Description

The M-class, M-17 is a rank German sub-chaser with a battle rating of (AB), (RB), and (SB). It was introduced in Update "Direct Hit".

General info

Survivability and armour

The M-17's armour is decent for its rank, being able to shrug off small to medium-calibre rounds from torpedo boats. However when facing larger-calibre guns from other gun boats and destroyers, the armour lacks protection, especially the turrets which can be disabled easily. The fuel tanks are located in the centre of the hull which can cause frequent fires. However it can still take many large destroyer rounds to destroy the ship. It is preferred to upgrade the armour for even better crew and ammo rack protection.

The M-17 is very sluggish to accelerate and turn. Manoeuvres must be planned well in advance to avoid torpedoes and running aground. It is recommended to upgrade the rudder to improve turn time and the engine, propeller and crew to improve both acceleration and deceleration, making it a more potent gunship.

The two 10.5 cm main guns are very effective and have good reload time and muzzle velocity, able to knock out small boats in two or three well-placed hits. The upgraded armour-piercing L/4.4 Bd.Z is recommended for hardened targets such as armoured boats and gun ships but is not very effective on one-to-one with destroyers. The arc of fire favours a broadside attack or angling about 45 degrees to the target.

Secondary armament

The M-17 is fitted with multiple 20 mm cannons which are effective against small boats and, being radar-guided, is accurate against low-flying aircraft less than 2 km. The volume of fire and short reload time contributes to a large volume of fire that can repel enemy attacks. However the quad 20 mm are mounted towards the stern and the front is only covered by the two port and starboard cannons.

Additional armament

There are no light machines guns on the M-17, nor are there 37 mm cannons like the M-802. There is an upgrade to a powerful anti-submarine bomb mortar, but its use is very limited and opportunistic in-game. The slow travel makes mines difficult to use.

Usage in battles

The M-17 is similar to the M-802 but without the reinforced engine armour or the torpedoes. As with most sub-chasers, it's slow and won't arrive first to the battlefield, but the ship has well armoured 105 mm main guns with enough fire power to hull break many ships or pen destroyers with base fuze HE in desperate scenarios. Facing destroyers is ill-advised as they have higher caliber guns in larger quantity.

This ship should be used at long range to allow for more time to react to smaller vessels as well as the torpedoes as the slow speed of this ship makes it a torpedo and artillery magnet. In a pinch, the vessel can litter a capture point with mines, albeit they require a lot of skill and patience to use and often act as an extra ammo rack prone to detonate.

To counter this vessel, the most vulnerable place is the bow where the ammo rack is. A single bomb or torpedo there is guaranteed to sink the vessel. The safest option would be swarming the M-17 as multiple ships at different flanks will overwhelm the ship easily.

Pros and cons

Pros:

• Heavy-hitting main armament can knock out many coastal vessels
• Coastal spawn allows the vehicle to face small vessels
• Fast reload rate
• High survivability
• Can carry many mines

Cons:

• Sluggish speed makes this ship vulnerable to torpedoes
• Outgunned by destroyers
• Massive/tall target
• Low calibre AA is ineffective at long ranges
