=== Survivability and armour ===
 +
Although the armour is weak ( hull armor 15mm of steel and citadel 4 mm steel, in result is 40mm), the survivability is not that bad as it is a very long boat. If the engine gets hit, you fire back. If the guns get hit, You get to cover. But lets face it,its overall armour is weak.
 +
 
 +
So, the boat has just a little bit of armor plating, so its not goin to do anything for you at CLOSE RANGE.
 +
 
 +
But because of the guns are laid at you can  do fairly effective broadsides at long range.

The '''{{PAGENAME}}''' torpedo was a guinea pig of a torpedo having been the subject of testing and modification since 1925. Used early in World War II, this torpedo failed to operate properly approximately 70% of the time with problems of running cold (propeller mechanism failed to start), sinking, not running true (deviating path), improper depth, running on the surface or porposing (continuous jumping out of the water) due to improper water contact. Aircraft were required to fly extremely slow and low when dropping the torpedo as to not damage it on impact with the water and to provide the most stable drop possible, unfortunately, this put the torpedo bomber in a bad position of being an easy target for anti-aircraft guns mounted on enemy ships.
 
  
Extensive testing in 1942 determined that the low and slow approach to the Mk.13 launch was actually counterproductive as it caused the torpedo to “belly-flop” on the water resulting in damage sustained to its internal components. New modifications were tested which replaced fragile parts and components which were susceptible to damage upon impact with the water.<ref name=NAO></ref> Updates to the torpedo allowed it to be safely dropped from a higher altitude and at faster speeds. By 1944 the Mk.13 was essentially a brand new torpedo and was accepted as the best aircraft torpedo in the U.S. inventory at that time and was credited with the sinking of the Japanese battleship Yamato.<ref name=NavWeaps></ref>

targeting speed: 17°/sec
  
Later after World War II, there came a need for river patrol boats to be outfitted with torpedo launchers. The Mk.13 was the ideal torpedo to fulfil this need due to its short stature (compared to other torpedoes) and excelled in a shallow launch and run which afforded it to operate in shallow waters without hitting the bottom. Opportunities for sea use on smaller vessels were available in shallow areas where larger ships and torpedoes could not operate.

These can be used as a close range weapon although they only fire behind you. THESE ARE NOT MORTARS.
<!--''Tell us about the tactical and technical characteristics of the torpedo.''-->
 
The aircraft torpedo Mk.13 is typically carried on attack-type aircraft, however, there are a few light bombers which can also be outfitted with them. The design of the Mk.13 departed from conventional torpedo design for submarines and destroyers to accommodate being delivered by aircraft and being dropped.<ref name=NavWeaps></ref> Due to the short and stocky size of the torpedoes, they were also ideal to be outfitted on motor torpedo boats where they could either be launched from tubes or just rolled off the side of the boat for more stealthy approaches.  
 
  
The appearance of this torpedo is similar to many others in that it has the appearance of a mini-submarine which contains an engine, fuel and steering devices. At almost one ton in weight, 600 lbs of it is the detachable warhead which is filled with the highly explosive Torpex.<ref name=NAO></ref>
+
information: Mass: 194 KG
  
The Mk.13 torpedo was specifically designed to be used from an aerial platform with a range of 5.7 km with an in-water speed of almost 67 kph. The Mk.13 designation applies to the entire torpedo assembly as a whole, however, portions of the torpedo (warhead, gyroscope and other sub-assemblies) will have their own mark and mod designations.
+
Explosive mass: 130 KG
  
=== Effective damage ===
+
Price 40 SL for 4 depth charges
<!--''Describe the type of damage produced by this type of torpedo (high explosive, splash damage, etc)''-->
 
The Mk.13 torpedo had a large high-explosive warhead compared to the Mk.VII which was frequently used at the time. The Mk.13 had a 600 lb (270 kg) Torpex (Torpedo Explosive) warhead compared the Mk.VII’s 466 lb (211 kg) warhead. Torpex was an explosive which was about 50% more powerful than TNT by mass alone as this mixture contained 40% TNT, 42%  RDX and 18% powdered aluminium. While not as fast nor had as long of range as other torpedoes, the Mk.13 was used effectively at night when stealthy operations from PT boats which took place requiring torpedoes to reach the target with the least amount of warning. Aerial operations took advantage of the slower torpedo by dropping it from a higher altitude, increasing its time in the air and getting it closer to the target before it entered the water.<ref name=NAO></ref>

Try to stay at long range, where your guns and armor work good together. At close range try to angle, the downside is you will only be able to use the front guns or maybe back guns, so long range is the best play here.
The upgraded Mk.13 torpedo can be utilised against any target which is in the water which can include ships, boats, tanks (at the water's edge), boat-planes or even structures. Due to the higher altitude in which it can be dropped from, the delivering bomber can make a safer approach, release and get-away avoiding ship-board anti-aircraft fire and fighters patrolling around ships.

try to be sneaky with your boat, if spotted you will be guaranteed dead, or damaged heavily.

So i recommend coming close to the ship as the armor is weak, only downside, you will get a shower or 20 mm guns and a 37 mm gun. The main gun needs some time to turn, so a quick execution is needed

* Aircraft typically only carry one or two at a time

History

Describe the history of the creation and combat usage of the ship in more detail than in the introduction. If the historical reference turns out to be too big, take it to a separate article, taking a link to an article about the vehicle and adding a block "/ History" (example: https://wiki.warthunder.com/(Vehicle-name)/History) and add a link to it here using the main template. Be sure to reference text and sources by using <ref>, as well as adding them at the end of the article.
