headquarters and is determined to
force the U.S. forces out of the Solomons once and for all. It is believed
that he has assembled a formidable force consisting of four carriers, five
battleships, 14 cruisers and over forty destroyers for this purpose. All boats
in the Caroline, Palau and Solomon areas are to use extreme caution,
anti-submarine activity is anticipated to be very intense. RMKS: 3 IJN Submarine activity is
expected to be heavy in the Solomon area and all boats are to be on the alert
for these targets moving south from Empire waters south to the Solomons. RMKS: 4 The air-sea battles of early June
resulted in a tremendous victory. The Japanese surprise attack and planed
invasion of Midway was defeated and turned back short of their target. But the
enemy has successfully occupied American territory in the Aleutian Islands. RMKS: 5 BuOrd positively confirms that
the MK XIV torpedo is running below optimum depth setting, All commanders are
hereby authorized to adjust settings accordingly. The MK VI magnetic exploder
will continues to be employed during all attacks on the enemy. RMKS: 6 An advanced Submarine base has
been established at Midway Island. This refitting and re-supply facility will
reduce the round trip voyage to Empire waters by 2,000 miles thus allowing more
time on station for patrol. RMKS: 7 Combat testing of a NEW
surface Radar system has been successful. The SJ Radar will provide exact
range and baring to target thus enabling us to See at Night and during
rain and fog . As these set become available your commands will be fitted
with these new sets. RMKS: 8 SubRons are assigned to the

getting to his assigned patrol area he is to pick another area close to his
assigned AO and inform his SubRon CO and ComSubPac as to the change. ( this is
only if PZ Pick will not pick the area originally assigned.) All commanders are to Acknowledge receipt of these
orders.. Good Luck and Good Hunting CMDR. Greg Turner II CO SubRon 4A Rear Admiral Robert H. English Commanding submarines Pacific // SENDS //
