New Torpedoes

[andycaccia]

Yes, I feared this...oh well, it wasn't essential anyway.
I have to reinstall sh4, and then I will do some testing wit torpedoes.

The USN developed the Mk 18 into an acustic homing torpedo. The Mk 28 was actually aboard subs that were working around Japan in 1945. I am so new to this game, so I don't know how to mod a torpedo, but Like the USS Batfish on her 7th War Patrol around Kyushu Island in 1945, I would love to have the Mk 28 torpedo.

The USN Mk 28 Torpedo had the following stats

Range: 4,000 yards (3,650 meters)
Speed: 19.6 knots
Warhead: 585 lbs of Torpex
Diameter 21 inches (53.3 cm)
Length: 20 ft 6 in (6.248 m)
Weight: 2,800 lbs
Poer: Electric Battery
(like the Mk 27, the 28 used acustic sounds from the enemy's ship to home in on)

The MK 18 had the following

Range: 4,000 yards (3,650 meters)
Speed: 29 knots
Warhead: 575 lbs of Torpex
Diameter 21 inches (53.3 cm)
Length: 20 ft 6 in (6.248 m)
Weight: 3,154 lbs
Power: Electric Battery

My question is can one of our talented modders make a torpedo we can add to the game using the Mk 18 as the base and giving it the homing ability of the Mk 27

Got this from one of the website posted above...

The Mk.28 was a 21" x 246", 20 knot, submarine launched anti-surface vessel torpedo with a 585 lb warhead. It was equipped with passive homing and gyroscopic control which competed for rudder control. About 1750 of these torpedoes were produced by Westinghouse and Western Electric. Only fourteen were fired with four hits during WW II, but the torpedo remained in service until 1960.

I'm guessing that the devs felt it was under-utilized and didn't make any real difference in the war. Probably same thinking that caused them to leave out the Tench boats from the game.

[CinC Battleforce]

Bad thinking on their part. Both the Tench class boats and the Mk 28 torpedo were the state fo the art in 1945. And well they should have included both the boat and torpedo in the game just for the sake of being acurate.

[andycaccia]

Yes indeed it was a non accurate approach of the developers while making the game, as well as the same 450ft depth gauge on all boats when later gatos and all balaos had a 600ft one (fortunatly we have a mod to restore this). However a tench-class mod with start campaign in 1945 has been made. It uses the same balao model but tweaked a little in strength and with 2 torpedoes more in the forward reserve compartment.

It would be a nice adtition the mk 28 as you say, but i fear that adding new torpedoes is far more difficult than adding a new submarine.
I'm still working on this...

I know that modern torpedoes are wire guided. On an unrelated note can one edit the torpedo skins to add writing on them such as "To Tojo, From USS Drum"

[AlmightyTallest]

Man it would be great to get Mk 28 homing torpedoes to go with the Tench Class Ducimus made.

It seems like all of the ingredients are already there, wakeless electric Mk 18's and the the homing abilities of the Mk 27 combined into a neat torpedo option for late-war ships.

For fun, found this photo of the Mk-27 Cutie at the USS Pampanito site here: http://www.maritime.org/wish-mk27.htm I'm guessing that's the real paint scheme for the Mk-27?

Also, for those interested here's a link about the development of U.S. acoustic homing torpedoes from 1945 to 1950, it's very interesting reading. http://www.personal.psu.edu/pq9/post.html

And finally, a report from the USS Torsk (Tench Class) https://www.usna.com/NetCommunity/SS...=636&srcid=502


"Early that day a merchant ship escorted by a single frigate was sighted. The captain decided to sink the frigate first with a new type of torpedo which homed in on a target’s screw noises. Torsk was one of the first submarines to get this new, secret Mk. 28 torpedo. The captain fired one torpedo which we saw hit the target’s stern and lift it up 45 degrees. A number of lifeboats were seen picking up the survivors and luckily for them they were only a few miles from shore."

"
The merchant ship headed toward a nearby port at full speed. Before we could get in a good position to fire torpedoes, it entered port. Our captain said maybe we should surface and fire at it with our 5 inch gun, but fortunately decided against it when a Japanese warplane appeared headed to our area. Soon more ship sounds were heard and we saw another frigate bearing down on us. The aircraft apparently saw Torsk and called in the frigate. The frigate apparently saw the periscope because he was heading directly toward it.
Another acoustic torpedo was fired at the frigate even though the acoustic torpedoes were designed to be fired from aft a target’s beam and the present target was heading directly toward us. The torpedo was fired when the target was about 2000 yards away and Torsk went deep to evade and hoped the torpedo hit. After what seemed to be an eternity, a loud explosion occurred very close to us, accompanied by breaking up noises. If that torpedo had not hit, there would have been a bad depth charging. They sent another frigate out to try to locate Torsk, but it was quite easily evaded after it had dropped a few depth charges - fortunately not close."
