Survivability and armour

Helicopters have a unique role on the battlefield and fitting them with armour is not as easy as it is on a tank or on a jet. The helicopter's setup is such that it must take off and land vertically, hover and fly and as the aircraft gets heavier, bigger and heavier equipment are needed to balance until you are left with a massive helicopter which cannot fly or do its intended mission. The Huey balances this out with a vehicle which can manoeuvre as needed and carry a decent payload whether people or weapon systems.

The UH-1B does not fly with any protective armour or bullet-proof glass, which if installed would decrease the UH-1's ability to complete its mission. As such, the pilot must take this into account and fly the helicopter accordingly. Bull rushing right into the middle of a battlefield usually ends with disastrous results as the without armour, the Huey has nothing but thin metal fuselage coverings to protect the crew and vital equipment. The engine, transmission, main rotor and tail rotors are all exposed to fire from missiles, rockets, cannons and even small calibre machine guns. The pilot must be aware of their surrounds and work to fight from the enemy vehicles blind spots or weak sides, because a burning and crashed helicopter only pads the enemies' score-count. Pick and choose your battles to preserve the helicopter.

But the "thin metal fuselage" is still a "metal", it would provide minor, temporary protection for the interior modules (i.e. Fuel, Transmission, Engine, Crew, etc...). This means that calibers that are 7.62mm and below could potentially be stopped by the fuselage for a few several hundred shots until the fuselage starts giving warning when it slowly becomes yellow or orange.

Armaments

Offensive armament

Main article: M129 (40 mm)

The UH-1B can be outfitted with the following ordnance after unlocking the tier II Weaponry module M129:

  • 1 x M129 40 mm Grenade Launcher (150 RPG)

The UH-1B can be outfitted with the nose turreted M129 Grenade Launcher after researching and purchasing the tier II Weaponry module M129. The M129 is a grenade launcher which can fire 40 mm grenade shells at the rate of 400 rounds per minute with a muzzle velocity of 850 ft/s (260 m/s). An upgrade from the old M75 and redesigned, the torque produced from firing the weapon was eliminated and recoil was greatly reduced. To ensure safe operation of the M129, when the trigger finger releases the firing trigger, the launcher automatically recenters itself and points forward (safe position) before firing can be resumed.

The ammunition used is a 40 x 53 mm high-velocity grenade, the default in War Thunder is the high explosive anti-tank grenade (HEATGR). Rounds from this launcher are good at peppering lightly armoured vehicles, vehicles with open crew tops and heavier armoured vehicles which may have weak spots to exploit.

Suspended armament

The UH-1B can be outfitted with the following ordnance:

  • 38 x FFAR Mighty Mouse Rockets (default loadout)
  • 72 x FFAR Mighty Mouse Rockets (XM159 modification)
  • 6 x AGM-22 missiles (M156 AGM modification)
  • 2 x 7.62 mm M134 Minigun (XM-18 modification)
  • 2 x 7.62 mm M134 Minigun and 38 x FFAR Mighty Mouse Rockets (XM-21 modification)

The UH-1B is a real workhorse utility helicopter which can pack a punch with several different weapons load-outs and configurations utilising rockets, guns and missiles. Selecting a single type of weapon to fly into battle with or mixing it up will allow the pilot to mix and match as necessary for the upcoming fight. The M134 with it's almost 6,000 rounds-per-minute fire were an early fixture to helicopters as they can fly low and slow allowing them to pivot on the battlefield as necessary to take out personnel and light armoured vehicles. While initially not doing much damage being rifle calibre bullets, if the enemy does not move to avoid the fire, they will start taking on more and more damage. The M134 is also good for clearing trees and exposing hiding positions of armoured vehicles providing a better shot for harder hitting weapon systems. Note that unlike the fixed forward-facing XM-18 gun pods, the XM-21 mounts for the M134 Miniguns are flexible and can be aimed almost 90° to either side, as well as nearly straight up and straight down, providing a key advantage especially when encountering enemy helicopters.

