Jura, are you serious or are you just here to troll?what a joke of a frigate! scandalous, sending the RN to Bangladesh level (and I don't mean to downplay the Type 056 export-version!)
The Arrowhead 140 design was the most flexible potential option of the three solutions offered. The others were a much lighter MEKO baseline or the untested "Leander" from BAE, which was also probably lighter and very risky.
Arrowhead 140 was the option of choice for pretty much everyone with a non-commercial interest in the Type 31. The Iver Huitfeldt is a good ship and larger than the Type 23. Really there's plenty going for it. The only real issue is the modules installed, but even then it can be upgraded in the future.
