ZTZ59 (122mm)


TL;DR: Very rare Eritrean modification of ZTZ59 with 122mm D-30M.

Note: Information regarding this vehicle is incredibly scarce, the following is the best I could do

History
Eritrea, officially the State of Eritrea, gained de jure independence from Ethiopia in 1993, following its annexation in 1962, and the decades-long Eritrean War of Independence. Eritrea’s EPLF (Eritrean People’s Liberation Front) was briefly allied with the Ethiopian People’s Revolutionary Democratic Front that toppled the Derg – Ethiopia’s Marxist-Leninist regime – in 1991, and used various tanks during this conflict.

However, not long after official independence, Eritrea invaded Ethiopia – starting the Eritrean–Ethiopian War from 1998-2000. It was in this conflict that the mysterious ZTZ59 (122) was constructed and used in battle.

Ethiopia first got their hands on T-54/55s from the Soviet Union, with around 900 T-55s delivered in the late 70s and 80s, and another 230 from other Eastern Bloc countries up to the late 1990s – Bulgaria delivered another 100 from 1999-2002.

However, the only two images of this vehicle show the hull belonging to a Chinese ZTZ59 (Type 59), distinguishable by a few key details like the sideskirts, and the headlights on the upper front plate. No sources that I’ve found mention deliveries of ZTZ59s to Ethiopia or Eritrea, and so I’m unsure how it ended up there. It could simply be a delivery that went unreported.

This vehicle is said to have been constructed for service during the 1998-2000 war, specifically seeing action near Badme in Eritrea in 1998, a town at the heart of the war. Its whereabouts since are unknown, most likely destroyed in fighting, or scrapped after the war – no images have surfaced since. One other image shows what appears to be at least three similar vehicles, but due to the angle, it’s unclear whether they are ZTZ59s, or T-54s/55s.

  • Three 122mm-armed T-54s/55s/ZTZ59s

Characteristics
The vehicle was constructed as an impromptu SPG, potentially after its turret was blown off or damaged. A 122mm D-30M is placed on the hull, with only a small gunshield around the front, and what appears to be lowerable side-skirts.

The 122mm D-30M is a modernised variant of the 122mm D-30, with a new double-baffle muzzle-break and an improved base plate. The D-30M can fire a variety of shells, with at least 2 HE rounds, a couple of HEAT-FS rounds (one of which has 460mm penetration), as well as smoke rounds. The gun of the 2S1 Gvozdika is modified from the D-30 and uses the same shells, and so should give a good idea of its performance.

The hull of the vehicle appears unchanged. The ZTZ59 has 100mm of frontal armour, sloped at 60°. The sides are 80mm at 0°, and the rear is 45mm at 16°. The tank has a 520hp engine, giving it a top forward speed of 51km/h and reverse speed of 8km/h. It weighs 36t, turret included. As such, this modification probably weighs around 33t – the hull alone weighs roughly 30t (WZ651/Type 75 ARV weight is 31t, with dozer blade and other attachments), and the D-30M weighs 3.2t.

Conclusion
The ZTZ59 (122) would be a fun premium or event vehicle for the Chinese tree, with a powerful cannon and decent frontal hull armour, but with very poor crew protection. It would probably sit around 7.0.

interesting. which nation do you think it should go to? China or Russia, or maybe both?

Either work. It’s a Chinese hull, which gives them a point, but equally, China is more supportive of Ethiopia (in recent years selling them large numbers of APCs + SPGs, among others) and Eritrea is closer to Russia (although still has good relations with China).

I was asking because, as you said, it could either be Russian T-54/T-55 hulls or Type 59 hulls, maybe both

Sure, and in that case, ZTZ59 to Chinese tree, T-54/55 to Soviet tree.

But, the ZTZ59 is a bit more unique (and the one focused on here), so I’d prefer that. Ethiopia also seem to have a 122mm-armed T-54/55, although it hasn’t been fully revealed – that could be one for Russia.

  • Here, on the right

Fair enough.

Pretty cool. I can see this being a non-tech tree vehicle for China. I assume that this has good turret traverse.

As USSR main I would say that for China it will be much better. We really dont need that in TT and we have better options to add. But if it were added to the USSR (T-54/55 variant) then I will not complain.
