While the explosive weight of the “RP-3 rocket” mounted on aircraft is 6.35 kg, the explosive weight of the “RP-3 rocket” mounted on the Cromwell V (RP-3) is only 5.44 kg.
We request that the development team adjust the explosive weight and penetration power of the “RP-3 rocket” mounted on the Cromwell V (RP-3).
If it’s a bug, report it at Community Bug Reporting System. Remember to add enough sources that supports your claim(s).
A year ago someone reported an issue with the RP-3 explosive filler here: RP-3 Incorrect H.E. Filler, suggesting a change in filler from 5.44kg to 6.35kg. Seems like the devs fixed it for the air launched RP-3s but forgot the Cromwell. Should be straightforward to report.
How do I do this? I’m Japanese and don’t really understand English. I actually managed to post this by translating it with DeepL.