Due to weight and recoil issues of autocannons, helicopters typically have a workaround which allows them to have similar firepower without the drawbacks. The UH-1B can be outfitted with the FFAR Mighty Mouse rockets which just needed to be aimed at the target and fired. The Mighty Mouse rockets, when launched, have fins which flip out to spin-stabilise them and guide them in as straight of a path as possible without any further guidance. While a single rocket can inflict some severe damage including shooting down bomber aircraft, typically one rocket will not be enough. Effectively the rockets work like a cannon with a shotgun pattern, where they pack a punch like a cannon, but have the accuracy of a shotgun and typically requires firing off several at a time to ensure a few will hit the target. The UH-1B can be outfitted with two amounts of the rockets, either 38 when stock or mixed with twin M134 Miniguns, or a total of 78 rockets when utilising them on both pylons. With the ability of the helicopter to swoop in and reorient towards a target in a matter of seconds, rockets can be streaking towards their target before the enemy has the chance to either notice or even swing a gun around to counter. Mighty Mouse rockets pack a punch, however, may not have enough ummph to get through some of the thicker skinned vehicles found on the battlefield.

Not without a heavy-hitter, the UH-1B can dish out damage with unguided rockets; however, to tackle some of the armoured goliaths rolling around on the battlefield, it needs something bigger! To meet this need, six AGM-22 manual to command line of sight (MCLOS) wire-guided anti-tank missiles are installed. Knowing the location of an enemy tank allows the helicopter pilot to take evasive action while setting up to fire off a missile. Using structures and terrain as a shield, the helicopter pilot can fire off a missile and then guide it to the target without being a target itself. It is vital to fire, hit and then move as a sitting helicopter makes for an easy target and while guiding a missile to the destination, the pilot can get tunnel vision and not realise inbound threats to their position.

Usage in battles

The UH-1B is a utility helicopter, therefore not built for speed, protection, and maneuverability, so instead the pilot must rely heavily on medium to long range engagements using its AGM-22 missiles. The typical tactic of the AH-1G where the pilot doesn't have access to AGMs leaves them no choice but to go directly near or behind the front line will prove hard for the UH-1B, since the UH-1B is not maneuverable and fast enough to do it, but if the pilot hasn't unlocked the AGMs yet, the pilot doesn't have a choice but to temporarily bring back the AH-1G tactics until the AGMs are unlocked.

If using the AGM-22 missiles, it is better to be more than 1 kilometer away from the target to avoid small arms fire (7.62mm) especially tanks armed with 12.7mm guns, and also try to be hidden in a place where you can look, shoot-through then hide again as modern MBTs are capable of helicopter engagements such as the Soviet/Russian tanks that are armed with ATGMs that are designed to shoot down helicopters of all kinds efficiently and with precision. Keep in mind that the UH-1Bs AGMs have very limited range yet 3kms is an already decent range, but below average, the AGM is also subsonic that only travels 190m/s or mach 0.55, this means it will take more than 5 seconds to reach a target from 2 to 3 kilometers away. SPAAGs that are only armed with 20 to 40mm auto-cannons and target-tracking modules will also have a hard time targeting you from 2 to 3 kilometers if you're on evasive maneuvers, most SPAAGs are also hull breakable from the turret and can be targeted safely from 2.5 to 3 kilometers away if it hasn't detected you on radar or visual range.

History

The United States Army identified in 1952 a need for a new general utility helicopter which could also serve as medical evacuation (MEDEVAC) and instrument training helicopter too. The current inventory of helicopters had several flaws which the Army wanted to overcome including being too large, underpowered or extremely complex to maintain. The Army wanted a workhorse that was easy to maintain and have a fairly small profile. Twenty companies participated in the bidding process and in 1955, Bell Helicopter was selected to build three copies of the Model 204 for evaluation, and this version was designated XH-40 (Experimental Helicopter-40).

