Specifically, the mismatch in crew values caused by commander's 10% crew skill bonus. Outside of a crew of 1 commander only, 100% crew is a fiction. The client values, given for 100% crew, will normally be taken into battle with 110% crew skill members aside from specific functions, causing their actual performance to deviate from the expected client value. These differences are taken into account in tooltip boxes.

The T30 is an American tier 9 tank destroyer.

Experimental heavy tank. The vehicle was an early version of the T29 with enhanced armament. Two prototypes were built in 1945–1947 and underwent trials at the Aberdeen Proving Ground in 1948. Never entered mass production or saw service.

The T30 has a long history in World of Tanks. It started as a very good above average performing Tier X Heavy tank, that after several consecutive nerfs, ended at the back of the caravan. Its transformation into a Tier IX tank destroyer made this tank once again enjoyable to play. Its main weapon, the 155 mm T7, was formidable already in the Tier X arena, but when used against Tier VIII and sometimes even Tier VII targets, "devastation" is the only word that comes to mind. However, the T30 has a very weak hull, and under no circumstances can it afford to ignore low tier opponents. In the hands of a skillful player that knows how to properly use its strong points, the T30 can face any tank in-game and single-handedly change the course of the entire battle.

The T30 leads to the T110E4.

Player Opinion

Pros and Cons

Pros:

- Excellent gun mantlet armor and gun depression. Proof against most standard ammo when hull down

- 155mm AT Gun T7 with massive alpha and good penetration, mounted in a full traverse turret

- Large tracks covering the side armor, can sidescrape in a pinch

- High engine power and modest acceleration for its massive weight

- Hilarious yet sometimes frustrating fear factor with the 155mm gun, most opponents are reluctant to bear its shot

- Acceptable camo for its size

Cons:

- Requires great patience due to the 155mm gun's very long reload time and horrible gun handling

- All gun options are not considered close to being accurate, especially so when trying snapshots

- Weak hull armor and turret roof, not being hull-down or doing so on the same spot for too long are both unsafe

- Poor agility due to low traverse rate and bad terrain resistance, prone to flanking

- Priority target due to its vulnerabilities and fear factor, attracts a lot of artillery fire

Performance

The T30 is a nasty tank to fight against as it mounts the powerful 155 mm AT Gun T7, identical to the T95. The T30 can be quite scary to fight alone, especially if it manages to ambush you. Its slow turret traverse speed may allow agile tanks to flank and avoid being on the massive gun's receiving end. T30 drivers can attempt to counter this by turning the entire tank towards the target to bring the turret around faster. The best way to defeat it is to just gang up on it and strike at the hull armor. Fighting the T30 when it's in hull down is even more difficult. In this situation you may have to swarm from multiple directions simultaneously or try to land a shot in its turret roof, without resorting to high-penetration premium shells.

The T30 is similar to a tier IX heavy tank with fewer hit points but a massive gun. With the super weak hull and super strong turret in asset, hull down tactic suits perfectly so you should always seek to it. A tier X TD is about the only thing that can penetrate your turret by default. Artillery may fire from a high trajectory and deal heavy damage to your weak roof too. Other lighter armed opponents will likely aim for your turret's cupola to pen you, but a good counter to this attempt is to raise your gun barrel, wiggle the turret back and forth between shots, then proceed to aim after the enemy has shot. Use the T30 carefully, as it can contribute to victory in many ways. In ideal circumstances, the T30 is capable of anchoring a flank by itself, even in tier X games.

Note that as a tank with 360 degrees of turret traverse, you gain from a few uncommon traits: the T30 can benefit from traditional TD camo bonuses without breaking them by committing to not moving the hull when in a good position. Also when situation grows desperate, it might be not irrational to join shot-trading brawl altogether, since most HT in tier does around 440 damage per shot while you do 750 the same way. Two penetrating shots will cost your opponents usually more than half of their tank, which can be crucial and saves a lot of effort for teammates. Remember as a TD with little agility, healthy teammates can often help you more than carefully conserved hitpoint pool does in mid to late game.

Early Research

• The 120 mm gun carries over from the T28 Prototype. Install it immediately, as the stock 105 is inadequate. The top radio is also available on the T28 Prototype.
• Next, the stock suspension cannot hold the 155 mm, and you can't mount much equipment with it either. Get the top suspension.
• Then get the 155 mm cannon to bring the 750 alpha that opponents fear.
• Finally, get the top engine for a little bit better mobility.

