Enemy Sub Sunk

[darqen27]

I know they subs are rare to run into, I found this jap submarine, and he was quickly sunk by 2 torps

Nice job there. (enemy) submarines are my favorite ship to sink. Just feels so good for me :P. Too bad they are so rare, but then again guess that makes it much funner when you find one!

Great job on the enemy sub! Watch their deckgun though! If you can get in close, one torpedo does the trick.

So far, I have found them in that little passage W/S/W of Tokyo, south of Makkassar Strait, on a parallel line if you draw it on your map, it would be mid-way between Borneo, and Java. Also, the shipping route brteen the Palau Islands, and Rabaul will turn them up every now and then, but the most I have seen of them is the area around Luzon Strait, and just west of there. Not much tonnage for them though.

A good thing the Japanese Navy never used their subfleet as aggressively like the US Navy did.

I found one about 100 nm north of the Lomboc Strait in Jun '42. Hit it with one torpedo but it wouldn't sink. So I rammed before it could dive. My sub slid over the top with no apparent effect.

Although I received no credit, on the whole it was a worthwhile experience. I got a good look at the Japanese sub commander. He was dressed in a fancy bright green uniform, like a Shriner on Christmas....

An old thread here mentioned that one receives credit for these subs only infrequently when they sink (or, crash dive).

Great screenshot, btw!

Very nice job. I bagged one the other evening near Wake Island in Feb 1944.I was there as lifeguard for a PB4Y strike from Midway(happened in real life, inserted it into RSRD) , one morning after the strike while heading to look for a liferaft near a crash marker on the navmap, an IJN sub came along at 12 knots, was a long approach and could not get under 2,000 yards before had to fire Mark 14's, but a spread of 4 did the trick when she zigged to avoid, one caught her in the stern, she blew up nicely and sank.

Good job.:salute:

This one was south of the choke point in makassar strait

Do they actually dive? , or are they just on the surface lke in Sh3 ?

They just stay on the surface. I went with one head to head with one in the Celebes sea in 1945 last night (deck guns only) took some time but she went down.

Indeed this has been discussed here before, and nobody recollects seeing a jap sub diving. They just stay in the surface, cruising. I once saw one of the large i-400 docked. Apparently the game treats them as just another ship.

I would love to fire only 1 torp at something and watch it sink, but the mk 14's have taught me to fire in pairs, or 4's for that matter

History of Japanese Submarines in World War 2.

Japan had what was easily the most diverse submarine fleet of any nation in the Second World War. These included manned torpedoes, midget submarines, medium-range submarines, purpose-built supply submarines (many for use by the Army), long-range fleet submarines (many of which carried an aircraft), submarines with high submerged speed, and submarines that could carry multiple bombers.

Because of the vastness of the Pacific, Japan built many boats of extreme range and size, many of which were capable of cruises exceeding 20,000 miles and lasting more than 100 days. In fact, Japan built what were by far the largest submarines in the world, indeed, the only submarines over 5,000 tons submerged displacement, or submarines over 400 feet in length until the advent of nuclear power. These same boats were credited with a range of 37,500 miles at 14 knots, a figure never matched by any other diesel-electric submarine. These large boats could each carry three floatplane bombers, the only submarines in history so capable. Japan built 41 submarines that could carry one or more aircraft, while the vast submarine fleets of the United States, Britain, and Germany included not one submarine so capable.

You think it would have been an obvious expansion for the game to have a Japanese sub campaign!... Surface the boat for bombing run!!! :Kaleun_Salivating:

Fire plane from the top tube!

[Hylander_1314]

Actually, they carried float planes. Rather interesting!

Interesting short read on them.

You would think instead of their cheap "U boat missions" in 1.5 they would have put in an IJN campaign, but its UBI.Of course, I dont trust them to make a decent out of the box game, once the SH community modders get a hold of the game for a while, then it becomes playable.

[RudderBob]

I ran across one of those jet subs, fired about six torpedoes into it what a waste it would not sink it just sat there

[Soviet Creeper]

Those plane carrying ones are buggy in stock I heard. I THINK ive sunk them with one or 2 torps using RFB. My memory may be bad though

History of Japanese Submarines in World War 2.

You also have to look at the dark side of why the large and impressive looking Japanese submarine fleet accomplished such meager results in comparision to the Germans and Americans.

Although there is no evidence that the Japanese had any qualms about attacking merchantmen, Japanese submarine doctrine strongly emphasized attacks on warships. This was in keeping with the Japanese focus on the decisive battle that was supposed to be fought between the main Japanese and American battle lines somewhere in the Western Pacific. In order to compensate for the anticipated numerical superiority of the American fleet, the Japanese planned to wear down the Americans with attacks by submarines, light surface forces, and aircraft as the American Fleet crossed the Central Pacific. As a result, Japanese submarines did not initially concentrate against the long and vulnerable Allied supply lines.

This was unfortunate for the Japanese. Although their submarines had some notable successes during the war, particularly the sinking of the Wasp during the Guadalcanal campaign, the employment of Japanese submarine forces was characterized by inflexibility and indecisiveness. A particular weakness was the use of ever-shifting picket lines, which persisted long after these had proven vulnerable to Allied hunter-killer groups, which were often guided to their victims by Ultra intelligence. Some of the poor management of Japanese submarine forces may have arisen from the fact that the submarine staff officers, even at the highest levels, were no higher in rank than commander, and so had little clout.

Another misuse of Japanese submarines was their employment in transport operations to isolated garrisons. This became the major activity of the submarine force after 16 November 1942, when all available I-boats were placed under the command of Mito Hisao at Rabaul to carry out supply operations (mogura, "mule", operations) in the Solomons and New Guinea. A seaplane-equipped I-boat could carry more than fifty tons of cargo in place of its aircraft facilities. However, the runs were extremely unpopular with the submarine crews, whose morale plummeted. With their hangers being used as a cargo hold, Japanese submarine seaplanes saw little use after this point and were usually assigned to shore duties.

From November 1944 on, the emphasis switched again, this time to the use of Kaiten suicide torpedoes against Allied bases or (from April 1945 on) sea lines of communication. This proved costly and ineffective, with several of the mother ships sunk before they could deploy their Kaiten.

I've seen several Japanese submarines docked in port but I've never shot at one. Do you even get any tonnage for sinking one?

I would say that the japanese knew that the allied merchant fleet passing under the range of their sub bases were not so vulnerable and accessible to their subs in many aspects. This may explain their primary target being warships.
