Description
The S-100-class, S-147 is a rank III German motor torpedo boat with a battle rating of 2.7 (AB/RB/SB). It was introduced in Update 1.79 "Project X" in the fleet closed beta test.
General info
Survivability and armour
The S-100 (1944), as with most vessels of the same type, does not have much in the way of armour. It has 12 mm of hardened armour protecting the bridge, 8 mm on the centre 20 mm Flakzwilling cannon mounting, and another 12 mm on the rear mount. Survivability is about average, with a slightly larger size helping with its crew distribution. The craft, as with any other like it, has a weak propulsion system, and thus can be immobilized by a nearby bomb or rocket explosion. All of the other components are average, with the ammunition providing a small area to hit, making ammunition detonations rare. As with most vessels, its gun turrets are rather weak, with the bow 30 mm being sometimes knocked out after a simple frontal engagement with an enemy (though this is far more unlikely), and the larger 20 mm turrets being frequent impact points of enemy fire. The gun shields covering the 20mms may deflect or absorb a stray low caliber shot but do not rely on them to protect the turrets.
Mobility
The S-100 across all variants is a very mobile platform, and this variant is no exception. The craft has a top speed of 78 km/h, and a reverse speed of 23 km/h, when spaded. The S-100 can generate plenty of thrust as it has 3 decently sized propellers, each connected to a 2,000 hp Daimler-Benz MB-501 engine.[1] From this, it has great acceleration and deceleration, being able to accelerate and decelerate fast enough to evade enemy fire and prevent collisions. It has a quick rudder shifting speed, being able to rapidly change direction to evade obstacles and fire, and is slightly better than most other boats of the same displacement.

Armament
Primary armament
The primary armament consists of a single 30 mm MK103/38 mount in a swivelling turret, situated at the bow (front) of the vessel. This mount can be easily underestimated, as the previous boats of similar design in the tree have had a much weaker armament placed in this mount, and thus it can be easily overlooked. However, this is a mistake. Given the BR the S-100 (1944) is positioned in, heavily armoured targets are few and far between, and lightly armoured craft are in abundance. This is the premise at which the MK103/38 takes its prey. The MK103/38 does not have an excelling fire rate, being slightly under average than other armament at its level. It also has a below average reload, feeling slightly sluggish compared to other armament, such as the 20 mm MG C/38, which can be found on the same mounting on the previous boats in the tree. The ballistics of this weapon are nominal, with noticeably mundane trajectories which are easy to predict, a result of the higher calibre and thus better energy retention of the shells, however shots can be all over the place from the bad shot dispersion of the gun. As for the shells themselves, the HEIT shells featured in the clips of the 103s are deadly to even the larger spectrum of vessels to be encountered. These shells are prone to setting fires and inflicting thorough HE damage on a craft's hull and superstructure. The API rounds are also good for punching holes in an enemy vessel and blowing up inside. Given this, the best ammunition belt to equip the S-100 with would be the Universal belt, as it has a good balance between HEI and API; the HVAP rounds are not effective, as they over-penetrate without inflicting major damage. This weapon shows utmost efficacy in detonating ammunition stowage, so aiming for the front of enemy vessels, where it's placed on a lot of craft, is a viable strategy. All-in-all, a prestigious weapon.
Secondary armament
The secondary armament on the S-100 (1944) are two 20 mm autocannon turrets, one in the middle in a dual-mount and another closer to the stern in a quad-mount.
Surface engagements: Surface targets can also be effectively engaged with the 20 mm guns. As the main armament only consists of a single cannon, many find it more desirable to utilize the secondary armament with a more primary armament role. The reason players choose this is because of the greatly increased fire rate and mass of fire from the 20 mm cannons over the 30 mm. This results in the 20 millimetres being much better suited in the tactic of "spray and pray" than more precise shooting, due to the abundance of fire they produce. They can be useful, even when mainly using the 30 mm, in situations such as when a group of lightly armoured enemies are presented, where a mass of fire is better suited to the job than the slow-firing 30 mm gun. They can also perform well in close-quarters situations, where the 30 mm may deplete its ammunition before an enemy is destroyed, and thus one can alternate between the former and the 20 mm cannons.
Anti-air engagements: The S-100 (1944) has proficient armament in dealing with air targets. It carries a total of six 20 mm guns which all have broad fields of fire facilitating the engagement of enemy air targets. The 20 mm guns are best used for anti aircraft purposes, as the 30 mm can be used to take out most surface targets. These guns have adequate velocity, and do well in getting shots on target with abundant fire erupting from the vessel when an aircraft gets too close. However, it should be noted that these guns do not have good range, and usually project a high firing arc.
Anti-aircraft armament
The anti-air armament of the ship is made up of two 7.92 mm MG15 machine guns in two separate single-mounts on the bridge.
The MG15s can be of limited use as they do not pack the firepower, or the lack of fire restriction, which the twenty millimetres have. The MG15s are almost useless against surface targets, due to these limitations compared to the 20 mm. If anything, they are simply there to supplement the available firepower on the boat.
Additional armament
The S-100 (1944) carries four 533 mm G7a torpedoes in two tubes situated on either side at the front of the craft, facing forward with spares located directly behind. The torpedo tubes are pointed directly forwards, with no spread to any side. There's a slight dead zone to the direct front the of the boat, which some craft can slip through, thus avoiding the torpedoes. The G7as, especially when the "Torpedo Mode" modification is installed, have substantially long range, and decent speed to boast. This allows them to strike enemies which are at a longer range to the battle, such as destroyers and cruisers, whom are sailing without change in direction or velocity.
The S-100 (1944) has access to 6 WBD depth charges. Having these in its possession allows for niche use in laying "extra temporary mines", that is, in that they're similar in use to mines. The S-100's high speed can be used to reach enemy choke points and lay depth charges in hopes that an enemy will approach unbeknownst to the charge and be damaged by its blast, however this sees very limited practical use in combat. These depth charges are sure to become more useful in the future, however, as submarine gameplay is introduced.
Usage in battles
The S-100 (1944) can be played as an aggressive assault ship focused on capping points and targeting players. It is recommended to use manually control the 20mm cannons as they can provide more firepower in a concentrated area than the 30mm cannon. If defending a cap point, turn the ship in an angled broadside to allow the quad 20mm cannon to fire while still allowing both the single 30mm and 20mms to fire.
Pros and cons
Pros:
- High mobility allows for rapid position changes and evasive action
- Proficient armament makes it effective against all but particularly large and heavily armoured vessels
- Torpedoes are effective weapons owing to their sufficient range and speed, and ergonomic launching position on the craft
- Excellent anti-aircraft capability, derived from an abundance of 20 mm cannons on 360° mounts, and a pair of MG15s
Cons:
- Average yet adequate survivability
- Front MK103/38 has a small clip and relatively long reload time
- Craft may have to be turned farther than other nations' equivalents to launch torpedoes at multiple targets, due to lack of spread
- Mountings of the MG15s facilitate limited use as they're suited to niche scenarios
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 long, take it to a separate article, taking a link to the article about the ship and adding a block "/History" (example: https://wiki.warthunder.com/(Ship-name)/History) and add a link to it here using the main template. Be sure to reference text and sources by using <ref></ref>, as well as adding them at the end of the article with <references />. This section may also include the ship's dev blog entry (if applicable) and the in-game encyclopedia description (under === In-game description ===, also if applicable).
Media
Excellent additions to the article would be video guides, screenshots from the game, and photos.
