Description

The 533 mm G7a is a standard-issued torpedo of Germany's Kriegsmarine. The G7a and its variants were widely used throughout the World War II and can be found on almost every Kriegsmarine bluewater ships in the game.

General info

The G7a is filled with 358.4 kg of TNT equivalent. The torpedo can travel up to 6 km at 81 km/h in normal mode, and 14 km at 56 km/h with "Torpedo Mode" modification.

Torpedo characteristics
Torpedo Mode	Mass (kg)	Maximum speed in water (km/h)	Travel distance (km)	Depth stroke (m)	Arming distance (m)	Explosive type	Explosive mass (kg)	TNT equivalent (kg)
No	1,528	81	6	1	50	SW39a	280	358.4
Yes	1,528	56	14	1	50	SW39a	280	358.4

Effective damage

The G7a's warhead is able to hull break any destroyer-sized ship with a single hit, while it can cause considerable damage to cruisers depending on where it hits.

Comparison with analogues

Give a comparative description of torpedoes that have firepower equal to this weapon.

Usage in battles

The G7a is a basic run-off-the-mill torpedo with decent overall performance. The warhead of ~360 kg can pose a threat against most of the targets short of some capital ships. However, it suffers from its polar opposite performances with and without the "Torpedo Mode" modification installed, which can cause it to be less effective in certain maps.

Without the "Torpedo Mode" modification installed, the G7a has a high travel speed of 81 km/h, which allows it to be effectively used as an ambush and close range weapon, albeit its limited range of 6 km renders it useless in open maps. On the other hand, the installed modification significantly increases the range to 14 km at the cost of reducing its top speed to only 56 km/h, making it a good area denial weapon in open maps, but performing terribly at close-quarters combat.

For coastal vessels, it is always recommended not to install the "Torpedo Mode" modification, as the 6 km range is still sufficient for a smaller boat. For bluewater ships, the usage of the "Torpedo Mode" modification depends on the playstyle of each ship and how you can take the most advantage out of it.

Pros and cons

Pros:

Sizeable warhead of ~360 kg TNT equivalent can deal a considerable damage against enemy ships
Fast travel speed when not equipped with torpedo mode, long range when equipped

Cons:

Average performance compared to its contempolaries
Short range without torpedo mode, equipping the modification will significantly reduce its travel speed

History

German Torpedoes manufactured prior to the end of World War II were designated as to their diameter, length and propulsion. Modifications were usually, but not always, denoted by T numbers. Length was to the nearest meter. For example, the designation G7a meant that the torpedo was 53.3 cm (21") in diameter, was about 7 m long and had a wet heater motor.

Letter	Diameter	Suffix	Propulsion
F	45 cm	D	Dampftorpedo (wet heater, World War I)
G	50 or 53.3 cm	a	Air/steam (wet heater, World War II)
H	60 cm	e	Electric
J	70 cm	u	Hydrogen peroxide
M	75 cm

This torpedo is using SW39a explosive. Number indicating year of adaption. It was composed of TNT, Hexinit (HND), Ammonium Nitrate and Aluminum. Content of aluminum powder was increased from previous versions (SW36 and SW39) to increase shock wave.

Excellent additions to the article would be video guides, screenshots from the game, and photos.