The XH-40 was built with the Lycoming YT52-L-1 (LTC1B-1) turbo engine helicopter, the first non-piston helicopter tested by the military and first flew in 1956. Even before the prototype had flown, the Army put in an order for six YH-40 service test aircraft in which they could field test to determine how it would work under military unit operations. Proving successful, Bell was awarded a contract to build another 100 helicopters which were designated HU-1A (Helicopter Utility-1A) and hence was officially named "Iroquois". Iroquois ended up being a mouthful for people to say, so a nickname developed from the HU-1 designation which ended up being pronounced as "Huey" and stuck. In September 1962, the Department of Defense changed up the aircraft identification system to streamline between all of the different aircraft and their variations and changed the HU-1 to UH-1 (Utility Helicopter-1). Even with the change, the official Army name and the new DOD designation was rarely used as Huey was so well recognised as the name, that is what was to most people.

Unfortunately, with all of the positive feedback received for the YH-40, service tests performed by the Army found the T53-L-1A engine was found to be underpowered and could not perform to the level that was needed. Bell proposed to swap the T53-L-1A engine with the T53-L-5 engine, upping the shaft horsepower from 770 to 960 (570 kW to 720 kW) and extended the cabin to accommodate more people, up to 7 passengers or four stretchers and a medical attendant. The first production of the new helicopter UH-1B was delivered for service in 1961.

Several aerodynamic deficiencies of an armed UH-1B was explicitly identified not having enough engine power to lift the necessary weapons systems. The UH-1C was developed to overcome these problems by upgrading the helicopter with the T53-L-11 engine which had 1,100 shaft horsepower or 820 kW. The UH-1B helicopters which were in the service of the Army at the time were also upgraded with the new engine. Several adjustments were made to the UH-1C which included a new rotor-system, however, like many things which are upgraded, domino effect also requires other components and modules also to be updated. A larger diameter rotor was installed to counter blade stall during dives which required the tail boom to be extended and larger synchronized elevators to be added. While operating in military operations, it was determined necessary to add a redundant hydraulic control system to allow for continued operation in the event of a failure in one system. Larger fuel tanks allowed for further range with the total useful load capacity topping out at 4,673 lbs (2,120 kg). Mid-1966 saw the line production of the fully upgraded UH-1C helicopter.

Huey model 204 helicopters were a huge success and were put to use in several different capacities. However, the Army wanted another version which facilitated the carrying of more troops which spawned the Model 205. Bell adjusted by extending the HU-1B’s fuselage by a total of 41 in (104 cm), boxed in the transmission and was able to add four more seats, two on each side of the transmission box facing out the side doors. With the side doors being easily removable, options to fly without doors made for quick loading and unloading of the helicopter which could now accommodate 15 persons, including the crew and could now hold six stretchers and a medic. First flown in 1961, the 205 took on many of the same upgrades as the UH-1C including the T53-L-11 which enabled usage of multiple types of fuel. Prototypes of this helicopter were designated YUH-1D, and the final assembly line aircraft was called the UH-1D.

This helicopter while still under evaluation the Army sent it to Vietnam in 1962 where it began operations. Initially only required as a general utility, MEDEVAC, and an instrument trainer, this helicopters role also expanded to include but not limited to air assault, cargo transport, search and rescue, electronic warfare and eventually ground attack.

During the Vietnam War, the UH-1 earned several other nicknames other than "Huey" which quickly identified to troops what role the helicopter had been outfitted for. Gunship versions of the UH-1s were identified as "Frogs" or "Hogs" if they carried rockets while if they just carried guns, they were identified as "Cobras". Troop transport versions were called "Slicks" due to weapon pods being absent on the external pylons while they did retain their door gunners. Later in the war from 1967 to 1968, the gunship Huey’s were replaced by the new AH-1 attack helicopters.
