In it the claim is a BAE 5-inch gun may be chosen to save on weight and space (and integration).

This is especially true if the River Class has weight issues in the forward part of the warship.

Further, if weight is an issue (and hence potentially leading to consideration to instead procure the BAE 5-inch gun), it entails a different fire control radar than the NA-30S Mk2 as I am not aware of the NA-30S Mk2 ever having been used with a BAE 5-inch gun.

I have read that both Saab CEROS 200 and Mk 160 Gun Computing System (GCS) (where Mk160 is paired with the AN/SPQ-9B radar) are known to have been interfaced to the BAE 5-inch gun.

I note in a speculative comparison between the Saab CEROS 200 and the Mk 160 Gun Computing System (GCS) where Mk160 is paired with the AN/SPQ-9B radar, reveals a disparity in weight and system footprint. The Mk160 + AN/SPQ-9B are much heavier.

I believe the total estimated system weight of the Mk160 GCS + AN/SPQ-9b could be as much as 2,200 kg (where ~1,500 kg of that is below decks) vs only about ~800kg to ~900kg for the Saab CEROS 200 (where maybe ~150 kg is below decks). This is very speculative. It does thou suggest the Mk-160 GCS + AN/SPQ-9B would have a higher weight impact in comparison to the Saab CEROS-200.

So Saab CEROS-200 is likely lighter, but , ... one speculation I have (where speculation is the operative word) is using a Saab CEROS 200 may forfeit the ability to use the BAE 5-inch gun's HVP (hypervelocity projectile) potential functionality for high-end missile defense - but the Mk160 GCS + AN/SQP-9B may provide such capability.
