Description

The Type 99 155 mm SPH (99式自走155mmりゅう弾砲) is currently one of the 155 mm howitzers in JGSDF service as the direct replacement of the obsolete, shorter-barreled Type 75 155 mm SPH. The JGSDF had already planned for a replacement of the Type 75 SPH as early as 1985; development began in 1987, with MHI responsible for the extended hull based on the chassis of what would become the Type 89 IFV, while JSW developed the weapon systems with a domestic 155 mm L/52 howitzer. The new SPH was ready for trials in 1996, and tests were conducted in 1998, with the first four SPH units delivered to the training corps. However, due to the high unit price, the complete replacement of all Type 75 SPHs will be fulfilled by the Type 99 SPH alongside a new, wheeled Type 19 155 mm SPH.

Introduced in Update "Air Superiority" as the second SPH of JGSDF, the Type 99 is equipped with a Japanese NATO standard 155 mm howitzer and shares similar shells, but due to the increased length, it offers a whopping 940 m/s shell velocity. The new gun system retains the relatively fast gun traverse speed and new autoloader for faster reload; meanwhile, tank crews have to beware of the rather underpowered engine and huge size; enemy commanders can easily spot this long-nosed "lying Pinocchio" from afar.

Instead of opting for NATO SPHs, the JGSDF initiated plans to develop a domestic SPH, resulting in the creation of the Type 99. The most distinctive feature of the Type 99 is its notably long 155 mm L/52 howitzer, contrasting with the short chassis based on the Type 89 IFV. This characteristic earned it the nickname "Long Nose." However, this length poses a challenge as it makes the Type 99 easily identifiable on the battlefield. With an overall length, including the barrel, measuring 11.3 m, it cannot move unnoticed unless enemies are overly focused on a specific area. The overall protection comprises 20 mm RHA plates for both the chassis and turret. This means that any .50 calibre heavy machine gun won't struggle to target the crews within 300 m, let alone autocannons at even longer ranges. Taking cover and staying behind the frontline is advisable to prolong its survival. Extra caution is needed to conceal the rear of the turret, as the last thing commanders want is to witness the detonation of the 30 shells and charges located directly behind it, creating a significant explosion.

Equipped with a mechanized loader, the Type 99 operates with a smaller crew than NATO/Warsaw Pact SPHs, numbering only four individuals. While the SPH is rather spacious, the driver and assistant loader are rather spread out while the gunner and commander are squeezed together, making for an easy collateral. This crew composition will usually result in needing at least two well-placed AP shots frontally, or one side-on hitting all three turret crew in a single shot. Other possibilities of one-shots are by overpressure, a sensitive APHE fused shell into the turret or the ammo rack.

As the hull was developed from Mitsubishi's Type 89 IFV with an extended length, the Type 99 retained the identical 6SY31WA V8 engine and transmission. While the 50 km/h speed and its 12.1 hp/t ratio might not seem particularly impressive, it does offer a -30 km/h reverse speed for a quick retreat.

To align with the late Cold War trend of self-propelled howitzers featuring long barrels, the Type 99 is equipped with a domestic 155 mm L/52 howitzer by JSW. The gun system boasts 30 shells in storage with an autoloader, enabling a firing rate of one shot every 7.5 seconds. Although not as rapid as the Bkan 1C at 3.2 seconds, this rate is more than sufficient for engaging tanks at its tier, which typically have longer reload times. The ballistics remain relatively straight due to its impressive 940 m/s velocity, facilitating easier long-range engagements. An area where the Type 99 excels is a supporting role.

However, caution is advised to avoid overextension, especially with the barrel exposed behind cover, as this may lead to the gun's disablement and, eventually, the Type 99 itself.

Ammunition

  • M107: NATO standard 155 mm HE shell, providing a reasonable 9.1 kg TNTe explosive mass.
  • M107(PF): M107, but equipped with a proximity fuse. The excellent velocity of the L/52, coupled with the proximity fuse, makes it a versatile ad-hoc AA shell.
  • L15A2: The pinnacle of NATO 155 mm shells, it offers an impressive 14.8 kg TNTe explosive mass. It has the potential to obliterate even the most heavily armoured vehicles.
  • M110: NATO Standard 155 mm Smoke shell.

Usage in battles

With a very high shell velocity of 940 m/s but low armor and a high profile, the Type 99 155 mm should be played as either a sniping vehicle or an anti-air vehicle. With the L15A2 high explosive shells, which have an explosive mass of 14.8 kg of TNT, it can destroy every vehicle at its rank and higher with a well-placed shot between the hull and the turret (Even the Maus or the Object 279 heavy tank). The hull of the Type 99 155mm also has a large empty spot without any important modules, meaning that some enemy shells will just go through the hull without activating the explosive fuse, creating little to no damage. Your most problematic enemies you have to keep an eye of are other vehicles with large caliber cannons or vehicles with autocannons. Avoid artillery at any cost, since the chance of getting hit by the artillery is much higher than other tanks due to its very large profile of the Type 99 155 mm.

Since the HE shells don't have a tracer mark while firing, shooting at an enemy group from a long distance while staying near cover is the best way to go to not be seen. The Type 99’s engine has very good backward speed of 31 km/h (RB). Meaning that if a situation becomes too hot, shooting a smoke shell on the ground while driving backwards is the safest way to retreat out of a dangerous situation. Alternately, the Type 99 can be played as an excellent anti-air vehicle to shoot down planes or helicopters nearby or from long distance. The even faster reload of only 7.5 seconds (from its predecessor Type 75 SPH with its 10 seconds reload), which also stays the same when its loader gets knocked out thanks to its autoloader and a very fast shell velocity for a caliber of 155 mm can make it very deadly for enemies in the sky. But make sure to equip the M107 (PF) HE shells when doing so. The engine compartment is also frontally placed and separated by a 5mm steel plate from the rest of the crew. Which means, that when the frontal hull gets hit, the engine can soak up the entire amount of potential damage the shell was about to unleash. Leaving the rest of the components and the crew itself unharmed. One of the major downsides of the Type 99 is the very little amount of gun depression of only -2 degrees, which can be difficult on rural and hilly maps.

Pros and cons

Pros:

  • Excellent shell velocity of 940 m/s (for a SPH)
    • Can make the M107 (PF) a reliable AA shell
  • 7.5-second auto-loader
  • 30 shells in the ready rack
  • 20 mm RHA armour offers a balance of protection without excessive weight
    • Thin enough to avoid triggering most APHE fuses
    • Effective protection against HMGs at longer ranges
  • Moderate mobility with a respectable -30 km/h reverse speed
  • Large and spacious
    • Requires more than one penetration

Cons:

  • Limited protection with 20 mm RHA armour
    • Minimal defense against shell penetration
    • In close-quarter combat, vulnerable to heavy machine guns
  • Relatively small crew size
  • Large and easily recognizable target
    • Very long barrel can be exposed when positioned behind cover
    • only -2 degrees of gun depression can be very difficult on maps with hills

History

Describe the history of the creation and combat usage of the vehicle in more detail than in the introduction. If the historical reference turns out to be too long, take it to a separate article, taking a link to the article about the vehicle and adding a block "/History" (example: https://wiki.warthunder.com/(Vehicle-name)/History) and add a link to it here using the main template. Be sure to reference text and sources by using <ref></ref>, as well as adding them at the end of the article with <references />. This section may also include the vehicle's dev blog entry (if applicable) and the in-game encyclopedia description (under === In-game description ===, also if applicable).

Media

Excellent additions to the article would be video guides, screenshots from the game, and photos.
