Development started in 1942. In April 1943 the General Motors company produced the first prototypes. One of a few American tank destroyers manufactured on its original chassis, not on a tank chassis. The tank destroyer became the fastest armored vehicle, of this type, of World War II. A total of 2,507 vehicles were produced from July 1943 through October 1944.
The M18 Hellcat is a unique tank destroyer with its top speed of 72 km/h -- making it the fastest TD in the game (although historically it could go as fast as 92 km/h), and is also one of the most played tanks in World of Tanks. Armed with the high powered 90 mm AT Gun M3, the M18 Hellcat is a dangerous tank to fight. The Hellcat has negligible armor and an open turret so use your speed to avoid enemy fire or die quickly. The M18 Hellcat can scout and flank enemy positions to some degree but with the slow turret traverse speed, drivers will quickly learn it is not the best of roles. The Hellcat is very popular in tank companies along with the KV-85. In tight situations the Hellcat can be used as a scout tank, although it is not highly recommended due to the traverse speed on both its hull and turret, and the paper-thin armor.
The M18 Hellcat leads to the T25/2.

Pros and Cons
- Good damage, accuracy, aim time for its tier
- Excellent gun depression
- Very good camouflage values
- Above average view range
- High top speed
- HE shells are a death sentence for this TD due to an open-top turret, frontally-mounted transmission, and paper hull.
- 2nd worst penetration of all tier 6 TDs, along with Jackson
- Very slow turret & hull traverse speed, poor speed retention & backward speed, massively worse dispersion values than [[Jacks
- Mediocre acceleration with poor performance on soft ground due to high Terrain Resistance, and terrible reverse speed
- Fourth worst DPM out of all tier 6 TDs, only better than the SU-100Y, ARL V39 and Ikv 65 Alt
The M18 "Hellcat" is a very effective sniper and limited scout/ light skirmisher. Armed with a decent gun for its tier and provided with generous speed in exchange for being protected by something that resembles armor, use your speed, camouflage and turret to be able to fire from various locations and quickly relocate before opponents can return fire. Shoot-and-scoot tactics familiar to artillery will be very successful in avoiding fire. Do note while the Hellcat is indeed very fast, it has poor hull traverse and even worse turret traverse, equal to the M36 Jackson. Due to the M18's preferred play style, it is far more of an issue than on the M36 Jackson.
However, caution must be taken when playing with the Hellcat. Its notoriously thin armor makes high-explosive rounds extremely effective against it, especially the hull. Combined with the open-topped turret, it is the poster child for HE targets. It is also vulnerable to automatic cannons that many light tanks carry. It is also prone to module damage, and will lead to an untimely demise. The speed is also a point of caution: it may be fast in a straight line on hard ground, but it cannot reverse very quickly, turns rather sluggishly and tends to bog down on soft ground. This means that it will be harder to get out of sticky situations.
The M18 does not retain its speed during turns or when climbing up hills, since speed was derived from the lack of armor rather than a particularly powerful engine; the same engine as the T67 in a chassis that is 33% heavier. However, this does not prevent it from changing position rapidly. Use this to wreak havoc on enemy advances, as it has done in real life. By firing from multiple positions, it would be as if they were to engage a new target. Coupled with a preference to hull-down positions, this can slow down an advance considerably.
On the offensive, the 90mm AT Gun M3 can reliably engage heavy tanks one or two tiers above it, and the speed can be used to secure forward positions. The 90mm gun allows it to hold the position long enough for reinforcements to be brought up. However, some vehicles, such as the IS-3, T28 and the Tiger(P) will give the standard 90mm AP shot problems. However flanking or premium ammunition are always viable options, especially with a 72kph top speed and a potent 90mm gun.
In close combat, players have to turn turret well in advance to compensate for slow turret traverse and high speed. When you are in long range combat, use its camo factor and speed to get into advance positions where the enemy would not expect a TD to usually sit, retreating before they can overwhelm or flank you. This tank can scout if needed at the end of the round; you'll most likely be the fastest thing out there and also the deadliest. When stuck in close quarters with a heavier tank, your gun mantlet can sometimes surprisingly bounce some shells from enemy tanks. While it can hold corners down with peek-a-boo tactics, it is useless in a turning fight with a fast medium tank such as a Cromwell or Easy Eight. You will be certainly destroyed by these vehicles. Engage them at range and stick with teammates if it is likely to encounter these machines.
Do note that, like scout tanks, the Hellcat's vulnerabilities can be used as bait. Cooperate with your team to draw enemies into the line of fire, while giving your victims a nasty dose of 90mm shells too.
- If coming from the T67, the 76mm M1A1, top radio and top engine will carry over.
- If coming from the M10 Wolverine, the 76mm M1A2 and 2nd engine will carry over.
- Top engine also carries over from the scout line, the Shermans and the M7 Priest.
- Top radio also carries over from the SPGs.
- Top gun carries over from the M36 Jackson.
- Research priority should be M1A2 (if coming from T67) or top engine (if coming from the M10), followed by tracks, turret, 90mm gun and finally radio.
