End of July was very poor for submarines performance. Bass, S-43 and S-45 did not made a contact with enemy, three other boats coudn't take a good attack position and left with nothing. So six of ten boats did not fire even one torpedo this week.
Four other boats, also achieved nothing. S-23, S-19 missed all targets, S-30 badly damaged one, and only S-28 sunk single 2000 tons freighter.
This week total: 1 ships sunk, 2000 tons

Argonaut after targeting big 20000 tons ship, was forced to crash dive and stay there till convoy was safe way away.
S-40 after detecting fast task group is able to sink 3000 tons maru. In the same group she rapported Kongo class battleship.

Torpedo investigation shown drastic numbers: 70% of all torpedo attacks, missed the target!
This numbers showing definitely problem with torpedos. Bad attack position, wrong calculation, wrong torpedo setting and malfunction, without doubt have some procentage in this calculation, but there must be a other, concealed problem. Raport was send to High Navy Command, with request to re-test torpedo effectiveness.
Single score this week, belong to S-47. Patrolling South Chine Sea, she sunk medium 3000 tons merchant, from small convoy.
After more then two months in repair, S-28 return to service. She was damaged and forced to dive by destroyer, when gun attacked big 9000 tons supply ship.

With only four submarines on patrol this week, two made a score. S-44 during quick hit-and-run attack, sunk medium 3000 tons ship. Near Marianas S-34 sunk big 5000 tons merchant, in first salvo.
This week also S-19, moderate damaged on patrol and S-48 with lightly damaged, left the docks. Fully repaired, both returned active service.
Another three boats moored in Pearl Harbour this week, to reinforce our submarine fleet on Pacific. Argonaut, S-45 and S-46 after refuelling, are reassigned to Philippines base in Manila.

Angry captain of S-44, as a first, rapported torpedos problem. On his patrol he took perfect attack position on huge 16000 tons tanker. Torpedo salvo missed, a too long ship to be missed,attacked from just 500 meters. Stunned captain, ordered second salvo into another closest massive 9000 tons supply ship, to unbeliveable missed again. Frustreated, he radioed the complains. Many of other boats captains confirmed the problem. I ordered more rapports from captains.
Meantime S-1 on South China Sea spotted small convoy. During the night attack, medium merchant appeared from nowhere and crossed the torpedos path. Burning 3000 tons ship, helped to hit another maru. Both damaged ships sunk shortly after for total 8000 tons.
Another success belong to S-39. After chasing the small convoy, she sunk big 5000 tons merchant on Philippine Sea.
I am really pleased from this week performance, 13000 tons sunk this week is a big success. Till this week our total was 27000 tons, so in one week we sunk half of 10 weeks work total. I only hope that week was not a last one.

Turn 9: Bombardment of Okinawa

9 boats on patrol

4 boats in repair
Due to bad results in last few weeks, US Navy Command started to consider different way to employ the submarines in war. One of the first ideas was to use them to bombard the port facilities. During the night two submarines should surface near the Okinawa port and start gun fire, then escape unseen. To this job were designated Narwhal and S-36. On night, sunday 17th of June, passing the dangerous approach to port Narwhal surfaced in randezvous point. At midnight she started her bombardment of Okinawa port facilities, firing her two 6" guns. After expended 127 shells, she slip back to open sea. Unfortunately S-36 never appeared in randezvous point, she was lost on the way. She is a fourth lost boat in War.
Other boats on patrol hit two ships. S-47 small 1000 tons maru, and Bonita medium 3000 tons merchant.
This week total: 2 ships sunk, 4000 tons

6 boats in bases
2 boats in repair
After sixth in the row dry week, I started to doubt in My tactic. Rapports shown the only one ship was destroyed in reattack on the same convoy, but 6 submarines was damaged and one sunk. That gived Me a conclusion that reattack is too dangerous for now. Boats in repair wasting time, which could be productive on patrol. With so many returning submarines with damage, I decided to allow to reattack only if the situation is really safe or important.
I also started to worry about sunk tonnage. With only 23000 tons after 8 weeks, what gives average 2875 tons per week. In this tempo I should only reach less then 100000 tons to the end of the year, which is extremely low. I will wait to the end of the month, and then rethink this problem.
This week total: no ships sunk
