Design

The MH-60S Seahawk is a four-bladed, twin engine, rotary-wing helicopter designed to transport troops or cargo into battle.

Armament
It is armed by default with twin 7.62 mm medium machine guns fitted to side doors located just behind the cockpit. Each M240 is pre-loaded with a single 100-round belt box of and has a further two boxes in reserve (for a total of 300 rounds per side gunner).

Features
The Seahawk essentially fills a gap between the UH-1Y Venom Light Utility Helicopter and the larger MV-22 Osprey V/STOL. It can transport six more passengers than the UH-1Y (7) but carries eleven less passengers than the MV-22 (24).

The main difference is that the Seahawk, being much smaller than the MV-22, can easily fit in Landing Zones that would otherwise be too difficult for the latter to fit in (or outright impossible depending on whether there are trees/tall objects in the way). On the other hand, the Seahawk is better armoured than the UH-1Y and can take slightly more punishment than the former before it suffers from any critical component failures.

Drawbacks
Although the Seahawk is actually armed (unlike the MV-22), it is not fitted with stub wings and is unable serve in a light gunship role like the UH-1Y can.

Because the side door gunners only use 7.62 mm machine guns as opposed to Gatling guns, they also cannot suppress enemies as effectively during and after landings due to their lower and non-adjustable rates of fire (incidentally, an issue that its U.S. Army counterpart does not have). Furthermore, the UH-1Y can serve as an airborne Forward Air Control asset since it has access to a laser designator whereas the Seahawk has no such capability.

Overall, the Seahawk works better as a battlefield taxi for quickly transporting a squad's worth of troops into or out of battle. For situations that don't require its expanded passenger capacity however, the UH-1Y will always prove to be more useful.

Crew Capacity
Including the crew, the Seahawk has a seating capacity of thirteen personnel. This consists of the pilot, the two side gunner crew chiefs, and up to twelve passengers who sit on back-facing seats in the centre compartment (the co-pilot is considered as the thirteenth passenger).

Protection: Hitpoints

The Seahawk has a base armour value of 35.

LEGEND
Green = Hull
Orange = Engines
Maroon = Instruments
Yellow = Main rotor
Dark blue = Tail rotor

Hull

The hull can withstand up to 35 points of damage. Depletion of its integrity will always result in a total loss.

Engines

The helicopter's engines can only take a maximum of 8.75 points of damage before they fail. 100% of incoming damage to either engine will always be shared with the helicopter's main "health" pool. Destroying the engines has the potential to result in the helicopter's destruction if it is at or near critical "health" status.

Instruments

The cockpit's flight instruments are able to take only 5.25 points of damage before they fail. 100% of incoming damage will always be shared with the helicopter's main "health" pool. Destruction of the instruments also has the potential to cause the helicopter to explode if it is at critical "health" status.

Main rotor

The main rotor can only withstand a maximum of 10.5 points of damage before it fails. 30% of incoming damage will always be shared with the helicopter's main "health" pool. Destroying the main rotors will not cause a total loss by itself. However, it is possible for this to happen if the Seahawk is at critical "health" status.

Tail rotor

The tail rotor is able to take up to 7 points of damage before it fails. Only 10% of incoming damage will be shared with the helicopter's main "health" pool. However, it is possible for the Seahawk to explode catastrophically if it is at critical "health" status at the time of the tail rotor's destruction.

Protection: Armour

The Seahawk's airframe and its components are protected by various metals and plexiglass:

• All of the flight cabin's windows are entirely made out of panes of (non-bullet resistant) plexiglass that have a thickness of 2 millimetres.
• The engines are made out of iron.
• The Seahawk's tail structure, main rotors, tail rotors, and most of the fuselage (excluding the forward section of the fuselage underbelly) are made out of metal plates that have a thickness of 2 millimetres.
• The underbelly of the forward fuselage (but not the tip of the nose) and cockpit dashboard are protected by metal armour plates.

It should be noted that none of the flight cabin's windows are bullet-resistant. The plexiglass is not sufficiently thick enough to block small arms projectiles.

Armament

Both crew chiefs man the side door-mounted M240 7.62 mm medium machine guns. Neither of the M240s are fitted with enhanced vision or magnified optics:

M240

Ammo parameter	Value
Base damage value	12
Aerodynamic friction	-0.0009324
Muzzle velocity (m/s)	834
Expected velocity (m/s)	900
Deflection angle (degrees)	10°

Side door 7.62 mm medium machine guns.

They can attain fire rates of up to 800 rounds per minute and have muzzle velocities of 834 m/s. Accuracy-wise, they have dispersion values of 0.0012 rad. It takes at least 5 seconds to reload a fresh belt box or to fully rearm from supply truck.

Manual zeroing is available, starting from a minimum of 100 metres up to a maximum of 800 metres (100, 200, 300, 400, 500, 600, 700, 800). By default, M240s utilise a zeroing of 300 metres. The gun mount allows for a maximum horizontal rotation of 150 degrees and a vertical rotation limit of 25 degrees elevation and 80 degrees depression.

Avionics

MAWS

The Seahawk has a Missile Approach Warning System that will warn the pilot if there are missiles that have successfully locked onto the helicopter are inbound towards it.

RWR

The Seahawk has a Radar Warning Receiver fitted. The pilot will be alerted if they are being locked onto by a radar-based targeting system.

IWR

The Seahawk does not have access to an Infrared Warning Receiver. The pilot will not be warned if an infrared-based weapon system is attempting to lock onto it.

LWR

The Seahawk is fitted with a Laser Warning Receiver. The pilot will be warned if they are being locked onto by laser-based targeting systems.

Trivia

• Unlike the Venom, the Seahawk was "upgraded" with the ability to use countermeasure flares with the release of the Operation Arrowhead expansion pack.
• Despite its in-game Armoury Description stating that it has a seating capacity of eleven, the Seahawk actually supports a maximum of thirteen passengers (the co-pilot counts as the thirteenth passenger).
• The latest Steam version patches (as part of the Community Configuration Project/CorePatch) changed seating position settings for the Seahawk so it is now possible for the crew and passengers to freely transition between seats (i.e. either of the door gunners can swap seats with the pilot/co-pilot and vice versa).
  • Two other fixes/gameplay changes were applied: the CCP added a warning sound effect if the Seahawk was damaged, while CorePatch enabled a Missile Approach Warning System for the pilot (Seahawks did not have a MAWS prior to CorePatch).
  • However, because both of its M240s feed from the same 100-round cloth boxes used by handheld M240 GPMGs, the Seahawk was also indirectly nerfed by CorePatch due to their muzzle velocities being reduced to 834 m/s (down from the original 900 m/s).
