[TEC] Mark 27 power...

Redwine · 04-10-07, 10:43 AM

Hi all ...

Is/was this torp so enough powerful to kill a DD in real life ?

Looking historical data, it was filled with only 42kg of Torpex... not too much explosive in comparison with 292kg of Torpex from Mark 14 and 23, 261kg from Mark 18, 428kg from Mark 16......

How does it worked ?

Was this torp inttended to kill/sink a DD or simply to destroy its proppellers using the acoustic homming ?

I note, it is overpowered in the sim files in comparison with the other torps.

Any info, comment, siggestion... is welcome !

It was also very small and very slow. Here is a description of characteristics and use:

Ship Class Used On: Submarines
Date Of Design: 1941
Date In Service: 1943
Weight: 720 lbs. (327 kg)
Overall Length: 7 ft 6 in (2.286 m)
Explosive Charge: 95 lbs. (43 kg) Torpex
Range / Speed: 5,000 yards (4,570 m) / 12 knots
Power: Battery
Notes: A variation of the airborne Mark 24 adapted for submarine use. It was a passive homer intended for self-defense against ASW escorts. Used only against the Japanese. A larger version, the Mark 27 Mod 4, was capable of 15.9 knots and was in service from 1946 to 1960.

Many thanks for atention Sailor Steve !

The matter is...

Was it capable to sink a ship ?

If not, what was its real use ? to destroy ship proppellers ?

According with data... it has 12knots max speed, then, it is not a good option to shoot ot at the back of a DD, the torp will neaver reach the DD...

Then... how was it used in real life, was it shoot infront of the DD to an incoming DD ?

According to http://www.fleetsubmarine.com/torpedoes.html:

"These were 19-inch models, and carried a very small warhead (92 pounds for the Mark-24, 95 pounds for the Mark-27). In the original anti-submarine role this was enough, since it only needed to punch a small hole in the pressure hull and water pressure would take care of the rest. In the anti-escort role, the "Cutie" would home in on the escort's screws, and the small warhead was likely to be enough to blow off a screw and put the escort out of action. It wasn't necessary to kill an escort so long as you could get it stop trying to kill you."

Also as I recall Uncle charlie himself was very hot to get cutie into the
war as a subchaser wasnt worth a big torp.

Dont take this the wrong way, but "any hole is a good hole"

You punch a hole in any hull the crew will need to fix it.

Well, having served on a destroyer I can say this: the standard for all hulls was about 1/2" thick, and external armor plate wasn't much good against torpedoes anyway; hence the anti-torpedo bulges for large warships. Also a destroyer doesn't have a whole lot of compartments, so the chance of hitting a magazine isn't too bad, and the engine and boiler rooms are quite large, so a hit there not only puts the propulsion out of service but also lets in a lot of water.

It might not be much, but in a pinch I'd take one.