In December 1941, the Ordnance Corps issued a requirement for the design of a fast tank destroyer using a Christie suspension, the Wright/Continental R-975 engine, and a 37 mm gun. In light of experience gained in North Africa, the 37 mm gun was found to be inadequate and the design was changed to use a British 57 mm gun. During the development process, the design was further upgunned to a 75 mm gun, and then finally to the 76 mm gun. The Christie suspension requirement was also dropped, and replaced with a torsion bar suspension. The design was standardized in February 1943 and production began in July 1943. As a new design, the M18 incorporated several innovative maintenance features. The Wright R-975 engine was mounted on steel rollers, which permitted it to be disconnected from the transmission, rolled out onto the lowered engine rear cover, serviced and then reconnected to the vehicle. Similarly, the transmission could be removed and rolled out onto a front deck plate to allow inspection and repairs. The T70 prototype for the M18 first saw combat at Anzio, Italy, and production versions of the M18 were used in North-West Europe and Italy from the summer of 1944 onwards. In contrast to the M10 tank destroyer, which used the chassis of the M4 Sherman, the M18 Hellcat was designed from the start to be a fast tank destroyer. As a result it was smaller, lighter, and significantly faster, but carried the same gun as the Sherman 76 mm models. The M18 carried a five-man crew as well as 45 rounds of main gun ammunition, and an M2 Browning machine gun on a flexible ring mount for use against aircraft and infantry.The main disadvantages of the M18 were its very light armor, and the inconsistent performance of its 76 mm gun against the frontal armor of later German designs such as the Tiger and Panther. The open-topped turret (a characteristic which it shared with the M10) left the crew exposed to snipers, grenades, and shell fragments. The doctrinal priority of high speed at the cost of armor protection thus led to an unbalanced design. The problem of the main gun performance was remedied with High Velocity Armor Piercing (HVAP) ammunition late in the war, which allowed the 76 mm gun to achieve greater frontal armor penetration, but this was never available in quantity.
While the M18 was capable of high road speeds this attribute was difficult to use successfully in combat, but along with the high top speed was a commensurate ability to accelerate rapidly and change direction rather quickly. Although sustained travel at road speeds was hardly ever used outside of the Allied response during the Battle of the Bulge, most Hellcat crews found the higher speeds especially useful in a sprint to flank German tanks, which had relatively slow turret traverse speeds, and such maneuvering allowed the tank destroyer crew a shot instead into the enemy's thinner side or rear armor. In general, Hellcat crews were complimentary of their vehicle's performance and capabilities, but did complain that the open top created a cold interior in the Northern European winter of 1944-45. This problem was not helped by the fact that the air-cooled engine pulled a percentage of its cooling air through the crew compartment, creating in effect, a large armour plated refrigerator. It was not designed to do so, but it proved impossible to seal off the crew compartment entirely from engine induced drafts.
The only M18 variant which was produced in significant numbers was the M39 Armored Utility Vehicle, a turretless variation used to transport personnel or cargo or as a gun tractor. This version was armed with a single M2 machine gun on a flexible mount. 650 early production M18s were converted into M39s by removing the turret and fitting seats for up to eight men in the open fighting space. M39s saw combat during the Korean War, primarily as armored personnel carriers and munitions carriers, and were finally declared obsolete on February 14, 1957. About 100 M39s were transferred to the West German Bundeswehr in 1956, where they were used to train the reestablished Panzergrenadier armored infantry units. The M18 continued in production until October 1944, when the war was nearing its end. 2,507 had been produced by that time, at a unit cost of $57,500. Though all tank destroyer units were disbanded by the U.S. after the war, surplus M18s continued to see limited service.
The attack of 1st Battalion and the M18 Hellcat tank destroyers of the 705th TD Battalion near Noville together destroyed at least 30 German tanks and inflicted 500 to 1000 casualties on the attacking forces, in what amounted to a spoiling attack. A Military Channel historian credited the M18 destroyers with 24 kills, including several Tiger tanks, and believes that in part, their ability to "shoot and scoot" at high speed and then reappear elsewhere on the battlefield and therefore appear to be another vehicle entirely played a large part in confusing and slowing the German attack, which subsequently stalled, leaving the Americans in possession of the town overnight. The Hellcat, due to its 76mm gun, had major difficulty penetrating the glacis of Panther tanks. Due to the almost absent armor of the Hellcat and its use of high flash powder the Hellcat made a relatively easy target for German tank crews. Tank destroyers, in contrast to the pre-war doctrine governing their deployment, came to attack enemy armour from long range from an ambush position, acting in essence like self-propelled anti-tank guns. The Hellcat had a gun that could penetrate roughly 88mm at 1000 m. The average combat range noted by the Americans for tank vs. tank action was around 800m to 900m. This was just enough to penetrate a Panzer IV frontally, a tank designed in 1939. If facing a Panther, a Hellcat would be facing a tank with roughly 140mm of line-of-sight armor frontally. Hypothetically, if the Soviet Union decided to invade the rest of Europe during the war, the Hellcat would face the IS-2 with a glacis of roughly 200mm line of sight armor.
Tank Destroyer Doctrine
After World War II, many M18s were given to other countries. These were rebuilt and refurbished by Brown & Root in northern Italy in the late 1940s and early 1950s, and bear data plates that indicate those rebuilds. One of the users was Yugoslavia, which kept them in reserve until the early 1990s. A number of these vehicles were later used by the Military of Serbian Krajina and Army of Republika Srpska during the Yugoslav wars. One example was used on an armored train named the Krajina Ekspres (Krajina Express). Taiwan also operated several M18s until their chassis and hulls were worn out, at which point the turrets were salvaged and installed onto surplus hulls of M42 Duster anti-aircraft vehicles to produce Type 64 light tanks.

Historical Accuracy Errata
The 76mm Gun Motor Carriage M18 variant of the Hellcat had an actual top speed of 92 kph, making it one of THE most mobile tanks of WW2.
- One of its historical armaments, the 105 mm T12 howitzer, is missing. This configuration was known as the 105 mm Howitzer Motor Carriage T88.
- It actually was not equipped with a 90mm that M36 Jackson had. It was tested with 90mm though but was cancelled.
