I think there‘re some conflicting specs about Fatah II going around.
According to an article by Pakistani Qura defense media, there was a much slimmer, older Fatah II design before the new much heavier Fatah II was tested and revealed.
On 27 December 2023, the Pakistani military announced that it test-fired a new 400 km-range surface-to-surface missile, the Fatah-II.

In 2023, Global Industrial and Defence Solutions (GIDS), the commercial arm representing a number of Pakistan’s state-owned defence contractors, showcased a “Fatah-II” that was an evident evolution of the Fatah-I. This earlier Fatah-II inherited the core design attributes of the Fatah-I, but with an improved range of over 250 km and accuracy of 10 m circular error probe (CEP), compared to the Fatah-I’s range and accuracy of 140 km and 50 m CEP, respectively.
In contrast, this ‘new’ Fatah-II not only offers a far greater range at 400 km, but it also seems to be a larger missile. For example, the Fatah-I used an eight-cell launch system (which the original Fatah-II design would have likely reused), while the new Fatah-II seems to leverage a twin-cell system. Finally, the design of the new Fatah-II also exhibits several key differences, such as the lack of fins on the nosecone, for example.“
1. Older, slimmer Fatah II with cone wings, 150 kg warhead and 250 km range with CEP <10m

2. Tested new heavier Fatah II (domestic version) with 400 km range and CEP <50 m or CEP <10 m?
(exact diameter? warhead mass?)
3. Export version shown at WDS 2024 with 290 km range, 365 kg warhead and CEP <50 m (exact diameter?
During WDS 2024, held in Riyadh from 4-8 February, Pakistan’s GIDS presented its largest stand ever, which included the Fatah-II MRL.

This CEP <10 m for the new 400 km Fatah II reported widely might be false stemming from data of the smaller Fatah II design shown on GIDS producer website.
If the CEP is in reality <50 m, that‘s worse than similar caliber guided multi-launch rockets with high precision from US, Israel, Korea or China.
Edit: warhead data, link added.
