== Description ==
 
<!--Write an introduction to the article in 2-3 small paragraphs. Briefly tell us about the history of the development and combat using the weaponry and also about its features. Compile a list of air, ground, or naval vehicles that feature this weapon system in the game.-->
 
 
 
The '''18-inch Mark XII''', or simply '''Mark XII''', is a British torpedo. Although designed for use as a aerial launch torpedo, it is used on some early Motor Torpedo Boats (MTBs), such as the [[MTB-1 1 series]].

== General info ==
 
<!--Tell us about the tactical and technical characteristics of the bomb.-->
 
The Mark XII is a relatively early torpedo. Deigned for aerial use, it has a lower weight and explosive mass than some other torpedoes, however it is relatively fast in the water.
 
 
 
The naval version of the torpedo has an optional "Torpedo Mode" modification which reduces the range from 3.2 km to 1.37 km, but bumps up the speed by 5 kph, bringing it to 74 kph.
 
 
 
=== Effective damage ===
 
<!--Describe the type of damage produced by this type of bomb (high explosive, splash damage, etc)-->
 
Like other torpedoes, when launched from a ship, the Mark XII can destroy just about anything smaller than a destroyer with a single hit (or even a near miss). It is possible for some destroyers to survive a hit from a ship launched Mark XII torpedo, and cruisers can almost always take multiple hits from a Mark XII without being destroyed (the torpedo will still start major fires and hull breaches, but won't instantly hull-break the ship).
 
 
 
Air launched Mark XIIs seem to be more powerful and can often destroy cruisers (of the player controlled variety) in a single hit.
 
<!--TODO: Add description of destructive power against Air RB ground targets-->
 
 
 
=== Comparison with analogues ===
 
<!--Give a comparative description of bombs that have firepower equal to these type of weapons.-->
 
The closest comparison to the Mark XII (with regards to naval battles) is the German [[LT 1A/1]] (also a 45 cm torpedo found at reserve rank). By comparison, the Mark XII is much faster, however the German torpedo has a larger warhead. The Japanese [[Type 2]] (a 45 cm torpedo found on the Japanese reserve ship) is an all round better torpedo, being both faster and having a larger warhead.
 
 
 
Compared to the larger American [[Mk.8-3 C/D]] 53 cm torpedo (found at reserve rank), and German [[G7a]] the Mark XII has much better speed but a smaller warhead.
 
 
 
== Usage in battles ==
 
<!--Describe situations when you would utilize this bomb in game (vehicle, pillbox, base, etc)-->
 
The Mark VII is relatively fast compared to other low rank torpedoes in naval battles and has a compatible range, allowing you to hit further away targets easier.
 
 
 
When dropped from aircraft the characteristics of the Mark XII are not ideal. You are required to drop below 105 m and decrease your speed to below 281 kph.
 
 
 
=== Pros and cons ===
 
<!--Summarize and briefly evaluate the weaponry in terms of its characteristics and combat effectiveness. Mark pros and cons as a list.-->
 
'''Pros:'''
 
* Good speed
 
* OK range
 
 
 
'''Cons:'''
 
* Poor airdrop characteristics
 
* Below average explosive mass
 
 
 
== History ==
 
<!--Examine the history of the creation and combat usage of this weapon. 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: <nowiki>https://wiki.warthunder.com/(weapon-name)/History</nowiki>) and add a link to it here using the <code>main</code> template. Be sure to reference text and sources by using <code><nowiki><ref></nowiki></code>, as well as adding them at the end of the article.-->
 
 
 
The Mark XII was designed in 1935 (and entered service in 1937) as an aerial torpedo for use by the Fleet Air Arm and RAF Coastal Command. It was a development of the 18-inch Mark XI, which had a larger 211 kg warhead (compared to 176 kg on the Mark XII), but a shorter 2,300 m range and lower speed of 35 knots (65 kph). The Mark XII reduced the warhead size, but increased the speed and range to 69 kph at 3,000 m range or 74 kph at 1,400 m range.
 
 
 
The torpedo was 4.95 m long, 450 cm wide and weighed 702 kg. It was powered by a 140 hp burner-cycle engine.