Some players elect to use enhanced suspension if they want to prioritize researching the 155 mm or already have it available.

Historical Info

By the middle of 1944, combat reports from Europe describing the use of heavy tanks by the Germans stimulated new interest in the development of an equivalent American vehicle. The Pershing medium tank provided an answer to the early model of the German Pz.Kpfw. VI Tiger. However, although the latter was still in first line service, it had first been encountered by U. S. Army during 1943. By 1944, the Germans were introducing even more heavily armed and armored vehicles (Pz.Kpfw. Tiger II). Although for morale purposes the M26 Pershing was temporarily redesignated as a heavy tank, it clearly did not provide an answer to the problem. On 14 September 1944, U. S. forces recommended development and manufacture of four prototypes for a new heavy tank. Two of these were designated as the heavy tank T29 and were to be armed with the 105mm gun T5E1. The remaining two were designated as the heavy tank T30 and were to be armed with the 155mm gun T7.

History

Two T30 heavy tanks entered the test program at Aberdeen shortly after the T29. The first arrived at the Proving Ground in April 1948, followed by the second in July. Originally intended to have the same power train as the T29, the military characteristics of the T30 were changed in late 1945 to substitute the air-cooled Continental V-12 engine for the liquid- cooled Ford GAC. The new engine, designated as the AV-1790-3, developed 810 gross horsepower at 2800 rpm and was an early model of what became the standard power plant for American tanks during the next decade. The main objective of the T30 test program at Aberdeen was to evaluate the new engine with the CD-850 cross-drive transmission.

Technical info

T30 Technical drawings

The T30 hull was essentially the same as that of the T29, except for the changes to the engine compartment necessary to accommodate the air-cooled engine. The turret was also similar to that on the T29, but was armed with the T7 155mm gun. Only one coaxial .50 caliber machine gun was located to the left of the cannon in the T124 combination gun mount. The T7 cannon had a relatively low muzzle velocity of 2300 feet per second, but the 95 pound high explosive shell had a powerful demolition effect. Separated ammunition was used as with the 105mm gun in the T29. The cased-propelling charge weighed about 40 pounds: bringing the complete 155mm round weight to approximately 135 pounds. Thirty-four complete rounds were carried, and a spring rammer was provided for use with the heavy separated ammunition. Even prior to the tests, it had been expected that there would be considerable difficulty in handling the heavy ammunition inside the tank turret. On 24 July 1947, the U.S Army authorized the diversion of one T30 for the installation of experimental automatic ramming equipment, an automatic cartridge case ejecting mechanism, and a drive mechanism for indexing the mount for loading and returning the weapon to its previous position. The latter was required because the lack of space inside the turret, combined with the size and weight of the ammunition, permitted the loading of the gun only within a very limited range of elevation. This heavy tank was designated as the T30E1, the weapon and mount as the 155mm gun T7H1, and the combination gun-mount the T124E1.

T30E1 prototype

The sequence of operations when the cannon fired in the T30E1 was as follows; 1. The gun fired, recoiled, and returned to the battery position. 2. The gun automatically elevated or depressed to line up with the rammer tray. 3. The rammer-tray was extended. 4. A port in the rear of the turret bustle opened to allow the ejection of the empty case from the turret. 5. The gun breech opened and ejected the empty case. 6. A new projectile and cartridge case were lifted onto the rammer-tray. 7. The projectile and case were rammed and the breech closed. 8. The rammer-tray was withdrawn. 9. The gun automatically elevated or depressed to its original firing position parallel with the gunner's sight. To aid in handling the heavy ammunition, a power lifting device was installed in the T30 and T30E1 during the testing program. From the outside, the only obvious identification point on the T30E1 was the ejection port in the lower rear wall of the turret bustle.

T-series prototypes

The T29, T30, T32, and T34 series of tanks were used to evaluate numerous experimental components after World War II. Although too late for the war for which they were designed, they provided invaluable service in developing these components for later tanks. Much of the work which made the early AV-1790 engine and the CD-850 transmission a reliable power package utilized these tanks. Later, they were used in the development of other power train components such as the XT-1400 transmission, which was tested in the T30.
